摘要
脱氮除磷是污水处理中的重点难点问题,人工湿地技术作为一种绿色生态的水处理技术,具有净化效率高、处理效果好、改善环境等优点,近年来在脱氮除磷方面得到了广泛的应用,而为了更好地研究人工湿地的脱氮除磷效果,数学模型和水环境模型被引入到人工湿地脱氮除磷的模拟.本文对人工湿地脱氮除磷的影响因素和用于人工湿地脱氮除磷模拟的模型进行了综述,总结了进水成分、环境条件、设计参数、运行参数等因素对人工湿地脱氮除磷效果的影响,归纳了衰减方程等数学模型和WASP模型、EFDC模型等水环境模型在人工湿地脱氮除磷模拟中的应用,指出了当前应用于人工湿地脱氮除磷模拟的主要模型存在的问题.
Nitrogen and phosphorus removal is a key and difficult problem in sewage treatment.Constructed wetland technology,as a green ecological water treatment technology,has the advantages of high purification efficiency,good treatment effect,can improve the environment,etc.In recent years,it has been widely used in nitrogen and phosphorus removal.In order to better study the nitrogen and phosphorus removal effect of constructed wetland,mathematical model and water environment model are introduced to simulate nitrogen and phosphorus removal in constructed wetland.This paper introduced the influencing factors of nitrogen and phosphorus removal in constructed wetland and the models used to simulate nitrogen and phosphorus removal in constructed wetland.It described the influences of influent composition,environmental conditions,design parameters,operating parameters and other factors on the nitrogen and phosphorus removal in constructed wetland.Moreover,this paper introduces the application of mathematical models such as attenuation equation,WASP model,EFDC model and other water environment models in the simulation of nitrogen and phosphorus removal in constructed wetland,and points out the existing problems of the main models used in the simulation of nitrogen and phosphorus removal in constructed wetland.
