| 摘 要： | 对汾江河本底LAS(直链烷基苯磺酸盐)静态降解情况进行了实验测定，讨论了LAS生物降解影响因素计算确定了河水LAS降解系数。研究测定结果表明，前12h的降解速率与LAS的初始浓度关系十分密切，LAS的初始浓度越低，前12h的降解速率越高。天然水中微生物对高浓度LAS的降解动力有所削弱。

| Abstract: | The static degradation of LAS in fenjian River is experimentally determined.According to the experimental data,we discuss the main factors which influence the biological degradating rate of LAS, and calculate the degradation coefficient of LAS.It is stated that the degradation of LAS at former 12 h relates closely to its initial concentration,The initial concentration of LAS is lower, its degradating rate at former 12 h is higher.The microbe can be restrained to degrade LAS in natural water when its LAS concentration is higher. |
