摘　　要：在污水处理技术创新、处理效率提升的背景下,污水处理厂排放的污泥如何进行科学处理,成为关注的焦点。由于污泥中含有较多的重金属、有机污染物、病原微生物,如果直接填埋必然会造成环境的污染和生态的破坏。该文首先介绍了几种实用性、无害化的污泥处置方法,包括污泥焚烧法、土地利用法、厌氧消化法等;随后介绍了污泥在农业、工业、环保等各个领域的资源化利用方法,并对污泥资源化利用的发展前景进行了展望。Under the background of innovation of sewage treatment technology and improvement of treatment efficiency,how to carry out scientific treatment of sludge discharged from sewage treatment plant has become the focus of attention.Because the sludge contains more heavy metals,organic pollutants and pathogenic microorganisms,direct landfill will inevitably cause environmental pollution and ecological damage.In this paper,firstly,several practical and harmless sludge disposal methods are introduced,including sludge incineration method,land use method,anaerobic digestion method,etc.Then the utilization methods of sludge resource in agriculture,industry,environmental protection and other fields are introduced,and the development prospect of sludge resource utilization is prospected.
