摘要：针对流域水体富营养化加剧和二级处理水氮磷指标较高的问题,提出以人工湿地对二级出水继续低耗、理想地脱氮除磷。研究中通过对照不同进水水质条件下,不同结构人工湿地的脱氮除磷效能,探讨了人工湿地内的主要脱氮除磷途径。研究表明,表面流湿地内植物对氨氮吸收/吸附和硝化过程为主要氮转化途径,潜流湿地内直接反硝化过程为主要脱氮途径,脱氮效率30%～40%;磷在人工湿地内主要依赖除磷填料床的物化吸附、共沉淀去除,除磷效率达80%以上。
In order to relieve the eutrophication of drainage-area water bodies, the advanced removal of N/P in secondary effluent is considered necessary and the constructed wetland is taken as the efficiency and low cost process to remove N/P. Based on the above viewpoints, the N/P removal characteristics in different kinds of constructed wetlands have been analyzed. The results of this study have indicated that ammonia-nitrogen removal by adsorption of plant and nitrified is the main nitrogen removal process in surface flow wetland, the nitrate-nitrogen removal by denitrification is the main nitrogen removal process in subsurface flow wetland, and the dephosphorization by physicochemical sorption or adsorption by packings bed is the main P removal process in subsurface flow constructed wetland. The above N/P removal could reach respectively 30%～40% and 80%.
