Abstract

Настоящее изобретение относится к способу обработки сточных вод, включающему стадию контактирования, на которой сточные воды контактируют с бактериями, удерживаемыми на поверхности подложки, причем концентрацию растворенного кислорода в сточных водах поддерживают на уровне 2,0 мг/л или ниже; стадию аэрации, на которой через сточные воды, прошедшие стадию контактирования, пропускают газ, причем при прохождении сточными водами стадии аэрации концентрацию растворенного кислорода в сточных водах понижают; стадию отстаивания, на которой сточные воды, прошедшие стадию аэрации, практически разделяют на очищенную воду и ил; и стадию рециркуляции ила, на которой по меньшей мере часть ила со стадии отстаивания направляют на стадию контактирования. Изобретение относится также к технологической установке, на которой может быть осуществлен вышеупомянутый способ.
