【摘要】 以草甘磷废水为研究对象,采用基于羟基自由基的改进型催化氧化—SBR工艺进行处理,取得良好效果。当催化氧化实验条件为:催化剂填充率为80%,氧化剂投加量为500 mg/L,pH为3,气水比为3,反应时间为90 min时,TP去除率达到90.7%;草甘磷废水经催化氧化处理后进入SBR反应器,停留时间为24 h时TP去除率达到77.3%;该组合工艺对TP去除率可达97.9%。更多还原

【Abstract】 The glyphosate wastewater has been treated by improved hydroxyl radical catalytic oxidation process— SBR process and pretty good effect is obtain.When the catalytic oxidation process conditions are as follows:catalyst filling rate is 80%,oxidants dosage is 500 mg/L,pH is 3,ratio of air to water is 3,and reaction time is 90 min,the TP removing rate is 90.7%.After the glyphosate wastewater has been treated by catalytic oxidation process and got into SBR reactor,and the HRT is 24 h,the TP removing rate will be 77.3%.By the combined catalytic oxidation—SBR process,the TP removing rate is 97.9%.更多还原
