The device of the utility model is described in detail with reference to embodiment.
Embodiment 1:The structure of storage pond, holding pond and circular water treating system
Device content described in the utility model includes the structure of storage pond, holding pond and two portions of structure of circular water treating system Point.
The structure of storage pond, holding pond:As shown in Figure 1, a kind of The concrete specification of storage pond, holding pond is 8m × 6m × 0.9m, pond body thickness is 15cm, surface are laid with the food grade plastic plate of blue, and temporarily foster water level control is in 40cm-50cm.Bottom, which is laid with, is connected to rectangular increasing Oxygen pipeline and refrigeration piping, storage pond, holding pond are connected by water inlet pipe and outlet pipe with circular water treating system, wherein the water of outlet pipe Efficiency of pump 470L/min, system are recycled water 30-40 times for 24 hours, separately set water pipe and connect vertical foam separator, for removing water Body protein foam.
The structure of circular water treating system:Circular water treating system is close to storage pond, holding pond, at brandreth frame up to 1m, processing System as shown in Figure 1, generally bottom surface 5m × 1m, high 1.5m cuboid PP plastic cisterns, away from setting warning at the 5cm of water tank upper end Water level drainpipe, nozzle is towards storage pond, holding pond, to prevent the loss of water body in case of harnessing the river.It is longitudinally evenly spaced with homogeneous material in system Subregion, divider height 1.3m, oral siphon are intake above subregion.It is several extremely that the packed cylindric absorption carbon of nylon wire is laid in subregion 1m, the double-deck pore blanket of covering is removing large granular impurity above the absorption carbon bag in another subregion;Intermediate subregion paving If the packed porous corallite of long strip block shape of nylon wire is several, ibid highly;Two-tube ultraviolet lamp, outlet pipe are set in the middle part of last subregion It is communicated in bottom.
Equip biomembrane:It will be fitted into bubble chamber after the porous corallite disinfection cleaning of whole bag, each bubble chamber is as one A processing unit, corallite volume account for about the 30%-40% of processing unit, and high ammonia nitrogen seawater is added, and continue fully to be aerated.It will PDN201601 bacterium solutions are uniformly splashed on porous corallite, are adjusted carbon-nitrogen ratio by 1g/L concentration addition sucrose and are promoted microorganism life It is long.Biomembrane several groups can be hung simultaneously every time as needed, ripe, the corallite net after maturation is cultivated through 4-5 days biomembranes There is mucus enrichment on bag, attachment bacterium is up to 1010Cfu/g or so, can fast degradation ammonia nitrogen.
The water body of fermentation vat is distributed according to the reasonable quantity of storage pond, holding pond, method is same as above.There is water colour in storage pond, holding pond within 3-4 days or so The case where intensification, foam increases.By tuning up breaks down proteins device, increase oxygenation, above-mentioned phenomenon disappears after 4-5 days, water ammonia Nitrogen is degradable to 2mg/L hereinafter, ammonia nitrogen degradation effect is all very notable in different storage pond, holding ponds.The King Crab that will temporarily support again is put into It is temporarily supported in storage pond, holding pond, temporarily foster daily management operation includes water quality monitoring, artificial bait throwing in, daily fishing pond, sterilizing etc. Step.
Water quality monitoring includes daily to storage pond, holding pond coolant-temperature gage, salinity, pH, dissolved oxygen, water level, ammonia nitrogen, nitrite nitrogen index It measures, indices in storage pond, holding pond is made to be maintained within normal range, is i.e. 1-4 DEG C of temperature, salinity 35-37, pH 7.5-8.5, dissolving Oxygen>5mg/L, water level 40cm-50cm, ammonia nitrogen<0.5mg/L and nitrite nitrogen<0.5mg/L.Interval feed within three days an oyster or Mussel meat, the weight during maintaining King Crab temporarily to support.The operation of fishing pond is carried out daily, and the poor King Crab of vigor is chosen, is used in combination Water pump absorbs the excreta of bottom of pond.It is sterilized with potassium permanganate after being used as the small basket single use of transfer King Crab, after drying again Secondary use.Ground is thoroughly cleaned up with fresh water after daily work.
Embodiment 2:Using effect
It is 15 tons total from the fresh and alive King Crab of Russian import on July 15th, 2017, all crabs are put down in 12 hours Respectively in the storage pond, holding pond that number is 1#-6#, single pond storage is average about at 2.5 tons.Thereafter according to market since July 20 It needs, same amount does not go out stock from each pond several times.July 16 launched B41 bacterium to 1#-6# storage pond, holding ponds, and successfully built biology Filter tank, continuous monitoring show that ammonia nitrogen can successfully degrade;August whole crab shipment on the 10th finish, this temporarily supports 26 days total.
Temporary rearing process:
After stock up, 8 points of worker daily morning carries out the work of fishing pond, pulls dead crab and the classification of half-dead crab out progress not With processing.Interval feeds a bait for 3 days, and substrate cleaning is carried out before feeding.The daily routine for carrying out water quality index Detection, including water Inversion phenomenon, dissolved oxygen, pH detection and tracking and monitoring to ammonia nitrogen, nitrite nitrogen index.July 16 is to 1#- 6# storage pond, holding ponds launch B41 bacterium, after tune up breaks down proteins device, increase pond body oxygenation.August all crab shipment on the 10th terminate.
It is as follows to temporarily supporting interpretation of result:
1, improve King Crab and fall title problem:The weight of monitoring sampling King Crab after stocking up, the results showed that King Crab weight Substantially do not change, and feed the larger fluctuation for not causing water body ammonia nitrogen, upgrowth situation is good after crab feed.
2, degradation water body ammonia nitrogen problem:After launching B41 bacterium progress biofilm into 1#-6# storage pond, holding pond water treatment systems, by 5 It or so, each pond ammonia nitrogen success are down to 2mg/L hereinafter, water nitrite nitrogen level does not vary widely from about 20mg/L.
3, extend King Crab and temporarily support matter of time:It has just stocked up a few days ago, crab is inadaptable to new environment so that at this section Between become King Crab death peak period, death toll is about daily 5 in each pond.Afterwards with temporarily foster progress, death toll There is corresponding decline, maintains daily 2 or so, every pond.By statistics, this King Crab total dead crab about 1.2 during temporarily supporting Ton, survival rate is about 92%, and survival rate is significantly improved compared to method for temporarily cultivating before.
