Embodiment 1

[0060] (1) Treat eutrophic water bodies

[0061] On November 20, 2009, the algae bloom ecological control system based on micro-topography modification of the present invention was used to treat the eutrophic Taihu Lake water body.

[0062] Control engineering design basically includes: algae "algae bloom" comprehensive control system integrates and applies various technologies such as terrain transformation, wetland ecological revetment, wetland plant optimization configuration, biological chain restoration, and hydraulic connectivity. The specific projects include waterfront design, water system transformation, Animal and plant restoration, etc. The project is divided into six processing units, which use the movement of water to collect a large number of harmful algae produced after the "algae bloom" and carry out harmless treatment through artificial measures; the project can also intercept the spread of harmful algae to the shore of Sanshan Island, eliminating the harmful ...

Abstract

The invention discloses an algal blooming ecological control system based on micro-terrain reconstruction, an ecological method for controlling algal blooming and application, and belongs to the technical field of ecological engineering. The algal blooming ecological control system based on micro-terrain reconstruction integrates and adopts a terrain reconstruction technology, a wetland shore zone slope protection technology, a wetland vegetation planting technology and a hydrological Unicom technology. According to the ecological control system and the ecological method disclosed by the invention, the generation of the algal blooming can be effectively restrained, a large number of harmful algas generated after the algal blooming is collected at the same time, and the diffusion of the harmful algas to a near shore can also be intercepted, so that the adverse impact on nearshore water quality, island air environment and landscape is eliminated.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, and relates to an algae bloom ecological control system based on micro-topography transformation, an ecological method and application for controlling algae bloom. Background technique [0002] In the past 10 years, eutrophication and algae blooms have occurred frequently in wetland water. As the "kidney of the earth", the eutrophication of wetland water, the reduction of biodiversity and the vulnerability of biological chains have always been hot and difficult issues in the field of wetland science. With the development of human society and economy and the improvement of living standards, people's domestic water, industrial and agricultural water use have increased sharply, the eutrophication of wetland water has become increasingly serious, and algae blooms have occurred frequently, such as the Taihu Lake cyanobacteria bloom in 2007 and Chaohu Lake in 2010. Blue-green algae bloo...
