Description
Technical field
It is specifically a kind of quickly to remove following for residual antibiotic the present invention relates to a kind of culture environment of aquatic products protection technique
Ring water cultivating system.
Background technique
Global culture fishery is quickly grown, and China accounts for 60% or more of global aquaculture production.Aquaculture water
Domain includes fresh water, seawater, salt water three classes, and aquaculture type includes pond culture, enclosure culture in lake, mudflat aquaculture, shallow sea
With Deep sea net cage cultivation etc., aquaculture model includes extensive style, half intensive culture formula and industrial aquaculture etc..Industrial aquaculture also known as follows
Ring water cultivating system (Recirculating Aquaculture System, abbreviation RAS), is culture fishery main development side
To integrated use advanced technology and industrialization means control the living environment of aquaculture organism, scientific management are carried out, to put
The de- Natural resources conditions such as soil and water limitation, is a kind of high-density breeding mode.
As cultivation scale and cultivation density are continuously increased, water quality deterioration, disease and the environment generated in breeding process is dirty
The problems such as dye, becomes increasingly conspicuous.The various bacteriosis of aquiculture animal are controlled using antibiosis class drug, remain logical both at home and abroad
Capable countermeasure.Currently, China allow using aquatic products veterinary drug in antibiotics have 22 kinds, be concentrated mainly on 5
Major class: aminoglycoside (neomycinsulphate), Tetracyclines (Doxycycline Hyclate), amphenicols (Thiamphenicol, Florfenicol
Deng), sulfa drugs (sulphadiazine, sulfamethoxazole, sulfadimidine, Sulfamonomethoxime Sodium etc.), quinolones
Drug (Enrofloxacin, lactic norfloxacini, niacin norfloxacin, oxolinic acid, flumequine etc.).
However, the unreasonable use of antibiotic, results in many environmental problems such as antibiotic residue, resistant gene pollution.
Cultivated animals type is more, and physiological property is different, and there are greatest differences for the effect of drug and the metabolic rule to drug；Traditional aquatic products
Cultivation takes group by medicine mostly based on Polyculture, causes precisely to be administered difficult；And breeding water body multiplicity, medication effect
It is influenced by water body environment and physicochemical property.These reasons lead to aquaculture overdose, inevitably generate antibiosis
Plain medicament residue problem destroys the microecological balance of aquiculture animal, pathogenic bacteria drug resistance and the resistant gene pollution of initiation
Problem.
Currently, the minimizing technology of antibiotic is more, including bioanalysis, physical method and oxidizing process.Current degradable antibiotic
Functional microorganism mainly have bacterium and fungi two major classes.Since concentration is lower in water environment for antibiotic, so needing to use
Many advantages, such as immobilized microorganism is handled, and wherein investment is small, granule strength is high to microbiological effect due to it is mesh
The process for fixation of preceding most study.Physical method mainly includes absorption method, Coagulation Method and membrane separation process etc., wherein absorption method
Since easy to operate, low in cost, the time-consuming advantages such as short are widely used, most common adsorbent is active carbon.Oxidizing process
It include mainly chemical oxidation, photooxidation, electrochemical oxidation, ultrasonic oxidation.Wherein, the degradation speed of photochemical oxidation method is fast,
Remineralization efficacy is good, and reaction condition is mild, does not specially require to temperature, pressure etc., treatment process is simpler, is highly suitable for difficulty
In the processing of biodegradable organic pollutant, not only the inhibition of microorganism can be made to obtain by the antibiotic after ultraviolet photolysis
Alleviate, while can effectively mention its biodegradation rate.
Circulating water culture system is the system of a closure, and system can precisely be used according to the needs science of cultivated animals
Antibiotic, but remaining antibiotic in system need quickly to be removed, otherwise will affect the water treatment unit of the circulatory system
Function bacterial activity leads to whole system water quality deterioration so that biofilter water treatment capacity declines.Also lacking at present can be fast
The effective technology method of speed removal circulating water culture system residual antibiotic.
