Intercepting system and intercepting method

Abstract

The invention relates to the technical field of water conservancy projects, in particular to an intercepting system and an intercepting method. The intercepting system comprises an intercepting well, a filtering assembly, a water conveying device and a cleaning device; the intercepting well is provided with a first inflow opening, a first outflow opening and a second outflow opening, the first inflow opening is configured to communicate with a confluence pipeline, the first outflow opening is configured to communicate with a sewage pipeline, and the second outflow opening is configured to communicated with a rainwater pipeline; the filtering assembly is further configured to filter sewage in the intercepting well, and water filtered by the filtering assembly flows into the rainwater pipeline; one end of the water conveying device communicates with a water collecting pipe of the filtering assembly, and the other end of the water conveying device is configured to communicate with the rainwater pipeline; and the cleaning device is configured to clean the filtering assembly. The problem of urban inland inundation caused by overflow sewage or water quality deterioration caused by direct discharge of the overflow sewage into environmental water is solved to a certain extent.

Description

technical field [0001] The present disclosure relates to the technical field of water conservancy engineering, in particular to a closure system and a closure method. Background technique [0002] Based on the status quo of urban drainage in my country, both combined and diverted systems will continue to exist. The overflow pollution of combined pipe network in rainy season and the control of rainwater pollution in the early stage of separate system are the most difficult points in the upgrading and transformation of drainage pipe network. As the core structure, interception wells are widely used in projects such as mixed flow mouth renovation and rainwater runoff interception. During the rainy season, when the sewage pipeline downstream of the interception well is running at full capacity, the sewage in the interception well cannot be effectively intercepted and transported, and the overflow sewage will cause urban waterlogging or be directly discharged into the environment...

AI Technical Summary

Problems solved by technology

[0003] The present disclosure provides an interception system and an interception method to solve the problem realized by the inventor that during the rainy season, when the sewage pipeline downstream of the interception well runs at full capacity, the sewage in the interception well cannot be effectively intercepted and transported, and the overflow sewage will cause urban waterlogging or direct discharge into environmental water bodies leading to technical problems of water quality deterioration
