摘要

With reference to the specific comments made by Dr. Caetano C. Dorea on our paper , we offer the following response: The type of industrial wastewater simulated in our study is a composite of textile and garment washing and metal finishing wastewater (diluted by domestic wastewater). These industries predominantly occur in Sri Lanka and these wastewaters were found to contain high levels of Al. Previous studies carried out in industrial areas of Sri Lanka especially Ratmalana-Moratuwa area revealed that on average textile and garment washing and metal finishing wastewaters contain Al levels of around 5.62 mg/L with high levels of SO_4~(2-) too. Therefore, we added Al in the form of AR grade aluminum sulfate to simulate Al rich wastewaters. Moreover, it has been revealed that the groundwater in Ratmalana-Moratuwa area (which has a high content of sand in the soil with a shallow water table) where untreated Al laden wastewaters are disposed also contain high Al levels of around 5.6 mg/L.

Dorea博士在我们论文上的具体评论，我们提供以下答复：在我们的研究中模拟的工业废水类型是纺织服装洗涤和金属整理废水（由生活废水稀释）的复合物。 ）。这些工业主要发生在斯里兰卡，发现这些废水中含有大量的铝。先前在斯里兰卡工业地区，特别是拉特马拉纳-莫拉图瓦地区进行的研究表明，平均而言，纺织服装洗涤和金属整理废水中的Al含量约为5.62 mg / L，并且SO_4〜（2-）含量也很高。因此，我们以AR级硫酸铝的形式添加了Al，以模拟富含Al的废水。此外，已经发现，未经处理的载有Al的废水被处理的Ratmalana-Moratuwa地区（土壤中的沙子含量高，地下水位浅）中的地下水也含有约5.6 mg / L的Al。
