Description

technical field

[0001] The invention relates to an aerobic internal circulation reflux immobilized microorganism fluidized bed reactor. Background technique

[0002] Due to the increasingly serious environmental pollution, the country is paying more and more attention to environmental governance. Especially with the implementation of the new socialist countryside construction in the whole country, it has become the focus of the country's "Eleventh Five-Year Plan" to strengthen the transformation of rural ecological environment and strengthen the construction of rural infrastructure, especially in the treatment of water environment, sewage treatment facilities and equipment research and development. The invention of this country is aimed at the actual problem of sewage treatment, and develops a new type of internal circulation backflow immobilized microbial fluidized bed reactor to improve the sewage treatment effect, especially the nitrogen removal efficiency.
