Interception storage adjustment system for intensively transferring initial rainwater by sewage interception pipe

Abstract

The invention discloses an interception storage adjustment system for intensively transferring initial rainwater by a sewage interception pipe. The interception storage adjustment system is arranged on multiple different confluence pipes and comprises an interception well arranged on each confluence pipe; the interception well is provided with a sewage interception pipe extending into a sewage plant, a water outlet communicated with a river channel, and a water inlet communicated with the confluence pipe; the storage adjusting system further comprises a storage adjustment pipe, an initial rainwater interception pipe and a filter layer arranged in the interception well; the filter layer is arranged between the water inlet and the water outlet so as to form a water inlet region adjacent to one side of the water inlet and a water outlet region close to one side of the water outlet in the interception well; one end of the initial rainwater interception pipe is communicated to the water outlet region; and the other end of the initial rainwater interception pipe is communicated into the storage adjustment pipe. According to the interception storage adjustment system, the interception effect is greatly improved, the intercepting dry weather flow is led into the sewage treatment plant, the rainwater is led into the storage adjustment pipe, the pollution of the river channel is reduced and the municipal drainage and storage adjustment capability is enhanced at the same time.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to an interception regulation and storage system for centralized transfer of primary rainwater by means of sewage interceptor pipes. Background technique [0002] With the development of industrial economy and the discharge of waste water in people's daily life, the rivers in many cities have been seriously polluted, and this phenomenon is common throughout 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 and implementable dry-flow sewage and initial rainwater interception and storage sy...
