Feasibility and purification effect of nitrogen removal from severely eutrophic water by floating culture with celery,Chrysanthemum coronarium and garlic were investigated via static culture tests in aquarium.Experiments on absorption kinetics were performed by normal depletion method to study nitrogen uptake characteristics of three terrestrial vegetables.Results showed these vegetables were in good growth condition and relative growth of biomass were 121.24%~330.12%.Three vegetable floatingbed system puri...
