Description
Technical field
The present invention relates to marine domestic sewage processing, in particular to a kind of MBR embrane methods marine domestic sewage processing system.
Background technology
The self cleaning of water is that organic matter is decomposed into inorganic matter and carbon dioxide by microorganism using the dissolved oxygen of water
Process, algae pass through photosynthesis absorbing carbon dioxide release oxygen.During Sewage from Ships is all ship's navigations
The sewage of discharge, a large amount of unprocessed Sewage from Ships can drastically consume the oxygen dissolved in water, destroy the self-purification of water
Effect and the ecological balance, while untreated sewage contains a large amount of malignant bacterias, polluted source, spreads disease.
Marine domestic sewage handling process is divided into three kinds by handling process at present：
First, biochemical process：Under conditions of having abundant oxygen, the same waste water of activated sludge that is trained, by active dirty
The biological chemistry action of mud removes organic matter, drops BOD5 (Escherichia coli) value, while by the absorption and agglutination of sludge
Solid Suspension adsorption is deposited.
1) sewage is entered in aeration tank by collection system, is disperseed by the air that blower fan blasts in the diffuser of aeration tank bottom
Into vesicle, these minute bubbles contact from while aeration pot bottom rising with sewage and active sludge intermixture, dissolve oxygen
And draw circulating for mixed liquor and be thoroughly mixed.Organic substance and activated sludge in sewage fully contact, by active dirty
Mud is attached, and inorganic matter is oxidized in the presence of bacterium, and remaining becomes the plasm that may make up bacterial cell, with the metabolism of bacterium
Activity is converted into energy and decomposition and consumption falls.
2) mixed liquor is separated into activated sludge and primary water after fully aeration into sedimentary deposit tank.The sludge of precipitation is returned by pump
Gas tank is delivered to, primary water enters in disinfection tank.
3) add after hypochlorite is disinfected to primary water and discharge in disinfection tank
Shortcoming：Process volumes are excessively huge, and space-consuming is big, and external hollow fiber ultrafiltration membrane easily blocks.
2nd, physico-chemical process：Add disinfectant after sewage is crushed, through separating treatment be primary water and sludge after wastewater disinfection,
By primary water venting, sludge is periodically drained.
1) sewage is entered in process tank by collection system, is mixed and is carried out disinfection with the disinfectant of addition after macerator pump crushes
Processing.
2) sewage after crushing and disinfecting is pumped into sedimentary deposit tank by filter screen by sewage.
Cleaning pump is ceaselessly cleaned to filter screen water filling to prevent from blocking.
3) sewage enters in sedimentary deposit tank, the solid in sewage is deposited on sedimentary deposit tank bottoms at different levels through multistage deposition, by dirt
Dredge pump is drawn back in process tank and handled again, and the sewage after clarification rushes down pump discharge by arranging.
Shortcoming：Poor processing effect, it need to separately add chemosterilant, not only take up an area, and danger close is stored on ship, easily to week
Enclose waters and produce secondary pollution, be unfavorable for environmental protection.
3rd, electrolysis：Sanitary sewage is set to flow through special electrolytic cell, the seawater in electrolyzing sewage produces NaClO, in by-product
Under the stirring of product gas is made, fully mixed with sewage, eliminate bacterium therein；Meanwhile the organic compound in sewage also exists
Oxidation Decomposition is into CO under electrolysis2And H20。
1) after sewage enters hold-up tank, after the crushing of macerator pump, electrolytic cell is entered with sea water mixing, by being electrolysed
Cheng Jinhang oxidation sterilizings.
2) sewage after being electrolysed enters overflow tank, continuation and NaClO progress oxidation sterilizing reaction caused by electrolysis in tank,
The sludge of precipitation is drawn back into hold-up tank, and the liquid after processing is discharged outboard.
Shortcoming：Early investment is big, and later stage operation expense is high.
Therefore, for above each method the defects of, is, it is necessary to work out a kind of high treatment effeciency, service life length, green peace
Entirely, lower-cost marine domestic sewage processing system.
