电渗析法处理丙烯腈废水的研究

为了去除丙烯腈废水中的硫酸铵,采用电渗析法对丙烯腈废水进行脱盐处理。脱盐率随流量的升高而降低,随电压的升高而升高,但达到一定值后,脱盐率基本不随电压的变化而变化。流量升高,能耗降低;电压越高,能耗越高。在电压为10V、流量为50L/h的条件下,具有较好的电渗析效果,能耗在16.81kJ/g左右,温度提高有利于电渗析过程的进行。实验结果表明,该法切实可行。

Study on the treatment of acrylonitrile wastewater by electrodialysis

Electrodialysis has been used for eliminating ammonium sulphate from acrylonitrile wastewater.The de-salting rate decreases with the rise of flow rate,and increases with the rise of voltage.But when it gets to a certain point,the desalting rate basically does not change with the change of voltage.The flow rate increases when the ener-gy consumption decreases.The higher the voltage is,the higher the energy consumption.When the voltage is 10 V,and the flow rate is 50 L/h,the electrodialysis effect is better.The energy consumption is about 16.81 kJ/g.The ris-ing of temperature is good for carrying on the process of electrodialysis.The results show that this method is really feasible.
