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 indicatesthat 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.

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。
