The invention relates to a refined anthracene and carbazole purification method. The purification method comprises the following steps: crystallizing and separating crude anthracene in a solvent I by adopting a solvent extraction and crystallization process, wherein crystal substances are semi-refined anthracene and the solution is a crude anthracene mother liquid; dissolving the semi-refined anthracene in a solvent II, ending heating and dropwise adding a solvent III for precipitation, separating the crystal substances to obtain the refined anthracene of which the concentration is higher than 95%; adding a solvent IV into the filtrate for crystallization to obtain the carbazole and solvent filtrate, separating the solvent filtrate to obtain the solvents II, III and IV which are recyclable, dissolving the carbazole into the solvent I for recrystallization, and separating final carbazole solids to obtain the carbazole of which the concentration is higher than 96%, wherein the crude anthracene mother solution and the carbazole filtrate can be used for replacing the solvent I for the crystallization of the semi-refined anthracene so as to realize recycling, and after saturation, the crude anthracene mother liquid and the carbazole filtrate can be used as fuel oil. The method is simple to operate, high in separation efficiency and free of generation of wastes during the whole reaction process.
