| 中文摘要 |
| 从处理焦化废水的活性污泥中,通过富集驯化培养,平板划线纯化,分离出了5株能有效降解邻苯二甲酸二丁酯(DBP)的菌株。利用摇瓶实验,对各菌株的降解能力进行了比较,研究了菌株的生长特性和降解过程动力学。结果表明,邻苯二甲酸二丁酯的生物降解过程可用Moned方程描述,其动力学参数μm和Ks分别为0.4h-1和28mg/L。 |
| 英文摘要 |
| Microorganisms capable of degrading di-n-butyl phthalate (DBP) were isolated from coke-plant wastewater treatment plant sludge by enrichment and acclimation shaking culture,and purified by successive streak transfer on agar-plate medium.The time course of DBP degradation by different strains was investigated and compared. The growth characteristics and the kinetics of DBP biodegradation were studied by shaking flask test. The experimental results show that the DBP degradation can be described by Monod equation with pm and Ks being 0.4h-l and 28mg/L,respectively. |
