Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a deep zinc removal treatment device for acid mine wastewater. Background Art

[0002] In the acidic mine wastewater, sulfide ores and pyrrhotite undergo a series of physical and chemical reactions such as leaching, oxidation, and hydrolysis under the action of air, water, and microorganisms, forming yellow-brown acidic wastewater containing a large amount of heavy metal ions and sulfate anions, including zinc ions. This wastewater has a serious impact on the environment. The traditional zinc removal treatment process usually involves adding alkaline substances through a neutralization reaction.

[0003] The existing lack of equipment for deep treatment of zinc in wastewater results in the presence of impurities during subsequent purification, resulting in continuous discharge of low-concentration waste liquid and intermittent discharge of high-concentration waste liquid during operation. The waste liquid has not been processed and collected, causing water pollution, destroying the natural environment, and endangering human health. It is highly harmful. Therefore, we propose a deep zinc removal treatment equipment for acidic mine wastewater to solve the above problems. Utility Model Content
