摘　　要：备受全球关注的微塑料污染现象近年来在我国的研究方兴未艾,污水处理厂被视为微塑料的集中区和出口,成为研究微塑料的热点。因此,本研究以污水处理厂为研究对象,通过采用扫描电镜等技术对进出水口的微塑料进行详细的溯源和解析。研究发现,微塑料主要集中在大污染源区,如生活垃圾和工厂排放口,然后通过雨水经雨水管道流入污水处理厂。而在污水处理过程中,活性污泥法等技术可有效去除微塑料,但是沉淀后的污泥含有大量微塑料,如果未经妥善处理,将再次造成微塑料污染。因此,除了要加强源头控制,高效和安全的污泥处理技术也是防控微塑料污染的重要手段。本研究不仅揭示了微塑料在污水处理厂的分布与演变特性,也提出了可行的微塑料控制路径,对于切实防止污水处理厂成为微塑料的“出口”具有指导作用。In recent years,the phenomenon of microplastic pollution that has attracted global attention is also in the ascendant in China.Sewage treatment plant is regarded as the concentration area and export of microplastics,and has become a hot spot in the study of microplastics.Therefore,this study uses the sewage treatment plant as the detailed traceability and analysis of microplastics by the inlet and outlet.The study found that microplastics are mainly concentrated in large pollution source areas such as household waste and factory discharge outlets,and then flow into sewage treatment plants through rainwater and rainwater pipes.In the process of sewage treatment,activated sludge method and other technologies can effectively remove microplastics,but the precipitated sludge contains a large number of microplastics,if not properly treated,will cause microplastic pollution again.Therefore,in addition to strengthening the source control,efficient and safe sludge treatment technology is also an important means to prevent and control microplastic pollution.The study not only reveals the distribution and evolution characteristics of microplastics in sewage treatment plants,but also puts forward a feasible control path of microplastics,which has a guiding role in preventing sewage treatment plants from becoming the“exit”of microplastics.
