摘　　要：以8%氯化铵+7%甘氨酸溶液为模拟废水进行电渗析脱盐研究,考察了脱盐速率、能耗以及甘氨酸的回收率。结果表明,电渗析可以有效的脱除废水中的盐,并在浓室得到浓度较高的氯化铵溶液。当操作电压为10 V时,脱除每公斤氯化铵的电耗为1.01 kWh,相应电流效率91.4%,甘氨酸回收率达到0.857。The desalination of 8%ammonium chloride+7%glycine solution by electrodialysis was studied.The desalination rate,energy consumption and glycine recovery were investigated.The results show that electrodialysis can effectively remove the salt from wastewater,and obtain high concentration ammonium chloride solution in the concentration chamber.When the operating voltage is 10 V,the power consumption per kilogram of ammonium chloride is 1.01 kWh,the corresponding current efficiency is 91.37%,and the glyphosate recovery is 0.857.
