Abstract

Przedmiotem wynalazku jest sposób mikrobiologicznego oczyszczania biogazu powstającego w procesie fermentacji metanowej osadów organicznych w zbiorniku fermentacyjnym, polegający na usuwaniu zanieczyszczeń, zwłaszcza H2S, w warunkach beztlenowych z wykorzystaniem instalacji opatrzonej w biofiltr wypełniony złożem biologicznym zraszanym pożywką mineralną, który zawiera immobilizowane mikroorganizmy zdolne do rozkładu związków siarki. Sposób charakteryzuje się tym, że złoże biologiczne zrasza się pożywką w postaci roztworu zawierającego azotany soli metali alkalicznych I i II grupy układu okresowego, przy czym stężenie jonów azotanowych w pożywce zawiera się w granicach od 20 do 2500 mg/l, podczas gdy stężenie doprowadzanego do instalacji H2S wynosi 100 - 3000 ppm.The subject of the invention is a method of microbiological purification of biogas formed in the process of methane fermentation of organic sludge in a fermentation tank, consisting of removing impurities, especially H2S, in anaerobic conditions using a system equipped with a biofilter filled with a biological bed sprinkled with mineral medium, which contains immobilized microorganisms capable of decomposing compounds sulfur. The method is characterized in that the biological bed is sprinkled with the nutrient solution in the form of a nitrate-containing solution of alkali metal salts of Group I and II of the Periodic Table, the concentration of nitrate ions in the medium is in the range from 20 to 2500 mg / l, whereas the concentration H2S installation is 100 - 3000 ppm.
