PROCESSING METHOD OF FOOD WASTE LEACHATE CAPABLE OF IMPROVING EFFICIENCY OF OIL COLLECTION AND REDUCING WATER CONTENT OF SLUDGE

摘要

PURPOSE: A processing method of food waste leachate is provided to maximize separation efficiency of solids and oil recovery rates by installing a floating tank for oil separation and a floating separation tank for solid-liquid separation. CONSTITUTION: A processing method of food waste leachate includes the following: separating oil included in food waste leachate which is pre-processed with microbubbles dissolved in pressurized and pressed water; storing separated oil; separating the oil and water by heating the stored oil in an oil storage tank(50); adjusting pH of the food waste on which oil is removed; producing floc by rapidly and slowly coagulating the food waste leachate; separating the produced floc; and circulating the processed water on each step.
