摘　　要：对含重金属离子废水的有效处置一直是人们所关注的热点问题。膨润土处理废水的方法简单、有效且成本低,重金属在脱吸附时的释放率较低,较少二次污染。本试验采用膨润土作为吸附剂,研究其对废水中锌离子的吸附规律。结果表明,膨润土对废水中的Zn2+具有较好的吸附效果。The effective treatment of wastewater polluted by heavy metal ions is a problem concerned deeply.Treating wastewater with bentonite has many merits such as easy to operate, effective, low cost and little second - pollution. So, the experiments of adsorbing Zn^2＋ from wastewater with bentonite were carried out and test results showed that satisfied adsorption effect could be gained.
