How To Turn the Sludge of Sewage Treatment Plant into Resources

污水处理产生的污泥中含有不同的有机物和无机污染物,其处置以减量化、稳定化、无害化和资源化为目的。污泥的土地利用、污泥消化制沼气、污泥燃料化技术、污泥的建材利用及污泥的其他几种资源化处理方法,有利于污泥处理效率的提高和环境的改善。

The sludge produced in sewage treatment contains different organic a nd inorganic pollutants. The reduction of volumes, stabilization of nature, non -poisonousness and resourceful treatment are the aims of their treatment. This paper mainly introduces the technology of turning sludge into resources, the uti lization of sludge in agriculture, the digestion of sludge to produce methane, t he technology of turning sludge into fuel and building materials, and other slud ge treatment technologies. These technologies can enhance the efficiency of slud ge treatment and improve the environment.
