摘　　要：研究了天然高分子絮凝剂仙人掌的絮凝性能,标准水样用高岭土配制.分别处理较高浊度(100～200NTU)和低浊度(20～50 NTU)的标准水样,结果表明,仙人掌絮凝剂对浊度的去除率比较高,最终的出水浊度可以达到5 NTU.仙人掌絮凝剂的最佳用量与AlCl3·6H20相比仅仅高-点.可以推测,仙人掌组分中的非极性成分在絮凝过程中起了重要的作用.The flocculation performance of natural macromolecular flocculant cactu s has been studied. The standard water sample is prepared with kaolin. If the wa ter sample with higher turbidity (100-200 NTU) and that with lower turbidity (20-50 NTU) are treated separately, the effect of cactus flocculant on the tur bidity removal is comparatively higher. The turbidity of the effluent at the end is up to about 5 NTU. The optimum dose of cactus flocculant is only a bit highe r than that of AlCl3·6H2O. It can be presumed that the nonpolar component in ca ctus plays an important role in the flocculation process.
