초록

공기부상식 포말분리기를 제작하여 해수 속의 단백질, 부유 고형물, 화학적 산소 요구량, 탁도, 암모니아성 질소와 같은 양식 폐기물의 연속 제거운전을 수행하여 수력학적 체류시간의 변화에 따른 양식 폐기물의 제거 특성을 검토하였으며 포말분리기의 용존산소 공급 능력을 검토하였다. 수력학적 체류시간의 증가에 따라 단백질 및 각 양식폐기물의 제거율은 증가하였다. 최고의 단백질 제거속도를 얻기 위한 수력학적 체류시간은 0.48분이었으며 이때의 단백질 제거속도는 10.25 g/㎥·min이었다. 수력학적 체류시간의 변화에 따른 총 부유 고형물, 화학적 산소 요구량과 탁도의 제거속도 변화는 단백질과 유사한 경향을 나타내었으며 최고의 단백질 제거속도를 얻기 위한 수력학적 체류시간에서 총괄 용존산소 전달계수가 가장 높은 것으로 나타났다.

Experimental investigations on the effect of the hydraulic residence time(HRT) for the removal of aquacultural waste, such as protein, total suspended solids(TSS), chemical oxygen demand(COD), turbidity and total ammonia nitrogen(TAN) from sea water were carried out by using foam separator. The foam separator as an aerator was also evaluated for increasing dissolved oxygen concentration. The increase in hydraulic residence time increased the removal efficiencies of aquacultural waste. Optimum hydraulic residence time was 0.48 min and the highest protein removal rate was 10.25 g/m(3) min. The changes of removal rates and efficiencies of TSS, COD and turbidity were similar to proteins. The hydraulic residence time for highest overall oxygen mass transfer coefficient was the optimum condition for the highest protein removal rate.
