| 摘 要： | 应用磁种凝聚 磁分离技术处理Ni2 + 电镀废水。首先进行了磁种凝聚的试验 ,研究了pH、磁种、聚丙烯酰胺对Ni(OH) 2 沉淀物与磁种凝聚成“磁性矾花”过程的影响。其次进行了从废水中脱除磁性矾花的磁分离试验 ,考查了磁分离器的磁场强度对磁分离过程的影响。试验结果表明 ,经这种方法处理后 ,废水中Ni2 + 的去除率达到 99%以上 ,出水中Ni2 + 浓度为 0 4 2mg L ,而且Ni2 + 可以回收 ,磁种经酸泡后可以循环再用

| Abstract: | The technique of magnetic particle coagulation magnetic separation was used to treat Ni 2+ bearing electroplating wastewater.The test of magnetic particle coagulation was conducted to study the effects of pH value,magnetic particle and polyacrylamide on the formation of alumen ustum by Ni(OH) 2 deposit and magnetic particles; and then the magnetic separation test of removing the alumen ustum from the wastewater was also conducted.The test results showed that the removal rate of Ni 2+ in the wastewater was up to over 99% with a concentration of Ni 2+ in the effluent being 0.42 mg/L. |
