Garbage recycling treatment process

Abstract

The invention discloses a garbage recycling treatment process which comprises the following steps: firstly collecting urban garbage, then transporting the collected garbage into a steam autoclave, and adding alkaline chemicals into the steam autoclave to form an alkaline high-pressure environment in the steam autoclave so as to neutralize acidic chemical substances in the garbage, so that the garbage is recycled; plastic components in the garbage are decomposed, microorganisms in the garbage are killed, odor is removed, moisture in the garbage is evaporated, then the garbage is taken out and dried, then the garbage is crushed to be convenient to sort, iron is sorted, non-ferrous metal is sorted through a non-ferrous metal sorting machine, and residual garbage obtained after sorting is completed is subjected to weight sorting. The method comprises the following steps: screening waste into gravel waste and combustible waste, adding additives such as a combustion improver into the combustible waste, mixing, then extruding to form an RDF fuel rod, mixing and grinding the gravel waste with lime and sand according to a certain proportion, and then carrying out extrusion forming to form a concrete product for secondary utilization.

Description

A waste recycling process technical field [0001] The present invention relates to the field of garbage disposal, particularly a process for recycling garbage. Background technique At any time social development, garbage gradually becomes a big problem for social development, and the current garbage disposal methods mainly include two One is the landfill method, which is low in cost, but requires a large amount of land, resulting in garbage polluting a large amount of land and water bodies, and cannot be reduced. The decomposed substances cannot be decomposed naturally under the landfill method. The other is the combustion method, which transports the waste to the power plant for combustion. Power generation has a good reduction effect and can bring certain economic effects, but direct combustion will produce toxic gases such as dioxins and furans. Moreover, the sand and gravel impurities in it cannot be burned and require secondary treatment. SUMMARY OF THE INVENTI...

Problems solved by technology

[0002] With the development of society at any time, garbage has gradually become a big problem for social development. There are two main methods of garbage disposal. One is landfill, which is low in cost, but requires a lot of land, causing garbage to pollute a lot of land and water, and is non-degradable. Substances cannot be decomposed naturally under the landfill method. The other method is the combustion method. The waste is transported to the power plant for combustion and power generation. The reduction effect is good and can bring certain economic effects, but direct combustion will produce dioxins , furan and other toxic gases, and the sand and gravel impurities in it cannot be burned, so secondary treatment is required
