摘　　要：以微波-碱协同改性的粉煤灰为吸附剂处理含镉废水,考察了不同工艺条件对镉去除率的影响。结果表明,影响镉去除率的工艺因素次序为:粉煤灰投加量>p H值>吸附时间>温度,最佳工艺条件为投加量1.5g,吸附时间1.5h,p H=7,温度20℃。采用此工艺处理含镉废水,快速、简便、成本低、效果好,达到了以废治废的目的。Cadmium-containing wastewater was treated with fly ash modified by microwave and alkali.The effect of different process conditions on the removal rate of cadmium was investigated.The results showed that the order of technological factors affecting the removal rate of cadmium was:dosage>pH>adsorption time>temperature.The optimum technological conditions were:dosage of fly ash was 1.5g,adsorption time 1.5h,pH=7,temperature was 20℃.This process was fast,simple,low cost and good effect,so as to achieve the goal of waste disposal.
