Biochemical reaction sewage treatment system

Abstract

This invention relates to a biochemical event sewage treatment technique, which includes processing equipment and technology. This equipment is made up of anaerobic tank, adjusting tank, biochemistry mixing reaction tank, contact aerator, cleaning and depositing tank, micro-organism bearer, and aerating apparatus. Tanks connects with next processing tank by 90deg.C bending tube that intercepts big solid particles, oil and fat, and suspended matter. Level difference between first tank and last tank is 10-20cm. Tank bottom and edge have aerating apparatus. Utilize superiority micro-organism bacterium to carry out biochemical event processing, anaerobic and aerobic fore treatment, water quality and quantity adjusting tank processing, micro-organism biochemical event processing, aerating to increase oxygen, precipitating, and purification treatment. Transform into carbon dioxide and water, if reaches standard, volley. This invention utilizes ground equipment. It does not change previous ground state; Utilize superiority micro-organism bacterium to process domestic sewage. Effect is good. Cost is low. Drop strain only once. Equipment is simple. It has no noise. Mud is cleansed many years once. It is easy to operate.

Description

technical field [0001] The invention relates to a treatment technology for treating domestic sewage and kitchen waste water by adopting a biochemical method and using microbial strains. Background technique [0002] At present, environmental protection has received more and more attention from all walks of life, and people's awareness of environmental protection has become stronger and stronger. Although many large-scale sewage treatment facilities are constantly being built, only part of the sewage is treated, and there are many scattered and small sewage generation sites, including small restaurants, hotels and farmhouses, as well as some enterprises and institutions. Since the water treatment network has not yet covered all drainage systems, these sewage generating sites have become a blind spot for environmental protection, and the generated sewage is directly discharged into the water body, polluting our tense and limited water resources.

AI Technical Summary

Problems solved by technology

The traditional domestic sewage treatment methods mainly include activated mud method, contact oxidation method, etc. The disadvantages of these treatment processes are 1), poor impact resistance to sewage, and difficult to meet water quality standards; 2), long start-up time; 3), Large area, many equipment and electrical appliances, high failure rate, high operating noise, 4) large project investment and high operating costs

As long as there is oil pollution, domestic sewage treatment is more complicated
