| 1 | Sulfur-based autotrophic denitrification from the micro-polluted water显示文摘Eutrophication caused by high concentrations of nutrients is a huge problem for many natural lakes and reservoirs. Removing the nitrogen contamination from the low C/N water body has become an urgent need. Autotrophic denitrification with the sulfur compound as electron donor was investigated in the biofilter reactors. Through the lab-scale experiment,it was found that different sulfur compounds and different carriers caused very different treatment performances. Thiosulfate was selected to be the best electron donor and ceramsite was chosen as the suitable carrier due to the good denitrification efficiency, low cost and the good resistibility against the high hydraulic loads. Later the optimum running parameters of the process were determined. Then the pilot-scale experiment was carried out with the real micro-polluted water from the West Lake, China. The results indicated that the autotrophic denitrification with thiosulfate as electron donor was feasible and applicable for the micro-polluted lake water. | Weili Zhou Xu Liu Xiaojing Dong Zheng Wang Ying Yuan Hui Wang Shengbing He | 2016 | Journal of Environmental Sciences2016，28，6： | 18 |
| 2 | Removal of anaerobic soluble microbial products in a biological activated carbon reactor显示文摘The soluble microbial products (SMP) in the biological treatment effluent are generally of great amount and are poorly biodegradable. Focusing on the biodegradation of anaerobic SMP, the biological activated carbon (BAC) was introduced into the anaerobic system. The experiments were conducted in two identical lab-scale up-flow anaerobic sludge blanket (UASB) reactors. The high strength organics were degraded in the first UASB reactor (UASB1) and the second UASB (UASB2, i.e., BAC) functioned as a polishing step to remove SMP produced in UASB1. The results showed that 90% of the SMP could be removed before granular activated carbon was saturated. After the saturation, the SMP removal decreased to 60% on the average. Analysis of granular activated carbon adsorption revealed that the main role of SMP removal in BAC reactor was biodegradation. A strain of SMP-degrading bacteria, which was found highly similar to Klebsiella sp., was isolated, enriched and inoculated back to the BAC reactor. When the influent chemical oxygen demand (COD) was 10,000 mg/L and the organic loading rate achieved 10 kg COD/(m 3 ·day), the effluent from the BAC reactor could meet the discharge standard without further treatment. Anaerobic BAC reactor inoculated with the isolated Klebsiella was proved to be an effective, cheap and easy technical treatment approach for the removal of SMP in the treatment of easily-degradable wastewater with COD lower than 10,000 mg/L. | Xiaojing Dong Weili Zhou Shengbing He | 2013 | Journal of Environmental Sciences2013，25，9： | 3 |
| 3 | Spatio-temporal Variation of Soil Respiration and Its Driving Factors in Semi-arid Regions of North China显示文摘Soil respiration(SR) is the second-largest flux in ecosystem carbon cycling. Due to the large spatio-temporal variability of environmental factors, SR varied among different vegetation types, thereby impeding accurate estimation of CO_2 emissions via SR. However, studies on spatio-temporal variation of SR are still scarce for semi-arid regions of North China. In this study, we conducted 12-month SR measurements in six land-use types, including two secondary forests(Populus tomentosa(PT) and Robinia pseudoacacia(RP)), three artificial plantations(Armeniaca sibirica(AS), Punica granatum(PG) and Ziziphus jujuba(ZJ)) and one natural grassland(GR), to quantify spatio-temporal variation of SR and distinguish its controlling factors. Results indicated that SR exhibited distinct seasonal patterns for the six sites. Soil respiration peaked in August 2012 and bottomed in April 2013. The temporal coefficient of variation(CV) of SR for the six sites ranged from 76.98% to 94.08%, while the spatial CV of SR ranged from 20.28% to 72.97% across the 12-month measurement. Soil temperature and soil moisture were the major controlling factors of temporal variation of SR in the six sites, while spatial variation in SR was mainly caused by the differences in soil total nitrogen(STN), soil organic carbon(SOC), net photosynthesis rate, and fine root biomass. Our results show that the annual average SR and Q_(10)(temperature sensitivity of soil respiration) values tended to decrease from secondary forests and grassland to plantations, indicating that the conversion of natural ecosystems to man-made ecosystems may reduce CO_2 emissions and SR temperature sensitivity. Due to the high spatio-temporal variation of SR in our study area, care should be taken when converting secondary forests and grassland to plantations from the point view of accurately quantifying CO_2 emissions via SR at regional scales. | ZENG Xinhua SONG Yigang ZHANG Wanjun HE Shengbing | 2018 | Chinese Geographical Science2018，28，1： | 3 |
| 4 | Use of zeolitized coal fly ash in the simultaneous removal of ammonium and phosphate from aqueous solution显示文摘Discharge of wastewater containing nitrogen and phosphate can cause eutrophication.Therefore,the development of an efficient material for the immobilization of the nutrients is important.In this study,a low calcium fly ash and high calcium fly ash were converted into zeolite using the hydrothermal method.The removal of ammonium and phosphate that coexist in aqueous solution by the synthesized zeolites were studied.The results showed that zeolitized fly ash could efficiently eliminate ammonium and phosphate at the same time.Saturation of zeolite with Ca^(2+)rather than Na+favored the removal of both ammonium and phosphate because the cation exchange reaction by the NH_(4)^(+)resulted in the release of Ca2+into the solution and precipitation of Ca^(2+)with PO_(4)^(3−)followed.An increase in the temperature elevated the immobilization of phosphate whereas it abated the removal of ammonium.Nearly 60%removal efficiency for ammonium was achieved in the neutral pH range from 5.5 to 10.5,while the increase or decrease in pH out of the neutral range lowered the adsorption.In contrast,the removal of phosphate approached 100%at a pH lower than 5.0 or higher than 9.0,and less phosphate was immobilized at neutral pH.However,there was still a narrow pH range from 9.0 to 10.5 favoring the removal of both ammonium and phosphate.It was concluded that the removal of ammonium was caused by cation exchange;the contribution of NH3 volatilization to immobilization at alkaline conditions(up to pH level of 11.4)was limited.With respect to phosphate immobilization,the mechanism was mainly the formation of precipitate as Ca_(3)(PO_(4))_(2) within the basic pH range or as FePO_(4) and AlPO_(4) within acidic pH range. | WU Deyi HU Zhanbo WANG Xinze HE Shengbing KONG Hainan | 2007 | Frontiers of Environmental Science & Engineering2007，1，2： | 2 |
| 5 | Variation of phytoplankton community before an induced cyanobacterial(Arthrospira platensis) bloom显示文摘A cyanobacterial (Arthrospira platensis) bloom was induced in situ by nutrient manipulation in an enclosure. The succession of the phytoplankton community and the water chemistry variations before the appearance of bloom, as well as their relationship, were investigated. The cell pigment variations were studied simultaneously. The Pearson's correlation analysis showed that there was no significant correlation between water chemistry and green algal or cyanobacterial composition, indicating that water chemistry variations were not suitable to be used as indicators for cyanobacterial-bloom early-warning. However, the diversity index of the phytoplankton community decreased sharply before the bloom appeared. Therefore, the dynamics of phytoplankton community was put forward to be an indicator for cyanobacterial-bloom early-warning. In addition, the cell pigment variations represented the changes of community structure, which should be useful for studying the dynamics of phytoplankton community. | WANG Chong, HUANG Yingying, HE Shengbing, LIN Yan, WANG Xinze, KONG Hainan School of Environmental Science and Engineering, Shanghai Jiao Tong University, Shanghai 200240, China. | 2009 | Journal of Environmental Sciences2009，21，12： | 2 |
