微波强化Fenton/活性炭工艺处理制药废水的影响因素

为了研究微波强化Fenton/活性炭工艺处理高浓度制药废水的影响因素,以阜新某集团公司生产制药原料排出的废水为研究对象,利用静态实验,采用混凝-微波强化Fenton/活性炭工艺对高浓度制药废水进行实验。实验用水为100 mL、COD为576~1 440 mg/L的制药废水,当活性炭投加量为2 g,H2O2投加量为3/4Qth,pH值为5,微波辐照功率和时间分别为500 W和7 min时,COD去除率可达到92.6%,出水COD在42.6~106.6 mg/L范围内。实验结果表明,活性炭的投加量、H2O2的投加量、pH值、微波辐照功率和辐照时间对微波强化Fenton/活性炭工艺的处理效果影响都较显著。

Influencing factors of microwave enhanced Fenton/active carbon process for pharmaceutical wastewater

The influencing factors of high concentration pharmaceutical wastewater treatment by microwave enhanced Fenton/active carbon process were researched. The wastewater of pharmaceutical materials produced by a company in Fuxin was considered as the raw water. The experiment was a static test. The high concentration pharmaceutical wastewater was tested by the coagulation-Fenton/active carbon process which was enhanced by the microwave. The test water was the pharmaceutical wastewater with the volume of 100 mL and the COD of 576~1 440 mg/L. The experiment showed that the removal rate of COD could reach to 92.6% with the effluent COD being in the range of 42.6~106.6 mg/L when the dosage of activated carbon was 2 g,H₂O₂ was 3/4Q_th. The pH value was 5 and the microwave irradiation power was 500 W for 7 min. The test results showed that the dosage of activated carbon,the dosage of H₂O₂,the pH,the microwave irradiation power and the irradiation time significantly influenced the microwave enhanced Fenton/active carbon process.
