Description
Technical field
The invention belongs to the category of agriculture field marine fish culture, sea-farming industrialization meets National agricultural industry hair
Exhibition direction, is related to industrial circulating water fish cultural technique, especially in a kind of aspect recirculating aquaculture system for sea-farming
The method for designing of light-transmission type biofilter.
Background technology
The cycle water fish-cultivating factory biofilter of China is all the method for designing of the lighttight complete darkness in roof, according to reality
Trample, it is believed that dark condition has many unfavorable, and Phytoplankton ＆ Suspension can not survive under dark condition, particularly imitated with preferable purification of water quality
The various green algaes of fruit cannot survive, and the waters without algae cannot set up water ecology balance, ecological unbalanced
This reason is the absence of the diversity of aquatic animals and plants, it is impossible to which the water quality for setting up the ecological balance is not suitable for cultured fishes.Therefore this is
A big defect in current closed cycle water fish-cultivating technological design, should give innovation and improves, in closed circulation water cultivation
It is a large amount of in system to cultivate the Phytoplankton ＆ Suspension with water quality purification function, a reliable and stable ecological balanced system of breeding fish is created,
It is significant for developing industry aquaculture.
In disclosed technology, the Application No. 2013101186590.1 of such as Chinese invention patent is " ecological closed
Cycle water fish-cultivating method ", major technique stores precipitation including extracting seawater, sets up water distribution workshop, fish farming shop, separation of solid and liquid,
Biofilter purifies water, disinfection by ultraviolet light, oxygenation, and fish farming shop sewage flows into retaining sedimentation basin after wetland purification is up to standard
Reuse.In actual application, find following not enough：
1st, there is no various biological survivals such as hydrobiontic alga in the biofilter of roof shading complete darkness.Hydrobiontic alga includes
Various Phytoplankton ＆ Suspensions such as sea lettuce, Enteromorpha have can decompose and absorb it is nitrogenous in water body, containing Phosphorous species, such as ammonia nitrogen, Asia
Nitrate nitrogen, nitrate nitrogen and phosphate are exceeded, and harmful to fish growth, these materials are exceeded, inspire fish disease；Set growth as
The biologies such as barnacle, sea anemone and oyster, the function with control microorganisms in water content, above-mentioned biological shortage, under subenvironment
The ecological balance is broken, water quality purification function missing, causes fish disease to occur.In this regard, should give innovation and improve.2nd, in order to increase
Plus light transmittance, promoting various biological growths such as algae, the depth of biofilter is relative to be lowered, and projected depth is 1500mm, than
Reduction 1000mm originally, illumination can be irradiated to biofilter bottom, be adapted to algae, the barnacle of set growth, sea anemone and oyster
Etc. the growth of various marine organisms, a good ecologic balance environment is built.
The content of the invention
In view of the above problems, the invention provides a kind of light-transmission type bio-decontamination cycle water fish farming system, biological filter is ensured
The daylighting effect in pond, and the depth of biofilter is changed, such biofilter light can be irradiated to bottom, be conducive to seawater
Algae and the growth of other biological, hydrobiontic alga belong to plant, with ammonia nitrogen in absorption cleaning water, nitrite, nitrate nitrogen and
The biological microorganism that can largely filter in drinking water body such as phosphatic function, barnacle, sea anemone and oyster that set grows, controls cause of disease
The quantity of microorganism, is that the purification of water quality of factory circulating water fish culture system provides safeguard, and reduces the generation of fish disease, realizes health
Cultivation and food security.
