The present invention relates to a food waste leachate treatment system including: a leachate storage tank in which food waste leachate is collected a solid-liquid separator performing solid-liquid separation on the leachate supplied from the leachate storage tank a neutralization device performing a neutralization treatment on treated water separated by the solid-liquid separator a thermal hydrolysis device hydrolyzing sludge by applying heat to the food waste leachate a boiler supplying heat required for the thermal hydrolysis device a heat exchanger cooling the treated water discharged from the thermal hydrolysis device a pressurized floatation tank causing to float and removing condensate containing distillate of the treated water thermally hydrolyzed by the thermal hydrolysis device an anaerobic digestion tank performing methane fermentation on the treated water discharged from the pressurized floatation tank an ammoniacal nitrogen removing device having an anaerobic reaction unit where the treated water from the anaerobic digestion tank flows in and is stored and an anaerobic reaction occurs, a bubble generation unit disposed at a lower end of the anaerobic reaction unit and supplying microbubbles to the treated water, and an ammonia discharge unit where the bubbles generated by the bubble generation unit stir the treated water stored in a storage unit, decreases solubility of ammonia dissolved in the treated water, and discharges the treated water to the outside a dehumidifier removing humidity from the gas discharged from the anaerobic digestion tank and a deodorizer provided with activated carbon for deodorization of the gas from which the humidity is removed by the dehumidifier.COPYRIGHT KIPO 2016본 발명은 음식물 쓰레기 탈리여액을 모아두는 탈리여액저류조 상기 탈리여액저류조로부터 공급된 탈리여액을 고액분리하는 고액분리기 상기 고액분리기에서 분리된 처리수를 중화처리하는 중화장치 음식물 쓰레기 탈리여액에 열을 가하여 슬러지를 가용화하는 열가용화장치 상기 열가용화 장치에 필요한 열을 공급하는 보일러 상기 열가용화장치에서 배출되는 처리수를 냉각하는 열교환기 상기 열가용화장치에서 열가용화 처리된 처리수의 유분을 포함하는 응집물을 부상시켜 제거하는 가압부상조 상기 가압부상
