【摘要】 采用湿式氧化技术处理在生产磺胺间二甲氧嘧啶过程中产生的高浓度有机废水。在反应温度为250℃,初始ρ(COD)为4 575 mg/L,反应时间为2 h,pH值为7~8时,采用湿式双氧水氧化和催化湿式氧化,COD去除率分别为78.3%和92.0%,表明催化湿式氧化具有较好的COD去除效果。同时考察了催化湿式氧化中反应温度、反应时间、废水pH值对COD去除率的影响。更多还原

【Abstract】 Wet oxidation technologies were used to treat high concentration organic wastewater from the production of sulfamethoxine.The removal rates of COD were 78.3% and 92.0% respectively by wet peroxide oxidation method and catalytic wet oxidation method when the reaction conditions were 250℃,initial ρ(COD) 4?575?mg/L,reaction time 2?h,and initial pH value 7-8.The removal efficiency of COD by the catalytic wet oxidation method was better.The main affecting factors on the removal of COD were investigated respectively,including temperature,reaction time,and initial pH value.更多还原
