中文摘要:
      采用催化臭氧化技术降解铀矿碱性浸出液中的有机物.由试验结果可知:单独臭氧化技术,有机物的降解率为15%;采用还原型催化剂(Ⅰ型:钒-二氧化锆-氮型;Ⅱ型:钒-二氧化硅-氮型;Ⅲ型:钒-二氧化钛-氮型),有机物的降解率为25%~30%,相对于单独臭氧化降解,降解率提高了14%~19%;采用氧化型催化剂(Ⅳ型:钒-二氧化锆-氧型;Ⅴ型:钒-二氧化硅-氧型;Ⅵ型:钒-二氧化钛-氧型),有机物的降解率为30%~65%,相对于单独臭氧化降解,降解率提高了21.8%、45.2%、53.7%;随着催化剂(Ⅵ型:钒-二氧化钛-氧型)用量的增大,有机物(CODCr)浓度越来越低,降解率逐渐升高,当用量大于0.8 g时,有机物(CODCr)降解率升高不明显,维持在60%~64%.
英文摘要:
      It sudies degradation of organic compounds in uranium alkaline leaching solution by catalytic ozonation technology.The test results show:single ozonation technology,organic matter degradation rate was 15%;the reduced catalyst (type I:vanadium-two zirconia-nitrogen type;type II:vanadium-silica-nitrogen type;type III:vanadium-titanium dioxide-nitrogen type),organic matter degradation rate of 25%~30%,relative to the ozonation,the degradation rate increased by 14%~19%;using oxidation catalyst (type IV:two vanadium zirconium oxide oxygen;V:vanadium-silica-oxygen;type VI:vanadium titanium dioxide and oxygen),organic matter degradation rate of 30%~65%,compared with ozonation,the degradation rate increased 21.8%,45.2%,53.7%;with the catalyst (type VI:vanadium-titanium dioxide and oxygen) content increased,organic matter (CODCr) concentration is lower and lower,the degradation rate increased gradually,when the content was more than 0.8 grams,organic matter (CODCr) degradation rate increased significantly,maintained at 60%~64%.
