The invention relates to the field of bioremediation of rivers, and in particular relates to a composite microbial preparation for watershed bioremediation as well as a preparation method and application thereof. The microbial preparation comprises active ingredients including bacillus natto, candida utilis and rhodopseudomonas palustris which are mixed together in a volume fraction ratio of 1:1:1; the microbes for water treatment are combined with zeolite to prepare a comprehensive preparation for water treatment; the specific gravity of the obtained comprehensive preparation for water treatment is greater than that of water, so that the obtained comprehensive preparation for water treatment quickly sinks to the bottom of water and can not be washed away by water flow easily; the zeolite is used as a carrier for the microbes to grow, and can provide certain nutrition substances required by growth for the microbes while adsorbing pollutants, and the microbes attached to the zeolite perform decomposition and anabolism on the pollutants to ensure that the zeolite restores the adsorptive property, so that a virtuous cyclic process is formed. The microbial agent provided by the invention can adapt to fresh water and seawater environments at the same time, and has an effective bioremediation effect on watercourses of certain coastal cities, wherein the water quality of the watercourses has fresh water and seawater alternating conditions along with seasonal changes.
