Description

Technical Field

[0001] The utility model relates to the technical field of new material processing, in particular to a processing device for liquid containing heavy metals. Background Art

[0002] The sources of electroplating wastewater are generally: plated cleaning water, waste plating liquid and other wastewater, including water from washing the workshop floor, washing plate water, condensed water from ventilation equipment, and various tank liquids and drainage caused by leakage of plating tanks or improper operation and management; equipment cooling water, which is not polluted except for the increase in temperature during use. The water quality and water volume of electroplating wastewater are related to factors such as the process conditions, production load, operation management and water use of electroplating production. The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions and cyanide such as chromium, cadmium, nickel, copper, zinc, gold, silver, etc., some of which are highly toxic substances that are carcinogenic, teratogenic and mutagenic.

[0003] When treating electroplating waste liquid, we will use electroplating waste liquid treatment equipment. The current heavy metal liquid treatment equipment is too simple in treating waste liquid and cannot effectively treat the heavy metals contained in the waste liquid, so that the waste liquid still contains a large amount of heavy metal substances, which will pollute the environment after being discharged, and can no longer meet the needs of users.

[0004] To this end, we propose a new type of processing device. Utility Model Content
