Hunan Tobacco Industry Co., Ltd. Changde Cigarette Factory Sewage and Waste Gas Treatment


The tobacco industry

In response to the odor pollution problem in sewage treatment plants, our company has innovatively applied an integrated technology of "covering and sealing + biological treatment". Through the dual effects of source sealing and microbial decomposition, it effectively eliminates the dispersion of odors such as hydrogen sulfide. Compared with traditional solutions, the operating cost is reduced by 35%, achieving compliance with the "Emission Standard of Odorous Pollutants" for treatment This technology has been successfully applied to more than ten provincial key projects in the tobacco industry. Meanwhile, in the phosphine treatment project in Shiban Tan, Changde, a negative pressure collection - three-stage purification system was adopted to efficiently recover and treat the exhaust gas from the reservoir area. After testing, the emission concentration was stably 30% lower than the limit value of the "Integrated Emission Standard of Air Pollutants", forming a replicable solution for the treatment of hazardous chemical gases.
