Abstract
The invention relates to the technical field of aquaculture pond water quality ecological regulation, and provides a fishery machine used for promoting sufficient exchange of upper and lower bottom water in a culture pond. The machine comprises a submersible pump, a water delivery pipe, a cylindrical float, a spraying head, and the like. When working is started, the submersible pump draws bottom layer water and silt flocs, and the bottom layer water and silt flocs are sprayed through the spraying head and fall onto the water surface, such that upper and lower bottom water can be sufficiently exchanged. Through promoting the sufficient exchange of the upper and lower bottom water of the pond, phenomena of upper and lower water temperature stratification, upper and lower dissolved oxygen stratification and upper and lower pH stratification are broken through; a situation of lower bottom dissolved oxygen deficiency is ameliorated; water upper and lower pH values are kept balanced and stable; and accumulation of harmful substances such as nitrite, hydrogen sulfide, ammonia, methane and the like is effectively reduced. Also, pond bottom silt resuspension and re-release are promoted, such that rich nutrients and rich microbial populations in the sediment are released into water; algal and bacterial phase scientific management is facilitated; and pond ecological environment self-purification capacity is greatly improved.
Description
Technical field
The invention belongs to water quality of aquaculture pond ecology regulation and control technical field, be specifically related to a kind of fishery machinery that the upper and lower bottom water body of cultivating pool fully exchanges that promotes.
Background technology
At the high temperature season of aquaculture, on particularly sunny daytime, due to lower leaf on the pond waters of water temperature formation, clearly, TNE UPPER SEA TEMPERATURE high specific gravity is little, light, and lower floor's water temperature low-gravity is large, heavy, is difficult to break under this lamination natural situation.This upper and lower lamination, is not only water temperature delamination, and causes dissolved oxygen layering, pH layering and even water body materials stratify etc., and these layerings become a large obstacle of pond ecosystem normal operation circulation, so must break.
1, lower leaf on dissolved oxygen.The main source of pond dissolved oxygen, comes from the photosynthesis of algae, general accounting 70 ~ 80%.Algae is generally distributed in the illumination layer of epiliminion, and photosynthesis constantly produces oxygen, and under fair weather, upper epidermis dissolved oxygen reaches capacity state very soon, the above state of afternoon the dissolved oxygen even twice of degree of reaching capacity.
Due to water temperature delamination phenomenon, upper and lower bottom is difficult to exchange, and the oversaturated dissolved oxygen of upper epidermis can not exchange lower bottom in time and escape in air, causes dissolved oxygen to waste, and forms pond " oxygen debt ".And the lower bottom being in oxygen consumption state can not get oxygen replenishment, all the time anoxic reducing state is in, this will directly hinder the optimum running of pond ecosystem material, in substance decomposition metabolic process, certainly will cause the accumulation of the harmful substances such as nitrite, hydrogen sulphide, ammonia, methane.And under being in anoxia condition for a long time, a large amount of opportunists will be grown, as the raised growth of the amphimicrobian pathogenic microorganisms such as Aeromonas hydrophila, vibrios, streptococcus.
2, the upper lower leaf of pH.Due to the number of the upper and lower water layer distribution of algae, photosynthesis and respiration have notable difference at upper and lower bottom, directly results in the height change of the upper and lower bottom pH of cultivating pool.
Please see that (this is CO in pond water chemistry to following convenient type
3 2----HCO
3 ----CO
2buffer system detaches easy equation out):
Find out from this convenient type, when pond algae breeds rapidly, CO in the vigorous quick consumption water of photosynthesis
2, impel convenient type to balance and move right, accumulate OH in a large number in result water, pH raises.This situation mostly occurs at the epiliminion of fair weather.
And bottom photosynthesis is very weak under pond, contrary respiration (aquatic respiration, bed mud are breathed) dominate, respiration is all oxygen consumption and releases CO
2, in water body, accumulate CO in a large number
2, impel above-mentioned balance to be moved to the left, OH
-reduce, pH declines.
Upper epidermis illumination is strong, and photosynthesis is strong, and algae proliferation is vigorous, and pH is high.Because the strong and weak difference of day and night photosynthesis is very large, so upper water pH day and night fluctuation amplitude is very large.In the afternoon of fair weather, pH usually reaches more than 9; And pond bottom, no matter daytime or night respiration effect are in leading position always, so bottom water pH is low and fluctuating range round the clock is very little.Some can not do the pond of pool desilting for a long time, and the thick sedimentary organic material of mud is many, is often in anaerobic digestion, can generate a large amount of organic acid, cause pH to be down to less than 5.
PH is the very important chemistry of pond waters and ecological factor, and too high and too low all have very large adverse effect to water quality and biology, strengthens cultivated animals toxicity.
3, lower leaf on water body material.Or because algae is distributed in the illumination layer of upper epidermis more, due to photosynthesis, algae increment is vigorous and consume a large number of nutrients, cause the local of upper epidermis nutriment deficient.Due to the layering of upper and lower water temperature, upper and lower bottom is difficult to exchange, and is in a large amount of nutriment of middle lower floor water body and is called the activated sludge of pond " nutrition library ", be difficult to add to upper epidermis in time.
Like high water temperature, intense light irradiation like this, blue-green algae that high pH is in upper epidermis, inherently there is the competitive advantage absorbing nutriment between algal populations, due to the scarcity of upper epidermis nutriment, easily form the single dominant population of blue-green algae, suppress the Growth and reproduction of other algae.Often cultivate season at aquatic products high temperature, cause strong single blue-green alga bloom, then occur " algae " phenomenon of blue-green algae mortality.This blue-green alga bloom and " algae " phenomenon thereof, have very large destructive power to pond ecosystem, cause great puzzlement to regulating and controlling water quality.
In sum, aquatic products high temperature cultivation season, sunny afternoon, people was for breaking upper and lower water temperature delamination, and impelling upper and lower bottom fully to exchange, will be the very important control measures maintaining the optimum running of pond ecosystem and Scientific Regulation water quality.
For a long time due to drawback that upper and lower water temperature delamination phenomenon is caused and seriousness understanding not enough, the fishery machinery product that upper lower leaf is broken in development lacks always.Present cultivation noon in season, only opens vane type or these common aerators of Waterwheel-type to break upper and lower lamination.Due to vane type or waterwheel aerator, comprising these fishery machineries such as the swell type aerator newly put goods on the market in recent years is all stir at upper epiliminion to dig current, be difficult to accomplish lower layer of water especially bottom water fully exchange with upper water.
By the use of this multi-functional upper and lower water layer AC machine of the present invention, the abundant interchange of the upper and lower bottom of effective promotion water body, be not only the layering etc. of breaking upper and lower water temperature delamination, dissolved oxygen layering up and down, up and down pH, impel the settling flux of mud batt layer at the bottom of pond to discharge again especially.To thoroughly improve the ecotope of whole pond waters, be conducive to running good between the circulation of pond ecological surrounding material and biotic population, increase substantially the self-detergent power of pond waters.
