Abstract

This research was performed for developing of biological treatment process of odor gas such as MEK, $H_2S$, and toluene, which was generated from the food waste recycling process. To establish the operational conditions of odor gas removal by small-scale biofiltration equipment, it was continuously operated by using toluene as a treating odor object. When the odor treating microorganisms were adhered to fibril form biofilter, high removal efficiency over $93\%$ was obtained by biofilm formation. At 400 ppm of inlet odor gas concentration and 10 sec of retention time, the removal efficiency was $76\%$ and $93\%$ in 1 st stage reactor and End stage reactor, respectively. However, the removal efficiency remained over $97\%$ at the operational conditions above 15 sec of retention time.

섬유상 담체를 이용한 2단 소형 바이오필터를 이용한 악취가스 처리공정의 운전조건을 확립하기 위하여 BTX를 처리대상 물질로 바이오필터를 연속적으로 운전하여 섬유상 바이오필터 담체에 악취가스 처리용 미생물을 부착시킨 결과 우수한 부착된 생물막을 형성하여 높은 처리효율 $93\%$를 얻을 수 있었다. 또한, 악취 유입 농도 400 ppm 미만에서 체류시간 10 sec일 때 1단 반응기에서 $76\%$ 정도 제거율을 보이다가 2단 반응기에서 약 $93\%$의 제거율을 나타내었다. 그러나 체류시간이 15 sec 이상인 경우에는 제거효율이 $97\%$ 이상 유지되었다.
