Deodorization system for landfill leachate regulating tank

Abstract

The invention discloses a deodorization system for a landfill leachate regulating tank. The system comprises a water inlet pipeline, an adjusting tank sealing device, an odor collecting device, a water-gas separator, a sucking pump, an adsorption and degradation device, a torch combustion device and an MBR biochemical device, wherein the water inlet pipeline, the regulating tank sealing device, the odor collecting device, the water-gas separator and the sucking pump are sequentially communicated; the adsorption and degradation device comprises a treatment tank and a biological filler layer; the sucking pump is communicated with the treatment tank; the biological filler layer is arranged in the treatment tank and is used for adsorbing gas pumped by the sucking pump; the MBR biochemical device comprises a biochemical pool and an activated sludge conveying pipe, the activated sludge conveying pipe is communicated with the treatment pool and used for spraying activated sludge in the biochemical pool to the biological filler layer, the treatment pool is connected with the biochemical pool through a sludge discharge pipe, and the treatment pool is connected with the torch combustion device through an exhaust pipe. The problem of odor pollution caused by the landfill leachate is effectively solved, the deodorization effect is good, the activated sludge degradation effect is high, theoperation cost is low, and the operation is simple.

Description

technical field [0001] The invention relates to a landfill leachate treatment system, in particular to a landfill leachate regulating pool deodorization system. Background technique [0002] At present, the landfill leachate produced in the domestic waste landfill process is mainly temporarily stored by building a closed large-capacity underground adjustment tank, and then centrally processed. Anaerobic fermentation provides an anaerobic environment. However, the odor control of the regulation pool has always been a difficult problem to solve. [0003] The odor in the regulating tank is mainly the metabolites produced by microbial anaerobic fermentation, which can be divided into the following types according to the chemical composition: 1) sulfur-containing compounds: such as hydrogen sulfide, sulfur dioxide, mercaptan, sulfide, etc.; 2) nitrogen-containing compounds : Such as ammonia nitrogen, amine, amide, etc.; 3) Halogen and its derivatives: such as chlorine, chlorina...
