摘要
重金属离子排放到环境中只能改变形态或被转移、稀释、积累,对生物危害很大。为了处理含多种重金属离子的废水,本试验采用化学沉淀-铁氧体法处理主要含铅、锌、镉离子的废水。以云南弛宏锌锗股份有限公司废水为原水,在对影响处理效果的各种要素如温度、pH值、搅拌时间进行了条件试验后,得出了去除重金属离子废水静态试验的最佳条件。
Large amounts of wastewater containing heavy metal ions are discharged into the surrounding, which can't be degraded but only be changed in their forms or transported, diluted and accumulated in the human organisms, so it has serious impact on the health of living things. In order to dispose the wastewater containing many kinds of heavy metal ions, in this experiment, ferrite was adopted to deal with the wastewater containing irons, taking the wastewater of Yunnan Chihong zinc & germanium Co, Ltd as the raw materials. The result shows that the temperature, stirring rate and pH all affected the effect of treatment. A best condition for treatment of the waste water containing heavy metal treatment has been obtained by this experiment.
