在流体污染控制中,污染物的分析是个关键因素。除非对污染度进行监测,否则控制的程度是不得而知的。分析方法取决于所评定的是哪一种污染物及要求掌握污染物的哪些情况。一般来说,要求找出污染物并加从辨别,然后找出它们的特征,最后以明白易懂的方式进行描述并写在报告上。具体地说,污染物分析必须致力于下列描述污染物的因素: In the fluid pollution control, the analysis of pollutants is a key factor. Unless the degree of pollution is monitored, the degree of control is unknown. The method of analysis depends on which of the contaminants are assessed and what conditions are required to master the contaminants. In general, it is required to identify the contaminants and identify them, then to find out their characteristics, and then to describe them in an understandable way and write them on the report. Specifically, the analysis of contaminants must address the following elements that describe the contaminants:
