摘　　要：市政污水处理厂在处理污水的同时会产生大量污泥,如果处理不当,将会造成严重的环境污染和资源浪费。污泥制备吸附剂因能使其稳定化而展现出特殊前景。利用市政污泥制备活性炭,不仅可以实现污泥的资源化利用,而且可以生产用途广泛的廉价吸附材料,具有良好的环境效益和社会效益,引起国内外研究者的高度关注和深入研究。综述了国内外污泥活性炭的制备研究进展及其在污水处理中的应用研究现状,综合分析了污泥活性炭对废水中污染物的吸附效果。Municipal wastewater treatment plant will produce a large number of sewage sludge in the meantime of disposing sewage,if handled improperly,it will cause serious environmental pollution and waste of resources.One option that exhibits especial promise,due to its potential to valorize the sludge,is converting sludge into adsorbents.Preparing activated carbon with municipal sludge can not only achieve the goal of resource utilization but also produce the versatile and low-cost adsorbent materials.Sewage sludge-based activated carbon has caused great concern of many researchers and in-depth research due to its good environmental and social benefits.An overview of domestic and foreign research progress of the preparation of sewage sludge-based activated carbon and its application in wastewater treatment are reviewed.Besides,a comprehensive analysis of adsorption effect of pollutants in wastewater on sewage sludge-based activated carbon is conducted.
