河道底泥污染释放机制和修复技术研究进展

Progress research on pollution sediment release mechanism and remediation technology in river channel

关于去除底泥中氨氮、磷、有机物和重金属的研究有很多,包括物理、化学和生物的处理,然而基本是基于实验室研究层面的。文章认为底泥修复应遵循分类施策原则,结合污染类型和修复后土壤作用来选择修复方案,除此之外,由于土地资源紧张以及底泥中蕴含着可利用的营养和能源,资源化利用的前景广阔,如农林业的堆肥、建筑用材等等,底泥资源的可待开发程度高。

There are many studies on the removal of ammonia nitrogen,phosphorus,organic matter and heavy metals from sediment,including physical,chemical and biological treatments,but they are basically based on laboratory research.According to the article sediment repair should follow the principle of classification taking measures,combined pollution types and soil function to select the fix after repair,in addition,due to the shortage of land resources and contains the available nutrient in sediment and energy,recycling use of broad prospects,such as farming soil fertilizer,building material,etc.,sediment resources yet to be developed continuously improved.
