Degradation of high concentration pharmaceutical wastewater by Microwave-Fenton system
Amounts of wastewater from the process of producing Penicillin are discharged nowadays.Experiments were carried out using Microwave-Fenton system and the influent qualides were as follows:the COD concentration was 32,100 mg/L,the BOD concentration was 12,450 mg/L.The effects of the microwave power,the radiation time.the quantity of the catalyst and the oxidant on the treatment efficiency were observed.The results showed that the microwave enhanced Fenton system had a better efficiency compared with pure Fenton oxidation system.When the microwave powet was 150 W.the radiation time was 9 mm。the removal of COD could reach 51.79％and the ratio of BOD/COD increased from 0.272 to 0.638 with the addition of 0.727,2∥L Fe(N03)3 as the catalyst and 1.5 m/L 3％H2O2 as the oxidant.Consequently,the Microwave-Fenton oxiclarion system had a good efficiency,and benefited the bio-degradation of the wastewater as well.
