摘　　要：本文采用铁碳微电解+Fenton处理二硝基丙烷模拟废水。首先,研究了单独铁碳微电解处理二硝基丙烷废水的效果,考察了铁催化剂的投加量、铁碳比对二硝基丙烷模拟废水COD去除率的影响。其次,考察了Fenton氧化技术中的H_(2)O_(2)投加量、FeSO_(4)·7H_(2)O投加量对二硝基丙烷模拟废水COD去除率的影响。最后,采用Fenton法进一步处理在铁碳微电解最优工况下的出水,考察了H_(2)O_(2)投加量、FeSO_(4)·7H_(2)O投加量对二硝基丙烷废水COD去除率的影响。实验表明,微电解+Fenton氧化组合工艺的最佳工艺参数为:在微电解最优工况下的出水基础上,H_(2)O_(2)投加量为1500 mg/L、FeSO_(4)·7H_(2)O投加量为1.99 g/L。对比了三种工艺的COD去除率,并进行了紫外-可见光光谱分析,得出了微电解+Fenton氧化组合工艺的可行性和高效性,COD去除率达到了98.5%,实现了二硝基丙烷废水的高效处理。In this paper,iron-carbon microelectrolysis+Fenton was used to treat dinitropropane simulated wastewater.Firstly,the treatment of dinitropropane wastewater by iron-carbon microelectrolysis alone was studied.The effects of iron catalyst dosage and iron-carbon ratio on the COD removal rate of dinitropropane simulated wastewater were investigated.At the same time,the effects of H_(2)O_(2) dosage and FeSO_(4)·7H_(2)O dosage in Fenton oxidation technology on COD removal rate of dinitropropane simulated wastewater were investigated.The results show that the optimum process parameters of micro-electrolysis+Fenton oxidation combined process are as follows:the effluent under the optimal condition of micro-electrolysis,H_(2)O_(2) dosage of 1500 mg/L,FeSO_(4)·7H_(2)O dosage of 1.99 g/L is the best working condition.The COD removal rates of the three processes were compared,and the UV-visible spectrum analysis was performed.The feasibility and efficiency of the microelectrolysis+Fenton oxidation combined process were obtained.The COD removal rate reached 98.5%,and the efficient treatment of dinitropropane wastewater was achieved.
