景观水体的修复技术

Remediation Technology for Landscape Waters

针对目前景观水体存在的问题,本文简单介绍了水景水体的修复原则和方法。结合景观水治理工程的实例,分别从物理、化学和生物方法三个方面总结了景观水体的各种污染控制和管理措施,分析其优缺点及适用性。详述了水生植物、水生动物、微生物以及它们之间相互结合处理富营养化水体的修复技术。提出景观水体污染控制的关键是将污水处理的常规处理技术与生态处理技术有效结合。通过生物-生态技术的集成,全方位增加有益水质净化的水生生物,是富营养化水体生物-生态修复技术有效的强化手段。

To the problems existing in landscape water body, this paper introduces the principles of the restoration and the methods. Combining with the examples of the project of landscape water treatment, all kinds of control and management measures for the pollution of landscape waters were sum up from three aspects of physical, chemical and biological methods, and the advantages, disadvantages and applicability of these methods have also been analyzed. The remediation technology of eutrophic water body by using aquatic plants, aquatic animals, microorganisms and their interaction were expatiated. Key point of pollution control for landscape waters is concluded to efficiently combine conventional treatment with ecological treatment. It is an effective way to deal with the eutrophic water with ecological restoration technology combining all kinds of biotechnology of water restoration and increasing the number of species of the aquatic plant which can purify the water.
