The invention discloses a method for separating biomass components through a ternary system, and relates to the technical field of biomass separation. The method comprises the following steps: cooking and separating a biomass raw material by using cooking liquor consisting of organic acid, small molecular aromatic nucleophilic organic matters and hydrogen peroxide to obtain solid matters and black liquor, washing and screening the solid matters to obtain paper pulp, and extracting lignin and/or hemicellulose by using the black liquor; the method has the advantages that residual lignin and compounds of other chromophoric groups in the paper pulp are reduced, the high-whiteness paper pulp with excellent performance is obtained, an additional bleaching process is not needed, hemicellulose saccharide and polyphenol lignin can be obtained, and the method has important significance in realizing high value and industrialization of biomass resource utilization. 本发明公开三元体系分离生物质组分的方法,涉及生物质分离技术领域；利用有机酸、小分子芳香族亲核有机物和过氧化氢组成
