该文研究了不同金霉素浓度下畜禽养殖废水厌氧生物处理系统的COD去除率和产甲烷量，运用PCR DGGE及差异DNA片段回收克隆测序的方法分析了金霉素对该厌氧生物处理系统细菌多样性的影响。结果表明随着金霉素浓度的增加，畜禽养殖废水的COD去除率和产甲烷量均会受到抑制，产甲烷量差值从6．9％扩大到29．2％，COD去除率从90．89％降至86．96％，而对照组COD去除率达到94．46％。PCR DGGE分析表明金霉素胁迫能够显著降低畜禽养殖废水厌氧生物处理系统中的细菌多样性，细菌群落丰富度值从0．913降至0．652，而对照组的丰富度值为1。

COD removal rate and methane yield of livestock wastewater at different concentration of chlortetracycline were studied. The influence of bacterial diversity was analyzed by PCR DGGE,cloning and sequencing. The results indicate that with the increase of chlortetracycline concentration,the removal rate of COD and methane yield are both restricted. Difference values of methane yield expand from 6. 9% to 29. 2% and COD removal rate falls to 86. 96% from 90. 89%,while that of the control group is 94. 46%. Results of PCR DGGE indicate that with the increase of chlortetracycline concentration,bacterial community richness values fall to 0. 652 from 0. 913,while that of the control group is 1,which means that chlortetracycline decreases the bacterial diversity of livestock wastewater.
