采用重铬酸钾回流法，通过改变冷凝水的温度分别对空白溶液、标准溶液以及工业污水进行测定。最终，由硫酸亚铁铵的消耗量和COD值的变化找出冷凝水温度对COD测定结果的影响。同时对实验结果进行了分析、解释。
採用重鉻痠鉀迴流法，通過改變冷凝水的溫度分彆對空白溶液、標準溶液以及工業汙水進行測定。最終，由硫痠亞鐵銨的消耗量和COD值的變化找齣冷凝水溫度對COD測定結果的影響。同時對實驗結果進行瞭分析、解釋。

The blank solution,standard solution and industrial wastewater were determined respectively by the method of potassium dichromate reflux through changing temperature of the condensed water. In the end, the influence of condensed water temperature on determining COD was found out through analyzing consumption of ammonium ferrous sulfate and the change of COD value. At the same time, the experimental results were analyzed and explained.
