- Comparison Study on Purification of Integrated Constructed Wetland in Living-water Garden between Spring and Summer

- 摘要:
- 依托成都市活水公园复合人工湿地系统，于2011年1-6月，对该人工湿地系统水流沿程主要水质指标（TN，NH3—N，TP，DP）进行监测及处理效果分析，以深入研究不同季节人工湿地水流沿程污染物的净化规律。结果表明：主要污染物总氮、氨氮、总磷及溶解性磷的去除率春季分别为45.5%，65.7%，77%，72.6%，夏季分别为56.9%，87.1%，76.9%，73.7%，对氮的去除效果存在季节性差异，而对磷的去除效果差异性不明显；并联的人工湿地塘床区左湿地系统各主要污染物净化效果明显高于右湿地系统，对氮、磷的去除率平均高4%和6%。研究认为，活水公园复合人工湿地系统春夏对不同污染物的净化存在季节差异，人工湿地塘床区不同植物组合与配置对人工湿地处理效果会产生一定的影响。
- Abstract:
- Water samples were regularly taken at six locations of the Living-Water Garden in Chengdu from January to June 2011 in order to study seasonal efficiency of constructed wetland in wastewater treatment. Water samples were analyzed for total nitrogen (TN), ammonia nitrogen (NH3—N), total phosphorus (TP) and dissolved phosphorus (DP). Removal rates of TN, NH3—N, TP and DP were 45.5%, 65.7%, 77% and 72.6% in spring, and 56.9%, 87.1%, 76.9% and 73.7% in summer, respectively, nitrogen and phosphorus removal efficiency were 4% and 6% higher in the left zone than in the right zone of the parallel wetland plant pond-bed area, indicating a seasonal difference in removal efficiency of nitrogen and no difference in removal efficiency of phosphorus.
