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.
