| 中文摘要 |
| 本文研究苯酚在细砂土层中的迁移转化规律,包括静态吸附、降解及动态土柱实验三部分.实验结果用计算机进行线性拟合和参数估值.研究结果表明:细砂土对苯酚的吸附能力较差而降解能力较强;在好氧条件下,苯酚更易降解;水中存在的其它有机物在一定时间内会影响苯酚的降解,但随着微生物对苯酚逐渐适应,这种影响可被消除。 |
| 英文摘要 |
| The transport and transformation of phenol in saturated fine-sand soil were studied. The study included static adsorption, static degradation and dynamic soil column experiments. Longitudinal dispersion coefficient (D), adsorption coefficiet (K1) and biodegradation coefficient (K1) were obtained through curve fitting and parameter estimation. The results indicate that phenol is hard to be adsorbed by the fine-sand but readily biodegraded in the soil.Aerobic condition can fasten the degradation process. The existence of other organic compounds retarded the degradation, but this effect disappeared once the microorganisms became adapted to phenol. |
