随着城镇污水处理厂（WWTP）建成与投入使用数量的增加和污水排放标准的日趋严格，剩余污泥的稳定化处理和二级处理出水的深度处理备受关注。本项目以剩余污泥有机物与二级处理出水中难降解污染物为对象，创新性地提出构建高效、绿色与低耗的微生物电化学耦合芬顿系统（MES-F）对两者进行同步处理。首先通过对反应器构型、电极材料、底物调节剂的筛选，构建高效的MES-F系统；其次通过对MES-F系统功率密度、污泥稳定化程度及脱水性能、污染物浓度等的测试，考查该系统同步降解污染物的效能；然后通过考查污泥有机物与二级处理水中难降解有机物等降解历程，阐释MES-F系统对各污染物降解的转化途径；最后通过深度解析MES-F系统各界面的联动反应，揭示该系统阳极室界面、阴极室界面、电子产生传递及利用的界面反应机制。研究成果可为剩余污泥的稳定化与无害化处理、WWTP二级处理出水的深度处理提供一种新的工艺方法与理论依据。

With more constructions and applications of wastewater treatment plants (WWTPs) and much stringent criteria of wastewater treatment plants (WWTPs) discharge standard, the stabilization of excess sludge and the advanced treatment of secondary effluent have been becoming the research hotspot and focus both home and abroad. Aiming at the simultaneous treatment of organics in excess sludge and refractory pollutants in secondary effluent, an efficient, environmental friendly and energy-saving microbial electrochemical system coupling Fenton (MES-F) process was proposed creatively to achieve the synchronous treatment of two pollutants. First, MES-F process will be constructed by choosing suitable reactor configuration, electrode material and substrate modifier. Secondly, by measuring such parameters as electricity power density, sludge stabilization degree, sludge dewaterability and pollutant concentration, the synchronous pollutant removal performance in the MES-F system will be investigated. Thirdly, by analyzing the degradation steps of sludge organics and refractory pollutants in secondary effluent, the pollutant degradation pathway in MES-F system will be elucidated. Lastly, by in-depth analyses of the interaction of multi-interfaces in MES-F system, the reaction mechanisms of anodic chamber interface, cathodic chamber interface, electron transfer and utilization interfaces will be revealed. The obtained results of this project will provide a brand new technique and theory support for the stabilization and harmless disposal of excess sludge and the advanced treatment of WWTP secondary effluent.
