Description

The cultural method of culturing pool closed cycle

Technical field the present invention relates to aquaculture, says it is a kind of cultural method that fish, shrimp etc. are cultured the water realization closed cycle in pond of culturing in detail.

We know background technology, aquaculture requires to have reliable life-support system, this just requires to culture the pond water and accurately controls a series of indexs such as ammonia nitrogen amount, dissolved oxygen amount, acid-base value, for satisfying these indexs, the culture fishery of China adopts the cultural method of pond water open loop to culture material cultures such as fish, shrimp always, Here it is constantly supplies water to culturing the pond from natural world, and the water of culturing in the pond constantly discharges to natural world again.The cultural method of this pond water open loop, ammonia, nitrogen, carbon dioxide content height, dissolved oxygen amount is low, acid-base value can not obtain balance, and water temperature is wayward, and particularly winter is more wayward, and material culture incidence of disease height such as fish, shrimp, have a strong impact on the growth of material cultures such as fish, shrimp, of poor benefits, Chi Shui discharging the Nature contaminated environment.

The technical problem that summary of the invention the present invention solves is, solve ammonia, nitrogen, carbon dioxide content height in the water open loop cultural method of pond, dissolved oxygen amount is low, acid-base value can not obtain balance, water temperature is wayward, particularly winter is more wayward, and material culture incidence of disease height such as fish, shrimp, have a strong impact on the growth of material cultures such as fish, shrimp, of poor benefits, Chi Shui discharging the Nature problem of environment pollution caused, provide a kind of ammonia, nitrogen content low, the dissolved oxygen amount height, ph balancing water stabilization, the cultural method of the culturing pool closed cycle of water temperature balance.

Technical scheme of the present invention is, Chi Shui sends into Microfilter through siphon pipe, Microfilter is with residual bait, ight soil is separated before hydrolysis, Chi Shui enters tank after Microfilter filters, pump into filter through water pump again, add the disinfectant sterilization that carries out disinfection simultaneously, filter is divided into three grades of filter chambers, the one-level filter chamber is the sandstone filter chamber, and the secondary filter chamber is biological filter chamber, and three grades of filter chambers are the activated carbon filter chamber, through entering preheating vapour floating chamber after the filter filtering, vapour floats temperature adjustment, enter the breed pond after removing impurity, when entering the breed pond, charge into oxygen, become the dissolved oxygen water of high concentration.

Organic matters such as the invention has the beneficial effects as follows can filtering ammonia, nitrogen are removed metal ions such as iron, manganese, and the Balancing degree can provide high concentration dissolved oxygen water; The circulatory system of sealing can provide stable water quality and balancing water temperature, reduces the incidence of disease of material cultures such as fish, shrimp, improves survival rate and growth rate, increases economic benefit, also can not pollute natural environment simultaneously.The present invention can a plurality of breed arranged side by side pond.The present invention is applicable to culture fishery.

Appended drawings is a kind of method flow schematic diagram of the present invention, also is a kind of method flow schematic diagram of embodiment.

The cultural method of embodiment culturing pool closed cycle as shown in the figure, the Chi Shui that cultures pond 5 enters collecting basin 6 through siphon pipe 4, outlet valve 2, the discharge that outlet valve 2 can regulating reservoir water.Siphon pipe 4 lower ends are provided with exhaust-valve 7, can carry out work such as blowdown, sterilization, maintenance by emptying Chi Shui.After Chi Shui enters collecting basin 6, enter Microfilter 12 through outlet pipe 8, Microfilter 12 is separated residual bait, ight soil before hydrolysis.Chi Shui enters tank 11 and pumps into filter 17 through water pump 18 again after Microfilter 12 filters, add the disinfectant sterilization that carries out disinfection simultaneously.Disinfectant is an ozone, and ozone is strong oxidizer, and sterilizing speed is fast, and metal ions such as simultaneous oxidation iron, manganese become high price iron, manganese, and ozone decomposes fast and generates oxygen, increases the water body dissolved oxygen amount.Ozone is supplied with by ozone generator 19, and ozone generator 19 connects air compressor machine 10 and oxygenerator 9 makes it air supply and oxygen.Disinfectant also can be ultraviolet ray, perhaps medicament, as: bleaching powder, formaldehyde, chlorine, chlorine dioxide, clorox, the tincture of iodine, iodine fluorine etc., these all are that sterilizing institute generally adopts in the light water treatment technology, no longer detailed description.Filter 17 is divided into three grades of filter chambers, and the one-level filter chamber is the sandstone filter chamber, is provided with the sandstone filtering layer in the sandstone filter chamber, can remove solid content, impurity such as flocculate, high price iron, manganese; The secondary filter chamber is biological filter chamber, be provided with biological ball in the biological filter chamber, grow on the biological ball bacterial digestion or photosynthetic bacteria, can digest organic matters such as ammonia in the elimination water, nitrogen, on the biological ball floras such as actinomycetes, lactic acid bacteria, saccharomycete can also be arranged, these all be in the biological ball of selling in the market the profitable strain that generally adopts, no longer describe in detail; Three grades of filter chambers are the activated carbon filter chamber, and the activated carbon filter chamber is provided with the activated carbon filtering layer, can effectively adsorb organic matters such as residual ozone, ammonia, nitrogen, remove metal ion such as iron, manganese and peculiar smell etc.Through behind the filter 17, enter preheating vapour floating chamber 13, water temperature can be improved, be regulated in preheating vapour floating chamber 13, because water temperature improves, floating foreign material such as the oil in the water, flocculate and organic matters such as ammonia, nitrogen can be bubbled through the water column and decompose the vaporization eliminating.Preheating vapour floating chamber 13 inserts heat exchanger 14, and heat exchanger 14 inserts hot water valve 16 and feeds hot water or steam, is

heat exchanger

14 and 13 heat supplies of preheating vapour floating chamber, balancing water temperature.Insert water compensating valve 15 in the preheating vapour floating chamber 13, can supply culture pond 5 because the Chi Shui of losses such as the consumption of material cultures such as fish, shrimp, evaporation, water compensating valve 15 also can be located at filter 17 front ends, with the filtering make-up water.Chi Shui enters breed pond 5 through water inlet pipe 1, water intaking valve 3 behind preheating vapour floating chamber 13, water intaking valve 3 can be regulated inflow.When entering breed pond 5, charge into oxygen, become the dissolved oxygen water of high concentration.Oxygen provides pure oxygen more than 95% by oxygenerator 9, and the air of oxygenerator 9 is supplied with by air compressor machine 10, and the quantity delivered of oxygen is regulated by dissolved oxygen adjuster 20.The cultural method of culturing pool closed cycle can balancing water temperature, and stabilizing water quality can provide high-quality ecotope for material cultures such as fish, shrimps, can reduce the incidence of disease, improve survival rate and growth rate, increase output, the circulatory system of sealing can not polluted natural environment yet.As can be seen from the figure, the present invention can a plurality of breed arranged side by side pond 5.
