| 摘 要： | 厌氧消化技术被广泛用于猪场废水的处理,为探明四环素类抗生素对猪场废水对厌氧消化产生抑制作用的边界浓度值,选用了2种常用的四环素类抗生素土霉素和金霉素作为抑制剂,用重铬酸钾法测出COD,以COD去除率反映抗生素的独立抑制和联合抑制效果,结果显示:土霉素、金霉素对厌氧消化的最低抑制浓度分别是0.3、0.1 mg/L,且2种抗生素的联合抑制效果大于单独抑制效果。

| Abstract: | Anaerobic digestion technology is widely used in the treatment of piggery wastewater.In order to investigate the boundary concentration of inhibitory effect of tetracycline antibiotics against anaerobic digestion,Oxytetracycline and Chlortetracycline were chosen as the inhibitors.Potassium dichromate method was used to measure COD values,and COD removal efficiency was used to reflect the single inhibition and combined inhibition of these two antibiotics.The results showed that the lowest inhibition concentrations of Oxytetracycline and Chlortetracycline against anaerobic digestion were 0.3 mg/L and 0.1 mg/L respectively,and their combined inhibiting effect was stronger than the single inhibiting effect. |
