城市污水处理厂污泥的综合利用探讨

Comprehensive Utilization of Sewage Sludge in Municipal Wastewater Treatment Plant

城市化进程加快,城市污泥排放量日益增多,污泥中含有大量的有机物质、病原菌、寄生卵、重金属及盐类等成分,污泥的综合利用主要利用污泥中的有效成分将污泥做成肥料、饲料、能源燃料、化工原料、建筑材料等,实现变废为宝,这也是城市污泥处理和资源化的主要发展趋势。

With the progress of urbanization, emissions of municipal sewage sludge increases gradually. The mare compounds of sewage sludge are organic substances, pathogenic bacteria, parasitic eggs and heavy metals and salt, etc. The comprehensive utilization of sludge are mainly focused on production of fertilizers, fodders, energy fuel, chemical and.building materials using available substance of sewage sludge, to change waste into useful material, which is considered as the main trend of sludge disposal and resource reuse.
