초록

Poly acrylamide(PAA)와 활성슬러지를 포괄법 에 의하여 고정화 담체를 제조하였다. 이 고정 화 담체를 이용하여 폐수처리에서의 적용 가능성과 특성을 조사하였다. 본 연구에서는 실제 폐수처리 공정에 적합한 12% acrylamide농도의 담체를 구하였다. 그리고 sequencing batch reactor(SBR)에서 30일 동안 운전한 결과, TOC와 인의 제거효율이 각각 95%와 70%를 나타내었다. 또한 이 연구 결과로부터 반복적인 혐기와 호기 조건의 사이클 운전이 TOC와 인의 제거효율을 향상시킴을 알 수 있었으며, 운전기간 중에 PAA고정화 담체는 깨짐이 없이 사용되었다.

This study was conducted to evaluate the feasibility and characteristics of poly acrylamide (PAA) immobilized sludge as a microbial entrapment bead for wastewater treatment. In the PAA method of immobilized sludge, it was found that the optimum acrylamide concentration for actual wastewater treatment was to be 12%. When the sequencing batch reactor (SBR) was operated during 30 days, removal efficiencies of TOC and phosphate was 95% and 70ft, respectively. From this research, repeated cycle of anaerobic and aerobic conditions is required to enhance the removal of TOC and phosphate. During the operation, immobilized cells could be used without being disrupted.
