Electric combined system pipe network intercepting well

Abstract

The invention discloses an electric combined system pipe network intercepting well. The electric combined system pipe network intercepting well comprises a well body. A rain and sewage combined water inlet pipe is arranged at the left end of the well body, a water outlet pipe communicated with natural water is arranged at the right end of the well body, an initial rain overflow weir, a residue stop floating bowl and a multistage adjustable overflow plate are sequentially arranged on a flow channel of the well body from left to right, a sewage intercepting pipe is arranged at the bottom of the side wall, between the rain and sewage combined water inlet pipe and the initial rain overflow weir, of the well body, an initial rain intercepting pipe is arranged at the bottom of the side wall, between the initial rain overflow weir and the multistage adjustable overflow plate, of the well body, and the sewage intercepting pipe and the initial rain intercepting pipe are respectively provided with an electric intercepting check valve. A sewage intercepting pipe orifice and an initial rain intercepting pipe orifice are respectively provided with one electric intercepting check valve, sewage and initial rainwater can be accurately intercepted by accurately controlling the opening of the electric intercepting check valves, and meanwhile sewage and rainwater in an initial rainwater pipeline are prevented from backflow. The residue stop floating bowl is used for stopping residues, the blockage phenomenon is avoided, and the drainage water level can be adjusted through the multistage adjustable overflow plate.

Description

technical field [0001] The invention relates to a drainage pipe network system, in particular to an electric combined pipe network interception well. Background technique [0002] The rain at the initial stage of rainfall is referred to as primary rain. In the early stage of rainfall, the rainwater dissolves a large amount of acid gas in the air, automobile exhaust, factory exhaust gas and other polluting gases. etc., causing the initial rain to contain a large amount of pollutants such as organic matter, pathogens, heavy metals, grease, and suspended solids. Therefore, the pollution degree of the initial rain is relatively high, usually exceeding that of ordinary urban sewage. If the early rainwater is directly discharged into natural The water body will cause very serious pollution to the water body, so the first rain needs to be treated. At present, the interception pipe network system is usually used to intercept the first rainwater to the sewage pipe and send it to the...

Problems solved by technology

At present, the interception pipe network system is usually used to intercept the first rainwater to the sewage pipe and send it to the sewage treatment plant for purification treatment. However, the pollution degree of the rainwater in the later period of the rainfall is relatively light. After pretreatment to intercept the suspended matter and solid particle impurities in the water, Directly discharged into natural water bodies, but the current initial rain interception facilities have the following disadvantages: 1) It is difficult to accurately control the initial rain interception flow; 2) The filter equipment is easy to block during the pretreatment of the later rainwater before discharge; 3) The drainage water level is fixed Not adjustable
