황화수소취기의 생물학적 탈취 = Biological Deodorization of Hydrogen Sulfide Odor Gas

국문 초록 (Abstract)

본 실험은 黃化水素 취기를 생물학적 방법으로 제거하기 위하여 함수율, 용도, 영양염류 등을 변화시키면서 생물학적 최적조건을 발견한 다음 황화수소 입구농도를 100, 200, 300ppm, 표면적 부하를 40, 60, 80㎥/㎡·hr로 변화시켜 결과 다음과 같은 결론을 얻었다.
낙엽 Compost에 의한 생물학적 탈취는 가능하였으며, 낙엽 Compost를 이용하여 황화수소 취기의 탈취를 위한 생물학적 최적온도를 온도 20~30℃, 함수율 62±3%이었다.
표면적부하 40㎥/㎡·hr, 충진층 높이 50㎝에서 황화수소의 농도별 제거율은 100ppm에서 99.9%이상, 200ppm에서 99.2%, 300ppm에서는 84%였으며, 농도 200ppm, 충진층높이 90㎝에서 표면적 부하를 40, 60, 80㎥/㎡·hr로 변화시켰을 때 제거율은 각각 99.9%이상, 99.9%, 85%이었다.

The stydy was performed to remove hydrogen sulfide odor gas by the bio-filter. The optimum conditions of water contents, temp., and inorgarnic matters for this method was determined with a fixed concentration of hydrogen sulfide odor gas. Under this optimum conditions, the follwing results were obtained from various concentrations of hydrogen sulfide odor gas(100, 200, 300 ppm) and surface area load(40, 60, 80 ㎥/㎡·hr).
Biological deodorization by leaf compost was feasible and its optimum condition of temperature and water contents was 20~30℃ and 62土3%, respectively.
The rate of deordorization of hydrogen sulfide odor gag(100, 200, 300 ppm) with he height of packing material 50㎝ and surface area load 40 ㎥/㎡·hr was great than 99%, 99.2%, and 80%.
Similarly, the rate of deordorization of 200ppm of hydrogen sulfide odor gas at surface area load(40, 60, 80 ㎥/㎡·hr) with 90㎝ of the height of packing material was great than 99%, 99% and 85% respectively.
