The invention discloses a sulfonylurea herbicide polluted water and soil remediation agent as well as a preparation method and application thereof, and relates to the technical field of pesticide pollution remediation materials in environmental protection. The preparation method specifically comprises the following steps: adding coffee residue powder into an aqueous solution containing zinc chloride and ferric chloride hexahydrate, stirring and separating, drying a cured product, loading generated micro-nano zero-valent iron on the surface of coffee residue biochar activated by zinc chloride through a carbon thermal reduction method, and cooling to obtain the sulfonylurea herbicide polluted water and soil remediation agent. According to the invention, the problems that the biochar is easy to saturate during adsorption, the herbicide is easy to release after desorption and the herbicide cannot be thoroughly degraded can be solved, and the problems that micro-nano zero-valent iron is easy ...
