Two-stage stratified post air-induced ring energy type deodorization system and deodorization process

Abstract

The invention provides a two-stage stratified post air-induced ring energy type deodorization system and deodorization process. The system comprises a pretreatment section and a biological section; the pretreatment section successively comprises a first circulating mixed liquor upper-layer releasing unit, a first upper-layer packing area, a first circulating mixed liquor lower-layer releasing unit, a first lower-layer packing area and a first built-in storage unit from the top down; the biological section successively comprises a second circulating mixed liquor upper-layer releasing unit, a second upper-layer packing area, a second circulating mixed liquor lower-layer releasing unit, a second lower-layer packing area and a second built-in storage unit from the top down. By adopting the two-stage stratified post air-induced ring energy type deodorization system and deodorization process disclosed by the invention, high-efficient removal of odors can be realized, and flexible schedulingof process operation is further realized, the management and maintenance are simple and convenient, the investment and energy consumption are relatively reduced, the treatment effect is reliable and stable, and the suitability, economy and sustainability are fully exerted.

Description

technical field [0001] The invention relates to the field of odor treatment, in particular to a deodorization system and a deodorization process of a two-stage layered rear-mounted air-introduction ring energy type. Background technique [0002] With the acceleration of urban development and industrialization, the application area of ​​sewage treatment facilities has become more and more extensive, and the accompanying odorous gas pollution has become a hot environmental issue that people focus on. A large amount of foul-smelling gases such as hydrogen sulfide, ammonia or other sulfur-containing gases will cause varying degrees of poisoning to human breathing, digestion, cardiovascular, endocrine and nervous systems, and even easily cause human beings to suffer from miscellaneous diseases. For countries like my country, where sewage treatment is still facing a severe situation, it is necessary to strictly control the emission of odorous gases that are incidentally produced. ...

AI Technical Summary

Problems solved by technology

[0003] The traditional deodorization technology has low purification efficiency, high energy consumption and treatment costs, and is easy to cause secondary pollution. It is restricted by weather and other conditions, which limits its scope of application.
