摘要
为研究臭氧(O3)对含黑索今(RDX)的炸药废水的处理效率,向RDX废水连续通O3进行试验,采样分析RDX浓度、化学需氧量(COD)等。结果表明:浓度为3.0 mg.L-1的O3氧化10 mg.L-1的RDX 2 h可使RDX去除58.01%;pH=12,O3氧化4 h可除去约83.15%的RDX;提高废水的pH值、降低RDX浓度及提高温度均利于O3氧化效率的提高。可见,对于pH值较高、浓度较低的RDX废水,单独利用O3氧化法处理是可行的。
The efficiency and the affecting factors of ozone oxidization for explosive wastewater containing RDX were studied by related experiments with letting continuously O3 into the water. The concentration of RDX and COD value of the wastewater were monitored during the process of oxidization. The results show that 3.0 mg · L^-1 O3 makes 10 mg · L^-1 RDX remove 58.01% through oxidation of 2 h, and when pH value equals to 12,O3 removes 83.15% RDX through oxidation of 4 h. At the same time, increasing pH value and temperature, decreasing RDX concentration are useful to increase the RDX removal efficiency by ozone oxidization. Therefore,ozone oxidization processes are suitable for treating the RDX wastewater with high pH value and low concentration of RDX.
