In this paper, uhrasonic cavitation helping zero-valent iron were employed to degrade TNT wastewater： The degradation efficiency was affected by factors such as the dosage of zero-valent iron, the pH value and the reaction time. The test results showed that the method of ultrasonic cavitation helping zero-valent iron could effectively degrade the TNT wastewater. The best removal efficiency of TNT and COI）~ separately reached up to 93.2% and 79.1%, under the conditions as follows： the ultrasonic frequency was 40kHz, the initial concentration of TNT was 150 mg/L, the pit value was 7, the dosage of zero-valent iron was 3.0 g and the reaction time was 40 min.
