Technological Process of Waste Gas Treatment Equipment for Laboratory Animal Facilities

Objective The impact of technological process of waste gas treatment equipment on environment.Method The optimal plan of waste gas treatment for laboratory animal facilities has been found out by analyzing the experimental result of water spray absorption method,photooxidation,low-temperature plasma decomposition method and water spray dosing method. And the most effective deodorization method has been selected by comparing the concentration of gas such as ammonia,hydrogen sulfide,and odor in the inlet and outlet of equipment. Result The result showed that the concentration of ammonia,hydrogen sulfide and odor in the exhaust gas is better than that in the emission standard of odor pollutants( GB 14554—93) by adding sodium hypochlorite water or using photooxidation plasma to deodorize. Conclusion The application of sodium hypochlorite in spray water or the combination of photooxidation plasma deodorization and water spray deodorization can meet the need of deodorization in animal facilities,which are feasible from economic and technical perspective. Thus,these method can reduce the odor content in the outlet of equipment of laboratory animal facilities and effectively solve the problem of odor around the facility,which have the advantages of high efficiency and energy saving,and can be promoted and applied in laboratory animal facilities.
