Separately-built type rainwater storage system

Abstract

The invention discloses a separately-built type rainwater regulation system, which is arranged on a plurality of different confluence tubes. The regulation system comprises a first interception well, a second interception well, a regulation tube, and filter layers which are arranged in the first interception well and the second interception well respectively; the first interception well is provided with a sewage interception tube which extends to a sewage plant, a drainage port connected with a river channel, and an end water inlet connected with the end parts of the confluence tubes; and the second interception well is provided with an initial rain interception tube which extends to the regulation tube, and a side water inlet connected with the side parts of the confluence tubes. The separately-built type rainwater regulation system disclosed by the invention is suitable for the current situation as well as still convenient and realizable in case of an insufficient site; simultaneously, the interception effect can be greatly improved, and the intercepted drought flow sewage is intercepted in the sewage treatment plant and rainwater is intercepted in the regulation tube, so as to reduce pollution on the river channel, and improve the regulation capacity of urban drainage.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to a separate rainwater regulation and storage system. 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. Especially in the case of insufficient current sites, how to ensure the implementation of sewage interception structures, solve the problem of polluting river channels, and ensure the normal function of pipeline network operation and river flood c...
