微生物燃料电池处理重金属废水的研究进展
Research advances in treatment of heavy metal wastewater by microbial fuel cells
摘要
Abstract
Based on the existing research basis, the mechanism of heavy metal removal involved in the special configuration and power generation conditions of microbial fuel cell (MFC) was analyzed. The effects of device configuration, cathode type, heavy metal concentration, external resistance, pH, electron acceptor type and other factors on MFC production performance and heavy metal removal efficiency were reviewed. From the aspects of bioelectrochemistry, microbial influence, and electron acceptor competition mechanism, the effects of single factors on heavy metal removal rate and reduction products were elucidated. It is proposed that the research on MFC removal of heavy metal wastewater in the future needs to be based on the actual wastewater and construct a pilot plant to provide data support for practical applications. Further, determine the primary and secondary status and direction of each influencing factor, and adjust the influencing factors according to the existing theoretical basis to obtain a faster removal rate and an ideal reduction product. At the same time, the electrode materials suitable for heavy metal separation are screened and the physical and chemical methods for product recovery can be investigated in order to realize the real recovery of heavy metals.关键词
