摘要:

以天然高分子植物粉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)。CGAAC对污泥脱水性能的研究结果表明:在用量为2~20mg/L的范围内,CGAAC能明显改善污泥的沉降性能和过滤性能,其脱水性能优于阳离子絮凝剂PAM-C。

Abstract:

The natural wood powder F691 is modified by carbox ymethyl reaction, grafting reaction and Mannich reaction to prepare a new ampho teric polymeric flocculant (CGAAC). The result of applying CGAAC to sludge dewatering shows: between 2~20mg/L, CGAAC can obvio usly improve the property of sedimentation and fil tration, which is superio r to that of PAM-C.

Key words: amphoteric polymeric flocculant, carbox ymethyl reaction, graf ting reaction, Mannich reaction
