| 1 | Comparison and modeling of two biofilm processes applied to decentralized wastewater treatment显示文摘In order to control water pollution in the rapidly urbanizing South China area,biological contact oxidation(BCO)process and biological aerated filter(BAF)process were applied in a pilot-scale experiment for decentralized wastewater treatment.An investigation to find the optimal parameters of the two biofilm systems was conducted on hydraulic loading,organic loading,and aeration rate.The results indicated that the water reuse criteria required a maximum hydraulic and organic loading of 30.0 m^(3)/(m^(2)·d)and 4.0 kg COD/(m^(3)·d),respectively,as well as a minimum effluent DO of 4.0 mg/L.The utilization of a new media allowed BAF to perform better than BCO.The kinetic description of the COD removal process for BAF and BCO are Se=S0e^(-0.639t)/(1+1.035t),and S_(e)=S_(0)/[(1+0.947t)(1+1.242t)],respectively.The correlativity analysis showed that the two models could predict the effluent water quality based on the hydraulic retention time.Thus,the appropriate hydraulic loading for certain effluent water quality demands could be determined.The two models could be applied to wastewater treatment practice. | Guanglei QIU Liancheng XIANG Yonghui SONG Jianfeng PENG Ping ZENG Peng YUAN | 2009 | Frontiers of Environmental Science & Engineering2009，3，4： | 4 |
| 2 | An Endotenon Sheath-Inspired Double-Network Binder Enables Superior Cycling Performance of Silicon Electrodes显示文摘Silicon(Si)has been regarded as an alternative anode material to traditional graphite owing to its higher theoretical capacity(4200 vs.372 m Ah g;).However,Si anodes suffer from the inherent volume expansion and unstable solid electrolyte interphase,thus experiencing fast capacity decay,which hinders their commercial application.To address this,herein,an endotenon sheathinspired water-soluble double-network binder(DNB)is presented for resolving the bottleneck of Si anodes.The as-developed binder shows excellent adhesion,high mechanical properties,and a considerable self-healing capability mainly benefited by its supramolecular hybrid network.Apart from these advantages,this binder also induces a Li;N/Li F-rich solid electrolyte interface layer,contributing to a superior cycle stability of Si electrodes.As expected,the DNB can achieve mechanically more stable Si electrodes than traditional polyacrylic acid and pectin binders.As a result,DNB delivers superior electrochemical performance ofSi/Li half cells and Li Ni;Co;Mn;O;/Si full cells,even with a high loading of Si electrode,to traditional polyacrylic acid and pectin binders.The bioinspired binder design provides a promising route to achieve long-life Si anode-assembled lithium batteries. | Meifang Jiang Pengzhou Mu Huanrui Zhang Tiantian Dong Ben Tang Huayu Qiu Zhou Chen Guanglei Cui | 2022 | Nano-Micro Letters2022，14，6： | 2 |

| 9 | Biotoxicity evaluation of zinc oxide nanoparticles on bacterial performance of activated sludge at COD,nitrogen,and phosphorus reduction显示文摘The unique properties and growing usage of zinc oxide nanoparticles increase their release in municipal wastewater treatment plants.Therefore,these nanoparticles,by interacting with microorganisms,can fail the suitable functioning of biological systems in treatment plants.For this reason,research into the toxicity of ZnO is urgent.In the present study,the toxicity mechanism of ZnO-NPs towards microbial communities central to granular activated sludge(GAS)performance was assessed over 120-day exposure.The results demonstrate that the biotoxicity of ZnO-NPs is dependent upon its dosage,exposure time,and the extent of reactive oxygen species(ROS)production.Furthermore,GAS performance and the extracellular polymeric substances(EPS)content were significantly reduced at 50 mg/L ZnO-NPs.This exposure led to decreases in the activity of ammonia monooxygenase(25.2%)and nitrate reductase(11.9%)activity.The Field emission scanning electron microscopy images confirmed that ZnO-NPs were able to disrupt the cell membrane integrity and lead to cell/bacterial death via intracellular ROS generation which was confirmed by the Confocal Laser Scanning Microscopy analysis.After exposure to the NPs,the bacterial community composition shifted to one dominated by Gram-positive bacteria.The results of this study could help to develop environmental standards and regulations for NPs applications and emissions. | Hasti Daraei Kimia Toolabian Ian Thompson Guanglei Qiu | 2022 | Frontiers of Environmental Science & Engineering2022，16，2： | 0 |

| 11 | Anti-corrosive Hybrid Electrolytes for Rechargeable Aqueous Zinc Batteries显示文摘Aqueous zinc(Zn)-metal cells with cost-effective components and high safety have long been a promising large-scale energy storage system,but Zn anodes are intrinsically unstable with common aqueous electrolytes,causing substantial underutilization of the theoretical capacity.In this work,we report a strictly neutral aqueous Zn electrolyte at a low cost by leveraging the dynamic hydrolysis equilibrium of a dual-salt Zn(Ac)2/NaAc(Ac:CH3COO−)formulation.With the pH regulation,the corrosion and hydrogen evolution encountered in Zn anodes can be suppressed significantly.This hybrid aqueous electrolyte not only enables dendrite-free Zn plating/stripping at a nearly 95%Coulombic efficiency[an increase of 24%compared to that of the single-salt 1 mol/L Zn(Ac)2 electrolyte],but also supports the reversible operation of Zn cells paired with either Na3V2(PO4)3 or iodine cathodes—the former delivers a high output voltage of 1.55 V with an energy level of 99.5 W·h/kg(based on the mass of the cathode),and the latter possesses a high specific capacity of 110.9 mA·h/g while yielding long-term cyclability(thousands of cycles).These findings open up a new avenue of modifying practical electrolytes having targeted properties to stabilize multivalent metal anodes. | WANG Jia QIU Huayu ZHAO Zhiming ZHANG Yuchen ZHAO Jingwen MA Yinglei LI Jiedong XING Min LI Guicun CUI Guanglei | 2021 | Chemical Research in Chinese Universities2021，37，2： | 0 |
