      본 연구는 생물학적 영양염류제거에 있어 돈사폐수의 반응특성을 고찰하기 위하여 수행되었다.반응특성으로는 돈사폐수 욘존 COD의 약 66.1%는 생물학적 분해가 빨리 일어나는 유기물이였으며, 생물학적 분해가 불가능한 용존COD는 약 11~12%였다. 호기성 고정생물막 반응조에서 질소는 탈기 ,질산화, autotrophic,과 heterotrophic미생물의 세포합성으로 제거되었는데, 제거율은 각각 12.1%,68,9%15,0% 그리고 4.0%였다. 돈사폐수

      This study was performed to investigate the reaction characteristics of piggery wastewater for biological nutrient removal. The reaction characteristics discussed the fraction of organics the behavior of nitrogen, nitrification, denitrification and the behavior of phosohorus. The fraction of readily soluble COD was 11~12 percent. The ammonia nitrogen was removed via stripping nitrification autotrophic cell synthsis and heterotrophic cell synthesis. The removal percents by each step were 12.1%, 68.9%, 15.0% and 4.0% respectively. Nitrification inhibition of piggery wastewater was found to occur at an in fluent volumetric loading rate over 0.2 NH_(3)-Nkg/㎥/d. Denitrification rates were the highest in the raw wastewater and the lowest in the anaerobic effluent. The denitritation of piggery wastewater came out to be possibe, and the rate of organic carbon consumption deceased about 10 percent The phosphorus removed was released in the form ortho-p in the aerobic fixed biofilm reactor it was caused by autooxidation. The synthesis and release of phosphorus were related to the ORP and the boundary value for the phase change was about 170mV. In the synthesis phase, the phosphorus removal rate per COD removed was 0.023mgP_(ayn)/mgCOD_(rem) The phosphorus contents of the microorganism were 4.3~6.0% on a dry weight basis
