摘要
Active carbon has been widely used to treat wastewater.In this paper active carbon adsorbent is used to treat methylbenzene resulting from the production of phenylacetic acid.Our experiment indicates that acidity has no effect on adsorbability.At temperature 22℃ and flow rate 1Bv/h,adsorption efficiency of methylbenzen is 94.2% and erasing rate of COD Cr reaches 94.9%.Alkaline alcohol solution is employed as an eluent to regenerate active carbon.After regeneration,adsorption efficiency of methylbenzene is 86.4% and the erasing rate of COD Cr is 87.3%.
