This utility model belongs to the field of coal chemical wastewater pretreatment technology, and discloses a resource substance recovery system for coal chemical wastewater, including an adsorption separation system, an adsorption material regeneration system, and a recovery and regeneration system. The adsorption separation system is used to adsorb and separate resource substances in the wastewater to be treated using adsorption materials. The resource substances in the wastewater to be treated include oils and phenols. The adsorption material regeneration system is used to regenerate the adsorption material using a regeneration solution. The recovery and regeneration system is used to regenerate the regeneration solution and separate and recover the adsorbed resource substances. This utility model achieves efficient separation of oils and phenols by filling the adsorption separation device with adsorption material. The adsorption material regeneration system provides a regeneration solution to the adsorption separation device to achieve elution and regeneration of the adsorption material, thereby realizing the recycling of the adsorption material and effectively reducing the recycling and treatment cost.
