Abstract

Det er beskrevet en fremgangsmåte for rensning av tungmetallholdig spillvann fra behandling og rengjøring av garn fra fiskeri og fiskeoppdrett, utformet slik at såvel det organiske smusset som tungmetallene, spesielt kobber, fjernes på sikker måte. Dette oppnås ved at det fra spillvannet som skal behandles, utfelles i et første trinn suspenderte og/eller emulgerte stoffer under tilsetning av primær-flokkuleringsmidler og flokkuleringshjelpestoffer, og deretter skjer det i et andre trinn en fast-/flytende separasjon, og at det klare vannet som er separert i det andre trinnet og som inneholder de oppløste tungmetallene, deretter behandles i et tredje trinn, at tungmetallene felles ut ved tilsetting av primær-flokkuleringsmidler, organosulfid, lut og flokkuleringshjelpestoffer, og i et etterfølgende fjerde trim separeres utfellingsproduktet, og vannet fra det tredje trinnet skilles ved hjelp av en sedimentasjonsprosess i flokkuleringsslam og klart vann, og hvorved det videre i et femte trinn skjer en slamdrenering slik at slammet som inneholder i det minste tungmetallene, oppviser et faststoffinnhold på mellom 20 og 80%.A method for cleaning heavy metal-containing wastewater from treatment and cleaning of nets from fisheries and fish farming has been described, designed so that both the organic dirt and the heavy metals, especially copper, are safely removed. This is achieved by suspending and / or emulsifying substances suspended in the first stage from the wastewater to be treated with the addition of primary flocculants and flocculants, and then in a second step a solid / liquid separation occurs and the clear the water, which is separated in the second stage and containing the dissolved heavy metals, is then treated in a third stage, that the heavy metals are precipitated by the addition of primary flocculants, organosulfide, lye and flocculants, and in the subsequent fourth trim the precipitate product is separated and the water from the third stage, a sedimentation process is separated into flocculating sludge and clear water, whereby in a fifth step a sludge drainage is carried out so that the sludge containing at least the heavy metals has a solids content of between 20 and 80%.
