Chemical oxygen demand ( COD ) is a synthetical indicator which represents the degree of organic pollution in water. 化学需氧量(OD)(COD)是表征水体中有机物污染程度的一个综合性指标。
Discussion on Determination Method of the Chemical Oxygen Demand(OD) in Water and Waste Water 水和废水中化学需氧量(OD)测定方法探讨
The standard Determination of the chemical oxygen demand is dichromate method, with the most widespread application. 测定化学需氧量(OD)的标准方法是重铬酸盐法,应用最为广泛。
But the body's cells continue functioning at a high metabolic rate, keeping oxygen demand high. 但是同时机体的细胞仍然以高代谢率维持细胞功能。
The biochemical oxygen demand was determined by the speedy testing method of microorganism sensor. 利用微生物传感器快速测定水中生化需氧量(OD)。
