Abstract: The application of biological contact oxidation as the core of the biochemical treatment process to cepha-losporin wastewater treatment projects has been investigated. According to the specific conditions of the wastewater on site,the single factor analysis method has been used for the determination of the following operation parameters in the system:time for film formation is 20 days,the best pH 7.0-8.0,the best DO 3.0 mg/L or so,the best HRT of the first contact oxidation pool 24 h,and that of the second contact oxidation pool 15 h. The total removing rate of ammonia nitrogen and COD_Cr from high concentration organic wastewater reaches 90%,which has practical reference and app-lication value.

Key words: cephalosporin wastewater, wastewater treatment, biological contact oxidation

摘要： 研究了生物接触氧化作为生化处理主导工艺在头孢菌素废水处理工程中的应用，结合现场废水具体条件，采用单因素分析法确定系统中生物接触氧化池的挂膜天数为20 d，最佳pH为7.0~8.0，最佳溶解氧为3.0 mg/L左右，接触氧化一池最佳水力停留时间为24 h、接触氧化二池为15 h。该工艺对高浓度有机废水中氨氮和COD_Cr的总去除率达90%左右，具有实际参考应用价值。
