摘要
采用粉煤灰作原料制备聚硅酸铝 (PSAA)混凝剂 ,并通过化学沉淀、络合、凝聚和絮凝等反应将其用来处理热电厂含氟废水。结果表明 ,本法处理成本低廉、过程简单、实用、排渣少 ,实现了资源的充分利用。
Polysilicate aluminum (PSAA) was prepared from fly ash,and used as defluorider and coagulant in the treatment of waste water containing fluoride from power plant by chemical deposition,camplexation,agglomeration and flucculation.The results show that the treatment technology is simple and economical and practical for the purpose of full utilization of waste resources in power plants.
