Description
Technical field
This application involves sewage treatment fields, more particularly to a kind of equipment for separating liquid from solid and its application.
Background technique
During sewage treatment, generally includes physical reaction and be separated by solid-liquid separation two big steps, that is, is so-called mixed
Solidifying depositing technology.In coagulation-settlement process, coagulation or coagulation process, that is, physical reaction are primarily referred to as adding coagulation into sewage
Hydrolysis, polycondensation reaction are completed in agent under certain hydraulics, make de- steady and cohesion the process of the colloidal dispersion system of sewage, should
Process is divided into two stages of mixing and particle coagulation again.Mix stages are to instigate the medicament including coagulant of investment rapid, equal
It is spread in sewage evenly, to create good hydrolysis condition, this stage is mixed using fast, i.e., quickly stirs and evenly mixs, make
Medicament is rapid, evenly dispersed.After the particle coagulation stage refers to completion mix stages, colloid mutually touches under certain hydraulics
It hits, assemble or adds and help on a small quantity solidifying, to form the process of larger cotton-shaped particle, this stage using slow mixed, that is, is stirred at low speed mixed
It is even, to ensure the reaction effect of medicament.Involved in entire coagulation process, the 1. property of water-borne glue body, 2. coagulant is in water
Hydrolysis, the 3. interaction of colloid and coagulant.
Object handled by coagulation, small suspended matter and colloid mainly in sewage.Big suspended matter is due to by weight
The effect of power and sink, can with precipitating the methods of remove.But the small suspended matter of nominal particle size and colloid micelle, it can be
Keep dispersion suspended state will not natural subsidence even if standing tens of hours or more for a long time in sewage.This is because small outstanding
Floating object particle and micelle have " stability ".The mechanism of coagulation is not fully apparent from yet so far, because there are many factor that it is related to, such as
The ingredient and concentration of impurities in water, water temperature, the pH value of water, the property of basicity and coagulant and coagulation condition etc..But it summarizes
Come, the mechanism of coagulation there are three broad aspects:
(1) compression double electric layer acts on
Colloidal impurity micelle in sewage can maintain stable dispersion suspended state, mainly due to the ∫ electricity of water-borne glue grain
Position is higher.As can eliminating or reducing the ∫ current potential of micelle, it is possible to make micelle collision coalescence, loss of stability.It adds in water
The coagulant of electrolyte property is i.e. up to this purpose.Such as negatively charged clay micelle in natural water, in investment molysite or aluminium
After the coagulant such as salt, a large amount of cations that coagulant provides can pour in colloid diffusion layer even adsorption layer.Because glue core surface
Combined potential is constant, increases the cation concentration in diffusion layer and adsorption layer, is just thinned diffusion layer, and ∫ current potential reduces.When largely just
Ion pours in adsorption layer so that when diffusion layer completely disappears, and ∫ current potential is zero, referred to as isoelectric state.Under isoelectric state, between micelle
Electrostatic repulsion disappears, and micelle most easily coalesces.In fact, as long as ∫ current potential is down to a certain degree and makes the energy repelled between micelle
When amount is less than the kinetic energy of micelle Brownian movement, micelle begins to generate apparent coalescence, and ∫ current potential at this moment is known as critical potential.
For micelle because ∫ current potential reduces or eliminates the process so that loss of stability, referred to as micelle is de- steady, takes off steady micelle and mutually coalesces, claims
For cohesion.
(2) adsorption bridging acts on
After trivalent aluminium salt or molysite and the solidifying agent of other macromolecule rods are dissolved in water, macromolecule is formed through poly-condensation and hydrolysis
Polymer has linear structure.This kind of high molecular polymer can by micelle strong adsorption, because its lineal measure is larger, when it
After a certain micelle is adsorbed in one end, the other end adsorbs another micelle again, carries out adsorption bridging between two micelles apart from each other, makes
Gradually knot is big for grain, forms macroscopic coarse floccule body.It is this to be acted on by polymer substance adsorption bridging and keep particle mutual
The process of bonding, referred to as flocculates.
(3) the net effect of catching
Trivalent aluminium salt or molysite etc. hydrolyze and generate sediment.These sediments can collect volume, net during settlement
The particles such as the colloid in water are caught, micelle is bonded.
Usually the cohesion for making the mutual condensation process of colloidal solid by Effect of Electric Double Layer and pass through high molecular polymer
Adsorption bridging effect and make the flocculation of the mutual bonding process of colloidal solid, collectively referred to as coagulation.Therefore medicament is added into sewage,
The mixing of sewage and medicament is carried out, so that the colloidal substance in sewage be made to generate this combined process of agglomerating and flocculate as coagulation
Process.Coagulation process precipitates small suspended matter and colloid aggregation at coarse particle, is separated from water, obtains sewage
Purification.
In existing technology, device or structure used by coagulation process are coagulating basins, by structure type be broadly divided into every
Plate flocculation basin, folded plate flocculator, mechanical flocculation basin, grid flocculation pool of grid strip, rotational flow flocculation tank and perforation rotational flow flocculation tank etc..
Partition flocculation basin refer to water flow with certain flow rate between partition by completing the structures of flocculation process, such as
Shown in Fig. 1, the flocculating effect of partition flocculation basin is unstable, and pond is big, is commonly used in large and medium-sized water factory, and for small-sized water
Factory, water is too small, and partition room is away from excessively narrow, inconvenience construction and maintenance.
Folded plate flocculator refer to water flow with certain flow rate between folded plate by completing the structures of flocculation process, press
Folded plate flocculator can be divided into vertical-flow and flat flow according to water (flow) direction, generally use it is vertical-flow, as shown in Fig. 2, it is by partition
The plate partition of flocculation basin is changed to the folded plate of certain angle.Folded plate wave crest installs title " with setback plate ", wave crest phase to trough in parallel
Claim " different setback plate " to installation.Folded plate flocculator installation and maintenance are difficult, and folded plate is costly.
Mechanical flocculation basin refers to making aqueous agitation to complete the structures of flocculation process, such as with movable vane piece by machinery
Shown in Fig. 3, blender has pulpboard formula and vane type, divides horizontal axial type and perpendicular axis type machinery to wad a quilt with cotton by the installation site of agitating shaft
Solidifying pond.First lattice stirring intensity of mechanical flocculation basin is maximum, then gradually reduces, stirring intensity is decided by agitator speed and paddle
Plate suqare.Likewise, mechanical flocculation basin is also to have the deficiencies of maintenance difficult, maintenance cost is high.
Grid flocculation pool of grid strip is designed to the structure of more lattice vertical shaft reverse-flow types, as shown in figure 4, the installation of each vertical shaft is several
Layer grid or grizzly bar, the partition wall between each vertical shaft interlock aperture above and below, and water inlet end to water outlet gradually decreases, general point of 3 sections of controls
System, leading portion are close net or close grid, and middle section is that thin net or thin grid, latter end do not install net, grid.In contrast, grid flocculation pool of grid strip
Structure it is increasingly complex, installation, difficult in maintenance, and expense is also higher.
The structure design of rotational flow flocculation tank is, as shown in figure 5, peripheral jet water flow of the nozzle of water sprayer along pond, forms
The intensity of eddy flow, eddy flow is related with the volume of flocculation basin and shape by water sprayer spout flow control, while also.Rotational flow flocculation tank
Be limited to the injection intensity of water sprayer, volume is smaller, also, rotational flow flocculation tank is in addition to exclusive use, usually also with it is other
The flocculation basin or sedimentation basin of structure are used cooperatively, such as are built jointly in vertical-flow sedimentation basin, and the residence time is generally 8~
15min is suitable for middle-size and small-size water factory.
Perforation rotational flow flocculation tank, as shown in fig. 6, it is made of several grids, number of squares is no less than six lattice.Partition wall is opened up and down
Hole, water flow enter to form eddy flow along pool wall tangent line.First checkerwork cell mouth is small, and rotation speed is big, then successively successively decreases, corresponding rotation speed
Degree successively decreases.The perforation maximum deficiency of rotational flow flocculation tank is that there are terminal reseavoir bottom deposition phenomenons, also, algae is also easily bred on grid
Class, blocking mesh.
Precipitating is solid-liquid separation process, is that sewage acts on the suspension that density ratio water is big in sedimentation basin using gravitational settling
The processing structures that particle or coagulation product are removed from water are one of most widely used processing units in sewage treatment, can
The post-processing and advanced treating of processing, biological treatment for sewage.
Sedimentation basin includes five inhalant region, settling zone, buffer area, sludge area and exhalant region parts.Inhalant region and exhalant region
Effect be to flow through sedimentation basin with making uniform fluid flow, avoid it is short stream and reduction turbulent flow have an adverse effect to precipitating, reduce simultaneously
Dead water region improves the capacity utilization of sedimentation basin.Settling zone is also referred to as settling section, the i.e. workspace of sedimentation basin, can need to sink completely
The region that the particle in shallow lake is separated from water.Sludge area is the region of sludge storage, concentration and discharge.Buffer area is then to separate settling zone
With the water layer region in sludge area, guarantee that row does not float precipitated particle again due to water flow agitation.Sedimentation basin is to utilize water flow
The middle downward settling velocity of suspended impurity particle is greater than water flow cross-flow velocity, or the sedimentation time is less than water flow outflow precipitating downwards
The time in pond, so that suspended particulate contamination precipitation realizes the purification of sewage in bottom of pond.
Ideal sedimentation basin, treatment effeciency is only related with surface loading, i.e., related with the surface area of sedimentation basin, and with it is heavy
The depth in shallow lake pond is unrelated, pond it is deep only with time and quantity of sludge storage and to prevent sludge from the factors such as being washed away related.And
In the sedimentation basin of practical continuous operation, since water flow can bring the upflow velocity of water flow, precipitating weight from weir crest overflow is discharged
The particle that power is less than water flow upflow velocity power can flow away with water, and precipitate gravity and be equal to the particle of water flow upflow velocity power then
It can be still suspended in pond, the particle that only precipitating gravity is greater than water flow upflow velocity power just can precipitate in pond.And
Precipitating particle be deposited in sedimentation basin bottom of pond time it is related in the hydraulic detention time of sedimentation basin with water flow, i.e., with pond body
Depth is related.Therefore, theoretically, pond body is more shallow, and particle is more accessible to bottom of pond, this is exactly that inclined tube or inclined-plate clarifying basin etc. are shallow
Where the theoretical foundation of layer sedimentation basin.In order to make the particle precipitating in sedimentation basin slightly larger than upflow velocity go down and prevent from having precipitated
The sludge to go down by water inlet water flow disturbance and float again, thus there are bufferings between settling zone and sludge storage area
Area makes after contacting with each other between the particle for being slightly larger than upflow velocity in these sedimentation basins or the particle floated again, precipitates again
Go down.
Therefore, sedimentation basin is often divided into rectangular sedimentation tank, vertical sedimentation basin, radical sedimentation basin by water (flow) direction
With inclined tube or four kinds of inclined-plate clarifying basin.
Rectangular sedimentation tank, as shown in fig. 7, pond type is rectangle, sewage flows through pond from one end person who lives in exile in pond, horizontal direction
Son is flowed out from the other end in pond.Storage bucket is set in the entrance bottom in pond, other position bottom of pond have the gradient, tendency storage bucket.
Vertical sedimentation basin, pond type are mostly circle, are also square or polygonal, side view is as shown in figure 8, sewage
Enter from the central tube for being located at pond center, is uniformly slowly distributed in the cross section in pond after reflecting plate from the lower end of central tube
On, since water outlet is arranged in pond face or bay wall surrounding, substantially from bottom to top, sludge stores up the sludge in bottom to the flow direction of Gu Shui
Bucket.
Radical sedimentation basin, also known as radiation type precipitation pool, as shown in figure 9, how rounded pond type is, small-sized pond is also adopted sometimes
With square or polygonal.The import and export arrangement in pond is substantially identical as vertical flow basin, and import exports around in center.But pond
The ratio between diameter and Chi Shen, radial flow tank manyfold bigger than vertical flow basin.Water flow spoke stream or jet stream around in horizontal direction in pond, due to
Discharge section area constantly becomes larger, therefore the water velocity in pond slows down gradually from pond center to pond surrounding.Bucket is located at pond center,
Bottom of pond to center tilt, sludge usually with scrape mud or suction dredge tool exclusion.
Inclined tube or inclined-plate clarifying basin are as shown in Figure 10 the sedimentation basins that inclined tube is equipped in settling zone, and assembling form has tiltedly
It manages and two kinds of branch pipe.Inclined parallel pipe or parallelpiped are utilized in the settling zone of flat flow or vertical sedimentation basin, sometimes
Using honeycomb filler, a series of shallow layer precipitating layers are divided into, processed and sedimentation heavy mud is mutual in each precipitating shallow-layer
It moves and separates.It is divided into reverse flow, concurrent and three kinds of lateral flow different separate modes according to its mutual direction of motion.Every two pieces

Sheet, maintenance cost, operation energy consumption cost etc. are relatively high.In addition, because sedimentation basin carries out solid-liquid point using gravitational settling
From being influenced by sinking speed, the sewage treatment time is long, and anti impulsion load ability is poor.
Generally speaking, in existing technology, the volume of coagulative precipitation tank is big, takes up an area more, long construction period；Required equipment
Mostly nonstandard production, the technical difficulty for making requirement is big, and cost of investment is too high；Equipment arrangement scene is to site requirements height；Operation
Management requires and operating cost is all higher；When in face of pollution variety, adaptibility to response is poor.So many enterprises are mating this kind of at present
Identical problem is all suffered from when environmental protection facility, i.e. equipment purchasing is expensive, and equipment placement is difficult, and equipment operation maintenance is difficult, and equipment operation is expensive.
Therefore, it needs to improve facility used by existing coagulation-settlement process, to further reduce the cost, from
And sewage purification environmental protection facility is enable preferably to promote and apply.
