| Abstract: | A new preparation method of high efficient coagulant of polysilicate aluminum ferrite (PSAF) was studied, the preparation method utilizes sulfuric acid of low concentration to leach red mud in a alumina plant in oxygen and at normal pressure, and the reasonable production craft and operation condition were determined. The coagulant PSAF has been applied to treat industrial wastewater, its treatment effect is compared with that of PFS, the removal rates of CODCr and color are increased about 20% and 28% respectively, the removal rate of SS is increased about 10 % . The reaction mechanism of treating wastewater on the coagulant has been studied simultaneously. |
