|
摘要
目的研究三维电极-电Fenton法降解孔雀石绿废水的处理效果及各因素对废水色度和COD去除率的影响.方法控制反应时间、初始pH值、电解质种类和质量浓度、电解电压、极板间距和曝气强度,分析色度和COD去除效果.结果单因素试验结果表明:色度为500~600倍,COD质量浓度为500~600 mg/L的孔雀石绿废水在pH为3,电解质Na2SO4质量浓度为5 g/L,电压16 V,极板间距9 cm,曝气强度为0.8 L/min的条件下反应120 min,脱色率和COD去除率分别达到了91.97%和70.61%,出水色度为40.67倍,出水COD质量浓度为149.69 mg/L.满足《纺织染整工业水污染物排放标准》(GB4287—2012)间接排放标准.结论三维电极-电Fenton法能够有效处理孔雀石绿染料废水,对废水的色度和COD均有较高的去除率.
In order to explore the effect of degradation of malachite green wastewater by three-dimensional electro-Fenton process and the influence of various parameters on the decoloration and COD removal rates of wastewater,the effects of reaction time,initial pH value,type and concentra-tion of electrolyte,electrolytic voltage,plate spacing and aeration intensity on the decoloration rate and COD removal rate were analyzed.The results of single factor test showed that,under the conditions of initial pH 3,Na_2SO_4 dosage 5 g/L,voltage 16 V,plate spacing 9 cm,aeration intensity0.8 L/min and reaction time 120 min,the decolorization rate and the COD removal rate were91.97% and 70.61% respectively,the effluent chroma was 40.67 times,and the effluent COD concentration was 149.69 mg/L when the initial chroma was 500 ~ 600 and initial COD was500 ~ 600 mg/L,meeting the indirect emission standard of 《Discharge standards of water pollutants for dyeing and finishing of textile industry 》(GB4287—2012).Three-dimensional electrode electro-Fenton process can effectively treat malachite green dye wastewater,and has a higher removal rate of chroma and COD.
