[background technology]
Horizontal sedimentation tank be a kind of bottom surface be rectangular armored concrete or brickwork construction, in order to carry out the pond of precipitation process.Shortcoming be dark big because of the pond, the time of staying long, flow turbulence and density current disturb greatly, causes the sedimentation effect instability, surface loading is low.
For overcoming the deficiency of horizontal sedimentation tank, a kind of many lattice of multilayer sedimentation basin has appearred in eighties of last century the fifties.Horizontal sedimentation tank is separated into after the many lattice of multilayer, and every layer pond shoals deeply, and the time of wadding grain precipitate and separate shortens, and horizontal flow velocity can increase; Because the separation of the many lattice of multilayer has reduced the cross-section of river of single lattice, has increased wetted perimeter, thereby has reduced Reynolds number, has increased Froude number, reduced the interference of turbulent flow with density current, improved sedimentation effect and stability, improved the surface loading of sedimentation basin greatly.The west of a river, Changsha water factory has obtained good effect in engineering practice, but insoluble be the spoil disposal problem of sedimentation basin.The way that adopted at that time is to establish a perforated sludge discharge pipe canal in the bottom, shallow pond of every layer of every lattice, and every layer spoil disposal pipe duct compiles back sidewall discharge from the pond.Because sludge discharge effects is undesirable, and the application of failing to put it over.
Having the people to propose a solution for many years is that many lattice of multilayer sedimentation basin is tilted, utilize gravity make mud at the bottom of the pond that tilts landing to bucket, for the length that reduces the settling zone distance of interlayer is compressed to very little, thereby developed inclined-plate clarifying basin.
Afterwards again the someone to propose another kind of solution be that laminar flow developmental tube and many lattice of multilayer principle are combined; Utilize the current that are in laminar condition in the tubule to get rid of the interference of turbulent flow fully with density current; Created desirable deposition condition; And the spoil disposal mechanism of using swash plate, thereby developed the inclined tube filler, and tube settler and settling vessel.Will be to the surface loading of sedimentation basin in the water treatment 1～2m by horizontal sedimentation tank
3/ (hm
2) bring up to 5～9m
3/ (hm
2), see GBJ13-1997, GB5013-2006 Code for design of outdoor water supply engineering for details.The new stage that makes sedimentation and equipment develop into a higher level, and obtained to use widely in sewage disposal and other industries.Yet with swash plate, tube settling is that one type of technology of representative itself exists following deficiency:
All be in the same runner because water (flow) direction becomes adverse current or cross-flow with mud landing direction, cause the phase mutual interference.Must the restriction water velocity less than mud landing speed, otherwise just can cause can't spoil disposal and heavy mud dashed also quilt by current and taken out of, this is the main cause that surface loading can not improve again.
No matter be inclined tube or inclined-plate clarifying basin, the pond is deeply very big, but effectively settling zone height proportion is very little, in the settling zone one deck can only be set, and can not multilayer superpose, and this is another major reason that surface loading can not increase substantially.
Because they become a mandarin, effluent all in vertical direction, and are inconsistent with the bottom horizontal flow sheet direction, make the sedimentation basin complex structure, particularly to set up complicated filler support system and go out water collection system.
For large-scale sedimentation basin, because the settling zone exists filler and filler support system and goes out water collection system, bring difficulty for the bottom spoil disposal, particularly make mechanical dredge equipment and pond structure complicated, increased the difficulty of capital expenditure and maintenance.
