| 摘 要： | 介绍了共代谢的类型、特点和影响因素。共代谢过程针对各种生物难降解物质需选择各自合适的一级基质，而且一级基质与难降解物质需保持合适的浓度比；共代谢过程中微生物不仅需要足够的C、N、P等营养元素，而且微量营养元素的加入也是必须的。考虑各方面因素并有效地控制才能使难降解物质达到较高的共代谢率。

| Abstract: | Cometabolism is an efficient way for biodegradation of refractory organic compounds.The mechanism,characteristics and affecting factors of cometabolism are presented.The proper primary substrate of cometabolism must be selected according to different refractory compounds.Moreover it should keep a proper ratio of primary substrate concentration to refractory compound concentration.The microorganism needs not only sufficient C,N,P nutrients,but also microelements in cometabolism.Taking into consideration and efficiently controlling the concerned factors are essential to reach higher efficiency of cometabolism. |

| Keywords: | refractory organic compounds biological degradation cometabolism wastewater treatment |
