VOA常速英语:瑞典项目:尝试污水再利用

The Swede water’s full of nutrient that could be used to agriculture or fertilizers but it’s also full of toxicant materials that are not good for crops.
瑞典的水域中营养丰富，可用于农业或肥料，但同时也充满了不利于作物有毒物质。

And a new water treatment project being tested in Sweden seeks to retain the good elements from the waste water and eliminate the harmful ones.
瑞典正在进行的一项新的水处理项目试图从废水中保留好的元素，并清除有害物质。

Today we’ll mix the waste waters into one big pipe so we have the large flows from all the open areas in the city and then we have a lot of heavy metals and pollutants from cars and all the streets.
今天我们要把废水混合起来倒入一条大管子，所以我们就要从城市所有的开阔区域找到大量的污水，还有汽车尾气和街道上我们可以得到很多重金属污染物。

And it’s getting mixed with a beneficial factions from the toilet waste water because urine feces are really good fertilizers but we should not mix them with other waste waters from urban areas.
尿液中的废物是很好的肥料，但我们不把它们与城市的其他废水混合在一起。

Doctoral Chemical-Engineering student Hamse Kjerstadius devises a water treatment system that could increase biogas production, plant neutrality cycling and heat recovery.
化学工程博士学生Hamse Kjerstadius设计了一套水处理系统，可以提高沼气产量，进行中性水循和热回收。他的计划将在瑞典南部赫尔辛堡的一个正在建造中的新地区进行。

We will separate the waste water already at the source in the household so we have the toilet waste water into one pipe and the food waste into a separate pipe and the remaining household waste water,the grey water into a third pipe, so the three pipes living in the household and that means we can have a lot more efficient treatment to down hold the wasteful treatment plant and recover more resources from the waste water.
我们将根据家庭污水的来源把它们进行分类，我们把厕所污水导入一个管子中，再把厨房污水导入另一个管子中，最后把其他家庭污水导入第三个管子中，这种管理把家庭污水的方法将会有效地提高污水治理厂的效率，也可以从污水中重新得到更多可利用的资源。

The project is attracting attention as Swedish cities with older sources systems look for equal friendly upgrades.
此项目对瑞典的某些还在使用旧能源并寻求质量更加上乘的同等可代替能源的老城区来说很有吸引力。
