Research on Deep Treatment and Recycle Technology of Acidic Steel Rolling Wastewater
This paper studies the deep treatment process of acidic wastewater from steel rolling,which uses two-stage electrosorption treatment,the removal of chloride and fer-rous ions is good,the conductivity of the produced water can be reduced to less than 500 uS/cm,the desalination rate reaches more than 97%,and the comprehensive water yield reaches more than 80%.After the alkali neutralization of produced water,the water quality meets the recycled water quality standard of WISCO,and can be reused in the pipeline net-work with good emission reduction effect,which is of great significance to improve the com-petitiveness of products in the market and the level of clean production of the process.
