Description

Technical Field

[0001] The utility model relates to the field related to electroplating wastewater, in particular to a copper electroplating wastewater treatment device. Background Art

[0002] The wastewater output of the electroplating industry is less than that of the papermaking, printing and dyeing, and chemical industries. However, due to the wide distribution of electroplating plants, the electroplating wastewater contains many types of harmful substances. Therefore, the treatment of electroplating wastewater is very important. Electroplating wastewater mainly contains heavy metal ions such as chromium, zinc, copper, lead, nickel, and carcinogenic cyanide. If these substances are directly discharged into nature, on the one hand, they will cause great pollution to the environment and seriously threaten the life safety of animals and plants. On the other hand, the heavy metal ions in electroplating wastewater can be reused after recycling, and direct discharge will cause a waste of resources.

[0005] After flocs are produced in wastewater treatment, this structure discharges the sunken flocs and the upper clean water through the discharge port. It is impossible to separate the clean water and flocs during discharge. Instead, the uniformly discharged water and floc mixture needs to be transported to the separation equipment for separation and recovery. This is more troublesome, less flexible, and the structure needs to be strengthened. Utility Model Content
