| 摘 要： | 以确保沿海地区工艺用水性能、节约淡水为目标,提出了一种制作淡化海水新工艺。依据电渗析原理,制作小型便携的隔膜电渗析及电解装置,通过2级(或以上)双隔膜电渗析器和隔膜电解器相配合的方法实现对海水的淡化处理,既能更好地进行脱盐,又使生成淡水有较高pH值,提高了水的活性,有利于冲洗海砂等工艺用水要求。用U-I曲线法测试了双隔膜渗析电解器的极限电流,并由此确定各级电解的工作电流。模拟海水淡化试验结果表明,一级流量为100 mL/s左右时,淡化模拟海水(含盐量15 g/L)生成的淡水已符合冲洗海砂等工业的要求(含盐量≤800 mg/L),pH值9.5左右。将之用于海砂冲洗,可以提高清洗效果,实现既节省河砂又节约淡水的目的。
