Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Embodiment: Fig. 1 is a kind of extra large, freshwater aquiculture tail water processing qualified discharge, reclaiming system disclosed by the invention, including
Dephosphorization water tank 1, film slot 3, filter 4 and small molecule sterilizer 20.Cultivation tail water in crawl is first pumped into dephosphorization water tank 1
Storage has metal electrode board 5(such as magnesium plate, iron plate, the aluminium sheet of logical direct current in dephosphorization water tank 1), direct current pair in the seawater
The anode electrolysis such as magnesium, aluminium, iron generate positive metal ions, react with phosphate radical and generate phosphoric acid salt settling, reach dephosphorization purpose calmly,
These sedimentation phosphate are filtered out by refined filtration.
As shown in Figure 1, dephosphorization water tank 1 is connect by the first water pipe 7 with filter 4, elevator pump is installed on the first water pipe 7
2.Filter 4 is connect by the second water pipe 8 with film slot 3, and film slot 3 is connect by third water pipe 9 with filter 4, third water
Pipe 9 connects on the first water pipe 7, and the water in third water pipe 9 also passes through elevator pump 2.Filter structure 6, filtering knot are equipped in filter 4
Structure 6 includes several filter cores 61, and filter core 61 is equipped with filter cloth 612(and sees Fig. 2).
The aqueous of containing diatomite in the pumping film slot 3 of third water pipe 9 is first passed through before filtering by filter core 61, and diatomite is made to exist
612 outer surface of filter cloth forms coating, and the draining of filter 4 is back to film slot 3 by the second water pipe 8；Pass through first when filtering
Water pipe 7 pumps in dephosphorization water tank 1 cultivation tail water by filter cloth 612, the coating on filter cloth 612 make to cultivate suspended matter in tail water,
The pollutants such as greasy dirt do not contact directly with filter cloth 612, ensure that the long-time service of filter cloth 612, solve general accurate filter
The problems such as the filtering layer encountered when operation easily blocks, difficult backwash, service life are short, are a quantum jumps of filtering technique.
As shown in Figure 1,612 inner cavity of filter cloth connects the 4th water pipe 10, the 4th water pipe 10 leads to small molecule sterilizer 20.Filtering
4 bottom of machine is equipped with discharge gate 14 and discharge outlet 15, and discharge outlet 15 connects dephosphorization water tank 1 by the 5th water pipe 11.4th water pipe
10 also connect with the second water pipe 8, are equipped with the first valve 12 on the 4th water pipe 10, the second valve 13 is equipped on the second water pipe 8.
The first tracheae 16 is connected on the 4th water pipe 10 between filter 4 and the first valve 12, between filter 4 and the second valve 13
The second water pipe 8 on be connected with the second tracheae 17.It is mounted on pressure reducing valve 18 on first tracheae 16 and the second tracheae 17, and is connected
Connect air pressure pump 19.
It is sterilized as shown in Figure 1, being drained into small molecule sterilizer 20 through the filtered water of filtration core 61 by the 4th water pipe 10,
612 outer surface solid slag of filter cloth is more after a period of work for filter core 61, needs scarfing cinder.The inlet valve of filter 4 is closed when scarfing cinder
Door, simultaneously closes off the first valve 12 and the second valve 13, the compressed air of air pressure pump 19 is blown into filter 4, utilizes
Pressure reducing valve 18 turns air pressure (being unlikely to blow down the solid slag on filter cloth 612) down, and the water in filter 4 cannot pass through 61 row of filter core at this time
Out, dephosphorization water tank 1 can only be drained into from the 5th water pipe 11, to empty the water in filter 4；Then it opens the second valve 13, close
The valve on the 5th water pipe 11 is closed, compressed air makes the steam in diatomite layer and solid slag layer on 612 outer surface of filter cloth from
Two water pipes 8 drain into film slot 3, reduce diatomite layer and the water content of solid slag layer and desiccation agglomeration；Finally close the second valve
Door 13 opens discharge gate 14, tunes up the air pressure of compressed air, and the solid slag on filter cloth 612 is blown off and from deslagging by compressed air
Gate 14 is discharged.
In conjunction with Fig. 2 and Fig. 4, filter core 61 is by filter cloth 612, outer sleeve 611, inner tube 613, capping sleeve 615 and 614 groups of back cover sleeve
At tubular filter cloth 612 is coated on outer sleeve 611, and inner tube 613 is through in outer sleeve 611, and 613 side of inner tube is uniformly set
There are several discharge orifice 613a.
As shown in figure 3, the both ends of outer sleeve 611 communicate and connect respectively with back cover sleeve 614, capping sleeve 615, back cover sleeve

Technological transformation to traditional cultivating system, has pushed the structural adjustment of seawater, Fish-water Fish Farming industry.
Utilize above-mentioned sea, the purification method of freshwater aquiculture tail water processing qualified discharge, reclaiming system are as follows:
The first step, electrolytic metal anode dephosphorization (Magnesium Ammonium Phosphate, ferrous phosphate, aluminum phosphate sedimentation), bait, fish excrement in breeding seawater
So that water body is contained higher concentration phosphate (being dissolved in tail water), has very big harm to fish body growth, pole needs to remove, and utilizes phosphamide
The mechanism of the metals salt settling such as magnesium, ferrous phosphate, aluminum phosphate in the seawater generates the anode electrolysis such as magnesium, iron, aluminium with direct current
Positive metal ions react with phosphate radical and generate phosphoric acid salt settling, to achieve the purpose that dephosphorization, then filter out these by refined filtration and sink
Phosphate drops；
Second step, film pump the mixed liquor (diatomite is mixed with water) in film slot 3 by filter cloth 612, until being discharged limpid
Until (film finishes)；
Third step, filtering, the cultivation tail water pumped in dephosphorization water tank 1 pass through filter cloth 612；
4th step, scarfing cinder, after system runs a period of time, when the 4th water pipe 10 becomes smaller to 20 water flow of small molecule sterilizer,
Illustrate that filter cloth 612 blocks, close the water pump pumped to filter 4, close the first valve 12 and the second valve 13, opens air pressure
Contracting pump 19 is using in compressed air emptying filter 4；Then it opens the second valve 13, close the valve on the 5th water pipe 11
Door, compressed air make the steam in diatomite layer and solid slag layer on 612 outer surface of filter cloth drain into film slot 3 from the second water pipe 8
It is interior, reduce diatomite layer and the water content of solid slag layer and desiccation agglomeration；It finally closes the second valve 13, open discharge gate
14, blown out of filter core 61 to outside filter cloth 612 using compressed air, by the solid slag on filter cloth 612 be blown to it is blocking fall off, and from row
Slag gate 14 is discharged；
5th step, sterilization, is pumped into small molecule sterilizer 20 for the water in the 4th water pipe 10 and sterilizes, the water after sterilization is discharged into crawl
In.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
