摘　　要：采用新型絮凝剂APAC处理含Cr（Ⅵ）的模拟废水，考察了各因素对Cr（Ⅵ）及浊度去除效果的影响。结果表明：该絮凝剂对Cr（Ⅵ）有很好的去除能力，对Cr（Ⅵ）的去除率最高可达92．65％；废水的pH越高，对Cr（Ⅵ）的去除率越大；APAC中的凹凸棒组分对Cr（Ⅵ）的去除起主要作用；当APAC的盐基度为80％、投量为32mg／L、废水的pH值为7—12时，对Cr（Ⅵ）和浊度的去除效果较佳。APAC絮凝剂对Cr（Ⅵ）的良好去除效果为含铬废水的处理提供了一条新思路。A new flocculant APAC was used to treat the simulated wastewater which contains Cr（ VI ）, and the effect of different factors on removal of Cr（ VI ） and turbidity was investigated. The ex- perimental results show that APAC has strong removal capability of Cr（ VI ）, and the highest removal rate of Cr（ VI ） is 92.65%. The higher the pH value is, the higher the removal rate of Cr（ VI ） is. The attapulgite in APAC plays the main role in the removal of Cr（ VI ）. The removal efficiencies of Cr（ VI ） and turbidity are best when the dosage is 32 mg/L, the pH value is 7 to 12, and the basicity is 80%. It is concluded that APAC can be applied to Cr（ VI ） -containing wastewater treatment.
