摘要
以低成本、易运维、生态效益好的人工湿地为研究对象,系统梳理其净化机理、系统类型及不同湿地类型对常规污染物的去除效能。研究结果表明,人工湿地通过物理作用主导悬浮物(Suspended Solids,SS)去除,化学作用核心去除总磷(Total Phosphorus,TP)与氨氮(NH3-N),生物作用主导化学需氧量(Chemical Oxygen Demand,COD)与总氮(Total Nitrogen,TN)去除;不同类型湿地适配差异化场景,其中复合湿地可通过组合实现效能优化。该研究可为人工湿地在污水处理厂尾水深度净化中的工程应用提供技术支撑。
Taking low-cost,easy to operate,and ecologically beneficial artificial wetlands as the research object,this study systematically sorts out their purification mechanisms,system types,and the removal efficiency of different wetland types for conventional pollutants.The research results indicate that artificial wetlands mainly remove Suspended Solids(SS)through physical processes,Total Phosphorus(TP)and ammonia nitrogen(NH3-N)through chemical processes,and Chemical Oxygen Demand(COD)and Total Nitrogen(TN)through biological processes;Different types of wetlands are adapted to differentiated scenarios,among which composite wetlands can achieve efficiency optimization through combination.This study can provide technical support for the engineering application of artificial wetlands in the deep purification of wastewater from sewage treatment plants.
