摘要
农村生活污水分散式治理是改善农村人居环境的重要手段。研究分析了南方某市农村生活污水设施工艺类型、建设造价等情况,结果表明:有动力设施数量占65%;无动力设施占35%;设计规模越大,设施的平均建设投资越低,配套管网的平均建设投资越高。当设计规模为10~300m^(3)/d,无动力设施平均投资成本为1.11~0.63万元/m^(3),管网平均投资成本为0.038~0.091万元/m;有动力设施平均投资成本为1.58~0.71万元/m^(3),管网平均投资成本为0.044~0.086万元/m。建议将邻近村庄串联,集中建设设施,增大管网的收集覆盖范围,提高污水收集处理率。
Decentralized treatment of rural domestic sewage was an important means to improve rural living environment.The technological types and construction cost of rural domestic sewage facilities in a city of south China were studied and analyzed.The results indicated that the number of powered facilities accounted for 65%and unpowered facilities accounted for 35%.The larger of the design scale resulted to the lower average facilities investment,and the larger average pipelines investment.When the design scale was 10-300 m^(3)/d,the average investment of unpowered facilities was 11100-6300 Yuan/m^(3),the pipelines investment was 380-910 Yuan/m;The average investment of powered facilities was 15800-7100 Yuan/m^(3),the pipelines investment was 440-860 Yuan/m.It is recommended to connect neighboring villages in series,build facilities in a centralized manner,increase the collection coverage of the pipe network,and increase the sewage collection and treatment rate.
