【摘要】：微生物電化學(xué)技術(shù)(Microbial Electrochemical Technology,MET)作為一種新型水處理工藝,由于具有污染物同步去除和能源化的特點(diǎn)受到廣泛重視.近年來(lái),微生物電化學(xué)系統(tǒng)(Microbial Electrochemical System,MES)的研究者在其電子傳遞機(jī)理、功能菌群分析、系統(tǒng)功能拓展、低成本材料開(kāi)發(fā)和大型系統(tǒng)構(gòu)建等方面取得大量進(jìn)展.然而,該技術(shù)作為污水處理工藝的可行性卻始終存在爭(zhēng)議.本文從應(yīng)用角度將MET工藝與現(xiàn)有厭氧、好氧工藝進(jìn)行對(duì)比,分析各工藝在有機(jī)物降解和能量回收方面的特點(diǎn),有助于找到MET工藝在水處理領(lǐng)域中的適宜定位.相對(duì)厭氧與好氧工藝,MET工藝具有低污泥產(chǎn)率、運(yùn)行過(guò)程能量自給以及電流加速污染物去除等優(yōu)勢(shì)特征,但在推進(jìn)MET工藝的實(shí)用化進(jìn)程中仍需進(jìn)一步簡(jiǎn)化其系統(tǒng)結(jié)構(gòu)、降低構(gòu)筑成本、提高運(yùn)行穩(wěn)定性,并應(yīng)基于MET的運(yùn)行特征確定其適宜的應(yīng)用范圍以發(fā)揮MET工藝的技術(shù)優(yōu)勢(shì).
[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.
