摘　　要：采用高分子絮凝剂聚二甲基二烯丙基氯化铵对累托石进行改性,通过正交方法研究改性累托石吸附处理含氰废水。结果表明:改性累托石用量为3.5g/L,废水pH值为4.5,吸附时间75min,氰的去除率可达98.9%。改性累托石对氰的吸附符合Langmuir模型。该工艺简单,以废治废,成本低廉,具有良好的应用前景。The rectorite is modified by the macromolecular flocculant Poly-dimethyl-diallyl-ammonium chloride. The simulation experiment on the treatment for wastewater containing cyanide with modified rectorite absorption is conducted by the orthogonal method. The results show that the removal rate of cadmium can be 98. 9% with the dosage of modified rectorite is 3. 5 g/L,pH is 4. 5 and the contacting time is 75 min. The absorption accords with Langmuir absorption isotherms. The technique is simple,the wastewater is harnessed by other waste,and the cost is lower. Therefore,it will have better applied prospect.
