摘　　要：底泥原位覆盖技术是一种修复效果较好、工程造价较低的水体底泥修复技术。其相对于底泥异位处理更加简便、经济、有效,且能避免异位处理时底泥对水体的二次污染,并降低生态风险。相对于其他原位修复技术,底泥原位覆盖更加快速、有效,且对生态环境的影响较小。影响底泥原位覆盖效果的因素较多,而其关键点在于覆盖材料的选择。材料性质基本决定了其对底泥中污染物的控制效果。主要介绍了研究较为成熟且具有一定应用前景的覆盖材料,综述其各自的原理、特点,并对不同覆盖材料在使用中所暴露的问题进行了分析,提出了相应建议。同时结合中国环境现状,对底泥原位覆盖技术的前景进行了展望。As an effective and economical technology in contaminated sediments remediation,in-situ capping technology shows a high economical efficiency,convenience and effectiveness in comparison to ex-situ remediation.It can avoid the secondary pollution that is induced by ex-situ remediation and reduce the ecological risk.Compared with other in-situ remediation technologies,in-situ capping works quickly and has a low impact on water ecology.There are many factors that can affect the sediment in-situ capping,and the key factor is capping materials’properties,which is the most important factor in pollutant control.This paper mainly introduced the most mature or promising capping materials which could be used in in-situ capping,reviewed their mechanisms and characteristics,further discussed the problems exposed in the applications of different sediment capping materials,and gave some suggestions in response.At the same time,in consideration of the current situation of environment in China,the prospect of in-situ capping technology in sediment treatment was proposed.
