Biomembrane electrode coupled constructed wetland reactor and sewage treatment method thereof

The invention discloses a biomembrane electrode coupled constructed wetland reactor and a sewage treatment method thereof. The biomembrane electrode coupled constructed wetland reactor is characterized in that sewage is treated by using adding graphite to the upper layer of constructed wetland to form an anode and adding a steel wire mesh and active carbon to the anaerobic environment of the lowerlayer of the constructed wetland to form a composite cathode, and a certain micro-current is introduced to enhance nitrogen removal of the reactor and improve the microcystin removal efficiency. Thereactor has the advantages of simple device, convenience in operation and management, good treatment effect, small occupied area, and significant improvement of the treatment effect on the sewage containing nitrogen and microcystins. 本发明公开了一种生物膜电极耦合人工湿地反应器及其污水处理方法，采用生物膜电极耦合人工湿地反应器以人工湿地上层加以石墨为阳极，下层厌氧环境加入钢丝网和活性炭作为复合阴极对污水进行处理，通过引入一定的微电流能加强反应器的脱氮和微囊藻毒素去除效率。本发明装置简单、运行管理方便、处理效果良好且占地面积小，可以显著提高对含氮和微囊藻毒素污水的处理效果。
