Biological filter deodorization project
Biological filter deodorization project, air volume: 20000m ³/ h. Biological reaction system: After being collected by covering the sewage tank, the exhaust gas enters the pre-treatment section of the biofilter through a pipeline. The acidic gas (such as H2S) in the exhaust gas is neutralized and washed using alkaline solution. The exhaust gas that has been chemically washed by alkaline solution passes through the biofilter external treatment section of the biofilter and passes through the filter bed composed of filter materials from the bottom of the filter bed. The foul odor gas is transferred from the gas phase to the water microbial mixed phase, It is decomposed by microbial metabolism fixed on the filter material.
Exhaust gas emission system: composed of explosion-proof fans, high-altitude emission chimneys, and towers, with exhaust gas treatment outlet indicators lower than the designed emission standards. It has been in operation since April 2021.
