活性炭三维电极-电吸附降解炼油废水
Electrosorption degradation of oil refinery waste-water by active carbon three-dimensional electrode
摘要
Abstract
Oil refining waste-water was treated by a three-dimension electrode method filling with active carbon particles.And the factors affecting the organic matter degradation as well as the treatment efficiency of COD,NH4 +-N and heavy metals were investigated.The results were compared including the direct electrolysis,added active carbon,adjusted pH,added ac-tive carbon and air,adjusted pH and air with the addition of active carbon experimental con-ditions.It was found that,the optimal conditions for the waste-water treatment were found to be:a cell voltage of 15 V and initial pH value of 3.0,electrolysis duration of 60 min,an ac-tive carbon dosage of 3 g in 200 mL oil refining waste-water in the presence of aeration with Na2 SO4 as supporting electrolyte.In the optimal conditions,the removals of COD and NH4 +-N reached 80.7% and 82.1%,respectively.In addition,according to iodometric and colori-metric methods results,the mechanism of degradation was explored during the electrosorp-tion process.关键词
