| 摘 要： | 以蒙脱石、凹凸棒石、次氯酸钙和PAC、PAM为基本材料，对焦化废水二级生化出水进行深度处理。实验结果表明：蒙脱石与凹凸棒石以4：1的比例配合使用，可明显提高焦化废水中COD和色度去除率；采用次氯酸钙作为氧化剂，可进一步提高焦化废水的脱色率和COD去除率，处理间差异达到极显著和显著水平；去除COD的最优实验条件为：粘土矿物（蒙脱石：和凹凸棒石=4：1）添加量4．0g／L、氧化剂（次氯酸钙）添加量1．0g／L、絮凝剂（聚合氯化铝：聚丙烯酰胺=15／1）添加量0．15g／L，处理后色度去除率达到97．0％，COD去除率达到69．1％；脱色的最优实验条件为：粘土矿物添加量4．0g／L、氧化剂添加量1．0g／L、絮凝剂添加量0．2g／L，处理后色度去除率达到98．5％，COD去除率达到66．4％。
