Background
The existing urban drainage pipe network in China is 68.3 kilometers, wherein the proportion of the combined system pipe network is more than 20%, and because the design and construction of the urban drainage pipe network in China in the past are basically continued by the Soviet Union method, the traditional centralized urban drainage system improves the water environment, and simultaneously highlights the problem of hydraulic load impact of the concentrated pipe network system on the rapid collection and rapid drainage of rainwater in a catchment area in rainy season, which causes the large increase of short-term water inflow of a sewage plant. Most of the existing sewage treatment processes in China are activated sludge process systems, and the problem that the treatment processes and the operation modes cannot deal with peak flow in rainy seasons exists in many times, so that the pipe network overflows along the way or overflows in front of the sewage treatment plant or exceeds the peak flow in rainy seasons, and urban rivers and receiving water bodies are seriously polluted.
Although many modern towns are transformed in recent years, the problems of throwing away the sewage from the reconstruction process of the combined system drainage system exist, the traditional combined system pipe network has the conditions of long-term rain and sewage mixed flow, pollutant overflow and drainage, urban waterlogging caused by unsmooth drainage, and the functional defects of small exposed cut-off multiple, lack of perfect sewage cut-off facilities and the like. In the reconstruction and expansion process, the conditions of a plurality of urban pipe networks are complex, a plurality of pipe network construction modes coexist, for example, closure type flow-combining mode exists, the newly reconstructed flow-dividing pipe network has the defects of incomplete closure of initial rainwater degree with high pollution degree, and incomplete flow division caused by mixed connection and misconnection of pipelines. Various pipe networks actually have the functional defects of lack of reasonable pollutant interception means, small interception multiple, unsmooth drainage and the like, and the phenomena of pollutant overflow and river drainage, rainwater entering sewage plants, urban inland inundation, sewage overflow and the like are frequently shown in a centralized manner.
