化学需氧量测定结果影响因素分析

DETERMINATION OF CHEMICAL OXYGEN DEMAND ANALYSIS OF THE RESULTS OF THE IMPACT OF FACTORS

化学需氧量是一个条件性的指标,分析中要严格按国家标准方法的要求做好实验条件的控制,按步骤进行,同时要考虑到对影响测定结果的因素控制和对水质样品性质进行分析,使测定结果能够反映水质样品的实际,为环保管理和装置运行提供可靠的数据。

Chemical oxygen demand is a condition of the indicators,the analysis should be in strict accordance with the requirements of national standard method of control of experimental conditions to do a good job,according to the steps,taking into account the results of the determination of the factors that affect the control and the nature of water quality samples for analysis,so that results can reflect the actual water samples for the environmental management system and device to provide reliable data to run.
