潜流人工湿地氮素去除机理与影响因素

摘要

The nitrogen removal mechanisms and transformations are summarized.It is indicated some novel routes for enhancing nitrogen removal.Based on the overview,the effect of environmental factors (i.e.temperature,pH,availability of organic carbon,DO) and operational conditions (i.e.retention time,nitrogen loading,recirculation,influent feed) on nitrogen removal have been investigated and optimized.%综述了氮化合物去除的机理和转化规律,指出提高氮素去除率的新途径.在研究了温度、pH值、溶解性有机碳、溶解氧等因素的基础上,以及水力停留时间、氮负荷、回流、进水方式等的配置模式的概述,来探究环境因素和运行条件对潜流人工湿地除氮效果的影响.
