Problems solved by technology

[0003] In the prior art, when flocculants are used to react and remove metal ions in wastewater, the use of flocculants is relatively concentrated, so that it cannot be fully mixed and contacted with wastewater, and the contact area between flocculants and wastewater cannot be increased. The removal efficiency of heavy metals is not very high. Therefore, we propose a zero-discharge recycling treatment device and process for heavy metal wastewater from electroplating.

Abstract

The invention discloses a zero-discharge recycling treatment device and process for electroplating heavy metal wastewater, and relates to the technical field of electroplating heavy metal wastewater zero-discharge recycling treatment. The device comprises a collecting unit, a treatment unit is arranged at the top of the collecting unit, an aqueous solution mixing unit is arranged at the upper end of the exterior of the treatment unit, a conveying unit is arranged at the top of the treatment unit, a filtering unit is arranged beside the treatment unit, and the filtering unit is connected with the conveying unit. Through cooperation of the collecting unit, the treatment unit, the filtering unit, the aqueous solution mixing unit and the conveying unit, a used flocculating agent can be fully mixed and contacted with wastewater, and the contact area of the flocculating agent and the wastewater is increased, so that the removal efficiency of heavy metals in the wastewater is improved, zero discharge of electroplating heavy metal wastewater is facilitated, and recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of zero-discharge and reuse treatment of electroplating heavy metal wastewater, in particular to a zero-discharge and reuse treatment device and process for electroplating heavy metal wastewater. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. [0003] In the prior art, when flocculants are used to react and remove metal ions in wastewater, the use of flocculants is relatively concentrated, so that it cannot be fully mixed and contacted with wastewater, and the contact area bet...
