Abstract
Linear alkylbenzene sulfonate(LAS)를 함유한 산업 페수를 효율적으로 처리할 수 있는 생물공정을 연구하였다. 활성오니의 적응실험을 통하여 확보한 LAS 분해 미생물은 매우 느린 성장 속도를 갖는 반면 비교적 고농도에서 기질저해작용을 받았다. 유동층 생물반응기에서의 약 15일 만에 정상상태의 미생물 막이 입려졌는데 그 두께는 64㎛였다. 유동층 반응기에 초기 유입되는 LAS 농도가 120mg/L일 때 LAS 제거율이 93.4%로 최고값을 보였으나, LAS의 대표적인 중간 산물인 sulfophenylalkamoates(SPA)는 초기 LAS 농도에 따라 60-88% 정도의 제거율을 보였다. 최종 유출수중의 SPA 제거율을 높이기 위하여 두 번째 반응기 유입수에 sodium benzoate를 주입한 결과 그렇지 않은 경우 보다 SPA의 잔존량이 40% 감소하였으며 반응기 유출수에 소량의 활성탄을 투입한 결과 유입된 초기 LAS 농도가 350mg/L일 때 LAS는 거의 100% 제거되었고, SPA는 96.2% 제거되었다.
A fluidized-bed bioreactor was used to treat the industrial wastewater containing linear alkylbenzene sulfonate(LAS). Microorganism obtained by acclimation showed low growth rate and substrate inhibition at relatively high substrate concentration. It was found from the experiment using fluidized-bed bioreactor that 64㎛-thick biofilm was made after 15 days. The 93.4% LAS removal efficiency in the reactor was obtained at 120㎎/L of intial LAS concentration. while the removal efficiency of sulfophenylalkanoates(SPA) which is a representative intermediate of biodegradation of LAS was 60-80% depending on the initial concentration of LAS. When sodium benzoate was added to the second reactor, the remaining SPA become lowered by 40% compared to the control experiment. And when activated carbon was added to the reactor, the removal efficiency of SPA was 96.2% and that of LAS was 100% when initial inflowing concentration of LAS was 350㎎/L.
