Study on treatment for high concentration phenol shipping waster water by microwave-activated carbon

Activated carbon adsorption and microwave regeneration were investigated and evaluated for removing the high concentration phenol from ship washing wastewater in this paper.The results show that activated carbon adsorption is effective to remove the high concentration phenol and microwave regeneration can not only recover the activated carbon capacity but improve it.The adsorption capacity is increased from 196.4 mg/g to 271.1 mg/g,surface area is increased from 746.1 m2/g to 888.4 m2/g,and the cumulative pore volume is increased from 0.37 cm2/g to 0.42 cm2/g respectively by microwave regeneration.In addition,the number of carboxyl groups is significantly reduced after regeneration and makes the phenol more easy diffuse to the micro-porous by prevented the formation of water clusters effectively.
