Description
Technical field
The utility model is related to technical field of sewage, more particularly to a kind of rural domestic sewage treatment system.
Background technology
At present, the most village of China is also without drainage pipeline networks and sewage disposal system, and production and living sewage is arbitrarily arranged
Put, cause the severe contamination of rural area water body, surrounding enviroment are constituted and adversely affected, periphery masses' safe drinking water is threatened, with agriculture
The fast development of village's economy, growth in the living standard causes domestic sewage in rural areas discharge capacity to increase, and status of rural is increasingly disliked
Change.Existing domestic sewage treatment process species is although more, such as A2/O techniques, membrane bioreactor, biological fluidized bed, still
Compared with municipal sewage treatment, rural area is more dispersed, and water supply standard is than relatively low per capita, and in the morning, noon, the dusk
Period compares concentration, water greatly with water, but very small to period at night water consumption, and period in morning water consumption is substantially zeroed,
Water fluctuation is very big, occurs low discharge at night or even the situation of zero delivery occurs, microorganism is in dry state, causes
The unstable or even paralysis of existing technical operation;Because pollutant burden is relatively low, treatment effeciency is low when using prior art
Under;Because existing process technology is complex, it is desirable to have technical professional is run and maintenance management, in remote agriculture
Realize to village more difficult.
The content of the invention

Filtrate is made up of the less gravel of particle diameter and the larger gravel of particle diameter.It is respectively water distribution layer, filter layer, supporting layer from top to bottom.
Water distribution layer is made up of the larger gravel of particle diameter and water-locator, and the space between big particle diameter gravel is larger, can sufficiently be connect with air
Touch, preferably carry out Aerobic biological process.Filter layer is then made up of thinner gravel, is mainly inhaled by physical absorption, precipitation, chemistry
Attached and/or biological chemistry action is removed to the solvable or gluey pollutant in sewage;Supporting layer is then by larger gravel
And water collector is constituted.Gravel layer plays support to the gravel on upper strata, while protecting water collector, prevents tiny gravel from entering collection
Hydrophone results in blockage.
Further, artificial swamp is current wetland, and preferably hydraulic surface loading is 0.2~0.5m3/ (㎡ d), waterpower
Residence time is 1~3d, and final outflow water is better than the class water of earth's surface V, and the filler of artificial swamp uses sandstone, and emergent aquactic plant selects reed
Reed.
In use, treatment sewage enters the septic tank of pretreatment structures from water inlet pipe, by septic tank, sanitary sewage
In most suspension obtain precipitation process, under anaerobic and hydrolyze larger molecular organicses, and obtain stabilizing dirty
Mud is deposited in pretreatment structures, and the sewage after septic tank is handled is entered ring biofilter (WRBF) by grille well
Intake pool.Sewage and the recirculated water mixed diluting after processing in intake pool, are pumped to sand filter by reflux pump, led in sand filter
Cross water-locator and sewage is equably distributed to sand filter top layer, the cycle of operation of water-locator is interval 25min water distributions 5min.By
Water after sand filtration processing is collected in sand filter bottom by water collector, is flowed into regulating reservoir by Action of Gravity Field, is then passed through check-valves
Flow into intake pool, so circulation.When water increases, the water level of regulating reservoir rises, and starts to lead to after water level exceedes downflow weir
Overregulate and arranged outside the delivery port in pond.Obtained by the biochemical action of the Physical entrapment of circulating biological filter tank (WRBF) filtrate, microorganism
To secondary effluent, finally the secondary effluent is entered by the delivery port of regulating reservoir and handled in artificial swamp, by planting
The absorption of thing, finally gives the higher discharge water of water quality and is discharged from drainpipe, so as to reach sewage disposal purpose.
As can be seen here, present embodiments provide a kind of suitable for rural area dispersed miniature domestic sewage processing system, regulation
The setting of downflow weir in pool unit, realizes automatically adjusting for system water, with control it is simple, sensitive the characteristics of, effectively
Ground solves the drawbacks of country sewage water is unstable;Water inlet pool unit realizes the mixed diluting of water, and regulating reservoir reclaimed water is led to
Cross after check valve flows into intake pool, with water mixed diluting and continue to pump to sand filter, realize the circular treatment of sewage, processing effect
Fruit is preferably.The sewage disposal system is simple to operate, stable, treatment effeciency is high;And sewage disposal system floor space is small,
Operation energy consumption is low, operating cost is low, and the ecological effect of artificial swamp is good.
It should be noted that the septic tank in the utility model is not limited to coagulation with the grille well and constructed
Thing, other grades pretreatment structures, as long as most suspension in sanitary sewage can be made to obtain precipitation process i.e.
Can;Similarly grille well is also not limited to using the basket grid maintained easily, other identical function grille wells;In addition, people
Work wetland is not necessarily limited to current wetland, and other can realize that water outlet all may be used better than the wetland of the class water of earth's surface V.
Apply specific case in this specification to be set forth principle of the present utility model and embodiment, the above is real
The explanation for applying example is only intended to help and understands method of the present utility model and its core concept;Simultaneously for the general of this area
