Design and operation effect of micro-power rural sewage treatment tactility

对浙江某微动力农村生活污水处理设施的设计与运行效果进行跟踪,结果表明:其对农村生活污水中SS,COD,TN,NH+4-N,TP等指标的去除率分别达到了89.3%,82.2%,58.2%,90.4%,56.1%,脱氮除磷效果较好,出水水质指标达到设计要求。该项目建设投资为64.8万元,投资成本为3240元/t,运行成本为0.71元/t。

This paper described the design and operation effect of micro-power sewage treatment in rural areas.The results showed that the removal rates of SS,COD,TN,NH+4-N and TP are 89.3%,82.2%,58.2%,90.4%and 56.1%.The effect of nitrogen and phosphorus removal gets better.In addition,and the effluent quality achieves the design demand.The investment of this project is 648,000 yuan,and the investment index of one ton is 3240 yuan,and the operating cost of one ton is 0.71 yuan.
