The treatment technology on the wastewater containing dihydric phenol-contained from the coal chemical industry was summarized. The adsorption, emulsion liquid membrane, solvent extraction, incineration, phenolic condensation, chemical oxidation, steam phenol removal, ozone oxidation, advanced oxidation are compared respectively including their advantages, disadvantages and application prospect. Among them, the solvent extraction method was underlined through the selection of extractant and the analysis of influence factor. Besides, the research evolution and tendency of the treatment technology on the dihydric phenol-contained wastewater was further prospected especially. The multi-technology combination would be a hot spot.
