| 摘 要： | 电-生物耦合技术是一种结合生物法和电化学法优势的新型水处理技术。目前研究主要集中在:利用阴极产氢作为电子供体实现硝酸盐废水脱氮;利用阳极产氧阴极产氢实现同步硝化反硝化作用进而使氨氮直接转化为氮气;利用阴极还原脱毒实现有毒有机废水的降解;利用微电场改变细胞膜通透性或促进酶的活性强化废水处理效果。本文在分析了各种电-生物耦合技术应用原理的基础上,综述其应用现状与存在的不足,并对该技术的继续深入研究作出了展望。

| Abstract: | Bio-electrochemical technology is a novel one for wastewater treatment,combining electrochemical and biological methods.Diverse applications were reported to:(1) nitrogen removal in nitrate wastewater using the cathode to generate hydrogen as electron donor;(2) the simultaneous nitrification and denitrification system-producing utilizing the anode to generate oxygen while the cathode to hydrogen,which transfer the ammonia into nitrogen directly;(3) pollutant-degradation in organic toxic wastewater using the reduction system in cathode;(4) degrading-efficiency improvement employing the micro-electric field to promote the permeability of cell membrane or the activities of metabolic enzymes.Base on the analysis of each kind of mechanism in 4-aspect application,we summarized its advantages and disadvantages of the bio-electrochemical technology.In addition,the prospect of the future research was presented. |
