人工湿地脱氮除磷强化技术研究

人工湿地作为一种新型污水生态处理工艺受到越来越广泛的重视,现在广泛应用于各类水体的处理,然而在实际应用中存在脱氮除磷效率偏低等问题,在一定程度上限制了应用,如何强化人工湿地脱氮除磷已成为近年来的研究热点.本研究从人工湿地工艺改进和创新、基质的选择与优化、植物的筛选与配置、设计及运行参数的优化等方面详细论述了人工湿地强化脱氮除磷技术,以期提高人工湿地脱氮除磷效率,为人工湿地技术优化与工程应用提供参考.

AugmentationTechnologies of Nitrogen and Phosphorus Removal in Constructed Wetland

As a kind of wastewater treatment technology, constructed wetland has been wildly used in different types of wastewater treatment, but some problems such as low efficiency of nitrogen and phosphorus removal exist in application, and limit its application. How to enhance nitrogen and phosphorus removal by constructed wetland is one of research hot spots in recent years. This study analyzed the augmentation technology of nitrogen and phosphorus removal, including process improvement and innovation, matrix selection and optimization, plant selection and configuration, design and optimization of operation parameters etc. , so as to improve the efficiency of nutrient removal in constructed wetland and provide reference for the optimization and engineering application of constructed wetlandtechnique.
