due to micro plastics very difficult from ring in remove, therefore most to 广泛 关注. currently, separation and is water in micro plastics main/primary methods. is, this is 不切实际, is device easy and need 定期清洁 or more 换. issues is, can can small 于0.3 mm (网眼浮游生 material 净孔径 large small) 东西. this is 不幸, is 引起破 bad large more micro plastics ratio this type of plastics small, for and material system effect/influence 未知.

already design types has front 途 收集 this type of micro plastics new methods, methods utilizing will it 们收集 in water in. design manufacturing 一 体声波(BAW) plant/unit, plant/unit can micro plastics, will it 们收集 in in 间通道 in, water from 两侧通道 in 流出. this research is in textile and technology 学院专门 from ring analysis 森浩弘教授问 to research as 者秋山芳武副教授 is from engineering degree solution water in micro plastics.

research 人员关注 事实 is, 我们海洋 in most large micro plastics 源之一 is machine. type machine 每100 rise cycle 排放约一万根 fiber. many 衣服都 is use chemical fiber made formed, fine small plastics fiber sheet/slice in machine in 脱落. waste water 处理厂 currently method micro plastics.

research 人员决定创建一 types through pressure electrical 振动收集 micro plastics and micro plastics fiber equipment. through combined micro plastics long degree, and can pressure shrink property force and use 声音, 碎屑会 poly in 三通道 equipment in 间. 侧面 两 通道排出清洁 water, micro plastics fiber poly in in 间, utilizing pressure electrical parts 进行声学 poly 焦, from generate 声驻波. different type type micro plastics tool has different type type density, modulus and can pressure shrink property, this different comparison degree (ACF). through will micro wide degree selection is water in long semi, can make pellets poly in tube/pipe in 间. large 约花 0.

research in is 实验准备 micro plastics to 麻烦: very difficult manufacturing combined dimensions micro plastics. most 初, 他们尝试 use mixed combined machine will fiber formed same long degree, plastics fiber method 切割. through textile 部门 同事, research 人员发现 Kanehara绒毛 manufacturing 商, rear is provide research 需 材 material.

for/regarding 该实验, design 一 公式 计算针 for target/goal micro plastics fiber nylon 6, PET and polystyrene (PS) micro most poly 焦. rate non high, 当不考虑 viscous in upper most small pellets 时, PET rate is 95%, nylon 6 收集 rate is 99%. 流体动 force make fiber for 齐, from make BAW equipment 避免堵塞. use analysis soft parts pellets. is will 改进, can through use make coarse degree most small and retardant viscous methods generate micro surface.

实际 application and can shrink property 需 改进包括 use more tool has different 直径 串行 and 并行通道, strong/high made has type type micro plastics. through add more 通道(7 三叉通道, 意味 3 and other 于7 幂), can will 100 rise water milli force concentrated shrink is 50 mL, this very easy or 燃烧. research use application in most large concentrated degree micro property fiber. currently 实施 限 made is consumption process will very long time.

through this research, 捕获 直径 is 15μm PS珠, upper, 该BAW equipment can 够捕获 PS珠 most small dimensions is 4.3μm. 修改BAW equipment can relatively small 珠子. waste water in large more micro plastics is 10μm, long degree is 2至200μm. BAW equipment can formed 功捕获此 type micro plastics. is 捕获直径 small 于100 nm nano plastics, 声流体 technology need 进一步 development.
