Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating wastewater, and in particular relates to an electroplating wastewater electrolysis device. Background Art

[0002] Electroplating wastewater is wastewater containing harmful substances generated during the electroplating process. It needs to be specially treated to reduce harm to the environment. The main sources of electroplating wastewater are plated cleaning water, waste plating solution and other wastewater in the production process, such as water for washing the workshop floor, plate washing water and ventilation equipment condensate, etc. According to the main pollutants contained, electroplating wastewater is usually divided into three categories: chromium-containing wastewater, cyanide-containing wastewater and other comprehensive wastewater (such as copper, nickel, zinc, etc.). The treatment and reuse of electroplating wastewater is of great significance for saving water resources and protecting the environment. Through the above-mentioned various treatment technologies, not only can harmful substances be removed, but also some valuable metal elements can be recovered to achieve the recycling of resources. If untreated or inadequately treated electroplating wastewater is discharged directly, it will cause serious pollution to the water body and ecological environment, affecting human health and ecological balance.

[0003] The existing authorized public number is CN204079552U, which discloses a sewage electrolysis device, comprising a plate (1) and an electrolysis box (2), wherein the plate comprises a cathode plate (3) and an anode plate (4), wherein the cathode plate (3) and the anode plate (4) are staggered and laminated in the electrolysis box (2), wherein a liquid outlet (5) is arranged on the side wall of the electrolysis box, wherein the opening of the electrolysis box (2) is connected to a gas treatment device (6), wherein the liquid outlet (5) is provided with a filtering device (7), wherein a pH indicator (8) is provided on the electrolysis box, and wherein a sight glass (9) is provided at the opening of the electrolysis box (2). The utility model has the advantages of simple structure and that the treated water meets production requirements. However, the above-mentioned sewage electrolysis device does not have a device for absorbing the waste gas generated during the sewage electrolysis process. When sewage, especially electroplating sewage, is electrolyzed, a large amount of waste gas carrying harmful substances will be generated. If these waste gases are discharged directly without treatment, they will cause harm to the health of on-site operators and will also pollute the surrounding ambient air. Therefore, it is necessary to provide an electroplating sewage electrolysis device to solve the above problems. Utility Model Content
