Abstract:

Multi-core composite polyaluminum coagulants PAFC and PAZC were prepared by adding Fe~(3+) and Zn~(2+) respectively.Assaying of residual aluminum shows that composite coagulants PAFC and PAZC have wider pH range,lower residual aluminum concentrations,fewer dosages.For archieving 85%of COD removal efficiency treated by PAZC,PAFC and PAC respectively,the dosages of coagulant are 5,10 and 20 mg/L;the residual alumimum of treated effluent are 0.04,0.09 and 0.14 mg/L;the treatment costs are 0.020,0.028 and 0.048...
