Abstract：At present，thereare problemswith environmentalpolltionandinsufficientresourceutilizationof irontailings， as well as dificulties inthe treatment and disposal of biogas slury in livestockand poultry farms.Thecollaborative treatment mode of‘iron tailings + biogas slurry”is designed based on microbial enhancement.In this mode，the organic mater and trace elements rich in biogas slury provide nutritional sources for microrganisms and plants; Combining beneficial microorganismssuch as nitrogen fixing bacteria，phosphorus solubilizing and potasium solubilizing bacteria， and silicon releasing bacteria with pioneer plants，ecological restoration is cariedout through biological enhancement technology; tailingssandserves asacarier toadsorb nitrogenandphosphorus from biogas slurry，promoting soilstructure stabilityandnaturalvegetationsuccession，ultimatelyformingaself-sustaining ecosystem.This model has theadvantagesof adapting tolocalconditions，grenandlow-arbo，andsolidwasteresourceutilzation，especiallinlinewiththeidustrial characteristics of Hebei province's equal emphasis on stel and agriculture，itis expected to provide technical support for thetreatmentofsolid waste intailings areas，andhelpachievethegoals ofa“zero-wastecityand green mineconstruction.
