市政污泥农业利用可行性分析与发展建议

Feasibility Analysis and Development Suggestions for Agricultural Utilization of Municipal Sludge

市政污泥是污水处理的副产物,其中含有大量有机物和氮磷等营养物质,具有很好的农业利用潜力。但是,由于污泥中含有重金属等有害物质,阻碍了其在农业生产中的应用。通过对相关政策标准和污泥处理技术的研究,探讨了污泥农业利用的可行性,并对目前利用过程中存在的问题进行了分析,提出了相应的发展建议。

Municipal sludge is a by-product of sewage treatment, which contains a lot of nutrients such as organic matter and nitrogen and phosphorus and has a good agricultural utilization potential. However, the application of municipal sludge in agricultural production is hampered by the presence of heavy metals and other harmful substances in the sludge. Through the study of related policy standards and sludge treatment technology, this paper discussed the feasibility of agricultural utilization of sludge,analyzed the existing problems in the current utilization process and put forward corresponding development suggestions.
