Description
Technical field
The utility model is related to a kind of marine sewage treatment system.
Background technology
Promulgate that MEPC 227 (64) resolves in 64 meetings of MEPC on October 3rd, 2012, added sanitary sewage disposal
The discharge standard of total nitrogen and total phosphorus in system, implemented from 1 day January in 2016.
With the development of scientific and technological level, various sewage disposal technologies and equipment are also evolving, and processing method is a variety of more
Sample, main active sludge, biomembrance process, membrane bioreactor, physico-chemical process etc., obtained on various ships extensively
Application.
Activated sludge process：Traditional activated sludge process is technique the most ripe in biological water process, because ship lives dirty
Topmost pollutant is organic matter in water, therefore activated sludge process becomes one preferred technique and used, and whole system includes
Aeration tank, sedimentation basin, sterilizing chamber, air-blast device and sludge refluxing apparatus.But current traditional activated sludge process is applied in ship life
Still there is certain defect in sewage disposal living：Traditional activated sludge process needs continuously to be aerated into aeration tank, required to expose
Gas pond body product is larger, aboard ship takes much room, and using space is extremely limited and valuable on ship；Ship life is dirty
Water raw water yield exist fluctuation, it is few with evening hours sewage yield berthing, and at noon with certain evening hours sewage yield
It can increase, due to traditional activated sludge process because plant bulk is fixed, in addition to reducing running series, have no idea to adapt to come
The height change of Water l oad；The requirement to nutritive salt nitrogen and phosphorus indexes is added in new regulations at present, but is taken off in activated sludge process
Nitrogen and dephosphorization are interactional, and the difficulty of synchronous denitrification dephosphorizing is larger, and current activated sludge process is the denitrogenation dephosphorizing reached
Effect usual practice is aerobic and anaerobism alternating change the reaction member of increase, and this is difficult for Sewage from Ships processing
To realize.
Biomembrance process：Biomembrance process and activated sludge process main difference is that activated sludge process relies on suspension flow in aeration tank
The dynamic activated sludge that lands carrys out decomposing organic matter, and biomembrane then relies primarily on and is bonded to the microbial film of carrier surface to purify
Organic matter.What is aboard ship mainly utilized at present is microbe films osculation oxygenation method, and this method has activated sludge process and biomembrance process concurrently
Advantage.Compared with activated sludge process, biomembrance process particularly biological contact oxidation process has that biomass is big, disposal ability strong,
Take up an area the advantage saved, impact load has stronger adaptability, and the yield of excess sludge is few.But it has the drawback that reactor
Interior to replace changing environment without obvious aerobic and anaerobism, Nitrogen/Phosphorus Removal is not generally high；Due to the presence of filler, reactor
There is non-uniform phenomenon in interior gas distribution and water distribution, filler, which has the risk blocked, to be needed to install back purge system.
Membrane bioreactor：Abbreviation MBR, is behind biological water treating method plus one group of membrane module, typically using milipore filter,
Biological treatment is organically combined with UF membrane, the problem of water outlet concentration of suspension is high can be preferably overcome.Need to refer to
Go out, membrane module use cost is higher for a long time, the problems such as fouling membrane, membrane module are cleaned progress is slow, becomes
Restrict bottleneck of the MBR devices in the marketization of Sewage from Ships process field.
Physico-chemical process：Different from bioanalysis, physico-chemical process is to eliminate consolidating in water by processes such as flocculation, precipitation, absorption, filterings
Body material, is allowed to be separated with dissolved organic matter, remaining sewage is sterilized, finally discharges outboard.This device is than biological
A method processing few Bacteria Culture phase, therefore can start at any time.Further, since sewage residence time in device is short, it is only
The time of chemical agent reflection, so small volume, using flexible, impact load is adaptable.Most importantly physico-chemical process
Substantially the high problem of water outlet concentration of suspension can be overcome.The deficiency of physico-chemical process is, it usually needs adds flocculant or uses
Sorbing material, because the object of Sewage from Ships processing is full sewage, including " Heisui River " and " buck ", therefore pollutant burden
Higher, required medicament usage amount is big, and operating cost is high；And physico-chemical process does not have the organic matter in corresponding biochemical reaction, sewage
With nitrogen it is difficult to thoroughly remove.
But there is presently no a kind of gratifying Sewage from Ships processing method, therefore, in order to meet international sea
Thing tissue new standard requirement, the one or more novel ship sanitary sewage disposal technologies of research and development just seem especially important, can
To say being extremely urgent.
Utility model content

Be thoroughly mixed characteristic, with stronger anti impulsion load ability；CASS sets biological selector, promotes the life of flocculation-type bacterium
Long and breeding, so as to inhibit the generation of sludge bulking, efficiently carries out nitration denitrification, Nitrogen/Phosphorus Removal is notable, with reference to
Photochemical catalytic oxidation sterilizes, efficient, environmental protection, final discharge water is met related pact index request.
The technical scheme realized above-mentioned purpose and taken, including regulating reservoir, the regulating reservoir connect CAST through B1 macerator pumps
Provided with selection area and main reaction region in reaction tank, CAST reaction tanks, selection area is connected with the sections bottom of main reaction region two, and in choosing
Select and agitator be provided with area and main reaction region, the main reaction region bottom is provided with micro-hole aerator, micro-hole aerator connects air pump,
CAST reaction tanks bottom is through B2 sludge pumps connection selection area and sludge-tank, and sludge-tank upper end connects regulating reservoir through overflow pipe, described
Provided with water installations are strained in main reaction region, water installations output end connection clear water reserviors are strained, clear water reserviors bottom is urged through B3 blowdown pumps connection light
Change sterilizer.
Beneficial effect
The utility model has advantages below compared with prior art.
1st, it is adapted to Sewage from Ships and discharges unstable, the characteristics of hourly variation factor is big；
2nd, pass through muddy water mixed solution by water inlet-aeration, precipitation, slash water, water inlet-idle completion a cycle during operation
