Description
Technical field
The present invention relates to a kind of fluid mixed reactor and water treatment facilities.
Background technology
At present, municipal middle water is progressively applied, but the secondary water treating pond efficient of traditional cities sewage treatment plant is lower, the requirement of water reuse during water outlet can't be satisfied, and main cause is that suspension, total phosphorus content exceed standard.Existing fluid mixed reactor comprises sedimentation basin, and volume is bigger, and fluid mixing, reaction, flocculation, spoil disposal need be than large space, and water inlet, stirring, spoil disposal all need consume big volume and electricity, and mixture homogeneity is relatively poor, reaction speed is slow.
Summary of the invention
The present invention will provide a kind of mode change sleeve flow velocity eddy flow combined reactor and efficient composite precipitation pond, solves fluid mixing, reaction, flocculation, spoil disposal speed slow, consume energy high, the relatively poor technical problem of mixture homogeneity, and the low problem of water treatment efficiency in solving.
The technical scheme of mode change sleeve flow velocity eddy flow combined reactor of the present invention: comprise urceolus and inner core, it is characterized in that: cylindrical urceolus is in the same place with taper inner core concentric locking collar; Wherein inner core is the up-thin-low-thick taper reducing inner core of barrel dliameter, and the lower end of reducing inner core is connected with the water outlet anemostat that stretches out urceolus, and the upper end of reducing inner core is immersed in the urceolus, and is equipped with the inner core agitator; The tangential of urceolus bottom is connected with water inlet and chemical feed pipe.
Above-mentioned water outlet anemostat is a toroidal.
Above-mentioned water inlet and chemical feed pipe are connected the eddy flow guide with junction, urceolus bottom, and this eddy flow guide is tangentially to the forward spin flow shape.
The technical scheme in the efficient composite precipitation of mode change sleeve flow velocity eddy flow of the present invention pond: effluent trough is arranged at the top at sedimentation basin, at the sedimentation basin middle part is settling section, be communicated with discharge pipeline in the sedimentation basin bottom, it is characterized in that: mode change sleeve flow velocity eddy flow combined reactor vertically is housed in the sedimentation basin, and this combined reactor is in the same place by cylindrical urceolus and taper inner core concentric locking collar; Wherein inner core is the up-thin-low-thick taper reducing inner core of barrel dliameter, the lower end of reducing inner core is connected with the water outlet anemostat that stretches out urceolus, the outlet of water outlet anemostat is positioned at the suspended sludge layer of sedimentation basin bottom, and the upper end of reducing inner core is immersed in the urceolus, and is equipped with the inner core agitator; The tangential of urceolus bottom is connected with water inlet and chemical feed pipe.
The settling section at above-mentioned sedimentation basin middle part is provided with inclined tube.
Be equipped with electronic mud valve on the above-mentioned discharge pipeline, the level meters in this valve and the sedimentation basin are electrically connected.
Beneficial effect: the present invention utilizes waterpower coagulating principle of dynamics, and current are managed intersection and are the eddy flow variable motion in outer tube and reducing, mixes with coagulant, mixing velocity is fast; Current mix with flocculant in the reducing inner core, and the stirring region volume is little, and the agitator power consumption is few, and floccule body is slow sinking with the expansion gradually of inner diameter of steel flue, finally discharges from the water outlet anemostat; Can make four flow processs of growth and degassing spoil disposal of in same sedimentation basin, finishing mixing, reaction, floccule body advance water, integrate mixing, reaction, flocculation and degassing spoil disposal function, improve the efficient of fluid purification greatly.Have mix, react completely, flocculation, the fireballing characteristics of spoil disposal, can be used for sewage, middle water purified treatment.
When processed current produce upwards unsteady flow speed rotary water current under the effect of urceolus eddy flow guide 6, the medicament that water inlet and chemical feed pipe 1 add further mixes and reaction at this.Because the design feature of reducing inner core makes that the flow velocity of water inlet when the urceolus eddy flow makes progress is slack-off gradually, this meets the principle of hybrid reaction.
Feed water flow falls into the import of reducing inner core when the top of urceolus 2, be provided with the inner core agitator at this, adds high polymer coagulant simultaneously herein.Under the drop and the acting in conjunction of agitator, intake with after high polymer coagulant fully mixes, from top to bottom the slack-off gradually water outlet anemostat 5 that enters of flow velocity.This process has been finished mixing, reaction, the growth of floccule body and four flow processs that outgas.
The lower end of reducing inner core 3 connects water outlet anemostat 5, send into the suspended sludge layer 16 of radical sedimentation basin 7 equably by its water inlet that will have little wadding particle, it makes little wadding particle by carrying out contact flocculation between the high big wadding grain group of the concentration that generated in the pond, thereby these little wadding grains promptly are adsorbed on the big wadding grain group, thereby have improved the speed of holding back and the heavy speed that has improved the wadding grain.
In order to guarantee contact flocculation effect preferably, must keep suspended sludge layer 16 that certain height is arranged, suspended sludge layer 16 can not influence the water outlet of settling section 15 again simultaneously, for realizing this purpose, is provided with body refuse level meters 13 in the pond.When slime layer reached certain height, level meters provided signal, controlled electronic mud valve 14 spoil disposals; When slime layer dropped to specified altitude assignment, electronic mud valve 14 was closed automatically.
In order to guarantee water outlet effect preferably, according to " shallow layer precipitating " theory, different orientation flowing oblique tube 12 is set, to shorten the sedimentation time, to increase surface loading at the settling section of sedimentation basin.Simultaneously, the biomembrane that generates on inclined tube also helps further to reduce the content of organics in the water outlet.
This invention utilize efficient composite precipitation pond that mode change sleeve flow velocity eddy flow combined reactor forms as in a important step---coagulating sedimentation in the water treatment technology, remove suspension in the water, total phosphorus etc.Other processing links of water in cooperating again, the water standard of water reuse in making it to reach.By the processing of water treatment facilities of the present invention, be that effluent SS can drop to below the 5mg/l under the secondary treatment yielding water condition of municipal sewage plant in water inlet; TP can drop to below the 1mg/l.
