摘　　要：受抗生素污染的医疗废水排放量逐渐增加,给人类生存环境和身体健康带来极大的危害。该文采用微波无极紫外耦合光催化降解米诺环素的模拟废水,研究了不同pH、H_(2)O_(2)投加量和TiO_(2)投加量对米诺环素去除的影响。在单因素的基础上,进行响应面的优化实验。结果表明:3个因素均能对米诺环素的降解性能产生影响,其影响的显著性为pH>TiO_(2)投加量>H_(2)O_(2)投加量;确定出微波无极紫外耦合光催化降解水中米诺环素的最优条件为pH 3.62、H_(2)O_(2)投加量5.48 mmol/L、TiO_(2)投加量0.47 g/L。在最优条件下,米诺环素的TOC降解率达到96.97%,与预测结果基本符合。The discharge of medical wastewater polluted by antibiotics increases gradually,which brings great harm to human living environment and health.In this paper,the effects of different pH,H_(2)O_(2) dosage and TiO_(2) dosage on the removal of minocycline were studied by using microwave electrodeless UV coupled photocatalytic degradation of simulated wastewater.On the basis of single factor,the response surface optimization experiment was carried out.The results showed that all three factors could affect the degradation performance of minocycline,and the significance of the influence was as pH>TiO_(2)>H_(2)O_(2).The optimal conditions of microwave electrodeless UV coupling photocatalytic degradation of minocycline in water were determined as pH 3.62,H_(2)O_(2) dosage 5.48 mmol/L,TiO_(2) dosage 0.47 g/L.Under the optimal conditions,the TOC degradation rate of minocycline reached 96.97%,which was basically consistent with the predicted results.
