Abstract：Aimingatthemanagementofurban blackandsmellwater bodies，thispaperoptimizes thecombinationof biofilmmethod，solaraerationmethodandecologicalfloatingbedmethodwiththewaterdisolvedoxygenmonitoringsystemto developanautomaticon-offoxygen-richcompositeecologicalfloatingbedpurificationdevice.Experimentalresultsshowthatthe removal rates of TPby the composite device，combined device and ecological floating bed are 7 9 . 7 3 % ， 7 0 . 8 3 % and 45.95 % ，respectively，the removal rates of TN are 9 0 . 0 0 % ， 7 9 . 6 6 % and 4 8 . 3 3 % ，respectively，the removal ratesofNH -Nare 9 3 . 6 2 % （20 9 2 . 5 5 % and 4 4 . 6 8 % ，respectively，and the removal rates of COD are 7 4 . 6 % ， 6 6 . 1 3 % and 4 6 . 3 7 % ，respectively. Compared with M n the combined device，the combined device has significant removal effects of TN and COD and shows slight advantages in the removal of TP and NH -N.Theexperimental results confirm that the purification effct of the composite ecological floating bed purificatiodeviceonblackandsmellwaterbodiesisbeterimprovedthanthatofsingleandsimplecombinationpurfcation devices.Itisworthpromotingandaplyinginurbanriverwaterenvironmentmanagementandrestorationprojectstoachievethe goal of saving energy and efficiently restoring.
