Abstract
This study developed composition-plastic media with woodchips and plastic as main materials, and examined the performance of media. Compared to the existing commercial media, the media had similar performance in removal efficiency and microbes attaching characteristic, and was evaluated that they are distinguished from economic side. Performance test of media was conducted to examine the removal capacity of toluene and hydrogen sulfide in a gas stream by using a lab-scale biotrickling filter systems packed with them. At a volumetric loading of $1.5\;m^3/hr$ with inlet concentration 260 ppm and empty bed residence time (EBRT) 42s, the toluene removal efficiency was shown over 90%, and the maximum elimination capacity of toluene in the biotrickling filter was $77g/m^3{\cdot}hr$. Effective co-treatments of $H_2S$ and Toluene were observed in the lab-scale biotrickling filters. The maximum elimination capacity of $H_2S$ was $100\;g-S/m^3{\cdot}hr$. Up to 100 ppm, the concentration of $H_2S$ did not have an effect on toluene removal efficiency, but the removal efficiency of toluene decreased with increasing inlet $H_2S$ concentration.

본 연구에서는 플라스틱과 Woodchip을 주원료로 하여 복합플라스틱계 담체를 개발하고 성능평가를 실시하였다. 개발담체는 기존상용화 담체에 비하여 처리효율 및 미생물 부착성 등은 유사하였으나, 경제적인 측면에서 우수한 것으로 평가되었다. 담체의 성능평가는 Lab scale의 바이오트리클링필터에 개발담체를 충진하여 톨루엔과 황화수소를 대상으로 제거효율 및 운전인자 등을 평가하였다. 본 연구에서 톨루엔 제거효율은 가스유입량 $1.5\;m^3/hr$, 유입농도 260ppm, 공탑체류시간 42s 운전조건에서 90% 이상으로 높게 나타내었으며, 톨루엔 최대제거능은 $77\;g/m^3{\cdot}hr$이었다. 황화수소와 톨루엔 동시제거 실험에서는 $H_2S$와 톨루엔이 효과적으로 제거되었다. $H_2S$의 최대제거능은 $100\;g-S/m^3{\cdot}hr$이었으며, $H_2S$ 농도가 100 ppm까지는 톨루엔제거에 영향을 주지 않았으나 $H_2S$ 농도가 증가함에 따라 톨루엔 제거효율은 감소되었다.
