Abstract

The invention relates to a sewage treatment system. The sewage treatment system comprises a preprocessing system, a biochemical treatment system, a mud-water separating system and a deep treatment system, wherein the preprocessing system comprises an oil removal grit chamber, a homogenizing regulating tank and a coagulative precipitation tank; the biochemical treatment comprises a multi-stage anoxic / aerobic biochemical tank and an anoxic / aerobic (A / O) tank; the mud-water separating system comprises a horizontal precipitation tank and a radial-flow precipitation tank; the deep treatment system comprises a coagulation air floatation tank and an activated carbon adsorption tank. The sewage treatment system disclosed by the invention aims at solving a problem of serious sewage pollution and water source waste in leather preparation industry.

Description

technical field [0001] The invention relates to a sewage treatment system. Background technique [0002] The leather preparation industry is an industry that produces a large amount of sewage. The tannery sewage is not only a large amount, but also a kind of complex and high-concentration organic wastewater. In recent years, due to the gradual improvement of people's living standards, the country's policies and regulations on environmental protection Gradually improving, people's awareness of environmental protection is constantly increasing, and they all realize that pollution control is very important. Although many companies have invested in pollution control facilities by themselves, the results are not satisfactory, and they still cannot meet the national wastewater discharge standards. The serious waste of resources cannot be improved. Contents of the invention [0003] The invention provides a sewage treatment system to solve the serious problems of sewage ...
