Zeolite composite material for in-situ remediation of black and odorous water body and improvement of bottom mud structure

The invention relates to the technical field of urban water pollution ecological restoration, in particular to a zeolite composite material for in-situ restoration of a black and odorous water body and improvement of a bottom mud structure. According to the zeolite-loaded iron-manganese bimetallic composite material, natural zeolite powder serves as a carrier, ferric trichloride and potassium permanganate serve as a Fe source and a Mn source for modification, and the composite material is obtained through the processes of centrifugation, washing, drying, smashing and calcination. The composite material is applied to black and odorous water bodies and bottom mud, pollutants in overlying water can be quickly and effectively removed, meanwhile, the oxidation-reduction potential (ORP) and dissolved oxygen (DO) are improved through the microbattery principle, the living environment of indigenous microorganisms is improved, the indigenous microorganisms in the water bodies are activated, the integrity of ecological
