粉煤灰对磺胺嘧啶抗生素污染地下水的修复效果研究
Study on the Remediation Effect of Fly Ash on Groundwater Contaminated by Sulfadiazine Antibiotics
摘要
Abstract
Since the large-scale use of sulfadiazine causes water environmental pollution,how to effectively remove sulfadiazine has become a research hot spot.Permeable reactive barrier as an in-situ remediation technology for groundwater pollution has received widespread attention in recent years.Finding efficient medium materials is the key to permeable reactive barrier technology.In this paper,the adsorption and migration properties of fly ash on sulfadiazine were studied through static batch experiments and simulated dynamic column experiments of permeable reactive barrier reactors;the structural characteristics and properties of fly ash were determined by scanning electron microscopy and infrared spectroscopy,and the adsorption process of fly ash on sulfadiazine was analyzed.The research results show that the surface of fly ash is rough and the specific surface area is large,which provides abundant adsorption sites for the adsorption of sulfadiazine on fly ash.In the process of fitting the static adsorption characteristics,the Freundlich equation has the best fitting effect;when the concentration of sulfadiazine is 5 mg/L,the removal rate reaches 85%.The research results can provide a certain reference for the material selection of permeable reactive barrier technology in the remediation of groundwater antibiotic pollution.关键词
