摘　　要：污泥是废水经污水处理厂处理后残留的固体残渣,其中存在多种有毒有害物质,若处置不当,可能对生态环境造成极大危害。面对我国节能减排和环境保护的客观要求,实现污泥的减量化、无害化、资源化,成为污泥处理处置的重要任务。污泥生物炭是污泥在一定条件下热解的产物,具有比表面积大、表面基团丰富且营养元素含量高等特点,在土壤改良、重金属去除和水处理等领域均有应用,因此利用污泥制备生物炭已发展成为污泥资源化利用的有效途径之一。从总结污泥生物炭制备与改性方法开始,对污泥生物炭性质及影响因素进行分析,重点阐述了污泥生物炭在环境、农业、高级氧化水处理和储能材料领域的研究及应用现状,并对污泥生物炭未来的研究方向和发展前景进行了展望。As one of the most important solid residues of wastewater treatment,sludge contains various toxic and harmful substances.If it can be not treated properly,it may cause great harm to the ecological environment.To meet the urgent requirements of energy conservation,emission reduction,and environmental protection in China,achieving reduction,harmlessness and resource utilization of the sludge has become an important aim for sludge treatment and disposal.Sludge biochar,produced from sludge pyrolysis,performs super features including large specific surface area,rich surface groups and high nutrient content.It has been applied in various fields,such as soil improvement,heavy metal removal,and water treatment.Therefore,the preparation of biochar from sludge has become one of the effective ways for sludge resource utilization.In this article,preparation and modification methods of sludge biochar were summarized,as well as the properties and influencing factors of sludge biochar.The applications of sludge biochar in the fields of environment,agriculture,advanced oxidation water treatment,and energy storage materials were also introduced.Finally,future researches and development prospect of sludge biochar were discussed.
