Industrial production sewage treatment system

Abstract

The invention discloses an industrial production sewage treatment system. The industrial production sewage treatment system comprises a shell, wherein a water inlet and a water outlet are formed in the two sides of the shell; sewage enters the shell from the water inlet, sequentially flows through a baffling adjustment zone, a multilayer filter system, a facultative anaerobic settling zone, a buffer zone, an aerobic zone, a settling zone, a purifying zone and an outlet water tank, and finally flows out from the water outlet; the facultative anaerobic settling zone is filled with a facultative anaerobic settling zone filler; the aerobic zone is filled with an aerobic zone filler, and a micropower aeration system is arranged at the bottom of the aerobic zone; the multilayer filter system sequentially comprises a solid particle filter layer, an organic filter layer and a pebble layer from top to bottom. The industrial production sewage treatment system effectively achieves integrated treatment to industrial production sewage, can reduce toxic, harmful and coagulated substances in the industrial production sewage to the greatest extent, improves the treatment and purification efficiency of the industrial production sewage so as to enable the industrial production sewage to reach a national emission standard, reduces the economic investment cost, and meets requirements in actual use.

Description

technical field [0001] The invention relates to an industrial production sewage treatment system, which belongs to the technical field of industrial sewage treatment. Background technique [0002] With the significant improvement of people's living standards, the requirements for sewage treatment have also increased. After 1990, my country's sewage treatment has developed rapidly, and the growth rate of sewage treatment volume is 2.3 times that of the world. With continuous improvement, China's sewage treatment industry has grown rapidly, and the efficiency of township sewage treatment has also continued to improve. [0003] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is...

AI Technical Summary

Problems solved by technology

At present, the treatment and purification process of industrial production sewage in the existing technology is relatively simple. Due to the large pollution system of industrial production sewage, the existing technical treatment cannot meet the requirements of technical and discharge indicators.
