Description

Ecological public lavatory
Technical field
The utility model relates to a kind of lavatory, particularly ecological public lavatory.
Background technology
At present, growing along with China's population, the quantity of public lavatory also increases thereupon.Common flush-type mainly be take as main in current public lavatory, and this type of lavatory water resource waste is serious, and take service person-time 500 people's times/day small-sized public lavatory is example, and 10 liters/person-time of average water supply volumes, just need to expend 5 tons of tap water for one day.Two kinds nothing but of sewage outlets, a kind of is to enter city planting ductwork, another is exactly nature seepage.All there is very large problem in these two kinds of blowdown modes, the former increases the operation burden of municipal wastewater treatment plant, and latter pollutes the environment.But also there is recent years a small amount of environment protection ecological type public lavatory to build, current bio-toilet is mainly divided into circulating flushing formula and exempts from water and rush two kinds of solid-liquid separatings, although be environment protection ecological type lavatory, but the defect that the recirculated water closet of present stage exists has a lot, as high in energy consumption, the complex process of sewerage treatment, equipment is various, treatment effect is general, needs with the recirculated water in tap water exchange system after use a period of time.Exempting from water, to rush the existing defect in solid-liquid separating lavatory be to have peculiar smell, and health, need to carry out follow-up harmless treatment to urine and ight soil not, and complex operation, also can cause secondary pollution.
Utility model content
The purpose of this utility model is to provide a kind of ecological public lavatory that can make sanitary wastewater efficiently process, recycle in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the ecological public lavatory that the utility model is designed, comprise the water tank, closet, grille well, biological septic tank, regulating reservoir, MBR anoxic pond and the equipment room that connect successively, above-mentioned water tank is connected with closet by water pipe, the sewage of closet enters grille well by soil pipe, in described grille well, is provided with grid; In biological septic tank, be provided with 2 above compartments, by soil pipe, be communicated with; In regulating reservoir, be provided with sewage pump, between regulating reservoir and water tank, be connected with water pipe; In MBR anoxic pond, be provided with aeration plate and membrane module, be provided with oxygen pump and suction pump in equipment room, described oxygen pump is connected with aeration plate by air hose, and the front end of described suction pump is connected with membrane module, and rear end is connected with water tank.
In concrete use procedure, water tank is connected with the closet in lavatory by water pipe, sewage in closet is collected and is entered grille well by soil pipe, sewage is through grid effect, remove most of solid floating thing and suspension, water outlet enters biological septic tank, and fecal sewage is in biological septic tank, through the effect of anaerobe, the COD content in water reduces greatly.Biological septic tank water outlet enters the homogenize adjusting that regulating reservoir carries out water quality and quantity, now sewage has met MBR anoxic pond flow condition, sewage in regulating reservoir enters MBR anoxic pond by sewage pump, in MBR anoxic pond, cultivate and have a large amount of acclimated microorganisms, under the metabolism of oxygen, aerobic microbiological of holding concurrently, each pollutant in sewage is removed.Finally by the filtration of membrane module, can accomplish Separation of Solid and Liquid completely, thereby guarantee that delivery turbidity is down to extremely lowly, simultaneously each pollutant in sewage is also further removed by the filtration of membrane module.So just water can be promoted in water tank and be started to recycle by suction pump.At this, MBR anoxic pond is known technology, and no further details to be given herein.
The ecological public lavatory that the utility model obtains, technique effect mainly contains following advantage:
1, water circulation use, saves tap water.Take service person-time 500 people's times/day small-sized public lavatory is example, and within one day, water is 5 tons, within 1 year, can save 1825 tons of tap water, and by 3.2 yuan/ton of calculating of townsfolk's water, within 1 year, saving water rate is 5840 yuan.
2, outlet effect is good, reaches < < urban sewage reutilization city miscellaneous water water quality > > (GB/T 18920-2002) standard.
3, running cost is low, only 0.4 yuan of ton water treatment expense.Under anoxic pattern, needed aeration rate is very low, than the cheap 1 yuan of left and right of bio-toilet ton cost of water treatment that adopts conventional MBR technique.
4, whole bio-toilet on environment without impact, odorless noiselessness during operation.
5, organic sludge zero-emission, mud is decomposed by autodigestion greatly, and sludge yield seldom, only needs 1 year discharge 1~2 inorganic mud (silt).
6, synchronous denitrification dephosphorizing.General sewage treatment process can only denitrogenation and dephosphorization separately carry out, MBR anoxic pond is utilized the gentle phosphorus reaction mechanism of eliminating of Anammox, has realized the efficient effect of synchronous denitrification dephosphorizing.
Accompanying drawing explanation
Fig. 1 is the structural representation of ecological public lavatory provided by the utility model.
In figure: water tank 1, closet 2, grille well 3, biological septic tank 4, regulating reservoir 5, MBR anoxic pond 6, equipment room 7, water pipe 8, soil pipe 9, grid 10, sewage pump 11, aeration plate 12, membrane module 13, oxygen pump 14, suction pump 15, air hose 16.
The specific embodiment
