摘要

对工业废水中的六价铬离子进行了脱除。为此，制备了一种携带碱性阴离子树脂的支架。在不同的pH、温度和体积流速条件下，采用实验装置对离子交换过程进行了动力学研究。利用汤姆逊方程计算了交换溶质的速率常数(k)和最大固相浓度(q0)，放大了制革、摄影和陶瓷工业中铬(VI)工业径流的净化过程。实验优化表明，所开发的装置可将4万dm3废水中的铬(VI)从300 mg/dm3去除至5 mg/dm3。为达到10 000 dm3/天流速的最佳效果，建议使用12.03 kg阴离子树脂，将装置的pH固定在7.4，同时保持处理温度为20℃。

Removal of chromium(VI) from wastewater through ion exchange. Kinetic and scale up studies

Chromium(VI) ions were removed from industrial wastewater. In this regard, a rig was fabricated carrying alkaline anion resin. Various experiments were carried out by varying pH, temperature and volumetric flow rate of solution by employing a rig to study the kinetics of the ion exchange process. The rate constant (k) and maximum solid phase concentration of exchanged solute (q0) were calculated using the Thomson equation to scale up the purification process of industrial runoff of chromium(VI) from the tanning, photography and ceramic industry. Experimental optimization revealed that developed setup will remove chromium(VI) to a level of 5 mg/dm3 from 300 mg/dm3 in 40 000 dm3 of wastewater. To achieve the best results for the flow rate of 10 000 dm3/day, 12.03 kg of anionic resin were recommended by fixing the pH of the setup at 7.4 while maintaining the treatment temperature at 20 °C.
