Method and system for completely recycling household garbage

Abstract

The invention discloses a method and a system for completely recycling household garbage. The method comprises a garbage unloading, temporary storage and feeding treatment process, a garbage sorting treatment process, an organic biomass hydrolysis and thorough decomposition treatment process, an organic fertilizer preparation treatment process, a reclaimed plastic raw material preparation treatment process, a combustible treatment, pyrolysis and gasification treatment process, an inorganic salt sintered ceramsite preparation treatment process, a pollution gas treatment process, a hydrolysis concentrated water and garbage leachate treatment process, and a hazardous waste treatment process, wherein the garbage sorting treatment process is used for classifying the garbage into organic biomass kitchen waste components, waste plastic components, combustible components, inorganic components and hazardous wastes; the pollution gas treatment process is used for recovering and treating pollution gases released in the other processes; the hydrolysis concentrated water and garbage leachate treatment process is used for recovering and treating waste water generated in the other processes; and the hazardous waste treatment process is used for treating the hazardous wastes. The method and the system, which are disclosed by the invention, are capable of realizing zero discharge of a garbage disposal process, meet environmental protection requirements, and also create a new means for the field of social renewable resources.

Description

technical field [0001] The invention relates to a method and a device for treating garbage, in particular to a method and a device for treating domestic garbage. Background technique [0002] Usually the so-called domestic waste refers to the waste generated in people's daily life, which is generally mixed waste with extremely complex components. Economically developed regions have a lot of waste packaging such as plastic and paper; fourth, there is a lot of construction waste such as bricks, glass, and metal in economically backward regions; fifth, there is a lot of furnace ash in winter in cold regions. [0003] Commonly used domestic waste treatment methods are mainly three technologies: landfill, incineration and waste composting. The serious defects of these three waste treatment technologies are mainly that the secondary pollution is serious during the treatment process, the degree of reduction is low, and the legacy hazards are huge. and other major hidden dangers,...

Problems solved by technology

[0003] Commonly used domestic waste treatment methods are mainly three technologies: landfill, incineration and waste composting. The serious defects of these three waste treatment technologies are mainly that the secondary pollution is serious during the treatment process, the degree of reduction is low, and the legacy hazards are huge. and other major hidden dangers, especially the low level of resource utilization of waste, which is difficult to meet the needs of social and economic development

[0004] At present, the environmental problems caused by domestic garbage are very serious, and most cities are caught in the tense situation of garbage siege. However, the existing garbage disposal methods are not perfect, and cannot meet the requirements of thorough purification of household garbage and elimination of environmental pollution. Technical means to solve the problem of domestic waste pollution
