摘要:

工业废水中难降解污染物的强化去除是水处理的研究热点。介绍了生物电化学系统(BES)对废水中难降解污染物的降解原理,分析了电极、外加电压、盐度和电化学活性细菌(EAB)等因素对其处理效能的影响,讨论了其在偶氮染料废水、硝基芳烃废水、氯酚废水等典型难降解工业废水强化处理中的应用效果,并阐述了BES与生物法的耦合工艺及优势。分析认为BES中电极材料的经济性选择和改性修饰、EAB的筛选富集、实际应用电耗成本等是BES大规模应用亟待解决的问题。

Abstract:

The enhanced removal of refractory pollutants from industrial wastewater is a research hotspot in water treatment. This article introduced the principle of bioelectrochemical system(BES) degradation of pollutants in the treatment of refractory wastewater, and analyzed the effects of the factors such as electrodes, applied voltage, salinity, and electrochemically active bacteria(EAB) on the treatment efficiency, and discussed its application effect in the enhanced treatment of typical refractory industrial wastewater such as azo dyes wastewater, nitroaromatics wastewater, and chlorophenol wastewater. As well as the coupling process between BES and biomethods and its advantages were also described. It was considered that the economical selection and modification of electrode materials in BES, the enrichment of EAB screening, and the cost of practical power consumption were the issues that need to be resolved in large-scale applications of BES.

Key words: bioelectrochemical system(BES), refractory wastewater, electrode
