| 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 3mmol/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. |
