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。
In this paper , the stair FA , the secondary FA and the modified character FA with HC1 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 HC1 acid （pH was 11.17. FA dosage was 20g./L）, COD reduced to 252 mg/L, colority reduced to 90 times.
