Garbage transfer station malodorous gas treatment technique and device

Abstract

The invention relates to the technical field of waste gas purification, particularly a garbage transfer station malodorous gas treatment technique and device. The garbage transfer station malodorous gas treatment technique comprises a working mode and a disinfection mode, wherein the working mode adopts a low-temperature plasma cracking oxidation reactor and catalytic oxidation bed purification process; and the disinfection mode is implemented by the following steps: introducing air into the low-temperature plasma cracking oxidation reactor to generate ozone, hydroxy free radical and other active groups, and delivering to garbage, garbage leachate and other parts in need of disinfection treatment to perform disinfection. The garbage transfer station malodorous gas treatment device comprises a collecting system, a low-temperature plasma cracking oxidation reactor, a catalytic oxidation bed and a draught fan. The technique and device have high purification efficiency and favorable effect for malodorous peculiar smell, is slightly influenced by various environments and extrinsic conditions, and can effectively disinfect the parts in need of disinfection without influencing the biochemical properties of the garbage.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to a process for treating malodorous gas in a garbage transfer station and a device thereof. Background technique [0002] The function of the garbage transfer station is to collect the garbage from the scattered garbage collection points in the residential area, compress it, and send it to the garbage landfill. The function of the transfer station determines that the transfer station must be set in or near the residential area. Due to the rotting and smelly domestic garbage, it produces strong pungent odors such as hydrogen sulfide, mercaptans, sulfides, ammonia, and acids. The odor emitted by the transfer station has a great impact on the lives of the surrounding residents. It is one of the urban air problems that need to be solved urgently. [0003] The concentration of pollutants in the waste gas of the garbage transfer station is usually low, the concentratio...

Problems solved by technology

Although these methods have relatively high efficiency in removing odorous pollutants, the operating conditions are complex, unstable, and the cost is high, and secondary pollution may occur

[0004] In addition, when disinfecting garbage and landfill leachate, 84 disinfectant is often used at present. This method has a better disinfection effect, but at the same time it kills a large number of microorganisms, which seriously affects the biochemical properties of garbage and leachate, and affects the subsequent treatment effect.
