A new method of the removal of p-aminophenol wastewater is studied, while the nitrobenzene produced p-aminophenol by catalytic hydrogenation, and the techniques of removing p-aminophenol are recommended. The result shows that it can reach the requirement of China wastewater dischange standard. The detail of this method is adding farmalin to the wastewater by the mol ratio of 2(formalin/p aminophenol)25 ℃, pH=7. Filter the mixture out after 24 h. Then the filtrate is oxidized by KMnO4 and absorbed by active carbon. Thus the result shows that the technique is easy and reliable.
Key words： wastewater treatment; p-aminophenol; active carbon
