Mass formed by blood stasis.
Therefore, for breeding seawater, ammonia nitrogen concentration is one of main Con trolling index.But present inventor exists
It is found in long-term R＆D process, the water treatment technology of sea-farming water removal ammonia nitrogen takes longer in the prior art, and handles
Ammonia nitrogen concentration is still unsatisfactory for requiring afterwards.
Invention content
The application can fast and effeciently be gone mainly solving the technical problems that provide a kind of sea-farming water treatment system
Except the ammonia nitrogen in sea-farming water, the COD in sea-farming water can be also efficiently removed.
In order to solve the above technical problems, the technical solution that the application uses is：A kind of sea-farming water process is provided
System, the sea-farming water treatment system include：Biological contact oxidation sub-systems, oxidant launch subsystem and ceramic membrane
Micro-filtration subsystem；The biological contact oxidation sub-systems are used for through Biological Contact Oxidation Process to pending sea-farming water
Raw water carries out biological contact oxidization treatment to remove the ammonia nitrogen in the sea-farming water raw water, obtains first order processing water；Institute
It states oxidant dispensing subsystem to connect with the biological contact oxidation sub-systems, for launching oxidant, to pass through the oxidation
Agent carries out oxidation processes to first order processing water and further removes the ammonia nitrogen in the sea-farming water raw water；Ceramic membrane
Micro-filtration subsystem is filtered processing for handling water to the first order after oxidation processes by ceramic membrane, obtains at the second level
Manage water.
The advantageous effect of the application is：The case where being different from the prior art, the application sea-farming water treatment system include：
Biological contact oxidation sub-systems, oxidant launch subsystem and microfiltration of ceramic membrane subsystem；The bio-contact oxidation subsystem
System to pending sea-farming water raw water by Biological Contact Oxidation Process for carrying out biological contact oxidization treatment to remove
Ammonia nitrogen in the sea-farming water raw water obtains first order processing water；The oxidant is launched subsystem and is connect with the biology
Oxidation subsystem connection is touched, for launching oxidant, is carried out at oxidation with handling water to the first order by the oxidant
It manages and further removes the ammonia nitrogen in the sea-farming water raw water；Microfiltration of ceramic membrane subsystem, for passing through ceramic membrane to oxygen
Change treated first order processing water and be filtered processing, obtains the second level and handle water.Biological Contact Oxidation Process can effectively be gone
Except the ammonia nitrogen and COD in sea-farming water, and processing cost is relatively low, and sludge output is small, and can be to effectively reduce subsequent oxidation agent
Dosage provide technical foundation, treatment effect stablize, investment it is less；Using oxidant after Biological Contact Oxidation Process is handled
Processing, can further remove the ammonia nitrogen and COD in sea-farming water, to meet discharge standard, ceramic membrane is easily assembled to, and is accounted for
Ground area is small, and flux is big, and has stronger tolerance to soda acid and oxidant, can carry out mud-water separation, makes to hang in water
Floating content of material reduces, and improves effluent quality；Therefore, by the above-mentioned means, can fast and effeciently remove in sea-farming water
Ammonia nitrogen, can also efficiently remove the COD in sea-farming water, and economic and practical.

Material, bottom of pond aeration is oxygenated sewage, and sewage in pond body is made to be in flow regime, to ensure sewage and the filler in sewage
It comes into full contact with, avoids in biological contact oxidation pond there are sewage from contacting uneven defect with filler.It purifies the substantially former of waste water
Reason is identical as general biofilm, adsorbs the organic matter in waste water with biomembrane, under conditions of aerobic, organic matter is by microorganism
Oxygenolysis, waste water are purified.
Fa Zhong Institute of Micro-biology is aerobic is supplied by blast aeration for this, after biofilm development to certain thickness, micro- life of filler wall
Object can carry out anaerobic metabolism because of anoxic, and the souring that the gas and aeration of generation are formed can cause falling off for biomembrane, and
Promote the growth of neoformation film, at this point, the biomembrane to fall off will be flowed out with water outlet outside pond.Biomembrane in biological contact oxidation pond
It is made of zoogloea, der Pilz, fungi, protozoan and metazoa.In activated sludge process, der Pilz often influences just
The factor of normal biological purification；And in biological contact oxidation pond, der Pilz spatially structure between filler gap increases greatly
The contact surface of biofacies and waste water is added, simultaneously as der Pilz has stronger oxidability to most organic matters, to water
Matter load variations have larger adaptability, so being the potent factors for improving detergent power.
Compared to traditional activated sludge process and biological filter process, Biological Contact Oxidation Process has large specific surface area, dirt
Mud concentration is high, sludge age is long, coefficient of oxygen utilization is high, save power consumption, sludge yield is few, operating cost is low, equipment is easy to operate, easy
The technological advantages such as repair；It is short the time required to processing moreover, its purification efficiency is high, to the variation adaptability of organic loading of intaking compared with
By force, it is not necessary to carry out sludge reflux, while there is no sludge bulking problem, operational management is convenient.
Ceramic membrane (Ceramic Membrane) is also known as inorganic ceramic membrane, is prepared through special process with inorganic ceramic material
And the anisotropic membrane formed.Ceramic membrane is divided into two kinds of tubular ceramic membrane and ceramic membrane.Tubular ceramic membrane tube wall gathers micropore,
Under pressure, material liquid flows in membrane tube or on the outside of film, and small-molecule substance (or liquid) penetrates film, macromolecular substances
(or solid) is rejected by, to reach the purpose of separation, concentration, purifying and environmental protection.Ceramic membrane plate face is gathered micropore, root
According within the scope of certain membrane aperture, then permeability is different for the material molecule diameter difference of infiltration, and the pressure difference with film both sides is
Driving force, film are filter medium, certain pressure effect under, when feed liquid flows through film surface, only allow water, inorganic salts, small point
Sub- material permeance film, and the macromolecular substances such as suspended matter, glue and microorganism in water is prevented to pass through.
Compared to traditional polymer separation membrane material, ceramic membrane has chemical stability good, can be acidproof, alkaline-resisting, resistance to organic
Solvent；Mechanical strength is big, can back flush；Anti-microbe ability is strong；High temperature resistant；The advantages that pore-size distribution is narrow, separative efficiency is high,
Separation, clarification, purifying, concentration, degerming, the desalination etc. that can be used in technical process.
