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 metalion 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.关键词
