Xeronine as bio-stimulant was injected in the anaerobic sludge and the activated sludge treating wastewater in order to examine the effect of hidden benefits. Bio-stimulant did not show significant improvement of anaerobic treatablity. In the aerobic system, higher bio-stimulant dose condition resulted in slightly more removal of nitrogen and phosphorus. Floc aggregation and zone settling velocity as solid-liquid separation factors in activated sludge systems was enhanced by bio-stimulant. Effects of bio-stimulants injection on improvement of water quality and microbial activity did not clear in terms of normal operation conditions. 한국물환경학회 생물학적 하·폐수 처리 공정에서 생물촉진제 첨가의 영향 Effects of Bio-stimulant Addition on Biological Wastewater Treatment Processes Article 2 한국물환경학회지, v.21, no.4, pp.398 - 402 한국물환경학회지 21 4 398 402 kci ART000968797 Biological treatment Bio-stimulant Methane production Microbial activity Settleability Biological treatment Bio-stimulant Methane production Microbial activity Settleability
