다환 방향족 탄화수소로 오염된 준설 퇴적토의 생물정화를 위한 bioslurry reactor의 연속 운용조건 연구

Abstract

Conditions for successive operation of bioslurry reactor for bioremediation of dredged sediment contaminated by PAHs was established. Electron transport system activity during treatment was rapidly increased between 1 and 2 days and maintained when 1/5 or 1/10 of treated slurry was reused after 2 or 3 days of batch incubation. Degradation activity was also high after part of 2 or 3 days incubated slurry was reused. Therefore, 2 days of batch incubation and reuse of 1/10 volume treated slurry were determined for successive operation of slurry reactor. Concentration of mixed form cyclodextrin could be reduced to 1/2 after 2nd treatment.
