Abstract

The degradation of methylethylkeone(MEK) was investigated by the continuous single module photocatalytic reactor. Operational conditions were initial concentration of MEK, intensity of photon flux, and activity change according to the long time operation. The photocatalytic degradation was decreased with the increase of MEK concentration, and the degree of decrease was larger at higher flow rate. Removal efficiency of photocatalytic reactor was decreased with the increase of reactor diameter and lamp wavelength under the same residence time condition. Continuous single module photocatalytic reactor was successfully operated without any activity drop during 120hrs operation.

methylethylketone(MEK)의 광분해 특성을 연속식 단일관형태의 광촉매반응기를 이용하여 연구하였다. 연속식 광촉매반응기에 적용된 주요 반응변수는 MEK의 초기농도, 광세기, 장기운전의 영향이었다. MEK의 주입농도가 증가할수록 광분해 효율은 감소하였으며, 광분해 감소의 폭은 높은 유속에서 더욱 두드러졌다. 동일한 체류시간의 조건에서 광반응기의 직경과 UV램프의 파장이 증가할수록 MEK제거효율은 감소하였다. 연속식 광촉매반응기를 120시간 연속적으로 운전하여도 MEK 제거효율에서의 감소는 없었다.
