Household garbage treating method

Abstract

The invention discloses a household garbage treating method and relates to the technical field of solid waste disposition. The household garbage treating method comprises the following steps that S1, household garbage is pretreated and divided into a first group of organic matters, a second group of organic matters and metal components, and the first group of organic matters is easier to decay than the second group of organic matters; S2, the second group of organic matters in the step S1 is subjected to thermal decomposition to generate thermolysis carbon powder and thermolysis oil, and the first group of organic matters in the step S1 is treated to generate decomposed materials and dried materials; and S3, the thermolysis carbon powder, the decomposed materials and the dried materials in the step S2 are sent into a gas furnace to be sintered to generate fuel gas, and meanwhile, inorganic matters in the materials is melted and sintered to form stable materials. The household garbage treating method has the beneficial effects that the household garbage can be decomposed into the fuel gas and the stable materials, so that the resource rate of the household garbage is improved. Compared with the prior art, landfilling and burning are not needed, a large amount of land does not need to be occupied, and burning pollution does not caused.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal, in particular to a domestic waste disposal method. Background technique [0002] With the rapid development of industrial civilization and the acceleration of urbanization in my country, the "quality" and quantity of domestic waste are changing. The proportion of organic matter (mainly composite materials) has increased, the proportion of inorganic matter (ash, soil, bricks, tiles, stones, etc.) has shown a downward trend, the proportion of recyclables has increased, the composition of combustibles has increased, and the calorific value has decreased. improved. [0003] At present, the treatment methods of domestic waste mainly include sanitary landfill, incineration, and composting. [0004] Domestic waste landfill has high requirements on site conditions, occupies a large area, requires a large amount of covering soil, has a long treatment cycle, is difficult to treat leachate, h...
