摘要

本文采用UV/NH2Cl工艺对硫噻唑（STZ）的降解进行了研究，并检测了消毒后消毒副产物（DBPs）的形成。UV和NH2Cl工艺对STZ的去除具有协同作用。天然有机物和CO32−抑制STZ的降解，NO3−促进STZ的分解，而NH2Cl浓度、HCO3−和Cl−对STZ的去除具有双重作用。UV/NH2Cl对STZ的去除受pH的影响较小。活性氯和活性氮对STZ降解的贡献显著高于HO·。通过分析中间产物，提出了STZ可能的降解途径。此外，在NH2Cl或NaClO消毒过程中，UV/NH2Cl的预处理显著减少了DBP的形成。总之，UV/NH2Cl工艺是一种有效的水处理技术，具有良好的应用前景。

期刊介绍： Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
