Odor treatment system and odor treatment technology for improving discharging standards of brewery wastewater

Abstract

The invention discloses an odor treatment system and an odor treatment technology for improving discharging standards of brewery wastewater. The system is the odor treatment system for improving the discharging standards of the brewery wastewater. The system subsequently comprises an odor collecting device, an alkali spraying tower, a biofilter, a dehydrator, a plasma reactor, a catalytic activated carbon deodorization device and a gas exhausting device which are communicated by pipelines; sodium hydroxide absorption liquid is sprayed in the alkali spraying tower; microorganisms for absorbing odor are arranged in the biofilter; high-energy electrons for degrading odor molecules are generated in the plasma reactor. The technology comprises the steps of spraying the sodium hydroxide absorption liquid to the odor in the alkali spraying tower (2) and the like. The odor treatment system and the odor treatment technology disclosed by the invention have the advantages of optimal technology, clear and concise route, stable treatment effects, simple operation, convenience in operation management and the like.

Description

technical field [0001] The invention relates to the technical field of environmental pollution control, in particular to a system and process for improving the odor of beer wastewater. Background technique [0002] Odor is one of the important public hazards that pollute the environment and endanger human health. [0003] The malodorous substances produced by the treatment of beer wastewater mainly come from the sulfur- and nitrogen-containing substances (such as hydrogen sulfide, ammonia) produced by the decomposition of organic matter by microorganisms, and low-molecular-weight fatty acids, amines, mercaptans, sulfides, indole and other organic substances . Main odor substances: ammonia and hydrogen sulfide, methyl mercaptan, methylamine, etc., in which the concentration of H2S is 0.75-1.50mg / m3, the concentration of NH3 is 0.50-2.83mg / m3, and the concentration of odor (odor value) is about 8000 . [0004] These substances are more harmful to human health, as detailed b...

AI Technical Summary

Problems solved by technology

The formulation of odor pollutant discharge standards (odor concentration) is based on human smell standards, and considers the possibility of economic investment and technical feasibility, but is affected by living habits, cultural education, living standards, economic development, urban planning layout, etc. Due to the influence of factors, in some cities where the planning and layout are limited due to the shortage of land resources, the brewery is built near the residential area. Although the odor of the brewery meets the standard, the odor of the residential area is obvious, and the environmental protection department receives more and more complaints about odor pollutants. , the contradiction between factories and groups has become increasingly prominent
