Ecological restoration device adopting micro-nano bubbles to realize oxygen aeration and activation

Abstract

The invention relates to an ecological floating island applied to ecological control of drain outlets for river water bodies, and discloses an ecological restoration device adopting micro-nano bubblesto realize oxygen aeration and activation. Main units of the ecological restoration device adopting the micro-nano bubbles to realize oxygen aeration and activation comprise an artificial floating island, a micro-nano bubble aerator and ancillary facilities; the ecological restoration device comprises a control system (1), a fan (2), aquatic vegetation (3), a plant floating bed (4), a pipe assembly (5), a micro-aerobic filament assembly (6), a water level control device (7) and a bracket (8). The ecological restoration device adopting the micro-nano bubbles to realize oxygen aeration and activation is simple in structure, convenient to use and low in energy consumption, dissolved oxygen in the water body is rapidly increased, and under the synergistic effect of the aquatic plant root system and various different aerobic, anoxic and anaerobic microorganisms, harmful substances are decomposed, and propagation of harmful algae and fungi is inhibited; besides, the device is high in bearing capacity, the quantity of plantable plants is correspondingly increased, and landscape and sewage control effect are better.

Description

technical field [0001] The invention belongs to the field of ecological restoration, and in particular relates to an ecological restoration device for increasing oxygen and activating micro-nano bubbles in sewage outlets of rivers and rivers. Background technique [0002] In recent years, water pollution has become a growing concern. Water pollution in lakes, reservoirs, and urban rivers is mainly caused by eutrophication of water bodies. Due to the poor fluidity and low self-purification ability of lakes, reservoirs, and urban rivers, eutrophication is relatively serious, that is, due to the discharge of excess nutrients (mainly nitrogen, phosphorus, potassium, etc.) into natural water bodies, algae and other plankton Rapid reproduction, resulting in deterioration of water quality. The ecological restoration device is a kind of habitat structure that can provide a variety of organisms. It consists of an artificial floating island platform, plant populations and a fixed sy...

Problems solved by technology

However, aeration and oxygenation have a good effect on increasing dissolved oxygen in water. The ordinary air bubbles produced by conventional aeration technology have a large diameter and a fast rising speed, and cannot stay in water for a long time, so the effect of oxygenation is very small.
