| 摘 要： | 分别以稀土盐、氯化稀土矿制备了稀土絮凝剂，并探讨其用量对印钞废水絮凝效果的影响；以聚硅硫酸铝铁（PAFS）与氯化稀土矿为原料，将其按一定比例进行复配制备了稀土一无机复合絮凝剂（PAFSRE），并探讨复配比例对印钞废水絮凝效果的影响。结果表明：稀土对印钞废水絮凝效果显著，COD去除率和色度去除率均大于96％；复配比例对印钞废水絮凝效果并没有明显的影响，但稀土与无机絮凝剂复配使用可在一定程度上降低废水处理成本。

| Abstract: | The rare-earth flocculants were made from rare-earth salt and rare-earth ore,and the influence of rare-earth flocculants on coagulation effects was investigated.Mean while,the coagulation effects of blending ratio from rare-earth ore to PAFS were studied.The results showed that the effects of banknote printing wastewater treated by rare-earth coagulants were quite well,COD and color removal efficiency were more 96%;the effects of coagulation were not obviously influenced by the blending ratio from rare-eart... |
