Abstract
The utility model discloses a marine sewage treatment unit which comprises an aeration cabinet (1), a contact cabinet I (2), a contact cabinet II (3), a settling cabinet (4) and a disinfection clean water cabinet (7), wherein a membrane module is arranged between the settling cabinet (4) and the disinfection clean water cabinet (7). The membrane module including a membrane separating device and an ultraviolet ray disinfection device is additionally arranged on the existing biochemical sewage treatment unit, upgrades the original marine sewage treatment standard, and can meet the new requirement in 'new convention' of the marine sewage discharge standard. The membrane separating device is provided with a back washing water connector which is used for back washing of the outer surface of a fiber pipe inside the membrane separating device, thus preventing small holes of 0.2 mum on the surface thereof from being blocked by sewage sludge, and effectively guaranteeing the sewage treatment amount not to be influenced. A fine filter can better filter the sewage. The method can save cost, the membrane separating device can be used for a long term without replacement, and the quality of discharged water does not easily exceed the standard.
Description
Technical field:
The utility model 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 utility model provides a kind of marine sewage treatment system, can satisfy the discharge index of new " pact ", and cost is low, long service life.
The utility model 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 utlity model has following beneficial effect: the utility model 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.
