After organic waste gas treatment,the emission concentration of an electronic enterprise in Changzhou city does not meet the standard.After investigating the types and concentrations of pollutants in waste gas,the original secondary activated carbon adsorption device is upgraded to a"dry filtration+zeolite wheel+catalytic combustion"device.After the process transformation,the non methane total hydrocarbon emission concentration is less than 20 mg/m3,the removal rate is not less than 92%,and the waste gas emissions meet the Comprehensive Emission Standards for Air Pollutants(DB 32/4041-2021).The annual operating costs of facilities have been significantly reduced,resulting in significant economic benefits.
