摘要
利用改性粉煤灰负载壳聚糖处理焦化废水,研究了配比、投加量、搅拌时间和p H值对CODcr去除率的影响。结果表明:壳聚糖与改性粉煤灰最佳配比为0.1,最佳搅拌时间为25min,最佳投加量为14g/L,最佳p H值为7-8,在最佳条件下,CODcr去除率达73.6%。
The modified fly ash coated of ratio, stirring time, dosage and pH by chitosan is used for the treatment of value on the removal rate of CODcr are coking wastewater, and the influences studied. The results show that the op- timal ratio is 0.1, the optimal stirring time is 25 min, and the optimal dosage 14g/L, the optimal pH value 7 -8. Under the optimal conditions, the removal rate of CODcr reaches 73.6%.
