A waste water advanced treatment device

Abstract

The invention discloses a waste water advanced treatment device, which can greatly improve the treatment depth of waste water. The treatment method of microorganisms is adopted, and the degradation speed of microorganisms in water can be improved by first exposing the waste water to oxygen. The microorganisms of the present invention adopt coiled bending The microbial attachment net is used to attach microorganisms, which can improve the recycling of microorganisms. During the treatment process, microorganisms will attach and multiply in large numbers, so as to realize the treatment of subsequent wastewater by microorganisms on the previous wastewater, so that uninterrupted reproduction and uninterrupted treatment , has a better treatment effect, the reaction box of the present invention is provided with a rotating microbial adsorption ball holder, which can make the microbial adsorption balls mix well with the wastewater, further realize the treatment of wastewater, and at the same time, the microorganisms on the microbial adsorption balls The reproduction speed will also be greatly increased, and the thoroughness of treatment will be enhanced. The pH adjustment of the present invention and the addition of treatment reagents according to the wastewater can be evenly mixed, which is beneficial to subsequent treatment.

Description

technical field [0001] The invention relates to a waste water advanced treatment device, belonging to the technical field of sewage treatment auxiliary equipment. Background technique [0002] China is one of the most water-polluted countries in the world, with up to 70 percent of the country's rivers, lakes and reservoirs affected. At present, for other useless water such as domestic sewage, industrial wastewater, and primary rainwater flowing into drainage pipes and canals, people used to discharge directly or after simple treatment. With the continuous emphasis on the environment in our country, the sewage The governance of the industry has also gradually increased, and this method of emission is completely unfeasible. Therefore, in recent years, people have begun to improve the technology and equipment of sewage treatment in order to improve the sewage treatment capacity as much as possible. [0003] However, the current sewage treatment generally passes the sewage thr...

AI Technical Summary

Problems solved by technology

[0003] However, the current sewage treatment generally passes the sewage through the treatment tank in turn, and then it can be discharged after rapid treatment. Although this sewage treatment method is relatively fast, the depth of sewage treatment is not good, mainly relying on chemical reactions or flocculants. After treatment, the processed product still has certain pollution

The microbial treatment method can improve the depth of sewage treatment, but the current microbial treatment method is not thorough and still has certain limitations
