Embodiment Construction

[0015] The process invention is composed of artificial pre-sorting, mechanical sorting, composting of organic matter, incineration of incinerable materials, brick making of building waste that can be made into bricks, utilization of heat energy and supporting auxiliary sub-processes.

[0016] The domestic waste entering the factory enters the pre-sorting field, and the recyclables are sorted out and the landfill is drained at the same time, and then enters the first screening, the underscreen enters the second screening, and the overscreen enters the aerobic waste through magnetic separation. For composting, oxygen is supplied by a high-pressure fan, and the leachate produced by aerobic composting, sorting and draining, and to-be-combusted bins enters the regulating pool. When the water in the garbage is insufficient, it is regulated by the water in the regulating pool, and the waste gas generated by aerobic composting enters the deodorizing pool for deodorization . After aero...

Abstract

The technological process of treating domestic garbage comprehensively includes artificially pre-sorting to separate recovered matter, mechanical sorting to separate organic matter for making fertilizer and percolate for fertilizer humidity regulation, producing compost with organic matter, incinerating useless matter, making brick, heat energy utilizing for producing fertilizer and brick, etc. The fume is desulfurized and dedusted before exhaust via chimney, and the compost may be further processed to for different composite organic fertilizer products.

Description

Technical field [0001] The invention relates to a process technology for comprehensive treatment of domestic garbage. It is aimed at the characteristics of "large volume, mixed packaging, low fuel value, and high organic matter" of urban domestic waste in China. Recyclables, fertilizers, and bricks can be selected from municipal solid waste through pre-sorting and process sorting. waste, incinerators, and landfills are treated separately. Background technique [0002] At present, the treatment methods of municipal solid waste in my country are as follows: one is simple landfill, which is banned by the country due to serious environmental pollution; the other is sanitary landfill, which has the disadvantages of large investment, waste of land resources, and harmless Recycling and reduction are not obvious, and resource utilization is also difficult to achieve, especially in areas where land is scarce such as coastal areas. The disadvantages are large investment, high operatin...
