Problems solved by technology

[0005] At present, the methods proposed by existing scientists to solve the hypoxia problem include deep water injection, bubble generator and density flow generator, etc., but the disadvantage of these methods is that they need energy consumption, and it is difficult to solve the energy problem in deep water areas, and these Most of the devices are relatively bulky and inflexible to use

Abstract

The invention discloses a tumbler type culture zone tidal pump aeration device and belongs to the technical field of solving a marine anoxic problem. Two tidal pumps are placed in a tumbler type device, and one pump is made to be constantly upright when the device is on the sea floor. The device has a simple structure and flexible design, the tidal pump consists of one segment of a 90-DEG elbow and one segment of a vertical pipe, a guide plate of the elbow portion makes a pump port constantly face the flow direction, and the horizontal tidal flow forms a down flow through the elbow to alleviate a hypoxia phenomenon in a culture zone to provide enough oxygen for benthic organisms.

Description

Technical field[0001]The invention relates to the technical field of solving marine hypoxia, in particular to a tidal current pump oxygenation device in a breeding area.Background technique[0002]In recent decades, due to the influence of human activities, the eutrophication of water bodies has increased year by year, resulting in an increasing trend of hypoxia in the bottom water bodies near the coast. Dissolved oxygen in the ocean is an important biogenic factor parameter and a key factor for the maintenance and development of marine ecosystems. It is generally defined that the DO concentration in the water body is less than 2 mg / L as an anoxic state. When the DO concentration in the water body is more than 2 mg / L, it is an anoxic state, and most aquatic organisms in the ocean will face death.[0003]Water hypoxia seriously harms the estuary and offshore environment. Hypoxia events will reduce the diversity of marine species, change the community structure of marine life, and reduce ...
