Problems solved by technology

[0004] Traditional aerobic biological treatment generally includes mud methods such as traditional A/O method, SBR method, oxidation ditch method, and membrane methods such as MBR method and contact oxidation method. However, due to the high ammonia nitrogen, the nitrification reaction and denitrification process are not complete. Ammonia

Abstract

The invention discloses an aerobic treatment method applied in antibiotic wastewater treatment, and applied in a wastewater treatment A/0 biochemical system. The A/0 biochemical system comprises a pool A, a pool O, a reflowing device and a biological setting pond. A preposed efficient microorganism A/O denitrification system is established in an aerobic interior of the biochemical system; an aerobic hydrolysis pool (the pool A) and an aeration oxidization pool (the pool O) are built in a biochemical pool, and are filled with efficient microbial preparation; the optimal environment is created to continuously enlarge cultivation and domestication. The removal of ammonia nitrogen and total nitrogen is mainly implemented in a continuous flow treatment manner with the methods of strengthening the stirring of the pool A and the aeration of the pool O and controlling the reflowing of nitration liquid and the sludge return ratio, and most COD is simultaneously degraded, so that the purpose of degrading various pollutants is achieved; through the technology, the removal efficiency of various pollutants is more than 95%.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, and more specifically relates to an aerobic treatment method for antibiotic-based wastewater with high ammonia nitrogen and high organic content. Background technique [0002] Antibiotic wastewater is one of the most difficult types of industrial wastewater to treat. The wastewater has complex components, high concentration of organic matter, high concentration of soluble and colloidal solids, frequent changes in pH value, high temperature, color and odor, high content of suspended solids, easy to generate foam, contains refractory substances and has inhibitory effect Antibiotics and other toxic substances belong to the antibiotic-refractory wastewater. Considering that the biodegradability of this type of wastewater is ≧0.3, that is, the B / C ratio is high and the biodegradability is strong, the most energy-saving and effective treatment method is to use microbial treatment technol...
