消毒剂副产物在地下水环境中行为研究进展

Research progress on the behavior of disinfectant by-products in groundwater environment

消毒剂副产物在地下水环境中的行为研究对水资源保护具有重要意义,在归纳总结目前已有国内外研究的基础上,对消毒剂副产物的种类特征、生成机制及在地下水环境中的行为进行讨论。明确了地下水环境中消毒剂副产物的来源及在地下水环境中迁移转化行为。消毒剂副产物在地下水环境中迁移转化不仅受多孔介质参数、水化学条件、水动力学条件的制约,还受地下水环境中的胶体、有机物含量等因素影响。并对近年来研究进展进行简要概括,目前消毒剂副产物在地下水环境中行为研究日益丰富,但由于地下水环境的复杂性,消毒剂副产物的多样性,对消毒剂投加阈值以及地下水环境中消毒剂副产物的去除仍需进一步探讨。

Understanding the behavior of disinfectant by-products in groundwater environment is of great significance to protect water resources.On the basis of the previous research at home and abroad,the characteristics,generation mechanism and behavior of disinfectant by-products in groundwater environment were discussed.The source of disinfectant by-product and its migration and transformation behavior in groundwater environment were clarified.The migration and transformation of disinfectant by-products in groundwater environment was not only restricted by porous media parameters,hydrochemical conditions and hydrodynamic conditions,but also affected by factors such as colloid and organic matter content in groundwater environment.The research progress in recent years was summarized briefly.At present,there were more and more studies on the behavior of disinfectant by-products in groundwater environment.However,due to the complexity of groundwater environment and the diversity of disinfectant by-products,the threshold of disinfectant addition and the removal of disinfectant by-products in groundwater environment still need to be further discussed.
