The utility model content
The utility model proposes a kind of sewage treatment equipment of sticking with paste resin technique, solved the defect that sewage treatment equipment of the prior art can not be applicable to the waste water of high COD and SS content.
The technical solution of the utility model is achieved in that a kind of sewage treatment equipment of sticking with paste resin technique, it is characterized in that comprising: mother liquor pond, slurry sediment pool, dense slag bath and the pressure filter more than two, wherein, in described mother liquor pond, be provided with a mother liquor pump, the output channel of described mother liquor pump is connected to described slurry sediment pool, the bottom of described slurry sediment pool is provided with discharge opening, this discharge opening is connected to described dense slag bath, in described dense slag bath, be provided with dense pulp pump, the output channel of described dense pulp pump is connected to described pressure filter.
Further, the opening for feed of described slurry sediment pool is provided with a line mixer, and the output channel of described mother liquor pump is connected to described line mixer.
Further, described sewage treatment equipment also comprises grug feeding jar, in described grug feeding jar, is provided with a dosing pump, and the output channel of described dosing pump is connected to described line mixer.
Further, described dense pulp pump forms by the first dense pulp pump be used to exporting clear liquid be used to the second dense pulp pump of exporting underflow, and the described first dense pulp pump and the second dense pulp pump are connected to respectively two described pressure filter.
Implement the sewage treatment equipment of this paste resin technique of the present utility model, have following beneficial effect: this sewage treatment equipment can be realized sticking with paste the sharp separation of resin processing wastewater and process, and the environmental pollution that has reduced, realized waste recycling.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the sewage treatment equipment of paste resin technique of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all belong to the scope of the utility model protection.
Sewage treatment equipment with reference to of the present utility model this paste resin technique shown in Figure 1 comprises: mother liquor pond 1, slurry sediment pool 2, dense slag bath 3, pressure filter 4, grug feeding jar 6 more than two.
Wherein, in described mother liquor pond 1, be provided with a mother liquor pump 101, the output channel of described mother liquor pump 101 is connected to described slurry sediment pool 2.Slurry sediment pool 2 has the opening for feed that is positioned at top and is positioned at the discharge opening 201 of bottom.This opening for feed is provided with a line mixer 5, and the output channel of described mother liquor pump 101 is connected to described line mixer 5.The additive that described line mixer 5 provides for fully mixing the interior mother liquor in mother liquor pond 1 and grug feeding jar 6.Discharge opening 201 is connected to dense slag bath 3.
In described dense slag bath 3, be provided with dense pulp pump 301, the output channel of described dense pulp pump 301 is connected to described pressure filter 4.Described dense pulp pump 301 forms by the first dense pulp pump be used to exporting clear liquid be used to the second dense pulp pump of exporting underflow, and the described first dense pulp pump and the second dense pulp pump are connected to respectively two described pressure filter 4.By the press filtration of pressure filter 4, mother liquor is separated into clear liquid and filter cake the most at last.The first dense pulp pump can be positioned at the top of dense slag bath 3, in order to fully receive the top layer clear liquid.The second deckered stock chest can be positioned at the bottom of dense slag bath 3, and it can pour into solid sediment pressure filter 4.
In grug feeding jar 6, be provided with a dosing pump 601, the output channel of described dosing pump 601 is connected to described line mixer 5.In the utility model, can determine according to the composition of mother liquor composition and the content of the additive of grug feeding jar 6 can comprise soda acid, flocculation agent etc.Because these compositions have been that prior art is disclosed, the utility model is not done and is repeated.
This sewage treatment equipment of the present utility model to polymerization process after the waste water of cleaning equipment carried out the comprehensive regulation and utilization, it is divided into to clear liquid discharging to sewage works (meeting qualified discharge) and sticks with paste a resin blob of slag and reclaim (as the inferior grade product, selling), not only solve the up to standard of his SS of the COD in the discharge of wastewater, and used the part resin in resin wastewater to be recycled.Waste water after cleaning is delivered to 2 li of slurry sediment pools by mother liquor pump 101, and the underflow in slurry sediment pool 2 is delivered to 4 li, pressure filter by dense pulp pump 301 and carried out press filtration, resolves into clear liquid (decontamination water station) and filter cake (recovery).
