Initial rainwater separating, collecting and processing device of rainwater and sewage confluence pipe and use method thereof

Abstract

The invention relates to an initial rainwater separating, collecting and processing device of a rainwater and sewage confluence pipe. The initial rainwater separating, collecting and processing device comprises a transfer adjustment pool and an initial rainwater tank, wherein a rainwater and sewage confluence inlet pipe, a later rainwater discharge pipe, an initial rainwater tank transfer pipe and a sewage pipe are communicated with the transfer adjustment pool, the later rainwater discharge pipe is connected with an urban rainwater pipe network, the sewage pipe is connected with a sewage pipe network, a first-stage buoy valve is arranged in the transfer adjustment pool, the first-stage buoy valve is arranged in the connecting position of the transfer adjustment pool and the sewage pipe, and the connecting position of the transfer adjustment pool and the sewage pipe can be controlled to open and close by the first-stage buoy valve along with the rising or falling of the liquid level in the transfer adjustment pool; one side of the initial rainwater tank is communicated with the transfer adjustment pool through the initial rainwater tank transfer pipe, a first-stage sewage outlet and a second-stage sewage outlet are formed in the initial rainwater tank, a second-stage buoy valve is arranged in the initial rainwater tank, the second-stage buoy valve is arranged at the second-stage sewage outlet, and the second-stage sewage outlet can be controlled to open and close by the second-stage buoy valve along with the rising or falling of the liquid level in the initial rainwater tank. The initial rainwater separating, collecting and processing device has the advantage of reasonable and simple structural design, the purpose of automatically abandoning initial rainwater can be achieved, the whole system does not need to be manually controlled, and manpower resources are saved.

Description

technical field [0001] The invention relates to a rain-sewage treatment system, in particular to an initial rainwater separation and collection treatment device for a rain-sewage confluence pipe. Background technique [0002] The initial rainwater abandonment is mainly used in the rainwater collection and utilization system. During the initial rainfall, the first 2-5mm of rainwater is generally seriously polluted and the flow rate is relatively small. In the combined rainwater and sewage pipe network, the initial rainwater needs to be discarded. The existing technology has the following problems: the grasp of the rainwater discarded flow requires manual control; the structure is complex, which is not conducive to installation and use, and it cannot be used on the existing treatment pool. Retrofitting or retrofitting requires a lot of investment; the initial rainwater abandonment is not complete or the abandonment is too much. Contents of the invention [0003] The techni...
