基于微气泡的O3-H2O2体系对布洛芬的降解研究
Study on the Degradation of Ibuprofen by Microbubble Technology Coupled with O3-H2O2 System
摘要
Abstract
Ibuprofen(IBP),as an important drug and personal care substance,is widely used in the pharmaceutical and chemical industries.Because of its biological toxicity and difficult degradability,it has become one of the important potential environmental pollutants.In this study,ibuprofen wastewater was used as the object and aimed at the problem of low efficiency of IBP oxidation by traditional O3 oxidation technology,O3 coupled with microbubbles and H2O2 was used to optimize the oxidation system.By simulating the effects of ozone dosage,H2O2 concentration and common chemical parameters of wastewater on the degradation efficiency of IBP and ozone concentration in aqueous phase in the coupled system,combined with GC-MS intermediate product analysis,the optimal treatment process parameters and degradation pathway of IBP in the coupling system were explored.The results showed that the degradation effect of O3 on IBP could be greatly improved by dispersing O3 in the form of microbubbles and coupling with H2O2.When the concentration of H2O2 was 0.3 mmol/L,ozone dosage was 8.8 mg/min and pH was 8.0,the degradation rate of IBP by MB/O3-H2O2 was up to 52.3%.HCO3-/CO32-would inhibit the degradation of IBP.In the MB/O3-H2O2 system,the oxidation of IBP precursor was mainly direct ozonation,while the further oxidation of ozonation products was achieved by·OH.关键词
