摘　　要：原位修复是一种可靠、卓有成效的河道水体净化修复技术,具有治理费用低和最大程度降解污染的特点,适合于污染严重、流量较小的河流水体。本文概述了河道曝气法、生物接触氧化、河流湿地处理和生态浮床等河道原位处理技术的原理、发展及应用情况,其中河道曝气和生物接触氧化起步早,技术较为成熟,为早期污染水体治理贡献很大,相对河流湿地处理和人工浮床起步晚,但成本低,耗资少,处理效率又高,具有很大的发展空间。这些工艺都是经济、有效以及符合可持续发展要求的生物生态技术,在国内外发展比较迅速,但在进一步改进的前提下,其应用前景将十分广阔。In-situ treatment is a reliable and effective technology for river purification. With low cost and most potential of control pollution, this technology is very suitable for treating the water with low flow rate but serious pollution. This paper introduces the principle, development and application of in-situ treatment technologies including river aeration, biological contact oxidation, constructed wetland and ecological floating bed. The technologies of river aeration and biological contact oxidation were developed early. They are very mature, having a great contribution for wastewater treatment. The technologies of ecological floating bed and constructed wetland were developed later, but having advantages of low cost, high rate and good developing potential. All of them are economic, effective biological-ecological technologies in accordance with sustainable development. With fast development, they will have bright prospect of application after further improvement.
