摘　　要：针对南方典型山塘区农村散排污水未经处理直接入河引起水体水质恶化问题,因地制宜开发了基于给水污泥基质填料的山塘湿地生态治理技术,形成适于山塘区农村散排污水的强化化粪池—潮汐式给水污泥生态填料床—生物塘三级处理新工艺,并进行工程示范。现场试验表明,潮汐式给水污泥生态填料床对COD、氨氮、总氮、总磷的去除率分别为55.66%、87.02%、36.77%、91.62%,新工艺最终出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。综合经济分析,该工艺运行费用约为0.059 5万元/a,单位污水综合处理成本为0.4元/t,具有经济性、环境友好和可推广性。For water pollution caused by immediate discharge from rural decentralized sewage of a typical mountainous area in the south, an ecological treatment process was reasonably developed with water plant sludge as packing matrix. The new technology was a tertiary treatment which included an intensified septic tank,a packed bed of water plant sludge and a biological pond. It was suitable for scattered farmer＇s sewage in the mountainous area, and this technique was applied in the demonstration project. The field experimental results showed that the removal rates of the packed bed for COD, ammonia nitrogen,TN and TP were 55.66%, 87.02%,36.77% and 91.62%, respectively. And the water quality of final effluent water could meet the first criteria of A level of ＂Discharge standard of pollutants for municipal wastewater treatment plant＂ （GB 18918-2002）. Based on the analysis of technical economics, the running cost of the technology was as low as 595 yuan per year,and 0.4 yuan per ton of sewage. As a result,this technology had three properties of economy,environmental friendliness and generalizability.
