摘要
对微塑料的污染来源与生态风险进行了介绍,根据国内外微塑料的去除技术的研究,综述了过滤、混凝、电絮凝、密度分离、生物捕食、化学消化六种去除技术,分析比较了各种去除技术的去除率和优缺点,并对今后研究应用从实验室走向实际工程应用进行展望,进一步说明了混凝-絮凝法的去除效率较高;不同技术组合使用,以提高污水中微塑料去除的效果及稳定性是将来研究重点。以期对未来污水中微塑料颗粒的高效去除技术的研发提供一些帮助。
The paper provides an introduction to the pollution sources and ecological risks of microplastics,and reviews six removal techniques based on domestic and international research on microplastics removal technologies:filtration,coagulation,electroflocculation,density separation,biological predation and chemical digestion,analyses and compares the removal rate,advantages and disadvantages of various removal techniques.The paper also provides an outlook on future research applications from laboratory to practical engineering applications,further demonstrating that coagulation-flocculation has a higher removal efficiency;and the combination of different techniques aiming at improving the effectiveness and stability of microplastics removal in wastewater will be the focus of future research.It is expected to provide some assistance to the future development of efficient removal technologies for microplastic particles in wastewater.
