Description
Technical field
The present invention relates to technical field of waste water processing, and in particular to a kind of ship wet process of FGD washs water treatment system
And method.
Background technology
Ship flue gas desulfurization washings be marine diesel discharge smoke-gas wet desulfurization during produce need externally discharged waste water.
Current marine diesel wet process of FGD mode is mainly magnesium processes and sodium method, no matter which kind of desulfurizing agent is used in sweetening process,
Desulfurization washes certainly will be produced.Current International Maritime Organization（IMO）Washings discharge to ship desulfurization exhaust gas cleaning system
Propose to be strict with, define the limit value in outer draining such as pH value, SS, turbidity, temperature, polycyclic aromatic hydrocarbon, therefore flue gas desulfurization
Washing water treatment system accounts for critical positions in whole marine diesel flue gas desulphurization system.Lead in ship desulfurization fume washings
Often contain higher suspension, colourity, COD（Mainly caused by inferior sulfate radical）, dissolved with part polycyclic aromatic hydrocarbon in water, at the same chlorine from
Son and heavy metal concentration are higher.PH value general control is between 4~6 in washes.In addition, can also have sometimes in washings
A small amount of oil slick and finely divided oil.
Magnesium processes and sodium method marine diesel flue gas desulfurization, are all the new technology that lower appearance is expedited the emergence of in IMO supplemental provisions VI, current sodium
Method desulfurization technology has begun to use abroad, and because MgO is cheap at home, some power plant use magnesium processes desulfurization
SO in technology purifying smoke2, magnesium-based seawater method marine diesel engine flue gas desulfurization technique also obtained classification society's certification, will
Come into operation.Limitation and other specific factors due to ship space, it is small that washing water treatment facilities need to meet floor space, collection
High into degree is changed, anti-water quality and quantity fluctuates the characteristics of ability is high compared with strong and automaticity, and artificial operation is avoided as far as possible or is thrown
Adding medicine.Current sodium method and magnesium processes desulfurization fume washing water treatment system use for reference the desulfuration waste water treatment process of power plant mostly, account for
Ground space is big, integrated and automaticity is relatively low, it is impossible to adapt to the special running environment of ship.
For example, in some marine exhaust desulfurization washing water treatment technologies and its processing system based on sodium alkali, using adding
Alkali lye adjusts the technique of pH value → oxygenic aeration → flocculation-air floating → charcoal absorption, does not consider that the disposal of flotation tank scum silica frost is asked
Topic；Flotation tank floor space is big, it is impossible to adapt to the special operation condition condition of vessel roll；Charcoal absorption polycyclic aromatic hydrocarbon and petroleum-type
Easily it is backwashed and takes out of, backwash water whereabouts is not explained；Flotation tank goes out that aqueous suspension degree of stability is poor, and active carbon filter load is big.
In some ship desulfurizing waste water processing devices and method, using aerating oxidation → jet dosing flocculation → eddy flow solid-liquid
The handling process of separation → adsorption column absorption, the handling problems of wet mud are not considered yet.According to such method, control desulfurization is given up
Water is neutral meta-alkalescence, and process is adjusted without pH, causes that its oxidation efficiency is low, and aeration quantity is big.Cyclone separator is difficult to meet it
Water outlet is to the limitation of suspension requirement, while follow-up resin absorbing column may be blocked, do not mention yet adsorption column regeneration and
Handling problems.
The content of the invention
