瑞典污泥土地回用管理体系的剖析及启示

Analysis and Inspirations of Sludge Land Application Management System in Sweden

污泥土地回用因其具有高效、经济与可持续性,成为目前主流的污泥处置方式之一,但是污泥中含有的重金属、持久性有机污染物等物质,为污泥土地回用尤其是农业土壤利用带来了很大的风险。当前多数国家都根据污泥生产方式及污染物含量对污泥进行了分级,并在此基础上建立了污泥土地利用的标准规范,但缺乏污泥利用全过程的系统性管理措施。就瑞典REVAQ污泥回用管理体系的组成及相关内容进行了介绍与剖析,可对我国污泥土地回用管理体系的建立提供参考。

Due to its high efficiency, cost-effective and high sustainability, the application of sludge into land are the major solution of sludge disposal. For the existence of containments like heavy metal and organic chemicals, the application of sludge to agricultural land has raised discussion on risk assessment. At present, most of the countries have established sludge application guidelines for thresholds of contaminants and the associated classifications. However, there is a lack of systematic management measures for the whole process of sludge utilization. With introducing the composition and related con- tents of Swedish REVAQ sludge reuse management system, which can provide the reference for the estab- lishment of sludge land application management system could be provided in China.
