Method for fully recycling municipal solid waste

Abstract

The invention discloses a method for fully recycling municipal solid waste. The method includes steps of garbage classification, garbage stabilization and catalytic cracking. The municipal solid waste is fully recovered and recycled. A harmless and resource-utilization treatment is achieved. Defects of long-period occupying land and polluting land resource in municipal solid waste incineration and landfill are avoided. Discharges of waste water, waste residue and waste gas are avoided. A Defect that landfill leachate and stink in the landfill seriously pollute the environment is avoided. A highest temperature during a production process is not higher than 180 DEG C and the method is free of generation of dioxin. A finished product can be a building product without generation of organic fertilizers. The defect that heavy metal in garbage compost harms human and livestock through food chain is avoided. All the environmental-protection indexes of the building product generated in the method reach requirements in national relative standard. The building product is huge in a market capacity. A problem that the building product is turned into new garbage since the product is lack of outlet is avoided.

Description

technical field [0001] The invention relates to a treatment method for urban garbage, in particular to a method for fully recycling urban domestic garbage. Background technique [0002] Due to the different economic development levels, living habits and consumption levels of municipal solid waste in various countries and regions of the world, there are great differences in the composition, shape, output characteristics and collection methods of domestic waste. The selected treatment technology and treatment The methods are also different, but in summary, there are three main types: incineration treatment method, landfill treatment method and composting treatment method. [0003] Disadvantages of incineration treatment method are: [0004] 1. Garbage incineration will cause secondary environmental hazards, especially the residue generated by incineration of garbage needs to be landfilled, which will occupy and pollute land resources for a long time; 2. Waste incineration equ...

Problems solved by technology

[0009] Aiming at the above-mentioned shortcomings, the present invention develops a method for recycling and reusing all urban garbage, mainly through physical crushing, biodegradation, polymer catalytic cracking, polymer polymerization and other methods to completely solve the problems of garbage harmlessness and garbage recycling. The problem is that the most environmentally friendly and economical garbage disposal method in the world is also the garbage disposal method most in line with China's national conditions. In order to realize the above-mentioned invention, the present invention adopts the following technical solutions to solve:
