摘要
介绍了中新生态城人工湿地旁路净化景观水体并协同处理雨水径流的多功能集成设计方法、单元设施构成及运行模式,持续跟踪测试了2015年—2016年的工程运行效果。结果表明,非降雨期,人工湿地对景观水体中COD、NH_3-N、TP、叶绿素a的年均去除率分别由2015年的34.3%、24.3%、36.8%、53.3%升高至2016年的44.5%、31.4%、44.3%和58.3%,2016年出水COD满足《地表水环境质量标准》(GB 3838—2002)Ⅳ类水质要求,NH_3-N、TP均满足Ⅱ类水质要求,并且各指标去除率在年内均呈先升高后降低的趋势,7月份达到最高值。降雨期,人工湿地对雨水径流中SS、COD、NH_3-N和TP的平均去除率分别为93%、69.6%、44.8%和83%。
The integrated design method, facility units, and operating mode of constructed wet- lands for landscape water purification and rainfall runoff treatment in Sino-Singapore Tianjin Eco-city were introduced. The engineering performance was monitored in 2015 and 2016. The annual average removal rate of COD, NH3 - N, TP, and chlorophyll a in landscape water during the dry seasons raised from 34.3%, 24.3%, 36.8%, and 53.3% in 2015 to 44.5%, 31.4%, 44.3%, and 58.3% in 2016, re- spectively. In 2016, the effluent COD met the class IV standard in Environmental Quality Standards for Surface Water （ GB 3838 - 2002）, and NH3 - N and TP met the class 11 standard. Monthly, all removal rates increased firstly and then decreased, while reached the maximum in July. The average removal rate of runoff SS, COD, NH3 - N, and TP during the wet seasons were 93%, 69.6%, 44.8%, and 83% respectively.
