description	The invention relates to the technical field of environmental pollution remediation, and discloses modified nano zero-valent iron as well as a preparation method and application thereof. The modified nano zero-valent iron is nano zero-valent iron modified by a biological surfactant and is prepared from the following components: a sophora japonica leaf extracting solution, the biological surfactant and mine wastewater. The locust tree leaves are a renewable environment-friendly material, the iron-containing mine wastewater can provide sufficient iron sources and reduce environmental pollution, and the biosurfactant is low in raw material cost, good in biological activity, efficient, green and free of secondary pollution. The invention provides a low-cost and environment-friendly nano zero-valent iron synthesis method, the nano zero-valent iron is modified by adding the biological surfactant, the reduction effect can be achieved, nano particles can be protected from being oxidized and agglomerated, and therefor
