Abstract
Pronalazak se odnosi na postupak za prečišćavanje vodenih rastvora zagadjenih nitratnim jonima. Ovaj postupak je okarakterisan time što se sastoji u taloženju hidratisanih dvogubih ili mešanih kalcijum nitroaluminata, takvih kao što je, naročito, hidratisani kalcijum mononitroaluminat, dodavanjem bara jednog agensa koji daje elemenat aluminijum i bar jednog agensa koji daje elemenat kalcijum u rastvore koji treba da se obradjuju, pri čemu je ukupan molski odnos elementa aluminijuma prema nitratu, Al/NO3, viši od 1 i ukupan molski odnos kalciuma prema nitratu, Ca/NO3, viši od 2, i što se reakcija taloženja izvodi uz mešanje i pri baznom pH, prvenstveno iznad 10.5. Postupak prema pronalaskuje namenjen, naročito, za obradu zagadjenih voda takvih kao što su gradska otpadna voda i fabričke otpadne prijave vode i na obradu tečnog djubriva.The invention relates to a process for the purification of aqueous solutions contaminated with nitrate ions. This process is characterized in that it consists of precipitating hydrated double or mixed calcium nitroaluminates, such as, in particular, hydrated calcium mononitroaluminate, by adding a bar of one agent giving the element aluminum and at least one agent giving the element calcium to the solutions to be the total molar ratio of aluminum element to nitrate, Al / NO3, is greater than 1 and the total molar ratio of calcium to nitrate, Ca / NO3, is greater than 2, and the precipitation reaction is carried out with stirring and at base pH, preferably above 10.5. The process according to the invention is intended, in particular, for the treatment of polluted waters such as urban waste water and factory waste water applications and for the treatment of liquid fertilizers.
