하수슬러지 가용화, 감량화를 위한 화학적 전처리 방법별 특성평가 = Evaluation on the Characteristics for Biosolid Solubilization and Reduction by Chemical Pre-treatment Methods

다국어 초록 (Multilingual Abstract)

In order to evaluate the independent and incorporative use of pre-treatment on solubilization and reduction efficiency and applicability as an external carbon source for denitrification, various pre-treatment methods were studied. Among the various pre -treatments, alkali-ozone pre-treatment showed the highest SDNRs, RBDCOD fraction and sludge reducing rate in this study. As compare with control, the concentration of SCOD was increased by approximately 77, 98 and 115 times and the SDNRs by SCOD generated from alkali-ozone pre-treatment were 4.5, 5.4 and 6.0 mg NO₃-N/g MLVSSㆍhr and sludge reducing rate were 0.4 mgSS/mgSS, 0.49 mgSS/mgSS and 0.52 mgSS/mgSS respectively. Consequently, the incorporative use of pre-treatments was much more effective than other independent use of pre-treatment to solubilization, the use of external carbon source for denitrification and reduction.
