| The purpose of this study was to remove an phosphorus ion using iron electrolysis device in a sequential batch reactor(SBR) and to analyze the effect phosphorus efficieny. Iron electrolysis device was applied to SBR process plant which is appropriate to the processing facilities of small scale and which is excellent in disposal capacity about flux change of 60㎥/day flowed real sewage. It was designed in a fashion that the output voltage of iron electrolysis device was 12V, current density was 3mA/cm2, interval of iron plate module was 1.3cm, size of iron plate module 40cm×40cm, and number of iron plate module was 6set. It was operated in the aerobic process. When the iron was used, the nitrogen remove efficieny increased from 71.6% to 75.2% and phosphorus increased from 81.5% to 91.4% respectively. Especially, BOD, CODMn, SS, T-N, and T-P of process efficiency increased about 2.2%, 6.1%, 2.0%, 18.3%, and 24.8% respectively when iron electrolysis device was used. This result concluded that iron electrolysis device compensates the decline of biographical process efficiency because of the decline of microorganism activity. |
