Abstract: TNT which structure is stable and wastewater is poisonous to the biology, is difficult to be bio-degraded. The electro-hydraulic pulse discharge/iron-inner-electroanalysis was used to treat TNT wastewater. In the experiment, the mass of iron adding to reactor, pH and iron reuse times were investigated, which discharge voltage was 36 kV, TNT wastewater concentration was 90 mg/L and volume was 7 L. The experiment results are as follows: when the mass of iron was 700 g and pH=6.5, the TNT degradation was 97.7%. The degradation remained when iron was reused 6 times. TNT was degraded all the same after discharges. TNT wastewater which volume was 115 L and concentration was 50 mg/L, were treated in the reactor of 125 L, the maximum of TNT degradation was 94.2%, which concentration reduced to 2.9 mg/L.
