| 摘 要： | 研究了聚合氯化铝-壳聚糖(PAC-CTS)絮凝剂的絮凝特性,进行了聚合氯化铝-壳聚糖复合絮凝剂和单独聚合氯化铝对水中溶解态腐殖酸的去除实验。结果表明:复合絮凝剂在投加量为80 mg/L时即可达到与单独聚合氯化铝投加量为150 mg/L时的去除效果,同时前者适应的pH值范围更宽;与投加量和pH值相比,水样浊度和絮凝搅拌速度是影响絮凝效果的次要因素;另外红外光谱分析发现复合絮凝剂中壳聚糖与聚合氯化铝之间存在相互作用。

| Abstract: | The flocculation characteristics of poly aluminum chloride-chitosan (PAC-CTS) composite flocculant was studied and the removal of dissolved humic acid in water was investigated with composite flocculant and PAC only.The results showed that the dosage of the composite flocculant and PAC were 80,150 mg/L,respectively,to achieve the same removal rate.And the composite flocculant could adapt to a wider range of pH.Turbidity and flocculation stirring speed were the secondary factors affecting the flocculation effect when compared with the dosage and pH value.And the fourier tansform infrared(FT-IR) analysis of the flocculant showed that there was an interaction between PAC and CTS. |
