| 中文摘要 |
| 根据合成染料的特性选用了较简单易行的3种生物降解性能测定方法,即静置烧瓶筛选试验法,瓦勃氏呼吸仪法,半连续活性污泥法试验,对26种染料进行了测定分析,并比较了3种方法的结果和原因。同时,就环境因素对有机物生物降解性能测定的影响作了简要讨论。结果表明,多数染料在好氧条件下是难降解的,半连续活性污泥法试验虽然需较长的时间,但较另2种方法准确。 |
| 英文摘要 |
| hree simple and practical aerobic biodegradability test methods, i. e., static flask screening test,Warburg respirometry and semi--continuous activated sludge system, were chosen depending on the characteristics of dyes to test the biedegrndabilities of 26 water soluble dyes. The resultS of testS using these three methods were compared and the reasons for the differences between these resultS were explained. The effects of environmental fsctors on the biodegradability tests were also discussed. It was found that most of the dyes studied are refractory under the aerobic conditions, and the semicontinuous activated sludge system is a favourable and more precise test method although it takes a longer time. |
