Abstract
The invention discloses a quick start method of a biofilter in a low temperature environment. The method comprises the following steps: mounting an independent biological filler preparation pond outside a circulating water aquaculture system, wherein the biological filler preparation pond is provided with an oxygenation aerator; before starting the circulating water aquaculture system, introducing aquaculture water into the biological filler preparation pond from a circulating water workshop; adding fluidized ring suspended filler in the aquaculture water of the biological filler preparation pond, heating the aquaculture water, controlling water temperature at 28-30 DEG C, and controlling aeration by utilizing the oxygenation aerator so that a biological film can be formed quickly in the biological filler preparation pond; and after formation of the biological film, transferring into a biological filter of the circulating water workshop so that the microorganisms gradually get adapted to the water environment through water exchange. According to the invention, the biological film can be quickly started in a circulating water aquaculture facility with the water temperature being 16-20 DEG C or below or in a low temperature condition.
Description
Technical field
The present invention relates to technical field of aquaculture, be specifically related to a kind of quick start method based on biological filter under low temperature environment.
Background technology
Under closed recirculating cultivating condition, soluble pollutants NH in aquaculture water
4 +, NO
2 -, NO
3 -deng removal mainly complete in biological filter.Have the bio-carrier of unlike material in biological filter, the microorganism adsorption such as nitrobacteria, nitrite bacteria, on bio-carrier, forms microbial film.These autotrophic microorganisms for nutritive substance, reduce the content of soluble pollutants in water body with organism such as the ammonia nitrogen in water body, nitrite while own growth, thus ensure water conditioning, do not impact the health of cultured product.
First new closed recirculating cultivating system will start biofilm treatment system before running, and nitrobacteria and Nitrite bacteria more than 20 DEG C time activity the highest, will be affected lower than the conversion of ammonia under 20 DEG C of conditions.Lower or when carrying out the cultivation of the cold water fish such as salmon trout, lower water temperature can slow down microbial growth reproduction speed in water temperature, and then cause microbial film to start excessive cycle, affect the operation of whole circulating water culture system.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, when providing one to be applicable to water temperature less than 16 ~ 20 DEG C, need new start circulating water cultivation facility or cold condition under need to carry out the quick start method based on biological filter under low temperature environment that microbial film starts fast.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Based on a quick start method for biological filter under low temperature environment, described method comprises the following steps:
Step one, outside at circulating water culture system, arrange independently biologic packing material and prepare pond, described biologic packing material prepares pond configuration oxygenation aeration facility;
Step 2, before circulating water culture system starts, from the aquaculture water in recirculated water workshop, introduce aquaculture water be added into described biologic packing material and prepare in pond; Aquaculture water in pond is prepared to biologic packing material and uses fluidisation ring floating stuffing, and water body is heated, control water temp at 28 ~ 30 DEG C, use described oxygenation aeration facility to control aeration simultaneously, make described biologic packing material prepare to form microbial film fast in pond;
After step 3, described biofilm formation, transfer them in the biological filter in recirculated water workshop, exchange through water body, make microorganism adapt to water body environment gradually.
Further technical scheme also comprises step in the biologic packing material preparation pond aquaculture water in recirculated water workshop being supplemented to outside after being step 3.
Further technical scheme is that step 2 also comprises and prepares to add probiotics and micro-step in pond to described biologic packing material, makes microorganism prepare in pond growth and breeding form microbial film fast at biologic packing material.
Further technical scheme is heated water body by heating unit in step 2.
Further technical scheme by pipeline, the aquaculture water in recirculated water workshop is supplemented to outside biologic packing material to prepare in pond.
Further technical scheme is that microorganism comprises nitrobacteria, nitrite bacteria.
Further technical scheme to be low temperature environment be aquaculture water temperature is lower than the environment of 16 ~ 20 DEG C.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can carry out microbial film and start fast under the circulating water cultivation facility of water temperature less than 16 ~ 20 DEG C or cold condition, when without the need to additional cost, ensure biofilm system nutrition supply endlessly, thus ensure microorganisms stable growth, can be the microbial film that biological treatment system provides ripe at any time.

Embodiment
The present embodiment discloses a kind of quick start method based on biological filter under low temperature environment, when the method is applicable to water temperature less than 16 ~ 20 DEG C, need new start circulating water cultivation facility or cold condition under need to carry out the situation that microbial film starts fast.
Concrete the present embodiment method comprises the following steps:
Step one, outside at circulating water culture system, independently biologic packing material is set and prepares pond, and pond configuration oxygenation aeration facility is prepared to biologic packing material;
Step 2, before circulating water culture system starts, from the aquaculture water in recirculated water workshop, introduce aquaculture water be added into biologic packing material and prepare in pond, aquaculture water in pond is prepared to biologic packing material and uses the fluidisation ring floating stuffing that surface-area is larger, and take the measures such as heating rod to heat water body, control water temp within the scope of 28 ~ 30 DEG C, reach the optimum temperature range of nitrobacteria growth metabolism, use described oxygenation aeration facility to control aeration simultaneously, and suitably add probiotics and trace element, biologic packing material is prepared in pond with the ammonia nitrogen in water body, the organism such as nitrite are the autotrophic microorganism of nutritive substance, described autotrophic microorganism can be nitrobacteria, the microorganisms such as nitrite bacteria, its quick growth and breeding thus form microbial film fast,
After step 3, biofilm formation, transfer them in the biological filter in recirculated water workshop, exchange through water body after a while, make microorganism adapt to water body environment gradually.
Step 4, recirculated water workshop aquaculture water is supplemented to outside biologic packing material by pipeline and prepares pond, thus security reserve pond biofilm system nutrition supply endlessly, ensure that it grows continually and steadily, can be the microbial film that biological treatment system provides ripe at any time.
