Microbial preparation for conditioning aquaculture water environment and preparation process thereof

The invention relates to the technical field of aquaculture, and discloses a microbial preparation for conditioning an aquaculture water environment and a preparation process of the microbial preparation. The invention discloses a microbial preparation with a capsule structure. The microbial preparation is prepared from the following raw materials: gelatin microspheres coated with mixed bacterial powder, sodium thiosulfate, ferric sulfate and nano titanium dioxide, when the microbial preparation is put into a water body, the gelatin is hydrolyzed, and sodium thiosulfate and ferric sulfate which are released quickly decompose nitrite in the water body through a reduction effect; after a period of time, gelatin shells of the gelatin microspheres are hydrolyzed to release mixed bacterial powder, at the moment, sodium thiosulfate and ferric sulfate in the water body are fully acted, the content of nitrite in the water body is low, the water quality is good, and a good environment is provided for initial growth of
