Abstract

The invention relates to a garbage disposal system and a garbage disposal method. The system comprises a garbage crushing and extruding device, a garbage drying device, a deodorization device, a filtrate treatment device and a garbage screening device. The method comprises the following steps: S1, receiving and storing the garbage, and collecting the landfill leachate; S2, crushing and extruding the garbage at a time by utilizing the garbage crushing and extruding device, and collecting the garbage extrusion liquid; S3, performing anaerobic fermentation, nitration / denitrification and membrane treatment on the landfill leachate and the extrusion liquid; S4, biologically drying the garbage by utilizing the garbage drying device, and treating odor by utilizing the deodorization device; and S5, performing secondary crushing on the garbage, and separating out combustible components, inorganic residue soil and waste metals in the dried garbage by utilizing the garbage screening device. According to the system and the method, the landfill leachate, the garbage extrusion liquid and the odor can be effectively treated, the treated solid wastes can be sorted, the aim of recycling the resources is achieved, and the garbage treatment efficiency is obviously improved.

Description

technical field

[0001] The invention relates to a garbage treatment system and method. Background technique

[0002] The treatment and utilization of municipal waste "harmless, reduced, and resourceful" is a worldwide issue. At present, the centralized treatment methods of urban and rural municipal waste in my country mainly include landfill, composting, and incineration. The landfill method occupies a large area and has a low degree of waste reduction. It requires anti-seepage treatment, and a biogas recovery and leachate treatment plant must be built, which is likely to pollute groundwater and surrounding air. The composting method is suitable for treating waste containing a lot of perishable organic matter, and can realize the comprehensive utilization of some resources, but the quality of composting is not easy to control, and the harmful components often exceed the standard. Waste incineration power generation is developing very rapidly in my country, but the investme...
