摘　　要：为降低漂白废水化学需氧量,采用微波辐射活性炭处理含氯漂白废水。实验可以得到:25mL废水在活性炭用量1.0g,微波辐射时间为8min,功率为800W时的处理效果最好,由初始CODCr1176mg/L化学需氧量(Chemical oxygen demand,COD)下降到50mg·L-1,CODCr去除率达95%以上。有效地降低了漂白废水COD。In order to cut down the chemical oxygen demand of Chlorine-Bleaching Effluent the activated carbon was used to treat the west water under microwave radiation. With activated carbon mass fraction 1.0g, microwave radiation time 8min, microwave power 800W, the CODcr decrease from 1176mg/L to 50mg·L^-1, the removal rate of CODcris above 95%. The results show that the chemical oxygen demand of Chlorine-Bleaching Effluent can be reduced effectively and the related mechanism has been discussed.
