制革污泥的处理方法与资源化

Safe Treatment and Reuse of Tannery Sludge

从安全和经济性角度出发,分析了目前制革污泥的几种处理方法,如填埋、焚烧、化学试剂浸出-萃取、生物淋滤和制建筑材料等.经对比后发现,生物淋滤法具有成本低,且无二次污染风险的特点,可加以推广应用.

Various tannery sludge treatment methods,such as landfilling,incineration,chemical reagent leaching and extraction,bioleaching,and building materials making,are compared from the security and economic point of view.The comparison shows that bioleaching is the best consideration from the security and economic point of view,because cost is low without secondary pollution,and thus suitable for wide use.
