| 摘 要： | 利用一级、二级粉煤灰(商品级干灰)和盐酸改性粉煤灰对印染废水进行了去除COD和色度的处理研究。对于COD为970mg/L、色度为167倍的印染废水,在pH为2、投灰量为10g/L时,经一级、二级粉煤灰处理后,COD和色度分别降低到522 mg/L5、33 mg/L和33倍、35倍;在未调废水pH,投灰量为20 g/L,经盐酸改性一级粉煤灰处理,COD和色度分别降低到252 mg/L和90倍。

| Abstract: | In this paper,the stair FA,the secondary FA and the modified character FA with HCl acid was used to remove COD and colority of printing & dyeing wastewater.Water quality of printing & dyeing wastewater was as follows: COD was 970mg/L,colority was 167 times.After the wastewater was treated with the stair FA,the secondary FA(pH was 2,FA dosage was 10g/L),COD and colority reduced to 522 mg/L,533 mg/L and 33 times,35 times respectively.After the wastewater was treated with the modified character stair FA with HCl acid(pH was 11.17.FA dosage was 20g/L),COD reduced to 252 mg/L,colority reduced to 90 times. |
