Abstract

Fremgangsmåte for å eliminere karbon og fosfor og eventuelt også nit- rogen i awann ad biologisk vei, hvor vannet bringes til å sirkulere i biofil- tere med neddykkede filtreringssjikt, som drives under anaerobe betingelser og deretter under aerobe betingelser, eller i motsatt rekkefølge. I et behandlings- system med minst to seriekoblede celler eller biofiltere (for eksempel ett bio- filter som drives under anaerobe betin- gelser og 1-5 biofiltere som drives under aerobe betingelser) foretas en syklisk alternering av anaerobiosefasen og aerobioasefasen, idet strømmen av vann som skal behandles, alltid føres til filteret i anaerobiosefasen. Det vil være fordelaktig at det mellom fasene i syklusen legges inn en relaksasjonsfase hvor det foretas stansning av tilførse- len av vann som skal behandles.A method of eliminating carbon and phosphorus and, optionally, also the nitrogen in wastewater by biological means, whereby the water is circulated in biofilters with submerged filtration layers, operated under anaerobic conditions and then under aerobic conditions, or in reverse order. In a treatment system with at least two serially coupled cells or biofilters (for example, one biofilter operated under anaerobic conditions and 1-5 biofilters operated under aerobic conditions), a cyclic alternation of the anaerobiosis phase and the aerobioase phase takes place, with the flow of water to be treated is always fed to the filter during the anaerobio phase. It would be advantageous to introduce a relaxation phase between the phases of the cycle where the supply of water to be treated is stopped.
