铁氧体法净化含重金属污水研究

Research on Treatment of Heavy Metal From Wastewater by Ferrite Process

对中和共沉淀铁氧体法去除污水中重金属离子进行了研究。在实验条件下,对含单一重金属离子模拟废水进行实验,发现重金属离子的离子半径等特性影响去除率的大小,各金属离子去除程度呈下列顺序:Cu^(2+),Co^(2+),Fe^(2+)>Mn^(2+),Zn^(2+)>Ni^(2+),Cd^(2+)。还对反应温度、投料比以及投料量等工艺条件进行了考察。

This paper investigates the heavy metal ion removel from wastewater. Under the experiment conditions, it is found that ionic radius and property of hydrolysis precipitation of heavy metal affect on the removal ratio of it. The order of removal ratios is: Cu^(2+), Co^(2+), Fe^(2+)>Mn^(2+), Zn^(2+)>Ni^(2+)、Cd^(2+). Moreover, the reaction temperature, addition ratio and addition amount are also discussed.
