摘　　要：研究了贝壳粉加入量、溶液pH和搅拌时间对重金属离子的去除效果的影响,并通过正交试验,得出最佳条件:贝壳粉加入量为20g/L、溶液pH值为10.5、搅拌时间为2h,对Cd2+、Cu2+、Mn2+、Zn2+四种重金属离子均有较好的吸附效果.The influence of sorbets dosage, pH, and stirring time on the removal rate of heavy metal wastewater by using shell-powder is studied, and the best level condition and technical prerequisite are de- termined by orthogonal experiment. The results show that the best technical conditions are as following： Dosage of 20g/L, pH=10.5, and the stirring time is 2h, which has a good effect on the absorption of heavy metal shell-powder of Cd2＋ .Cu2＋ ,Mn2＋ and Zn2＋.
