摘要: 人工湿地在处理高氮低碳污水时往往存在碳源不足的困境，可采用外加碳源的方法提高人工湿地脱氮效率。本文总结了人工湿地外加碳源的种类及效果，比较了各种碳源性能优缺点、改良方法以及投加方式等。目前用于人工湿地外加碳源的材料主要有：低分子碳水化合物，天然有机底物，可生物降解的高分子聚合物等。选择高效碳源及合适的投加量、投加方式是提升人工湿地脱氮效率的可行手段。
Abstract: When it comes to the treatment of high nitrogen and low carbon sewage, constructed wetlands (CWs) are always inefficient due to a lack of carbon source. Since adding external carbon can improve the denitrification performance, we summarize the pros and cons of different carbon sources. We also compare their efficiency, strengthening methods as well as the modes of dosage. In the precedent studies, common carbon sources are smaller hydrocarbons, plant debris and biodegradable high-molecular polymers. Choosing the effective carbon source and proper dosing methods can promote the denitrification of CWs.
