Abstract This review highlights the methodologies for sampling, sample preparation, and identification of microplastics found in wastewater treatment plants. The presence and deposition of microplastics in the environment lead to serious environmental and ecological concerns. The role of wastewater treatment plants in spreading microplastics to the environment poses additional threats that need to be treated. Thus, the key challenges remain in understanding the fate and occurrence of microplastics in the wastewater treatment plant and the ability to detect them at each stage of the treatment. This review, therefore, helps to understand the fate and occurence of microplastics in the wastewater treatment plant. Besides, it is organized to present an overall discussion of the available microplastics detection techniques from sampling to identification.

污水处理厂中的微塑料：发生、归宿和识别

摘要 本综述重点介绍了污水处理厂中发现的微塑料的取样、样品制备和鉴定方法。微塑料在环境中的存在和沉积导致了严重的环境和生态问题。废水处理厂在将微塑料扩散到环境中的作用带来了需要处理的额外威胁。因此，关键挑战仍然在于了解微塑料在废水处理厂中的归宿和发生情况，以及在处理的每个阶段检测它们的能力。因此，本综述有助于了解微塑料在废水处理厂中的归宿和发生情况。除了，
