摘要
活性污泥模型自推出以来就在欧美得到了广泛应用.为实现对活性污泥处理过程的准确模拟,需要提供包括COD组分在内的详细的水质特性参数.传统的COD指标因不能区分废水中的含碳有机物而需要进行进一步划分.为此,介绍了活性污泥模型对进水COD组分的划分,分析了这些组分的物理化学和生物学特性,回顾了每个COD组分的测定方法,评价了这些测定方法的优缺点,讨论了进水COD组分测试中存在的问题,并提出了测定方法的规范化、标准化思想.
The Activated Sludge Models were widely applied in Europe and America since they were put forward, however, for an accurate simulation of the activated sludge treatment processes, reliable wastewater characteristic parameters such as COD components were needed. The conventional parameters such as COD can not differentiate the carbonaceous organic matters of wastewater, so they need to be divided again. Therefore, the fractionation of influent COD components in the Activated Sludge Models is introduced, and the physical-chemical and biological characteristics of each COD components are analyzed. The measurements of influent COD components are reviewed and some evaluation is made. The issue in determining the influent COD components is discussed. The idea of establishing a characterization guideline is put forward at last.
