        Gaowa,Yasuzo Sakai,Xiaonan Xie,Mihir Lal Saha,Ikko Ihara 한국초전도저온공학회 2021 초전도와 저온공학 Vol.23 No.3

        Milking parlor wastewater contains not only high concentrations of organic compounds, but often animal antibiotics. To discharge the antibiotics to public water area cause problem of antibiotics resistant bacteria. Magnetic separation was applied into improvement of milking parlor wastewater treatment process. A new process, composed of a magnetic activated sludge (MAS) process and a contact oxidation (CO) process, was proposed in this study. This process was evaluated by the simulated milking parlor wastewater (4500 mg/L CODCr and 10 mg/L tetracycline) using a bench scale experimental setup. As a result, the process was able to removed 97% CODCr as well as 94% tetracycline. The MLVSS (mixed liquor volatile suspended solids) concentration of MAS was maintained at 12000 mg/L without excess sludge drawing. This process was considered to be useful as treatment process for milking parlor wastewater in which waste-milk including antibiotics is often discharged.
