A kitchen
garbage disposal method is characterized by including steps of 1, sterilizing, deodorizing, and adding hydrolyzing
protease into kitchen waste; 2, screening and crushing the kitchen garbage, sorting wastes such as glass and ceramics which cannot be disposed from deodorized garbage automatically, crushing the residual waste by a
crusher; 3, performing
solid and liquid separation, separating suspended matters with thickness of 2mm at least and solids and squeezing to dewater to form a tailing product, and discharging
oil water into an oil and water separator; 4, performing oil and water separation to separate heavy oil, light oil,
sewage and
sludge and the like in waste water of the kitchen garbage, feeding the separated oil,
sewage and
sludge into an
oil storage barrel, a
sewage treatment device and a
sludge collection
barrel respectively; 5, purifying sewage by details of feeding the separated sewage into a sewage purifying
system which is provided with air flotation and
reverse osmosis devices; and 6, treating the tailing
solid products by details of hydrolyzing the tailing
solid subcritically, subjecting dynamic
fermentation to the tailing solid products for two to three days after subcritical
hydrolysis treatment, and finally obtaining an
organism modifier for soil.
