Abstract

This invention relates to green technique, which is a catalyzer oxidation to biology reaction container waste gas process device composed of biology reaction container, catalyzer oxidation device and drying device. The container is filled with stuff and has one air-in mouth down the sidewall with a hole pipe and one water-out on the other sidewall down. Its topside wall has spray liquid-in mouth and hole pipe and there is set with air-out pipe, wherein the air-out pipe is connected with the dryer and the dryer is connected with the catalyzer oxidation device. The catalyzer oxidation device is located with oxidation catalyzer with air-out mouth in the down part.

Description

technical field [0001] The invention relates to the field of environmental protection technology, and belongs to equipment for treating waste gas by using a bioreactor, in particular to catalytic oxidation-bioreactor waste gas treatment equipment. Background technique [0002] A large amount of polluting gases are produced in most industrial and agricultural production processes and transportation power systems. Pollutants in exhaust gas include volatile organic pollutants and malodorous substances. These pollutants are released into the air. On the one hand, they cause odor, damage the human body, destroy crops, form smog, and cause local pollution; The greenhouse effect brings regional effects. With the improvement of people's living standards, the public has increasingly strong requirements for environmental quality. Some developed countries have formulated relevant environmental protection laws to strictly control the discharge of these pollutants, requiring enterpris...
