Sewage plant in the workshop odor odor to remove how to purify

The source of odor in the sewage treatment system is mainly distributed in the sewage collection, pretreatment, primary treatment and filter backwash, sludge treatment supernatant, etc., the mixing of the aeration tank and anaerobic tanks will produce part of the odor. In addition, the sludge treatment system in the sludge concentration, anaerobic digestion after sludge dewatering and sludge stacking, transportation process will also have odor, due to the unstable sludge compression, shear effect, resulting in protein biopolymers, the decomposition of which produces a lot of odor. For sewage treatment plant in addition to odor, sewage in addition to odor, sewage plant in addition to odor, sewage in addition to odor, to choose the quality and technology of exhaust gas purification technology, in order to achieve satisfactory results.

Odor gas generated by the original material for organic substances, these substances are more harmful to human health. Therefore, the treatment and purification of sewage station odor exhaust gas is imperative.

GL waste gas treatment measures

Developed countries in the odor pollution, especially on the sewage treatment plant odor pollution research and treatment started earlier, more experienced, including the United States, Germany and Japan's results **** for significant. Domestic current malodor treatment method from the principle of removal can be roughly summarized into physical, chemical, biological and ionic treatment of four types.

Physical and chemical methods used in a wide range of equipment and process complexity, secondary pollution after regeneration and post-treatment process is cumbersome, energy consumption, operation and maintenance costs are high.

Hebei Guanglu environmental protection use of photocatalytic oxidation method of organic waste gas treatment has also obtained a national patent, and successfully applied in various types of spraying workshop, printing workshop, electronic plants, plastics, chemicals, enameled wire, and pharmaceuticals, laboratories, sewage treatment plants, and other places in the purification and treatment of organic waste gas, odor, dust, smog pollution.
