聚合氯化铝铁与壳聚糖复合絮凝剂的制备及其对印染废水的处理

摘要

Orthogonal experiment method of dyeing wastewater coagulation optimal experimental conditions were studied. By ferric chloride (PAFC) and chitsoan(CTS) simulated dyeing wastewater treatment research confirms showed that:the pH value of 7, PAFC and CTS dosing ratio is 1∶1, the temperature is 55℃, stirring time was 15 min, the simulated dyeing wastewater treatment to get satisfactory results, COD removal rate was 70.63%, the treated water absorbance of 0.3017.%利用正交实验的方法，研究了聚合氯化铝铁(PAFC)和壳聚糖(CTS)对模拟印染废水的处理效果，结果表明，在溶液pH值为7，PAFC与CTS投加量比值为1∶1，温度为55℃，搅拌时间为15min时，对模拟印染废水处理得到较为满意的效果，COD去除率为70.63%，经处理后水的吸光度为0.3017。
