The technical solution adopted for the present invention to solve the technical problems is to provide a kind of shrimp culture tail water circulation process method, comprise: above the filtering basin of the water outlet passages downstream of shrimp culture canopy, screen cloth is set, precipitated in settling tank by the cultivation tail water of screen cloth, cultivation tail water after precipitation introduces stream, microorganism and plant purification in stream, lead back cultivation water reservoir again by breeding water.
Keep flat brickbat in a jumble bottom described stream, brickbat covers bottom stream, forms the microbially decontaminate district that surface-area is larger.
Plant reed and water peanut in described stream, wherein water peanut covers water surface area 20-50%.
The flow velocity in described stream controls as 100-200 m/h.
Another technical problem to be solved by this invention is to provide a kind of shrimp culture tail water cyclic processing device, and this device can realize above-mentioned shrimp culture tail water circulation process method.
The present invention solves the technical scheme that this technical problem adopts and is to provide a kind of shrimp culture tail water cyclic processing device, comprise shrimp culture canopy, filtering basin, settling tank, stream and cultivation water reservoir, described shrimp culture canopy, filtering basin, settling tank, stream circulate successively with cultivation water reservoir and are communicated with, the top of described filtering basin arranges screen cloth, the water exit of described shrimp culture canopy is arranged on above the screen cloth of filtering basin, and the water outlet of described settling tank is arranged on the top of settling tank.
Described screen slope is arranged on above filtering basin.
The shorter side of described filtering basin arranges solid substance groove, and solid substance groove has constant slope, arranges a solid substance collector below the discharge port of solid substance groove.
Described screen cloth selects removal 70% ~ 80% to cultivate the aperture of the residual bait in tail water.
Leave unused stream in selection rural area, described stream.
Described stream selects length to be greater than 3 kilometers, width 1-3 rice, depth of water 0.5-1 rice.
Beneficial effect
The circulation process method of shrimp culture tail water provided by the invention, the stage purification mode precipitating microorganism in little solid substance, stream and plant purification soluble organic by the large solid substance of screen filtration, settling tank realizes the environmental protection treatment to cultivation tail water, make use of the detergent power in stream simultaneously, reduce the cost of tail water process, improve decontamination effect improving.Device provided by the present invention is water circle device, and the breeding water after purification can carry out recycle.Screen cloth and solid substance groove can be arranged to inclination, and the large solid substance being filtered out landing also can finally enter solid substance collector voluntarily, and solid substance can carry out refuse reclamation through process.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of apparatus of the present invention.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
A kind of device realizing shrimp culture tail water circulation process method as shown in Figure 1, comprise shrimp culture canopy 1, filtering basin 3, settling tank 4, stream 5 and cultivation water reservoir 7, these form the connection that circulates successively, the top of filtering basin 3 arranges screen cloth 2, the water exit of shrimp culture canopy 1 is arranged on above the screen cloth 2 of filtering basin 3, and the water outlet of settling tank 4 is arranged on the top of settling tank 4.
Described screen cloth 2 is inclined at above filtering basin 3.
The shorter side of described filtering basin 3 arranges solid substance groove 6, and solid substance groove 6 has constant slope, arranges a solid substance collector 8 below the discharge port of solid substance groove 6.
Suitable aperture selected by described screen cloth 2, can remove the residual bait of in cultivation tail water 70% ~ 80%.
Described stream 5 selects rural area to leave unused stream.
Described stream 5 selects length to be greater than 3 kilometers, width 1-3 rice, depth of water 0.5-1 rice.
Keep flat brickbat in a jumble bottom described stream 5, brickbat covers bottom stream, forms the microbially decontaminate district that surface-area is larger.
Plantation reed and water peanut in described stream 5, wherein water peanut covers water surface area 20-50%.
The flow velocity in described stream 5 controls as 100-200 m/h.
Cultivation tail water is released from the water outlet passage of shrimp culture canopy 1, and flow to the top of screen cloth 2, the filtration through screen cloth 2 enters into filtering basin 3.Wherein, the solid substance filtered out can be slipped in solid substance groove 6 voluntarily, solid substance in solid substance groove 6 can be slipped to again in the solid substance collector 8 below discharge port voluntarily, can carry out refuse reclamation after treatment, carries out the cultivation of culturing pool microalgae as being used for after fermentation.The residual bait of 70% ~ 80% and some other large solid substance has been eliminated in the tail water obtained like this, again through the precipitating action of settling tank 4, the little solid substance sedimentation that filtered removes descended further, now the tail water of settling tank 4 middle and upper part is still containing more dissolved organic matter.Again the tail water after precipitation is incorporated into idle stream, rural area from the top water outlet of settling tank 4, slowly flows through the stream being about 3000Km.Keep flat brickbat in a jumble bottom stream, brickbat covers bottom stream, forms the microbially decontaminate district that surface-area is larger; Plant reed and water peanut in stream, wherein the water surface fraction of coverage of water peanut is 20-50%, has the effect of good middle dissolved organic matter of purifying waste water.Now, control flow velocity is 100-200 m/h, under the external environment of 15-30 DEG C, microorganism in stream and the cleaning action of pasture and water, when tail water flows through stream end, the COD in water can be made to drop to below 25mg/kg, treated tail water can be led back again cultivation poultry pond 7 and reuse through simple process.
