钢渣处理含铬废水的研究

A Resarch into Treating Wastewater Which Contains Chromium with Slag

用钢渣处理含铬废水 ,对处理各工艺参数进行了试验 ,结果表明 ,在废水pH值 2 5～ 12 ,Cr3 + 0～35 0mg/L ,按铬 /钢渣重量比为 1/35投加钢渣进行处理 ,铬去除率为 99% 。

Treating wastewater which contains chromium with wlag.We experimented on treating each technology parameter.As a reault,in wastewater pH=2.5～12,Cr 3+ 0～350mg/L,We added slag in the proportion of 1/35(Chromium/Slag),the rate of remove is 99%,the result can come up to drainage standards.
