人工湿地外加植物碳源强化脱氮的应用探讨

摘要

综述了国内外人工湿地外加植物碳源强化脱氮的研究进展，从脱氮效果、脱氮费用和 CO2排放量的角度，分析得出植物碳源比小分子碳源更具明显的优势，并结合其降解难易程度，筛选出了更适合外加碳源的植物。%In this PaPer,the research Progress of enhanced nitrogen removal from artificial wetlands at home and abroad was reviewed. From the nitrogen removal,removal of nitrogen costs and CO2 emissions summed uP the advantage of Plant carbon source comPared to small molecular car-bon source. And comPared with the degree of degradation the more suitable Plant for additional carbon source is filtered out.
