摘　　要：文章针对农村污水重力排水收集系统存在的施工空间小、施工困难,矛盾多等诸多问题,在南通市海安市大公镇于坝村采用单相流负压排水系统,284户农户生活污水进行收集,优化了于坝村污水收集模式,确定了单相流负压排水系统的设计方案,并在工程施工难度、施工周期、运行效果等方面与重力排水系统进行了比较。研究结果表明,单相流负压排水系统优势较为明显,可以有效降低施工难度,缩短施工周期,提高农村污水收集率,在河网密集的农村地区具有良好的应用推广价值。In view of the problems existing in the rural sewage gravity drainage collection system,a single-phase flow negative pressure drainage system is adopted in Yuba village,Dagong town,Haian city,Nantong city,which overcomes the problems of small construction space,difficult construction,and many contradictions,and optimizes the sewage collection mode of Yuba village.The domestic sewage of 284 rural households in Haian city,Nantong city was collected by single-phase flow negative pressure drainage system,and the design scheme of single-phase flow negative pressure drainage system was determined,and the gravity drainage system was compared with the gravity drainage system in terms of construction difficulty,construction period and operation effect.The research results show that the advantages of single-phase flow negative pressure drainage system are more obvious,which can effectively reduce the difficulty of construction,shorten the construction cycle,improve the rural sewage collection rate,and have good application and promotion value in rural areas with dense river network.
