Description

Mud-water separation is with inclined tube and clarification/settler

Technical field

Utility model is to water treatment technology clarification, the precipitation improvement that separates inclined tube and clarification/settler, it is bigger to relate in particular to a kind of waterpower surface loading, separative efficiency is higher, the better mud-water separation inclined tube of separating effect, and as the main clarification/settler that constitutes.

Background technology

Give the clarification of water treatment, middle water Treatment for Reuse etc., perhaps water treatment deposition, its effect be make contain in the water tiny suspended particulate as early as possible, effectively sink to realizing with moisture from, particle quickens sedimentation separation to prior art in the big flood in order to add, improve the density of hydraulic surface loading and mud granule, more employing is filled in clarification or sedimentation basin and is separated swash plate or inclined tube, forms incorgruous stream mud-water separation clarification or precipitation.To so far, the effective means for the tiny suspended particulate of most economical effective acceleration in the water treatment sinks to separating is widely applied in water treatment with swash plate or inclined tube in separation, we can say almost and is not using in the neither one engineering of water treatment.Though it is present best silt particle, suspension and water separation device, objectively be not absolutely perfect, also have some deficiency: for example concurrent is because of forcing water distribution, and technical difficulty is big, and it is inhomogeneous to catchment, and now is eliminated; The incorgruous flow point of widely being used from, current rising flow direction is opposite with suspended particulate sinking traffic direction, suspended particulate (alumen ustum) infall process must be subjected to ascending current impact interference and cause pulsation like this, and influence sinks to separating and subsidence velocity, influences mud-water separation.For guaranteeing that good precipitate and separate efficient and effect are arranged, usually can only strengthen clarification or desilting area, make processing water be in ideal as far as possible and help the laminar condition that suspended particulate sinks, make that like this treatment pond floor space is bigger, with common water treatment technology, clarification or sedimentation basin area account for about 30-40% of whole engineering, and floor space is arranged in first or second in water treatment technology.Even big clarification or desilting area are set, still there are some small suspension flcos to can not get clarification/precipitate and separate, it is thorough inadequately to cause clarification or precipitation to remove turbidity, effluent quality is undesirable, be difficult to reach high water outlet water quality requirement, this also is a particularly major reason exceeding standard of sewage disposal water outlet SS of present water treatment, needing to demand urgently solving.Secondly, existingly being tilting swash plate or inclined tube, having only unidirectional shallow-layer separating power, also is to cause hydraulic surface loading little, another reason that the treatment pond floor space is big, and resistance to overload shock not, and effluent quality is subject to amount of inlet water, variation water quality influence.Besides, existing swash plate or inclined tube function singleness only have only the precipitate and separate effect, remove this and do not have other functions again in water treatment.

Adopt lateral flow (also claiming cross-current) precipitation though prior art discloses,, reduce interference, for example the sinking suspension so that current are vertical mutually with the separating solids flow direction.

Chinese patent CN86200155 combined lateral flow inclined plate sedimentation device, swash plate are erect median septum by multilayer herringbone swash plate, and side partition and structure set square constitute.This swash plate uses swash plate roughly the same usually, just changed swash plate channel direction and water (flow) direction, made current and suspension sink to being approximate vertical, to reduce the interference effect of current the sinking suspension, it still is unidirectional sedimentation separation, and uniquely has only the sedimentation separation function.So except that suspension settling of floccus and current interference, all the other existing swash plate deficiencies still exist.

Chinese patent CN2865823 air supporting and precipitation filling device adopt and to form swash plate by the alternate several layers thin plate that is parallel to each other, and make current be that lateral flow realizes by swash plate that suspension sinks and moisture from.Its purpose is the improvement of swash plate combining structure only, and to principle and not essence change of structure, except that suspension settling of floccus and current interference, all the other existing swash plate deficiencies still exist equally.

In addition, people have also taked following mode, for example for improving the sedimentation separation effluent quality.

Chinese patent CN101863546A multistage inclined tube or inclined-plate clarifying basin improve that mainly alternate multi stage precipitation wall or lateral flow inclined plate group being set in sedimentation basin.Do not change but just separate swash plate, so existing swash plate deficiency still exists; Secondly, adopt common swash plate to make alternate multistage lateral flow inclined plate group, make current pass through every lattice swash plate, all need change the direction of a stream of water, objectively strengthened resistance to water-flow, it is little to cause water flow to reduce.

Chinese patent CN101869781A improves and the stabilizing effluent quality of sedimentation tank method and apparatus, near the water outlet water leg sedimentation wall or lateral flow inclined plate group or different orientation flowing oblique tube or swash plate group is being set.Though, may improve effluent quality by do not hold increase by one or several groups of swash plates in water outlet, to separate swash plate and remain the common swash plate of prior art, its deficiency is objective reality still.

In the existing water treatment clarification/depositing technology, for helping clarifying fast and make fine suspension obtain sedimentation separation, before clarification/precipitation, adopt machinery flocculation and waterpower flocculation usually, make processing water be turbulent condition, quicken the fine suspension collision and increase wadding, help subsequent sedimentation and separate.Machinery flocculation and/or waterpower flocculation all need consumption of power, and the tourbillion flocculation that strenuous exercise produces is inhomogeneous, and it is of poor quality to form the silt flco, influences flocculating effect.

Above-mentioned prior art shows: though mud-water separation swash plate or inclined tube, and clarification or precipitation, invention has last 100 years history, and people also update it, but swash plate or inclined tube function singleness, unique have only unidirectional sedimentation function, and objective mud-water separation efficient and the effect of causing still is not best; Machinery flocculation and waterpower flocculation need consumption of power, and it is inhomogeneous that strenuous exercise produces the flocculation of water whirlpool, influences flocculating effect.Above-mentioned basic shortcoming is still effectively solved, and therefore still having is worth improved place.

The utility model content

The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of surface loading bigger, the better mud-water separation inclined tube of separating effect.

Another purpose of utility model is to provide a kind of application above-mentioned inclined tube, and realizes unpowered substantially flocculation, clarification/settler that flocculating effect is more excellent.

Utility model first purpose realizes, the main improvement is that the involutory ripple plate of forming inclined tube is separated, tilting divider is set in that separated space is alternate up and down, intake-outlet is arranged on the inclined tube sidepiece, with the parallel or almost parallel of alternate tilting divider up and down, thereby be formed with two-way shallow-layer centrifugation and cross the inclined tube that the fluid space contraction/distension cycle changes, thereby overcome the deficiencies in the prior art, realize the utility model purpose.Specifically, utility model mud-water separation inclined tube comprises by relative ripple plate and forming side by side, it is characterized in that side by side the ripple plate is over against alternate adjacent air space setting relatively, there is alternate separation swash plate bar up and down in the adjacent air space space, inclined tube intake-outlet and the parallel or almost parallel of separation swash plate bar.

Before the detailed description, make a presentation by the basic function and the effect that can reach earlier, so that those skilled in the art have one clearly to understand to this patent general plotting technical scheme invention.

Utility model is separated the involutory ripple plate of former composition inclined tube, and set up alternate swash plate bar up and down separating the ripple board space, and make and handle water from the turnover of inclined tube side (with the parallel or almost parallel of alternate swash plate bar up and down), thereby make the separation inclined tube have two-way shallow-layer separation function, promptly keeping on the former vertical shallow-layer separation basis, increase the horizontal shallow-layer of separation up and down, realized two-way mud-water separation.Two-way shallow-layer separates has not only increased separating area, thereby makes under the identical flow conditions of maintenance, has increased hydraulic load (can increase treating capacity or reduce separating area); Secondly, the same traffic that also makes two-way shallow-layer has reduced handles up-flow speed waterborne, also accelerated suspended particulate sink with moisture from, and lateral flow is separated, the water movement direction does not produce any interference to the sedimented particle of downward motion, thereby has improved clarification or precipitate and separate efficient and effect; Besides, the ripple plate is over against (forming the hexagon cellular inclined tube together relatively, trough, crest is not staggered relatively respectively), make that forming space, inclined tube cross section is the contraction/distension cyclically-varying, the contraction/distension cyclically-varying of overflow section, make and separate the little flocculating effect of water generates, make small suspended particulate in the sinking separation process, again obtaining flocculation in sinking to separating increases, become bulky grain and obtain separation, in precipitate and separate, increased the contact precipitate and separate function that little flocculation forms, made that the small suspension that can not separate sinking has originally obtained separating to sink, thereby improved effluent quality.Above-mentioned three aspect advantages, replace prior art inclined tube or the incorgruous flow point of swash plate from, have better technique effect, make it to have higher surface loading, higher separative efficiency and better separating effect.Has little flocculate and clarify/sedimentation effect.

In the utility model.

The ripple plate is used the hexagon cellular inclined tube over against alternate adjacent air space setting over against separating similar in appearance to the composition water treatment relatively, and is relatively staggered opposed for trough, the crest difference of ripple plate, makes the inclined tube cross section of making up be periodically contraction/distension variation like this; Alternate adjacent air space is different from and forms inclined tube continuously every involutory, but the alternate certain intervals that leaves, and reserves to be mainly used at interval to be provided with to form another and separate swash plate to shallow-layer, thereby constitutes the inclined tube that utility model has two-way shallow-layer centrifugation.Ripple plate phase spacing (minimum spacing between trough) is preferably 25-35mm; Alternate swash plate bar up and down between alternate ripple plate, spacing better also be 25-35mm, repetitive wave spacing 150-250mm, the inclined tube of empty size composition is around here tested and is shown to have appropriate relatively separating table area, mud-water separation best results.

The ripple plate of forming inclined tube can similar prior art make up inclined-tube wave plate, and a kind of being preferably adopted trapezoid ripple plate.Said ripple plate can be the regular wave plate that wide waveform repeats, and also can be the irregular wave plate that not wide waveform repeats, and wherein the trapezoidal rule ripple plate that repeats with wide waveform especially is excellent.Ripple Lamb wave height is preferably 3-6mm, and the too high meeting of wave height causes the lateral flow resistance to increase, and this is undesirable.For guaranteeing the unobstructed smooth whereabouts of up and down alternate inclined clapboard precipitation silt particle energy, a kind of better is for low ripple plate, alternate swash plate bar lower side up and down between alternate ripple plate is processed into and is sawtooth waveforms or square wave sawtooth waveforms, its medium wave indent is 6-10mm comparatively, wave spacing better equates with ripple plate repetitive wave spacing, 150-250mm for example, lower side has the indent side wave can increase the slip open area.Ripple plate gradient reaches phase swash plate bar gradient up and down, and same prior art for obtaining best mud-water separation effect, is preferably 60 degree.

Alternate swash plate bar is provided with fixing about between alternate ripple plate, a kind of better mode is for having the line of rabbet joint on the relative trough of alternate ripple plate, pass through laterally inserted in back, alternate ripple plate location, make swash plate bar two axial checkposts go into the line of rabbet joint and be fixed, certainly the technical staff thinks and adopts that other modes are fixing also to be fine.

Utility model second purpose realizes that main the improvement is that clarification/settling zone adopts aforementioned separation inclined tube, and makes the processing water and the parallel or almost parallel of the horizontal alternate separation swash plate bar of utility model inclined tube that passes through inclined tube in the treatment pond at least.Specifically, utility model clarification/settler comprises treatment pond and built-in device for separating mud and water, it is characterized in that device for separating mud and water be side by side relatively the ripple plate over against alternate adjacent air space setting, the inclined tube that the adjacent air space space is made up of alternate separation swash plate bar up and down; At least make the processing water and the parallel or almost parallel of the horizontal alternate separation swash plate bar of inclined tube that pass through inclined tube in the treatment pond.

In addition, sink to clarifying or precipitation for helping carefully lacking suspension, can before clarification/settler, add turbulent flocculation reaction with prior art, to be formed with the flco that is beneficial to sedimentation, for saving turbulent flocculation reaction operation energy consumption, and raising flocculating effect, a kind of preceding turbulent flow of clarification/precipitation that is preferably flocculates, adopt grid by the alternate setting of flow direction, current produce flow-disturbing by alternate grid and grid rib and form the whirlpool flocculation reaction, so successively by alternate grid, produce velocity gradient, make current become turbulent condition, reach unpowered substantially turbulent flow flocculation function, and whirlpool flocculation reaction, the whirlpool that forms is little, evenly, dense, velocity gradient is big, make water body be in stable turbulent condition, the silt floc particle size that forms evenly, density is big, increased substantially flocculating effect, having overcome the flocculation of prior art turbulent flow must additionally increase power (machinery flocculation and/or waterpower flocculation), and the water whirlpool flocculation that strenuous exercise produces is inhomogeneous, it is of poor quality to form the silt flco, influences the deficiency of flocculating effect.

In the utility model.

At least make the processing water and the parallel or almost parallel of the horizontal alternate separation swash plate bar of inclined tube that pass through inclined tube in the treatment pond, can there be two kinds of modes to realize, the one, making clarification/settler is lateral flow Inlet and outlet water (prior art is last dirty), the 2nd, place the inclined tube both sides at clarification/sedimentation basin, respectively be provided with vertical dividing plate, Inlet and outlet water stops that by dividing plate changing cross-current into crosses inclined tube about making clarification/sedimentation basin, and the selection of two kinds of modes is looked concrete clarification/sedimentation basin layout and selected.

Grid by the alternate setting of flow direction, its effect is current to be flow through can form the flocculation of generation turbulent flow, thereby replace turbulent flow flocculation of prior art machinery and the flocculation of waterpower turbulent flow, the turbulent flocculating effect of the voluminous more life of obvious alternate grid is good more, therefore, a kind of better is with the processing pond, and adjacent separation is divided into a plurality of insulating spaces that are communicated with up and down, it is mobile that processing water is turned back between each separating adjacent pond, to strengthen turbulent flocculating effect.

Grid, effect are to make water pass through alternate grid and the formation of grid rib bumpy flow, the particularly bumpy flow that forms around rib, thereby the disturbance current play the flocculation reaction effect.Test is compared, and a kind of more preferably each grid adopts circular rib, and such as but not limited to rope, reinforcing bar, roller rod etc., the grid circular rib not only has the less flow resistance of crossing, and produces the flow-disturbing better effects if, helps forming better eddy-currents flocculation.Grid can be the rope weave mesh, perhaps plastic grid, and perhaps metal grill or the like does not have unique appointment to material and form.Grid configuration does not have yet and must limit, and can be rectangle, square or other geometries.The grid of alternate setting up and down, better be increasing gradually on the distance theory with handling water (flow) direction, because prolong along with handling the current journey, the flocculation particle increases gradually, flocculating strength should weaken gradually, can not make flco fragmentation in strong disturbance of having flocculated that flco is reduced like this, but can increase manufacture difficulty like this, therefore, another kind of mode can adopt with the pond mesh spacing and equate, mesh spacing strengthens mode with water (flow) direction in the adjacent pool, promptly the interior grid interval of second treatment pond (or unit) is greater than the interior grid interval of first treatment pond (or unit), the interior grid interval of the 3rd treatment pond (or unit) is greater than the interior grid interval of second treatment pond (or unit), by that analogy.Test shows: the utility model grid hole, better adopt 50-60 * 50-60mm square, and it is better relatively to produce vortex stream effect; Grid floor height 10-15mm, spacing 80-150mm between clathrum, this cooperates the heavy vortex stream of generation effect will get well relatively.

The technical staff should be understood that and understand, and aforementioned condition obviously can not be interpreted as the necessary condition that realizes the utility model basic effect, and just utility model is tested a kind of preferable interval, departs from this interval value and just do not represent and can not realize the utility model basic function.

Utility model mud-water separation inclined tube, and the water treatment clarification/settler that constitutes thus, with respect to prior art, because inclined tube adopts said structure, make that forming the utility model inclined tube has two-way shallow-layer separation function, formed shallow pool area is far longer than the formed shallow pool area of unidirectional sedimentation inclined tube, and motion does not exert an influence current to sand grain in motion process, Separation of Solid and Liquid is taken their own roads, and silt particle, the downward sedimentation state of flco are with respect to the precipitation state in hydrostatic; Particularly inclined tube has according to the water (flow) direction cross section and periodically shrinks/enlarge, current are the variable cross-section curve and flow in inclined tube, make and to contact little flocculation reaction in the suspension sinking mud-water separation process, carrying out little flocculation and infall process simultaneously, overcome the defective of widespread usage different orientation flowing oblique tube, replace prior art swash plate or the incorgruous stream mud-water separation of inclined tube, has better technique effect, make it to have higher surface loading and (can save occupation of land, reduce investment, perhaps improve disposal ability), higher mud-water separation efficient and better mud-water separation effect, the small suspension that can make some can not sink to separating originally can access effective separation, make that the separation effluent quality is more excellent, turbidity removal is thorough, and capacity of resisting impact load is improved, and handles more stable.Clarification/settler as core, under identical effluent quality situation, can allow higher water inlet suspension content, obviously improved deposition efficiency, compare and to raise the efficiency more than 30% with tradition clarification/settler, and can obviously improve clarification, precipitated outlet water water quality.Before clarification/settler, adopt the flocculation of grid turbulent flow, current are by alternate grid, constantly produce more whirlpool composite flocculation reactions, have the waterpower flocculation reaction concurrently and contact little flocculation reaction function (composite flocculation reaction), the whirlpool of formation is little, even, dense, velocity gradient is big, make water body be in stable turbulent condition, the silt floc particle size that forms is even, and density is big, has increased substantially flocculating effect, mud-water separation is effective, can improve clarification/precipitated outlet water water quality.Secondly, flocculation reaction intensity is effective greatly, and hydraulic detention time is short, and the more conventional depositing reservoir of waterpower surface loading (as high dense settling pond) increases more than 1/3, and the flocculation reaction surface area can reduce more than 1/3, and identical tanks is held can make the processing load be improved.Besides, under Inlet and outlet water flows, just can finish turbulent flocculation reaction, can accomplish not increase substantially turbulent disturbance consumption of power, realize unpowered substantially flocculation (mechanical disturbance flocculation and hydraulic disturbance flocculation relatively).The utility model mud-water separation can be used for various clarifications of giving water treatment, water Treatment for Reuse with inclined tube and clarification/settler, and the sewage disposal precipitation.
