生态浮床技术的应用及研究新进展

Application and New Research Process of Ecological Floating Bed Technology

近年来为解决我国水域富营养化问题,一种以水生植物为主体,运用无土栽培技术原理的生态浮床技术应运而生。该技术以其治理富营养化水体的独特优点,既美化保护生态环境,又带来了一定的社会效益,且成本低,是一种极具发展潜力的技术。但是影响该技术的因素也较多,主要包括浮床水生植物选型、水体污染程度的差异、植物的种植方式和周边环境条件等。虽然目前该技术的成功应用实例不断增多,但是仍然存在一些亟需解决的问题,如植物根系和根际微生物群落相互作用的机理不明确、气候条件的不利影响、制作生态浮床材料的二次污染以及如何与其他污水处理技术相组合等。

In recent years, in order to solve the problem of water eutrophication in China, an ecological bed technology using aquatic plants and soilless cultivation principle emerges as the times require. With the special advantage of treating eutrophic water, this technology can beautify and protect ecological environment and bring social benefits, and its cost is low, thus it may be a technology with high development potential. However, there are some influence factors including the choice of aquatic plants, the difference in water pollution degree, the planting modes of plants and the surrounding environmental conditions. Although there are more and more successful applications, this technology has some problems to be solved, such as the unclear interaction principle between root system and microorganisms, the adverse effect of climate conditions, the secondary contamination from floating bed materials, the combination with other techniques and so on.
