治愈身心的“废水” The healing powers of wastewater

坦率地说，今天这张美丽图片的来源是附近地热发电厂的废水池。虽然这听起来并不诱人，但冰岛的蓝色泻湖是该国游客最多的景点之一。诀窍是不要陷入废水的“浪费”部分。这里的水是干净的，总是在100°F左右徘徊，富含大量的二氧化硅，这正是由于工厂的工艺，使其变蓝和变硫的原因。这些矿物质和少量藻类被认为是对皮肤和整体健康非常有益的补品。

Let's be frank here, the origin of today's beautiful picture is a pool of wastewater from a nearby geothermal plant. While that may not sound enticing, Iceland's Blue Lagoon is one of the country's most visited attractions. The trick is to not get stuck on the 'waste' part of wastewater. The water here is clean, always hovers around 100° F, and is enriched with tons of silica—which is what makes it blue—and sulfur thanks to the plant's processes. Those minerals, along with a little algae, are believed to combine into a highly beneficial tonic for skin and overall well-being.
