摘要
以亚甲基蓝为污染物污染活性炭,利用微波辐照的方法对失效的活性炭进行再生。探讨了污泥活性炭的再生性能与辅助溶液的浓度、pH、微波功率、辐照时间、活性炭的用量等因素的关系。结果表明,微波法再生活性炭的最佳条件为:微波功率650 W,辐照时间120 s,辐照活性炭质量3 g。此时,其性能恢复率接近100%,甚至超过100%。
Methylene blue was employed as a pollutant to contaminate activated carbon filters and then microwave irradiation was used for regeneration of the activated carbon.The relationship between regeneration performance for saturated activated carbon and concentration of assisted solvent,pH,microwave power,time of microwave radiation,AC quantity,and other factors were discussed.The results showed that the optimized conditions of regeneration were as follows：the microwave power is 650 W for 120 s and the quantity of AC is 3 g,activated carbon regeneration capability under the optimum condition is closed to 100%,even more than 100%.
