在传统排水体制的基础上,分析了城市排水体制在实际运行中存在的问题,提出了截流式分流制和溢流污水处理——截流式合流制两种新型的排水体制,介绍了两种新型排水系统的工作原理、设计参数等,以期为新建城区的管网建设和老城区的管网改造提供借鉴。 Based on the traditional drainage system, this paper analyzes the problems existing in the actual operation of the urban drainage system, and proposes two new types of drainage systems, namely, the intercepting and diversion system and the intercepting and merging wastewater treatment system. Two new types of drainage systems are introduced Drainage system works, design parameters, etc., with a view to the construction of new urban pipe network construction and old city pipe network to provide reference.
