Problems solved by technology

Fertilizers made by composting are difficult to be accepted by the market due to poor fertilizer efficiency
Direct incineration is the most effective reduction method, but the moisture content of municipal solid waste in our country is high, direct incineration is very difficult, and it is easy to produce secondary pollution, which poses a great threat to the environment
Simply relying on a certain method to deal with garbage has many disadvantages

Embodiment Construction

[0020] The invention relates to a method for dehydrating organic matter in municipal solid waste, and its specific implementation steps are now described in conjunction with examples.

[0021] (1) Pre-sorting

[0022] Municipal solid waste is pre-sorted to sort out large combustibles, which are made into RDF, and the remainder enters the water separation device.

[0023] (2) Water selection

[0024] After the garbage is treated by the water separation device, the muck forms sludge in the water, and the bricks, tiles, stones and organic matter are separated. Sludge is put into degradation equipment for treatment, and bricks, tiles and stones are crushed and remade into building materials.

[0025] (3) winnowing

[0026] The organic matter selected by the water is separated by wind to separate the plastic and organic matter, and the plastic is made into plastic granules for sale, and the organic matter enters the degradation and reduction equipment.

[0027] (4) Degradation ...

Abstract

The invention relates to a novel method for comprehensive treatment of municipal solid wastes, comprising the following steps: separating different components in the municipal solid wastes by the procedures of preceding separation, water separation and wind separation, wherein bricks, tiles and stones are made into building materials, and plastics are granulated; and degrading and reducing organic matters and sludge, wherein the degraded organic matters are made into fertilizers or RDF. The invention fully conforms to the waste harmlessness, reduction and reclamation principle.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a new method for comprehensive treatment of municipal domestic garbage. Background technique [0002] At present, my country's municipal solid waste output is huge, but the processing capacity is far behind. Now the garbage landfills in many cities have been overloaded. At the same time, there are problems such as large land occupation, slow processing speed, and difficult leachate treatment. Fertilizers made by composting are difficult to be accepted by the market due to poor fertilizer efficiency. Direct incineration is the most effective reduction method, but the moisture content of municipal solid waste in our country is high, direct incineration is very difficult, and it is easy to produce secondary pollution, which poses a great threat to the environment. Simply relying on a certain method to deal with garbage has many disadvantages. The invention prov...
