Abstract: Biochar shows a good application prospect in the field of organic pollution wastewater treatment due to such advantages of wide source of raw materials, large specific surface area, rich pore structure and easy regulation of surface functional groups and so on. However, the different raw materials, preparation methods and modification methods of biochar influence the physical and chemical properties of biochar to a large extent, thus showing different properties and action mechanisms for organic pollution wastewater treatment. Based on the structural characteristics of biochar, the preparation technology, modification methods, as well as the present situation and future development opportunities of biochar for organic pollution wastewater treatment are discussed in this paper.

Key words: biochar, functional modification, wastewater treatment, organic pollutant, adsorption, catalysis, degradation
