浓海水化盐精制工艺实验研究

Study on the Refining Process of Desalination Seawater

利用海水淡化产生的排浓海水化盐,对精制工艺进行了研究。研究结果表明:所选三种工艺技术路线,以两次化盐-三次精制工艺为最佳,其排废浓海水的盐份利用效率高,盐水精制效果好;该工艺实施,减少了碱液的消耗,降低了废盐泥的数量,更易操作。

The refining process was studied by concentrated seawate,which was produced by desalination of sea water. The results show that the process of two times of salt- three refining was the best in the three processes. In this process,the salt utilization efficiency of waste concentrated seawater was high and the effect of refining was good. Meanwhile,the consumption of alkali liquor and number of waste salt sludge decreased. The process was easier to operate than others.
