Abstract
In this study, effects of substrates and nitrate on biological phosphorus release in EBPR(enhanced biological phosphorus removal) process were examined using batch test apparatus at anaerobic conditions. The sludge used in this experiments was taken from SBR(sequencing batch reactor) treating swine wastewater at aeration period. Phosphorus release rates obtained with substrates of FSW(fermented swine wastewater), acetate, propionate, domestic wastewater and methanol were 6.19, 5.99, 1.52, 1.2 and
본 연구에서는 EBPR(enhanced biological phosphorus removal)공정에서 인 방출에 대한 유기물 및 질산염의 영향을 혐기성 조건에서 회분식 실험으로 관찰하였다. 본 실험에서 사용한 슬러지는 축산폐수를 처리하기 위한 SBR(sequencing batch reactor) 공정의 호기성 상태에서 채취하였다. 유기물인 FSW(fermented swine wastewater), acetate, propionate, 도시하수 및 methanol의 인 방출 속도는 각각 6.19, 5.99, 1.52, 1.2 및
