Abstract
플라스틱 담체(PVC) 표면을 화학적으로 전처리하여 활성오니의 부착을 촉진시키고자 하였다. 고정화된 미생물량을 근거로 여러 전처리 방법들의 효율을 비교한 기초 실험에서는 chlorosulfonic acid에 의한 chemical etching과 PEI(polyethylenimine)처리를 병행하는 것이 다른 방법에 비해 2-5배의 부착 촉진 효과를 보였다. 이때 측정된 부착량은 2.5g/m2이며, 전처리를 하지 않은 담체에서는 부착이 거의 일어나지 않았다. 전처리된 담체를 이용하여 PEI의 농도, 부유 미생물의 농도(MLSS), 기질의 농도 등이 활성오니의 부착에 미치는 영향을 고찰하였다. 결정된 각 인자들의 최적치를 연속 반응기에 응용하여 미생물의 부착실험을 수행한 결과 정상상태의 생물막 형성기간을 기존의 공정에 비해 2-3배 단축할 수 있었다.
This study was performed to improve the biofilm formation on the plastic support(PVC) through chemical modification of its surface. The method using chlorosulfonic acid and PEI(polyethylenimine) showed 2-5 times higher attached biomass than the results obtained with other treatments. In the test, the amount of attached dry cell weight was 2.5g/m2, while that from the untreated support was negligible. Effects of several factors such as PEI concentration, suspended cell mass, substrate concentration on the biofilm formation were investigated. It was confirmed that the time required for the biofilm formation on the new plastic support could be shortened 2-3 times compared to that of conventional systems.
