Long-term performance of nutrient removal in an integrated constructed wetland

Popis výsledku v původním jazyce

Constructed wetlands have been regarded as efficient technologies for both wastewater treatment and reuse of water resources. Most studies on CW treatment efficiency are limited to a short term perspective, and there are still many unknowns about the long term performance of CWs. Here we evaluated the performance of an integrated CW that has been in operation formore than ten years. The average removal rates of TN and TP were maintained at 53,6 and 67,3 percent over 10 years, respectively. The annual mass reductions in TN and TP reached 937,5 kg ha yr and 303,2 kg ha yr, respectively. In addition, TN removal rate was significantly higher in summer and autumn than those in spring, yet there was no seasonal difference in TP removal. The bacterial richness and diversity in summer and autumn were higher than those in spring. TN and TOC not only determine the bacterial community structure, but also affect the removal efficiency of CW. Denitrification and dephosphorization microorganisms were enri
