摘　　要：系统地对比了COD和TOC两种水中有机污染指标测定方法原理,得出了TOC在直接代表水质有机污染、氧化有机物完全、产生二次污染物少、测定时间短和消耗劳动力少等方面优于COD的结论,并分析了TOC取代COD的难点和趋势。In contrast with COD,TOC is better to reflect the organic pollution of water.It was apparent from the principles of COD and TOC that the oxidation of organic pollutants is more complete in TOC than COD. TOC produce less secondary pollution,needs shorter analysis time and consumes less labor than COD.Also,the difficulties and the trend of TOC replace of the COD were analyzed.
