Waterpower auto-control separate system pipe network catch pit

Abstract

The invention discloses a waterpower auto-control separate system pipe network catch pit. The waterpower auto-control separate system pipe network catch basin comprises a pit body, wherein a rainwater inlet pipe is arranged on the left end of the pit body, and a drain pipe communicated with natural water body is arranged on the right end of the pit body; an early stage rain intercepting pipe, a slag stop float bowl and a multi-level adjustable overflow plate are sequentially arranged on the side wall of the pit body from left to right; the early stage rain intercepting pipe is arranged at the bottom of the side wall of the pit body, and a float bowl intercepting check valve is arranged on the early stage rain intercepting pipe; the slag stop float bowl and the multi-level adjustable overflow plate are arranged on a runner of the pit body. According to the waterpower auto-control separate system pipe network catch pit, the float bowl intercepting check valve is arranged at the orifice of the early stage rain intercepting pipe, the intercepting for early stage rainwater is realized, the rainwater backflow of the early stage rainwater in the rainwater pipeline is also prevented, the float bowl intercepting check valve is simple in structure and convenient to operate; the slag stop float bowl avoids the blocking phenomenon; the height of the multi-level adjustable overflow plate can be adjusted in large range, and the adjustment of the drainage water level is realized; the effective separation of early rainwater is realized, and the early stage rainwater is intercepted and stored in a rainwater storage pond to the greatest extent, and is then delivered to a sewage treatment plant.

Description

technical field [0001] The invention relates to drainage system equipment, in particular to a hydraulic self-controlled diversion 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 se...

Problems solved by technology

At present, the interception pipe network system is usually used to intercept the initial 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 solids and solid particles in the water, Directly discharged into natural water bodies, but the current initial rain interception facilities have the following disadvantages: 1) The structure of the interception equipment is complex and the operation is difficult; 2) The filter equipment is easy to block during the pretreatment of the later rainwater before discharge; 3) The drainage water level Fixed and not adjustable
