NAS immobilized carrier microorganism generator and technology for treating sewage by NAS solidified carrier microbial generator

Abstract

The invention discloses an NAS immobilized carrier microorganism generator and a technology for treating sewage by using the NAS immobilized carrier microorganism generator. The NAS immobilized carrier microorganism generator comprises a barrel-shaped shell, a cover body arranged at the upper end of the shell, and a first aeration pipe which penetrates through the cover body and is fixedly connected to the inner bottom of the shell, and a through hole penetrating through the shell is arranged; a microorganism immobilized carrier is filled between the inner wall of the shell and the outer wallof the first aeration pipe, wherein the microorganism immobilized carrier is a 1-5 cm porous ceramic material prepared by mixing and firing clay and diatomaceous earth in the mass ratio of 50: 1; microorganisms extracted from nature and transfer enzymes are combined in a carrier in a dormant manner by adsorption, covalent bonding and embedding. The technology can be used for replacing a link of culturing the microorganisms by utilizing activated sludge when the sewage is treated by an activated sludge method, high-concentration microbial flora can be continuously supplied to the sewage for a long time without addition, no activated sludge is not generated in the sewage treatment process, and the effect of zero emission of the sludge is achieved; and the technology can also be applied to microorganism treatment of polluted water bodies of lakes and rivers and other polluted water bodies.

Description

technical field [0001] The invention relates to the technical field of sewage microbial treatment, in particular to a NAS solidified carrier microbial generator and the sewage treatment technology of the generator. Background technique [0002] At present, most sewage microbial treatment technologies use the method of regularly injecting microbial agents or activated sludge to cultivate microorganisms. The method of regularly injecting microbial agents has poor sustainability, unstable system, easy loss, easy to be damaged, complex operation, and high input costs. Big and other issues. The activated sludge method is an aerobic biological treatment method for sewage, which was invented and applied by Clark and Gage in Manchester in about 1913 at the Lawrence sewage test station in Manchester. Today, the activated sludge process and its derivative improvement process are the most widely used methods for treating sewage. It can use nutrients in sewage to cultivate microorgani...

AI Technical Summary

Problems solved by technology

The remaining activated sludge contains a large number of harmful substances such as germs and heavy metals, and is a high-risk waste. The sludge needs to be dehydrated and disposed of safely during treatment, which is time-consuming and laborious
