Domestic waste treatment technology

Abstract

The invention discloses a domestic waste treatment technology. Firstly, domestic waste is filtered, dried, sorted and torn and then subjected to comprehensive sorting, and domestic waste with the length being 40 mm or below, 40-80 mm and 80 mm or above is sorted out. In the waste with the length being 40 mm or below, compostable organic matter enters a reconciliation pond, shell objects enter a gasification and power generation workshop, and waste batteries enter a recycling factory to be recycled. In the domestic waste with the length being 40-80 mm, organic matter enters the reconciliation pond, glass, bricks and residue soil are used for producing bricks for buildings, and shoes serve as raw materials to enter the gasification and power generation workshop. In the waste with the length being 80 mm or above, plastic bags are used for oil refining in the oil refining technology, paper can be sold after being dried, flammable solid fuel and fabric enter the gasification and power generation workshop, and ABB / ABS / PVC materials serve as raw materials and are used for oil refining. According to the technology, secondary pollution is little, waste of land resources is reduced, and the resource recycling rate is greatly increased.

Description

technical field [0001] The invention relates to a domestic garbage treatment process, which belongs to the technical field of green environmental protection. Background technique [0002] With the acceleration of urbanization and the increase of population, the output of garbage has increased dramatically. According to statistics, in the 1980s, the national annual output of urban waste was about 115 million tons, and by the 1990s it had reached 143 million tons. At present, the domestic annual urban waste generation is about 180 million tons. It is predicted that by 2030, the total annual output of urban waste in China will reach 409 million tons. At present, the siege of urban domestic garbage in my country has become a thorny issue in urban construction and management. At present, among the more than 600 large and medium-sized cities in the country, 2 / 3 are surrounded by garbage, and 1 / 4 of the cities have no suitable places for stacking. Rubbish. At present, except for...
