摘要
微塑料是直径<5 mm的塑料碎片或塑料颗粒,作为一种新兴的持久性污染物,严重影响水生态健康及供水安全。而现有的处理技术尚无法完全去除水中的微塑料。随着环境污染问题的日益严重,有关微塑料的来源、特性、迁移转化规律等研究备受关注。对微塑料的来源及在水环境中分布情况进行介绍,综述了微塑料在污水和给水处理厂中的迁移规律和去除特性,分析不同工艺对微塑料去除效能的差异,探讨了常规混凝技术、溶胶-凝胶技术、电絮凝技术、膜技术和磁分离技术等去除技术的研究进展,并展望微塑料污染水体净化的研究方向。
Microplastics are plastic pieces or plastic particles with a diameter less than 5 mm.As a new emerging persistent contaminant,microplastics seriously affect water ecological health and water supply security.However,current treatment technologies are unable to completely remove microplastics from water.With the increasingly serious environmental pollution,researches on sources,characteristics,migration and transformation behaviors of microplastics have attracted growing concerns.The source and distribution in water environment of microplastics were introduced.The migration behaviors and removal characteristics of microplastics in wastewater and water treatment plants were reviewed.The removal efficiency by different water treatment processes was discussed.The methods for removing microplastics including coagulation,sol-gel method,electrocoagulation,membrane technology,magnetic extraction were concluded.And the intends to provide frontier reference to further investigation were provided.
