摘    要:针对染料中间体废水具有COD高、BOD5/COD低和具有生物毒性的特性,采用Fenton氧化-水解酸化-好氧组合工艺进行染料中间体生产废水的处理试验,试验结果表明:废水经Fenton氧化及水解酸化工序后,废水的BOD5/COD值由0.03升高至0.48,经好氧生化工序处理后的出水COD和BOD5浓度分别达122.6 mg/L和54.6 mg/L,符合《污水综合排放标准》(GB8978-1996)二级标准,该组合工艺COD总去除率达94%.

关 键 词:染料中间体废水  Fenton氧化  水解酸化  好氧处理

Abstract:According to the characteristics of dye intermediate wastewater,such as high COD concentration,low BOD5/COD,and biological toxicity,experiments on the treatment of dye intermediate wastewater were conducted by Fenton oxidation,hydrolytic acidification and aerobic combined processes.Experimental results show that the ratio of BOD5/COD goes up from 0.03 to 0.48 in wastewater treated by the procedure of Fenton oxidation and hydrolytic acidification and COD and BOD5 values in the effluent after aerobic treatment are 122.6 mg/L and 54.6 mg/L,respectively,the water quality satisfies the standard of grade 2 in Integrated Wastewater Discharge Standard(GB8978-1996).The COD removal rate reaches to 94% by the combined processes.
Keywords:dye intermediate wastewater  Fenton oxidation  hydrolytic acidification  aerobic treatment
