Abstract

Wastewater from dismantling level-5 bombs, explosives, and munitions contains high levels of 2,4,6-trinitrotoluene (TNT), intense color, and exhibits high toxicity and environmental persistence, making it difficult to treat by conventional methods. This study investigates the application of the UV/Peroxone process for TNT and color removal. Key factors, including pH, H₂O₂ concentration, UV intensity, reaction time, and recirculation rate, were examined. Treatment efficiency increased with H₂O₂ concentration, UV intensity, and recirculation rate, while initial pH had a negligible impact. TNT and color removals of 96% and 93%, respectively, were achieved, meeting QCVN 40:2025/BTNMT (column C) and TCVN/QS 658:2011 (column B) standards, demonstrating the process’s potential for practical application.
