알칼리 및 오존 병합 전처리를 이용한 슬러지 감량화 공정의 실증플랜트 연구 = Full Scale Study on the Sludge Reduction Process Using Alkali and Ozone Pretreatment

다국어 초록 (Multilingual Abstract)

Full scale of sludge reduction process(P release reactor-combined use of alkali and ozone pretreatment-fermentation-crystallization) with KSMBR process was operated for 3 months to evaluate the reduction efficiency and solubility of sludge and the effluent water quality of KSMBR process. The average efficiencies of sludge reduction and solubility were 35% and 20.4%, respectively for 3 months. By crystallization, phosphorus was successfully removed from the solubilized sludge as an apatite and its average removal efficiency was 80.2%. When solubilzed sludge was appled into the anaerobic reactor of KSMBR process as an external carbon source, the average removal efficiency of the total phosphorus was improved up to 40%. Therefore, sludge reduction process proposed is thought to be applied onto phosphorus recovery and an external carbon source as well as sludge reduction.
