Abstract

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.

Key words: Mengqing Garden, landscape water eco-compositive purifying process, single factor assessment, fuzzy comprehensive assessment (FCA)
