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 3838 2002),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. 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 HE O 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.
