영양소 주입에 의한 당면폐수처리의 성능평가 = Performance Evaluation of Noodles Wastewater Treatment by Feeding Nutrient

다국어 초록 (Multilingual Abstract)

This study was performed to evauate for the noodles wastewater with high viscosity and low nutrient (Nitrogen, and Phosphorus). To add nutrient to grow activated sludge highly, about. 2 kg/day fertilizer that contains nitrogen was fed to the influent. Both the status of the aeration tank and the treatment performance were observed. Before feeding nutrient, the MLSS concentration in aeration tank was about 1,400 ㎎/L, and Spharotilous, Thiothrix. Prordon etc. were detected, while the BOD, COD and SS removal efficiency were so low as 78%, 77% and 56%, respectively. After feeding nutrient the MLSS concentration in aeration tank was increased to about 2,700 ㎎/L, and Epistylis. Monostyla, Voticella etc. were observed to be prolific. Meanwhile average 98% of BOD, 94% of COD, 71% of SS were removed, the microorganism can be activated to improve the noodles wastewater treatment performance. It is recommend to set up thickener and dewatering facilities to treat wasted activated sludge.
