호기성 그래뉼 슬러지가 생물흡착제로 적절한 이유는 무엇인가? | 한편, 미생물의 자가 고정화(self-aggregation) 현상에 의해 형성되는 호기성 그래뉼 슬러지는 활성슬러지 대비 고밀도이며 우수한 침전성을 보유하고 있어 이온성 물질의 흡착처리 후, 고액분리가 용이한 장점이 있다(Wang et al., 2018). | |
칼슘의 특징은 무엇인가? | 칼슘은 인체에 가장 풍부한 주요 미네랄 성분 중 하나인 양이온 물질로써(Zhu et al., 2018), 신체 내 99%는 뼈의 강도와 강성을 담당하며 1%는 세포 기능을 담당하는 것으로 알려져 있지만(Bae and Kratzsch, 2018), RO(Reverse Osmosis) 농축수, 산세폐수 등과 같은 생물학적 처리공정의 유입 폐수에 존재할 경우, 미생물의 기질 흡착을 방해하고 질소성분의 질산화 및 탈질 반응을 지연시키는 것으로 보고되고 있다(Choi, 2014; Kim, 2015; Park and Lee, 2015). 중금속 물질을 포함한 이온성 물질의 처리에는 화학 침전(Chen et al. | |
생물흡착을 이용한 이온성 물질 처리 방법의 장점은 무엇인가? | , 2018) 방법을 이용한 공정이 적용되어 왔다. 이러한 공정 중 생물흡착을 이용한 기술은 낮은 운영비용, 고효율 및 비교적 적은 슬러지 생산 등의 장점이 있어, 조류(Davis et al., 2003), 균류(Binupriya et al. |
