各类污水处理工艺去除微塑料的原理及效果

Principle and Effect of Various Wastewater Treatment Processes to Remove Micro Plastics

污水处理厂是控制微塑料污染中非常重要的一环,因而研究各类污水处理工艺去除微塑料的原理及效果有着非常重要的意义。文章综述了目前最重要的污水处理工艺(絮凝沉淀工艺、生物反应器工艺、高级氧化工艺和膜过滤工艺)去除微塑料的原理及效果,分析了上述工艺在去除微塑料过程中存在的问题,并探讨了该领域未来可能的研究方向。

The sewage treatment plant is a very important part in the control of micro plastic pollution,so it is of great signif icance to study the principle and effect of various sewage treatment processes to remove micro plastic.In this paper,the principles and effects of the most important wastewater treatment processes(flocculation and sedimentation process,bioreactor process,advanced oxidation process and membrane f iltration process)for the removal of micro plastics are reviewed.The problems existing in the process of removing micro plastics by these processes are analyzed,and the possible research directions in this f ield are discussed.
