Abstract

For ecological safety and public health, it is essential to identify the causes of pollution in water sources and the effects of both natural and human activities. A class of secondary pollutants known as disinfection byproducts (DBPs) is produced when water is treated with disinfectant. Global problems include DBP formation, monitoring, and health effects in drinkable water. Because of the negative health effects of drinking chlorinated water and some DBPs, water manufacturers have made an attempt to balance pathogen elimination with DBP monitoring. The primary obstacles to managing DBPs are their low concentrations and the viability of their extensive use from a technical and economic perspective. Adsorption on activated carbons, ion exchange, membrane processes, and reducing precursors like NOMs are some of the techniques that may be used in controlling DBPs. The application of both new and conventional disinfection technologies in the removal of ARB and ARGs is also summarized in this review, with an emphasis on bacterial inactivation mechanisms like ozonation, chlorination, ultraviolet (UV), sunlight, sunlight-dissolved organic matter (DOM), and photocatalysis/photoelectrocatalysis (PEC).

水消毒及消毒副产物

为了生态安全和公众健康，必须查明水源污染的原因以及自然活动和人类活动的影响。当水用消毒剂处理时，会产生一类称为消毒副产物（DBPs）的二次污染物。全球性问题包括饮用水中DBP的形成、监测和健康影响。由于饮用氯化水和某些DBP对健康的负面影响，水制造商试图平衡病原体消除与DBP监测。从技术和经济角度来看，dbp管理的主要障碍是其浓度低和广泛使用的可行性。活性炭吸附、离子交换、膜过程和还原前体如NOMs是一些可能用于控制DBPs的技术。本文综述了新型和传统的消毒技术在去除ARB和ARGs中的应用，重点介绍了臭氧化、氯化、紫外线（UV）、日光、日光溶解有机物（DOM）和光催化/光电催化（PEC）等细菌灭活机制。图形抽象

期刊介绍： Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
