For the degradation of nitrobenzene in industrial waste water,we studied the nitrobenzene waste water under pulse plasma using needle-to-plane electrode reactor,and analyzed the influences of voltage,solution conductivity,pH value,initial density,as well as gas import of the solution on the efficiency of nitrobenzene through a series of contrast experiments.Through the mass spectrum picture of pulse plasma discharge in bubble water,we deduced the influence of reaction on the degradation of nitrobenzene in water.The experimental results of using pulse plasma to dispose nitrobenzene simulation waste water indicate that,the acidic condition,higher voltage pulse,import the oxygen toward the reactor and higher initial density are favourable for the nitrobenzene degeneration.The solution temperature after the reaction can be an attribute quantity for analyzing the pulse electric discharge intense degree.Under the condition of good electric discharge,the nitrobenzene degeneration is directly proportional to the finally solution temperature.The GC and MS analyses indicates that the pulse electric discharge in bubble water has a deep processing and low efficiency.
