RDX wastewater is a kind of wastewater containing energetic materials that is difficult to biochemically degrade. It is highly toxic and difficult to treat. In this paper, the synergetic treatment of RDX wastewater by ultraviolet light and three-dimensional electrode method is proposed. The optimum combination of 5mm carbon particles,28W UV lamp and 3cm distance between electrodes was used in the experiment. The optimal experimental conditions were finally determined as follows: pH value is 6.6, carbon particle addition is 7.0g, NaSO4 addition is 6.5g, electrolysis voltage is 7V, and reaction time is 70min. After 7 parallel experiments, the RDX removal effect is stable.
