Interceptor well with non-return function

Abstract

The invention discloses an intercepting well with a check function. The intercepting well comprises a well body; a water inlet pipe is arranged on a first side wall of the well body; a water outlet pipe is arranged on a second side wall of the well body; a flow discarding port connected with a flow discarding pipe is formed in the bottom of a third side wall of the well body; a float ball intercepting apparatus is arranged at the flow discarding port; a fixed check gate is arranged in the well body and close to a pipe orifice of the water outlet pipe; and a buoyancy box type check gate is arranged at the top of the side, close to the water outlet pipe, of the fixed check gate. According to the intercepting well disclosed by the invention, the mode of combining the float ball intercepting apparatus, the fixed check gate and the buoyancy box type check gate is utilized to carry out control, so that the functions that first rain is intercepted to a sewage treatment plant, later rain does not enter the sewage treatment plant and in case of heavy rainfall, rain can be discharged at high flow are achieved, and meanwhile, the role of preventing natural water from flowing back can be played.

Description

Technical field [0001] The invention belongs to the technical field of drainage pipe networks, and specifically relates to an intercepting well with a check function. Background technique [0002] After the initial rain washed the air and the ground, it carried a lot of toxic and harmful substances. Investigations show that the initial rainwater carried more toxic and hazardous substances than domestic sewage. If the initial rainwater is directly discharged into rivers and lakes, it will seriously pollute the water environment. Therefore, the initial rainwater needs to be treated. At present, a simple interception well system is usually used to intercept the initial rain to the sewage pipeline and send it to the sewage treatment plant for purification. However, the rainwater at the later stage of the rainfall is less polluted and directly discharged into the natural water body, but the later rainwater can still enter the sewage Pipes, waste resources. Summary of the invention ...

Problems solved by technology

At present, a simple interception well system is usually used to intercept the first rainwater to the sewage pipe and send it to the sewage treatment plant for purification treatment. The pollution degree of the rainwater in the later period of the rainfall is relatively light, and it is directly discharged into the natural water body, but the later rainwater can still enter the sewage pipes, waste of resources
