Processing step of the present invention is as follows:
As shown in Fig. 1 to Figure 12, first active plugboard 41 is put into rearing pool 4, according to fish size or kind situation, rearing pool 4 is separated into several and independently raises district, to carry out adult fish culture or fry cultivation;
Again fingerling is put into several raising districts to raise: each independent district that raises is along with the lengthening of sashimi (raw fish) long period, single individuality increases, required water surface area strengthens, periodically adjustment activity is needed to insert slope 41, strengthen single raising region extremely to raising marketable fish, when the marketable fish in single raising district is in sales process, single raising district, the quantity of fish is being successively decreased, active plugboard 41 reduces single raising region area gradually, strengthen the required growth water surface area of fish in adjacent single raising region, so each single raising district has gone out a collection of fish, start again to cultivate in into a collection of fingerling to corresponding single raising district at once, the circulation turnover that such fish is a collection of, fingerling in rearing pool 4 also can put several according to the water surface area of rearing pool 4 simultaneously, then often criticize and isolate single raising region with active plugboard 41, according to fish normal growth periods, the single raising region area of corresponding adjustment, also the fingerling in adjacent single raising district the mode such as can to put into according to time interval difference adjustment, feed according to oneself demand permutation and combination, rearing pool 4 is made to reach high-density breeding at full capacity, the phytoplankton that a bait part of raising district fish is cultivated by natural pond liquid and zooplankton supply, greatly reduce feeding cost, reach Ecocyclic cultivation.
Then, the water-band of cultivation rearing pool 4 excreta of bait residue and fish, process through stercoroma district 5 and suspension filtering area 6, suspension then follows current to enter into suspension filtering area 6 from lower to upper on the one hand, described suspension filtering area 6 is provided with several suspension filter beds 61, screen pack 6110 is provided with above it, screen pack 6110 is provided with filter bed cleaning device 62 below, screen pack 6110 is used for stopping that suspension flows out, make it filter, filter bed cleaning device 62 is used for scrubbing the suspension on screen pack 6110, ensure that large discharge is without blocking, clear water is passed through, suspension under then cleaning is by little poly-large, then precipitation enters stercoroma district 5, water after filtration flows out from water return pipeline 11, water treatment district 2 is flowed back to through the water return pipeline 11 be arranged on bottom rearing pool 4, form Inner eycle aquaculture model, or by greenhouse delivery port 15, water treatment district 2 is again flowed back to through external water area, form outer circulation aquaculture model, described Inner eycle aquaculture model and outer circulation aquaculture model make corresponding adjustment according to outdoor ponds waters natural environment etc., temperatures warmed in outdoor waters, when being applicable to fish normal growing conditions, then utilize outer circulation aquaculture model, when the water temperature in outdoor waters reduces, when being not suitable for fish normal growing conditions, then utilize on crawl and build roof insulating 1, adopt Inner eycle water aquaculture model.
When outer circulation water cultivates, then close water return pipeline 11, during contrary use Inner eycle water cultivation, then close greenhouse delivery port 15 and greenhouse water inlet 16, because the water of outer circulation need waters outside crawl, water circulation, after filtering through stercoroma district 5 and suspension filtering area 6, directly delivers to the waters outside crawl, after the biological self-purification such as various algae of external water area, enter water treatment district 2 by greenhouse water inlet 16; The cultivation of Inner eycle water is not owing to having extraneous natural aquatic plankton purification, water quality requirement is high, the suspension filter bed 61 of current on suspension filtering area 6, the screen pack 6110 selecting mesh larger, reduce the filtration to Organic substance in water, clear water after filtration arrives water treatment district 2 through water return pipeline 11, utilizes internal and external circulating water aquaculture model, makes its ecology fish farming facility full load in whole year amount uninterruptedly normally produce marketable fish.
The impurity precipitated on the other hand enters stercoroma district 5, and enter fish excrement biogas generating pit 13 by dredge pump 12, by the natural pond liquid after the fermentation of fish excrement biogas generating pit 13, supply and cultivate pond (not marking) to Wai Chi waters and special bait, for phytoplankton--algae, zooplankton provides desired nutritional, cultivate in pond to be provided with due to external water area and special bait and stir waterwheel or surge machine (not marking) makes water circulation stir, pass through photosynthesis, algal bloom, normal growth, and make water body produce a large amount of dissolved oxygen, and natural bait, the current of outer circulation aquaculture model China and foreign countries are entrained with the materials such as algae and can again enter water treatment district 2 through greenhouse water inlet 16 again.
Owing to being provided with micro-pore oxygen increasing device 8 in water treatment district 2, by micro-pore oxygenation unit 83 aeration micro-bubble out to water oxygenation, Ji Pao district 14 is pumped into from the delivery port of pump box casing 81 upper end, and utilize the tension force on microbubble surface, by the suspension in water body and soluble protein species adsorbs on microbubble, and the SO of great quantities of spare in water
2and CO
2also to overflow from the delivery port pump box casing 81 in the lump. the harmful substances such as suspension foam micro-pore aeration separated by Ji Pao district 14 collect out, are discharged outside culturing pool by pipeline.
After Shui Jingjipao district 14 after last water treatment district 2 processes processes, enter combination biofiltration district 3 again, carry out biofiltration, remove ammonia nitrogen, owing to being provided with some biofiltration casees 9 in combination biofiltration district 3 water, multiple fiber biological filter tow 95 is provided with in it, described fiber biological filter tow 95 is provided with fiber 99, when adding NH_3-N treating bacterium in water, then can post contracting on fiber 99, the ammonia nitrogen flowing through water body is processed, water after the process of biofiltration case, flowing into cultivation by separation net board wall 10 raises in district 4, carry out fresh water to supplement, make it recycle.
The present invention adopts above-mentioned technique and equipment to cultivate, and through demonstration experimental verification, its data are as follows:
1, the combination biofiltration case of every cubic metre, can process the ammonia nitrogen of 500 kilograms of fish normal growth excretions every day, is more than 2-10 times of other NH_3-N treating biology bag.
2, per mu yield can reach 120 tons fresh fish year of the present invention, be the 60-120 of tradition cultivation doubly.
3, the bait that in the present invention, natural pond liquid is cultivated can reduce the feedstuff of part, reduces production cost, and shortens growth cycle
4, a series of device processes water body of the present invention, can make water quality clarity reach more than 1 meter, no suspended substance in water.
5, the facility long service life in the present invention, for ease of maintenaince, simple to operate, continuity is strong, safety and stability High-efficient Production.
6, in the present invention, the oxygen transfer efficiency of oxygen is greater than 5kg/kw.h, fish loading amount > 7500kg/kw.h during its fish normal growth, and the pump water yield is large.
It is consistent with prior art that the present invention does not describe part, and therefore not to repeat here.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing specification of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
