Method and device for mechanical sorting, recycling and resource utilization of landfill waste

Abstract

The invention discloses a mechanical sorting and recycling method and device for landfill waste. The mechanical sorting and recycling method comprises the following procedures: sorting the landfill waste; sorting separated soil and sand; recycling the sorted soil and sand; and recycling combustible waste. The mechanical sorting and recycling method disclosed by the invention is used for treating a large amount of landfill waste per day, and distinguishing and recycling various kinds of waste, an organic fertilizer can be prepared by recycling the soil and sand, fuel can be prepared by recycling the combustible waste, the energy regeneration of the waste can be fully achieved, resources are saved and the waste is utilized.

Description

technical field [0001] The invention relates to a method and device for sorting and reusing landfill waste, in particular to a method for mechanical sorting, processing, recycling and resource utilization of landfill waste. [0002] The present invention also relates to a landfill waste mechanical sorting, processing, recycling and resource utilization device used in the landfill waste mechanical sorting, processing, recycling and resource utilization method. Background technique [0003] Generally speaking, the waste buried in non-sanitary landfills or recycling landfills is mixed with recyclable combustible garbage, soil, sand, aggregates and other materials without sorting and directly landfilled, resulting in waste The high water content of the waste makes the load of the sorted waste also high, and the landfill waste contains a large amount of organic components such as kitchen waste and combustible substances such as plastics. Although it has the composting value of so...

[0003] Generally speaking, the waste buried in non-sanitary landfills or recycling landfills is mixed with recyclable combustible garbage, soil, sand, aggregates and other materials without sorting and directly landfilled, resulting in waste The high water content of the waste makes the load of the sorted waste also high, and the landfill waste contains a large amount of organic components such as kitchen waste and combustible substances such as plastics. Although it has the composting value of soil and sand, it is not Disposal of these garbage consumes too much waste treatment cost, and the landfill waste discharges landfill gas, stench, leachate, dioxin and other public hazards, causing serious soil, groundwater, and air pollution, which not only costs a huge amount every year budget, and waste valuable discarded resources without reuse
