高密度澄清技术在低温低浊度海水淡化预处理中的应用

Application of densadeg to the pretreatment of the desalting of seawater with low temperature and low turbidity

海水淡化是目前解决淡水匮乏问题的重要方法之一,为了节约海水淡化的成本,加强处理效果,进行适当的预处理是很有必要的。在低温低浊度地区,传统的海水淡化预处理工艺很难解决由于海水的低温低浊度带来的水体中悬浮物和胶体难去除的问题。高密度澄清技术具有很多优良的特性。作者对用该技术预处理低温低浊度海水的效果进行了研究。

The desahing of seawater has been one of the most significant solutions to settle the problem of freshwater shortage. In order to save the costs and enhance the effect,proper pretreatment is very necessary. But in low- temperature and low-turbidity areas,the traditional pretreatments of desahing could not remove the colloid and suspend substance very well because of the low temperature and low turbidity. By virtue of the special character and configuration, densadeg has lots of excellent characteristics. This experiment intends to assess the effect of densadeg for treating this kind of seawater.
