Abstract: Macroporous resin has been used for the adsorption treatment of the industrial wastewater containing s-triazine compounds(melamine as a representative). The adsorptive removing effect of macroporous resin on the s-triazine compounds, and the effect of active chlorine on the adsorption capacity of macroporous resin are investigated. The results show that macroporous resin can effectively treat the industrial wastewater containing s-triazine compounds. The concentration of nitrogen-containing compound in the treated wastewater can be reduced by 70% or so. In addition, soda-wash and pickling methods can be used for desorption. After desorption, the change in adsorption capacity is not much. The macroporous resin can be used repeatedly. Therefore, macroporous resin is one of the excellent kinds of adsorbent for treating this kind of wastewater.

摘要： 采用大孔树脂吸附处理含均三嗪类化合物（以三聚氰酸为代表）工业废水，考察了大孔树脂对均三嗪类化合物的吸附去除效果以及活性氯对大孔树脂吸附性能的影响。结果表明，大孔树脂可有效处理含均三嗪类化合物工业废水，处理后废水中的含氮化合物浓度可降低70%左右，且能利用碱洗和酸洗的方法对其进行解吸，解吸后吸附性能变化不大，可以重复使用。大孔树脂是处理该类废水的优良吸附剂之一。
