| 中文摘要 |
| 微塑料作为一种新污染物,因其分布的广泛性和潜在的生物毒性在环境研究中引起了高度关注. 饮用水处理厂是保障居民用水安全的关键设施,其对微塑料的去除效能引起了极大关切. 水厂中不同的水处理工艺在微塑料去除方面表现出差异化的效能,具有不同的去除机制. 为了全面分析饮用水处理厂对微塑料去除效能与机制,首先着眼于国内外饮用水处理厂进出水中的微塑料丰度及其去除率,接着综述了混凝/絮凝-沉淀、砂滤、膜滤和消毒这4种常用的处理工艺对微塑料的去除效能及机制. 同时,指出了现有研究存在的不足和未涵盖的领域. 最后,归纳总结了终端自来水中的微塑料含量和人类暴露量的评估情况,并从标准化取样检测方法、纳米塑料检测、给水系统微塑料释放和风险评估等角度展望了未来的研究方向. |
| 英文摘要 |
| Microplastics, as a novel type of environmental pollutant, have attracted notable attention in environmental research due to their widespread distribution and potential biological toxicity. Drinking water treatment plants play a crucial role in ensuring the safety of the water supply, with a particular focus on the removal efficiency of microplastics in drinking water treatment plants. Different treatment processes in water plants exhibit various removal efficiencies of microplastics and they operate through distinct removal mechanisms. To comprehensively analyze the removal efficiency and mechanism of microplastics in drinking water treatment plants, this study first examined the abundance and removal efficiency of microplastics of the influent and effluent of drinking water treatment plants. Subsequently, this study reviewed the removal efficiency and mechanism of four commonly used treatment processes： coagulation/flocculation/sedimentation, sand filtration, membrane filtration, and disinfection. The shortcomings and gaps in current studies were also pointed out. Finally, the assessment of microplastics abundance and human exposure in tap water was summarized and the future research direction was prospected from the perspectives of standardized sampling detection methods, nanoplastic detection, microplastics release in water supply systems, and risk assessment. |
