Abstract

The high-alkalinity wastewater generated from aluminum factory is treated by ultrafiltration-electrodialysis integrated technology. Firstly, an ultrafiltration device is used for pretreatment of alkaline wastewater to make permeation solution meet the influent requirement of electrodialyzer and enrich the aluminum therein; secondly, the ultrafiltration permeation solution is adjusted by electrodialysis technology to determine optimum technological parameter, and finally to make purified water reach the process water standard, and moreover, the alkali content in effluent water at concentration end is enriched to the recycled concentration, and to attain the purpose of resource recycle.
