Embodiment Construction

[0023] The present invention will be further described now in conjunction with accompanying drawing.

[0024] Such as figure 1 As shown, the organic waste is collected by a special collection vehicle, sent to the crusher through a spiral conveying pipe for crushing, and the organic waste is crushed into a slurry.

[0025] Pass the slurry into the primary screening device for primary screening, wash the slurry with flushing water to make a slurry, and use forced mechanical separation to separate the coarse materials in the slurry such as glass, ceramics, shells, bones and other hard materials The solid organic slag in the hard objects and light flexible debris is manually sorted out, and the solid organic slag is re-crushed to make a slurry, and the non-organic slag is left. of the remnants.

[0026] The slurry after primary screening is screened to remove hard gravel, metal slag, finely divided plastics, fibers and other residues in the slurry, and then the slurry after fine...

Abstract

The invention discloses an organic garbage disposal process which comprises the following disposal steps: crushing, preliminary screening, fine screening, biological oil refining, microbial decomposition, microbial anaerobic fermentation, sewage treatment, desulfurization, high-temperature steam heating and the like. The organic herbage disposal process disclosed by the invention has the advantages that aerobic-facultative decomposition and anaerobic fermentation are combined, thereby radically solving the problem about water pollution caused by organic garbage landfill and the problem about air pollution caused by organic garbage incineration; no harmful substance is generated in the whole organic herbage disposal process, thereby achieving the harmlessness; biological oil separated from organic garbage can be applied to a chemical enterprise, methane generated from the fermentation is extensive in use, clean and environmentally friendly, and elemental sulfur recovered through a sulfur recovery process is high in purity, thereby achieving the recycling effect; by adoption of the aerobic-facultative decomposition process, the weight of the organic garbage can be reduced by 95% or above; and compared with a conventional organic anaerobic composting process, the organic garbage disposal process has the advantages that the efficiency is higher, the weight of the organic garbage is reduced more obviously, and the weight reduction is achieved.

Description

technical field [0001] The invention relates to garbage treatment technology, in particular to an organic garbage treatment process. Background technique [0002] Organic waste mainly refers to kitchen waste, agricultural waste and other waste containing a large amount of perishable and smelly organic matter, mainly including oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones and waste tableware, plastics, paper towels, etc. mixture of substances. The amount of food waste in my country is very large, and it is showing a rapid upward trend. Improper disposal of organic waste will cause harm in the following aspects: affect the city's appearance and living environment, affect people's visual and olfactory comfort and living hygiene, breed bacteria and other microorganisms, pollute surface and groundwater; feed organic waste as feed Improper handling of impurities and foreign objects (such as gravel, iron wire, shells, bones, toothpicks, plastics, etc.) insi...
