Abstract

The invention relates to an organic waste dry anaerobic high-temperature fermentation system and a fermentation process. The fermentation system comprises a feeding system (1), a dry anaerobic fermentation tank (2) with an agitating system (3), a heat preservation and heating system (4), a biogas slurry and biogas residue treatment system (5), an exhaust system (6) and a control system. The organic waste dry anaerobic high-temperature fermentation system and the fermentation process have the beneficial effects that harmless treatment, reduction treatment and resource treatment can be carried out on domestic organic wastes, so that the cyclic utilization of the wastes is realized; and moreover, the treatment efficiency is high, and the energy consumption and the treatment cost are low.

Description

technical field [0001] The invention relates to the technical field of processing organic waste such as organic parts in domestic waste, kitchen waste, greening waste, crop straw, livestock manure, septic tank bottom sludge, activated sludge, water hyacinth, blue algae and the like. Background technique [0002] At present, the organic components in domestic waste in our country are constantly increasing. Compared with developed countries, the organic components in domestic waste in my country are very different. The content of paper is low, the content of kitchen waste and green waste is high, and the moisture content of kitchen waste is high. The moisture content is 70% to 80%, and the moisture content of melon skin can be as high as 95%. Incineration of garbage has the advantages of recovering heat energy and reducing the amount of garbage most thoroughly. After incineration, the volume of garbage can be reduced by 80% to 95%. However, organic garbage has high moisture co...
