The technology of dominant bacteria was used on the saturated medium materials.The medium material adsorption properties of ammonia and the ammonia nitrogen degradation by microorganisms were investigated in situ.The results showed that the concentrations of ammonia nitrogen in an artificial eutrophicated water were decreased from 110 mg/L to 73.31 mg/L and 89.18 mg/L in zeolite and activated carbon filter after 360 h dynamic adsorption.These results suggested that the adsorption capacity of zeolite was hig...
