摘　　要：针对浙江省档案局内典型城市微污染景观水体,构建了以沉水植物+生物操纵为核心、入湖植物削减带+曝气造流辅助工艺为主的示范工程。该工程经过1年的设计、建设、运行,实际监测数据表明,出水COD_(Mn)、NH_(4)^(+)-N均优于《地表水环境质量标准》(GB 3838—2002)Ⅰ类标准,对COD_(Mn)和NH_(4)^(+)-N去除率分别为88.61%和95.45%;TN达到了准Ⅰ类标准;景观水体透明度>1 m。冬季水体TP浓度有所升高,有待进一步监测和进行机理分析。A demonstration project was constructed with submerged plants and biological control as the core,as well as lake-entry plant reduction zone and aeration flow generation as the auxiliary technology for typical urban micro-polluted landscape waters in Zhejiang Provincial Archives Bureau.After one year of design,implementation and operation,the monitoring data show that the effluent COD_(Mn) and NH_(4)^(+)-N are better than those of levelⅠin Environmental Quality Standards for Surface Water(GB 3838-2002).The removal rates of COD_(Mn) and NH_(4)^(+)-N are 88.61%and 95.45%respectively.The TN reaches to the quasi-Ⅰlevel and the landscape waters transparency is greater than 1 m.The concentration of TP increased in winter,which needs further monitoring and mechanism analysis.
