Discussion on Rural Domestic Sewage Treatment Project in Xinxiang County

对河南省新乡县各乡镇的用水现状进行了调查,对这些地方的污水(包括生活污水和养殖废水)总量进行了预测,折污系数取0.7,污水管网收集率取90%。根据新乡县地形地势,结合当地现有污水处理设施的情况及污水收集模式,将该县县域农村污水系统划分为12个部分。介绍了新乡县各乡镇污水处理工程建设现状,对其污水处理程度、污水处理工艺、污泥处理进行了探讨。最后,就污水处理工程如何更好地运行维护管理提出了建议。

Xinxiang County is located in the central part of Henan Province,with five transit rivers.Due to the disorderly discharge of domestic sewage and aquaculture wastewater from existing houses on both sides of the line,the water environment in the county is poor.Through the investigation of current rural water use,the sewage conversion coefficient is taken as0.7 and the collection rate of sewage pipe network is taken as 90%.According to the terrain,combined with the current sewage treatment facilities and collection mode in the county,the rural sewage system in Xinxiang County is divided into 12sewage systems.According to the construction status of sewage projects in villages and towns in Xinxiang County,the degree of sewage treatment,sewage treatment process and sludge treatment are discussed.Finally,suggestions and countermeasures are put forward on how to better operate and manage the sewage treatment project.
