Abstract

A company, which is chicken butcherying-plant, was scheduled to increase up to twice output. We researched the way to increase up to twice the processing efficiency at the target biological treatment tank of A company. We performed for this study to obtain the reason why organic matter and nitrogen removal efficiency is increased when MLSS concentration is increased. It's performed at the target of pressure flotation water on SBR system. We performed the research which MLSS was 12,700 mg/L for 30hours (in aerobic condition for 25 hours and in anoxic condition for 5 hours). As a result, the nitrification was happened completely in aerobic condition within 25 hours. Denitrification efficiency was also over 90% when C/N ratio was over 3:1. After the experiment, we changed the concentration of MLSS 5,600 to 12,700 mg/L. In condition MLSS was about 11,000 mg/L and HRT were 30 hours meet the Effluent quality standard.

도계량을 현재의 2배까지 증가시킬 예정인 닭 가공 업체인 A사의 생물학적 처리조를 대상으로 하여 처리효율을 2배까지 높이는 방안을 모색하였다. 이를 위해 MLSS 농도가 증가할 경우 이에 따른 유기물 및 질소 제거 효율증가에 대한 근거를 확보하고자 연구를 진행하였다. 연구는 닭 가공 폐수를 1차 화학 처리한 가압부상처리수를 대상으로 진행되었으며 SBR 형태로 진행되어 호기조 상태 25시간 운전 후, 무산소조 상태 5시간으로 운전되었다. MLSS 12,700mg/L로 진행된 실험 결과 호기조 상태 25시간 이내에 질산화가 완벽하게 일어났으며 C/N비 3 : 1 이상 실험군에서의 탈질효율도 90%를 초과하였다. 후에 진행된MLSS 농도대비 유기물 및 질소제거 효율비교에서는 MLSS 농도를 5,600에서 12,700mg/L까지 변화시켰으며 MLSS 농도 10,800mg/L 실험군에서 유기물과 총 질소 농도 모두 배출허용기준치를 만족하는 결과를 보였다.
