纺织印染废水中TOC值和COD值的相关性

The Correlation of TOC Value and COD Value in Textile Dyeing Wastewater

论证了纺织印染废水中TOC值和COD值的相关性,建立了COD和TOC的相关关系式。通过对实测的TOC值和COD值进行的一系列数理统计显著性检验,证实了纺织印染废水中TOC值和COD值之间具有良好的相关性,但基于生产过程、设施装置和排污情况的差异,印染企业在运用COD和TOC的相关关系式时,应根据自身的具体情况,通过实验建立相应的回归方程。

To study the correlation of TOC value and COD value in textile dyeing wastewater and establish their correlative equation. After mathematical statistic test of significance was undertaken for the detection value of TOC and COD, it was confirmed that there had good correlation between TOC value and COD value in textile dyeing wastewater. Because of the difference of each productive process and equipment and pollutant discharge, it should establish relative regression equation when to use the correlative equation.
