Multi-layer structure pressure type water purification treatment equipment with drainage cap in the filter area

Abstract

A multi-layer structure pressure type water purification treatment device with a drainage cap in the filter area, which includes a shell (1), and the shell (1) is provided with at least two mutually independent settling areas (2) and A filter area (12), the filter area (12) is located in the lower part of the shell (1), the upper part of the sedimentation area (2) is provided with a clean water collection area (6), the clean water collection area ( 6) After being collected by the clean water collection pipe (7), it is collected in the upper part of the filter area (12), and one end of the water outlet pipe (8) is connected with the filter water area (13) at the lower part of the filter area (12), and the water outlet pipe (8) ) is connected to the subsequent water equipment, and a backwash water pipe (16) is installed in the filtered water area (13), which is characterized in that a perforated plate (17) is installed on the lower part of the filtered water area (12) ), a perforated plate (17) and a drain cap (14) are installed on each hole. The invention has the advantages of simple structure, high treatment efficiency, low outlet water turbidity, convenient manufacture, low investment and high cost performance.

Description

technical field [0001] The present invention relates to a kind of sewage treatment equipment, especially a kind of oily sewage treatment equipment. Specifically, it integrates reaction, sedimentation, filtration and mud discharge, and has the advantages of saving chemical input, saving electric power resources, saving investment, reducing The filter area of ​​the turbidity of the effluent is equipped with a multi-layer structure pressure water purification treatment equipment with a drainage cap. Background technique [0002] At present, the sewage discharged from steel rolling and steelmaking workshops of iron and steel metallurgical enterprises contains a large amount of oil, scale, sediment, suspended solids, etc. These impurities need to be precipitated and filtered by adding chemicals. At present, there are only two independent equipments on the market, the chemical degreaser and the inclined plate precipitator, which use chemical reaction and physical precipitation for...
