Abstract

A yeast treatment process was applied to treat food processing organic wastewater containing inhibitory material to anaerobic bacteria. The wastewater contained high concentration of the furfural as a by-product from the food processing. Aerobic yeast (Candida utilis) was selected to remove organics in wastewater. The batch test showed that the wastewater had an inhibition to anaerobic bacteria. The optimum level of temperature for yeast treatment was ranged from 25 to 45$^{\circ}C$. The pH range from 4 to 8 was favorable to yeast growth. The continuous flow reactor was operated at various SRTs. The results were satisfactory with the reduction of COD up to 90％ at SRT of more than 1 day. Through the kinetic study of the yeast, the remained COD concentration was mainly caused by the formation of soluble microbial product (SMP).

혐기성 미생물에 저해가 되는 물질을 포함하는 고농도 폐수의 효모에 의한 처리에 관하여 연구하였다. 폐수는 furfural 부산물이 배출되는 식품가공 공정의 배출폐수를 대상으로 실험하였다. 본 연구에서는 호기성 효모의 일종인 Candida utilis가 실험에 적용되었다. 회분 실험을 통하여 본 폐수는 혐기성 미생물에 저해 영향을 주는 것으로 밝혀졌다. 본 공정의 최적 온도는 25에서 45$^{\circ}C$이었으며 효모의 성장에 적당한 pH는 4에서 8사이임을 알 수 있었다. 연속실험 결과, 체류시간 1일 이상에서 COD가 90% 이상 제거되었다. 그러나 유출수 중의 유기물 농도는 여전히 다소 높은 것으로 조사되었다. 따라서 동력학적으로 해석하여 추정한 결과 남은 유기물은 대부분은 용존 미생물 생성물 (SMP, Soluble Microbial Product)에서 기인하는 것으로 판단되었다.
