| 摘 要： | 针对偶氮类有机物废水具有色度大,难降解的特点,以对二甲基氨基偶氮苯磺酸钠(甲基橙)为模拟研究对象,对水体系中铁炭微电解-Fe2+/K2S2O8降解甲基橙的方法进行了研究。通过正交实验确定出该方法各因素的影响程度,进一步通过单因素影响实验确定该方法的最佳条件是:铁炭微电解填料、FeSO4和K2S2O8投加量分别为300 g/L、1.3mmol/L和0.7 mmol/L,初始pH值为7.0。在最佳条件下,甲基橙COD和色度去除率分别能达到64.7%和68.2%。

| Abstract: | In view of high chroma and hard degradation of the azo organics wastewater, taking methyl orange as the simulated research object, the method for degradating methyl orange in water by iron carbon micro-electrolysis packing, K2S2O8 and FeSO4 was studied. An orthogonal experiment was carried out to study the respective effects of different factors. Through a further single factor experiment, the optimum conditions of the method were determined as follows, iron carbon micro-electrolysis packing dosage of 300 g/L, FeSO4 dosage of 3 mmol/L, K2S2O8 dosage of 0.7 mmol/L, and the initial pH value of 7.0. Under the optimum conditions, the removal rates of methyl orange COD and chroma can reach 64.7% and 68.2%, respectively. |
