以废铁和煤基活性焦为基质的微电解处理棉黑液研究

Treatment of Black Cotton Wastewater by Micro-Electrolysis with the Lignite Activated Coke and Waste Iron as Medium

以废旧铁刨花和煤基活性焦为基质,利用微电解法对棉浆黑液进行了预处理,对处理条件进行了优化研究,并对处理前后的介质进行了电镜观察。结果显示:铁屑和活性焦为基质的微电解法对棉黑液有很好的处理效果;扫描电镜观察表明:处理前后废旧铁刨花表面形态发生了明显变化。

Lignite activated coke and waste iron were used as medium of micro-electrolysis to remove organic compounds from black cotton wastewater.Environmental scanning electron microscope （ESEM） was investigated to characterize waste iron the before and after reaction.The results showed that the AC was an ideal medium of micro-electrolysis.The ESEM photographs reveal that the surface of waste iron varies evidently after reaction.
