Abstract

The EU Drinking Water Directive (2020/2184) adds standards for new disinfection by-products (DBPs) such as haloacetic acids, chlorite, and chlorate, in addition to trihalomethanes and bromate. Therefore, the upgrade of water treatment plants (WTPs) to meet the new standards may be necessary. The objective of this study is to assess approaches for enhancing conventional WTPs to minimize the formation of these just regulated DBPs. Three key strategies are identified: (1) enhanced precursor removal; (2) alternative disinfection/preoxidation and (3) removal of already-formed DBP. The advantages and disadvantages of such strategies are discussed, considering the formation of other emerging, unregulated DBPs. Guidelines are presented to select the most appropriate treatment trains that are proposed to upgrade the conventional WTPs.

升级水处理列车，以符合（欧盟）2020/2184 号指令引入的 DBPs 标准

欧盟饮用水指令》（2020/2184）增加了新的消毒副产物 (DBP) 标准，如卤乙酸、亚氯酸盐和氯酸盐，以及三卤甲烷和溴酸盐。因此，可能有必要升级水处理厂 (WTP) 以满足新标准的要求。本研究的目的是评估提升传统水处理厂的方法，以最大限度地减少这些刚刚受管制的 DBPs 的形成。本研究确定了三项关键策略：(1) 强化前体去除；(2) 替代消毒/预氧化；(3) 去除已形成的 DBP。考虑到其他新出现的、未受管制的 DBP 的形成，讨论了这些策略的优缺点。还提出了选择最合适的处理列车的指导原则，建议对传统水处理厂进行升级。
