The RE of TP, COD and turbidity except NH4+-N in the aeration process by adding AS and PAM for enhanced chemical phosphorus removal increased by 7.3~59.2%, 5.0~20.3% and 10.9~34.7%, respectively. Given enough dissolved oxygen, the nitrification was not affected by adding AS and PAM in the dosage range of the study. The RE of TP, COD and turbidity by postpose coagulation were better than by simultaneous coagulation, however, coagulation and sedimentation equipments were needed in postpose coagulation process. Therefore simultaneous coagulation was more suitable for transformation of AB process for chemically enhanced phosphorus removal.

曝气过程中投加AS和PAM复配化学强化除磷，总磷、COD、浊度去除率分别提高了7.3～59.2%、5.0～20.3%、10.9～34.7%，但不能提高氨氮的去除率；在溶解氧足够时，本研究投加量范围的AS和PAM的加入对硝化作用无影响；后置混凝对TP、COD、浊度的去除效果优于同步混凝，但需增加混凝沉淀设备，因此同步混凝更适合于于AB工艺的化学强化除磷改造。
