Embodiment Construction

[0029] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0030] Embodiments of the present invention provide a municipal rain and sewage diversion device, such as figure 1 and figure 2 As shown, it includes a pool body, a cover plate, a partition wall and a diversion tank 13 with an opening 135. The cover plate is arranged on the top of the pool body, and a rainwater inlet 14 communicating with the inner cavity of the pool body is opened on the cover plate. The partition wall is arranged in the pool body, and divides the pool body into a rainwater pool 8 and a sewage pool 3. The water in the rainwater pool 8 can be directly discharged into the river, and the water in the sewage pool 3 is transported to the sewage treatment plant. The flow distribution tank 13 is rotatio...

Abstract

The invention provides a municipal rainwater and sewage diversion device and method. The municipal rainwater and sewage diversion device comprises a pool body, a cover plate, a partition wall and a diversion groove with an opening, wherein the cover plate is arranged at the top end of the pool body, and a rainwater inlet is formed in the cover plate; the partition wall is arranged in the pool body and divides the pool body into a rainwater pool and a sewage pool; the diversion groove is rotationally connected with the inner wall of the pool body through a rotating shaft and is positioned between the top end of the partition wall and the rainwater inlet; the opening of the diversion groove is opposite to the rainwater inlet, and a water outlet hole is formed in the side wall, located on one side of the sewage pool, of the diversion groove; the water outlet amount of the water outlet hole is smaller than the water inlet amount of the rainwater inlet in the case of heavy rain and larger than or equal to the water inlet amount of the rainwater inlet in the case of light rain. According to the municipal rainwater and sewage diversion device and method, sewage and rainwater diversion is carried out when rainfall is different, the situation that rainwater and sewage mixed water with substandard water quality is discharged into a river channel to cause pollution is avoided, and meanwhile the situation that the rainwater and sewage mixed water with the substandard water quality is conveyed to a sewage treatment plant to waste resources of the sewage treatment plant is avoided.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to a municipal rain and sewage diversion device and method. Background technique [0002] At present, the old urban areas in domestic cities still have a lot of rainwater and sewage combined drainage systems, and a lot of sewage is directly discharged into rivers with rainwater. The problem of black and odorous urban water bodies is becoming more and more serious, seriously polluting the environment. Some of them have set up rainwater and sewage interception devices at the river entrances, and use rainwater and sewage to be intercepted and sent to the sewage treatment plant at the same time. However, this increases the treatment capacity of the sewage treatment plant and seriously wastes the resources of the sewage treatment plant. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a municipal rainwat...
