Rainwater and sewage diversion device

Abstract

The invention discloses a rainwater and sewage diversion device. The rainwater and sewage diversion device is characterized by including a first box body, a second box body, a sewage interception basket, an uncover handle, a rainwater and sewage inlet, a hinge, a liquid level communicating vessel, a rainwater outlet, a floating ball combination and a sewage outlet; rainwater and sewage enter the first box body through the rainwater and sewage inlet, enters the bottom of the first box body through the sewage interception basket, and enters the second box body through the liquid communicating vessel. According to the rainwater and sewage diversion device, when it is not raining, the sewage in a pipeline, such as bathing water, washing machine drainage and other water bodies enter the device,floating balls of the device sink, the sewage outlet is opened, and the sewage enters a sewage treatment plant through the pipeline; at the beginning of the rainfall, the floating balls does not risecompletely, and the sewage outlet is still not closed, the initial rainwater with sludge can be collected and discharged into the sewage outlet; when the rain is heavy, the floating balls rise, a weir gate can be opened automatically, and the rainwater with low pollution concentration is discharged into a municipal rainwater pipeline, so that the natural water body cannot be affected by the pollution of the sewage or the pollution affect of the sewage on the natural water body is reduced, and the water quality of the natural water body can be improved steadily.

Description

technical field [0001] The invention relates to a diversion device, in particular to a rain and sewage diversion device. Background technique [0002] The rain and sewage diversion device is a device used to divert rainwater and sewage. Since urban sewage is collected and directly discharged into rivers will cause pollution, it needs to be collected and treated. When it rains, the rainwater does not need to be treated and will flow into the sewage treatment system. [0003] At present, the existing rain and sewage diversion device is simple in structure, mainly composed of a circular or square shaft, and an overflow baffle is set in front of the water outlet. The disadvantage is that once the city encounters a rainy season, the sewage outlet cannot automatically Closed, the rainwater will flow into the sewage pipe network through the sewage outlet while overflowing the overflow baffle, which will dilute the sewage concentration, increase the sewage treatment capacity, and g...

[0003] At present, the existing rain and sewage diversion device is simple in structure, mainly composed of a circular or square shaft, and an overflow baffle is set in front of the water outlet. The disadvantage is that once the city encounters a rainy season, the sewage outlet cannot automatically Closed, the rainwater will flow into the sewage pipe network through the sewage outlet while overflowing the overflow baffle, which will dilute the sewage concentration, increase the sewage treatment capacity, and greatly increase the operating cost of the sewage treatment plant. Drainage and sewage pressure, in order to solve this problem, various sewage discharge devices have also appeared in the drainage pipe network system, but the effect is not very obvious, and the discharge of sewage cannot be intelligently controlled
