Abstract

The invention relates to a continuous and rapid emergency treatment method of methyl mercaptan odor by employing chemical absorption and utilizing an oxidation method. The method comprises the following steps: absorbing methyl mercaptan odor under the normal temperature and normal pressure reaction conditions by utilizing alkali liquor with the pH of not less than 11, and oxidizing and removing the methyl mercaptan odor by utilizing peroxymonosulfate. The method has the advantages that the alkali liquor absorption and oxidation removal advantages are combined, and the methyl mercaptan odor which is difficult to dissolve and treat is treated in the odor; the methyl mercaptan can be fully oxidized and is difficult to transfer; the peroxymonosulfate and the methyl mercaptan reaction is fast and is instantaneously carried out, secondary pollution is avoided, and the method is suitable for performing rapid emergency removal on the methyl mercaptan odor in the accident under alkaline conditions; continuous air suction can be kept in the reaction system, and the gas is continuously recycled; the reaction conditions are mild under normal temperature and normal pressure; and the method is easy to operate and good in treatment effect.

Description

technical field

[0001] The invention belongs to the technical field of malodorous gas treatment, and in particular relates to an emergency and rapid treatment method for removing the odor of methyl mercaptan, in particular to a method for removing the odor of methyl mercaptan by chemical absorption and oxidation. Background technique

[0002] Wastewater treatment plants, public facilities, petrochemical plants, paper mills and other factories and livestock and poultry farms will produce a large amount of malodorous gas, which has a great impact on the surrounding environment. With the development of society, people pay more and more attention to malodorous gas. . The composition of malodorous gas is relatively complex, consisting of sulfides, nitrogen compounds and some volatile organic compounds. Methyl mercaptan gas is one of the main odorous gases, which mainly comes from kraft pulp, oil refining, gas, pharmaceuticals, pesticides, synthetic Resin, synthetic fiber, rubber...
