Experimental study on enhancing phosphorus removal by polyaluminum chloride
聚合氯化铝絮凝剂深度除磷实验研究

Phosphorus removal from synthetic and raw wastewater by polyaluminum chloride (PAC) though coagulation experiment was studied. The variation of phosphorus removal efficiency with the additions such as polydimethydiallylammonium chloride (PDADMAC) and red mud was discussed. The experimental results showed that, for synthetic wastewater the phosphorus removal rate was 94.6%, and for raw wastewater from the Small Moon River, the 96.6% of total phosphorus and 93.8% turbidity were removed. The results also showed that red mud enhanced the efficiency of phosphorus removal, but the impact of PDADMAC on that was less.
