【摘要】 以COD去除率作性能参数,考察了PAC、PAFC、PFS三种絮凝剂及其复合磁絮凝剂在高、低两种浓度餐饮废水中的絮凝效果,并对PFS+PAM+磁粉组合的复合磁絮凝剂在高浓度餐饮废水中絮凝效果作了研究。结果表明,与普通絮凝剂相比,在高浓度餐饮废水中,PFS+PAM+磁粉组合的复合磁絮凝剂能进一步提高絮凝效果,缩短废水分离时间,并使污泥体积减少一半。磁场能大大缩短废水分离时间。更多还原

【Abstract】 COD removal rate as a parameter,PAC,PAFC,PFS flocculants and their complex magnetic flocculants used in two defferent concentration restaurant wastewater are studied respectively.PFS + PAM + magnetic flocculants used in the restaurant wastewater with high concentration are systematically studied,too.The result indicates that comparing with ordinary flocculants,PFS + PAM + magnetic flocculants have better flocculating effectiveness,and shorten sedimentation time further,and reduce the sludge volume.Magnetic field can shorten the period of sedimentation greatly.更多还原
