The present invention relates to a food waste leachate treatment system which can minimize the amount of sludge generated and which can significantly reduce operating costs and energy consumption. The present invention provides a food waste leachate treatment apparatus, comprising: a front floatation tank which receives food waste leachate, and eliminates scum, generated by combination of fat and suspended solids, from the food waste leachate; an acid fermentation tank which is installed behind the floatation tank, receives liquid treatment water discharged from the floatation tank and ferments organic material in acid, and includes a bubble introduction part in which microbubbles are fed at a lower portion thereof, a reaction part which includes a vertical cylinder in which waste water, agitated only by the entering microbubbles, is fermented in acid, and a scum separator which eliminates scum formed in an upper portion of the reaction part; a rear floatation tank which is installed behind the acid fermentation tank, receives the treatment water discharged from the acid fermentation tank, and additionally separates and eliminates scum; a microbubble feeder which feeds microbubbles to the bubble introduction part below the acid fermentation tank; and an anaerobic digestion tank which receives the liquid treatment water from which the scum generated in the acid fermentation tank has been eliminated, and subjects the liquid treatment water to anaerobic fermentation. |
