Waste rotary kiln degradation sewage anaerobic purification combined device

Abstract

The invention discloses a waste rotary kiln degradation sewage anaerobic purification combined device which comprises a fermentation part and a rotary kiln degradation part around the fermentation part, and a first-stage drainage channel is provided between the fermentation part and the rotary kiln degradation part. The fermentation part comprises a plurality of fermentation cylinders. The adjacent fermentation cylinders are communicated through water through holes formed in the lower middle portions of the cylinder walls, and vent holes are formed in the upper middle portions of the cylinderwalls between the adjacent fermentation cylinders. A first stage fermentation cylinder is provided with a water inlet and an exhaust port, the water inlet is connected to the first-stage drainage channel through a pipeline, and the exhaust port is connected with an air pipe joint. A sediment cleaning pipe is arranged at the top of each fermentation cylinder, and a water outlet is further providedat the top of a last-stage fermentation cylinder. The water outlet is connected to a safety air pressure storage tank through the pipeline. The rotary kiln degradation part includes a plurality of garbage degradation tanks. The bottom of each garbage degradation tank is provided with a plurality of drainage ditches and a second-stage drainage channel, each drainage ditch is communicated with the second-stage drainage channel, and the second-stage drainage channel is communicated with the first-stage drainage channel.

Description

technical field [0001] The invention relates to the fermentation and degradation treatment of domestic garbage, in particular to a combination device for degrading sewage in a garbage rotary kiln and submerging oxygen in purification. Background technique [0002] At present, in the treatment of most municipal solid waste in my country, about 10% is treated as organic fertilizer, 10% is used for combustion and power generation, and the rest is basically disposed of in landfill. [0003] Garbage organic fertilizer treatment is difficult to deal with, and the benefit is not high; to burn garbage to generate electricity, the garbage needs to be finely classified, it takes a lot of human resources, the cost of power generation is high, and the problem of waste gas treatment from garbage burning needs to be dealt with; garbage landfill, It will cause the land to become acidic and alkaline, and the garbage waste liquid will seep into the groundwater layer and pollute the water sou...
