Propagate, the risk of food security be present；By kitchen garbage together with other municipal refuses during burning electricity generation, because kitchen garbage contains
Water is high, caloric value is low, can not only meet the caloric value requirement of burning electricity generation, be also easy to cause incinerator burning insufficient and
Bioxin is produced, air is seriously polluted, the life and health of people is constituted a threat to；By kitchen garbage together with other municipal refuses
The method of landfill does not only take up large amount of land resources, and serious secondary pollution is caused to soil and underground water, also results in big
The waste of the organic matter of amount；The method of Anaerobic Treatment is carried out to kitchen garbage can change into kitchen garbage biogas, and biogas
It is a kind of regenerative resource of cleaning, can be used for generating electricity and as fuel.Therefore, kitchen garbage Anaerobic Treatment is that one kind has much
The Food waste treatment method of development prospect.
In process of the present invention is realized, inventor has found that correlation technique has problems with：At anaerobic fermentation of kitchen waste
Time-consuming for reason, less efficient, easily causes kitchen garbage and overstocks excessively.How anaerobism hair more efficiently to be carried out to kitchen garbage
Ferment processing is current urgent problem to be solved.

Alternatively, it is described by the temperature for reaching the material for carrying out optimal anaerobic fermentation reaction condition at 30 DEG C -35 DEG C
The lower reaction for carrying out anaerobic fermentation and producing biogas, obtains biogas and is specially the step of biogas slurry：
The reaction time that the anaerobic fermentation produces the reaction of biogas is 1-2 days.
Alternatively, it is described by kitchen garbage raw material carry out ball-milling treatment, obtain pasty material the step of in, the diploma of acquisition
The particle of material is less than 3mm.
Alternatively, the slurry to after the oil removing carry out solid content be 5%-8%, C/N ratio be 20-30, temperature be
The adjustment of 40 DEG C of -60 DEG C of grades, acquisition the step of reaching the material for carrying out optimal anaerobic fermentation reaction condition be specially：
The slurry to after the oil removing carry out solid content be 5%-8%, C/N ratio be 20-30, temperature be 40 DEG C -60
