深圳市饮用水源中COD_(Mn)与TOC的相关性研究

Study on the pertinence between COD_(Mn) and TOC in the drinking source of Shenzhen

通过对深圳市饮用水源中CODMn和TOC测定结果的相关性分析,结果表明,水库内监测点位及监测区域CODMn与TOC相关性良好,水库外监测点位及监测区域CODMn与TOC相关性不显著,而整个监测区域的CODMn与总有机碳相关性令人满意。因此,提出了TOC值可直接作为饮用水源在线监测有机污染物的综合评价指标,同时也实现了湿式氧化法测定TOC在地表水监测中的应用。

It was indicated, there were better pertinence between CODMn and TOC in the spot and area of inside the reservoir, and there weren ＇ t better pertinence between CODMn and TOC in the spot and area of outside the reservoir , but there were better pertinence between COD~ and TOC in the entire area, by study on the pertinence between CODMn and TOC in the drinking source of Shenzhen. Thus TOC value can direct be used as evaluation target of organic pollutant of on-line detection in the drinking source, and the application of detecting TOC with the wet oxidation in the surface water were put forward.
