摘　　要：城市污泥是伴随工业和生活污水处理衍生出来的一种可再生资源,由于其内部含有大量的重金属元素、细菌以及其他有毒害物质,污泥处理和利用面临较大困难。中国城市污泥处理大多以填埋、焚烧或简单脱水处理后露天堆放,污泥处理率较低,且易引发巨大的环境污染问题。但城市污泥中含有大量有机质以及氮磷钾成分,尤其在土地整治领域、建筑材料制备以及污损土地修复领域具有显著的效果,既能减少城市污泥造成的巨大危害,又能进行资源合理利用,具有显著的现实意义和发展前景。Municipal sludge is a renewable resource derived from industrial and domestic sewage treatment.Due to its large amount of heavy metal elements,bacteria and other toxic substances,sludge treatment and utilization are facing great difficulties.Most of the urban sludge treatment in China is deposited in the open air after landfill,incineration or simple dewatering.The sludge treatment rate is low and it is easy to cause huge environmental pollution problems.However,municipal sludge contains a large amount of organic matter and NPK components,especially in the field of land remediation,construction materials preparation and land remediation,which can reduce the huge harm caused by urban sludge and make resources reasonable utilization,with significant practical significance and development prospects.
