The results showed that the effect of turbidity removal was the best when the ratio of fly ash combined with cationic polyacrylamide was 50 mg/g, the stirring time was 80 min, the dosage was 1.4 g/L; with the increase of pH value, the removal rate of turbidity decreased at first and increased afterward, when the pH value was 9.6, the removal rate of turbidity was the lowest; under the optimal conditions, the removal rate of turbidity was as high as 84.53% when the pH value was 5.57.
