(1)2H2O2→O268:32质量浓度比:H2O2:COD=2:1,是大概比值,实际为2.125:1。COD是以耗氧(O)量计1L废水:COD10000mg/L:10000mgO→20000mgH2O2(纯)→20000/30%=66667mgH2O2(原)=66.67gH2O2(原)→60.06ml/LH2O2(原)=60.06L/m3H2O2(原)→60.06元/m3质量分数30%的H2O2,密度=1.11g/cm3,价格1000元/吨=1000元/m3=1元/L。1L废水→10000mgO→0.3125molO2→0.625molH2O2→21.25g纯H2O2→70.83g原(有杂质的)H2O2→63.82ml/LH2O2(原)(2)按照质量浓度双氧水:COD=1:1,摩尔浓度Fe2+:H2O2=1:3换算。去除废水COD10000mg/L=COD10g/L则加双氧水质量浓度10g/L,30%双氧水密度=1.11g/cm3,则30%双氧水体积为30.03ML.摩尔浓度Fe2+:H2O2=1:3双氧水10g→0.2941molH2O2→0.098molFe2+→0.098molFeSO4.7H2O→27.244gFeSO4.7H2OFeSO4.7H2O(278g/mol)
