摘要
近年来,利用人工湿地技术修复水环境,进而建设湿地公园成为一大热点,但人工湿地工艺存在不容忽视的缺陷。成都市凤凰河二沟湿地公园创新性的采用人工快渗+表面流人工湿地组合工艺修复水环境,两者互为补充,互为强化,COD、BOD5、氨氮、TP去除率分别达85%～95%、85%～95%、95%～98%、70%～80%,即使低温环境污染物降解效果也很稳定。
In recent years,using constructed wetland for water environment remedy and then constructing wetland park has become a hotspot.However,the defects of constructed wetland can not be ignored.Constructed rapid infiltration and surface flow constructed wetland combined process was used innovatively for water environment remedy in the second trench of Phoenix River Wetland Park of Chengdu City.These two techniques strengthened each other complementary and mutually.The removal efficiencies of COD,BOD5,NH＋4-N,TP were 85%~95%、85%~95%、95%~98% and 70%~80%,respectively.The efficiencies were also stable,even at low temperatures.
