摘　　要：采用氨基膦酸螯合树脂C-900去除丙烯酸丁酯废水中的二价阳离子,考察了吸附温度和废水流量对树脂动态吸附性能的影响,并用Thomas模型进行动态吸附数据的拟合分析。实验结果表明,在吸附温度为35℃、废水流量为15 SV的条件下,处理后出水中3种二价阳离子总质量浓度为1.0 mg/L时的穿透体积为240 BV,达到穿透体积时树脂对Ca2+,Mg2+,Cu2+的去除率分别为100%,99.2%,99.8%。The amino phosphoric acid chelating resin C-900 was used to remove bivalent cations from butyl acrylate wastewater.The effects of adsorption temperature and wastewater flow rate on the dynamic adsorption capability of the resin were investigated.The dynamic adsorption data were fitted and analyzed with Thomas model.Under the conditions of adsorption temperature 35℃ and wastewater flow rate 15 SV,and when the total mass concentration of the 3 bivalent cations in the effluent is 1.0 mg/L,the breakthrough volume is 240 BV and the removal rate of Ca^2＋,Mg^2＋,Cu^2＋are 100%,99.2% and 99.8% respectively.
