| 摘 要： | 针对低浓度含磷废水，用铝交联剂对膨润土进行改性，并用改性膨润土处理低浓度含磷废水。结果表明铝交联改性膨润土对低浓度含磷废水有较高的去除率；利用方差分析得到改性膨润土处理低浓度含磷废水的最优条件为改性膨润土投加量为1g／100ml。废水，搅拌时间为30min，pH值为7。

| Abstract: | Aiming at low concentration of phosphate-containing wastewater, the modified bentonite was applied to remove phosphate from wastewater in this study. The bentonite was modified by Al cross-linked method and the removal performance of low phosphate concentration by the modified bentonite was studied. The results showed that the removal efficiency of phosphate in the low concentration wastewater was high. The optimum condition for addition of modify bentonite was 1 g/100 mL wastewater,and the stir time was 30 min and the value of pH was 7. |
