【Abstract】 The COD of rifampin in wastewater is 6×10\+4mg/L or higher. After treated with PFS and C\|PAM flocculants, the COD is reduced by 27%. BOD\-5/COD\-\{Cr\} increases from 0.19 to 0.32. According to the chromatographic analysis and the water quality comparison before and after treatment, five organic substances are removed by 22% each. That makes the possibility of biochemical treatment. After diluted in biochemical pool and nine days activated sludge process, the COD has been reduced from \{1.5×10\+4mg/L\} to less than 300mg/L. This result meets the purpose of the project.更多还原
