摘要
用Fenton试剂对硝苯地平医药废水进行氧化处理实验研究,探讨了n(H2O2)∶n(Fe2+)、H2O2浓度、pH、温度和反应时间对模拟废水COD去除率的影响。结果表明,当n(H2O2)∶n(Fe2+)=5∶1,30%的H2O2用量为0.4 mL,溶液pH=2.5,反应时间为24 h时,在20℃、120 r/min条件下,废水COD去除率可达74.5%,BOD5/COD从0.10提高至0.31,可生化性得到较大提高,为后续的生物处理创造了条件。
Fenton reagent has been used for treating the wastewater from medication nifedipine production. The effects of n（H2O2）：n（Fe^2＋）, H2O2 concentration, pH, temperature and reaction time on the COD removal rate of simulated waster are discussed. The results show that COD removal rate of the wastewater reaches 74.5% and BODJCOD has increased from 0,10 to 0.31, when n （H2O2）：n （Fe^2＋） = 5：1, H2O2（30% ） 0.4 mL, solution pH 2.5, reaction time 24 h, temperature 20 ℃, 120 r/min. It indicates that the biodegradability has been improved greatly, and created the conditions for the following biological treatment.
