生物生态技术在城市景观河道水环境改善中的应用研究

Study on the Application of Biological and Ecological Technology at Improving Water Environmental Quality for Urban Scenery River

简要介绍了生物-生态水体修复技术的原理和工艺方法,受污染水体的生物-生态修复技术是利用人工培育、筛选出来的植物和微生物的生命活动,对水中污染物进行转移、转化及降解作用,从而使水体得到恢复。从本质上说,该技术是人们遵循生态系统自身规律、并强化其水质净化能力、达到治污目的的一种尝试,其生态系统中的生物种类多种多样,高效去除氮、磷、COD等污染物,并处于人为的控制之下。利用生物-生态技术治理城市水环境,恢复自然水体生态系统的功能,在国内外都是一种新的探索,特别是在城市景观水域,将水质改善、水体富营养化防治与城市景观功能有机结合,更是处于技术的前沿。

A technics of biological and ecological water treatment technology is introduced in this paper, this technology makes use of plant and microorganism that is artificially cultivated and chosen to take pollutants from water and to improve water quality. Actually, this technology keeps to the rule of ecological system and strengthen the ability of water quality improvement. The species of biology in this ecological system are abundant, them can effectively remove pollutants of COD. nitrogen and phosphor from water under the control of people. It is a fire-new research to utilize biological and ecological technology for improving water environment and repair hydro- ecosystem. Especially, it is in the front of research in the world to combine water improvement with city landscaping for urban scenery river.
