Problems solved by technology

[0003] The existing malodorous gas treatment technology mainly adopts single adsorption method, absorption method, combustion method, photo-oxygen catalysis, low-temperature plasma and other technologies. Although the equipment technology is mature, the treatment method is too single and cannot be effective for complex malodorous gases. achieve compliance

Abstract

The invention provides an integrated treatment method and apparatus of odor and peculiar-smell gas. The integrated treatment apparatus comprises a suspended biological absorption area, a biological filtering adsorption area and a composite active carbon adsorption area; the suspended biological absorption area receives odor and peculiar-smell gas, the odor and peculiar-smell gas enters an aerationmain pipe and an aeration branch pipe to be uniformly aerated, ammonia pollutants and sulfides in the odor and peculiar-smell gas are degraded by a mixed solution of ammonia oxidizing bacteria and nitrous acid oxidizing bacteria microorganisms; the odor and peculiar-smell gas is suspended and absorbed by virtue of a strengthened washing pump; in the biological filtering adsorption area, the substances such as hydrogen sulfide in the odor and peculiar-smell gas are degraded by virtue of heterotrophic bacteria and fungi inoculated on composite biological filler; and the composite active carbonadsorption area comprises a granular active carbon adsorption area and a honeycomb active carbon adsorption area. By adopting the integrated treatment apparatus, the odor gas is continuously treated in multiple levels in a single device to reduce the loss of air pressure and the energy consumption of the device, so that the floor occupation area of the device is saved, and the operation and maintenance expense can be reduced.

Description

technical field [0001] The invention relates to the technical field of malodorous gas treatment, in particular to an integrated treatment device for malodorous gas. Background technique [0002] With the acceleration of China's urbanization process and the continuous improvement of people's living standards, people consume a large amount of resources and produce a large amount of domestic waste and sewage. In the process of domestic waste and sewage treatment, a large amount of hydrogen sulfide and ammonia will be produced. , methyl mercaptan, ethane mercaptan, methyl amine and volatile organic compounds and other foul-smelling gases, these gases will not only corrode the daily production equipment, pollute the air environment, but also bring harm to the health of workers and nearby residents harm. [0003] The existing malodorous gas treatment technology mainly adopts single adsorption method, absorption method, combustion method, photo-oxygen catalysis, low-temperature pl...
