Nitrification and Removal of Pathogenic Microorganisms Indicators by an upgraded RBC

생물막공정을 이용한 질산화 및 병원성 미생물의 제거

Experiments on an upgraded RBC were conducted to investigate its removal efficiencies of $NH_4-N$, coliform group and coliphage in the municipal wastewater treatment. A bench scale RBC, made of stainless mesh media with 5mm high surface protrusions, was fed with settled municipal wastewater containing 13-25mg/l of $NH_4-N$ and 40-75mg/l of TOC at the hydraulic loading of $89l/m^2.d$ and $60l/m^2.d$. It was found that the nitrification effectively occured at bulk liquid TOC concentration of less 10mg/l. The coliform group and coliphage were more than 98% and 90%, respectively.
