摘　　要：针对煤化工企业所产生的膜浓缩废水进行盐质分离研究,此种废水主要成分为盐、硝,尝试采用盐硝分离的方法来把废水中的盐、硝分离开来,最大限度减少此种废水对环境的污染,同时资源化利用了废水中的Na Cl、Na_2SO_4,为企业创造一定的经济效益。We conduct a salt separation analysis on the membrane concentration waste water which generated from coal chemical industry. This kind of waste water mainly consists of salt and saltpeter. We try to separate the salt and saltpeter through the method of production of salt products. This method can maximally reduce the pollution which comes from this kind of waste water, and at the same time, bring some economic benefits for the industries since the NaCl and Na2SO4 in the waste water have been utilized.
