【摘要】：利用自制的膜电极进行膜电容去离子(MCDI)实验,并对离子交换膜的性能指标进行了表征。探讨了各因素对膜电容去离子效果的影响,确定了最佳参数。研究结果表明,对于安装1对电极、电极面积共400 cm2的实验装置,电吸附的最佳操作条件:施加电压1.2 V、进水流速17.0 m L/min、Zn2+45 mg/L,最佳条件下对Zn2+的去除率为97.64%。在对矿山开采废水处理时,MCDI的TDS吸附量为26.61 mg/g,高于电容去离子(CDI)的18.75 mg/g。
[Abstract]:The membrane capacitance deionization (MCDI) experiment was carried out with the self-made membrane electrode, and the performance of the ion exchange membrane was characterized. The influence of various factors on the deionization effect of membrane capacitance was discussed, and the optimum parameters were determined. The results show that the optimal operating conditions for electrosorption are as follows: voltage 1.2 V, influent flow rate 17.0 mL / min, Zn 245 mg / L, and the optimal removal rate of Zn 2 is 97.64 g / L for an experimental device with an electrode area of 400 cm2. In the treatment of mining wastewater, the TDs adsorption capacity of MCDI is 26.61 mg / g, which is higher than that of capacitive deionization (CDI) 18.75 mg / g.
