Abstract
본 연구에서는 생물학적 공정을 사용하여 황화수소를 제거하는데 있어 망상구조의 폴리우레탄 담체의 바이오필터 충진물로서의 특성을 유입가스농도와 유입가스량의 두 변수를 대상으로 조사하였다. 실험결과 망상구조의 폴리우레탄 담체를 적용한 바이오필터의 황화수소 최대제거용량은 488.3 g-H2S/m3·h이었으며, 추정된 임계부하속도는 330.1 g-H2S/m3·h이었다. 본 연구의 결과 망상구조의 폴리우레탄 담체를 황화수소의 생물학적 처리를 위한 바이오필터의 담체로서 적용가능성을 확인하였다.
In order to assess its capability as biofilter bed material under variable conditions of two parameters (inlet gas concentration and inlet gas flow rate), reticulated polyurethan was applied to remove hydrogen sulfide via a biological process. We detected a maximal elimination capacity (critical loading rate) of 488.3 (330.1) g-H2S/m3·hr, when reticulated polyurethane was employed as supporting material of biofilter. This study show that the application of reticulated polyurethane carrier might be a favorable choice as a packing material in biofilter for the biological removal of hydrogen sulfide.
