改性粉煤灰复配阳离子聚丙烯酰胺处理焦化废水的研究

Treatment of Coking Wastewater with Modified Fly Ash Combined with Cationic Polyacrylamide

利用改性粉煤灰复配阳离子聚丙烯酰胺处理焦化废水,研究了配比、搅拌时间、投加量和p H值对CODcr去除率的影响。结果表明:阳离子聚丙烯酰胺与改性粉煤灰最佳配比为100 mg/g,最佳投加量为25 g/L,最佳搅拌时间为60 min,最佳p H值为9,在最佳条件下,CODcr去除率达60.5%。

The modified fly ash combined with cationic polyacrylamide was used for the treatment of coking wastewater,the influences of ratio,dosage,stirring time and p H value on the removal rate of CODcrwas studied. The results showed that the optimal ratio of cationic polyacrylamide combined with modified fly ash was 100 mg / g,the optima dosage was 25 g / L,the optimal stirring time was 60 min,the optimal p H value was 9,under the optimal conditions,the removal rate of CODcrreached 60. 5% 。
