摘要
根据大渡河流域中高山地区农村生活污水点多面广、污水来源分散、间隙性排放,且统一纳管进入城镇污水处理厂集中处理难度大的特点,本文以汉源县农村生活污水治理模式为例,考察了其污水处理设施处理效果,并对运维费用进行了分析。结果表明,本案例厌氧+芦苇湿地组合工艺能满足四川省地方标准《农村生活污水处理设施水污染物排放标准》(DB 51/2626-2019)一级标准要求,化学需氧量(COD_(Cr))、氨氮(NH_(3)-N)及总磷(TP)3种污染物去除率分别达到52.2%~79.6%、46.0%~79.2%、33.2%~84.9%,年运维费比有动力设施具有明显优势。本案例可为大渡河流域中高山区农村生活污水治理提供参考。
According to the characteristics of the wide range of rural domestic sewage points,scattered sewage sources,intermittent discharge,and the difficulty of centralized and unified collection into urban sewage treatment plants in the middle and high mountain areas of the Dadu River Basin,this paper takes the rural domestic sewage treatment model of Hanyuan as an example to investigate the treatment effects of its sewage treatment facilities and analyzes the operation and maintenance costs.The results show that the anaerobic+reed wetland combined process in this case can meet the first level standard requirements of the local standard Water Pollutant Discharge Standard for Rural Domestic Sewage Treatment Facilities(DB51/2626-2019)in Sichuan Province.The removal rates of chemical oxygen demand(COD_(Cr)),ammonia nitrogen(NH_(3)-N)and total phosphorus(TP)can reach 52.2%-79.6%,46.0%-79.2%and 33.2%-84.9%,respectively,and the annual operation and maintenance cost has a significant advantage compared to dynamic facilities.This case can provide reference for the treatment of rural domestic sewage in the middle-high mountain areas of the Dadu River Basin.
