Inorganic flocculant CF-PAC、Al-pillared rectorite act as sorption mostly ; Meanwhile organic flocculant chitosan acts as the adsorption bridge mainly. Chitosan coagulates fine flocci together into lager、impact floccules and greatly strengthens the polymerization degree and coacervation force. The sedimentation rate and adsorption efficiency rise greatly. So the flocculation efficiency of this composite flocculant is superior to the single one.

无机絮凝剂CF-PAC、铝交联累托石主要起吸附作用，而壳聚糖主要起吸附桥连作用，将细小的絮粒凝结在一起形成更大更致密的絮体，并使聚合度和凝聚力大大增强，从而使其沉降速度和吸附效率大大提高，起到优于单一絮凝剂的絮凝效果。
