Abstract

W sposobie otrzymywania nawozu mineralno-organicznego osad sciekowy w pierwszym etapie higienizacji przegrzewa sie w warunkach silnie kwasnego odczynu wywolanego dodaniem stezonego kwasu siarkowego oraz w warunkach wysokiej temperatury i cisnienia spowodowanej reakcja mieszanie sie kwasu z woda, a nastepnie podtrzymanej egzotermiczna reakcja zobojetniania kwasu zwiazkiem magnezu, a w drugim etapie proces wywolany jest przebiegiem reakcji Fentona, której wywolany stres oksydacyjny potegowany jest uzyciem mikrofal.In the method of obtaining mineral-organic fertilizer, the sewage sludge in the first stage of hygienization is overheated under conditions of a strongly acidic reaction caused by the addition of concentrated sulfuric acid and under high temperature and pressure caused by the reaction of mixing acid with water, followed by an exothermic acid neutralization reaction with a magnesium compound, and in the second stage the process is triggered by the Fenton reaction, whose oxidative stress is triggered by the use of microwaves.
