Sewage treatment equipment for heavy metal ions

Abstract

Belonging to the field of sewage treatment equipment, the invention discloses sewage treatment equipment for heavy metal ions. The equipment comprises a treatment box, a filtering mechanism, a drainage mechanism, a drug supply reaction mechanism and a disinfection discharging mechanism. The treatment box is internally provided with a first partition board and a second partition board, the first partition board and the second partition board divide the internal space of the treatment box into a first cavity, a second cavity and a third cavity, the top of the treatment box is equipped with a water inlet port, the filtering mechanism includes a filter screen, a sewage disposal driving component, a sewage draining component and a driving component, the filter screen is horizontally arranged inthe first cavity in a circular ring, the side wall of the second partition plate is provided with a water control component, and the outer side wall of the treatment box is equipped with a condensingwater outlet pipe. While reaching sewage filtration, the equipment provided by the invention does not cause adhesion of sludge impurities and the like in sewage to the inner wall of the treatment box, and utilizes multiple treatment procedures to improve the sewage treatment efficiency and effect, also can separate heavy metals from sewage, and improves the recovery rate of heavy metals.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to sewage treatment equipment for heavy metal ions. Background technique [0002] With the development of modern society, the amount of sewage containing heavy metal ions is increasing. Because heavy metal ions are difficult to degrade under natural conditions, they will not only pollute water sources, soil and other environments, but also cause pollution through the enrichment of the food chain. Finally, it enters the human body, thereby causing harm to human health. Therefore, it is particularly important to treat sewage containing heavy metal ions. The existing equipment for treating heavy metal pollution generally has poor purification capabilities, single purification methods, and cannot process the generated sludge. deal with the problem. [0003] Patent CN202657980U discloses a sewage treatment device, which includes a sewage treatment tank, a sewage storage tank, a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sewage treatment equipment for heavy metal ions to solve the problem of low sewage treatment efficiency and low recovery efficiency of heavy metal ions in the prior art, and it is easy to cause sludge impurities in sewage to adhere to when sewage is filtered. On the inner wall of the sewage treatment tank, it affects the treatment effect of sewage and brings inconvenience to the cleaning work of workers.
