Abstract

The invention discloses a liquid-phase ion exchange device which comprises a reactor I and a reactor II. The reactor I is connected with a regeneration reactor II, a regeneration reactor I is connected with the regeneration reactor II, the regeneration reactor II is additionally connected with an alkali liquor tank, and the regeneration reactor I is additionally connected with a resin tank. Compared with a traditional chemical precipitation method, the liquid-phase ion exchange device is simple in structure, scientific and reasonable in design, and the usage effect is not affected while parts are decreased. In addition, due to the fact that liquid-phase ions are introduced, the chromium content in wastewater is greatly decreased, and meanwhile the sludge quantity can be obviously decreased.

Description

technical field [0001] This specification belongs to the field of environmental protection, and specifically relates to a liquid-phase ion exchange device. Background technique [0002] Chromium-containing wastewater mainly comes from industrial pollution, especially the electroplating industry. Electroplating is a process that uses electrochemical methods to decorate, protect and obtain certain new properties on metal and non-metal surfaces. In the electroplating process, in order to ensure the quality of electroplating products, make the metal coating have a smooth and good appearance and be firmly combined with the plated parts, the dirt (oil, rust, scale, etc.) on the surface of the plated parts must be thoroughly cleaned before plating. Clean up and clean the adhesion solution on the surface of the plated parts after plating. Therefore, the sources of electroplating chromium-containing wastewater are generally chromium-containing wastewater from plating parts cleaning...
