Abstract

Inventia se refera la procedee de purificare a apelor subterane de hidrogen sulfurat si/sau sulfurisi poate fi folosita in procesul de tratare a apelor sau in filtrele autonome pentru purificarea apei. Procedeul, conform inventiei, include purificarea apelor subterane de hidrogen sulfurat si/sau sulfuri prin aerarea lor in prezenta catalizatorilor obtinuti in baza carbunelui activ oxidat, impregnat cu ioni de cupru sau fier, timp de 30...90 min, cu un debit de aer de 10...15 L/ora la 1 g de catalizator, raportul de masa catalizator : apa fiind de 1: (350...450) si pH-ul apei 7,5...8,5. Rezultatul inventiei consta in oxidarea ionilor de sulfura pana la compusi ai sulfului cu grad inalt de oxidare, ce exclude formarea sulfului elementar si posibilitatea colmatarii porilor catalizatorului.
