| 摘 要： | 对聚合氯化铝(PAC)投加赤泥前后的除磷效果及絮体进行了研究.结果表明,赤泥对PO3-4有吸附作用;投加一定量赤泥,提高了实验室模拟废水和实际污水中磷的去除率;与单用PAC相比,赤泥的加入增强了絮体的持磷性,增加了絮体的密实度,缩小了底泥的体积,强化了PAC的除磷性能. |
| 关 键 词： | 聚合氯化铝 赤泥 混凝 磷 |

| Abstract: | Red mud(RM)was used to enhance the coagulation efficiency of polyaluminum chloride(PAC)for removal of phosphate. Phosphate removal efficiencies of PAC with and without RM were investigated and the flocs were studied. The results show that RM can adsorb PO3-4. The efficiencies of phosphate removal from synthetic and raw wastewater by PAC with RM added were increased. RM increased the adsorption ability and density of flocs and thus reduced the final volume of sludge and enhanced phosphate removal capability. |
| Keywords: | polyaluminum chloride red mud coagulation phosphate |
