The invention provides a resourceful treatment process of tar residue. The resourceful treatment process is characterized in that demulsification dehydration, solvent extraction and centrifugal separation are taken as the core, distillate oil, obtained at the temperature of 200-230 DEG C, of coal tar is used as a main extracting agent, a small amount of crude benzene and industrial naphthalene areadded so as to form a composite extracting agent, and the proportion of all the components used in the process is as follows: 90-95wt/% of the distillate oil, obtained at the temperature of 200-230 DEG C, of the coal tar, 4.1-9.7wt/% of the crude benzene and 0.3-0.9wt/% of the industrial naphthalene; a technology of combining heat extraction and centrifugation is adopted under the conditions thatthe temperature of the demulsification dehydration is 35-55 DEG C, extraction temperature is 55-60DEG C, the pressure is 101.325kPa, the pump circulating flow rate is 15-20m<3>/h, the extraction timeis 3-4h, the centrifuge rotating speed is 2500-3000r/min, and the like, so that the recovery rate of tar in the tar residue reaches up to 95% or above. The resourceful treatment process is verified to be capable of well adapting to the raw material tar residue with water content of 20-60% in the aspect of raw material adaptability; the extracting agent used in the process does not need to be recovered after oil-water-residue separation is finished, can be directly used as an oil product component in the oil so as to be stored and utilized, and does not need to be recycled, so that the separation link is simplified, waste is avoided, and energy is saved; the resourceful treatment process effectively solves the problems of the tar residue in the aspects of energy utilization and environment-friendly treatment.
