Abstract

Sposób higienizacji osadów ściekowych z udziałem wapna palonego (CaO), w którym odwodniony osad ściekowy poddaje się działaniu wapna palonego (CaO) w procesie lasowania wapna palonego (CaO), charakteryzuje się tym, że przed procesem lasowania (15) osad ściekowy poddaje się procesowi hydratacji wstępnej (13), w którym odwodniony osad ściekowy o zawartości suchej masy wynoszącej od 15% wag. do 25% wag. miesza się z wapnem palonym (CaO) w stosunku wagowym nie przekraczającym 0,9 kg CaO/1 kg suchej masy osadu, nie dopuszczając do homogenizacji osadu ściekowego. Przedmiotem zgłoszenia jest także przedstawiony na rysunku układ do higienizacji osadów ściekowych z udziałem wapna palonego (CaO) oraz system charakteryzujący się tym, że układ do wymuszania obiegu powietrza zawiera wentylator promieniowy.The method of hygienization of sewage sludge with the participation of quicklime (CaO), in which the dehydrated sewage sludge is subjected to the action of quicklime (CaO) in the process of burning quicklime (CaO), is characterized by the fact that before the process of foresting (15) the sewage sludge is subjected to the process pre-hydration (13), in which dewatered sludge with a dry matter content of 15% by weight up to 25 wt. mixes with quicklime (CaO) in a weight ratio not exceeding 0.9 kg CaO / 1 kg dry sludge, preventing the sludge from homogenizing. The subject of the notification is also the sewage sludge hygienization system with the participation of quicklime (CaO) presented in the figure and a system characterized in that the system for forcing air circulation contains a radial fan.
