絮凝剂PAC和PAM处理洗涤废水的应用研究

摘要

The optimum conditions of the combination of using PAC and PAM flocculants treating washing wastewater obtained from a laundry factory in NanXiong City were explored, through the CODCras the index standing for treatment effect by changing the initial pH value, the quantities of the PAC and PAM flocculants, and the precipitation time, mensurating the CODCrconcentration of the wastewater to reflect the treatment efficiency. Results suggested that the best treatment efficiency appeared when the initial pH value was 7, the quantities of the PAC was 6 mL, the precipitation time was 30 min and the quantities of the PAM was 2 mL.%以南雄市某洗涤企业综合洗涤废水为研究对象, 探讨了PAC(聚合氯化铝)和PAM(聚丙烯酰胺)共同处理该洗涤废水的最佳条件, 以CODCr为指标反映处理效果, 通过改变初始 pH值、絮凝剂 PAC及 PAM 用量、沉淀时间等因素, 测定废水CODCr浓度, 反映处理效果.结果表明: 当初始pH值为7, PAC添加量为6 mL, 沉淀时间为30 min, PAM添加量为2 mL时, 处理效果最佳.
