Bidirectional rotational flow integral sewage water purifier of the present utility model is coagulation, flocculation, bidirectional rotational flow, suspension filtration and the mud thickening-purification technology technology that has designed sewage in same tank body, and the mode that adopts integrated and combination (20～28 minutes) at short notice realizes the stage purification of sewage.
One, the know-why of bidirectional rotational flow integral sewage water purifier
1, utilization direct current coagulation and little flocculation mechanism
Sewage needs dosing coagulant and coagulant aids according to water quality character and requirement in scavenging process, by the hydrolytic action generation Al of coagulating agent
3+, Fe
3+, H
+, OH
-Electrical neutralization, compression double electric layer reduces the § current potential, makes elimination of colloid stability, reduces the repulsion between colloidal solid, makes to bump between the particle and condense.Adding coagulant aids has been the effect of adsorption bridging, hydrolysis and polycondensation formation superpolymer by polymer substance have linear structure, colloidal solid has the intensive adsorption to this family macromolecule material, make and carry out adsorption bridging between colloidal solid, particle is become greatly gradually, form macroscopic flocs unit.The time of coagulating generally finished in 10～30 seconds.Flocculation time was generally finished in 4～6 seconds.According to this principle, the bidirectional rotational flow integral sewage water purifier is not established coagulation reaction tank, and coagulant dosage utilizes before the pump principle of negative pressure measure in water pump suction pipe and adds, and utilizes outlet conduit direct current coagulation behind pump impeller mixing and the pump.Measure again at the critical coacervation point of direct current pipeline and to add coagulant aids, finish little flocculation fast by pipeline and flow action, generally be controlled in 4～6 seconds the scope, overlong time, it is big that flocs unit becomes, when sewage enters down the eddy flow reaction zone at a high speed, certainly will be split brokenly by the shear force that subtracts of current, cause colloid flocculation to become to disperse steady state again.
2, following eddy flow mechanism
Sewage (generally is designed to 0.2～0.25MPa) and enters eddy flow reaction chamber under the cleaner at a high speed from inner cylinder top with tangential direction under certain pressure effect, do downward spiral motion, produce centrifugal force, it is big that the little flocs unit that forms in the sewage becomes rapidly, under the effect of centrifugal force and self gravitation, be thrown toward wall rapidly, and with the swirling flow effect is along sliding to taper bucket district under the bucket wall down, sewage is finished first class purification.The first class purification time is designed to 100～120 seconds.
3, forward spin flow mechanism
It is for the helical movement after to a certain degree downwards that sewage is finished first class purification, under the effect of pressure again along forming spiral motion between inner and outer barrel wall, sewage is under action of centrifugal force, continue to finish solid-liquid separation, flocs unit is thrown toward wall of the outer-rotor again, under slide to the mud district, for increasing eddy flow and separating effect, set up the concentric frustum of a cone plate (spacing 80～100mm of multi-turn at the forward spin flow reaction zone, inwardly tank body tilts 60 °), speed of rotation is accelerated, and centrifugal force strengthens, and makes waste water finish secondary purification.
Centrifugal force and particulate matter quality, the sewage quality, the relational expression between speed of rotation and rotation radius and gravity is:
C＝(M-M
0)V
2/R-----------------①
V＝2πr(n/60) -----------------②
P＝(M-M
0)g -----------------③
α＝C/P≈Rn
2/900 -------------④
Formula 1. in: M-granular mass (kg)
M
0-sewage quality (kg)
C-centrifugal force
V-rotation round linear velocity (m/s)
R-rotation radius (m)
Formula 2. in: n-rotating speed (r/min)
Formula 3. in: P-in gravity field, the suffered gravity of particle (kgf)
G-universal gravity constant (9.81m/s
2)
Formula 4. in: α-separating factor
From formula 1. as can be known, centrifugal force and rotation radius are inversely proportional to, and with square being directly proportional of rotational line speed, are directly proportional with granular mass, granular mass is big more, rotational line speed is fast more; Rotation radius is more little, and then centrifugal force is big, good separating effect, but more open for the flocs unit particle of colloidal solid formation, speed of rotation is too fast, and flco is then easily broken, and quality reduces, the separating effect variation, wastewater purifying efficiency is also poor; And rotation radius is too small, and processing power is little, is unfavorable for the industrialization use, therefore in the centrifugal separation processes, must take into account and select suitable rotational line speed, rotation radius, guarantee centrifugal force greater than gravity, increase separating factor as far as possible, improve separating power and decontamination effect improving.
In the flco centrifugation, separating particles granularity experimental formula is:
In the formula: D-separation size (μ m)
D
1-cleaner outside diameter (cm)
D
2-diameter of outflow tube (cm)
D
3-water inlet pipe diameter (cm)
P-intake pressure (0.2～0.25MPa)
M-pellet density (kg/m
3)
M
0-waste water density (kg/m
3)
In centrifugation, the sewage inlet velocity is controlled at 3.5～6.0m/s, and following eddy flow reaction zone cylindrical shell radius is controlled in 0.2～0.7m scope according to handling water yield size, and cleaner cylindrical shell radius is controlled in 0.8～2.0m scope.
4, suspension work principle of filter
Sewage still has a small amount of flco to fail to separate behind secondary purification in the sewage, therefore design filtrating area, the filtrating area supporting layer adopts stainless steel filtering net (30 order), filtrate is selected multistage EPS expanded plastic filter pearl of joining for use, particle diameter 0.8～1.2mm, and tap density is 80-100g/cm
3, voidage 0.4～0.5, specific surface area are 650～850m
2/ m
3Filtrate suspends in water, filtering velocity is 8-15m/S, suspended filter material is carried out dynamic filtration by means of last swirling flow campaign under centrifugal action, the medium and small flco of sewage has been accelerated the collision between pedesis and filtering material particle, makes little flco with certain mass throw laminar surface to the filtrate along the current tangential direction, produces coalescent simultaneously under the effect of chemical bond, Van der Waals force, flocculation, and be thrown toward the wall supreme cyclone reaction district that glides, quicken sedimentation and separate as contact medium.By means of action of centrifugal force, increased collision and frictional force between the suspended filter material particle, the impurity that adheres to the surface is easily peeled off, so the difficult obstruction of filtrate, backwashing period is long.The semisphere draining filter (ABS material) of filtrate top-level design some amount is installed on the support steel plate.For making backwash effect good, on the support steel plate, design the sewage backwash mesh of some amount, mesh adopts 30 order Stainless Steel Cloths, and purpose is that the long-term sedimentary a small amount of suspended substance of clear water zone is rinsed well, avoids influencing the water outlet effect.
5, mud concentrates mechanism
At cleaner lower end design taper sludge bucket, awl bucket angle is 55～60 °, there is a muddy liquid level sludge bucket middle and upper part, sludge concentration is about 1-3%, and under the cohesion effect, particle colony is combined into one, the geostationary position of each self-sustaining is the stratiform sedimentation, in the sludge bucket middle and lower part, sludge concentration is higher relatively, and grain spacing is from little, particle is in contact with one another, support mutually, at cleaner internal water pressure and upper strata particle gravity, under the effect of centrifugal force and structural distortion, intergranular pore water constantly is extruded the interface, granule density improves constantly and is concentrated densification and finishes compression precipitating, and final mud is discharged from sewage draining exit, and its concentration can reach 6～12%.
