Method and apparatus for treating solid waste

Abstract

The invention discloses a method and equipment for treating solid waste, after a receiving field receives the waste, the waste is loaded to a batching system, the batching system is transferred to an SC device in a preset amount through a conveying belt for hydrothermal treatment, and leachate generated during organic treatment of the municipal solid waste is circulated to a biological digestion device; the biological digestion device treats the leachate into biogas and digests, the biogas is input into the boiler as combustible gas, and the liquid digests in the digests are treated into purified water by the purification device and then are respectively connected into the receiving field, the accumulation tank and the exchanger; the SC device conveys the organic part of the solid waste to the solid-liquid separator after the organic part of the solid waste is treated, and the solid-liquid separator correspondingly conveys the separated liquid pasty flow and solid pasty flow to the settler and the metal separator for further treatment. The recycling efficiency of the organic part of the urban solid waste can be improved, the corresponding part is recycled, and odor emission is reduced.

Description

technical field [0001] The invention relates to the field of waste recovery and treatment, in particular to a method and equipment for treating solid waste. Background technique [0002] Disposal of the organic fraction of municipal solid waste from waste sorting is a socio-environmental concern of great concern. The organic fraction of municipal solid waste as a sustainable source of biofuel stems from the management of an increasing amount of such differentiated waste. needs. The organic fraction of MSW includes not only residues of food, grass, clippings, fruit, etc., but also includes metals, plastics, glass, inorganic inert materials, non-biodegradable materials, nut shells, crustacean shells, and mollusk shells Wait. However, the organic part of municipal solid waste generally contains substances of organic nature and has highly available carbon-carbon chemical bonds, which makes it possible for the organic part of municipal solid waste to be suitable for biological ...

Problems solved by technology

But hashed and ground organic material tends to separate from the dilution water and settle on the bottom on the one hand and float on the surface as a fibrous layer on the other, greatly slowing down the efficiency of anaerobic fermentation

[0007] Furthermore, prior art methods do not yet allow for optimized material handling and energy recovery for a circular and sustainable economy
