본 연구는 활성슬러지 공정에서 clinoptilolite의 첨가가 질산화에 미치는 영향을 파악하기 위해 수행되었다. 실험결과, 주입된 clinoptilolite는 시스템내 미생물 농도를 10,800 mg·MLVSS/l까지 상승시켰다. 또한 peptone inhibition에 대해 표준 활성슬러지 공정과 달리 90% 이상의 질산화율을 나타냈고, 0.42kg·TKN/m(3)·d의 질소 부하변동에도 빠른 순응을 보이며 전체 시스템에 안정한 질산화율이 유지되었다.
This study was performed to evaluate the effect of clinoptilolite addition on nitrification in activated sludge process. As a result, clinoptilolite dosage increased microbial concentration by 10,800 mg ·MLVSS/l. In addition, the application of clinoptilolite improved nitrification by 90% approximately, despite of peptone inhibition and revealed stable nitrification at 0.42 kg·TKN/m(3)·d.
