| 摘 要： | 采用间歇式活性污泥反应器（SBR）降解含正丁醇的自配水实验过程中，发现即使正丁醇属可被完全生物降解有机物，并且在启动时系统中不含可溶性生物不可降解物质，在其降解过程基本结束时系统的溶解性COD值也只能达到一最低点，并非趋向于零，而且此后COD值还会继续呈稳定的增长趋势。实验结果还显示，该最低点的COD值及可溶性微生物产物（SMP）的产生速度与温度有关。

| Abstract: | The biodegradation processes of artificial waste-water containing n-butyl alcohol in SBR indicated that the soluble COD value of the system could only get to minimum and not zero, even the system did not contain any unbiodegradable organics. The soluble COD value of the system would keep an increasing trend if the system was operated continuously. It also found that the minimum and the increasing rate of COD were related to the temperature. |
