If the industrial waste gas is directly discharged into nature without treatment, it will seriously affect the air quality, affect the health of surrounding residents and the ecological system, and even cause damage to the surrounding ecological system and affect the survival and reproduction of animals and plants. Therefore, the industrial waste gas needs to be purified. The existing waste gas treatment mostly adopts UV photolysis equipment, which uses high-energy UV ultraviolet light beams to irradiate malodorous gas, changes the molecular chain structure of malodorous gas such as ammonia, trimethylamine and hydrogen sulfide, and makes the molecular chain of organic or inorganic high-molecular malodorous compounds degrade into low-molecular compounds such as CO2 and H2O under the irradiation of high-energy ultraviolet light beams. The current UV photolysis equipment has the problems of insufficient treatment capacity for high-concentration organic waste gas, rich ozone in the discharged gas, poor waste gas treatment effect, increased waste gas treatment cost and slowed waste gas treatment efficiency.
