Embodiment: referring to figs. 1 through Fig. 2, the industrialized culture water circle device is applied to the industrialized culture water circle device, and this device has the into breed pond 1 of water and water-freeing arrangement, wherein: culture pond 1 water-freeing arrangement and be connected with biochemistry pool 3 through solid-liquid separator 2; Biochemistry pool 3 also is connected with diversion three-way valve 4; The direct pipe connection backflow of a path T-valve 8 of diversion three-way valve 4 also is back to breed pond 1; Another path of diversion three-way valve 4 then connects backflow T-valve 8 except that the ozone water treatment system of residual ozone in anhydrating and strong oxide compound as required through carrying out the supersaturation ozonization to breed water.
Ozone water treatment system has the ozone solution that ozone and water are fully contacted be water that is connected with diversion three-way valve 4 and reaches oversaturated oxidizing tower 5; Oxidizing tower 5 is gone back pipe connection has reduction tower 6; Reduction tower 6 is through being equipped with the pipe connection backflow T-valve 8 of detector 7.
Oxidizing tower 5 is connected with ozonizer 51; Reduction tower 6 is connected with pneumatic pump 63; Detector 7 is connected with power controller 71; Ozonizer 51 connects power controller 71.Ozone reduction tower 6 comprises the tank body 61 of hollow cavity, and wherein: the middle part of tank body 61 inner chambers is provided with protruded packing 614; Be provided with spray header 615 near the top of tank body 61 inner chambers; The bottom of tank body 61 inner chambers is provided with micropore air-spreading disk 619; Near tank body 61 bottoms side is run through and is provided with water outlet 616.External water source sprays into tank body 61 inside through spray header 615, and the micropore air-spreading disk 619 that is positioned at tank body 61 bottoms connects external air source.Source of the gas is air or reducing gas.The water of gas and the external water source of ejection is sentenced big surface in contact at protruded packing 614 and is amassed mode and mix, and neutralizes and removes the material with oxidisability in the external water source water.Water after the processing is discharged from water outlet 616.Tank body 61 bottoms have blow-off pipe 61a; Tank body 61 tops also have exhaust port 612.Exhaust port 612 is discharged unnecessary gas, and balance tank body 61 pressure inside, and the acquisition environment of stable liquid level sensor 621 reduces and disturbs.Tank body has riser 613 near 61 tops.Riser 613 is a security measures, when malfunctioning situation appears in system, is the danger that prevents that too high water level from causing, thereby design riser 613 is discharged unnecessary water.
Tank body 61 bottoms are attached with liquid level sensor 621.The liquid level sensor 621 of bottom can be according to the flow velocity of the control of the liquid level change in the tank body 61 external water source to spray header 615 water fillings.The bottom also has supporting leg 61b.
Tank body 61 sides are equipped with liquidometer 622.Liquidometer 622 supplies the personal monitoring.Micropore air-spreading disk 619 can connect external air source through gas meter 624; Spray header 615 can connect external water source through liquid meter 623.Gas meter 624, liquid meter 623, liquid level sensor 621 are regulated and control the speed of air inlet, water inlet through the coupling of detection data.Tank body 61 tops are shaped on top manhole 611; Tank body 61 sides are shaped at least one side manhole 618; Bottom, tank body 61 side is run through and is provided with visor 617.
Culture pond 1 and in breeding process, can produce a large amount of objectionable impuritiess, batch production particularly superset spend in the cultivating system, approximately for the very big after the meeting toxic action of cultured fishes.Therefore effectively remove these materials, have realistic meaning for reducing the breeding wastewater discharging.The waste water of culturing pond 1 is through removing solid waste earlier through solid-liquid separator 2, again through biochemistry pool 3 with the remaining dissolved organic matter of biological mode rough handling, ammonia nitrogen, nitrous acid nitrogen.The water of handling through biochemistry pool 3 is divided into two paths as required through diversion three-way valve 4.Wherein an elder generation is through oxidizing tower 5; Oxygen in the oxygen canister 52 forms a large amount of ozone and injects oxidizing tower 5 and mix with the abundant aeration of water after ozonizer 51 is handled; Make the ozone in the water reach hypersaturated state; With all oxidations such as dissolved organic matter, ammonia nitrogen, nitrous acid nitrogen,, and attach the effect of having played kill microorganisms with this with reduced toxicity.Yet, because a large amount of injections of ozone, but injected new toxic substance removing the toxic while of organism, in this process like ozone, bromic acid etc.Just can be reused for breed after must these materials being removed.Water after oxidizing tower 5 is handled is transported in the reduction tower 6.The bottom of tank body 61 inner chambers is provided with micropore air-spreading disk 619; Near tank body 61 bottoms side is run through and is provided with water outlet 616.External water source sprays into tank body 61 inside through spray header 615, and the micropore air-spreading disk 619 that is positioned at tank body 61 bottoms connects external air source.Source of the gas is an air.The gas of ejection is sentenced the long-pending mode of big surface in contact with water at protruded packing 614 and is mixed, and removes the material with oxidisability in anhydrating.Water after the processing is discharged into backflow T-valve 8 from water outlet 616.Detector 7 on pipeline between reduction tower 6 and the backflow T-valve 8 is with ozone in water, bromic acid content detection and feed back to power controller 71, and then the power of control ozonizer 51, and bromic acid or ozone content are higher than safety value in the water of anti-backflow.When bromic acid in the water that refluxes or ozone is too high and for a long time can not be when reducing ozonizer 51 and reduce, diversion three-way valve 4 directly is back to water through another loop and cultures pond 1 through backflow T-valve 8, poison cultured fishes to avoid materials such as bromic acid.Owing to adopt the present invention, can reduce the use of chemical water purification agent, ecological friendly, less to environmental stress.
Although combined preferred embodiment the present invention has been described; Right its is not in order to limit the present invention; Any those skilled in the art; Under the situation that does not break away from the spirit and scope of the present invention, can implement the displacement and the modification of various changes, coordinator to the theme of listing here, so protection scope of the present invention is as the criterion when looking the scope thereof that is proposed.
