摘要
为了研究高级氧化技术对含黑索今(RDX)的炸药工业废水的处理效果,本文采用O3、O3/H2O2、O3/H2O2/UV 3种氧化工艺分别对废水中的RDX进行了降解试验,并对比分析了3种工艺的处理效果和机制。结果表明:O3/H2O2、O3/H2O2/UV工艺对RDX的去除率明显优于O3工艺;提高体系的pH值将有利于RDX的降解;随着RDX初始浓度的增加,RDX的去除率呈现下降趋势;投加H2O2和UV照射可提高臭氧的利用率,且O3/H2O2/UV工艺催化臭氧分解的能力比O3/H2O2工艺强。
The efficiency of super oxidation methods to degrade RDX in explosive industry wastewater is studied by related experiments using O3, Oa/H2 02 and Oa/H2 02/UV, and the effects and mechanism of RDX removal are an- alyzed. The results show that the removal rates of RDX using 03/H2 02 and Oa/Hz 02/UV are higher than that of 03, increasing the pH of wastewater is conducive to the RDX degradation, and the removal rate of RDX decreases with the increase of the initial concentration of RDX. The utilization of 03 increases when H2 02 and UV are added. The decomposition capacity of 03/H2 02/UV is better than that of 03/H2 02.
