摘　　要：依据竹炭较强的吸附能力和阳离子型聚丙烯酰胺(PAM)优良的絮凝效果将二者进行优化组合,得到组合型水处理剂竹炭-CPAM,并对其处理城市生活污水的絮凝性能进行了研究。结果表明,竹炭具有丰富的孔隙和比表面积,因此有强的吸附能力;对于城市污水,组合型水处理剂的效果好于单一絮凝剂,其对城市污水COD的去除率、透光率和沉降速率分别达到83.7%、82.21%和300mm/min左右,各项指标比CPAM单独处理时提高了将近2倍。A novel combined bamboo charcoal and cationic polyacrylamide(CPAM) flocculant basing on adsorption - coagulation was designed and evaluated for the treatment of municipal sewage.The results showed;Bamboo charcoal have strong absorption capacity due to high porosity and BET surface area;The combination treatment efficiency for municipal sewage was higher than individual CPAM.Under the optimal condition the COD reduction,transmittance and settling rate reached 83.7%,82.21%and about 300mm/ min respectively,which were enhanced about 2 folds than individual CPAM.
