Description
Technical field
It is specifically a kind of to handle for ship or sewage the present invention relates to technical field of sewage
Nitrogen rejection facility.
Background technology
It is outstanding day by day the problems such as earth water environment pollution, Water Eutrophication, water saving with the development of World Economics, more
Strict sewage drainage standard is formulated come more countries and regions, to protect the water environments such as river, lake, ocean.
In recent years, with the development of shipping business, the problem of environmental pollution of this mobile source of ship, particularly to sensitizing range（Such as water source
Ground, nature reserve area etc.）Quality of water environment influence, be just progressively valued by people.International Maritime Organization in 2012
(IMO) in the MARPOL73/78 supplemental provisions IV promulgated --- on the basis of preventing that Sewage Pollution is regular, it is further proposed that
《Vessel Waste discharge standards in 2012 and the teachings of wastewater treatment equipment performance test》, to Sewage from Ships processing
Discharge standard has made tightened up regulation, adds the pollutant concentration conversion after the indexs such as total nitrogen, total phosphorus and dilution processing
Method.Some existing Technology of Ship Domestic Sewage Treatment can not meet newest IMO Sewage from Ships processing standard, because
This, it is necessary to existing treatment technology and device are improved or researched and developed new treatment technology.At present, external relatively common ship
Oceangoing ship sanitary sewage disposal technology mainly has biochemical process and electrochemical process, biochemical process such as activated sludge process and biomembrance process, electrochemistry
Method such as bypasses electrolysis, and domestic treatment technology is mainly activated sludge process and MBR methods and introduces external processing equipment and changed
Good associated processing device.
The problem of prior art is present be：The biochemical process processing residence time is long, and processing unit volume is big, it is necessary to turn out
The a number of activated sludge of such water quality is adapted to, operating personnel should possess professional knowledge, open and close difficulty, once occur longer
The stoppage in transit of time, needs to cultivate activated sludge again during restarting, to significantly water quality and quantity change impact resistance compared with
Odorant can be produced in difference, and biochemical process, periodic cleaning processing unit is needed and adds chemosterilant, medicament storage is not
Just.Although the electrochemical process processing residence time is short, mixability is not abundant enough, reduces the efficiency for removing pollutant, it is impossible to
Meet the requirement of the newest Sewage from Ships discharge standards of IMO and stable and reliable operation.
The content of the invention
A kind of denitrogenation dress for Sewage from Ships processing that the purpose of the present invention is in view of the shortcomings of the prior art and provided
Put, using the electrolysis cells of tubular pole structure, improve flow velocity of the sewage in electrode, the sodium hypochlorite for producing seawater electrolysis
It is sufficiently mixed with sanitary sewage, further improves oxidability, the ammonia nitrogen direct oxidation in sewage is nitrogen by intensive treatment effect
Gas phase is transferred to, electrochemistry denitrogenation is realized, the requirement to nitrogen removal rate in the newest Sewage from Ships discharge standards of IMO is met,
Compact conformation, equipment volume is small, and electrolytic efficiency is high, and denitrification effect is good, and keying is simple to operate, and water quality and quantity is adaptable, fortune
Row is safe efficient, is especially suitable for the sanitary sewage disposal of all kinds of type ships.
Realizing the technical scheme of the object of the invention is：A kind of nitrogen rejection facility of Sewage from Ships processing, is characterized in this
Nitrogen rejection facility is sequentially connected in series with macerator pump, pipe-line mixer, electrolysis cells and letdown tank by receiving slit and constituted, the pipeline mixing
Device import connection and macerator pump are the sea water pump being arranged in parallel；The letdown tank is provided with dosing pump and dosing tank.
Electrolysis cells are the tubular type unit electrolytic bath that negative electrode outer tube is set with anode inner tube.
The present invention has compact conformation compared with prior art, and equipment volume is small, and electrolytic efficiency is high, and denitrification effect is good, opens
Closed operation is simple, and water quality, water are adaptable, and operation is safe efficient, and processing cost is low, is especially suitable for all kinds of type ships
Sanitary sewage disposal.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Refering to accompanying drawing 1, the present invention by receiving slit 1, macerator pump 2, pipe-line mixer 3, electrolysis cells 4 and letdown tank 5 successively
Concatenation is formed, and entrance point connection and the macerator pump 2 of the pipe-line mixer 3 are the sea water pump 8 being arranged in parallel；The letdown tank 5
It is provided with dosing pump 6 and dosing tank 7；The electrolysis cells 4 are using the unit electrolytic bath of tubular structure, and its negative electrode is outer tube, sun
Extremely inner tube.
The present invention so works：Sanitary sewage on ship is stored by pipeline access receiving slit 1, in receiving slit 1
The seawater that the size-reduced pump 2 of sanitary sewage is introduced after crushing the larger solid particle in sewage and fibrous material with sea water pump 8
Input channel blender 3, injection electrolysis cells 4 after sanitary sewage is sufficiently mixed with the seawater introduced, pass through electrolysis and produce together
High-concentrated sodium hypochlorite enter letdown tank 5 together with sanitary sewage, sodium hypochlorite aoxidized in sanitary sewage in letdown tank 5
The reducing substanceses such as ammonia nitrogen, are that nitrogen is transferred to gas phase by the ammonia nitrogen direct oxidation in sewage, realize that the electrochemistry of sanitary sewage takes off
Nitrogen processing, reaches the requirement to nitrogen removal rate in the newest Sewage from Ships discharge standards of IMO, then will be added by dosing pump 6
Chemicals in medicine-chest 7 adds letdown tank 5 and the chlorine residue in sewage is reduced, and makes chlorine residue in the sewage of discharge up to standard.This
Invention uses " being thoroughly mixed electrolysis-type " treating ship domestic sewage through electrolytic process, sodium hypochlorite is sufficiently mixed with sewage, enters one
Step improves oxidability, and intensive treatment effect carries out the degraded of pollutant without cultivating activated sludge, and tubular pole improves sewage
Flow velocity in electrode, reduces the volume of electrolysis cells, realizes automatic pollutant removal and sterilization.
Simply the present invention is further illustrated above, and is not used to limit this patent, and all is equivalence enforcement of the present invention,
It is intended to be limited solely by within the right of this patent.
