| Abstract: | A process for preparing polysilicate aluminum ferrite coagulant from coal gangue and blast furnace sludge under normal pressure has been studied,determining the reasonable production craft and operating conditions.The coagulant was tested in real wastewater treatment and compared with polyferric sulfate,proving that the removal rates of effluent COD and color were increased all by 30%,and that of SS by about 10%.The reaction mechanism of the coagulant in wastewater treatment was also explored. |
