摘要
利用ＫＣｌ,ＭＨ４Ａｃ,ＨＣｌ,ＮａＯＨ四种化学浸提液将污水厂初沉污泥中的活性铝溶出,根据不同的溶出机理,得到铝的各种化学形态,进行定量测定,得到污泥中活性铝的形态分布,为污泥的合理利用提供了一些信息．
In this paper, the active aluminum species leached from sludge by four chemical extraction so-lutions were studied. There are potassium chloride, ammonium acetate, hydrochloric acid and sodium hydroxide solutions. According to the different mechanisms of leaching, various chemical species of aluminum were obtained. The leaching aluminum species were determined, and the per-centage of distribution of the active aluminum species from sludge leaching was calculated.
