Abstract

A pilot-plant biofilter ($1750\;m\;W{\times}2750\;mm\;L{\times}2000\;mm\;H$) packed with polyurethane foam ($20\;m\;W{\times}20\;mm\;L{\times}20\;mm\;H$) was installed in an pharmaceutical plant emitting gas streams containing n-hexane and alcohols. The biofilter was successfully operated for 74 days under highly fluctuating incoming concentrations at a residence time of 12.8-24.8 sec. Alcohols and n-hexane were removed by more than 90% from 5 and 20 days after start up, respectively. Malodor was also removed more than 95% from 20 days after start up.

본 연구는 폴리우레탄을 담체로 사용하고 자동교반장치가 장착된 pilot-scale의 바이오필터 (1$1750\;m\;W{\times}2750\;mm\;L{\times}2000\;mm\;H$)를 제약공정 현장에 설치하여 74일간 막힘현상 등 제반 문제없이 성공적으로 가동하였으며 제약공정에서 발생하는 가스에 함유된 핵산과 알코올류로 구성된 휘발성 유기 물질 (VOC)과 악취를 효율적으로 제거하였다. VOC 유입농도의 변화가 비교적 심한 조건임에도 불구하고 체류시간 $12.8{\sim}24.8$초의 가스공급조건에서 알코올류는 가동 5일후부터 90% 이상 100%에 근접하는 제거율을 보였고, n-핵산은 16일정도의 적응기를 지나서 평균 89%가 제거되었고 그 후 더욱 제거율이 증가하였다. 악취 또한 20일 이후부터는 95% 전후한 높은 제거효율을 나타내었다. 향후 적응기간 단축 등의 내용을 다소 보완하여 현장에 실규모 (full scale)로 적응이 가능할 것으로 사료된다.
