| 摘 要： | 通过实验室模拟混沉降法除氟过程，研究了铝型材工业废水除氟的达宜工艺条件。在实验条件下，氟与氢氧化钙、聚铝、FW络合助剂形成多元络合物复合盐，然后用聚丙烯酰胺絮凝，废水中氟浓度可降至4mg/L。经过两厂的工业废水现场试验，初步结果表明，排放废水含氟量达到国家标准。

| Abstract: | The
moderate technological conditions for fluoride re moval in aluminum industry by
coagulation and precipitation are studied. Under t he experimental conditions fluoride
forms a multicomponent complex with calcium h ydroxide,polymeric aluminum.FW complexing
agent and coagulates with polyacrylami de. The fluoride concentration of wastewater can be
reduced to 4 mg/L. The resul ts of two aluminum industry tests show that the amount of
fluoride in wastewater meets the drainage standard. |
