In view of the highly toxic and hard-to-treat nature of the TNT wastewater generated in the scrap ammunition disposal process, the properties and the current treatment of TNT wastewater are analyzed. The method of TNT wastewater treatment based on high voltage pulse plasma is put forward. The mechanism of wastewater degradation and treatment under the working of pulse plasma is analyzed, and the design scheme of bipolar pulse power and the solid-liquidgas reactor are presented. The research shows that the treatment efficiency of TNT wastewater is improved based on the pulse discharge plasma,and it can be used to solve the problem of TNT wastewater treatment in the scrap ammunition disposal.
