食品伙伴网讯 据外媒报道，比利时根特大学科学家发明一种用太阳能把尿液变饮用水和肥料的机器，相关技术可用在农村和发展中国家。
废水净化方式有多种，然而本次根特大学（University of Ghent）研究系统采用一种特殊的薄膜，不但符合能源效率，还可应用在供电困难地区。
据报道，根特大学研究员德瑞斯（SebastiaanDerese）称，使用太阳能，经一个简单过程，就可把尿变肥料和饮水。
研究人员先用大水塔集尿，再用太阳能锅炉加热，然后液体流过薄膜时，会把钾、氮、磷等成分分离出来，并将水还原。

A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries.
While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid.
“We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy,” said University of Ghent researcher Sebastiaan Derese.
