【摘要】 通过试验探讨了聚苯乙烯滤料在直接过滤、再絮凝过滤和载粉末活性炭 (PAC)过滤中的应用。结果表明 :粒径为 1 2 5～ 2 5mm ,厚度为 10 0 0mm的聚苯乙烯滤料在投加硫酸铝及阳离子型聚合物T30 10 时 ,既可用于直接过滤 ,又可用于再絮凝过滤及载PAC过滤。更多还原

【Abstract】 The performances of polystyrene filtration media in different operations such as the direct filtration, the re flocculation filtration and the powdered activated carbon (PAC) filtration are researched experimentally. The results show that in case that cationic polymer T3010 was added, filtration layer with grain size of 1 25～2 5 mm and depth of 1 000 mm could be convenient for direct filtration, and it is also suitable for re flocculation and PAC filtrations.更多还原
