Different folded plates, first paragraph is different setback plate, and second segment is same setback plate, and the 3rd section is parallel straight panel, contribute to flco into
It is long, hybrid reaction is tried one's best completely, and the broken of flco is not caused, while being provided with two kinds of vortex waddings of model in reative cell
Solidifying reactor, and the combination collocation in the vortex reaction time, vortex setting height and Vortex reactor in each reative cell is suitable
Sequence and its percent opening control are designed according to treatment raw water quality.The current of coagulant have been added to pass through folded plate and Vortex reactor
Afterwards, current form small vortex flow, are conducive to the diffusion of particulate in water, fluid energy are made full use of, while using folded plate
Flocculation is cooperateed with vortex, increase the collision probability for taking off steady micelle, form that flocculation better quality, density is high, separating property
Good solid-liquid two-phase system, and the efficiency of flocculation reaction is fundamentally improve, have significantly to improving water purification water and water quality
Effect.
Second, being provided with tube settler in clarified separation room, the precipitation to tiny particles content is enhanced, preferably protected
The sedimentation effect and clarifying efficiency of depositing reservoir are demonstrate,proved, with hydraulic surface loading higher.
Third, being additionally arranged sludge refluxing apparatus, partial sludge is back to raw water, is reprocessed after mixing with raw water, played
The effect of enhanced coagulation, while spoil disposal water gets utilization, not only improves treatment effeciency also saving water resource, reduces dirty
Mud is discharged and disposal amount.System flowback parameter controls the parameters such as different reflux ratios respectively according to raw water quality difference, such as table 1
It is shown.
Fourth, high pressure backwash water pipe is additionally provided with sludge drainage system, near periodic flushing and disturbance discharge pipeline and sludge bucket
Sludge blanket, prevent sludge discharge pipeline and bottom of pond alluvial it is hardened.
The application of the technology, it is possible to increase the flocculation reaction efficiency of water-purifying process, shortening flocculation time, reduction head are damaged
Lose, reduce medicine consumption, improve water purification water quality, and also improve the separative efficiency of precipitation, the yield of sludge is reduced, with higher
Society and economy effect.
The weak point such as flocculation and clean-up effect that the present invention can solve depositing reservoir generally existing are poor, energy consumption is higher.
A kind of vortex collaboration flocculation of folded plate and tube settling method for treating water that the present invention is provided are based on folded plate micro swirl co-coagulation
What technology, shallow pool theory basis and sludge reflux enhanced coagulation were proposed in theory.The technology is mainly assisted including folded plate micro swirl
Same reaction technology, tube settling isolation technics and sludge reflux enhanced coagulation technology.
Outstanding advantages of the invention：Can be in the case where most of structure of existing depositing reservoir be kept, to flocculation reaction
Unit carries out appropriate transformation, and auxiliary placing folded plate Vortex reactor wherein, the clean-up effect being obtained in that.For not
Same water quality, by controlling the percent opening of water velocity and Vortex reactor, while the parameters such as reflux ratio of returned sludge are adjusted,
And then obtain more preferable clean-up effect.
