摘要
人工湿地作为一种新型的处理技术,在水环境保护中具有重要的意义和广阔的应用前景。然而目前人工湿地的设计和运行主要是建立在统计数据和经验公式的基础上,对人工湿地去除污染物的内在机制尚缺乏定量化的认识。通过对潜流人工湿地氮循环生态动力学模型的研究,系统地分析了潜流人工湿地中氮素的去除机制,对将来完善人工湿地处理技术的设计、运行和预测方法具有一定的借鉴意义。
As a new treatment technology,constructed wetland has an important significance and a widely applied prospect in the water environmental protection.The design and operation of the constructed wetland are still on the basis of the statistical date and the empirical formula.The removal of pollutants in the constructed wetland is not yet completely understood.Through researching on the ecological kinetic model of nitrogen cycle in the subsurface flow constructed wetland treatment system,the paper analyzes the removal way of nitrogen in the constructed wetland in detail.It can act as a reference to establish the method of the design and operation and prediction for the constructed wetland treatment system.
