  • 摘要: 考察了改性活性炭吸附-催化臭氧氧化对炼化RO浓水中有机污染物的降解效果。结果表明，花生壳经H3PO4活化后具有较好的比表面积及孔径结构，再经Cu2+、Mn2+、Fe3+溶液负载改性，得到花生壳活性炭催化剂，其中Cu2+改性后的活性炭具有最大的比表面积。将不同的改性活性炭与臭氧组合处理RO浓水，COD去除率显著提高，表现为Cu-AC≥Mn-AC > Fe-AC > H3PO4-AC，偏碱性条件和提高活性炭投加量均利于活性炭吸附-催化臭氧氧化反应，且在30 min后COD去除率趋于平稳。当利用金属离子负载改性活性炭时，臭氧消耗率显著提高。其中，Cu-AC和Mn-AC吸附-催化臭氧氧化时臭氧的消耗率较高，COD去除率≥80%，出水COD-1，达到国家一级排放标准。
    Abstract: The degradation of organic matter in RO concentrate by adsorption-catalytic ozonation was investigated in the presence of modified peanut activated carbon.The activated carbon was initially made from peanuts modified by H3PO4,followed by mixing,modifying,and loading with Cu2+,Mn2+,and Fe3+ solutions.The metal-ion loaded activated carbon showed high specific surface area and total pore volume,in particular the activated carbon modified by Cu2+.As the modified activated carbon was used in the ozonation of the RO concentrate,the COD removal was enhanced significantly,which indicated Cu-AC≥Mn-AC > Fe-AC > H3PO4-AC.In addition,the COD removal efficiency of the combined ozonation and activated carbon adsorption was increased for basic samples with a high activated carbon dosage.As the reaction time went beyond 30 min,the COD removal increased slightly.Furthermore,the presence of metal-ion-loaded activated carbon significantly increased the ozone consumption.Among the three kinds of modified activated carbon,Cu-AC and Mn-AC consumed more ozone and had higher COD removal efficiencies of above 80%,which caused the below 60 mg·L-1 effluent COD to meet the national discharge standard.
