| 摘 要： | 潮汐河网具有其独特的水物理及水化学特性。本文采用珠江三角洲河网区域20个水样的BOD降解实验数据,并用BOD反应一级动力学方程进行数据拟合,结果表明,潮汐河网水体BOD降解过程的延滞期消失,远离污染源河段河水的BOD降解过程两阶段区分不明显,降解过程符合BOD反应一级动力学方程。此外,潮汐河网河水的降解系数随时间的变化过程是随机的

| Abstract: | There are some special physical and chemical characteristics in tidal river networks. The study presented includes not only the analysis of the laboratory BOD degradation statistics of observed samples in the waterways of Pearl River Delta, but also the application of the first-order BOD kinetics equation fitting to the observed data. It appears that lag period of the BOD degradation process in the waterways of tidal rivers disappears. The differences between the two phases of the degradation process in water-bodies are not clear which far away from pollution sources, and the degradation process follows the first-order BOD kinetics equation well. In addition, the process of the degradation coefficient changing with time in the waterways of tidal river networks is random. |
