区域污水系统客水排查实践研究

Study on practice of extraneous water investigation in a sewage system

以东部某城市区域污水系统为例,提出一种基于夜间自来水用量的快速客水排查方法,结合污水管网拓扑关系、用户调查、节点水质监测等情况,开展系统客水排查实践。结果表明,该方法能快速、高效地找出客水点,促进排水系统提质增效,并对其他地区污水系统的客水排查工作有较好的借鉴意义。

By taking the regional sewage system of an eastern city as the research object,a method based on tap water consumption at night to check extraneous water is proposed,which is combined with the topology sewage network,user surveys,node water quality monitoring,and other conditions.The results show that the method could quickly and efficiently identify the entry sites of extraneous water.It can promote the quality and efficiency of the drainage system,and provide a good reference for the extraneous water entry check in the sewage system of other areas.
