Embodiment 1

[0038] The embodiment of the present invention proposes a multi-stage serial bio-integrated deodorization method and device, using biological pre-washing, primary biological treatment and secondary biological treatment multi-stage serial process to process malodorous gas, and different processing units have different processing principles , where the first-level biological treatment unit and the second-level biological treatment unit are different in the way of air intake, filling materials and inoculation growth of microorganisms. The collected malodorous gas first enters the biological pre-washing unit, and the malodorous gas is mixed with the atomized biological pre-washing bacteria solution, and the liquid after absorbing and degrading the malodorous gas falls into the bottom pool. The pool is connected to an external water tank, and the biological pre-washing solution is recycled. The microorganisms in the biological pre-washing solution degrade and absorb some odorous pol...

Abstract

The invention provides a multi-stage tandem type bio-integrated deodorization method and device. The device comprises a biological pre-washing unit, a primary biological treatment unit, and a secondary biological treatment unit which are connected in series; the biological pre-washing unit receives a malodorous gas; the malodorous gas is mixed with atomized biological pre-washing bacterial liquid;liquid absorbing and decomposing the malodorous gas falls into a bottom pool; the first biological treatment unit is filled with polyhedral hollow ball fillers; the secondary biological treatment unit is filled with secondary foamed polyurethane particle sponge fillers; the malodorous gas is respectively absorbed, adsorbed and degraded by microorganisms attached to the fillers when passing through the fillers in the primary biological treatment unit and the secondary biological treatment unit. The multi-stage tandem type bio-integrated deodorization method and device provided by the inventionrealize up-to-standard treatment of the malodorous gas while operating at low energy consumption and low cost so as to reduce pollution of the malodorous gas on atmosphere.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a multi-stage serial bio-integrated deodorization method and device. Background technique [0002] The existing malodorous gas treatment methods mainly include adsorption method, absorption method, combustion method, photo-oxygen catalysis, low-temperature plasma, etc., and various treatment methods have different advantages and disadvantages and application ranges. Among them, the treatment method of absorption method is too simple, and cannot effectively remove odor pollutants when dealing with high-concentration odor gases. The adsorption method is suitable for treating low-concentration malodorous gases, and the adsorption device needs to replace the adsorption packing regularly. The low-temperature plasma method has high energy consumption and has certain safety risks. Combustion treatment of exhaust gas consumes fuel and produces secondary pollution, incre...
