Household garbage resource utilization treatment system

Abstract

The invention discloses a household garbage resource utilization treatment system. The system comprises a feeding subsystem, a first conveying mechanism, a sorting subsystem, a dry anaerobic fermentation subsystem, a high-calorific-value garbage pyrolysis subsystem and a plastic purification treatment subsystem. Through organic connection of the feeding subsystem, the first conveying mechanism, the sorting subsystem, the dry anaerobic fermentation subsystem, the high-calorific-value garbage pyrolysis subsystem and the plastic purification treatment subsystem, and the treatment system capable of combining multiple modes of biochemical reaction treatment, chemical reaction treatment, physical treatment, manual treatment and the like to comprehensively treat the household garbage so as to achieve recycling is formed; and due to the fact that landfill and incineration are reduced, and environmental pollution is reduced. The treatment system can make full use of organic fertilizer and biogas generated by garbage fermentation, waste heat and ash are generated by garbage pyrolysis, and in addition, plastic and leachate can be effectively recovered and utilized.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a domestic garbage resource utilization treatment system. 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. Household garbage forms s...
