Description
Technical field
The utility model relates to technical field of sewage, specifically a kind of integration for Sewage from Ships processing
Device.
Background technique
With the further development of shipping industry, Sewage from Ships is discharged as a kind of mobility pollution sources to sea
The influence in ocean, Water Environment in Urban Rivers and lake, reservoir is also on the rise.At the same time, the consciousness of people's environmental protection constantly mentions
Height, State Bureau of Environmental Protection also correspondingly revise ship pollution discharge standard, increase PH, COD, total chlorine, TN,
The item controlleds such as NH3-N, TP；And received BOD, SS tight, the emission limit of heat-resisting coliform group count, the processing of Sewage from Ships
Also by stern challenge.
Currently, Sewage from Ships processing mode is broadly divided into two kinds: first is that without emission type sewage treatment, second is that emission type
Sewage treatment.Sewage is mainly unified collection storage using the water storage tank on ship by no emission type sewage treatment, waits until ship
It pulls in shore again to handle sewage discharge, this mode is not suitable for large ship；Emission type sewage treatment is then by handling hand accordingly
Discharge will be carried out in accordance with regulations in section after sewage treatment to discharge standard.Emission type sewage water treatment method is broadly divided on usual ship:
Physico-chemical process, biochemical method, electrochemical process, advanced oxidation processes etc..Up to the present, traditional Technology of Ship Domestic Sewage Treatment has been
It is extremely difficult to the emission request of new standard.
Utility model content
Since the ship health department excretion period is shorter, the sewage of discharge is more fresher than sewerage system, decomposes
Degree is lower, therefore pollutional load is higher；And since personnel concentrate, so that the variation of draining water quality and quantity is very greatly, this is just to it
Sewage treatment process proposes higher requirement.For deficiency existing for existing traditional ship sanitary sewage disposal technology, fit
Realistic development is answered, the utility model provides a kind of integrated apparatus and method for Sewage from Ships processing, it is intended that solves
Sewage from Ships discharges problem not up to standard.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
A kind of integrated apparatus for Sewage from Ships processing, including electrochemical case, denitrification case, membrane biological reaction
Case, equipment room, electric cabinet and spray tank；Cathode plate and anode plate form electrolysis system built in the electrification case；The denitrification

Enter the aerobic section in the membrane biological reaction case through the denitrification case treated sewage, in this stage ammonia nitrogen
It under the action of nitrococcus, nitrifier, and then decomposes and is oxidized to cultured water and nitrate nitrogen, reaction is as follows:
Nitrococcus: NH4 ++3/2O2→NO2 -+H2O+2H+
Then cultured water is further converted to nitrate nitrogen under the action of Nitromonas, and reaction is as follows:
NO2 -+1/2O2→NO3 -
Nitrifier: NH4 ++2O2→NO3 -+H2O+2H+
Sewage backflow after nitration reaction to the denitrification case, nitrate nitrogen and cultured water anoxic environment item
Part, and under the action of denitrifying bacterium, it is reduced into N2.It reacts as follows:
NO2 -+ 3H (electron donor) → 1/2N2+H2O+OH-
NO3 -+ 5H (electron donor) → 1/2N2+2H2O+OH-
Its dephosphorization principle is as follows:
Under the denitrification case anoxia condition, the intracorporal ATP of polyP bacteria is hydrolyzed, and releases PO4 3-And energy, shape
At ADP；Under aerobic condition, polyP bacteria carries out aerobic respiration, constantly decomposes its intracorporal organic matter, while also from external environment
Organic matter is absorbed, and the phosphate radical of this part intake is far longer than the phosphate radical of anoxic section release, goes dephosphorization with this.
(3) pass through the disinfection of ultraviolet light, then discharge.
Compared with prior art, the advantages of the utility model and good effect is as follows:
