Abstract

The invention discloses a treatment system for acid copper wastewater. The treatment system comprises a wastewater pretreatment system, a metal recovery system, a first-grade treatment system, a second-grade treatment system and a conveying system which are in successive connection through pipelines; the wastewater pretreatment system comprises an acid copper wastewater collection pool, an original water pump and a filter which successively communicate through pipelines; the metal recovery system comprises a plurality of copper adsorption devices which are connected in series through pipelines; the first-grade treatment system comprises a first-grade fine filtration device, an ultrafiltration device and an intermediate water tank which successively communicate through pipelines; the second-grade treatment system comprises a booster pump, a carbon filter device, a second-grade fine filtration device, a high-pressure pump and a membrane separation device which successively communicate through pipelines; and the conveying system comprises a reuse water tank and a conveying pump. The treatment system for the acid copper wastewater provided by the invention has the advantages of good treatment effect and good metal recovery rate.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a treatment system for acid copper waste water. Background technique [0002] Due to the variety of electroplating processes, the composition of the wastewater produced is also very complex. Among them, heavy metal wastewater is a category of wastewater that accounts for a particularly large proportion. If it is not treated properly, it will cause serious environmental pollution. At present, the heavy metal recovery and wastewater reuse system of electroplating wastewater mainly include: ion exchange method, full membrane treatment method and comprehensive wastewater chemical sedimentation and membrane treatment method. These methods generally have low water quality for wastewater reuse treatment. Or the problem of low content of heavy metal ions after recovery, which does not meet the standards for industrial wastewater treatment and is not environmentally friendly. Conten...
