Abstract

The invention discloses a curtain type manual down-flow device combined with fish reefs, and belongs to the technical field of ocean anoxia solving; the curtain type manual down-flow device comprisesfloating balls, ropes, curtain cloth, a steel fixing frame, artificial reefs and anchoring structures, wherein the floating balls are connected with the steel fixing frame through the ropes, the curtain cloth is fitted on the steel fixing frame, reinforcing ribs penetrate the steel fixing frame, and the artificial reefs are connected to the bottom of the steel fixing frame and fixed on the seabedthrough the anchoring structures. When oxygen-enriched water entrained by tidal currents flows through the device, a down-flow is generated under the induction of the inclined curtain cloth and is discharged after being mixed by the artificial reefs at the bottom of the device, and the discharged oxygen-enriched water is mixed with surrounding anoxic water so as to alleviate the anoxia problem ofthe seabed.

Description

technical field [0001] The invention relates to the technical field of solving marine hypoxia, in particular to a curtain type artificial downflow device combined with fish reefs. Background technique [0002] Hypoxia is increasing in estuarine and coastal marine ecosystems around the world. Lack of dissolved oxygen (DO) in water poses a threat to coastal ecosystems by reducing aquatic biomass and reducing biodiversity. There are many factors that cause coastal hypoxia, mainly involving global climate change, eutrophication and water stratification. According to statistics, in the world's coastal waters, there are more than 400 continuous or seasonal hypoxic regions covering an area of ​​245,000 square kilometers, including the Baltic Sea, the Black Sea, the Yangtze Estuary, and the Gulf of Mexico. [0003] Ocean hypoxia is related to the health of the marine ecosystem, which can lead to the loss of biological habitats, damage or reduction of biological populations, and af...
