摘要:

通过试验探讨了利用粉煤灰和赤泥制备复合絮凝剂FC的最佳工艺,并将FC与市售聚合氯化铝(PAC)和明矾做了对比,试验表明,FC复合絮凝剂的絮凝效果较好,残余铝量比明矾低。

关键词: 粉煤灰, 赤泥, 复合絮凝剂, 明矾, 残余铝

Abstract:

The process for preparation of a novel inorganic composite coagulant from coal ash and red mud has been studied. The results of flocculating effect tests in comparison with polyaluminum chloride(PAC) and alunite show that the new coagulant has better flocculation performance, and lower residual aluminum than alunite.

Key words: coal ash, red mud, composite coagulant, alunite, residual aluminum
