Description
Technical field
The present invention relates to water oxygenation technical field, particularly relate to a kind of water oxygenation technology and device thereof.
Background technology
Pond waters oxygenation way mainly contains several modes such as chemical enhancement, biological enhancementoxygen, mechanical enhancement.Chemical enhancement is mainly artificial throws in some chemicals in breeding water body, and it after meeting water, chemical action releasing oxygen occurs in water, thus improves the content of dissolved oxygen in water body, biological enhancementoxygen refers to the phytoplankton of planting appropriate pasture and water at the culture pond mouth (as freshwater shrimp, river crab, fish etc.) of pasture and water of should planting or artificially increasing in water body, by the photosynthesis of pasture and water and phytoplankton, absorb the carbonic acid gas in water body, releasing oxygen reaches the object of water oxygenation, the water body that mechanical enhancement mainly provides content high by fishery machinery in breeding water body or the dissolved oxygen increased by water body and the air mode effectively contacted to the continuous supplemental oxygen of water body in water body, mainly contain water pump, the forms such as aerator and microporous pipeline oxygenation, microporous pipeline oxygenation promotes wider oxygenation way at present, its principle is, by Roots blower, the air being rich in oxygen is sent into gas pipeline, air is sent into microporous pipe by gas pipeline, the tube wall micropore of microtubule just evenly discharges gas up and down at water body, directly pond bottom is passed to containing oxygen air, up to fall apart gas supplemental oxygen to water body from the bottom of pond.
But it is large that the shortcoming of chemical enhancement is usage amount, and recruitment is many, and cost is higher, can only be used for rescuing when fish raises the nose above water to breathe and use, should not use at the pool mouth of fry rearing, easily cause fry to occur the generation of bubble illness, and use the harm too much also easily caused fish shrimp crab; Biological enhancementoxygen easily occurs that pasture and water overgrow, and affects the transparency in pond, and pasture and water rot to float, and cause Chi Shui to worsen; The oxygenation efficiency of mechanical enhancement is lower, lower to the lifting of oxygen in water in unit interval, air utilization ratio is low, the dissolved oxygen in pond has been raised the nose above water to breathe in very difficult alleviation, and gas pipeline breakage is difficult to find afterwards, easily causes the accident, the activity of aeration facility to fish in pond has certain influence, fish is easily injured, oxygen in water can not be made to reach supersaturation, limit the oxygenation effect of unit of water body.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition improves prior art, a kind of water oxygenation technology and device thereof are provided, solve water oxygenation oxygenation efficiency in current technology low, the low state that cannot reach capacity of dissolved oxygen content, safety is low, easily cause the accident, easily to the problem that fish shrimp crab works the mischief.
For solving above technical problem, technical scheme of the present invention is:
A kind of equipment for increasing oxygen content of water, comprise oxygenation tank, it is characterized in that, described oxygenation tank is provided with hypoxemia water body entrance, the outlet of hyperoxia water body and oxygen intake, hypoxemia water body porch is connected to culturing pool by water pump, and water pump pumps water body in culturing pool in oxygenation tank, and oxygen intake is connected with pure oxygen source, oxygen enters to from oxygen intake the water body pumped with water pump in oxygenation tank and fully mixes in hyperbaric environment, and the hyperoxia water body after mixture of oxygen returns in culturing pool from hyperoxia water body outlet drain.Hypoxemia water body and purity oxygen are carried out the water-soluble solution of oxygen within the border at the high pressure sealing ring of oxygenation tank by equipment for increasing oxygen content of water of the present invention, the dissolved oxygen in water is made to reach over-saturation, hyperoxia water body is disposed in culturing pool again, thus effectively improves the oxygen content in culturing pool.Equipment for increasing oxygen content of water oxygenation efficiency of the present invention is high, safe to use, directly will be rich in the discharge into water of dissolved oxygen in culturing pool, excessive impact can not be produced, thus protection fish shrimp crab avoids it to come to harm, hyperoxia water body fully can mix with the water in culturing pool, thus improve the oxygenation uniformity of culturing pool, the dissolved oxygen be rich in hyperoxia water body also can not overflow into gaseous oxygen when mixing with the water in culturing pool, thus effectively improve whole culturing pool oxygen content, the huge machine run sound of noise is not had in culturing pool yet, what make that fish shrimp crab can be good grows, improve output.
