Abstract
Wynalazek dotyczy sposobu bioremediacji ziemi mas ziemistych, zanieczyszczonych zwiazkami ropopochodnymi, gdzie w pierwszej fazie pierwszego etapu procesu odpady biologiczne, ulegajace biodegradacji, uklada sie w co najmniej jedna pryzme wzdluz osi kanalów napowietrzajacych, po czym, gdy temperatura nagrzania tej pryzmy osiagnie temperature co najmniej 45°C, naklada sie na nia warstwe ziemi i/lub masy ziemistej, zawierajacej zanieczyszczenia ropopochodne, w proporcji wagowej od 6:4 do 8:2, korzystnie 7:3 i przy temperaturze w tak otrzymanej pryzmie, wynoszacej 37-45°C pozostawia przez okres co najmniej 2 dni. Nastepnie co kilka dni, korzystnie cztery, pryzme miesza sie, spulchnia i nawilza do 39-41% oraz napowietrza sie cisnieniowo w ilosci 10-20 m3, korzystnie 15 m3 powietrza w przeliczeniu na 1000 kg s. m. pryzmy, korzystnie z czestotliwoscia 0,5 godziny napowietrzania i 0,5 godziny przerwy, przy czym proces ten, w zaleznosci od wielkosci pryzmy, prowadzi sie od kilkunastu dni do trzech tygodni, do momentu przeprowadzenia transformacji mikrobiologicznej. W drugiej fazie pierwszego etapu procesu tak uzyskany aktywny kompost inicjujacy miesza sie z ziemia i/lub masami ziemnymi, zawierajacymi zanieczyszczenia ropopochodne, w proporcji wagowej od 6:4 do 8:2, korzystnie 7:3, i podobnie jak w pierwszej fazie pierwszej etapu procesu, uklada sie w co najmniej jedna pryzme oraz wykonuje sie jej napowietrzanie cisnieniowe oraz spulchnianie, przy czym proces ten prowadzi sie w temperaturze nagrzania pryzmy nie mniejszej niz 32°C, do momentu uzyskania ziemi kompostowej, zawierajacej sladowe ilosci zanieczyszczen ropopochodnych, po czym ewentualnie tak otrzymana ziemie kompostowa w ostatnim etapie poddaje sie humifikacji.The invention relates to a method of bioremediation of earth, contaminated with petroleum compounds, where in the first phase of the first stage of the process biodegradable biodegradable waste is arranged in at least one prism along the axis of aeration channels, and then, when the temperature of heating this prism reaches a temperature of at least 45 ° C, a layer of soil and / or earthy mass containing oil-derived impurities is applied to it, in a weight ratio of 6: 4 to 8: 2, preferably 7: 3 and at a temperature in the thus obtained heap of 37-45 ° C for a period of at least 2 days. Then every few days, preferably four, the prism is mixed, loosened and moisturized to 39-41% and pressure aerated in the amount of 10-20 m3, preferably 15 m3 of air per 1000 kg dry prisms, preferably with a frequency of 0.5 hours aeration and 0.5 hour break, the process depending on the size of the pile is carried out from several days to three weeks, until the microbiological transformation is carried out. In the second phase of the first stage of the process, the thus obtained active initiating compost is mixed with soil and / or earth masses containing petroleum impurities, in a weight ratio of 6: 4 to 8: 2, preferably 7: 3, and similarly as in the first phase of the first stage process, it is arranged in at least one pile and its pressure aeration and loosening is carried out, while this process is carried out at the temperature of heating the pile not less than 32 ° C, until compost soil containing trace amounts of oil derivatives is obtained, and then possibly the compost soil thus obtained is subjected to humification in the last stage.
