手动单兵海水淡化器的制淡实验研究

文章采用DB-Ⅰ型手动单兵海水淡化器对实验室配制盐水与几种实际海水进行脱盐实验,结果表明:盐水的含盐量与温度是影响操作压力、淡水量及水质的主要因素。盐水的含盐量越大,操作压力就越大,淡水的含盐量也越高;盐水的温度越低,淡水的含盐量也越低,但操作压力反而越大。从盐水的含盐量与温度对淡水量的影响来看,含盐量1%～4%的只相差0.3%,10～35℃时约相差7%;通过膜法一级反渗透即可获取符合GB5749-2006标准的饮用水。

Laboratory-scale Study on Single Soldier Hand Device of Seawater Desalination

DB-1 type seawater desalination device was used for laboratory scale study on various kinds of salt water prepared in laboratory and actual seawater.Results showed that concentration and temperature of salt water were the major affected factor of desalination operations.Higher the salt concentration was,higher the operation pressure and salt concentration of fresh water were.Lower the temperature of salt water was,less the salt concentration of fresh water and higher the operation pressure were.The effect o...
