Specific embodiment：
As shown in Figure 1 and Figure 2, including circular cylinder body 1, circular cone bucket 2, support 3, tubaeform guide shell 4, circular radome fairing
5th, reflection cone 6, circular water outlet weir plate 7, water inlet 8, medicament mouth 9, delivery port 10, sludge mouth 11.By circular cylinder body 1, circular cone
Bucket 2, tubaeform guide shell 4, circular radome fairing 5, circular water outlet weir plate 7 form mixed zone, reaction zone, Sludge Bed filtering area, clear
4, pool etc. functional areas.
Sewage and a small amount of medicament (such as flocculant, demulsifier, weighting agent) enter after sludge bed filter and a small amount of backflow is dirty
Mud is mixed, and effectively decontaminated water is removed behind mixed zone, reaction zone, Sludge Bed filtering area, clear water zone under unpowered service condition
In suspension, colloidal solid thing, oil slick, oil emulsion, polluter, the clear water such as turbidity periodically arrange from outflow filter, sludge
Put.
The sludge isolated is precipitated from sewage and forms the suspended sludge with good adsorption properties in Sludge Bed filtering area
Layer, suspended sludge layer adsorb the polluters such as the suspension intercepted in sewage, colloidal solid thing, oil slick, oil emulsion, turbidity.
Sewage is 30-40m/h in the flow velocity of reaction zone, and up-flow speed of the sewage in Sludge Bed filter zone is 1.5-
3.0m/h.Hydraulic detention time of the sewage in mixed zone, reaction zone, Sludge Bed filtering area, clear water zone is respectively 5-8min, 8-
15min、40-60min、25-40min。
According to different quality condition, medicament is by selective flocculant, demulsifier, weighting agent or its various combination, it is ensured that water outlet
Water quality reaches requirement.This unpowered sludge bed filter is particularly suitable for handling containing high concentration suspended matter, petroleum-type, turbidity
Sewage.
The application method and principle of specific embodiment：
As shown in Fig. 2 sewage from water inlet (8) and a small amount of medicament from and medicament mouth (9) is with pressure enters filter, mixing
Turbulent stirring action is formed under the hydraulic blow of turning back of area's reflection cone (6) and is mixed on a small quantity from the inoculation of circular cone bucket (2) backflow
Sludge, sewage, medicament and seed sludge are sufficiently mixed in mixed zone and form homogeneous mixed liquor.
In mixed zone, a small amount of sludge of backflow plays " inoculation " effect in sewage, and the mud granule of inoculation plays wadding
Solidifying reaction, the nuclei of crystallization effect of demulsification reaction, colloidal solid thing is accelerated to be condensed into suspension, oil emulsion particle aggregation into oil slick
Drop.
Mixed liquor is upwardly into reaction zone along tubaeform guide shell (4), reach turn back behind circular radome fairing (5) top to
Under, until the tubaeform diffusing opening in bottom of circular radome fairing (5).Sewage, medicament and sludge fully carry out flocculating instead in reaction zone
, should be demulsified reaction, adsorption reaction：Trickle colloidal solid thing and trickle turbidity material in sewage " compress double electricity in flocculant
The suspension of mutual coacervating large particle under layer " and " net is caught " effect；Trickle emulsification oil particles in sewage are in the " broken of demulsifier
The oil slick drop of mutual coacervating large particle under interfacial film " and " coalescence " effect；Oil slick drop and proportion regulating agent knot in sewage
Close and form heavy oil drop of the proportion slightly larger than 1；Bulky grain suspension, oil slick drop in sewage, heavy oil drop further adsorb trickle
Colloidal solid thing, emulsification oil particles, the turbidity material of grain.
Mixed liquor enters Sludge Bed mistake after reaction zone fully reacts from the tubaeform diffusing opening in bottom of circular radome fairing (5)
Area is filtered, passes through Sludge Bed filtering area at a slow speed from bottom to top.The suspension isolated is precipitated from sewage with oil droplet in Sludge Bed mistake
Filter area formed suspended sludge layer, suspended sludge layer with fine and close flocculation structure and containing flocculant, demulsifier and with well
Absorption property, suspended sludge layer absorption intercept suspension, heavy oil drop, oil slick drop, colloidal solid thing, oil emulsion in sewage
The polluters such as grain, turbidity, are purified sewage.
Clear water after purification flows upwardly through clear water zone, the wherein a small amount of suspension of further gravity settling separation in clear water zone
Thing.Last clear water excludes filter through circular water outlet weir plate (7), delivery port (10).
A small amount of suspension of clear water zone sedimentation separation is downwardly into suspended sludge bed.
The suspended sludge layer of Sludge Bed filtering area maintains dynamic equilibrium.On the one hand the suspension constantly isolated from sewage
Thing, oil droplet are added in suspended sludge layer, suspended sludge layer is constantly increased, and remain outstanding in the presence of sewage upflow velocity
Floating state；On the other hand, suspended sludge layer constantly increases fine and close, proportion increase, because Action of Gravity Field is constantly run to bottom, leads to
Cross circular cone bucket (2) and sludge mouth (11) periodically discharges a part of sludge.Visually observed in day-to-day operation by transparent window
The thickness of suspended sludge layer monitors sludge concentration to judge the thickness of suspended sludge layer by the sample tap of different parts.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by the protection domain of claims.
