Разработан способ для денитрификации азотсодержащих соединений, присутствующих в водных отходах. Этот способ включает идентификацию типа азотсодержащих соединений, присутствующих в водных отходах, определение их концентраций, приведение в равновесие окисленной и восстановленной форм азота добавлением реагента и нагревание смеси до заданной температуры реакции, примерно от 300 до 600oС, с выделением менее вредных газообразных азота, кислорода, гидроксидов, спиртов и углеводородов.A method has been developed for the denitrification of nitrogen-containing compounds present in aqueous waste. This method involves identifying the type of nitrogen-containing compounds present in the waste water, determining their concentrations, balancing the oxidized and reduced forms of nitrogen by adding a reagent, and heating the mixture to a predetermined reaction temperature, from about 300 to 600 o C, with the release of less harmful nitrogen gases, oxygen, hydroxides, alcohols and hydrocarbons.
