Dry weather flow and initial rainwater multifunctional catch basin for combined network

Abstract

The invention discloses a dry weather flow and initial rainwater multifunctional catch basin for a combined network. The dry weather flow and initial rainwater multifunctional catch basin for the combined network comprises a basin body. The basin body is provided with an interceptor sewer extending to a sewage plant, an initial rainwater interceptor extending to a regulation and storage pipe, a water outlet communicated with a river channel, and a water inlet communicated with a combining pipe. The catch basin further comprises a filter layer disposed in the basin body. The filter layer is disposed between the water inlet and the water outlet so that a water inlet area close to one side of the water inlet and a water outlet area close to one side of the water outlet form in the basin body. The filter layer comprises a stop board disposed on the upper portion of the basin body, an overflow weir disposed on the lower portion of the basin body and a filter net disposed between the stop board and the overflow weir. The stop board is provided with through holes. The dry weather flow and initial rainwater multifunctional catch basin for the combined network has the advantages that the multifunctional catch basin is convenient to implement, the filter layer can be cleaned automatically, intercepting effect is improved, service life of the catch basin is prolonged, and river channel pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to a multi-functional interception well for dry flow sewage and initial rainwater of a confluence pipe network. Background technique [0002] With the development of the industrial economy and the discharge of waste water in people's daily life, the rivers in many cities have been seriously polluted, and the problem of waterlogging in cities has become increasingly serious. This problem is universal across the country. [0003] In order to prevent river pollution, it is necessary to collect initial rainwater and dry sewage. The common method is to intercept the sewage before draining into the river. However, due to the limited capacity of the interception pipeline along the coast, overflow is likely to occur in rainy days, which seriously pollutes the river. [0004] Therefore, those skilled in the art are committed to developing a convenient, implementable, and self-cleaning...
