The invention relates to the technical field of wastewater treatment, and discloses a preparation method of an activated carbon-containing adsorbent material and its application in wastewater treatment. The invention obtains the activated carbon-containing adsorbent material by adding modified phenolic resin, activated carbon and sulfonated chitosan into a twin-screw extruder for melt extrusion. The phenolic resin has a high phenolic hydroxyl content and strong hydrophilicity, and exhibits good adsorption effect on heavy metal ions such as chromium and lead ions in wastewater. The coordination and hydrogen bonding of amino groups in the phenolic resin enhance its adsorption capacity for heavy metals to achieve synergistic flocculation. Sulfonic acid groups undergo complexation with heavy metal ions to form micro-flocs, which precipitate via charge neutralization with quaternary ammonium groups, effectively removing heavy metals and achieving flocculation. Meanwhile, chitosan is a natural antibacterial agent, which forms an antibacterial system together with quaternary ammonium and sulfonic acid groups for synergistic antibacterial effect.
