利用造纸污泥处理重金属废水的研究

The Research of using papermaking sludge to deal with heavy metals in wastewater

以某造纸企业的污水处理厂为研究对象,利用生产中产生的剩余活性污泥和浓缩后的黑液及一些废弃的秸秆材料,在经过碳化、活化、酸化等一系列过程研究出可以去除水中重金属的生物炭,以达到以废治废的目的。

In a papermaking wastewater as the research object ot the enterprise, using me reslaua~ activated sludge and the production of concentrated black liquor and some abandoned straw materi- al, through carbonization, activation, acidification and a series of research in the process of the biochar can remove the heavy metals in water, in order to achieve the purpose of using waste treat waste.
