< p >我最近看< a href = " https://www.youtube.com/watch?v = bfr82RB72U8 " rel = "这个视频nofollow noreferrer " > < / >关于海水淡化工作在世界各地和海水淡化的可行性来为人类提供淡水。我有几个问题:< / p > < p > 1 -他们提到的盐水释放过程的副产品对海洋生物有害,所以为什么不就把它倒在沙漠中呢?为什么我们需要释放在海洋吗?我相信这不会是大的影响考虑到海水淡化是一个小比例的世界水生产。如果任何,鉴于全球海平面正在上升,这可能帮助的事情,对吧?< / p > < p > 2 -视频状态,绝大多数的海水淡化厂这些天使用反渗透海水淡化,而不是heat-based方法。为什么是这样呢?这一过程需要能量比如何使用太阳能蒸发水吗?< / p > < p > Heat-based方法需要来自太阳的能量,是的。 But the way I imagine things, we can passively let in water from the ocean, put it under some glass panel that magnifies sun energy, and then let the water evaporate out through some piping to condense somewhere else. How is powering a pump through a membrane (that requires cleaning after) better?
A lot of these thoughts are just me thinking out loud with no data to back me up because honestly, I wouldn't know what to look up regarding things like this. I'd love some science-based replies to this! I'm definitely missing something big.
