化学污泥中铝盐混凝剂的回用

Recycling Aluminum Coagulant from Chemical Sludge

在自来水厂和污水处理厂中 ,铝盐作为混凝剂已得到了广泛的应用。在絮凝过程中所产生的化学污泥不仅体积大 ,而且还含有大量的铝盐 ,若不加以回用处理 ,会对环境产生不良影响。对几种铝盐污泥的回用方法进行了阐述 ,以便进一步探索综合利用含铝盐化学污泥的有效途径。

Several methods for reclaim aluminum salts from sludge of water and wastewater treatments are reviewed with a focus on the techniques which are effective in removing contaminants in the recycled aluminum salts.
