Specific embodiment
As shown in Figure 1-3, the suspension media layer filtration system based on hydraulic flow state stratification, including filter device 1, reflux pump
12, water inlet medicine system 14 and main body rack 15；The filter device 1 is set on main body rack 15, and main body rack 15 is installed
In on ground；The water inlet medicine system 14, reflux pump 12 and filter device 1 constitute circulation loop.
The filter device 1 includes effluent weir 2, water outlet 3, overflow port 4, refluxing opening 5, evacuation port 6 and water inlet 7；Institute
It states and is equipped with effluent weir 2 inside filter device 1, effluent weir 2 connects water outlet 3, and overflow port 4 is arranged in 1 side of filter device；It is described into
The mouth of a river 7 is located at 1 two sides of the bottom of filter device；
1 bottom of filter device is equipped with refluxing opening 5 and evacuation port 6；The refluxing opening 5 passes through reflux pump 12 and water inlet dosing system
14 connection of system；The evacuation port 6 is connected to drainage system by evacuated tube.
The height of the overflow port 4 is higher than effluent weir 2.
The effluent weir 2 is set on the inside of 1 upper end of filter device, and is connected with 1 upper half inner wall of filter device, with
1 inner wall of filter device surrounds the box space of a upper opening；The effluent weir 2 is sawtooth weir or horizontal weir.
In a ring, inner bottom surface is symmetrical arranged water outlet 3 to the effluent weir 2, and water outlet 3 extends to filtering dress by pipeline
Set the water outlet of 1 outer wall.
2 section of effluent weir is L-shaped, and L shape side is fixed in 1 upper inside wall of filter device, with filter device 1
Form "u"-shaped groove.
The water inlet 7 is located at 1 bottom end two sides of filter device；Intake direction and filter device 1 be in it is tangentially-arranged, two sides into
The mouth of a river 7 is arranged symmetrically, and is connected by pipeline with water inlet medicine system 14.
The internal diameter of 1 top half of filter device is gradually expanded from bottom to top, and lower half portion is inverted cone infundibulate.
The water inlet medicine system 14 includes medicine-adding bin 8, intake pump 9, pipe-line mixer 10, hybrid electric motor 11 and water inlet pipe
13；The water inlet pipe 13 is connect with intake pump 9, and intake pump 9 is connect with pipe-line mixer 10, pipe-line mixer 10 and filter device
1 connection；
The medicine-adding bin 8 is connect with pipe-line mixer 10 and reflux pump 15 respectively；Hybrid electric motor is equipped at the top of the medicine-adding bin 8
11, hybrid electric motor 11 is connect with agitating device, and agitating device is set to inside medicine-adding bin 8.
The water inlet medicine system 14 includes pipe-line mixer 10；Described two water inlets 7 connect with pipe-line mixer 10
It connects.
When the invention works, intake pump 9 enters pipe-line mixer 10 from the extraction treatment sewage of water inlet pipe 13, mixed in pipeline
Sewage is mixed with the medicament after mixing in clutch 10, is entered in filter device 1 by water inlet 10.Water inlet is filled with medicament
Divide mixing, is the precondition to form suspension media layer.Since water inlet 7 there are 2,1 two sides of filter device are located at, are entered
The water flow of water inlet 7 can tangentially form vortex, be conducive to that flocculation reflection occurs after mixing into water with medicament, and form upper lower leaf
Suspension media layer.
Then, water inlet medicine system 14 to filter device 1 be fed, 1 main body upper half rounding stage body of filter device, internal diameter by
It is gradually expanded upwards down, the upflow velocity of pending water can be gradually reduced, control the suspension media layer height and density of formation；Under
Half portion is in inverted cone infundibulate, can will be back to and be added by refluxing opening 5 after the remaining suspension dielectric layer accumulation of impurities to settle down
Medicine system 14 passes through the unified discharge system of evacuation port 6.
Medicament in the water inlet medicine system 17 is mainly flocculant or the medicament with same function, by medicament with
Mixing, the flocculation of water inlet form suspension media layer, and the hydraulic flow state collective effect formed with the structure of filter device 1 can be formed
Suspension media layer with filtering function is effectively filtered and is removed phosphate to water inlet.At this point, by the liquid of filter layer
Body enters effluent weir 2, and is discharged by water outlet 3；When liquid height is higher than effluent weir 2, overflow is carried out by overflow port 4；
The water being discharged through water outlet 3 enters subsequent decontamination system or discharge water body, before the overflow water being discharged through overflow port 4 is back to system
End.
Remaining suspension dielectric layer impurity positioned at the sedimentation of 1 bottom of filter device is back to dosing by the effect of reflux pump 12
Bucket 8 reduces device medicine consumption while guaranteeing suspension media amount in filter device 1, saves operating cost.The evacuation port 6 is logical
It crosses evacuated tube and is connected to drainage system.
