摘要
随着城市污水处理厂处理规模不断扩大,伴随产生的污泥量也日益增多。污泥中含有大量营养元素、微量元素和有机质,可以改善土壤环境,促进植物生长,实现了资源再利用,是最适合我国现阶段基本国情的污泥处置方式和发展趋势。文章主要介绍了污泥土地利用的农用、园林绿化、土地修复几种方式的研究进展,并认为污泥在园林绿化和土地修复等方面的应用将是其土地利用的主要发展趋势。
With the city sewage treatment plant processing scale continues to expand, the sludge production is increasing day by day. Sludge which contains large amounts of nutrients, trace elements and organic matter improves the condition of soil, promotes plant growth and achieves the reuse of resources. It is the most suitable way of sludge disposal and development trend for the basic national conditions in China at present. The paper mainly introduced research progress of land utilization of sewage sludge in agricultural, landscaping, land remediation, and thought that the application of sludge in landscaping and land restoration will be the main development tendency of land utilization.
