摘要
介绍了高浓度含氟废水的处理方法,采用氯化钙-聚丙烯酰胺絮凝沉淀工艺进行处理,并控制一定的操作条件,出水中的氟离子含量小于10 mg/L,完全满足国家排放标准,且系统运行稳定,工艺简便。
The treatment for the high-concentration fluoride wastewater was carried out. The process was precipitated with calcium chlorid and polyacrylamid,and controlled some operating conditions. The concentration of fluoride in outflow reduced below 10 mg/L,which comes up to the national standard. And the system was characterized by stable operation and simple process.
