| 摘 要： | CODcr和TOC均是表征水体有机污染程度的指标,对于一般有机废水,理论上两者线性相关。采用线性回归法对冶金钢铁行业废水中TOC和CODcr两项指标的监测数据进行统计分析,建立CODcr对TOC的转换方程,并用相关系数法进行显著性检验。结果表明冶金钢铁行业废水中CODcr值和TOC值的线性关系显著,建立的一元线性回归方程的准确度可以满足水质监测的需要,在一定条件下可以使用TOC监测值间接换算CODcr值。

| Abstract: | Both CODcr and TOC can reflect the organic pollution of water quality.Theoretically,there is linear dependence between CODcr and TOC of common organic wastewater.Linear regression method had been used to analyze the TOC value and CODcr value monitored in iron & steel industry wastewater.Thus the TOC-CODcr transformation equation had been established.Under specified conditions this transformation equation can be used to transform TOC monitoring value to CODcr. |
