摘要
总有机碳(TOC)能较全面地反映水体中机物的污染程度,而且TOC测定仪操作简单,数据准确。以曝气生物滤池(BAF)再生水工艺为研究对象,对低基质浓度水样的TOC和CODCr测定值进行了相关性研究,在本试验条件下得出了如下关系式:CODCr=7.2778TOC-31.946,相关系数r=0.9674,为BAF再生水工艺中以TOC值代替CODCr值,简化检测手段提供了参考。
TOC can reflect organic pollution of water more completely,and TOC measuring apparatus is easier to be operated and got accurate data. The interrelationship between TOC and CODcr of low concentration substance in BAF process of water reuse was studied in this paper. A function was gained in this condition：COD = 7. 2778TOC - 31. 946,coefficient r = 0. 9674. The function may get used in daily on-line monitoring and made testing method handier.
