摘要
对粉煤灰复配阳离子聚丙烯酰胺的除浊影响因素进行了研究。结果表明:当粉煤灰复配阳离子聚丙烯酰胺配比为50 mg/g,搅拌时间为80 min,投加量为1.4 g/L时除浊效果最好;随p H值增大,除浊率先降低后升高,p H值为9.6时,除浊率最低,在最佳条件下,p H值为5.57时,除浊率高达84.53%。
The influence factors of turbidity removal by fly ash combined with cationic polyaerylamide were studied. 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.
