| 摘 要： | 比较了无机混凝剂氯化铁、氯化铝和硫酸铝对染色废水的脱色效果，实验结果表明：氯化剂的絮凝脱色效果最佳，其适宜ｐＨ在２．５￣４．５之间，当加入适量的膨润土，则能拓宽ｐＨ适用范围，稳定脱色效果。

| Abstract: | The comparison among three inorganic coagulants (FeCl3, AlCl3, Al3 (SO4)3) to decolour dyes wastewater showed that ferric chloride is the best one among them. The optimum adjusted pH range was 2. 5~4.5,removal of color up to 96 %. Bentonite can adjust wastewater pH and stable decolour rate. |
