Abstract

A medium material for removing phenol contamination from groundwater, a method of producing the same, and use of the same id disclosed. In at least some embodiments, the medium material is a granular material which has an average particle diameter of 0.5-1.5 cm and is formed from a bacteria-entrapping solution, a manganese sand filter material, modified bentonite, and biochar at a mass ratio of 1:0.2-0.4:0.2-0.4:0.1-0.2 by a series of processes including strain culturing, catalysis, mixing, solidification, and the like. The medium material can remove phenol from groundwater, is a safe and environment-friendly material, has a long service life, and/or achieves waste treatment with waste.
