The present application relates to the technical field of chlorine-containing electronic wastewater treatment, and particularly relates to an electrolytic adsorption device and application thereof.The present application provides an electrolytic adsorption device, comprising anodes and cathodes arranged alternately and in parallel; the anode comprises an anode substrate and an anode material coated on the surface of the anode substrate; the anode substrate comprises a titanium foil and a titanium dioxide nanotube layer on the surface of the titanium foil, and the titanium dioxide nanotube layer is a three-dimensional array structure; the anode material is a composite material of SnO2, Sb and RuO2; the cathode comprises a cathode substrate and a cathode material coated on the surface of the cathode substrate, and the cathode material is a mixture comprising a carbon-based material and ferroferric oxide. The electrolytic adsorption device has low cost, does not have strict requirements on the treatment conditions of chlorine-containing electronic wastewater, and can effectively remove COD and / or has a relatively high heavy metal (Cu 2+ ) recovery rate.

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.
