Abstract

The invention discloses an efficient biological treatment device and treatment method for waste gas. In the biological pretreatment unit, recyclable activated sludge is used for replacing water spraying and chemical agent washing to realize rapid absorption and removal of hydrogen sulfide and ammonia in the waste gas; after waste gas is pretreated by the biological pretreatment unit, the concentration of gas pollutants is reduced, then the biological treatment unit is adopted for further treatment, efficient conversion of the gas pollutants can be achieved, the phenomenon of filter material acidification is not likely to happen, and the good gas treatment effect is guaranteed.

Description

technical field [0001] The invention relates to the field of biological deodorization equipment, in particular to a waste gas high-efficiency biological treatment device and treatment method. Background technique [0002] The gas pollutants produced in the process of human production and life are easy to diffuse into the air, causing pollution to the environment, and at the same time causing harm to human health. Therefore, appropriate technical measures must be taken to deal with the waste gas before it is discharged. In recent years, my country has also stepped up the supervision of waste gas treatment and emissions. The revision of the "Odor Pollutant Emission Standard" (GB14554-93) has made more detailed and strict regulations on the areas where waste gas is generated. Therefore, exhaust gas treatment has received extensive attention in recent years. [0003] The gaseous pollutants produced by sewage treatment plants mainly include ammonia, hydrogen sulfide and volatile...
