Heavy metal ion sewage treatment equipment

Abstract

The invention relates to the field of sewage treatment equipment, in particular to heavy metal ion sewage treatment equipment. The equipment comprises a sludge treatment mechanism, a disinfection mechanism and an exhaust gas treatment mechanism, wherein the sludge treatment mechanism comprises a pesticide spray assembly, a sedimentation cabinet and a discharging assembly, the discharging assemblycomprises a material transferring plate, a material pushing member and two sliding bars, the two sliding bars are horizontally arranged, and the material transferring plate is slidingly matched with the sliding bars. The equipment of the invention has the beneficial effects that the sludge treatment mechanism can automatically eliminate sludge generated in sewage and can process heavy metals in the sludge, with the exhaust gas treatment mechanism, moisture generated after heating can be recovered and treated, and a floc processing assembly can process flocs produced after precipitation to prevent heavy metal or sundries from sticking to side walls of an evaporation cabinet and affecting cleaning operation of workers on the evaporation cabinet.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to heavy metal ion sewage treatment equipment. 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] The patent No. CN106219914A is an invention patent for a sludge treatment device, including a treatment tower, a sludge inlet ...

AI Technical Summary

Problems solved by technology

[0004] Although this invention can filter the sludge, the heavy metals in the sludge inside the treatment tower cannot be removed, resulting in insufficient removal of heavy metal ions; this patent directly discharges the water vapor through the exhaust port, and cannot treat the discharged water. The waste of water resources is caused by the recycling of gas; after the sewage evaporates, heavy metals or other dirt will be left on the inner wall of the heating box, which will affect the heating efficiency of the heating device in the invention, and at the same time bring great harm to the cleaning work of the workers. influences
