Abstract
The invention discloses a marine domestic sewage treatment unit, comprising an aeration cabinet (1), a contact cabinet I (2), a contact cabinet II (3), a settling tank (4) and a disinfection clean water cabinet (7); a membrane module is arranged between the settling tank (4) and the disinfection clean water cabinet (7); in the invention, the membrane module including a membrane separation device and an ultraviolet light disinfection device is additionally arranged on the basis of the existing biochemical technology sewage treatment unit, the arrangement of the membrane module updates the original sewage treatment standard and is suitable for new requirements formulated by new international agreement to the marine sewage discharge standard; a back flushing water interface is arranged on the membrane separation device for back flushing the outer surface of a fiber pipe in the membrane separation device, so as to prevent 0.2mum holes on the surface of the fiber pipe from being blocked by sludge and effectively ensure to not affect sewage treatment capacity. A secondary filter can further filter sewage better. The method saves cost, the membrane separation device can be used for a long time without replacement, and discharge water quality is hard to be out of limits.
Description
Technical field:
The present invention relates to a kind of marine sewage treatment system.
Background technology
At present, known marine sewage treatment system adopts biochemical process to handle substantially, promptly through the sewage of oxygenation with the certain speed filler of flowing through, make and cover with microbial film on the filler, sewage contacts with microbial film, under biomembranous effect, thereby aerobic bacteria is constantly engulfed organism sewage is purified.
Because must formally implement " the MARPOL73/78 pollution convention " that emission request proposed about the Sewage from Ships treatment unit that Marine Environmental Protection Committee of International Maritime Organizaton passed through on October 13rd, 2006 from January 1st, 2010, the discharge index of original device sewage disposal flow process far can not satisfy the new sewage drainage standard that new " pact " announced.
| Former discharge index | New pact discharge index | |
| Coliform (M.O.N) geometrical mean | ≤ 250/100mL | ≤ 100/100mL |
| Suspended solids total amount (S.S) geometrical mean | ??≤50mg/L | ??≤35mg/L |
| Five-day BOD (BOD5) | ??≤50mg/L | ??≤25mg/L |
| Chemical oxygen demand (COD) (COD) | ??≤125mg/L | ??≤125mg/L |
| PH value | ??6-9 | ??6-8.5 |
Summary of the invention
The invention provides a kind of marine sewage treatment system, can satisfy the discharge index of new " pact ", and cost is low, long service life.
The present invention has adopted following technical scheme: a kind of marine sewage treatment system, comprise aerate cabinet, contact cabinet I, contact cabinet II, sump tank and sterilization clear water cabinet, and be provided with membrane module between described sump tank and sterilization clear water cabinet.
Be provided with apparatus for ultraviolet disinfection between described sump tank and membrane module; Be provided with apparatus for ultraviolet disinfection between described sump tank and sterilization clear water cabinet; Described sump tank is by rejecting pump and secondary filter is connected; Described membrane module is provided with condensed water interface and backwashing water interface; Be equipped with valve on the bottom pipe of described aerate cabinet, contact cabinet I, contact cabinet II, sump tank, sterilization clear water cabinet and membrane module.
The present invention has following beneficial effect: the present invention has added membrane module on the basis of existing biochemical process waste disposal plant, be membrane separation unit and apparatus for ultraviolet disinfection, this assembly is upgraded to original effluent-disposal standard peculiar to vessel, can adapt to the new demand that new " pact " formulated sewage drainage standard peculiar to vessel.Membrane separation unit is provided with the backwashing water interface, and membrane separation unit internal fiber tube outer surface is carried out back flushing, prevents that its surperficial 0.2 μ m aperture is not subjected to sludge blockage, guarantees that effectively sewage load is unaffected.Secondary filter can better filter sewage.This method is saved cost, but the membrane separation unit life-time service need not replacing, and discharging water quality is difficult for exceeding standard.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Embodiment
In Fig. 1, the present invention is a kind of marine sewage treatment system, comprise aerate cabinet 1, contact cabinet I2, contact cabinet II3, sump tank 4, membrane module, sterilization clear water cabinet 7, membrane module is made up of apparatus for ultraviolet disinfection 5 and membrane separation unit 6, aerate cabinet 1 successively with contact cabinet I2, contact cabinet II3, sump tank 4, apparatus for ultraviolet disinfection 5, membrane separation unit 6 and sterilization clear water cabinet 7 and communicate.Described membrane separation unit 6 is provided with condensed water interface and backwashing water interface, the backwashing water interface can carry out back flushing to membrane separation unit 6 internal fiber tube outer surfaces, be connected with in turn between described sump tank 4 and the apparatus for ultraviolet disinfection 5 and reject pump 9 and secondary filter 10, secondary filter 10 links to each other with the PLC controller.The place, input aperture of described aerate cabinet 1 is connected with macerator pump 8, the top of aerate cabinet 1 is provided with fire water inlet 12, be provided with ventilation mouth 13 at the top of aerate cabinet 1 between the cabinet I2 with contacting, described aerate cabinet 1, contact cabinet I2, contact cabinet II3, the bottom of sump tank 4 and sterilization clear water cabinet 7 is provided with pipeline parallel with one another, pipeline is communicated with side of a ship outer vent by emptying pump, described aerate cabinet 1, contact cabinet I2, contact cabinet II3, sump tank, be equipped with valve 11 on the pipeline of the bottom of membrane separation unit 6 and sterilization clear water cabinet 7, described aerate cabinet 1, contact cabinet I2, contact cabinet II3 with in establish pipeline I15 and be connected with air pump, be provided with the recoil loop between sump tank 4 and the aerate cabinet 1, sump tank 4 is communicated with by between recoil loop and the aerate cabinet 1, sterilization clear water cabinet 7 tops are provided with grey water inlet, and are provided with anti-overflow head piece 14.
Sewage of the present invention flows into aerate cabinet 1 after macerator pump 8 is pulverized, mix with active sludge, enters filler in the two-stage contact cabinet through oxygenation, contacts with microbial film.Wherein organic pollutant is adhered to by microbial film and clears up, and generates CO2 and water.Sewage after two-stage contact cabinet microbial film is handled enters sump tank 4 precipitations, water after the clarification flows into apparatus for ultraviolet disinfection after secondary filter 10 filters, enter membrane separation unit through the water after the sterilization, after membrane separation unit internal fiber pipe filters, clear water flows out by fibre pipe is inner, enter sterilization clear water cabinet 7, at last by fluid level controller discharging outboard regularly, macrobead shape sewage material (concentrated solution) is intercepted outside fibre pipe sidewall 0.2 μ m aperture, drain into the bilge (sump tank) through the concentrated solution mouth, recirculation is filtered.
