介绍了目前污泥质活性炭吸附剂制备方法及在治污方面的应用进展。阐述了污泥直接干化法、传统活性炭活化碳化法和微波活化碳化法等制备方法的研究现状,指出向污泥中添加金属氧化物、聚合物以及相应的辅料,可改变污泥碳的结构,提高吸附去污效能。初步探讨了污泥质活性炭吸附剂的除污机制和朗格缪尔及弗兰德利希模型的应用研究。
The preparation method of sewage sludge adsorbents and its application development in the field of decontamination are introduced. The recent progress in preparation with direct drying method,traditional sludge activation carbonization method and microwave activation carbonization method are described. It is demonstrated that the structure of sludge carbon can be changed and the effiency of adsorption and decontamination can be improved through addition of metal oxide,polymer and relevent accessories into the sludge. Moreover,the decontamination mechanism of sludge adsorbents and the application of Langmuir Freundlich Models are also discussed.
