摘　　要：对升流式厌氧污泥床(UASB)、厌氧复合床(UBF)、内循环厌氧反应器(IC)3种厌氧工艺处理金霉素废水进行了比较研究.研究了反应器的结构特点,从反应器内污泥浓度和传质过程、工程投资等方面分析了3种厌氧工艺对金霉素废水的处理效果.结果表明:IC反应器在容积负荷(Nv)为5.5 kg/(m3.d)(以CODCr计)时,CODCr去除率平均值为84.36%;UBF反应器在容积负荷为3.5 kg/(m3.d)时,CODCr去除率平均值为75.04%;UASB反应器在容积负荷为3.0 kg/(m3.d)时,CODCr去除率平均值为71.43%.IC反应器与UASB和UBF反应器相比,在容积负荷,CODCr去除率和工程投资方面都具有明显的优势,是处理金霉素废水可取的厌氧工艺.Three anaerobic technologies （UASB, UBF, IC） in chlortetracycline wastewater treatment were compared. The structure characteristics of the reactors were studied, and their removal efficiency analyzed from aspects of the concentration of sludge, the process of mass transfer and the investment, The results indicated that when the volume load of IC reactor was 5.5 kg/（ m^3 · d） （ estimated by CODcr ）, its averaged removal rate of CODcr was 84.36% ; for UBF reactor, when the volume load was 3.5 kg/（m^3 ·d）, its removal rate of CODcr was 75.04% ; and for UASB reactor, when the volume load was 3.0 kg/（m^3 · d）, its removal rate of CODcr was 71.43 % . It was conclude that compared with the other two anaerobic reactors, IC reactor has obvious advantages in volume load rate, removal rate of CODcr and investment, and should be the best available anaerobic technology in chlortetracycline wastewater treatment.
