电吸附设备工作过程的研究

Study on performance of electrosorption equipment

研究了电压、流量及重碳酸盐碱度对电吸附设备除盐的影响,同时对高碱度水的酸化吹脱作为预处理进行了研究。实验结果表明,电吸附设备的最佳工作电压为1.4 V,最佳工作流量为1.5 m3/h。在进水碱度为170～500 mg/L时,HCO3-的脱附率为64%～83%。研究还发现,酸化吹脱是高碱度水的有效预处理方法,避免了HCO3-在电极内的积累。

The influences of voltage, flow rate and bicarbonate alkalinity on electrosorption equipment were studied. Also, the effect of acidification-stripping as pretreatment for high alkalinity water was investigated. The results show that the optimum voltage of electro-sorb equipment is 1.4 V, optimum flow rate is 1.5 m^3/h. For specific eleetrosorption equipment at alkalinity in a range of 170 - 500 mg/L, the desorption rate of HCO/ is 64% - 83%. The study indicates that using acidification-stripping as pretreatment may avoid the accumulation of HCO3 inside the electrode.
