Mouth is less than the upper limb of floccule body filtering ponds 5, and connects with the inside of floccule body filtering ponds 5, thus when floccule body filtering ponds 5
When interior water level exceedes the top water inlet of quartz sand filter 51, can enter in quartz sand filter 51, and in water
Containing micro-sand conglomeration know from experience be separated from the water under the filtration of floccule body filtering ponds 5, make water be purified, and purify after water
Can discharge from the bottom outlet of quartz sand filter 51.The bottom outlet of quartz sand filter 51 and purification water water outlet
Pipe 6 connects, and does not connects with the inside of floccule body filtering ponds 5, thus the water after purifying can be via purifying water outlet pipe 6
Discharge.Purify water outlet pipe 6 and be provided with purification water outlet pipe electrodynamic valve 6a, by adjusting this purification water outlet pipe electrodynamic valve 6a
Can control to purify water outlet pipe 6 to open or close.
Described back purge system includes backwash cistern 71, backwash pump 72, backwash water inlet pipe 73 and backwash water outlet
Pipe 74.Backwash cistern 71 is gone out by the bottom of backwash pump 72 and backwash water inlet pipe 73 with quartz sand filter 51
The mouth of a river connects, and backwash water inlet pipe 73 is provided with backwash water inlet pipe electrodynamic valve 73a, by adjusting this backwash water inlet pipe
Electrodynamic valve 73a can control backwash water inlet pipe 73 and open or close, and therefore the water in backwash cistern 71 can be in backwash
Under the effect of water pump 72, bottom outlet by quartz sand filter 51 is sent to the inside of quartz sand filter 51, and warp
It is discharged in floccule body filtering ponds 5 by the top water inlet of quartz sand filter 51, thus is achieved that quartz sand filtration
The backwash of device 51, makes what quartz sand filter 51 filtered out to be punched in floccule body filtering ponds 5 containing micro-sand conglomeration body.
The bottom of floccule body filtering ponds 5 is located at by backwash outlet pipe 74, and connects with the inside of floccule body filtering ponds 5, this backwash
Outlet pipe 74 is provided with backwash outlet pipe electrodynamic valve 74a, can control instead by adjusting this backwash outlet pipe electrodynamic valve 74a
Flush out water pipe 74 to open or close, therefore by backwash enter in floccule body filtering ponds 5 containing micro-sand conglomeration body and water
Can be discharged, such that it is able to realize the recovery of micro-sand by backwash outlet pipe 74.In actual applications, described backwash dress
Put and can also include backwash cistern water inlet pipe 75；This backwash cistern water inlet pipe 75 connects with purifying water outlet pipe 6,
And this backwash cistern water inlet pipe 75 is provided with backwash cistern water inlet pipe electrodynamic valve 75a, by adjusting backwash water-retention
Pond water inlet pipe electrodynamic valve 75a can control backwash cistern water inlet pipe 75 and open or close；Water after purification enters purification water and goes out
Can be expelled directly out after water pipe 6, it is also possible to enter into backwash cistern 71 by backwash cistern water inlet pipe 75, think
Back-flushing processes provides water source.
Specifically, as it is shown in figure 1, this carrier potentiation flocculation is as follows with the workflow of sand filtration integral type quality purifying device for water:
(1) workflow of water is purified: aerobic fermentation tank outlet pipe 41 is adjusted to open mode, and by backwash water inlet pipe 73
It is adjusted to closed mode with backwash outlet pipe 74.The former water that with the addition of flocculant is flowed in coagulating basin 2 by former water water inlet pipe 1
Carry out coagulation, and the suspended thing in former water can quickly form initial flocculation body under the quickly stirring of coagulating basin blender 21,
And the water outlet of coagulating basin 2 is flowed in micro-sand filling pond 3 by top, junction overflow ducts.In micro-sand filling pond 3, micro-
Sand charging point 32 adds micro-sand in micro-sand filling pond 3, and under the quickly stirring of micro-sand filling pond blender 31, micro-sand
Wrapped up by initial flocculation body together with granule in water, be not broken into length, increase the floccule body that formation comprises micro-sand, and micro-sand adds
The water outlet in note pond 3 is flowed in inflow aerobic fermentation tank 4.In aerobic fermentation tank 4, along with the low rate mixing of aerobic fermentation tank blender 42, bag
Floccule body containing micro-sand is the most closely knit, and formed density bigger containing micro-sand conglomeration body, and the water outlet of aerobic fermentation tank 4 is by ripe
Change pond outlet pipe 41 to be flowed in floccule body filtering ponds 5.When the water level in floccule body filtering ponds 5 exceedes quartz sand filter 51
Top water inlet time, the water in floccule body filtering ponds 5 can enter in quartz sand filter 51, and in water containing micro-sand
Conglomeration cognition is separated from the water under the filtration of floccule body filtering ponds 5, makes water be purified, and the water after purifying is by quartz
The bottom outlet of sand defecator 51 is flowed into purification water outlet pipe 6.If purifying water outlet pipe 6 to be in open mode, that
Water after Jing Huaing can be exhausted directly to the external world；If backwash cistern water inlet pipe 75 is in open mode, then after purification
Water can be flowed into backwash cistern 71, think back-flushing process provide water source.
(2) workflow of backwash: backwash water inlet pipe 73 and backwash outlet pipe 74 are adjusted to open mode, and
Aerobic fermentation tank outlet pipe 41 and purification water outlet pipe 6 are adjusted to closed mode.Water in backwash cistern 71 can be in backwash
Under the effect of water pump 72, bottom outlet by quartz sand filter 51 is sent to the inside of quartz sand filter 51, and warp
It is discharged in floccule body filtering ponds 5 by the top water inlet of quartz sand filter 51, thus is achieved that quartz sand filtration
The backwash of device 51, makes what quartz sand filter 51 filtered out to be punched in floccule body filtering ponds 5 containing micro-sand conglomeration body；
Can be discharged containing micro-sand conglomeration body and water in floccule body filtering ponds 5 is entered into by backwash outlet pipe 74 by backwash,
Thus it is achieved that separation and the recovery of micro-sand.
Further, carrier potentiation flocculation provided by the present invention with sand filtration integral type quality purifying device for water at coagulating basin 2 with ripe
Change and between pond 4, be additionally arranged micro-sand filling pond 3, thus utilize the nucleation of micro-sand and increase the effect of flco proportion, Ke Yi great
The big process accelerating flocculation and coagulation, accelerates the formation speed of precipitation；Meanwhile, carrier potentiation provided by the present invention flocculation with
The quartz sand filter 51 that sand filtration integral type quality purifying device for water is additionally arranged after aerobic fermentation tank 4, this can be to containing micro-sand in water
Conglomeration body filters, thus reduces the use of medicament, micro-sand that recovery system is above added, it is not necessary to additionally carries out micro-sand and divides
From and backflow, decrease power consumption and operating cost.Compared with traditional settler, carrier provided by the present invention increases
Effect flocculation not only substantially increases hydraulic load with sand filtration integral type quality purifying device for water, shortens the sedimentation time, and reduces
Occupation of land usage amount, improve effluent quality, carrier potentiation flocculation the most provided by the present invention is clean with sand filtration integral type water quality
Gasifying device is a kind of to collect that carrier potentiation is flocculated, precipitates, filtered, micro-sand is recovered as the water treatment facilities of one, is particularly suitable for low
The process of float in temperature low-cloudy water.
As fully visible, the embodiment of the present invention not only increase hydraulic load, shorten the sedimentation time, reduce floor space, carry
High effluent quality, and eliminate the operation that settled sludge is carried out again silt particle separation and backflow, decrease power consumption,
Save operating cost, be therefore very suitable for low temperature and low turbidity water carries out purified treatment.
