摘要
本研究以聚合氯化铝(PAC)为絮凝剂处理高浊度水源水。以超纯水配高岭土为水样,水样浊度为200NTU。考察了PAC投加量、水样p H值、搅拌速度和自由沉降时间对絮凝出水浊度的影响。结果表明,p H为强碱性,PAC浓度为30mg·L-1,搅拌速度200 r·min-1,自由沉降时间30min时,絮凝效果最佳。
In this study, polyaluminium chloride (PAC) was used as flocculant in high turbidity source water treatment. The kaolin and ultrapure water was used in preparation of water samples, the experiment water turbidity was 200NTU. The effects of PAC dosage, water pH, stirring speed and free settling time on the effect of flocculation effluent turbidity were investigated. The results showed that the flocculation efficiency was the best when the pH value was strong alkaline, the concentration of PAC was 30mg/L,the stirring speed was 200 r/min and the free settling time was 30min.
