초록

제약폐수처리장과 판지폐수처리장의 활성슬러지 또는 폭기 조 media로부터 분리한 균들과 type culture들을 첨가할 경우 제약폐수와 판지폐수의 처리에 도움을 주는지를 알아보았다 폐수에 균틀을 배양하였을 때, 제약폐수에서는 charcoal m media로부터 분리한 Bacillus종 (PC-3)이 특이하게 잘 증식하 여 24시간 배양후의 생균수가 $1.1{\times}10^6m/L$를 나타내었으며, 판지폐수의 경우에는 type cultute인 Bacillus subtilis KCTC 1028이 가장 잘 증식하여 24시간 배양후의 생균수가 $1.1{\times}10^7m/L$를 나타내었다. PC-3률 첨가하는 제약폐수의 회분식처 리실험에서 균첨가효과가 확인되었으며8일째의 첨가구의 C COD제거율이 무첨가구의 COD제거율에 비해 18% 더 높았다. Bacillus subtilis KCTC 1028 을 첨가하는 판지폐수의 회 분식처리실험에서도 균첨가효과가 확인되었으며, 24시간후의 첨가구의 COD제거율이 무첨가구의 COD제거율에 비해 14% 더 높았다. Bacillus subtilis KCTC 1028은 전분질원료 주정 폐 액에서 잘 증식하였으므로, 전분질원료 주정폐액을 Bacill따 s subtilis KCTC 1028의 경제적인 생산배지로 이용할 수 있다.

Some bacterial strains isolated from activated sludges and media and type cultures were cultivated in a pharmaceutical wastewater and a paperboard wastewater and added during batch treatment of those wastewaters in order for these strains to increase the treatment efficiency. Bacillus sp(PC-3) isolated from the charcoal media of the pharmaceutical wastewater plant grew remarkably over there strains in that wastewater and the viable cell count after 24hr cultivation was $1.1{\times}10^6m/L$. Bacillus subtills KCTC 1028 a type strain grew best in the paperboard wastewater and the viable cell count after 24hr cultivation was $1.1{\times}10^7m/L$. Addition of PC-3 in a batch treatment of the pharmaceutical wastewater increased COD removal by 18% after 8 day. And addition of Bacillus subtills KCTC 1028 in a batch treatment of the paperboard wastewater increased COD removal by 14% only after 24hy Bacillus subtills DCTC 1028 was though to be able to be produced economically using alcohol distillery wastewaters from starch material.
