摘要
化学需氧量在河流污染和工业废水性质的研究以及废水处理厂的运行管理中,是指标水体有机污染的一项重要指标,能够反应出水体的污染程度。作为重要的评价指标,需要保证其检测结果具有很高的可信度。而检测结果的准确性和有效性,在很大程度上取决于其测量不确定度的大小。
Chemical Oxygen Demand is an important indicator of organic pollution in water body,which can reflect the pollution degree of water body,in the study of river pollution,industrial waste water property and the operation and management of waste water treatment plant.As an important evaluation index,it is necessary to ensure that its detection results have a high degree of credibility.The accuracy and validity of the detection result depend on the uncertainty of measurement to a great extent.
