AI Technical Summary

Technical Problem

Existing technologies for treating industrial wastewater containing heavy metal ions suffer from problems such as high reagent consumption, easy generation of sludge for secondary pollution, and unstable treatment effects.

Method used

The pretreatment unit uses a stirring tank for chemical dosing and stirring, combined with the filter screen of the adsorption unit and the adsorption filter element in the filter box for multi-stage treatment. The water quality is monitored in real time by a water quality detection device in the conduit, and the control valve determines whether the wastewater is returned to the adsorption unit for secondary treatment based on the detection results.

Benefits of technology

It achieves efficient mixing of reagents and multi-stage filtration of heavy metal ions, ensuring stable and compliant effluent quality, avoiding direct discharge of substandard wastewater, and solving the problem of unstable treatment effect in traditional methods.

Abstract

The utility model relates to the technical field of industrial wastewater purification, and discloses a heavy metal ion-containing industrial wastewater purification treatment device which comprises a pretreatment mechanism and a purification mechanism, and the purification mechanism is fixedly connected to the bottom of the pretreatment mechanism. According to the heavy metal ion-containing industrial wastewater purification treatment device, chemicals are added and stirred through the stirring tank of the pretreatment mechanism, so that the chemicals and wastewater can be fully mixed and reacted, and the heavy metal ion concentration is preliminarily reduced; a filter screen of the adsorption unit and an adsorption filter element in a filter box further filter and adsorb residual heavy metal ions to form a multi-stage treatment system, the water quality can be monitored in real time through a water quality detection device in a guide pipe, and if the water quality is detected to be unqualified, a control valve closes a discharge pipe and opens a return pipe, so that the wastewater flows back to the adsorption unit for secondary treatment; direct discharge of unqualified wastewater is avoided, the water quality of final effluent is ensured to be stable and reach the standard through the circulation mechanism, and the problem that the treatment effect of a traditional method is unstable is solved.
