摘要 利用微波-Fenton联合工艺对二甲基砜(DMSO)废水进行处理,探讨了pH、微波辐照功率与时间等因素对其去除率的影响。结果表明,对于质量浓度为50 g/L的DMSO废水(无需调整pH),采用240 W微波辐照5 min,在H2O2投加量为 5 mL/min、Fe2+/H2O2摩尔比为1/16时,DMSO去除率最高达98.85%。利用SBBR法对微波-Fenton法处理后残留的DMSO废水进行进一步处理,正常运行工况下对质量浓度1.1 g/L以内的DMSO废水的去除率稳定在90%以上。

Abstract: A microwave enhanced sensitized Fenton system is used for treating DMSO-containing wastewater.The effects of microwave irradiation time,microwave power,pH value,H2O2 dosage,dosing method,and Fe2+/H2O2 molar ratio on the removal rate of DMSO are explored.It is found that the removal rate of DMSO from wastewater can reach as high as 98.85% when the initial mass concentration of DMSO-containing wastewater is 50 g·L-1,microwave irradiation lasts for 5 min,microwave power is 240 W and H2O2 dosage is 5 mL·min-1,the molar ratio of Fe2+/H2O2 is 1/16 and pH is not adjusted.The residual wastewater after treatment by microwave-enhanced Fenton method is further treated by SBBR method,and the removal rate of DMSO from wastewater with a mass concentration lower than 1.1 g·L-1 is stable above 90% under normal operation conditions.
