| Abstract: | A new method for preparing high efficient coagulant of polysilicate aluminum(PSA) from coal gangue was studied and its reasonable production process and operating conditions discussed.PSA coagulant was tested in the treat-ment of industrial wastewater and compared with polyferric sulfate(PFS),it has been found that the removal ratios of COD and color were increased by approximately 20% and 25%,respectively,and the removal ratio of SS was increased by about 10%,the effect of wastewater treatment was very goo... |
