白酒工业废水化学需氧量的测定重铬酸盐法不确定度因素的探讨

Determination of Chemical Oxygen Demand in Liquor Industrial Wastewater by Dichromate Method

通过重铬酸盐法测定白酒工业废水化学需氧量的分析,建立化学需氧量合成标准不确定度的数学模型,分析不确定度的来源。应用一个对白酒工业废水测定的实例,对不确定度分量进行了详细的评定,分析得出对化学需氧量标准不确定度影响大小。

Through the dichromate method to determine the chemical oxygen demand in the industrial waste water, establish the mathematical model of the standard uncertainty of chemical oxygen demand, and analyze the source of uncertainty. An example of the determination of the industrial waste water in liquor-making industry was used to evaluate the uncertainty components in detail, and the influence of the standard uncertainty on the chemical oxygen demand was analyzed.
