| Abstract: | Inorganic high-molecular flocculant polysilic aluminium sulfate was made of sodium silicate, sulfuric acid and aluminium sulfate. Its application performances to treat dyeing and printing wastewater of an enterprise in Guangdong were studied. The results show that polysilic aluminium sulfate in COD removal efficiency and efficiency of decolourization is superior to ferrous sulfate. The COD removal efficiency was 31.8% and the efficiency of decolourization was over 86%, so the pressure of follow-up biochemistry system was lightened. |
