Design and performance of a filtration-adsorption pool train and drawing water system for small urban recreational water pollution control

摘要

A filtration-adsorption pool train (FAPT) and drawing water (DW) system was developed to control the small urban recreational water pollution at a senior hotel in Shanghai, China. The results from one year of operation indicated that the system had successfully achieved the water quality objectives: compared with the water quality before the treatment system worked, the average concentrations of SS, COD_(Mn), BOD5, NH3-N, TP and Chla were reduced by 79%, 39.5%, 45%, 36%, 44.3% and 70%, respectively, and DO and transparency were improved by 27% and 134%, respectively. The customers enjoyed a recreational, aesthetic and educational amenity along the ring pond. Therefore, it was conducted that the FAPT-DW system was an effective measure for small recreational waters, especially in urban areas with limited land resources.
