摘要
利用大量CODCr、色度、浊度的监测数据,初步探讨了造纸废水中色度与CODCr的关系。结果表明,浊度较低(≤2NTU)时,具有发色基团的有机溶解性分子对COD贡献率较高,色度—CODCr公式可以较准确的估计CODCr值;随浊度升高(>2NTU),公式估计值的相对标准偏差呈现近似直线的上升态势,必须考虑色度和浊度两个影响因素。
With a great deal of measuring data of CODcr, chroma and turbidity, the relationship between chroma and CODcr of paper mill effluent was preliminarily investigated. The results showed that when the turbidity was low （≤2NTU）, the contribution rate of organic solubility molecular with chromophoric groups to COD was relatively high, and CODcr was positively correlated with chroma; when the turbidity was high （〉2NTU）, the relative standard deviation of formula estimated value was in an increasing tendency approximate to straight-line, so chroma and turbidity influencing factors must be considered simultaneously.
