摘　　要：本文重点阐述了不同方法制备污泥吸附剂(SBA)及其对水体中各类污染物吸附研究的进展。经查阅文献发现,SBA的制备方法可分为碳化法、物理活化法、化学活化法,其中化学活化法能够制备出比表面积和孔体积均较大的SBA,且制备过程简单,从而展现出优于其他两种制备方法的吸附能力,但也存在成本较高的缺陷。因此,研究开发一种低成本、高效、环境友好型吸附剂显得尤为重要。经过改性后的污泥基吸附剂可以脱离主要因素影响大幅改善对某类污染物的吸附性能。This paper focused on the preparation of sludge adsorbent(SBA)by different methods and the research progress of its adsorption on various pollutants in water.It was found that the preparation methods of SBA can be divided into carbonization,physical activation and chemical activation,among which chemical activation can prepare SBA with large specific surface area and pore volume,and the preparation process was simple,therefore,the adsorption capacity was better than that of the other two preparation methods,but the cost was higher.Therefore,the research and development of a low-cost,efficient,environment-friendly adsorbent was particularly important.The modified sludge-based adsorbent can remove the influence of main factors and greatly improved the adsorption performance of certain pollutants.
