The findings indicate that the fixation rates of H2SO4 and FeSO4 modified zeolite with strain Q1 were 86.1% and 68.1% ，respectively，both of which were significantly greater than those observed with zeolite.The optimal adsorptiondurationwsdeterinedtobe4hours，duringhichtemodifiedzeolitedemonsratedtheosefectiveloadingofstrainQ1Furte more，the removal efficiencies of NH4+ -N in simulated domestic wastewater using H2SO4 and FeSO4 modified zeolite loaded with strain Q1 were recorded at 88.4% and 89.1% ，surpassing the removal rates achieved by free bacteria and zeolite.
