摘要
结合农村的实际情况,开发在太湖流域农村地区具有广泛推广价值的生活污水处理实用技术,并提出了应用多级土壤渗滤系统对集中型农村生活污水进行处理,且在江苏宜兴分水村建立了示范工程。结果表明,该系统基建及运行费用低,处理效果好,对COD、NH 4+-N、TN、TP和SS的平均去除率分别为70%、83%、59%、76%和94%;出水水质可达到《城镇污水处理厂污染物排放标准》的一级A标准。
By combining with the actual situation in the rural area,the practical technology of domestic wastewater treatment which had the wide popularization value in the rural area of Taihu Basin was developed.Moreover,the multi-soil-layering system was used to treat the concentrated rural domestic wastewater,and the demonstration project was established in Fenshui Village in Yixing,Jiangsu Province.The result showed that the cost of system infrastructure and operation was low,and the treatment effect was good.The average removal ratios of COD,NH＋4-N,TN,TP and SS were respectively 70%,83%,59%,76% and 94%.The quality of yielding water could reach Grade A standard of Pollutant Emission Standards in Urban Wastewater Treatment Plant.
