城市降雨径流人工湿地处理的效能研究
Efficiency study of imoroved constructed wetland for urban runoff treatment
摘要
Abstract
According to the characteristics of urban runoff in the catchment of Tongsha reservoir, Dongguan City, Guangdong Province, an improved constructed wetland was employed to treat the simulated runoff in terms of pollutant degradation efficiency and the capacity of shock loading. The average concentrations of COD, TP,TN, NH4+-N in simulated wastewater were 169. 19 mg/L, 0. 58 nmg/L, 5.69 ag/L, 3.69 mg/L, and the removal efficiencies of the constructed wetlands system were 86.11％ , 82.1％ , 80.3％ and 76.7％ , respectively.The results indicated that the degradation process by the constructed wetlands was the synergistic effects of physical, chemical, and biological processes. The pollutant removal efficiency declined along the water flow direction, and most of pollutants were removed in the front of the system. The result of experiments under shock loadings revealed that the constructed wetlands had a strong resistance to shock loading,and it could bear short-term load of high concentration.关键词
