Abstract

The invention relates to a foul gas collecting and treating system for chemical industry sewage, belongs to the technical field of sewage and waste gas treatment. The system comprises a foul gas collecting device, an acid washing tower, an alkaline washing tower, a demister, a UV photolysis reactor, an activated carbon adsorption device, an induced draft fan, a chimney and a plant gel treatment device. The foul gas collecting and treating system has the advantages of high safety, low cost and stable and up-to-standard emission of waste gas, enhances the flowability of gas in a closed space through reasonable gas flow organization, and is safe, stable and reliable in the operation process.

Description

technical field [0001] The invention belongs to the technical field of sewage and waste gas treatment, and in particular relates to a system for collecting and treating malodorous gas from chemical sewage. Background technique [0002] At present, the industrial production of polyoxymethylene generally includes production units such as formaldehyde, paraformaldehyde, dioxane, and polyoxymethylene, and the industrial production of adipic acid generally includes production units such as nitric acid, cyclohexanol, cyclohexanone, and adipic acid. The mixed sewage of POM and adipic acid contains various pollutants and toxic substances such as formaldehyde, methanol, benzene, formaldehyde polymer, cyclohexanol, cyclohexanone, and nitrate. The mixed sewage is alkaline, the appearance is light yellow and turbid, and it has an unpleasant smell. The water quality and quantity vary greatly with time. Generally, the COD of comprehensive wastewater is 1500-2000mg / L, BOD is 800-1000mg / L,...
