- 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.
