摘要
本文对南四湖港口污染物扩散区内的ＣＯＤ降解规律进行了室内模拟试验研究，采用最小二乘法估计出了ＣＯＤ可降解部分的降解系数和不可降解部分的百分比，并通过方差分析验证了模型的可靠性。ＣＯＤ降解系数和不可降解百分比的获取，可以为预测各港口对南四湖水质变化趋势的影响，为制定相应的水污染防治规划和措施，提供了重要的基础数据。
The COD degradative law in the port pollution regions of Nansi Lake was studied by the indoor simulating test,and the degradation coefficients of decomposable COD and the percentage of undecomposable COD were estimated by the least square method.The model reliability was demonstrated by variance analysis.The estimated COD degradation coefficients can provide the pridiction of water quality variation tendency in the ports of Nansi Lake and the establishment of water pollution protection and control plan with important basic data.
