以垂直流人工湿地小试系统为研究对象,探讨了不同位置(表层、上层、中层和下层)添加固体碳源对系统氮、磷及COD_(Cr)去除效果的影响.结果表明:湿地下层硝态氮去除率低于中层,最适宜碳源添加位置为垂直流人工湿地中、下层.添加碳源系统中,碳源添加位置为表层的系统COD_(Cr)去除率最高,各系统出水COD_(Cr)浓度均低于进水,不引起系统出水中COD_(Cr)浓度的增加.添加碳源显著提高脱氮除磷效果,碳源添加位置为下层的系统TN去除率最高,碳源添加位置为表层的系统氨氧化作用明显,出水铵态氮浓度最高,各系统对亚硝态氮和硝态氮去除率差异不明显,但对硝态氮都表现出良好的去除效果.碳源添加位置为下层的系统硝化作用最完全,TP去除能力也显著优于其他各系统.添加碳源至垂直流人工湿地下层可以达到同步脱氮除磷的效果. |

The optimum of carbon sources adding location and the effects of adding to different locations(surface, the upper, middle and lower layers) on the removal efficiency of nitrogen,phosphorus and COD_(Cr) were investigated in small-scale vertical flow constructed wetlands. The results showed that the removal efficiency of the nitrate nitrogen in the lower layer was lower than that in the middle layer,and the most suitable location for carbon sources supplement was the middle and lower layer of the vertical flow constructed wetlands. Among the systems with carbon sources added,the one which added the carbon sources to the surface layer exhibited the highest removal efficiency of COD_(Cr),and the concentration of COD_(Cr) of the effluent of each system were lower than the influent,not causing the concentration of COD_(Cr) increasing of the effluent of the systems. Adding carbon sources can significantly improve the removal efficiency of nitrogen and phosphorus. The system which added the carbon sources to the lower layer showed the highest removal efficiency of total nitrogen. The system which added the carbon sources to the surface layer showed significant ammoxidation,and the concentration of ammonia nitrogen of the effluent was highest. The removal efficiency of each system showed no significant difference in the removal efficiency of nitrite and nitrate nitrogen,and all showed great removal efficiency of nitrate nitrogen. The system which added the carbon sources to the lower layer showed the most complete nitrification,and the removal efficiency of total phosphorus was also significantly better than that of other systems. Adding carbon sources to the lower layer of the vertical flow constructed wetland can achieve the effect of simultaneous removal of nitrogen and phosphorus. |
