摘要
随着城市化进程推进,城镇工业及生活废水量逐年上升,随之而来的是产生大量污水污泥。污泥含有病原体、重金属元素等,其处置不当会对环境产生二次污染。对国内外污泥常规处理方法及固化技术、厌氧消化技术等进行了综述,总结了目前我国污泥处理方法,希望为淤泥处理的深入研究及探索资源化利用新方法提供思路。
With the advancement of urbanization,the amount of industrial and living wastewater in cities and towns is increasing year by year,and a large amount of sewage sludge is produced. Sludge contains pathogens,heavy metal elements and so on,and the improper disposal of the sludge will cause two pollution to the environment. In this paper,the conventional treatment methods,curing technology and anaerobic digestion technology of sludge at home and abroad are reviewed. This paper summarizes the current sludge treatment methods in China,and hopes to provide some ideas for the in-depth study of silt treatment and the exploration of the new method of resource utilization.
