Heavy metal waste liquid treatment process

Abstract

The invention relates to the technical field of an industrial waste liquid treatment process, in particular to a heavy metal waste liquid treatment process. The heavy metal waste liquid treatment process comprises the following steps: heavy metal waste liquid is introduced into a filtering box and large particles in the metal waste liquid are filtered through the filtering box; the filtering box is arranged above waste liquid treatment equipment, and the filtering box and the waste liquid treatment equipment are connected through an electromagnetic disk; the filtered waste liquid is introducedinto the waste liquid treatment equipment; two electromagnetic disks are symmetrically arranged on the inclined surface of a supporting sleeve of the waste liquid treatment equipment; the lower end face of each electromagnetic disk is fixedly connected with the upper end of an iron rod, a net bag is arranged at the lower end of the iron rod and the lower end of the iron rod extends into a cavityof the waste liquid treatment equipment; when the waste liquid treatment equipment adjusts the position of a filtering structure, the net bag is dismantled in the process of the dismantling the filtering structure, and performing unified cleaning at the same time so as to improve the efficiency of the waste liquid treatment equipment. By the heavy metal waste liquid treatment process, heavy metalparticles can be efficiently eliminated.

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
