聚氯化铝/聚丙烯酰胺复合絮凝剂处理染料废水的研究

Study on Treatment for Sulphur Black Dyes Wastewater by Polyaluminium Chloride-Ferroferric Oxide-Polyacrylamide Composite Flocculant

研究了聚氯化铝-Fe_3O_4-聚丙烯酰胺复合絮凝剂对硫化黑染料废水的去除效果。研究结果表明,该复合絮凝剂对硫化黑染料废水具有较好的絮凝效果,在絮凝剂投加量为20 mg/L、废水pH值为8.0的条件下,该复合絮凝剂对硫化黑染料废水的浊度、色度、COD的去除率分别为95.59%,97.67%,85.55%。

The removal efficiency of sulphur black dyes wastewater was investigated by using polyaluminium chloride -ferroferric oxide- polyacrylamide composite flocculant as flocculant. Results indicated that this composite flocculant had a good flocculation effect for sulphur black dyes wastewater in the condition of flocculant dosage 20 mg/L and sulphur black dyes wastewater pH value 8.0 and COD, turbidity and chromaticity removal rate of sulphur black dyes waste water was 95.59%, 97.67% and 85.55% respectively.
