Title:
SYSTEM AND METHOD FOR COOPERATIVELY TREATING KITCHEN WASTE IN GARBAGE INCINERATION PLANT
Document Type and Number:
WIPO Patent Application WO/2022/032481
Kind Code:
A1
Abstract:
Disclosed are a system and a method for cooperatively treating kitchen waste in a garbage incineration plant. The system comprises a garbage pool, a three-phase separation device and a garbage incineration and power generation system, and further comprises a garbage leachate treatment system and a back-spraying device which work synergistically. Solid residue resulting from leachate of the garbage pool passing through the three-phase separation device enters the garbage pool; waste water is treated in two paths, waste water in a first path is treated by the garbage leachate treatment system, and waste water in a second path is sprayed back to an incinerator of the garbage incineration power generation system by means of the back-spraying device; and crude grease resulting from kitchen garbage and household garbage passing through the three-phase separation device is further purified or sold. According to a flow direction of the waste water, for the treatment of the waste water in the first path, a coagulation device and an air floatation device are sequentially arranged before the position where the waste water enters the garbage leachate treatment system; and for the treatment of the waste water in the second path, a homogeneous emulsification device and a filtering and impurity removing device are further arranged in front of the back-spraying device. The system can mainly solve the problem of a high amount of grease in waste water treatment during a synergistic treatment process of kitchen waste.
