Ascending and descending dual-buoyancy regulation sinking bed-floating bed water quality purification device

Abstract

The invention discloses an ascending and descending dual-buoyancy regulation sinking bed-floating bed water quality purification device. A sinking bed system is provided with a hollow sinking bed water level regulating framework; a circle of hollow outer rectangular framework is tightly fixed on the periphery of an upper rectangular frame of the sinking bed water level regulating framework; water is injected into the sinking bed water level regulating framework and the outer rectangular framework, so that the sinking bed system reaches a fixed planting water level or a growth water level. The device is characterized in that a floating bed system providing region is added to the periphery of a sinking bed; the system balance is controlled through the peripheral single floating bed system; the bed body stability is enhanced, so that the influence of environment factors on the sinking bed and a floating bed is reduced. The water level of water sinking plants in the water is regulated through the water irrigation and water pumping effect inside the sinking bed and the effect of a regulating rope; by controlling the growth position of the water sinking plants in the water, the most proper growth water level of the water sinking plants in the water can be realized; the natural environments are simulated to the maximum degree. The water sinking plants and water emerging plants are combined; the water body ecological system recovery can be facilitated to the maximum degree.

Description

technical field [0001] The present invention relates to the ecological construction and ecological restoration of natural rivers, artificial rivers, lakes and other places, and to rivers and lakes with eutrophication, serious water quality damage, degradation of aquatic plants, low water transparency, and too deep water. It is in the field of ecological restoration and water purification of sediment-type and hard-type water bodies with lakes. At the same time, the invention relates to the improvement of the purification device of the original sedimentation bed-floating bed coupling system, which enhances the stability of the bed body, thereby weakening the impact of environmental factors on sedimentation. bed, floating bed, especially a new sinking bed-floating bed coupled water purification device. Background technique [0002] At present, among our existing patented technologies, the technology of CN104743673A adopts the technology of combining sinking bed and floating bed...
