| 摘 要： | 以粉煤灰为原料,在一定条件下进行活化,再添加适量的固化剂、凝结剂和无机聚合剂并混匀,通过加热、蒸汽养护等工序,制成新型轻质多微孔粉煤灰陶粒,并以此填充于曝气生物滤池中,用于印染废水的处理。结果表明,该种填料由于会释放出Al3+、Fe3+形成无机絮体,与其它粉煤灰陶粒相比,在系统启动过程中和启动后,具有对各污染物都有更好的去除能力,在进水COD、BOD5、色度和SS平均浓度为954.39 mg/L、255 mg/L、551.4倍和2 297.2 mg/L时,水解酸化-BAF系统的平均去除率分别可达90.8%、89.3%、88.9%和96.7%。处理后出水达到纺织染整工业废水排放标准(GB4287-92)的Ⅱ级标准。
