摘 要：Abstract：The invention belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment device and a sewage treatment method for a self-cleaning type micro-aeration vertical baffled wetland. The invention discloses the sewage treatment device for the self-cleaning type micro-aeration vertical baffled wetland. The sewage treatment device consists of a water distribution region, a tank body and a water collecting region; to-be-treated sewage flows into the water distribution region through a water inlet tube, and then flows from the distribution region into the tank body by taking an overflow; outlet water treated by the tank body flows into the water collecting region by taking an overflow; and the tank body is formed by connecting a plurality of stages of vertical baffled wetlands with different treatment functions in series, in a water flow direction, namely an anaerobic wetland, a carbon oxidization wetland and a short-cut nitrification-denitrification wetland. The invention further provides a sewage treatment method by adopting the device. According to the device provided by the invention, the tank body is divided into an anaerobic section, an aerobic section and a micro-aerobic section in the water flow direction, and efficient removal of carbon pollutants and nitrogen pollutants can be realized; and the problems that a conventional constructed wetland is too low in dissolved oxygen, relatively great in land area, easy to block by stuffing and difficult to clean after being blocked are solved.
主 权 项：自清式微曝气竖向折流湿地污水处理装置，其特征在于：由配水区、池体和集水区组成；待处理污水经进水管流入配水区，再通过溢流的方式从配水区流入池体，经池体处理后的出水采用溢流的方式流入集水区；所述池体为多级不同处理功能的竖向折流湿地串联而成，沿水流方向依次为厌氧湿地、碳氧化湿地和短程硝化?反硝化湿地，厌氧湿地和碳氧化湿地各采用一个单元池，短程硝化?反硝化湿地由若干单元池组成；厌氧湿地从底部往上依次设置有反冲洗管和填料层；碳氧化湿地和短程硝化?反硝化湿地从底部往上依次设置有反冲洗管、微曝气管、填料层和水生植物，采用分级微曝气方式，总的曝气量的气水比小于2︰1，并控制碳氧化湿地的曝气量大于短程硝化?反硝化湿地，使碳氧化湿地中水的溶解氧达到1～2MG/L，短程硝化?反硝化湿地水中的溶解氧达到0.5MG/L。
