摘　　要：采用超声/Fenton试剂联合技术对头孢噻肟钠模拟制药废水进行处理,实验证明这种联合技术对有机污染物的降解是有效的。实验条件:c(Fe2+)=14.31×10-5mol/L,c(H2O2)=5.94×10-3mol/L,曝气量为0.05 m3/h;pH=3时,Fenton试剂预处理5 min;pH=12时,超声作用48 min,最后静置2 h,超声/Fenton联合技术作用COD去除率为44.1%,BOD5/COD值可达0.99,为后续生化处理提供有利条件。The applicability of ultrasonic decomposition of cefotaxime sodium simulated pharmaceutical wastewater by combined use of Fenton reagent was investigated The result shows that the combining technology treating the cefotaxime sodium simulated pharmaceutical wastewater is efficient. When the concentrations of Fe^2＋ and H2O2 are respectively 14. 31× 10^-5 mol/I, and 5.94 × 10^-3 mol/L,the aeration flow is 0.05 m^3/h,the wastewater is pretreated by Fenton reagents in 5 minutes at pH=3 and treated by ultrasound in 48 minutes at pH=12, finally is standed for 2 hours. The overall COD removal and BOD5/COD are respectively 44. 1% and 0. 99. The more important is that the effluent of treated wastewater is favorable to sequencing biological treatment because of its high biodegradability.
