【摘要】：微生物电化学技术(Microbial Electrochemical Technology,MET)作为一种新型水处理工艺,由于具有污染物同步去除和能源化的特点受到广泛重视.近年来,微生物电化学系统(Microbial Electrochemical System,MES)的研究者在其电子传递机理、功能菌群分析、系统功能拓展、低成本材料开发和大型系统构建等方面取得大量进展.然而,该技术作为污水处理工艺的可行性却始终存在争议.本文从应用角度将MET工艺与现有厌氧、好氧工艺进行对比,分析各工艺在有机物降解和能量回收方面的特点,有助于找到MET工艺在水处理领域中的适宜定位.相对厌氧与好氧工艺,MET工艺具有低污泥产率、运行过程能量自给以及电流加速污染物去除等优势特征,但在推进MET工艺的实用化进程中仍需进一步简化其系统结构、降低构筑成本、提高运行稳定性,并应基于MET的运行特征确定其适宜的应用范围以发挥MET工艺的技术优势.
[Abstract]:Microbial Electrochemical Technology (met), as a new water treatment process, has attracted much attention due to its characteristics of simultaneous removal of pollutants and energy conversion.In recent years, researchers of microbial Electrochemical system have made great progress in their electronic transport mechanism, functional microflora analysis, system functional expansion, low-cost material development and large-scale system construction.However, the feasibility of the technology as a sewage treatment process has always been controversial.This paper compares the MET process with the existing anaerobic and aerobic processes from the application point of view, analyzes the characteristics of each process in organic matter degradation and energy recovery, which is helpful to find the suitable location of the MET process in the field of water treatment.Compared with the anaerobic and aerobic process, met process has the advantages of low sludge yield, energy self-sufficiency during operation, and current accelerated pollutant removal. However, it is still necessary to further simplify the system structure in the process of practical application of MET process.It is necessary to reduce the construction cost and improve the operation stability, and the suitable application scope should be determined based on the operation characteristics of MET in order to give full play to the technical advantages of MET process.
