하천오염분석에 관한 연구
A Study on the Stream Pollution Analysis
초록
Warburg 실험장치와 회분식 폭기조를 사용하여 하천의 저질을 대상으로 징생물에 의한 분해가능물질의 처리정도와 화학적산소요구량, 총유기성 및 암모니아성 질소, 총유기탄소의 변화를 측정하였다. Warburg 실험장치는 빛을 차단하고 2
Bottom sediment-river water samples were studied to determine the extent of biodegradable matter and to examine the reduction of COD, TKN and TOC by using of warburg and aerated batch reactor. Warburg studies were conducted to study the Oxygen Uptake Rates, Reaction Rate Constants and CBOD. Bacth reator studies were conducted to determine the reduction of COD, TKN and TOC. Results from the batch recator study indicate high concentration of COD in samples. Less than 10 precent of the Organic Carbon was found to be biodegradable in 48 hours of Warburg experiment. Appreciable Immediate Oxygen Demand of sediments suggests that dredging of the river bottom is likely to deplete dissolved significantly in the river water.
