A heavy metal waste liquid treatment process

Abstract

The invention relates to the technical field of industrial waste liquid treatment technology, specifically a heavy metal waste liquid treatment process, which includes the following steps: passing the heavy metal waste liquid into a filter box, and filtering the large particles in the metal waste liquid through the filter box Filter; the filter box is installed above the waste liquid treatment equipment, and the filter box and the waste liquid treatment equipment are connected by an electromagnet; the filtered waste liquid is passed into the waste liquid treatment equipment; in the waste liquid treatment Two electromagnet disks are installed symmetrically on the slope of the support sleeve of the equipment; the lower end of the electromagnet disk is fixedly connected to the upper end of the iron rod, the lower end of the iron rod is installed with a net bag, and the lower end of the iron rod extends into the cavity of the waste liquid treatment equipment; when the waste liquid When the treatment equipment adjusts the position of the filter structure, the net bag is also removed during the process of dismantling the filter structure, and the cleaning is performed at the same time, thereby improving the efficiency of the waste liquid treatment equipment; the invention realizes the efficient removal of heavy metal particles.

Description

technical field [0001] The invention relates to the technical field of industrial waste liquid treatment technology, in particular to a heavy metal waste liquid treatment process. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by metals or their compounds with a density above 5. It is mainly caused by human factors such as mining, waste gas discharge, sewage irrigation and the use of heavy metal products. With the rapid development of society, people pay more attention to the environment. It is particularly important to treat heavy metals in waste liquid through the heavy metal waste liquid treatment system for industrial production, which reduces the impact of industrial production on the environment. [0003] In the process of treating industrial waste liquid, a waste liquid treatment system is usually used. However, the filter equipment in the traditional heavy metal waste liquid treatment system for industrial production is n...

Problems solved by technology

[0003] In the process of treating industrial waste liquid, a waste liquid treatment system is usually used. However, the filter equipment in the traditional heavy metal waste liquid treatment system for industrial production is not easy to clean when filtering the larger waste residue in the heavy metal waste liquid. waste residue, and the equipment will be shut down for a long time when cleaning the waste residue, the operation flexibility is poor, and the anti-blocking performance is poor during use

At the same time, the large waste residue in the waste liquid will seriously affect the subsequent filtration process and seriously affect the overall efficiency of waste liquid treatment
