Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a pyrophosphate treatment and dosing device for sanitary ware electroplating wastewater. Background Art

[0002] Bathroom literally means hygiene and bathing. Bathroom is commonly known as the toilet which is mainly used for bathing. It is the space and supplies for residents' daily hygiene activities such as defecation, bathing and washing.

[0003] Currently, the water-passing parts for bathing and washing face, such as shower heads, used in bathrooms are all bathroom parts, which can facilitate people to use hot or cold water.

[0004] When bathroom fittings are being made, they need to be electroplated to ensure their overall collision strength and rust resistance. During electroplating, the plating metal or other insoluble materials serve as the anode, and the workpiece to be plated serves as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the plating layer uniform and firm, a solution containing the plating metal cations is required as the electroplating solution to keep the concentration of the plating metal cations unchanged.

[0005] During electroplating, pyrophosphate is produced. In a dilute aqueous solution, phosphate exists in four forms. In a strong alkaline environment, phosphate ions (PO4 3- ) will be more, and in a weakly alkaline environment, hydrogen phosphate ions (HPO4 2- ) is more, in a weak acid environment, dihydrogen phosphate ions (H2PO4 - ) is more common, while in a strong acid environment, water-soluble phosphoric acid (H3PO4) is the main form.

[0006] At present, when treating electroplating wastewater, the wastewater is generally filtered and sent to a wastewater pool. Then, chemicals are added to the wastewater pool to make it contact and react with the substances contained in the wastewater, thereby causing sedimentation, which is convenient for waste recycling. However, when adding chemicals, most workers use hand-held cartridges to pour the chemicals. However, if the cartridge is large and contains a lot of chemicals, it will not only be time-consuming and laborious for the workers to pour the chemicals, but some wastewater pools are too high and the workers cannot perform the pouring work normally.
