Device for recovering chromic acid from high-concentration chromium-containing wastewater in electroplating centralized control area through resin adsorption

The utility model belongs to the field of sewage treatment, and relates to a device for recovering chromic acid from high-concentration chromium-containing wastewater in an electroplating centralized control area through resin adsorption, which is characterized by comprising a stock solution pool (1), a pressure pump (2), a liquid injection port (3), a first resin adsorption cylinder (4), first negative resin (5), a liquid outlet hole (6), a first liquid outlet pipeline (7), a first buffer pool (8) and a first controllable valve (9), stoste is stored in the stoste pool (1), the stoste pool (1) is communicated to a liquid injection port (3) at the bottom of the first resin adsorption cylinder (4) through a pressure pump (2) and a pipeline, and a screened negative fat absorber (5) is arranged in the first resin adsorption cylinder (4). According to the device and the method, the chromium-containing wastewater treatment efficiency is improved, the environmental pollution risk is reduced, and the high-concentrati
