摘要
在城市化发展进程中,随着环境质量标准、污水处理率和处理程度的提高,污泥产量大大增加,如何将这些污泥无害化并进行有效利用是世界各国共同面临的难题之一。综述了国内外污泥园林绿化资源化利用的状况和存在的主要问题,指出要使污泥园林绿化资源化利用而不给城市环境带来危险,就必须对污泥进行适当的处理,控制污泥中的污染物含量,并科学地施用。
In the process of urbanization development, the output of sewage sludge increased greatly, with enhancement of environmental quality standards and the increasing of treatment rate and deepening of treatment degree of wastewater. How to treat and disposal it in order to minimize its harm and to make effective use became a worldwide concern, In this paper, current status of resource utilization of sludge in landscaping was reviewed and major existing problems were put forward, In order to decrease the hazards of sewage sludge utilization to urban environment, proper treatment of sludge should be adopted. Pollutant content in sludge should be controlled through rational treatment.
