摘要
随着城镇化进程的加快,城镇污水的排放量也在不断增加,城市污水厂污泥的处理处置问题迫在眉睫。针对城市污水处理厂污泥的特点,结合污泥处理处置的减量化、稳定化、无害化、资源化原则,文章对近几年国内外污泥处理处置及综合利用的方法进行了概述,包括污泥处理的工艺流程、污泥的卫生填埋、焚烧处理、土地利用、堆肥处理、碱性稳定化、湿式氧化、能源利用和作建筑材料及其它综合利用方法,提出了污泥处理处置技术的发展趋势。
With the development of urbanization, urban waste water emissions are also increasing, municipal sewage sludge treatment and disposal are imperative. In this paper, in view of characteristics of municipal sewage treatment plant sludge, combined with the principles of sludge treatment and disposal ： reduction, stabilization, decontamination and recycling. The methods of sludge treatment and disposal and comprehensive utilization at home and abroad in recent years are summarized, including the process of sludge treatment, sludge sanitary landfill, incineration, land use, composting, alkaline stabilization, wet oxidation, energy use and utilization for constru - cion materials and other methods. The trends of development of technique for sludge treatm - ent and disposal are presented.
