The invention belongs to the technical field of coal seam water injection dust suppression, and particularly relates to a biological reaming and moistening agent and a preparation method and application thereof. The biological pore-enlarging and moistening agent is prepared from the following components: acid-producing flora, nutrient substances, a biological surfactant and ethanol wastewater. Acetic flora is enriched from waste vinegar culture in the vinegar brewing industry under a non-sterile condition and mixed with a culture solution containing ethanol wastewater to prepare a biological pore-enlarging and moistening agent, and the biological pore-enlarging and moistening agent is injected into a coal seam water injection hole, so that the acetic flora is attached to the surface of a coal seam to oxidize ethanol to generate a corrosive substance acetic acid so as to expand coal seam pores. The acetic bacteria culture solution containing the ethanol wastewater is used for treatment, so that the problems th
