美国取得海水淡化技术新突破
美国 海水 淡化技术
2017/9/8
淡水资源的严重匮乏威胁着全球数以亿计的平民生存。近日，美国得克萨斯州莱斯大学纳米技术水处理中心（NEWT）表示，已经掌握了利用太阳能淡化海水的关键性步骤，在海水淡化技术上取得重要突破。新的研究已经发表在美国国家科学院学报上。此项目由美国莱斯大学纳米技术水处理中心领导，相比传统方法，团队研究人员将特殊的纳米颗粒加入到蒸馏膜中，将太阳能即时转变为热能（自加热），因此不再需要额外能源使水沸腾。热盐水沿着...

土地使用变化提高城市水处理成本
土地使用变化 城市水处理
2016/7/27
近日，刊登在美国《国家科学院院刊》上的一项研究揭示，水流域土地使用的变化使得全世界近1/3城市的水处理成本增加了约一半。一般而言，城市水处理成本取决于水源的水质。城市化已经改变了人们在城市水源流域内的土地使用情况，而建立这些变化与水处理成本间的联系十分困难。大自然保护协会的Robert McDonald及其同事，通过把人口增长和土地使用变化的数据结合起来，并使用新构建的详述309个大城市水源位置的...
