유용미생물 발효물의 Struvite 형성과 질소, 인 제거 효과 = EM(Effective Microorganisms) Activated Liquor Effect on Struvite Formation for Nirogen, Phosphorus Removal

다국어 초록 (Multilingual Abstract)

Sruvite crystallization is good for high removal efficiency of nitrogen and phostphate in wastewater. In this study, several experiments were carried out with two kind of artificial wastewater which were added EM(Effective Micoorganisms) activated liquor or not, to find out the characteristics of each Struvite crystal formation and their affection on nitrogen and phosphous removal. From the results, though the EM activated liquor was rolled to consuming the alkalinity needed to crystal formation, the amount of alkalinity, demanded to reach pH 9, was enough to optimal EM crystal formation condition. At the time, the removal mol ratio of Mg²⁺, NH₄⁺-N, PO₄^3--P was estimated about 1.0:1.3:1.6. Therefore, it could be assumed that the by-products like a organic acid on EM activated liquor support to make a micro crystal formation and a formation of muti-cluster with nitrogen and phosphate.
