摘要
介绍国内外人工湿地处理技术的研究现状及人工湿地对有机物、氮、磷等的去除机理及效率,分析了人工湿地处理技术存在的不足。提出人工湿地污水处理系统作为一种高效、节能、低投资、运行费用低、操作简单的污水处理技术在我国尤其是中小城镇及广大农村具有应用前景。
In the paper, Research actuality of internal and external of constructed wetland wastewater treatment was introduced. The removal mechanisms and dispose efficiency of organic pollutants, nitrogen, phosphorus of constructed wetland are analyzed in detail. And exist insufficiency of constructed wetland is analyzed. Constructed wetland as a wastewater treatment technology had advantage of nigh efficiency, less energy dissipation, low invesatment, cheap cost and simple operation, which was suitable for China, especially the rural areas and small cities.
