The research aims at washing processes as possible sources of microplastics, specifical microfibers in wastewater, and the behavior of the virus particles SARS-CoV-2 in wastewater after the washing process as well as their ability to sorb to the surface of microfibers, released from washing processes. The conclusions of the research point to the ability of the virus to attach to possible solid impurities such as textile fibers (microfibers) occurring in the sewer and to the ability of wash water to influence their possible occurrence in the sewer. The highest efficiency (more than 99%) of removal virus particles was after washing process, using liquid washing powder, and washing soda. These findings may gradually contribute to a better understanding of the behavior of the virus particles in the sewer.
该研究旨在探讨洗涤过程作为微塑料（特别是废水中的微纤维）可能来源的情况，以及洗涤过程后废水中新冠病毒颗粒的行为，及其吸附到洗涤过程中释放的微纤维表面的能力。研究结论表明，病毒能够附着在下水道中可能存在的固体杂质（如纺织纤维（微纤维））上，并且洗涤水会影响病毒在下水道中的可能存在情况。使用液体洗衣粉和纯碱进行洗涤后，去除病毒颗粒的效率最高（超过99%）。这些发现可能会逐渐有助于更好地理解病毒颗粒在下水道中的行为。
