水力停留时间对人工湿地净化城市湖泊水体影响
Effect of Hydraulic Retention Time on Water Purification of Urban Lakes by Artificial Wetland
摘要
Abstract
Taking the Xingqing Lake in Xi' an city as the studied object, referring to the relevant literatures in the world, the paper summarized and analyzed the definition, classification, composition and purification mechanism of the artificial wetland, and expounded the research status of artificial wetland at home and abroad. This experiment consulted the water quality of mixed wastewater that discharged into the Xingqing Lake, disposed the wastewater by using the artificial wetland of horizontal undercurrent type, and determined the removal efficiency of chemical oxygen demand, total nitrogen, total phosphorus and ammoniacal nitrogen under the conditions of different hydraulic retention time. The results showed that the hydraulic retention time was the main factor which impacted the treatment effects of the artificial wetland, commonly, the removal efficiency of the pollutants increased with the increase of hydraulic retention time.关键词
