Abstract

Fremgangsmåte for behandling av avløpsvann inneholdende kjemisk redu- serbare oppløste organiske og uorganiske forurensninger og suspendert mate- riale i partikkelform eller kolloid form. Prosessen omfatter at vannet bringes i kon- takt med metallisk jern eller jern(ll)-ioner (Fe2+) eller blandinger derav, i nærvær av aktivatormetaller, så som Cu, Pd, Pt, Au, Ag og Ni, eller oksyder, sulfider og andre uløselige forbindelser av disse metaller, og som katalyserer redoksreduk- sjonene gjennomført ved hjelp av jern- eller jern(ll)-reagensene. Produksjonen av jern(lll)-ioner (Fe3*) som et endelig jern-oksydasjonsprodukt muliggjør den sam- tidige koagulering og utfelling av suspenderte kolloide og partikkelformige faststof- fer fra den vandige fase. l tillegg til hovedreduksjons-reaksjonsskjemaet yter sy- stemet en rekke sekundære reaksjoner som involverer jem(ll)- og jem(lll)-ioner tilveiebrakt in-situ, og som muliggjør den samtidige fjerning av spesifikke målforu- rensninger, så som fosfat og hydrogensulfid. Nettoeffekten av en behandling i henhold til foreliggende oppfinnelse er nedgangen i en rekke forskjellige karbon- holdige forurensninger, nitrogenforurensninger og andre målforurensninger til stede i en avløpsvanns-strøm i oppløst form, i kolloid form eller i partikkelform, og den kjemiske omdannelse, vanligvis referert til som "mykning", av forurensninger som ikke er lett bionedbrytbare ved et generelt komplekst sett av reaksjoner og fysikalske prosesser. Som et resultat gjør gjennomføringen av prosessen fsr eller parallelt med konvensjonell biologisk behandling den sistnevnte mer gjennom- førlig, mer effektiv, mer økonomisk med hensyn til såvel kapitalinvestering som driftskostnader, samt gjør det endelige avløpsvann mer kompatibelt med miljø- messige krav.
