【摘要】 研究了用聚合氯化铝 (PAC)、聚合硫酸铁 (PFS)和聚合硫酸铁铝 (PAFS)处理受污染的低浊度和高浊度原水净化效果。实验室和水厂试验均表明采用 PAF S处理受污染原水的效果明显好于采用单一的 PA C或 PF S的情况 ;适当提高 p H值对净化有利。文章还对 PAC、PFS和 PA FS的净水作用机理作了讨论。更多还原

【Abstract】 This paper investigates the purification efficiency of both low and high turbidities polluted crude water with polyaluminum chloride (PAC), polyferric sulfate (PFS) and polyaluminum ferric sulfate (PAFS) . Both laboratory and water plant experiments show that the PAFS has a superior efficiency than PAC or PFS alone in treating polluted water,and the purification efficiency was enhanced when the pH value was appropriately raised. The purification mechanisms of PAC, PFS, and PAFS coagulants are also discussed.更多还原
