城市污泥资源化利用研究现状

介绍了城市污泥性质及常规处理、处置情况,从污泥农林利用、建材化、能源化、制吸附剂、污泥中蛋白质的有效利用及制聚合物复合材料等几方面探讨了国内外污泥资源化利用的现状,阐述了污泥建材化利用能更好地利用污泥中的有机及无机物质,同时更有效地消减污泥中的有毒有害物质,并展望了污泥建材化制品在城镇化不断深入的进程中将具有更广阔的发展空间。

Present Research Situation of Municipal Sludge Resources Utilization

In this article the nature and the treatment of municipal sludge was introduced,and the present situation of domestic and foreign sludge resources discussed,including used in farming,building materials,energy and adsorbent,and the effective utilization of protein in sludge and making polymer materials. Among these uses the building material was the better path to utilize the organic and inorganic matter in the sludge,and to reduce the deleterious substance. Finally it was forecasted that the sludge building materials product would have a broader developing space with the development of cities.
