Sewage pipe network is the key of sewage collection and centralized processing.Although most cities are all built with a sewage treatment plant,due to economic conditions,management way to restrict,and the lag of supporting for sewage collection pipe network,sewage access departments and the pipe construction could not realize synchronization,causing the low rate of sewage collection.Nowadays,there are a large number of sewage pipe network under construction,and we have to think about the related problems in its management.%污水管网是污水收集和集中处理的关键,大多数城市均建有污水处理厂,由于受城市建设、经济条件和管理方式的制约,配套活污水收集管网及泵站建设相对滞后,污水接入单位没有与污水干管建设实现同步,致使污水收集率偏低。目前存在大量污水管网的改造建设,其管理中存在的问题是我们必须面对和思考的。
