| 摘要: |
| 利用选择性复合树脂处理含砷废水，使出水水质达到国家《地表水环境质量标准》（GB 38382002），同时从选择性复合树脂和阳离子柱上交换下来的离子可以生成H2O和中性盐类，无二次污染.研究采用201×7苯乙烯系强碱凝胶型树脂（Ⅰ）和D301大孔弱碱阴离子交换树脂（Ⅱ）作为比选树脂，通过小试试验选择具有较高交换容量的201×7苯乙烯系强碱凝胶型树脂用于放大规模的现场中试.实验所用选择性复合树脂制作成本及整个中试系统价格低廉，适合大规模工厂应用. |

| Abstract: |
| The selective composite resins were used to treat spring water containing arsenic, and the arsenic concentration in the effluent reached the Environmental Quality Standards for Surface Water(GB 3838-2002). Ions exchanged from the selective composite resin and cation exchange column have yielded H2O and neutral salt, and this method has no secondary pollution. 201×7 gel type styrene of strong akali resin (Ⅰ) and D301 macroporous have weakened the akali anionic exchange resin (Ⅱ), when compared to choose the suitable resin for arsenic removal in this study. The 201×7 resins with higher exchange capability and lower cost were applied to the pilot scale experiments on site and they were suitable to large-scale applications. |
