Embodiment Construction

[0034] figure 2 Among them, the garbage enters the chain plate conveyor (1) and is transported to the hand-selected belt conveyor (2), and is manually sorted to remove dangerous goods and large-volume objects mixed in the garbage, and the garbage after primary selection is transported to the disintegrator (3) to break up, and then transported to the drum screening machine (9) after the magnetic metal is separated by the belt conveyor (4) through the magnetic separator (8). The garbage of 70mm is transported to the vibrating screening machine (11) by the belt conveyor (10) again. The screen hole of the vibrating screening machine is 20mm, and the garbage smaller than 20mm is separated by the belt conveyor (13) through the magnetic separator (14). The metal is transported to the belt conveyor (16) and enters the storage hopper (18), and the garbage larger than 20mm is transported to the belt conveyor (17) after the magnetic metal is separated by the belt conveyor (12) through t...

Abstract

The invention discloses a domestic waste processing method which integrates efficient separation and recovery of the resources in municipal domestic waste, sanitary landfill, incineration and composting treatment into a whole, wherein, firstly objects with larger volumes in the waste are preliminarily separated, a wind sorting machine separates films and papers in the waste from the objects with large specific gravity, a magnetic separator recycles magnetic metals in the waste, a roller screening machine is used for separating plastics and papers which have larger volumes from food, sediment and vert, a shuffle grader separates such organic compounds as the food, the vert and the like, from the sediment, a manual separation system separates and classifies waste papers and the plastics in the waste, a compressing packager is used for packing the papers and the plastics after separation, a waste press-mounting machine is used for compressing the waste, the organic compounds and the vert after classification are treated by composting, inorganic matters are sanitarily land-filled, the waste papers, the plastics and the metal resources are recycled. The method of the invention realizes the highly efficient recovery of recoverable resources in the waste, thus basically solving the disadvantages in sanitary landfill, incineration and composting treatment methods.

Description

technical field [0001] The invention relates to a comprehensive treatment method for efficient classification and recycling of resources (plastics, paper, metals) in municipal solid waste, organic matter recycling, composting or incineration, and inorganic matter landfilling. Background technique [0002] According to inventor's understanding, at present my country's municipal solid waste treatment technology is summed up, and sanitary landfill method, composting method, incineration method are arranged. Its main advantages and disadvantages are as follows: [0003] 1. Sanitary landfill method [0004] Landfill generally includes open-air stacking, natural ditch filling and pit filling. It is a breeding ground for diseases, insects and germs, which not only endangers human health, but also pollutes air and water sources and affects the image of the city. Sanitary landfill is to fill the garbage in a suitable place at a certain height, add covering materials (to prevent ra...
