摘    要:对UV254进行了不同于传统认识的探讨,揭示了其在水处理中与TOC、DOC,以及THMs前驱物等常用有机物控制指标之间的相关关系,并通过可行性探讨说明UV254可以作为它们的替代参数。UV254的测定具有仪器便宜、操作方便、使用成本低、与原指标相关度高、精度高和重复测定重现性好等优势。在目前国内水处理厂运行监控以及实验室研究条件下,UV254作为有机物控制的间接参数,具有重要的应用价值。

关 键 词:测定  TOC  腐殖质  UV254  水处理  有机物

Abstract:Through the discussion from a view different from the traditional, the correlations between UV 254 and organic matter monitoring parameters in the field of water supply and wastewater treatment was discussed, such as TOC, DOC and THMs precursors. According to the explanation of applicability in this paper, UV 254 can be used as a surrogate parameter. The measurement of UV 254 as a surrogate parameter has several advantages, such as inexpensive instrument, convenient operation, low operating costs, good correlations to the parameters surrogated, high accuracy and excellent data reappearance in multiple measurements. The application of UV 254 as an indirect parameter is quite valuable, especially under the current financial level of the operation and monitoring of the water and wastewater treatment plants and the laboratory research in China.
Keywords:UV    254  measurement of organic matter  surrogate parameter  humus
