活性炭吸附法处理对氨基苯酚生产的废水

Treatment of p-Aminophenol Effluent with Active Carbon Adsorbent

提出了用活性炭吸附处理对氨基苯酚(PAP)废水的工艺流程,探讨了5种活性炭的吸附平衡曲线。以果壳炭为吸附剂,考察了吸附处理对氨基苯酚废水的影响因素,测定了穿透曲线、工作段高度与线速度的关系、穿透曲线与循环次数的关系。实验还证明了w=0.18的硫酸溶液脱附活性炭是可行和有效的,脱附液能作为原料液充分利用。用此法处理后的废水,对氨基苯酚含量小于0.001%,从而实现了对氨基苯酚绿色生产过程。

A novel process is proposed for treatment of p-aminophenol effluent with active carbon (adsorption.) Five adsorption equilibriums of active carbon are discussed. It has been studied to dispose (the p-aminophenol) in the waste using a peel carbon. The breakthrough curve has been measured. The (relationships) of working lining length and linear velocity, as well as breakthrough curve and cyclic load (elution) have been obtained. The experimental results show that it is available and effective to use (w_(H_2SO_4)=0.18) solvent as desorbent, and that the concentration of p-aminophenol will be less than 0.001%. The green manufacturing process for p-aminophenol is realized.
