| 中文摘要 |
| 以松花江不同地点的江水和沉积物为微生物源,对江中检出的21种有机污染物混合体系的生物降解过程进行模拟研究。结果表明,化合物结构、微生物源和驯化期是影响生物降解的主要因素;在驯化条件下,低浓度混合有机污染物的生物降解速率符合一级动力学方程。 |
| 英文摘要 |
| A study was made to simulate the biodegradation Ptocess of a mixed system of 21 orgnic pollutants which were detectable in the songhuajisng myer, by using the water samples and sediments collected from different sites of the River as the sources of microorgsnism. The results showed that the main factors affecting the biodegradation included the structures of comPOunds, the sources of microorganism, and the Period of acclimation. Under the conditions of acclimation, the rate of the biodegradation of mixed orgsnic pollutants at a low concentration was found to fit the equation of first order reaction kinetics. |
