摘要
对绍兴柯桥区14个建制镇138个村的374座农村生活污水终端的处理能力、处理工艺和出水排放标准等进行统计分析,结果表明57.2%的农村生活污水终端处理能力低于30 m^(3)/d,主要为生物处理工艺,组合工艺较少,出水标准主要按照《农村生活污水处理设施水污染物排放标准》执行。对柯桥区每个建制镇中选取一个运行稳定的农村生活污水终端,分别采用模糊优劣系数法和基于熵权指数的模糊物元模型方法对14个农村生活污水终端工艺进行综合评价和分析,结果表明漓渚镇所选用的AO—人工湿地的方法更适合该地区的农村生活污水的处理。
This paper makes a statistical analysis of the treatment capacity,treatment process and effluent discharge standards of 374 rural domestic sewage terminals in 138 villages of 14 established towns in Keqiao District.The results show that 57.2%of rural domestic sewage terminal treatment capacity is less than 30 m^(3)/d.It is mainly a biological treatment process with few combined processes,and the effluent standards are mainly implemented in accordance with the Discharge standards for water pollutants in rural domestic sewage treatment facilities.For each of the established towns in Keqiao district,a rural sewage terminal with stable operation was selected,and the fuzzy merit method and the fuzzy matter-element model method based on entropy weight index were used to comprehensively evaluate and analyze the 14 rural sewage terminal technologies.The results show that the AO-constructed wetland method selected in Lizhu Town is more suitable for the treatment of rural domestic sewage in this area.
