【摘要】 研究了聚合氯化铝(PAC)、聚合氯化铁(PFC)以及聚丙烯酰胺(PAM)3种高分子絮凝剂单独以及配合使用处理长江原水时pH值、温度、絮凝剂用量等因素对浊度去除效果的影响。结果表明,PAC、PFC与PAM配合使用除浊效果要优于单独使用的效果;PAC、PFC与PAM投加浓度比为30∶1时,除浊效果最好,且浊度去除率在较宽的温度范围(10~40℃)和pH值范围(5.0~8.0)内均可达到90%以上。更多还原

【Abstract】 The flocculation effect of poly-aluminum chloride(PAC),poly ferric chloride(PFC) and cationic poly-acrylamide(PAM),which wasused alone or cooperated with each other,on the water treatment of the Yangtze River is studied.The effect factors included the pH,temperature and the dosage of flocculent.According to the experiment,the effect of PAC or PFC cooperating with PAM was better than that of the single one.The optimum ratio of PAC or PFC to PAM was 30:1.At 10℃～40℃ and pH=5.0～8.0,the removal ratio of turbidity was all above 90%.更多还原
