The invention discloses a kitchen garbage treatment and comprehensive utilization
system and a method thereof. The kitchen garbage treatment and comprehensive utilization
system comprises a kitchen garbage grinder, a kitchen garbage liquid collecting
system, a
solid-liquid separator, a
solid packing
machine, a sterilizer, an oil-water separator, a
grease storage tank and a waste
water storage tank. Firstly, the kitchen garbage is ground by the grinder; then, kitchen garbage liquid is input to the kitchen garbage liquid collecting system and then pumped into the
solid-liquid separator for solid-liquid separation, so as to separate the kitchen garbage liquid into solid kitchen garbage and liquid kitchen garbage; the solid kitchen garbage is packaged and sterilized and then is secondarily processed to be used as a
raw material for producing feed or organic fertilizers; and the liquid kitchen garbage is separated into
grease and waste water through the oil-water separator, the
grease is collected in the grease
storage tank for recycling, and the waste water is discharged into a
municipal sewage pipe network. The kitchen garbage treatment and comprehensive utilization system and the method thereof in the invention not only can eliminate the cost of packaging bags and
pollution thereof but also reduce the transportation amount of kitchen garbage by 70-90%; and at present, the comprehensive recycling of kitchen garbage resources can be realized, and the environmental
pollution caused by untimely garbage transportation and the
plastic pollution caused by kitchen garbage packaging can further be eliminated.
