Abstract

Przedmiotem wynalazku jest pellet z mieszaniny słomy i suchych osadów ściekowych, o poprawionej wytrzymałości mechanicznej, uszlachetniony kompozycją dodatków zawierającą wapno palone oraz lignosulfonian wapnia, charakteryzujący się tym, że jest mieszaniną słomy i suchych osadów ściekowych zawierającą suche osady ściekowe oraz słomę w stosunku masowym suchych osadów ściekowych do słomy 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 pellet made of a mixture of straw 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 straw and dry sewage sludge containing dry sewage sludge and straw in the mass ratio of dry sludge waste water to straw ranging from 1: 99 to 1: 4, containing from 0.5 to 2% (m / m) of the quicklime and calcium lignosulfonate composition based on the weight of the pellets, in which the weight ratio of quicklime to calcium lignosulfonate is 1: 1.
