摘要
水环境中总有机碳(TOC)可以反映水环境有机污染程度,是描述水环境质量状况的重要指标。通过探讨实际生产生活废水、天然水环境中TOC组分来源,梳理TOC检测技术方法,分析了红外吸收法、紫外—可见光谱等各项技术的优势及影响因素。目前TOC指标的研究应用领域集中在时空分布特征、与其他水环境指标关联性研究、水环境有机质降解途径等方面,结合现有研究成果提出了水环境TOC检测应用研究前景。
Total organic carbon(TOC)in water environment can reflect the degree of organic pollution in water environment,and it is an important indicator to describe the quality of water environment.The advantages of infrared absorption method,ultraviolet visible spectrum were analyzed by combing the TOC detection methods,the influencing factors in the TOC detection process were summarized and the sources of TOC components in the actual production and domestic wastewater and natural water environment were discussed.The research and application fields of TOC indicators focus on the characteristics of temporal and spatial distribution,the correlation between TOC with other water environment indicators,and the degradation pathways of organic matter in the water environment.Combined with the existing research results,the research prospects for the application of TOC detection in the water environment were proposed.
