| Abstract |
| This study was performed to improve nitrification using Nitrification tank that was applied RBC in M-Dephanox. The existing M-Dephanox process was using fluent media likes EPS media, Linphor media to grow nitric acid bacteria in Nitrification tank. But such fluent media brings deterioration of nitrification efficiency forming Dead zone, when activated sludge adsorbed organic matter is flowing into Nitrification tank. To solve this problem, we apply RBC to Nitrification tank and extract activated sludge by friction resulting from the rotation. So we carry out smooth nitrification. The result of an experiment, removal efficiency of TCOD More than 93% was showed in influent TCOD loading rate 1.0~2.5 kg/m3·day range. In addition, NH4+-N removal efficiency of Nitrification tank, according to the organic load introduced in Nitrification tank was showed approximately 89% of the NH4+-N removal efficiency when the load range of organic matter even increased to 0.04~0.14 kg/m3·day. The case of phosphorus, T-P , PO43--P was the more influent loading rate is rising, the more removal efficiency is rising. Therefore, the RBC applied process in Existing M-Dephanox process is not only bring a High nitrification efficiency but also perform the stabler nitrification efficiency then inflowing organic matter. |
