Embodiment 1

[0023] The municipal solid waste treated by the invention comes from the Shijingshan garbage transfer station in Beijing, and the electronic waste, radioactive waste and infectious waste are separately treated before the treatment. Afterwards dispose of the trash according to the figure 1 The flow chart shown in the figure shows that the garbage first enters the mechanical tearing hook device, wherein the tearable hook components enter the discharge port and are collected for the preparation of biomass energy, while the non-tearable hook components enter the reciprocating puncture device, in which the punctureable kitchen waste is separated and collected for efficient composting, and the remaining non-punctureable waste components, mainly glass, bricks, muck, metal, ceramics, etc., are collected in the next process , for the preparation of porous insulation materials.

[0024] The implementation effect of the method of the invention is quite outstanding, and various valuable ...

Abstract

The invention provides a sorting treatment method of urban household garbage. The sorting treatment method comprises the following steps of (1) sorting components capable of being torn and hooked; (2) sorting components capable of being punctured; (3) taking garbage components which cannot be torn, hooked and punctured as main raw materials, adding a small quantity of texturizing agents, carrying out high-temperature sintering to prepare a porous thermal insulation material so as to achieve high-value utilization of the urban household garbage. According to the sorting treatment method, most urban living garbage can be taken as recyclable materials to be sorted and processed and can be subjected to resource utilization.

Description

technical field [0001] The invention relates to a method for sorting garbage, in particular to a method for sorting urban domestic garbage. Background technique [0002] With the improvement of the level of urbanization, the urban domestic garbage has surged, and the garbage treatment capacity is seriously insufficient. Some cities are facing the dilemma of "garbage siege". By the end of 2010, the annual domestic garbage removal volume in cities and counties across the country was 221 million tons, and the harmless disposal rate of domestic garbage was only 63.5%, of which 77.9% were in cities and 27.4% in counties. According to the "Twelfth Five-Year" National Urban Household Garbage Harmless Treatment Facilities Construction Plan", during the "Twelfth Five-Year Plan" period, it is planned to add 580,000 tons / day of domestic garbage innocuous treatment capacity, of which, the city's new capacity is 39.8 10,000 tons / day, and the new capacity of the county seat is 182,000 to...
