摘要
污泥是污水处理的产物,其内部组成非常复杂,包括有机残片、细菌菌体、无机颗粒等,由于其含水率高,内部含有有机物,因此极易腐化,很难对其进行固液分离处理。但是,污泥中存在可利用资源,在可持续发展战略实施的背景下,如何对污泥进行资源化利用是极为重要的问题。本文从传统污泥处理方法存在的问题入手,详细阐述了污泥资源化利用的方法,以供参考。
Sludge is a product of sewage treatment,and its internal composition is very complex,including organic debris,bacterial cells,inorganic particles,etc,because of its high moisture content and organic matter inside,it is extremely perishable and difficult to carry out solid-liquid separation treatment.However,there are available resources in the sludge,in the context of the implementation of the sustainable development strategy,how to use sludge as a resource is an extremely important issue.This paper starts with the problems of traditional sludge treatment methods,and elaborates on the methods of resource utilization of sludge for reference.
