养殖水中总有机碳与化学需氧量和生化需氧量相关性的研究

Study on the Correlation of Total Organic Carbon With Chemical Oxygen Demand and Biochemical Oxygen Demand in Water

摘要: 总有机碳能较全面地反映水体有机物的污染程度，总有机碳的测定具有操作简单、分析快速、结果准确等特点。研究了养殖水中的总有机碳与化学需氧量和生化需氧量相关性，总有机碳与化学需氧量的相关系数为０.９９１８，总有机碳与生化需氧量的相关系数为０.９３６２，可以用总有机碳来估算和衡量水体的污染情况。

Abstract: Total organic carbon (TOC) can reflect the water pollution situation perfectly. It has characteristics of simple operation, quick velocity, accurate result. This paper studied the relationship between total organic carbon (TOC) and chemical oxygen demand(COD_Cr) and biological oxygen demand(BOD₅) .The correlated coefficient of TOC and COD_Cr was 0.991 8 and that of TOC and BOD₅ was 0.936 2. That can be used to estimate the pollution situation in water.
