以炉渣为载体处理重金属废水的吸附研究

Study on Adsorption of Heavy Metal Wastewater by Slag as Carrier

通过对昆明危险废物处理处置中心高温焚烧车间的焚烧炉渣进行筛选、毒性浸出检测及预处理,将其用于处理重金属废水研究中。结果表明,经过预处理的炉渣对含砷、铬、锌的重金属有较好的吸附效果,粒径<10mm的炉渣,加入最佳比例为13.33%,对砷、铬、锌的去除率分别达到87.09%、99.31%和99.99%。

The screening and pretreatment of incineration slag in the high temperature incineration plant of Kun-ming treatment center and dangerous waste was used in the treatment of heavy metal wastewater.The results showed that the pretreated slag had good adsorption effect on the heavy metals containing arsenic,chromium and zinc,the slag with particle size less than10mm was added with the best ratio of13.33%,and the removal rates of arsenic,chromium and zinc were87.09%,99.31%and99.99%.The use of slag to treat heavy metal wastewater could be an effective method.
