Comprehensive environmentally-friendly multifunctional sewage treatment system

Abstract

The invention discloses a comprehensive environmentally-friendly multifunctional sewage treatment system. A water volume and water quality adjusting pool D can conduct primary filtering conveniently on sludge and large impurity particles, is good in filtering treatment effect, and can conduct circulating filtering treatment on sewage. A hydrolytic acidification reacting pool E can improve the mixed contact effect of microorganisms and wastewater, and the reaction effect can be stabilized; sludge discharging and feeding can be conducted conveniently; wastewater can be input quantitatively. A waste gas treatment device B can clear off hydrogen sulfide, carbon monoxide and methane without manual feeding. A / O biochemistry pool G is arranged, so that the area occupied by a device is reduced, and the sludge is convenient to recycle and utilize. An aerating device C can realize single driving and multiple purposes, reduce energy losses, and conduct sufficient aeration on sewage. A chlorine dioxide generator A can liquefy, conveniently store and transport chlorine dioxide, operation and control are convenient, and manufacturing costs are low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a comprehensive environment-friendly multifunctional sewage treatment system. Background technique [0002] With the vigorous development of industry, the construction of various chemical plants, the discharge of a large amount of waste water, and the environmental protection problems are becoming more and more serious. In order to further solve the waste water problem, water resources are recycled. [0003] The hydrolytic acidification reaction tank can improve the biodegradability of wastewater, and is favored by various chemical plants. The hydrolysis and acidification reaction is divided into two parts, namely the hydrolysis stage and the acidification stage. In the hydrolysis stage, the macromolecules or cyclic organic substances in the wastewater are broken or ring-opened under the action of extracellular enzymes and converted into small molecules that can penetra...

AI Technical Summary

Problems solved by technology

The existing MBR membrane bioreactor membrane module has a large filtration load per unit time, which causes the problem of short service life of the membrane module, and the sludge is directly filtered through the membrane, and a large amount of sludge is attached to the membrane module. On the one hand, It is not easy to clean, on the other hand, it is more difficult to recycle the sludge, and there are aspects to be improved

The manufacturing cost of the existing aeration device is high, and multiple drives are required for the operation of the driving equipment. At the same time, it is impossible to fully aerate the bottom of the sewage, and the aeration efficiency is low.

The existing chlorine dioxide generator produces chlorine dioxide gas, which needs to be compressed and stored, so it is not convenient for storage and transportation. At the same time, the equipment is cumbersome and inconvenient to operate, and the manufacturing cost is high

Existing waste gas treatment devices can only treat one of these toxic gases, and cannot effectively clean up the poisonous gas, and require continuous manual feeding to clean the gas, which wastes labor costs
