| Abstract: | A new type of low-cost,high flocculation efficienct inorganic-organic compound flocculant was prepared with polysilicate aluminum ferric and chitosan.It was found that the optimal conditions of prepatation were pH between 1.4 ～ 2.0,raw material ratio as 1:1,reaction temperature at 70 ～ 80 ℃,and reaction time for 16 hours.Also,the prepared flocculant was used in paper making wastewater treatments with the ratio of PSAF-CTS as 9 mL /500 mL,and the observed removal rate for turbidity,chrominance and COD were 94.5%,92.3% and 78.7%,respectively. |
