%X 本研究针对农村分散型生活污水特点及处理现状&#65292;结合AAO和人工湿地工艺设计制作一种农村生活污水一体化处理设备&#65292;并开展农村生活污水处理效果研究。结果表明&#65292;在无需外加碳源和化学药剂前提下&#65292;采用活性污泥法和人工湿地结合对污水中COD、氨氮和总氮去除效果较好&#65292;去除率分别为83%、87%和76%&#65292;对总磷的去除率相对较低&#65292;去除率为71%&#65292;出水水质基本可以达到GB18917-2002一级B标准。当进水污染物浓度一定范围增加时&#65292;设备对去除率相对稳定&#65292;具有较好的抗冲击负荷&#65292;为农村分散型生活污水处理提供技术支撑。<br>Considering the characteristics and treatment status of dispersed rural domestic sewage, this study combined AAO process and constructed wetland process to design an integrated equipment for rural domestic sewage treatment and tested its effect on. The results showed that the combined application of activated sludge method and constructed wetland had a good effect on domestic sewage treatment with the removal rate of COD, total nitrogen and ammonia nitrogen in sewage were 83%, 87% and 75% respectively without adding carbon sources and chemical. The removal rate of total phosphorus was relatively lower at 66%. The effluent quality can basically meet the GB18917-2002 Class B standard. When the concentration of influent pollutants increases in a certain range, the removal rate of the equipment for was relatively stable which indicated that the equipment has a good impact resistance load and provides support for rural dispersed domestic sewage treatment.
