Description
Technical field
The present invention relates to oxygen increasing equipment technical field more particularly to a kind of wind wheel type aerators.
Background technique
Pond waters oxygenation way mainly has the several ways such as chemical enhancement, mechanical enhancement, biological enhancementoxygen.Chemical enhancement master
If artificially launching some chemicals into breeding water body, chemical action release oxygen occurs in water after meeting water, thus
The content of dissolved oxygen in water body is improved, chemical enhancement agent is generally sodium carbonate peroxide, superamide, calper calcium peroxide, hydrogen peroxide
Any one of with peroxo disulfate ammonium.Mechanical enhancement mainly passes through fishery machinery and provides content high water body into breeding water body
Or water body effectively contact with air to water body oxygen is continuously replenished by way of increase the dissolved oxygen in water body.Biological enhancementoxygen
Refer to and is planted in suitable water plant or artificial increase water body in the culture pond mouth (such as freshwater shrimp, river crab, fish) for preferably transplanting water plant
Phytoplankton the carbon dioxide in water body is absorbed by the photosynthesis of water plant and phytoplankton, discharge oxygen to reach
The purpose of water oxygenation.
Wind wheel type aerator is the most widely used one kind in mechanical enhancement mode in recent years.Impeller rotates when work,
Water body is stirred, spray, and the centrifugal force generated by rotation is generated, spreads upper water column to periphery, lower water column fills a vacancy to be formed
Water body recycles up and down.After the higher superficial water of oxygen content enters bottom, it is effectively improved the dissolved oxygen situation of bottom water body.But tradition makes
The oxygenation efficiency of wind wheel type aerator is lower, and water body is only capable of reaching oxygenation and being raised by impeller with air enlarged contact
Purpose, the oxygen dissolved in water body is limited, it is difficult to meet the needs of pond culture volume increase, still be easy to appear high yield and raise the nose above water to breathe to lack
Oxygen and cause fish mortality.
