超声波催化臭氧去除滤后水中有害有机物

US/O_3 Removal of Hazardous Chemicals from Filtered Water

文章以松花江水为原水,研究其滤后水的深度处理,包括臭氧氧化、超声波处理及超声波催化臭氧氧化工艺。研究重点为有毒有害有机物(POPs)在深度处理前后的变化。采用GC-MS进行了定性与半定量分析。结果表明超声波催化臭氧氧化对有毒有害类物质有非常明显的去除效果。超声处理、臭氧氧化、超声波催化臭氧氧化10min后有毒有害有机物的去除率高达62.8%、88.0%、90.6%;其中内分泌干扰物(EDCs)的去除可分别达到17.88%、5.77%和94.93%。可见超声波催化臭氧氧化对有毒有害及内分泌干扰类物质去除有十分明显的优势。

Advanced treatment technologies including sonication,ozonation and sonication/ozonation using the filtrate from source water of Songhua River were studied to investigate the control of hazardous organic materials.GC-MS was sued to quantify the organic substrates.Results showed that sonolysis,ozonation and US/O3 were all effective in degrading the poisonous and harmful matters.After 10min oxidation,the removal efficiency of harmful substances reached 62.8%,88.0% and 90.6% respectively while removal efficienc...
