摘要
微塑料对生物体具有毒性,自然水体和土壤中微塑料的重要来源之一是城市污水的排放及污泥的处置。阐述了城市污水中微塑料的来源、主要类型及其危害、处理方法、分析方法等。在污水处理过程中,不同水处理单元对微塑料的去除效果不同,密度和粒径也是影响去除率的重要因素。提出应加强控制微塑料源头、深入研究微塑料的去除工艺、规范微塑料取样及检测等过程。
microplastics are toxic to organisms,one of important sources of microplastics in nature water and soil is urban sewage discharging of and sludge disposing.The sources,main types and hazards of microplastics in urban sewage were summarized with the treatment methods and analysis methods elaborated at the same time.In sewage treatment process,different water treatment units have different removal efficiency on microplastics,in which the density and particle size of microplastics are also important factors affecting the removal rate.It was pointed out that,the control of microplastics sourcing should be strengthened,microplastics-removing technologies should be deeply studied,and more than that,standardized microplastics sampling and testing processes were also required.
