Coagulation Performance of Organic Modified Poly-Polyacrylamide-Al-Zn-Fe (PPAZF) Coagulant

Abstract:

An organic modified poly-polyacrylamide-Al-Zn-Fe (PPAZF) coagulant was prepared by adding polyacrylamide (PAM) as additives in poly-Al-Zn-Fe (PAZF). The coagulation performance of PPAZF was investigated compared to that of PAZF and polyaluminium chloride (PAC) in treating domestic sewage and pharmaceutical wastewater. The results showed that PPAZF not only had better removal of turbidity and chemical oxygen demand (COD_Cr) than PZAF and PAC at the optimal dosages of 148 mg·L^-1, but also produced large and dense flocs. Compared to PAZF and PAC, the removal of COD_Cr by PPAZF was greatly improved at lower dosage. In addition, experimental results indicated the main mechanism of PPAZF is a comprehensive coagulation effect and chemical reaction.
