Abstract
A wastewater purifying system using phototrophic bacterium, Rhodopseudomonas capsulata, is currently in operation in several countries, One of them, is a continuously aerated bioreactor(CABR) system, which treats concentrated swin wasterwater using small amounts of phototrophic bacteria as additive bacterial seeding. Using this plant, total biochemical oxygen demand was decreased to 13%, and most of volatile fatty acids were removed. About 40% of the wastewater(Influx) was evaporated during aerobic digestion for 24h, and 60% of that erupted in a decodorized foam(Efflux). The efflux had enough nutrients, N, P and K kor growing plant, as well as organic matters. When the efflux was applied to Italian ryegrass with high dose, fresh shoot and root weights were significantly greater, and
본 연구는 최근 개발된 광합성세균(Rhodopseudomonas capsulata)을 이용한 연속적 폭기식 생물 반응조(이하 CABR)를 이용한 무희석 양돈 분뇨의 처리 결과를 보고하고 있다. CABR를 이용하여 24시간 동안 양돈 분뇨를 폭기 처리한 결과 유입량의 40%가 증발되었고, 유입분뇨의 전체 BOD, COD중 87%, 32%가 각각 제거되었으며, 전질소(T-N), 전인(T-P)은 각각 110%, 112%로 증가되었다. CABR 배출액의 질소 형태를 분석한 결과 암모니아성 질소(
