人工湿地处理污水中药品及个人护理品的效能研究进展

 药品及个人护理品在环境中具有“持久”、难生物降解、生物累积等特性，如何有效控制污水中的药品及个人护理品成为水处理领域所面临的重要难题之一。人工湿地作为一种生态污水处理技术，在药品及个人护理品的去除研究中逐渐受到关注。本文在总结了人工湿地与污水厂二级处理的对比效果、深度处理（二级处理后带UV处理）的对比效果研究后，得出人工湿地对污水中药品及个人护理品的处理效果与污水厂的处理效果相似或比其更好。对人工湿地的去除机制进行分析，发现光照、植物、基质和微生物等都不同程度地影响着人工湿地的去除效能。最后，对人工湿地处理污水中药品及个人护理品进一步的研究方向进行展望。

Progress in pharmaceutical and personal care products removal by constructal wetland

Pharmaceutical and personal care products(PPCPs) can be characterized by being persistent and non-degradable, and their bioaccumulation can be potentially harmful to the ecological environment. Proper and effective control of PPCPs in the sewage has become a major challenge for us. Known as an ecological wastewater treatment technology, constructed wetland is greatly concerned nowadays in the research of PPCPs removal. This paper starts with an overview which compares constructed wetland with its counterparts including wasterwater treatment plant(WWTP) and the advanced treatment (WWTP followed by UV treatment). Then it arrives at the conclusion that most of PPCPs removal efficiencies of the constructed wetland are as good as or even better than those of the conventional wasterwater treatment plants. The factors affecting the removal efficiency are analysed, and it is found that light, plants, matrix and microorganisms all contribute to the removal efficiency of PPCPs in a varying degrees. Finally, promising research directions of constructed wetland for removing PPCPs are predicted.
