Description

Patentkrav 1. Fremgangsmåde til rensning af vand for forurenende sporstoffer, især arsen, ved samudfældning af sporstofferne under oxidation og udfældning af jernforbindelser med efterfølgende separation, kendetegnet ved, at man forud for oxidationen af tilstedeværende jernforbindelser sætter en supplerende mængde jernforbindelser til vandet. 2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at den supplerende mængde jernforbindelser tilføres ved at vandes bringes i kontakt med er jernholdigt materiale, fortrinsvis jernmalm eller metallisk jern. 3. Fremgangsmåde ifølge krav 2, kendetegnet ved, at vandet ledes gennem et leje af jernmalm, jempartikler, jemspåner eller et andet naturligt jernholdigt materiale med stor overflade. 4. Fremgangsmåde ifølge krav 2 eller 3, kendetegnet ved, at kontakten mellem jem og vand gennemføres ved en naturlig overbrusning af et jernholdigt materiale anbragt i et leje, der er monteret over en belufter. 5. Fremgangsmåde ifølge krav 1, kendetegnet ved, at vandet efter samudfældning af sporstofferne under oxidation og udfældning af jernforbindelser med efterfølgende separation recirkuleres en eller flere gange til fornyet behandling omfattende tilsætning af en supplerende mængde jernforbindelser med efterfølgende oxidation, udfældning af jernforbindelser og separation. 6. Fremgangsmåde ifølge et af de foregående krav, kendetegnet ved, at de samud-fældede sporstoffer omfatter arsen og/eller pesticider. 7. Anlæg til rensning af vand for forurenende sporstoffer ved samudfældning af sporstofferne omfattende en belufter (5) til oxidation og udfældning af jernforbindelser med efterfølgende separation, kendetegnet ved, at der før belufteren (5) er indkoblet en indretning (2, 3, 4) til tilføring af jernforbindelser til vandet. 8. Anlæg ifølge krav 7, kendetegnet ved, at indretningen til tilføring af jernforbindelser omfatter et fordelerorgan (2) til fordeling af vandet over et leje (3) af jempartik-ler, jemspåner, jernmalm eller et andet naturligt jernholdigt materiale med stor overflade samt en eller flere åbninger under lejet til udstrømning af jemberiget vand. 9. Anlæg ifølge krav 7 eller 8, kendetegnet ved, at indretningen (2, 3, 4) til tilføring af jernforbindelser til vandet er anbragt over en hulplade til dannelse af dråber, hvilken hulplade er placeret over et dråbeopdelingsarrangement, der er opbygget af en flerhed af rørelementer i form at rør med rørvægge af trådnet, hvor Tørelementerne ligger i vandrette lag af flere parallelle rørelementer stablet på en sådan måde, at længdeakserne for rørelementeme i et lag ligger vinkelmæssigt forskudt i forhold til længdeakseme for rørelementeme i det eller de naboliggende lag, fortrinsvis med en vinkel på 90°. 10. Anlæg ifølge et af kravene 7-9, kendetegnet ved, at det yderligere omfatter en recirkulationsledning (10) til tilbageføring af det behandlede vand til indretningen (2, 3, 4) til tilføring af jernforbindelser til vandet.
