分散染料的生物降解性能

采用了[BOD5]／[CODcr]和呼吸速率曲线两种方法对6大类14种分散染料的好氧生物降解性能进行测试。实验表明，分散染料在好氧状态下大都难降解。然后又考察了这些染料的厌氧生物降解性能，发现这些染料经厌氧反应后大都变得可生化降解，并且染料结构与其降解性能之间有一定的关系。

The Biodegradability of the Disperse Dyes

The aerobic degradation of the 14 disperse dyes in 6 types was tested by the way of BOD5/COD and microbiological respiratory rate test. The results show that the biodegradability of most of the disperse dyes is poor. And then the anaerobic degradation of the 14 dyes was studied, which show that the biodegradability of most of them is improved after the anaerobic reaction,and there is some relation between the structure and the biodegradability of the disperse dyes.
