Abstract

This study was tested to evaluate the effect of the six different combinations of microbubble, catalyst, and air as oxidant on the sludge and organic matter reduction. When all of microbubbles and catalyst, and an oxidizing agent (under Conditions 1) such as air were used, the sludge was removed more than 99%, and TCOD and SCOD removal was 58% and 13%, respectively. This result was the highest value of six conditions. In the following order, the sludge reduction of the microbubbles with air (Condition 2) and catalyst with air (condition 4) was 95% and 93.1%, respectively. TCOD removal was found to be each 53% and 47%. When the microbubbles were used with oxidant like air, the removal of sludge and organic matter was high. All of these values were higher than that of using only microbubbles and catalyst without air. In the microbubbles and catalyst react under air supply condition, OH-radicals were generated in the reaction process. These OH-radicals in the reaction process decomposed the pollutants by the strong oxidizing power. In all conditions with air, the sludge reduction was high removal rate more than 93% and TCOD removal was over 47%.

마이크로버블과 촉매 그리고 산화제(공기)의 적용에 따라 6개의 서로 다른 조건으로 구분하여 가축분뇨의 슬러지 감량과 유기오염물질의 저감 효과를 알아보았다. 마이크로버블과 촉매, 그리고 산화제 모두 사용 하였을 때(조건1), 슬러지는 99% 이상 제거 되었으며, TCOD와 SCOD는 각각 58%와 13% 제거되었으며, 모든 조건에서 가장 높은 저감 효과를 나타냈다. 산화제를 공급하면서 마이크로버블(조건2)과 촉매(조건 4)를 사용하였을때, 슬러지 감량은 95%와 93.1%, TCOD의 감량은 53%와 47%로 나타났다. 산화제(공기)를 공급할 때는 마이크로버블의 저감효과가 촉매보다는 더 큰 것으로 나타났다. 마이크로버블과 촉매 반응은 산화제와 함께 반응 과정 중에 OH-라디칼이 생성되고, OH-라디칼의 강한 산화력에 의해 오염물질이 분해되는 것이다. 산화제와 함께 마이크로버블과 촉매에 의한 슬러지 감량 효과는 모두 93% 이상이었으며, TCOD의 감량은 47% 이상이었다.
