电吸附法处理炼化反渗透浓水脱盐研究

采用电吸附法对反渗透浓水进行处理,先研究了不同盐含量、电压、流量、初始pH等因素对NaCl模拟水去除效果的影响,得出适宜参数,再分别通过单级和多级电吸附法处理反渗透浓水,分析脱盐效果。结果表明,NaCl模拟水在初始电导率为2 mS/cm时,pH为7.56、电压1.8 V、体积流量10 mL/min时处理效果最优,单级脱盐率达到17.18%;反渗透浓水在初始电导率为2 mS/cm时,以pH为7.17、电压为1.8 V、体积流量为10 mL/min时处理,单级脱盐率达到15.86%,经过3级处理后脱盐率达到了46.02%。

ELECTRIC ADSORPTION TREATMENT STUDY ON REFINERY REVERSE OSMOSIS CONDENSED WATER DESALINATION

The thesis adopted electric adsorption processing to treat the reverse osmosis condensed water,first,studying simulation solution of NaCl desalination effects on some factors such as different concentrations,voltage,flow,initial pH,and obtain the best parameters by experiment condition,then by dealing with reverse osmosis condensed water to analysis desalination effect with single stage and several stages respectively.The results showed that when the initial conductivity of the simulation solution of NaCl desalination in was 2 mS/cm,pH was 7.56,the voltage was 1.8 V,the velocity was 10 mL/min,the treatment effect achieved the best,the desalination rate reached 17.18%.When the initial conductivity of condensed water was 2 mS/cm,the pH was 7.17,the voltage was 1.8 V,the velocity was 10 mL/min,the single stage desalination rate reached 15.86%,which reached 46.02% after through three stages.
