Embodiment 1

[0061] A method for aerobic fermentation-sorting resource utilization of household garbage, including four unit processes of household garbage pretreatment, aerobic fermentation, sorting of materials after fermentation, and post-treatment of materials after sorting;

[0062] in:

[0063] The pre-treatment of domestic waste is to break the bags of domestic waste, discharge them, and send them to a fully enclosed aerobic fermentation warehouse for storage, and spray aerobic fermentation accelerators into the domestic waste at the same time as the discharge;

[0064] Aerobic fermentation adopts the method of active oxygen supply to realize static high-temperature aerobic fermentation of domestic waste piled in the aerobic fermentation bin, degrades, decomposes, stabilizes biomass organic matter, evaporates water, removes odor, and obtains loose The decomposed material after fermentation; after the landfill leachate produced in the aerobic fermentation process is collected, it is ...

Abstract

The invention discloses an aerobic fermentation-sorting recycling method for household garbage, and the aerobic fermentation-sorting recycling method comprising: spraying an aerobic fermentation promoter in the household garbage, carrying out aerobic fermentation, sorting fermented composted materials, and finally carrying out post-treatment on the sorted different materials. According to the process system disclosed by the invention, full-recycling of the household garbage is realized, totally-closed purification of the waste gas of a treatment field is realized, the wastewater is subjected to full-circulation treatment, the zero emission of the wastewater is realized, and the odor of the household garbage treatment field is eliminated; and an aerobic fermentation bin or the whole treatment field is in a semi-underground mode or even an all-underground mode, so that the situation that the garbage treatment field is dirty and smelly is completely changed.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment and resource utilization, and specifically relates to resource utilization of domestic waste. Background technique [0002] Municipal solid waste is solid waste with a large amount and a wide range. With the development of our country's economy and society and the higher and higher requirements for environmental quality, the amount of domestic waste is increasing, and its collection, transshipment, treatment and resource utilization are also more and more highly valued by governments at all levels and scientific and technological workers. [0003] There are many different combined processes for domestic waste disposal. The main early disposal technologies were composting, natural stockpiling, and landfill. However, with the emphasis on soil environment quality and agricultural food safety, municipal solid waste composting has gradually been eliminated due to the presence of toxic a...
