Abstract

The object of this study was to develop an advanced method for fluid flow and oxygen transmission and increase adhesive property of microorganism to waste plastic vessel that was made of microorganism media. Through lab scale experiments, we found the optimum packed media volume rate and method, and when the optimum condition was applied to pilot plant, we confirmed possibility of advanced treatment. The sewage that was used in the test was the sewage disposal facility established in C and K elementary schools, which utilized waste plastic media oxidation engineering method. Analysis showed that removal efficiency of organic matter, SS, T-N and T-P was very high, that the sewage disposal facility maintained stability of treatment when changeable load of raw sewage flowed in.

본 연구는 폐플라스틱용기 미디어 산화공법을 이용하여 유체 및 산소전달 효율 향상을 위한 개조 방법과 미생물 부착특성을 향상시키는 방법을 통하여 오수고도처리 함을 목적으로 하고 있다. 또한 실험실 규모의 실험에서 최적의 담체 층진율과 충진 방법을 도출함으로써, 실 규모 설비를 위한 최적 설계 인자와 운전인자를 확보하고, 오수의 고도처리를 위한 다양한 운전조건을 제공하여 폐플라스틱 용기를 미생물 담체로 사용할 경우 생물학적 반응에 의해서 분해 될 때 소비되는 산소량과 오수중에 현탁되어 있는 유, 무기성 부유물과 질소 제거가 이루어지는 메카니즘을 규명하고 오수 처리 효율 향상을 위한 운전인자 도출을 목표로 한다.
