Bipolar three-dimensional electrode method to deal with nitrobenzene wastewater

With iron plate as anode,graphite as cathode and activated carbon as medium,the processing efficiency to nitrobenzene wastewater are studied by the bipolar three-dimensional electrode method considering some factors.The optimal operation conditions are: cell voltage 20 V,reaction time 60 min,(GAC) adding quantity 20 g/L,electrode space 4 cm about,wastewater pH value 6.0～7.0,adding quantity of electrolyte 0.8 g about.The disposal efficiency is over 80% and COD removal rate over 50%.
