Abstract

Przedmiotem wynalazku jest pellet z mieszaniny otrąb pszennych i suchych osadów ściekowych, o poprawionej wytrzymałości mechanicznej, uszlachetniony kompozycją dodatków zawierającą wapno palone oraz lignosulfonian wapnia, charakteryzujący się tym, że jest mieszaniną otrąb pszennych i suchych osadów ściekowych zawierającą suche osady ściekowe oraz otręby pszenne w stosunku masowym suchych osadów ściekowych do otrąb pszennych wynoszącym od 1: 99 do 1: 4, zawierającą od 0,5 do 2% (m/m) kompozycji wapna palonego oraz lignosulfonianu wapnia w przeliczeniu na masę pelletu, w której to kompozycji stosunek masowy wapna palonego do lignosulfonianu wapnia wynosi 1: 1.The subject of the invention is a pellet made of a mixture of wheat bran and dry sewage sludge, with improved mechanical strength, enriched with an additive composition containing quicklime and calcium lignosulphonate, characterized by the fact that it is a mixture of wheat bran and dry sewage sludge containing dry sewage sludge and wheat bran in the ratio weight of dry sewage sludge to wheat bran ranging from 1: 99 to 1: 4, containing from 0.5 to 2% (m / m) of the quicklime composition and calcium lignosulfonate based on the weight of pellets, in which composition is the weight ratio of quicklime for calcium lignosulfonate is 1: 1.
