Abstract:

The modified fly ash coated chitosan has been used for the treatment of high-turbidity water. The influences of mass ratio,stirring time,dosage and pH on turbidity removing capacity are studied. The results show that the removing rate of turbidity is the best and the removing rate of turbidity is as high as 98%,when the mass ratio of chitosan and modified fly ash is 0.1,stirring time 30 min,dosage 3 g/L,and pH 7-8.

Key words: fly ash, chitosan, high-turbidity water

摘要：

利用改性粉煤灰负载壳聚糖处理高浊水,研究了质量比、搅拌时间、投加量和pH对除浊性能的影响。结果表明,当壳聚糖与改性粉煤灰质量比为0.1、搅拌时间为30 min、投加量为3 g/L、pH为7~8时,除浊效果最佳,除浊率高达98%。
