Tobacco flake wastewater is a type of wastewater generated during the production process of the tobacco industry, which contains high concentrations of organic matter and suspended solids. The purpose of this study was to treat tobacco flake wastewater through the combined application of Fenton technology and membrane filtration technology, and to conduct aerobic experimental studies.
Fenton technology is a commonly used advanced oxidation technology with strong oxidizing properties that can degrade organic matter. Membrane filtration technology is a method of membrane separation to separate suspended solids and dissolved organic compounds in water to achieve water purification. Combined with Fenton technology and membrane filtration technology, the organic matter in tobacco flake wastewater can be fully degraded, and suspended solids can be removed to meet the requirements of wastewater treatment.
In the experiment, we first used the Fenton technology to pre-treat the tobacco flakes wastewater. Under suitable process conditions, Fenton's reagent can efficiently oxidize and degrade organic matter in wastewater. Subsequently, the water pre-treated by Fenton is directed into a membrane filtration unit for further treatment. By using microporous membranes, suspended solids and dissolved organic compounds can be separated from the water.
The results showed that the combined application of Fenton technology and membrane filtration technology could effectively treat tobacco flake wastewater. With suitable treatment conditions, the removal rate of COD (chemical oxygen demand) of tobacco flakes wastewater can reach more than 80%, and the removal rate of suspended solids can also exceed 90%. In addition, in aerobic experimental studies, the BOD (biochemical oxygen demand) value of the treated water body was significantly reduced after a period of degradation, showing good stability and aerobic biochemical properties.
The combination technology of Fenton and membrane filtration has the advantages of simple operation, high treatment efficiency and stable effluent quality. However, the technology also faces some challenges, such as the optimization of Fenton's reagent selection and dosage, as well as the stable operation and periodic cleaning of the membrane filtration unit.
In conclusion, Fenton treatment and membrane filtration technology for tobacco flake wastewater is a promising wastewater treatment solution. This technology can efficiently remove organic matter and suspended solids in wastewater, and realize the purification and resource utilization of wastewater. Further research and promotion of this technology will provide a feasible solution for wastewater treatment in the tobacco industry and promote environmental protection and sustainable development.
