摘要/Abstract

摘要： 实验采用Fenton试剂氧化-微电解-接触氧化组合工艺处理丙烯腈废水。研究了各单元工艺的最佳控制参数和操作条件。结果表明，在废水pH值为3左右、反应时间2 h的前提下，双氧水投加量40 mL/L，二价铁离子质量浓度为0.4 g/L，再经过微电解处理后的出水进入接触氧化阶段。在溶解氧为4.5 mg/L左右，水力停留时间为10 h、容积负荷1.0 kg COD_Cr/（m³·d）左右的条件下，出水COD_Cr小于100 mg/L，可达到国家对丙烯腈废水处理要求的一级标准。

Abstract: The combined process of Fenton reagent, Microelectrolysis and Biological contact oxidation is proposed to treat the Acrylonitrile wastewater. The optimal technological conditions and the effect of this process are discussed. The results show that by providing wastewaters pH of about 3 and reaction time of 2 hours, the quantity of H₂O₂ of 40 mL/L, the concentration of ferrous iron is 0.4 g/L, the effluent of microelectrolysis goes into Biological contact oxidation process, in which DO, HRT and volume load are 4.5 mg/L, 10 hours and 1.0 kg COD_Cr/(m³·d) respectively, satisfying the first grade of the national standard.

Key words: Acrylonitrile wastewater, Fenton reagent, micro-electrolysis, biological contact oxidation
