摘要
受污染底泥的修复已经成为水环境修复中的重要组成部分,在底泥中注入硝酸钙则是近年发展起来的一种污染底泥原位处理技术。全面分析了硝酸钙投入后对水体及底泥中氮、磷、硫迁移转化的影响,并介绍了这一技术在国内外的研究进展和应用状况。
The remediation of polluted sediment has become an important part of water environmental remediation. The in-situ treatment of polluted sediment by injecting calcium nitrate into sediment is a newly developed technology. In this paper, the effects of calcium nitrate on the transport and transformation of nitrogen, phosphorus and sulfur in water and sediment are comprehensively analyzed, and the research and application status of this technology at home and abroad are introduced.
