Treatment system and method for relatively concentrated in-situ treatment of organic wet garbage

Abstract

The invention relates to a treatment system and method for relatively concentrated in-situ treatment of organic wet garbage. The treatment system comprises a recycling system body, a gas treatment system body and a water treatment system body, and the recycling system body comprises an impurity removal device and a fermentation device; a material conveying outlet of the impurity removal device isconnected to a material conveying input of the fermentation device, a sewage conveying outlet of the fermentation device is connected to a sewage conveying inlet of the water treatment system body, and a gas conveying outlet of the fermentation device is connected to a gas conveying input of the gas treatment system body. According to the treatment system, in-situ environmental protection treatment is started to be conducted in a collection station, the treatment process of the wet garbage can be greatly simplified, and public resources such as land and highways are saved; odor and sewage generated in the treatment process of the wet garbage are conveyed to the gas treatment system body and the water treatment system body respectively to be subjected to purification treatment and then aredischarged after the standard is reached, so that environmental pollution caused in the treatment process of the wet garbage is avoided. In addition, the wet garbage is processed into fertilizer aftertreatment, so that recycling of resources is achieved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a system and a treatment method for relatively centralized and local treatment of organic wet garbage. Background technique [0002] As we all know, with the acceleration of urbanization and the increase of population, the output of garbage has increased sharply. 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 of the cities are surrounded by garbage, and 1 / 4 of the ...
