Water inlet pump chamber and method

Abstract

The invention relates to the technical field of water inlet pump chambers of sewage pretreatment systems, in particular to a construction method of a water inlet pump chamber, which are characterized in that a main body of the water inlet pump chamber is an underground structure with a cylinder type cavity structure. The cylinder type structure is composed of a cylinder wall and a cylinder bottom, the surface side of the cylinder wall is encircled by twenty-seven underground continuous walls, five layers of inner linings are arranged on the inner side of the cylinder wall and the wall faces of the underground continuous walls in the vertical direction, and a ring of lock opening top beam is arranged at the top end of the cylinder wall. A plurality of water inlet pipelines are arranged on the right side of a fourth layer of the cylinder type cavity structure, the cavity structure in a cylinder is divided into a water inlet well area, a pump chamber area and a water outlet well area from front to rear, and a pump chamber separation wall is arranged between two adjacent areas. By means of the water inlet pump chamber and the method, the water inlet pump chamber is added in sewage treatment so as to serve as an auxiliary power to avoid backflow in the sewage treatment. The design of the four pump chambers and eight outlets can enable flow rate of sewage before flowing into follow-up steps to reach sufficient accordance.

Description

[technical field] [0001] The patent of the present invention relates to the technical field of water inlet pump room of sewage pretreatment system, specifically a water inlet pump room and its method. [Background technique] [0002] With the development of society and the take-off of industrial undertakings, a lot of sewage will be produced in the city. The sewage in the city will be sent to the sewage treatment plant through the sewage pipeline for treatment and discharged to the river and sea after reaching the standard. The general sewage treatment process is as follows: [0003] The sewage flows through the sewage pipeline into the coarse and fine grid wells for pretreatment and sedimentation, and then flows into the fine grid aeration grit chamber for aeration, and then goes through the A / A / O biological reaction tank for biochemical treatment and ultraviolet disinfection The steps are arranged in Jianghai. [0004] However, when the sewage after the pretreatment of the...

Problems solved by technology

[0004] However, when the sewage after the pretreatment of the coarse and fine grid wells is discharged into the fine grid aeration grit chamber, the action of the sludge and other solids in the coarse and fine grids makes the flow rate of the sewage uneven, and sometimes even produces Backflow affects the effect of pretreatment, and the uneven flow rate of the fluid makes the force on the equipment uneven, which is likely to cause damage to the equipment
