This study developed mycelial biochar composites, BQH-AN and BQH-MV, with stable physicochemical properties and significantly improved adsorption capabilities through microbial modification. The results showed that the specific surface area and porosity of BQH-AN (3547.47 m2 g−1 and 2.37 cm3 g−1) and BQH-MV (3205.59 m2 g−1 and 2.46 cm3 g−1) were significantly higher than those of biochar BQH (2641.31 m2 g−1 and 1.81 cm3 g−1), which was produced without microbial treatment. In adsorption experiments using rhodamine B (RhB), tetracycline hydrochloride (TC), and Cr (VI), BQH-AN showed maximum adsorption capacities of 1450.79 mg g−1 for RhB, 1608.43 mg g−1 for TC, and 744.15 mg g−1 for Cr(VI). BQH-MV showed similarly strong performance, with 1329.85 mg g−1 for RhB, 1526.46 mg g−1 for TC, and 752.27 mg g−1 for Cr(VI). These values were not only higher than those of BQH but also outperformed most other biochar adsorbents. Additionally, after five reuse cycles, the pollutant removal efficiency of the mycelial biochar composites remained above 69%, demonstrating excellent regenerative ability. This study not only produced biochar with superior adsorption properties but also highlighted microbial modification as an effective way to enhance lignocellulosic biochar performance, paving the way for further biomass development.
