Abstract

Oppfinnelsen vedrører en fremgangsmåte til fremstilling av et aggregat hvorved kloakkslam fra et avløpsvannbehandlingsanlegg blandes med et ikke-kullforbrenningsaske-silikoaluminiumoksidholdig avfallsmateriale, blandingen agglomereres til dannelse av et agglomerat og agglomeratet pyrobehandles til dannelse av et aggregat. Avfallsmaterialet kan omfatte forbrenningsovnbunnaske fra kommunalt fastavfall, forbrenningsovnfiygeaske, forbrenningsovnfilterstøv, sementovnstøv, avfallsglass, masovnslagg, ovnstøv og/eller granittsagerester. Fremgangsmåten kan videre omfatte oppmaling av avfallsmaterialet før blanding. Oppmalingen er fortrinnsvis våtoppmaling. Pyrobehandlingen av agglomeratet kan foregå i en roterende ovn. Det resulterende aggregat kan være et aggregat av lettvekt eller normalvekt, sintret eller vitrifisert. Aggregater og fremgangsmåter til fremstilling av aggregater av høy- og lavkalsium-silikoaluminiumoksidholdige materialer er også beskrevet.The invention relates to a process for the preparation of an aggregate in which sewage sludge from a waste water treatment plant is mixed with a non-coal combustion ash-silica-alumina-containing waste material, the mixture is agglomerated to form an agglomerate and the agglomerate is pyro-treated to form an aggregate. The waste material may include incinerator bottom ash from municipal solid waste, incinerator fly ash, incinerator filter dust, cement kiln dust, waste glass, blast furnace slag, kiln dust and / or granite sawdust. The method may further comprise grinding the waste material before mixing. The paint is preferably wet paint. The pyro treatment of the agglomerate can take place in a rotary kiln. The resulting aggregate may be a lightweight or normal weight aggregate, sintered or vitrified. Aggregates and methods for making aggregates of high and low calcium silica alumina-containing materials are also described.
