摘　　要：人工填料和曝气技术的组合使用是河道原位修复的常用方式,在杭州市已实施原位修复的河道中,80%同时采用了这两种技术。对河道水体原位修复中常见的人工填料和曝气两种技术按照不同类型进行了介绍。结合工程实例,对不同人工填料的比表面积、材质成分、填料特点、安装方式等进行了比较;对不同种类的曝气技术从安装及运行、对外界影响、受制因素、应用效果、适用河道类型等方面进行了分析和综合比较。提出了适合原位修复的4种常见模式及其适用条件,并分析了在河道水体原位修复中应用人工填料及曝气技术时需要注意的问题。研究成果对其他类似河道水体原位修复具有一定借鉴意义。The combination use of artificial fill materials and aeration technology is a normal practice of in-situ river remediation nowadays.The two technologies had been adopted simultaneously in eighty percent of the remediated river channels in Hangzhou.We introduced the artificial fill materials and aeration technology in terms of their vari⁃ous type and then analyzed and compared the specific surface area,material composition,filling characteristics and installation methods of different artificial fillers with real engineering examples.We also analyzed and com⁃pared different types of aeration technologies from the aspects of installation and operation,influences on external environment,restricting factors,application effectiveness and applicable river channels.We presented four com⁃mon modes and conditions that are suitable in-situ river remediation as well as the problems to-be-paid attentions when applying the two technologies.This paper provides certain references for other similar in-situ river remediation.
