抗生素与重金属复合污染废水处理的研究进展

随着越来越多的污染物进入环境，水体抗生素和重金属复合污染问题已引起学者们的关注.在归纳和总结抗生素和重金属相互作用机理的基础上，综述了抗生素和重金属复合污染废水主要处理技术的研究进展，并总结了其作用机理及优缺点.结果表明:抗生素和重金属的相互作用主要受到抗生素官能团的种类、重金属离子的类型和溶液pH的影响；吸附法是当前应用最多的方法，而光催化法和人工湿地法具有广阔的应用前景，将絮凝剂或零价铁基改性能够增强抗生素和重金属复合污染废水的处理效果，各种方法相结合对处理水体抗生素和重金属复合污染有较大潜力.建议今后研究应着重关注以下几个方面:①各种处理技术在实际环境水体中的应用；②复合污染的环境影响及相关法规标准的制订与完善；③新污染物抗性基因的生成机理及其影响因素. 

Research Progress in Treatment of Antibiotics and Heavy Metals Compound Polluted Wastewater

As more and more pollutants enter the environment, the compound pollution of water by antibiotics and heavy metals has attracted the attention of scholars. Based on the analysis of the interaction mechanism between antibiotics and heavy metals, the research progress of the main treatment technologies of wastewater polluted by antibiotics and heavy metals is reviewed, and the mechanism of action and advantages and disadvantages are summarized. The results showed that the interaction between antibiotics and heavy metals was affected by the types of functional groups, the types of heavy metal ions and the pH of the solution. Adsorption is currently the most used method, and photocatalysis and constructed wetland methods have broad application prospects. The modification of flocculant or zero-valent iron can enhance the treatment effect of wastewater with combined antibiotics and heavy metal pollution. The combination of various methods has great potential for treating combined pollution of antibiotics and heavy metals in water. It is recommended that future research should focus on the following aspects: (1) The application of various treatment technologies in actual environmental water bodies; (2) The environmental impact of complex pollution and the formulation and improvement of relevant laws and regulations; (3) The generation mechanism and influencing factors of emerging pollutant resistance genes.
