城市污泥农用资源化研究进展

Research Advance in Agricultural Application of Municipal Sewage Sludge

污泥农用具有投资少、能耗低、运行费用低等优点,正在成为世界上各国主要的污泥处置方式,为此综述了城市污泥农用资源化方式的应用特点和发展状况,并通过对目前污泥农用资源化的方法进行分析和比较,认为超富集植物和低累积作物/富钾植物进行套种处理城市污泥同时进行农用资源化利用具有明显的优势,将为城市污泥的处理处置提供新的思路。

Agricultural application of municipal sewage sludge （MSS） has the advantage of little investment, low energy consume and low management cost, which has been becoming the main method of MSS treatment. This paper summarized the applied characteristic and developing state of the methods of agricultural application of MSS, and analyzed and compared those methods. The method of MSS treatment that co - planting between hyper - accumulator and low accumulative plants （ a K - high - accumulating plant） would supply new consider of MSS treatment, for it has obviously advantage during the agricultural application of MSS.
