Beschreibung
Zusammenfassung:	The present invention provides a biochar-based three-dimensional composite material and a method for remediating high-concentration chromium-contaminated soil. The biochar-based three-dimensional composite material is obtained by loading, oxidizing, and polymerizing biochar and m-phenylenediamine. The biochar-based three-dimensional composite material and a domesticated dominant strain are used together for remediating chromium-contaminated soil. According to the method, the defects that the microbial remediation period is long, the environmental adaptability is poor, physical adsorption of common biochar cannot fundamentally eliminate contaminants, and the like can be overcome. The synergistic effect of the two can enhance the actual remediation effect on the contaminated soil and shorten the remediation operation period. The biochar-based three-dimensional composite material of the present invention is simple in the preparation process, low in cost, environmentally friendly, free of secondary contamination,
