Abstract

The invention discloses a chromium-containing wastewater treatment system. The chromium-containing wastewater treatment system comprises a pH adjusting pond, a filtering device, an anion resin exchange system, a water storage pond and a solid-liquid separation system; a water outlet of the anion resin exchange system is communicated with the water storage pond; a desorption solution outlet of the anion resin exchange system is communicated with a desorption solution storage pond; the desorption solution storage pond is communicated with an evaporation and concentration device. According to the chromium-containing wastewater treatment system, Cr6+ can be effectively separated, Cr6+ containing wastewater is evaporated and concentrated by using the evaporation and concentration device so as to obtain Na2CrO7 crystal substances, and the Na2CrO7 crystal substances are recycled. The chromium-containing wastewater treatment system has the advantages of simple structure, high treatment efficiency and perfect treatment effect.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a chromium-containing wastewater treatment system. Background technique [0002] The sources of electroplating wastewater are generally: (1) plating cleaning water; (2) waste electroplating solution; (3) other wastewater, including washing the floor of the workshop, scrubbing plate washing water, condensed water from ventilation equipment, and leakage from plating tanks. Or various tank liquids and drainages of "running, popping, dripping, and leaking" caused by improper operation and management; (4) Equipment cooling water, which has not been polluted except for the temperature rise during use. The water quality and quantity of electroplating wastewater are related to the process conditions of electroplating production, production load, operation management and water use methods and other factors. The water quality of electroplating wastewater is complex and its co...
