Description

40 456 087 2 uppfinningen skall zeoliten ha poröppningar av storleken 1-1D Å, före- trädesvis 5-10 Å. According to the invention, the zeolite should have pore openings of the size 1-1D Å, preferably 5-10 Å.

Uppfinningen skall i det följande närmare beskrivas medelst nâgra utföringsexempel samt med hänvisning till bifogade ritning, på vilka fig 1 visar en anläggning med förbehandlingssteg enligt uppfin- ningen, fig 2 ett arrangemang för regenerering av adsorptionsmaterialet och fig 3 en anläggning innefattande två adsorptionsbäddar.The invention will be described in more detail below by means of some exemplary embodiments and with reference to the accompanying drawing, in which Fig. 1 shows a plant with pretreatment steps according to the invention, Fig. 2 an arrangement for regenerating the adsorption material and Fig. 3 a plant comprising two adsorption beds.

Vid försök med anläggningen enligt fig 1 tillfördes avloppsvatten innehållande 3 9/1 fenol genom ledningen 22 en behållare 1 innehållande ett filter med det enligt uppfinningen använda zeolitmaterialet 9. Genom anordnandet av ett sådant adsorptionssteg före aktivslamanläggningen kunde avloppsvattnets fenolhalt reduceras till 20 mg/1. Detta förbehandlade av- loppsvatten överfördes sedan till aktivslamanläggningen 5, i vilken luft inblåstes genom i behållarens botten anordnat rörsystem, vilket schema- tiskt i figuren angivits med hänvisningsbeteckningen 11. Efter reningen i behållaren 5 överfördes vattnet genom ledningen 13 till en slamavskil- jare 6 och genom ett överlopp kunde sedan renat vatten tas ut genom led- ningen 16. I det renade vattnet kunde någon fenol ej påvisas. På vanligt sätt var slamavskiljaren 6 vid dess botten försedd med en rörledning 12 för att möjliggöra en âterföring av slam till aktivslamanläggningen 5.In experiments with the plant according to Fig. 1, wastewater containing 39/1 phenol was fed through line 22 to a container 1 containing a filter with the zeolite material 9 used according to the invention. This pretreated wastewater was then transferred to the activated sludge plant 5, in which air was blown in through a pipe system arranged in the bottom of the container, which is schematically indicated in the figure by the reference numeral 11. After purification in the container 5, the water was transferred through line 13 through an overflow, purified water could then be taken out through line 16. In the purified water, no phenol could be detected. In the usual way, the sludge separator 6 at its bottom was provided with a pipeline 12 to enable a return of sludge to the activated sludge plant 5.

Genom avlägsnande av den större mängden fenol i zeolitfiltret 9 kunde den återstående delen fullständigt förbrukas av bakterierna í aktiv- slamanläggningen 5. Avloppsvattnets uppehållstid i zeolitfiltret 9 var ca 15 minuter och i aktívslamanläggningen ca 2 timmar.By removing the larger amount of phenol in the zeolite filter 9, the remaining part could be completely consumed by the bacteria in the activated sludge plant 5. The residence time of the wastewater in the zeolite filter 9 was about 15 minutes and in the activated sludge plant about 2 hours.

Efter en tids användning kommer zeolitfiltret att mättes med fenol.After a period of use, the zeolite filter will be measured with phenol.

I detta läge måste filtret tas ur bruk och regenereras. Medelst en anlägg- ning enligt fig 1 kan detta lätt ordnas, t ex på så sätt som visats i fig 2.In this mode, the filter must be taken out of service and regenerated. By means of a plant according to Fig. 1, this can be easily arranged, for example in the manner shown in Fig. 2.

Genom att - såsom det visas i fig 2 - anordna en särkild led- ning 17 från slamavskiljarens 17 överlopp till zeolítfiltret 2 under sam- tidigt frånkopplande av tillförseln av avloppsvatten, kan renat vatten bringas att strömma genom filtret och därigenom åstadkomma en regenere- ring. Det filterbädden tillförda, rena vattnet upptar fenol från zeolit- materialet och tillför detta aktívslamanläggningen i en sådan mängd per tidsenhet att bakteriekulturen i anläggningen 5 förmår nedbryta fenolen.By - as shown in Fig. 2 - arranging a special line 17 from the overflow of the sludge separator 17 to the zeolite filter 2 while simultaneously disconnecting the supply of waste water, purified water can be caused to flow through the filter and thereby effect a regeneration. The pure water supplied to the filter bed absorbs phenol from the zeolite material and supplies this to the activated sludge plant in such an amount per unit time that the bacterial culture in the plant is able to degrade the phenol.

Sedan vattnet cirkulerats genom ledningarna 14 och 17 en tillräcklig lång tid för åstadkommandet av zeolitmaterialets rening, avbrytes proceduren och man återgår till rening av avloppsvattnet enligt det visade arrange- manget i fig 1. 3? 456 osv Anläggningen enligt fig 2 är på samma sätt som i fig 1 försedd med luftinblåsning genom ledningen 11 samt slamåterföring genom ledningen 12.After the water has been circulated through the lines 14 and 17 for a sufficiently long time for the purification of the zeolite material, the procedure is interrupted and the purification of the waste water is resumed according to the arrangement shown in Fig. 1. 3? 456 etc. The plant according to Fig. 2 is in the same way as in Fig. 1 provided with air blowing through the line 11 and sludge return through the line 12.

Med användning av anläggningar som skisserats i fig 1 och 2 kan rening av avloppsvatten innehållande toxiska ämnen genomföras på ett enkelt sätt. Vill man emellertid ytterligare effektivisera behandlingen, kan man använda en kontinuerlig metod. Exempel på en sådan har visats i fig 3.Using plants outlined in Figures 1 and 2, wastewater treatment containing toxic substances can be carried out in a simple manner. However, if you want to further streamline the treatment, you can use a continuous method. Examples of such have been shown in Fig. 3.

Enligt fig 3 anordnas två stycken zeolitfilter 3 resp 4. Det av- loppsvatten som skall renas ledes till zeolitbädden 0 genom ledningen 23. Även i detta Fall utfördes försöket med ett vatten innehållande det toxiska ämnet fenol och härvid i en mängd av 3 g/1. Efter att ha genomströmmat zeolitbädden 10 föres vattnet genom ledningen 20 till en aktivslamanlägg- ning 5. En analys av vattnet visade att det efter zeolitbädden innehöll mindre än 20 mg fenol per liter. På samma sätt som beskrivits i samband med fig 1 och 2 fördes det renade vattnet genom ledningen 15 till en slamav- skiljare 8. Det från avskiljaren kommande, renade vattnet togs dels ut genom ledningen 19 såsom färdigbehandlat vatten, dels fördes genom led- ningen 18 till zeolitbädden 9 i behållaren 3 för regenerering av materialet.According to Fig. 3, two zeolite filters 3 and 4, respectively, are arranged. The waste water to be purified is led to the zeolite bed 0 through the line 23. Also in this case the experiment was carried out with a water containing the toxic substance phenol and in this case in an amount of 3 g / l. . After flowing through the zeolite bed 10, the water is passed through the line 20 to an activated sludge plant 5. An analysis of the water showed that after the zeolite bed it contained less than 20 mg of phenol per liter. In the same way as described in connection with Figs. 1 and 2, the purified water was passed through the line 15 to a sludge separator 8. The purified water coming from the separator was partly taken out through the line 19 as finished treated water, and partly passed through the line 18. to the zeolite bed 9 in the container 3 for regenerating the material.

Utloppet från behållaren 3 fördes sedan tillbaka till anläggningen S genom ledningen 21. Även här är anläggningen 5 försedd med luftinblåsning 11 och en slamåterföring 12 från slamavskiljaren 8. Zeolitmaterialet i behållaren 4 har i fig 3 givits hänvisningsbeteckningen 10.The outlet from the container 3 was then returned to the plant S through the line 21. Here too the plant 5 is provided with air injection 11 and a sludge return 12 from the sludge separator 8. The zeolite material in the container 4 has been given the reference designation 10 in Fig. 3.

Genom användning av en hydrofob zeolit enligt föreliggande upp- finning åstadkommer man en avsevärd förbättrad rening av ett toxiskt av- loppsvatten. Systemet får en hög resistensnívå mot gifter och mot föränd- ringar i vattnets sammansättning. Samtidigt ges möjlighet till utnyttjande av ett större urval av biologiska processer och därmed ett optimalt system ur ekonomisk synpunkt.By using a hydrophobic zeolite according to the present invention, a considerably improved purification of a toxic wastewater is achieved. The system has a high level of resistance to toxins and to changes in the composition of the water. At the same time, it is possible to utilize a larger selection of biological processes and thus an optimal system from an economic point of view.

Uppfinningen är icke begränsad till den beskrivna uföringsformen, utan kan varieras inom ramen för uppfinningstanken. Det är således även möjligt att använda zeoliten i en fluidiserad bädd eller som beläggning på ytor.The invention is not limited to the described embodiment, but can be varied within the scope of the inventive idea. It is thus also possible to use the zeolite in a fluidized bed or as a coating on surfaces.
