How to remove and purify the odor of waste gas from the workshop of sewage plant

Odor sources in the sewage treatment system are mainly distributed in sewage collection, pretreatment, primary treatment, filter backwash liquid and sludge treatment supernatant. Mixing in aeration tank and biological anaerobic tank will produce some odor. In addition, in the sludge treatment system, odor will also be generated during sludge concentration, sludge dehydration after anaerobic digestion, sludge stacking and transportation. Due to the compression and shearing of unstable sludge, protein-like biopolymers will be produced, which will produce a lot of odor after decomposition. For the odor removal of sewage treatment plants, sewage odor removal, sewage odor removal and sewage odor removal, it is necessary to choose exhaust gas purification technology with excellent quality and technology to achieve satisfactory results.

The original substance of malodorous gas is organic matter, which is harmful to human health. Therefore, the treatment and purification of odor and waste gas in sewage station is imperative.

GL waste gas treatment measures

The research and treatment of malodorous pollution in developed countries started earlier, especially sewage treatment plants, which have rich experience, among which the United States, Germany and Japan have made remarkable achievements. At present, the methods of odor treatment in China can be roughly summarized into four kinds from the principle of removal: physical method, chemical method, biological method and ion method.

Physical method and chemical method use a lot of equipment, the process is complex, the regeneration and post-treatment process after secondary pollution is complex, the energy consumption is high, and the operation and maintenance costs are high.

The photocatalytic oxidation method adopted by Hebei Guanglu Environmental Protection Co., Ltd. has also won the national patent, and has been successfully applied to the purification of organic waste gas, odor, dust and smoke pollution in various spraying workshops, printing workshops, electronic workshops, plastics, chemicals, enameled wires, pharmaceuticals, laboratories, sewage treatment plants and other places.
