摘要

电镀含铬废水中重金属铬以Cr~(6+)和Cr~(3+)2种形式存在,其中Cr~(6+)的毒性最大,含量达60 g/L,传统化学还原加入亚硫酸盐的方法,因加入亚硫酸盐的量大,生成大量悬浮物使废液形成浆糊状,故无法进行固液分离,且不能保证Cr~(6+)的全部氧化,如果进行数倍的稀释将会产生大量废水。采用综合治理的方法对废水中的Cr~(6+)进行去除,达到了以废治废的目的,同时确保废水中总铬含量达标。
        Heavy metal chromium in chrome-containing wastewater is present in the form of Cr~(6+) and Cr~(3+), of which Cr~(6+) is the most toxic and has a content of 60 g/L. In traditional chemical reduction methods with sulfites, because more sulfites is added,a large number of suspensions are generated, solids and liquids cannot be separated,and Cr~(6+) cannot be oxidized completely, and several times dilution will produce a large amount of wastewater. The comprehensive treatment method was used to remove Cr~(6+) in the waste water which ensured that the total chromium content in the wastewater is up to the standard.
