摘　　要：针对广西某农村生活污水特点及当地经济状况,采用太阳能微动力AO+HPQ生态水培槽与生态滤池的组合工艺处理农村生活污水。设计开发的HPQ生态水培槽分成微曝气厌氧/好氧生化反应层和组合填料水培槽两层,自动控制间歇微曝供氧和循环操控运行,能灵活调节对有机污染物,尤其是氮磷的去除效率。经组合工艺处理后,对COD去除率为80%,对氨氮去除率为93%,对总磷去除率为83%,出水水质满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B标准。同时,系统采用光伏发电为处理系统提供微动力,有效地降低了处理系统的能耗和运行成本,主要运行管理费用为兼职人员人工费。Aiming at local sewage characteristics and economic conditions in a rural area of Guangxi,a combined process of solar micro-power AO,HPQ ecological hydroponic tank and ecological filter was used to treat the rural domestic sewage. The HPQ ecological hydroponic tank was divided into two layers including the micro-aerated anaerobic/aerobic biochemical reaction layer and the combined filler hydroponic tank layer. The automatic control of intermittent micro-exposure oxygen supply and cyclic control operation could flexibly adjust the efficiency for organic pollutants,especially nitrogen and phosphorus removal. After the combined process treatment,the average removal rates of COD,NH3-N and TP were 80%,93% and 83%,respectively,which could meet the requirement of the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). At the same time,micro-power was provided by photovoltaic power generation,which effectively reduced energy consumption and operating cost of the processing system. The main operation and management costs were part-time personnel management.
