Short-cut nitrification and denitrification reactor for kitchen anaerobic biogas slurry and operation method of short-cut nitrification and denitrification reactor

The invention relates to the technical field of kitchen waste treatment, in particular to a short-cut nitrification and denitrification reactor for kitchen anaerobic biogas slurry, which utilizes the waste heat of kitchen anaerobic biogas slurry inlet water due to the previous step of anaerobic fermentation process to wrap the outside of a reaction cylinder with thermal insulation cotton, so that the temperature of 30 DEG C can be maintained under the working condition without an external heat source; the invention further provides an operation method of the short-cut nitrification and denitrification reactor for the kitchen anaerobic biogas slurry, excess sludge of a traditional landfill leachate treatment system is inoculated, and the short-cut nitrification and denitrification activated sludge is enriched through two-stage sludge domestication, so that the short-cut nitrification and denitrification reactor for the kitchen anaerobic biogas slurry is obtained. And the long-term stable treatment of the kitch
