| 2 | A restoration-promoting integrated floating bed and its experimental performance in eutrophication remediation显示文摘Numerous studies on eutrophication remediation have mainly focused on purifying water first, then restoring submerged macrophytes. A restoration-promoting integrated floating bed(RPIFB) was designed to combine the processes of water purification and macrophyte restoration simultaneously. Two outdoor experiments were conducted to evaluate the ecological functions of the RPIFB. Trial 1 was conducted to compare the eutrophication purification among floating bed, gradual-submerging bed(GSB) and RPIFB technologies. The results illustrated that RPIFB has the best purification capacity. Removal efficiencies of RPIFB for TN, TP, NH+ 4-N, NO-3-N, CODCr, Chlorophyll-a and turbidity were 74.45%, 98.31%, 74.71%, 88.81%, 71.42%, 90.17% and 85%, respectively. In trial 2, influences of depth of GSB and photic area in RPIFB on biota were investigated. When the depth of GSB decreased and the photic area of RPIFB grew, the height of Potamogeton crispus Linn. increased, but the biomass of Canna indica Linn. was reduced. The mortalities of Misgurnus anguillicaudatus and Bellamya aeruginosa in each group were all less than 7%. All results indicated that when the RPIFB was embedded into the eutrophic water, the regime shift from phytoplankton-dominated to macrophyte-dominated state could be promoted. Thus, the RPIFB is a promising remediation technology for eutrophication and submerged macrophyte restoration. | Yiming Guo Yunguo Liu Guangming Zeng Xinjiang Hu Xin Li Dawei Huang Yunqin Liu Yicheng Yin | 2014 | Journal of Environmental Sciences2014，26，5： | 18 |

| 4 | Feasibility of bioleaching combined with Fenton oxidation to improve sewage sludge dewaterability显示文摘A novel joint method of bioleaching with Fenton oxidation was applied to condition sewage sludge. The specific resistance to filtration(SRF) and moisture of sludge cake(MSC) were adopted to evaluate the improvement of sludge dewaterability. After 2-day bioleaching, the sludge p H dropped to about 2.5 which satisfied the acidic condition for Fenton oxidation.Meanwhile, the SRF declined from 6.45 × 1010 to 2.07 × 1010s2/g, and MSC decreased from91.42% to 87.66%. The bioleached sludge was further conditioned with Fenton oxidation. From an economical point of view, the optimal dosages of H2O2 and Fe2+were 0.12 and 0.036 mol/L,respectively, and the optimal reaction time was 60 min. Under optimal conditions, SRF,volatile solids reduction, and MSC were 3.43 × 108s2/g, 36.93%, and 79.58%, respectively. The stability and settleability of sewage sludge were both improved significantly. Besides,the results indicated that bioleaching-Fenton oxidation was more efficient in dewatering the sewage sludge than traditional Fenton oxidation. The sludge conditioning mechanisms by bioleaching-Fenton oxidation might mainly include the flocculation effects and the releases of extracellular polymeric substances–bound water and intercellular water. | Changgeng Liu Panyue Zhang Chenghua Zeng Guangming Zeng Guoyin Xu Yi Huang | 2015 | Journal of Environmental Sciences2015，27，2： | 12 |
| 5 | Potential Benefits of Biochar in Agricultural Soils:A Review显示文摘Soil degradation,characterized by declines in nutrient status and simultaneous accumulation of pesticide residues,is a major problem affecting agricultural ecosystems.Previous studies indicate that biochar application to soil has promise as a practical method to alleviate these pressures:increasing crop yield and enhancing pesticide degradation.Here,we review the roles of biochar in both chemical and biological promotion of pesticide degradation and the potential benefits of biochar relating to the efficiency of fertilizer use,availability of nutrients,and nutrient exchange.Biochar typically has a high surface area featuring many functional groups,a high cation exchange capacity,and high stability.Major factors that impact on the nutrient retention characteristics of biochar(e.g.,feedstock,pyrolysis temperature,and application rate) are also discussed herein.Nonetheless,more studies of the long-term impacts on soil properties from biochar addition are still required before it can be possible to accurately quantify the sustainability of this approach to sequester carbon and restore soil function. | DING Yang LIU Yunguo LIU Shaobo HUANG Xixian LI Zhongwu TAN Xiaofei ZENG Guangming ZHOU Lu | 2017 | Pedosphere2017，27，4： | 10 |
| 6 | Enhanced efficiency of cadmium removal by Boehmeria nivea(L.) Gaud. in the presence of exogenous citric and oxalic acids显示文摘Boehmeria nivea(L.)Gaud.is a potential candidate for the remediation of Cd contaminated sites.The present investigation aims to explore Cd tolerance threshold and to quickly identify the role of exogenous organic acids in Cd uptake and abiotic metal stress damage.Elevated Cd levels(0–10 mg/L)resulted in an obvious rise in Cd accumulation,ranging from268.0 to 374.4 in root and 25.2 to 41.2 mg/kg dry weight in shoot,respectively.Citric acid at1.5 mmol/L significantly facilitated Cd uptake by 26.7%in root and by 1-fold in shoot,respectively.Cd translocation efficiency from root to shoot was improved by a maximum of66.4%under 3 mmol/L of oxalic acid.Citric acid exhibited more prominent mitigating effect than oxalic acid due to its stronger ligand affinity for chelating with metal and avoiding the toxicity injury of free Cd ions more efficiently.The present work provides a potential strategy for efficient Cd remediation with B.nivea. | Huaying Li Yunguo Liu Guangming Zeng Lu Zhou Xin Wang Yaqin Wang Chunlin Wang Xinjiang Hu Weihua Xu | 2014 | Journal of Environmental Sciences2014，26，12： | 10 |
| 7 | Performance of biotrickling filters packed with structured or cubic polyurethane sponges for VOC removal显示文摘Two identical bench-scale biotrickling filters (BTFs),BTF 1 and BTF 2,were evaluated for toluene removal at various gas empty bed contact times (EBCTs) and organic loadings.BTF 1 and BTF 2 were packed with structured and cubic synthetic polyurethane sponges,respectively.At a constant toluene loading of 16 g/(m 3 ·hr),toluene removal efficiencies decreased from 98.8% to 64.3% for BTF 1 and from 98.4% to 74.1% for BTF 2 as gas EBCT decreased from 30 to 5 sec.When the toluene loading increased from 35 to 140 g/(m 3 ·hr) at a gas EBCT of 30 sec,the removal efficiencies decreased from 99.1% to 77.4% for BTF 1 and from 99.0% to 81.5% for BTF 2.The pressure drop for both BTFs increased with increased air flow rate,and did not significantly vary while the toluene loading was increased under similar operation conditions.BTF 1 and BTF 2 could start up successfully within 19 and 27 days,respectively,when packed with fresh sponge media,and the performances could be restored in 3-7 days after biomass was removed and wasted from the media.BTF 2 displayed higher removal efficiency even under shorter EBCT or higher loading rate than BTF1 when other operation conditions were similar,while it showed lower pressure drop than BTF 1 during the whole period of operation.These results demonstrated that both BTFs could treat waste gas containing toluene effectively. | Chunping Yang Guanlong Yu Guangming Zeng Haining Yang Fayuan Chen Congying Jin | 2011 | Journal of Environmental Sciences2011，23，8： | 10 |
| 8 | Effects of surfactants on enzyme-containing reversed micellar system显示文摘With the development of colloid interface and enzyme technologies,enzyme-containing reversed micellar system has been receiving much attention in bioseparation and bioconversion. Because of its high efficiency,it has brought new opportunities for the development of molecular biotechnology. Reversed micelles represent nano-sized aqueous droplets stabilized by surfactant amphiphiles inside the bulk organic solvents. The entrapped enzymes have enhanced activities under those conditions as suited in the lipid bilayers of biological membranes. The fundamentals of enzyme-containing reversed micellar system are described in this paper,with special emphasis on the effects of surfactants varying in concentrations and structures. The latest study progress on the surfactants application in enzyme-containing reversed micelles is reviewed. The introduction of novel functional surfactants in micellar enzymology and their future development are also discussed. | LIANG YunShan,YUAN XingZhong,ZENG GuangMing,ZHONG Hua,LI Hui & WANG WeiWei Key Laboratory of Environmental Biology and Pollution Control (Hunan University),Ministry of Education College of Environmental Science and Engineering,Hunan University,Changsha 410082,China | 2011 | Science China Chemistry2011，54，5： | 8 |
| 9 | Enhanced removal of ethylbenzene from gas streams in biotrickling filters by Tween-20 and Zn(Ⅱ)显示文摘The effects of Tween-20 and Zn(II)on ethylbenzene removal were evaluated using two biotrickling filters(BTFs),BTF1 and BTF2.Only BTF1 was fed with Tween-20 and Zn(II).Results show that ethylbenzene removal decreased from 94%to 69%for BTF1 and from 74%to 54%for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m3·hr)at EBRT of 40 sec.The effect of EBRT(60–15 sec)at a constant ethylbenzene inlet concentration was more significant than that of EBRT(30–10 sec)at a constant organic loading.Biomass accumulation rate within packing media was reduced significantly. | Lu Wang Chunping Yang Yan Cheng Jian Huang Haining Yang Guangming Zeng Li Lu Shanying He | 2014 | Journal of Environmental Sciences2014，26，12： | 8 |
| 10 | Biosorption of zinc(Ⅱ) from aqueous solution by dried activated sludge显示文摘The biosorption potential of dried activated sludge as a biosorbent for zinc(Ⅱ) removal from aqueous solution was investigated.The effects of initial pH,contact time,initial zinc ion concentration,and adsorbent dosage on the biosorption processes were determined,and the equilibrium data were modeled by the Langmuir and Freundlich isotherms.The Langmuir isotherm model (R 2=0.999) was proved to fit the equilibrium data much better than the Freundlich isotherm model (R 2=0.918).The monolayer adsorption capacity of dried activated sludge for zinc(Ⅱ) was found to be 17.86 mg/g at pH of 5 and 25°C.The kinetic data were tested using pseudo firstand second-order models.The results suggested that the pseudo second-order model (R 2 > 0.999) was better for the description of the adsorption behavior of zinc(Ⅱ) onto the dried activated sludge.Fourier transform infrared spectral analysis showed that the dominant mechanism of zinc(Ⅱ) biosorption onto the dried activated sludge was the binding between amide groups and zinc ions. | Chunping Yang Jiaqiang Wang Min Lei Gengxin Xie Guangming Zeng Shenglian Luo | 2010 | Journal of Environmental Sciences2010，22，5： | 6 |
| 11 | Shellac-coated iron oxide nanoparticles for removal of cadmium(Ⅱ) ions from aqueous solution显示文摘This study describes a new effective adsorbent for cadmium removal from aqueous solution synthesized by coating a shellac layer, a natural biodegradable and renewable resin with abundant hydroxyl and carboxylic groups, on the surface of iron oxide magnetic nanoparticles. Transmission Electron Microscopy (TEM) imaging showed shellac-coated magnetic nanoparticle (SCMN) adsorbents had a core-shell structure with a core of 20 nm and shell of 5 nm. Fourier Transform Infrared Spectroscopic analysis suggested the occurrence of reaction between carboxyl groups on the SCMN adsorbent surface and cadmium ions in aqueous solution. Kinetic data were well described by pseudo second-order model and adsorption isotherms were fitted with both Langmuir and Freundlich models with maximum adsorption capacity of 18.80 mg/g. SCMN adsorbents provided a favorable adsorption capacity under high salinity conditions, and cadmium could easily be desorbed using mild organic acid solutions at low concentration. | Jilai Gong Long Chen Guangming Zeng Fei Long Jiuhua Deng Qiuya Niu Xun He | 2012 | Journal of Environmental Sciences2012，24，7： | 5 |
| 12 | Three-Gorge Dam influences wetland macrophytes in middle and lower reaches of Yangtze显示文摘Dongting Lake,located in the middle and lower reaches of Yangtze,is regarded as a lake during the water swelling period and a continent in the ebbing period.The construction of the Three-Gorge Dam has influenced the water level of Dongting Lake and the growth of wetland macrophytes in the area.In this study,the growth of main species of wetland macrophytes,such as Carex and Phragmites at Dongting Lake,was observed,and the hydraulic gradient,one of the main factors dominating the abundance and distribution of wetland macrophytes,was also studied at six stations in Dongting Lake area and the effect of the Three-Gorge Dam construction on the growth of wetland macrophytes was observed. | Wang Lingling Zeng Guangming Li Zhongwu Su Xiaokang Li Jianbing Huang Guohe | 2007 | Progress in Natural Science:Materials International2007，17，9： | 4 |
| 13 | Adsorption of 17β-estradiol from aqueous solution by raw and direct/pre/post-KOH treated lotus seedpod biochar显示文摘Five biochars derived from lotus seedpod(LSP)were applied to examine and compare the adsorption capacity of 17β-estradiol(E2)from aqueous solution.The effect of KOH activation and the order of activation steps on material properties were discussed.The effect of contact time,initial concentration,p H,ionic strength and humic acid on E2 adsorption were investigated in a batch adsorption process.Experimental results demonstrated that the pseudo second-order model fitted the experimental data best and that adsorption equilibrium was reached within 20 hr.The efficiency of E2 removal increased with increasing E2 concentration and decreased with the increase of ionic strength.E2 adsorption on LSP-derived biochar(BCs)was influenced little by humic acid,and slightly affected by the solution p H when its value ranged from 4.0 to 9.0,but considerably affected at p H 10.0.Low environmental temperature is favorable for E2 adsorption.Chemisorption,π–πinteractions,monolayer adsorption and electrostatic interaction are the possible adsorption mechanisms.Comparative studies indicated that KOH activation and the order of activation steps had significant impacts on the material.Post-treated biochar exhibited better adsorption capacity for E2 than direct treated,pretreated,and raw LSP biochar.Pyrolyzed biochar at higher temperature improved E2 removal.The excellent performance of BCs in removing E2 suggested that BCs have potential in E2 treatment and that the biochar directly treated by KOH would be a good choice for the treatment of E2 in aqueous solution,with its advantages of good efficiency and simple technology. | Ni Liu Yunguo Liu Guangming Zeng Jilai Gong Xiaofei Tan Jun Wen Shaobo Liu Luhua Jiang Meifang Li Zhihong Yin | 2020 | Journal of Environmental Sciences2020，32，1： | 4 |
| 14 | Geochemistry of ore-forming fluids and geological significance of the Kuoerzhenkuola gold field in Xinjiang, China显示文摘The Kuoerzhenkuola gold field (including the Kuoerzhenkuola and the Buerkesidai gold deposits) is the most important one in the Sawuer gold belt, northern Xinjiang, China. Iso-topic studies including D, O, He, C, S, Pb and Sr reveal that the ore-forming fluids of the Kuo-erzhenkuola and the Buerkesidai deposits shared the same source: the water of ore fluids was magmatic water and minor meteoric water; the mineralizers and ore materials derived mainly from mantle beneath the island arc, and partially from crust. The ore-forming fluids of two depos-its are a mixture of mantle-derived fluids incorporated by crust-derived fluid, and meteoric water. Based on these results, combined with the consideration of the tectonic setting and geological features, we suggest that the two gold deposits in the Kuoerzhenkuola gold field, Sawur gold belt share the same genesis, and are volcanogenic hydrothermal gold deposits occurring in the same caldera. | SHEN Ping SHEN Yuanchao LIU Tiebing LI Guangming ZENG Qingdong | 2005 | Science China Earth Sciences2005，48，11： | 3 |
| 15 | Photodegradation of amoxicillin by catalyzed Fe^(3+)/H_2O_2 process显示文摘Three oxidation processes of UV-Fe3+(EDTA)/H2O2(UV:ultraviolet light;EDTA:ethylenediaminetetraacetic acid),UV-Fe3+/H2O2 and Fe3+/H2O2 were simultaneously investigated for the degradation of amoxicillin at pH 7.0.The results indicated that,100% amoxicillin degradation and 81.9% chemical oxygen demand(CODCr) removal could be achieved in the UV-Fe3+(EDTA)/H2O2 process.The treatment efficiency of amoxicillin and CODCr removal were found to decrease to 59.0% and 43.0% in the UV-Fe3+/H2O2 process;39.6% and 31.3% in the Fe3+/H2O2 process.Moreover,the results of biodegradability(biological oxygen demand(BOD5)/CODCr ratio) revealed that the UV-Fe3+(EDTA)/H2O2 process was a promising strategy to degrade amoxicillin as the biodegradability of the effuent was improved to 0.45,compared with the cases of UV-Fe3+/H2O2(0.25) and Fe3+/H2O2(0.10) processes.Therefore,it could be deduced that EDTA and UV light performed synergetic catalytic effect on the Fe3+/H2O2 process,enhancing the treatment efficiency.The degradation mechanisms were also investigated via UV-Vis spectra,and high performance liquid chromatography-mass spectra.The degradation pathway of amoxicillin was further proposed. | Xiaoming Li Tingting Shen Dongbo Wang Xiu Yue Xian Liu Qi Yang Jianbin Cao Wei Zheng Guangming Zeng | 2012 | Journal of Environmental Sciences2012，24，2： | 3 |
| 16 | Performance of rotating drum biofilter for volatile organic compound removal at high organic loading rates显示文摘不稳定的有机化合物(VOC ) 和生物资源的不平的分发,和在一些简历过滤器的过量生物资源累积妨碍简历过滤技术的申请。一个创新的多层的旋转鼓简历过滤器(RDB ) 被开发改正这些问题。RDB 在 30 s 的一空床接触时间(EBCT ) 和 1.0 r/min 的旋转的率被操作。Diethyl 醚被选择为模型 VOC。RDB 的性能以 32.1, 64.2, 128,和 256 g ether/(m3 · h ) 的器官的装载的率被评估(16.06 g ether/(m3 · h ) ≈ 1.0 kg 化学药品氧需求(货到付款)/(m3 · d )) 。EBCT 和器官的装载率根据中等体积被记录。结果证明醚移动效率与装载率的增加的 VOC 减少了。没有生物资源控制,超过 99% 的醚移动效率甚至在装载 128 g ether/(m3 · h ) 的率的高 VOC 被完成。然而,当装载率的 VOC 被增加到 256 g ether/(m3 · h ) 时,平均移动效率落下到 43% 。滋养的限制可能在醚移动效率贡献了落下。高生物资源累积率也在装载率的二更高的醚在媒介被观察,并且在媒介的过量生物资源的移动是必要的维持稳定的性能。这个工作证明 RDB 甚至以高器官的装载率在来自废气溪流的 diethyl 醚的移动是有效的。结果可能帮助为设计并且操作 RDB 建立标准。 | YANG Chunping CHEN Hong ZENG Guangming ZHU Xueqing SUIDAN Makram T | 2008 | Journal of Environmental Sciences2008，20，3： | 3 |
| 17 | Mechanism studies on nitrogen removal when treating ammonium-rich leachate by sequencing batch biofilm reactor显示文摘The nitrogen removal mechanism was studied and analyzed when treating the ammonium-rich landfill leachate by a set of sequencing batch biofilm reactors(SBBRs),which was designed independently.At the liquid temperature of(32P0.4)°C,and after a 58-days domestica-tion period and a 33-days stabilization period,the efficiency of ammonium removal in the SBBR went up to 95%.Highly frequent intermittent aeration suppressed the activity of nitratebacteria,and also eliminated the influence on the activity of anaerobic ammonium oxidation(ANAMMOX)bacteria and nitritebacteria.This influence was caused by the accumulation of nitrous acid and the undulation of pH.During the aeration stage,the concentration of dissolved oxygen was controlled at 1.2-1.4 mg/L.The nitritebacteria became dominant and nitrite accumulated gradually.During the anoxic stage,along with the concentration debasement of the dissolved oxygen,ANAMMOX bacteria became domi-nant;then,the nitrite that was accumulated in the aeration stage was wiped off with ammonium simultaneously. | XU Zhengyong YANG Zhaohui ZENG Guangming XIAO Yong DENG Jiuhua | 2007 | Frontiers of Environmental Science & Engineering2007，1，1： | 3 |
| 18 | Growth inhibition and oxidative damage of Microcystis aeruginosa induced by crude extract of Sagittaria trifolia tubers显示文摘Aquatic macrophytes are considered to be promising in controlling harmful cyanobacterial blooms. In this research, an aqueous extract of Sagittaria trifolia tubers was prepared to study its inhibitory effect on Microcystis aeruginosa in the laboratory. Several physiological indices of M. aeruginosa, in response to the environmental stress, were analyzed. Results showed that S. trifolia tuber aqueous extract significantly inhibited the growth of M. aeruginosa in a concentration-dependent way. The highest inhibition rate reached 90% after 6 day treatment. The Chlorophyll-a concentration of M. aeruginosa cells decreased from 343.1 to314.2 μg/L in the treatment group. The activities of superoxide dismutase and peroxidase and the content of reduced glutathione in M. aeruginosa cells initially increased as a response to the oxidative stress posed by S. trifolia tuber aqueous extract, but then decreased as time prolonged. The lipid peroxidation damage of the cyanobacterial cell membranes was reflected by the malondialdehyde level, which was notably higher in the treatment group compared with the controls. It was concluded that the oxidative damage of M. aeruginosa induced by S.trifolia tuber aqueous extract might be one of the mechanisms for the inhibitory effects. | Jiang Li Yunguo Liu Pingyang Zhang Guangming Zeng Xiaoxi Cai Shaobo Liu Yicheng Yin Xinjiang Hu Xi Hu Xiaofei Tan | 2016 | Journal of Environmental Sciences2016，28，5： | 3 |
| 19 | Biodegradation of 3,5-dimethyl-2,4-dichlorophenol in saline wastewater by newly isolated Penicillium sp.yz11-22N2显示文摘In this study,the performance of 3,5-dimethyl-2,4-dichlorophenol(DCMX) degradation by a screened strain was investigated.18 S r DNA and the neighbor-joining method were used for identification of the isolated strain.The results of phylogenetic analysis and scanning electron micrographs showed that the most probable identity of the screened strain should be Penicillium sp.Growth characteristics of Penicillium sp.and degradation processes of DCMX were examined.Fourier transform infrared spectroscopy of the inoculated DCMX solution was recorded,which supported the capacity of DCMX degradation by the screened Penicillium sp.Under different salinity conditions,the highest growth rate and removal efficiency for DCMX were obtained at p H 6.0.The removal efficiency decreased from 100%to 66% when the DCMX concentration increased from 5 to 60 mg/L,respectively.Using a Box–Behnken design,the maximum DCMX removal efficiency was determined to be 98.4%.With acclimation to salinity,higher removal efficiency could be achieved.The results demonstrate that the screened Penicillium sp.has the capability for degradation of DCMX. | Zhou Yan Huijun He Chunping Yang Guangming Zeng Le Luo Panpan Jiao Huiru Li Li Lu | 2017 | Journal of Environmental Sciences2017，29，7： | 3 |
