浅析水体化学需氧量的检测方法

Analysis of the Detection Method of Chemical Oxygen Demand (Cod) Water

要检验水质的好坏有几个指标,其中最重要的受污染指标就是水体的化学需氧量,这个指标的结果是所有指标中权重最大的。目前来说检测水质化学需氧量的方法比较多,其中氧化法是最常见的,但这种方法也存在一定的弊端,以下对水质检测的指标做出了一定的分析供大家在检测水质的时候作为参考标准。

To test the quality of water there are several indicators, the most important indicator of pollution is the chemical oxygen demand （cod） of the water body, the result of this indicator is the largest weight of all indicators. At present, more for determination of the chemical oxygen demand （cod） of the water method, the oxidation method is the most common, but this method also has some disadvantages, following the water quality detection index made a analysis for everyone in the detection of water quality as the reference standard, following the water quality detection index made a analysis for everyone in the detection of water quality as the reference standard.
