Description
Technical field
The present invention relates to a kind of PVB sewage treatment equipment, particularly relate to a kind of lower concentration PVB sewage treatment equipment based on ion-exchange.
Background technology
Polyvinyl butyral acetal is called for short PVB, be the condenses that polyvinyl alcohol and butyraldehyde produce under the catalysis of hydrochloric acid, a large amount of PVB rinse water can be produced in PVB production process, containing butyraldehyde, polyvinyl butyral acetal, polyvinyl alcohol, chlorion, hydrogen ion in its waste water, complicated component, pH value is low.It is up to standard that simple Bian biological process or physics, chemical method are all difficult to process, and processing cost is high and not easily promote.Also less to the research of this waste water treatment process both at home and abroad, also not having at present can the lower concentration PVB sewage treatment equipment of head it off very well.
Summary of the invention
Object of the present invention is just to provide a kind of lower concentration PVB sewage treatment equipment based on ion-exchange to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of lower concentration PVB sewage treatment equipment based on ion-exchange, for the treatment of the waste water in water reservoir and by process after water enter rare Water circulation pond, comprise sandfiltration pot, cation bed, carbon dioxide cleaner, anion bed, macroporous resin column and activated charcoal filter, the water inlet of described sandfiltration pot is the water inlet of described lower concentration PVB sewage treatment equipment, the water outlet of described sandfiltration pot successively with described cation bed, described carbon dioxide cleaner, described anion bed, described macroporous resin column is connected with described activated charcoal filter, the water outlet of described activated charcoal filter is the water outlet of described lower concentration PVB sewage treatment equipment.
In said structure, fill quartz sand in sandfiltration pot, for being filtered down by insoluble substance; Cation bed and cation exchanger, also referred to as pressure filter, for removing the sodium ion in waste water; Carbon dioxide cleaner is the equipment that the degassed mode of a kind of air blast removes water quality free carbon dioxide, for removing most of basicity in waste water; Anion bed and anion exchanger, for removing most chlorion and a small amount of butyraldehyde; Namely macroporous resin column is filled with the Filter column of macroporous resin, for removing most of butyraldehyde; Namely activated charcoal filter is the strainer of filtration medium with gac, for adsorbing remaining low levels organism.Sandfiltration pot, cation bed, carbon dioxide cleaner, anion bed, macroporous resin column and activated charcoal filter are existing conventional equipment.
In order to raise the efficiency, described cation bed, described anion bed and described macroporous resin column are two, realize in parallel or be connected in series by regulated valve.
Beneficial effect of the present invention is:
Sand filtration, cation and anion exchange, macroporous resin adsorption combine by the present invention, and achieve the efficient process of lower concentration PVB waste water, effluent characteristics is up to standard; Reuse after rare water desalination after process, is conducive to reducing running cost; Whole equipment non-wastewater discharge, externally discharges without poisonous and harmful solid waste, is beneficial to environmental protection; Adopt two cation beds, two anion beds and two macroporous resin column, be conducive to increasing water quality and processing efficiency, and extend the work period, save regeneration expense.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the lower concentration PVB sewage treatment equipment based on ion-exchange of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, lower concentration PVB sewage treatment equipment based on ion-exchange of the present invention, for the treatment of the waste water in water reservoir and by process after water enter rare Water circulation pond, comprise sandfiltration pot, cation bed, carbon dioxide cleaner, anion bed, macroporous resin column and activated charcoal filter, the water inlet of sandfiltration pot is the water inlet of described lower concentration PVB sewage treatment equipment, the water outlet of sandfiltration pot is connected with cation bed, carbon dioxide cleaner, anion bed, macroporous resin column and activated charcoal filter successively, and the water outlet of activated charcoal filter is the water outlet of described lower concentration PVB sewage treatment equipment.
In order to raise the efficiency, cation bed, anion bed and macroporous resin column are two, realize in parallel or be connected in series by regulated valve.This structure does not illustrate in the drawings, and explanation can be understood.
As shown in Figure 1, during application, the water inlet of sandfiltration pot is connected with the water outlet of water reservoir, the water outlet of activated charcoal filter is connected with the water inlet in rare Water circulation pond, and lower concentration PVB storage of waste water is in water reservoir, and its water quality is as follows: CODcr=900mg/L, Cl-=200mg/L, containing a small amount of insoluble substance SS, waste water enters sandfiltration pot by lift pump, is filtered down by insoluble substance SS; Filter water outlet and enter cation bed (selecting hydrogen form cation exchange column), in waste water, sodium ion is exchanged by hydrogen ion; In waste water, hydrogen ion increases, and cation bed water outlet removes most of basicity by carbon dioxide cleaner, alleviates anion bed load; Carbon dioxide cleaner water outlet enters anion bed (i.e. anion-exchange column), removes most chlorion and a small amount of butyraldehyde by anionresin; Anion bed water outlet enters macroporous resin column (also claiming macroporous resin adsorption post), and remove most of butyraldehyde by macroporous resin adsorption effect, so far CODcr clearance reaches 95 more than ℅; Macroporous resin treatment water outlet enters activated charcoal filter, by the low levels organism that gac effect absorption is remaining; Activated charcoal filter water outlet CODcr=90mg/L, specific conductivity=17us/cm, chlorion=6mg/L, without insoluble substance SS, then water outlet enters rare Water circulation pond, by desalination reuse after the desalted water processing system of workshop.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
