표면개질 담체를 이용한 충전탑 반응기에서 유기물 제거 및 미생물 부착 특성

다국어 초록 (Multilingual Abstract)

This study was accomplished using packed bed column reactors that contain nonsurface-modified polypropylene media and surface-modified media from hydrophobic surface property into hydrophilic property by ion beam irradiation. The objectives of this research was investigated the characteristics of organic compounds removal and microbe attachment from sewage of school cafeteria in these reactors. In 736.8 mg/L of the average inflow CODCr concentration the reactors with and without surface modification showed
81.8% and 70.3% of average CODCr removal efficiencies, respectively, which proves the CODCr removal efficiency of surface-modified media reactor is higher than that of nonsurface-modified media reactor. After 90 days, there were maximum differences between modified system and nonmodified system. In that time the maximum removal efficiency of CODCr was 96.5% in modified system and was 85.2% in non-modified system that showed removal efficiency of surface-modified media system is 11.3% higher than that of nonsurface-modified media system. The average removal efficiency of SS was 80.4% for the surface modified system and 61.6% for the non-modified system under same condition. Also, the reactor of surface-modified media has advantage on microbe attachment and biofilm formation.
