Description
Technical field
The present invention relates to environmental technology field, particularly relate to a kind of marine domestic sewage treatment system.
Background technology
Sewage from Ships refers to the waste water being formed by the contained animal everyday life of crewman, passenger and boats and ships.Conventionally the waste water and the refuse that come from boats and ships toilet, consulting room, loading Live Animals place are called to " Heisui River ", and waste water and the refuse located from kitchen, laundry and washroom etc. are called to " buck "., can there are a series of biochemical actions in the unprocessed water surrounding that enters arbitrarily of Sewage from Ships.The natural purification process of water surrounding be bacterium and other microorganisms utilize dissolved oxygen in water by organic substance decomposing the process for inorganics and carbonic acid gas.Algae absorbing carbon dioxide, makes self growth by photosynthesis, emits oxygen simultaneously.Although this natural purification process carries out very slowly, this process remains a kind of equilibrium process, and the determinative that maintains this balance is the content of dissolved oxygen.If a large amount of sanitary sewages row people water surrounding, will cause the content of oxygen in water to reduce, destroy natural purification process and the eubiosis of water surrounding, changed the ecological characteristic of water surrounding, caused the dead or migration of the animals such as fish in water surrounding.Nutritive salt in Sewage from Ships enters after water surrounding, in the time of its too high levels, just can make algae excessive ground Growth and reproduction, there is eutrophication, the content of oxygen in water is reduced, produce anaerobic condition, make the aerobic colony in the animal and plant group of ocean, as fish are replaced by the rudimentary soft insects of anaerobism colony.And, in the undressed fecal sewage of every 1mL, contain approximately millions of bacteriums, wherein majority is malignant bacteria, infects multiple infectious intestinal disease.If fecal sewage kills malignant bacteria without abundant processing, it will polluted source, and propagates this class disease, just this can produce and threaten the mankind's health.
