Background technology
According to the MEPC.159(55 of International Maritime Organizaton) resolution requirement, need meet its discharge water quality requirement at the sanitary sewage of relevant marine site discharge, emission standard is as follows:
Thermotolerant coliform geometric mean≤100/100ml,
Suspended solids total amount≤35mg/l,
Five-day BOD≤25mg/l,
Chemical oxygen demand (COD)≤125mg/l,
PH value is between 6 and 8.5.
Marine sewage treatment system is to use biochemical process to process a kind of equipment of domestic water and lavatory drain fecal sewage on boats and ships.It comprises: aerate cabinet, sump tank, self-cleaning device, disinfection cabinet.In equipment, the organic substance taking aerobic bacteria in main activated sludge absorption sewage, under aerobic condition, organic substance is oxidized fully, decomposes, and becomes harmless carbonic acid gas and water, then passes through the subsequent disposal such as precipitation, sterilization, sterilization, make it to reach international emission standard, drain into outboard.
Marine sewage treatment system utilizes aerobic bacteria for the organic substance in main activated sludge absorption sewage, and this is a kind of technology generally having used of maturation.But in sewage treatment process, because sanitary sewage velocity of flow is slow, the impurity, the dirt that contain are more, the pipeline that easily results in blockage, and easy to clean not, cause pipe-line maintenance cost greatly to increase.And swiftly flowing liquid can produce negative pressure, increase liquid flow velocity, be a kind of in the ripe prior art using of other field, be just not yet applied at present marine domestic sewage treatment system.
Summary of the invention
The purpose of this utility model is to address the deficiencies of the prior art, on the equipment of the marine sewage treatment system that maturation is used, additional a set of vacuum collection device, increase the kinetic energy of sewer line liquid-flow, make mobile sewage convert swiftly flowing liquid to, reduce line clogging, water-saving when joint, the end-use performance of raising equipment.
The utility model is achieved in that the vacuum collection device in a kind of marine domestic sewage treatment system, described marine domestic sewage treatment system comprises aerate cabinet, sump tank, disinfection cabinet, self-purifier, water circulating pump, discharge water pump, high pressure positive blower, life sewage storage, active sludge and microorganism, it is characterized in that: described marine domestic sewage treatment system is also provided with vacuum collection device, be arranged on the casing side of marine domestic sewage case; Described vacuum collection device is made up of a water pump and pipeline, valve, and before valve is arranged on pump intake, water pump is propulsion source, extracts sanitary sewage in life sewage storage bottom, accelerates sanitary sewage and flows at pipeline internal recycle.
The pipe outlet of described vacuum collection device is provided with a nozzle, described nozzle is located in the enclosed housing of sanitary sewage ingress, sanitary sewage box top, enclosed housing is also connected with the pipe outlet that attracts lavatory, sanitary sewage, convert mobile sanitary sewage to swiftly flowing liquid, swiftly flowing liquid produces negative pressure in the ingress of life sewage storage, accelerate to flow, reduce line clogging, and discharge outboard.
Water pump is drawn sewage from life sewage storage bottom, and through the pumping of water pump, current accelerate, and sewage enters casing again from the top of sewage box body, forms like this circulating of current.
The beneficial effects of the utility model are: the utility model is the application on marine sewage treatment system by vacuum collection device, can increase the kinetic energy of drainage flow, reduce line clogging, reduce maintenance cost.Water pump is stirring-up sewage constantly, makes the solid matter fast-crushing in sewage, accelerates the oxidation of organic substance, and utilizes the negative pressure that vacuum collection device forms to reclaim sewage, saves the water consumption while flushing, and aboard ship fresh water is valuable.The utility model has reduced water consumption, has also reduced the working load of marine domestic sewage treatment system simultaneously, makes whole equipment improve usefulness.
Brief description of the drawings
Fig. 1 is the schematic diagram that is related to of rate of flow of fluid and pressure.
Fig. 2 is the utility model structural representation.
In figure: 1, vacuum collection device; 2, life sewage storage; 3, water pump; 4, nozzle; 5, enclosed housing; 6, recirculated water; 7, valve; 8, attract the pipe outlet of lavatory, sanitary sewage.
Embodiment
With reference to the accompanying drawings 1, the principle that negative pressure produces:
According to bernoulli principle, the mechanical energy of fluid is conservation.
Expression formula: 1/2pV
2+ pgh+P=constant,
V-velocity of flow,
P-fluid density,
G-universal gravity constant,
The residing height of h-fluid,
The pressure that P-fluid is suffered,
According to this equation reasoning, popular says: fluid in same density, highly, under the condition of universal gravity constant.Flow velocity is little, and pressure is just large.Flow velocity is large, and pressure is just little.Flow velocity is inversely proportional to pressure.
Can get information about from accompanying drawing 1, when liquid from inlet streams to exit procedure, run into the caliber of two different cross sections, the liquid of same flow flows in different tube diameters, the flow velocity V2 in the little cross section caliber of flow velocity V1 < in large cross section caliber.The pressure of corresponding fluid is exactly P1 > P2.
With reference to the accompanying drawings 2, the utility model is in conjunction with above-mentioned principle, and at the sewage inlet end of marine sewage treatment system, vacuum collection device 1 of design and installation, is arranged on the casing side of marine domestic sewage case 2.Vacuum collection device is made up of a water pump 3 and pipeline, valve 7, and before valve 7 is arranged on water pump 3 water-ins, water pump 3 is propulsion source, extracts sanitary sewage in life sewage storage 2 bottoms, accelerates sanitary sewage and flows at pipeline internal recycle, forms recirculated water 6.
The pipe outlet of vacuum collection device 1 is provided with a nozzle 4, nozzle 4 is located in the enclosed housing 5 of life sewage storage 2 sanitary sewage ingress, top, enclosed housing 5 is also connected with the pipe outlet 8 that attracts lavatory, sanitary sewage, convert mobile sanitary sewage to swiftly flowing liquid, swiftly flowing liquid produces negative pressure in the ingress of life sewage storage, accelerate to flow, reduce line clogging, and discharge outboard.
The utility model working process is as follows:
Start water pump 3 and work, water pump 3 gives sanitary sewage increases kinetic energy, sump pump is hoisted, simultaneously also by solids pulverizing, stirring, aeration in sewage.
Sewage, along Flows, narrows suddenly through nozzle 4 runners, and mobile sewage converts swiftly flowing liquid to, and liquid sprays in casing from the sanitary sewage entrance of sanitary sewage upper box part fast.In this process, near nozzle 4, produce negative pressure.
