摘　　要：生态浮床和生物接触氧化组合技术是依据陆生植物的养分吸收特性,利用无土栽培技术,通过植物根系的吸附和吸收作用,富集污染水体中的N、P等营养元素,同时利用在生物填料表面形成的生物膜对水体进行净化.从而实现改善水质,美化水域环境和保护水生态环境的目的.通过对公园水体的静态试验,结果表明,组合技术对水体中N、P等的去除率要高于单一的生态浮床技术,具有很好的应用前景.The development of biological floating bed and biological contact oxidation combination technique is based on the characteristics of land plants of absorbing nutrients. And soilless culture technology was used for implantating suitable land plants in water. N and P in the waste water body can be absorbed by the plants root system. At the same time, water body also can be purified by the bio-membrane formed on the surface of bio-media. As a result, water bodies are cleaned, aquatic environment is beautified, and ecosystem well maintained at the same time. By the static experience to the park water body , the results showed that the removal rate of N and P by the combination technique was higher than with single biological floating bed. The combination technique has prospects for application in water body purification on a large scale.
