據(jù)外媒報道，比利時根特大學(xué)科學(xué)家發(fā)明一種用太陽能把尿液變飲用水和肥料的機器，相關(guān)技術(shù)可用在農(nóng)村和發(fā)展中國家。
廢水凈化方式有多種，然而本次根特大學(xué)（University of Ghent）研究系統(tǒng)采用一種特殊的薄膜，不但符合能源效率，還可應(yīng)用在供電困難地區(qū)。
據(jù)報道，根特大學(xué)研究員德瑞斯（SebastiaanDerese）稱，使用太陽能，經(jīng)一個簡單過程，就可把尿變肥料和飲水。
研究人員先用大水塔集尿，再用太陽能鍋爐加熱，然后液體流過薄膜時，會把鉀、氮、磷等成分分離出來，并將水還原。
部分原文報道如下：
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.
