壳聚糖及其衍生物处理有机染料废水的研究

Treatment of Organic Dye Wastewater With Chitosan and Its Derivatives

利用壳聚糖与无机絮凝剂氢氧化镁进行了复合,并以亚甲基蓝和艳兰作为模拟废水来进行脱色试验研究,结果表明氢氧化镁-壳聚糖具有良好的脱色效果,利用壳聚糖作为复配剂制备的复合絮凝剂减少了镁盐的使用量,降低了废水处理的成本,而且避免了二次污染,为氢氧化镁-壳聚糖在废水处理中应用提供了依据。

Taking methylene blue and brilliant blue as simulated wastewater,decolorizing test was carried out by combined effect of chitosan and inorganic composite magnesium hydroxide.The results show that magnesium hydroxide-chitosan has a good decolorizing effect,use of chitosan reduces magnesium hydroxide dosage,which can reduce the cost of wastewater treatment and avoid secondary pollution.
