| 摘 要： | 以天然植物粉Ｆ６９１为原料,通过羧甲基化、接枝共聚和曼尼期(Ｍａｎｎｉｃｈ)三步反应合成出两性天然高分子改性絮凝剂(ＣＧＡＡＣ),确定了其较佳的制备条件;ＣＧＡＡＣ对造纸抄纸白水和造纸混合污泥的絮凝脱水试验表明:１０ｍｇ·ｌ－１ＣＧＡＡＣ与４０ｍｇ·ｌ－１ＰＡＣ配合使用,ＣＯＤＣｒ去除率可达７２%,效果优于对比样ＰＨＰ;ＣＧＡＡＣ对造纸混合污泥的絮凝脱水性能优于对比样ＰＨＰ和ＰＡＭ－Ｃ．

| Abstract: | In this paper , the natural wood powder F691 was modified by carboxmethyl reaction, graftingreasction and Mannich reaction to prepare a new amphoteric polymenic flocculant (CGAAC),the optimuml conditions for the preparation of CGAAC were determined. The result of applying CGAAC to the white wastewater and the mixed sludge from a papermaking mill shows: CGAAC has goodproperties of flocculation and filtration, which is superior to that of PHP and PAM-C. |
