Description
Technical field
The present invention relates to device that the water quality in culture environment of aquatic products or the Shui nationality product is handled, especially relate to a kind of grains of sand bed biofiltration device that is used for aquaculture.
Background technology
Circulating water cultivation is the mode with water treatment, and the water quality of control water body makes biological production smooth; Significantly reduce simultaneously water-flowing type aquaculture or sealing formula and culture the disappearance that often to change water in a large number; Especially indoor circulation water cultivating system, hope can be got rid of the pollution of external new water, solves pathogen infection and spreads; In addition, circulating water cultivation has following several requirements:
1. keep stable water quality, make the aquaculture organism can be well-adjusted;
2. improve aquatic biological survival rate and rate of growth, reduce aquaculture cost, increase and culture income;
3. reduce the waste of labour and water resource;
4. increase land utilization rate;
5. reduce the organic contamination of discharge water, reduce impact environment;
6. reduce the propagation of cause of disease and the impact of medicament residue.
In aquaculture and the Shui nationality industry, because the excremental accumulation of material culture, the corruption of the excessive food of throwing something and feeding causes the continuous variation of water quality meeting of culturing in pond or the aquarium; Dissolved oxygen amount reduces, and produces nitrous acid, and influences the healthy growth of material culture; In order to keep the health of breeding environment water quality, traditional way is to change water, yet; Because it is all very big usually to culture the volume in pond, and water is changed in the breed pond of big volume, will cause a large amount of wastes of water resource; Not environmental protection, and change in the water process, all inevasible meeting of the material culture in whole breed pond and the aquarium is alarmed; Might cause the dead or injured of a small amount of material culture, special in some comparatively enervated material culture, change water and probably bring the part material culture dead.
Summary of the invention
The problem that the present invention will solve provides a kind of simple in structure, connection and reasonable arrangement, it is effective to dispose of sewage, practice thrift cost, the grains of sand bed biofiltration device that is used for aquaculture easy to maintenance, especially is suitable for use in the breed pond of aquaculture.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of grains of sand bed biofiltration device that is used for aquaculture comprises filtering container, first screen pack, second screen pack, sparge pipe; The surface of said filtering container and bottom are equipped with some through holes, and the appearance bread of said filtering container is provided with second screen pack, are provided with first screen pack in the said filtering container, in said first screen pack medium are housed; Said sparge pipe is plugged in first screen pack that medium is housed, and the bottom of said sparge pipe contacts with the bottom surface of said first screen pack; The part that is inserted into medium of said sparge pipe is provided with some inlet openings, the bottom sealing of said sparge pipe, and the upper end is provided with the duckbill delivery port to lopsidedness; The end of said first screen pack and second screen pack all is fixed on the said sparge pipe, on the sparge pipe of outstanding said filtering container, is provided with air inlet pipe.
Fill medium in said first screen pack, and the inlet opening of sparge pipe all is immersed in the medium, prevent gas leakage; The end of said first screen pack and second screen pack is fixed on the said sparge pipe through rope.
Preferably, the diameter of said through hole is 1cm.
Said filtering container needs intensive punching.
Preferably, said first screen pack is 90 order nylon wires, and said second screen pack is 60 order nylon wires.
Preferably, said medium is served as reasons and is comprised the mixture that sand and active carbon are formed, and the volume ratio of said sand and active carbon is 1: 1.
Preferably, said Fungicidal substance is served as reasons and is comprised the mixture that sand, active carbon, stone are formed, and its three's volume ratio is 1: 1: 1, and the granularity of said stone is 0.2-0.3cm.
Said stone is a size as the mung bean.
Preferably, said filtering container is plastic containers, and its bottom surface girth is 30cm, and height is 60cm.
Preferably, said sparge pipe is plugged in the midway of first screen pack that medium is housed.
Preferably, said sparge pipe is three to be in charge of, and the diameter of its inlet opening is 0.6cm.
The about 80cm of said sparge pipe is long, and length need be looked the water depth increase and decrease.
Preferably, on the sparge pipe at outstanding said filtering container 4cm place, be provided with air inlet pipe, said air inlet pipe is provided with water yield by-pass cock.
Said granularity refers to the size of particle, and the measurement of granularity comes down to through what compare the ball of measured particle and commaterial formation, and the granularity of spherical particles representes that with diameter the granularity of cubic granules is represented with the length of side usually.To irregular mineral grain, can be with the equivalent diameter of a certain sphere diameter of identical behavior as this particle being arranged with mineral grain, stone of the present invention is an irregular particle.
When use is of the present invention, the present invention is placed on the pool side edge of culturing the pond, delivery port is 3cm apart from the water surface distance of culturing the pond, puts in a clockwise direction; Every interval is placed one group for one meter, by fan blower air is squeezed in the sparge pipe through air inlet pipe, will import the duckbill delivery port at sparge pipe top through behind the inner flowing water filtration, purification of these grains of sand bed biofiltration device; With the water ejection, thus, not only can drive the water clockwise direction and flow, increase dissolved oxygen amount; And the water in purifying aquaculture pond, keep water stabilization, reduce sewage discharge; Using water wisely, even non discharge sewage, and then reach carbon reduction.
The revolution of said fan blower is 2840 rev/mins.
Said medium comprises sand, active carbon, stone, because the particle of sand and stone is smaller, its specific surface area is bigger, and the microbial biomass that adheres to is bigger, and biologically active is higher, the water treatment better effects if.
Medium in the present invention can regularly clean once in use for some time, strengthens the function that water purifies.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, grains of sand bed biofiltration device is placed on cultures in the pond, the pollutant in the breed pond contacts with the beneficial microbe film on the biofilter; Reach the effect of purification; Thereby guarantee the stable of water quality, need not often to change water, practice thrift cost; The material culture survival rate improves 20%, makes aquaculture convenient; Have simple in structure, high efficiency, low, the income advantages of higher of cost.
