近年来，海洋中微塑料(MPS)的增加已被列为可持续发展目标(SDGs)中的海洋污染之一。由于MPS漂浮在海洋中时会吸收有害化学物质，吃了吸收的MPS的小鱼可能会消化不良，健康状况不佳。为了解决海洋污染问题，必须提出一种高处理速度和高MP收集能力的好的MP收集方法。而近年来，产生高于15T磁场的第二代高温超导(HTS)磁体的性能得到了改善。这样的高场超导磁体有望提高MP的收集性能。在本文中，我们提出了一种利用超导磁体从海水中收集MP的概念设计。为了评估器件的性能，我们开发了流体模拟和磁场模拟相结合的方法。仿真结果表明，在较高的磁场强度下，能够以较高的处理速度有效地采集MPS。
In recent years, the increase of microplastics (MPs) in ocean have been recognized as one of ocean pollution listed in Sustainable Development Goals (SDGs). Since MPs absorb harmful chemicals while floating in ocean, small fish which eats the absorbed MPs may fall into bad digestion and poor health condition. To solve the ocean pollution problem, a good MP collection method must be proposed with a high processing speed and a high MP collection ability. While, recently, the performances of 2nd generation high-temperature superconducting (HTS) magnets which can generate a field higher than 15 T have been improved. It is expected that MP collection performances are enhanced with such high field superconducting magnets. In this paper, we propose a conceptual design for MP collector from seawater using superconducting magnets. To evaluate the performances of the device, we developed a fluid simulation coupled with magnetic field simulation. The simulation results indicate that MPs can effectively be collected with a high magnetic field with a high processing speed.
