【摘要】 采用两级(或以上)双隔膜电渗析和隔膜电解相配合的方法淡化海水,生成符合冲洗海砂要求的工业淡水。所得淡化海水属于碱性电位水,有较高的pH值,可以提高清洗效果。采用堆砂冲洗法,用充足的淡化海水(碱性电位水)冲洗海砂,提高了冲洗效果,达到节约河砂与淡水的目的。冲洗后的海砂含有一定的OH-离子,有利于减小海砂混凝土液相中Cl-/OH-的比值,可进一步抑制Cl-离子侵蚀,提高海砂混凝土耐久性。更多还原

【Abstract】 With two(or more)dual diaphragm membrane electrodialysis and electrolytic desalination matching method to generate consistent with the requirements of industrial sand washing water.Income potential of seawater desalination is alkaline water,have a higher pH,can improve the cleaning effect.Of sand washing method used,with plenty of desalinated water(alkaline potential of water)washed sand to improve the washing effect,to save the purpose of river sand and fresh water.After washing the sand contains a certain degree of OH-ions,which is conducive to reduce the ratio of liquid Cl-/OH-and can further inhibit the Cl-ion erosion,which would improve the durability of concrete.更多还原
