COD与TOC是表征水体中有机污染程度的指标。为全面掌握水样中的有机污染量，探索性地研究了城市生活污水中的COD与TOC的相关性，对南京市5家城镇污水处理厂污水的COD与TOC进行了综合分析与计算。结果表明，COD与TOC的线性关系显著，可根据TOC值在一定范围内推算COD值。

COD and TOC are factors representing the degree of organic pollution in water body. In order to grasp the organic pollution in water samples comprehensively, exploratory research on the correlation of COD and TOC in urban sewage are carried out, so are the comprehensive analysis and calculation on COD and TOC of five urban wastewater treatment plant in Nanjing. The results show that COD and TOC have obvious linear relationship, COD value can be calculated based on the TOC value within a certain range.
