【摘要】 梦清园景观水体生态净化系统对苏州河河水进行处理后排放,根据2017年3月-11月的水质监测数据,采用单因子评价法以及模糊综合评价法分别对苏州河河水和景观水体生态净化系统的水质类别进行评估.结果表明,该处理工艺对NH3-N、TN和TP等指标有一定的去除率,分别为29.7%、55.2%和24.3%,溶氧浓度有很大提升,但各单元水质波动较大,其中由于植物堆积、内源释放、基质饱和等原因,芦苇湿地的水质最差(劣V类),需要加强管理维护以恢复水体净化效能.更多还原

【Abstract】 Located on the south side of Suzhou River,an eco-compositive purifying process is run in Mengqing Garden to treat landscape water.Single factor assessment and fuzzy comprehensive assessment（FCA）were utilized to evaluate the water quality classification,respectively.The results showed that the system reduced the concentration of NH₃-N,TN and TP,with removal rates of 29.7%,55.2%,and 24.3%,respectively,and DO was greatly elevated.The water quality fluctuated throughout the process.The water quality of the Reed Wetland was the worst,inferior to Class V and requires improved management.更多还原
