Abstract
Rotating Biological Contactor (RBC) was tested for the treatment of artificial rearing water in n simulated aquaculture system. Performance of RBC on the removal of TAN and COD was evaluated by controlling hydraulic residence time (HRT). As HRT of RBC was increased, TAN removal rate ana removal efficiency of RBC and TAN concentration of rearing water were increased, but COD removal rate was decreased. Total alkalinity consumption rate was increased by increasing HRT of RBC. Ratio between total alkalinity consumption rate and TAN removal rate was 7.73. HRT for maintaining lowest TAN and COD concentration of artificial rearing water was 14,6 minutes and at that condition TAN and COD concentration of the water was 1.28 and
본 연구에서는 양식장에서 많이 이용되고 있는 회전원판 반응기를 모의 순환 여과식 양어장에 적용하여 인공 양식수 처리 실험을 행하면서 어류의 최적 사육환경을 유지할 수 있는 운전인자를 도출하고자 하였다. 회전원판 반응기는 수리학적 체류시간이 감소하는 부하변동에대해
