阿姆斯特丹试验“气泡屏障”清理河道

    Amsterdam is testing a "bubble barrier" to help remove plastic from the city's waterways.
    阿姆斯特丹正在测试一种气泡屏障,以帮助清理该城市河道中的塑料垃圾。

    The project is called the Great Bubble Barrier. The system aims to capture waste beneath the surface of the water. The city launched the effort in November. The non-profit group supporting the project hopes it can be used in other places if successful.
    这项工程被称为大气泡屏障。该系统旨在捕获水表以下的塑料垃圾。该市于11月启动了这项措施。支持该项目的非营利性组织希望如果它能取得成功,可以在其它地方投入使用。

    Francis Zoet is the technical director of the Great Bubble Barrier project. She told Reuters, "A bubble barrier is basically a tube that we place on the bottom of the river or canal, that has holes in it and we press air through it; that creates a bubble curtain."
    弗朗西斯·佐特是大气泡屏障项目的技术总监。她对路透社表示:“气泡屏障就是在河道底部铺设有孔的管道,然后向管道注入压缩空气,就会形成一道气泡帷幕。” 

    The tube lies diagonally across the canal. The bubbles work with the flow of water in the canal to float the waste and then move it into a collector on the side.
    这些管道斜穿河道。气泡与河道中的水流共同作用,使塑料垃圾漂浮起来,然后把它们移动到一侧的收集器中。

    The bubbles do not interfere with passing boats. They also do not cause a major problem for fish or birds.
    这些气泡不会干扰过往船只。它们也不会对鱼类或鸟类造成重大问题。

    Amsterdam already has four boats that collect about 42,000 kilograms of plastic a year. But the boats can only pick up the waste on the surface. They miss some smaller pieces altogether.
    阿姆斯特丹已经拥有四艘船,它们每年可以收集4.2万公斤塑料垃圾。但是这些船只能收集河道表面的塑料垃圾。它们会彻底遗漏一些小块的垃圾。

    Roy Leysner is with Waternet, part of the local water authority that is paying for the project with the City of Amsterdam. He told Reuters, "Every piece of plastic which falls into the water in the canals is eventually flowing out to the North Sea. We want to prevent that."
    罗伊·莱斯纳就职于地方水务局下属的Waternet,该部门与阿姆斯特丹市政府一同为此项目出资。他对路透社表示:“每块落入河道的塑料最终都会流入北海。我们要避免这种情况。”

    The Helmholtz Centre for Environmental Research in Germany estimates that rivers carry up to 4 million metric tons of plastic into the world's oceans each year.
    德国亥姆霍兹环境研究中心估计,全球每年有高达4百万吨塑料通过河流进入大海。

    Another Dutch group has also launched a system to collect surface-level river waste using floating barriers.
    另一家荷兰机构也启动了使用浮动屏障收集河道表面垃圾的项目。

    Zoet of the Amsterdam project said the two ideas work well together. She said, "We support basically every initiative that is focused on reducing the plastic soup."
    阿姆斯特丹项目的佐特表示,这两种创意很好地融合到了一起。她说:“我们支持各种旨在减少海洋塑料垃圾的举措。”
