Abstract
Provided is an oscillatory type sewage sedimentation basin, which utilizes a tilting system to tilt a movable basin, so as to generate gradient tangential deformation and resonance on raw water, promote a flocculation reaction and improve sewage treating effect, and an operation method thereof. The movable sedimentation basin is jointed with a pedestal hinge and can tilt around the hinge under a tilting operation of the tilting system. When sewage reaches a destabilization critical state, the tilting mechanism is started to tilt the movable basin to generate gradient tangential deformation on the raw water and promote the flocculation reaction. A basin tilting period is controlled to generate resonance oscillation on the raw water. The resonance promotes fully conduction of the flocculation reaction, so as to purify the raw water repeatedly, separate the settlement thoroughly and reduce suspensions. The settlement progress consumes a short time and energy, has good effect and low costs and is green, environment-friendly and easily operated.

The specific embodiment
In the embodiment shown in fig. 1, the center of gravity line of active pool body bottom is provided with hinge and is connected with fixed pedestal, the supporting hinge left and right sides, and two groups of hydraulic pressure tilting systems are symmetrically distributed, and their hydraulic stem is connected with pond body hinge respectively.
Former water leaves standstill the some time with pond body and former water level, to eliminate wave or the sinuous flow that produces when former water is gone into the pond after injecting.
When former water sinuous flow is eliminated, and the water-borne glue body reaches when taking off steady critical condition, starts the hydraulic pressure tilting system, and the left and right sides hydraulic stem replaces move toward one another, and is with certain speed that the pond body is moving to an inclination, reaches the set angle value of fascinating; With certain speed the pond body is oppositely fascinated immediately, the cycle of the pond body that fascinates is consistent with the natural period of oscillation of Chi Zhongyuanshui; Fascinate behind the pond body several times (number of times is no less than once), pond body level is left standstill.
Because the pond body fascinates, former water produces the tangential deformation of gradient with the motion of pond body, and the shear amount of each water layer is unequal in the same time, and the rate of deformation between water layer is also inequality, produces relative motion between water layer.
Suspension wadding nuclear between same water layer is with water sports, because the suffered hydraulic resistance of different scale particle is different, the particle between the different scale produces speed difference.Fireballing wadding nuclear is caught up with slow-footed wadding nuclear, comes in contact collision, is merged into bigger wadding grain.
Some small-sized wadding nuclears, their movement velocitys are the fastest, also do not touch the meeting that collides with large scale wadding stone grafting on the way, and they take the lead in moving near the pool wall.Hindered by pool wall boundary layer fluid viscous effects and pool wall shape, assemble near the border pool wall gradually, and the wadding cuclear density improves gradually, and spacing is more and more littler.Wadding nuclear is assembled, and density improves, and spacing is dwindled, and favourable wadding is internuclear sticks, crosslinked, and coalescence forms large scale, big quality, firm, closely knit big flocculating body and precipitates.
What arrive at last is large-sized wadding grain, and it has huge surface area, remaining gathering micelle net is caught, is rolled up and sweep the closely knit big flocculating body of formation, and precipitate.
There is speed difference in adjacent water layer, and the particle speed of a last water layer is fast, and they scanned aspect, is easy to catch the slow particle of movement velocity in the lower floor, is combined into big wadding grain.
The grain of no matter wadding a quilt with cotton is big or small, and speed under the acting in conjunction of water body shear action and gravity, is assembled to the motion of pond body two side lower parts by pool center gradually.Borderline region is to quicken the main region that deposition forms near the pool wall.
The deposition blocking zone, aerosol density is big, viscosity is big, the mutual interference effect of suspended particulate increases, particle in water, receive gravity, buoyancy and water resistance, the mutual interference drag of particle balanced action, subsidence velocity is very slow.
When the tangential deformation of water body causes the shear effect between water layer, tangentially relative motion between particle, balance structure factor changes, and the retardance balancing network is sheared destruction, causes caving in of the original balance constructive system of vertical.The upper strata downward ballistic motion of floc sedimentation of caving in, micelle is enlisted the services of in winding on the way, form bigger, more real flco.Cave in impact, the squeezing action of material are extruded the interface with interaction particle intermediate gap liquid, and solid particle group is concentrated.
Consistent when fascinate cycle of pond body of tilting system with the natural period of oscillation of Chi Zhongyuanshui; Former water resonates, even stop the pond body that fascinates immediately.But because the resonance effects of former water, water body circulates repeatedly still and vibrates the bump pool wall.The former water phugoid oscillation constantly that resonates produces the tangential deformation of gradient on left and right directions.Resonance water body wave amplitude is high, and distortion is big, and the mutual shear action between water layer is also bigger, more helps the carrying out of flocculation reaction.The resonance water body oscillatory extinction time is longer, the number of oscillation the more, flocculation reaction is just carried out more fully, just more thoroughly, suspended substance removal gets the more in flocculation reaction, water body is also just clean and clear.So oscillation action makes that former water is just purified repeatedly, suspension reduces greatly.
Constantly along the relative motion of the tangent plane left and right sides, block interim balance and constantly be sheared destruction between particle, the vertical constructive system constantly caves in, and solid particle group is also constantly assembled to be concentrated.
Pond bottom precipitation flco general size is big, more firm, closely knit.Reciprocating vibration causes the rate of flow of fluid that streams flco big, produces whirlpool in the flco both sides.Whirlpool has been assembled a large amount of wadding nuclear to the effect of entrainmenting of adjacent fluid in vortex core.The wadding cuclear density heightens, and has increased wadding nuclear in the contact of vortex core, crosslinked and coalescence, impels the fluid suspended thing in flco both sides constantly to deposit, and forms pond bed-sit line shape deposition.At the bottom of protruding grizzly bar structure or pond are set at the bottom of the pond, be wave structure, all can strengthen the whirlpool effect of streaming, accelerate sedimentation of suspension.
The storage bucket is arranged at the bottom of the pond, be provided with the gradient at the bottom of the pond along its length, tilt, be beneficial to sediment and compile to the slippage of storage bucket gradually to the storage bucket.
The floc sedimentation that sinks to the bottom under tangential hydraulic action, about swing repeatedly, the slip viscosity resistance of its underpart reduces greatly.In periodic swing, downslide component constantly drives flco downward sliding motion along the inclined-plane, is slipped to the storage bucket of surface bottom at last.
When dirt separated and be compressed in the pond at the bottom of, it is clean and clear that water body becomes, just can be through toppling over or opening apopore and emit clear water, mud enters sludge-tank, the pond body that soars just can carry out new Processing tasks.
