Использование: в коммунальном хозяйстве при строительстве и реконструкции очистных сооружений. Сущность: в способе глубокой биологической очистки сточных вод /СВ/, включающем подачу смеси исходных СВ с нитрифицированным активным илом /АИ/ на стадию аэрации с последующим разделением иловой смеси на избыточный и рециркуляционный АИ и осветленные биологически очищенные СВ, подачу смеси исходных СВ с нитрифицированным АИ на стадии аэрации ведут рассредоточенно по всей длине аэротенка, используют фиксированные и свободноплавающие носители для прикрепления на их поверхности микроорганизмов АИ, в качестве свободноплавающих носителей используют взвешенные вещества, поступающие с исходными СВ. Иловую смесь на стадии аэрации делят на два потока, один из которых уплотняют и подают на смешение с исходными СВ в качестве нитрифицированного АИ, а другой разделяют на стадии аэрации в потоке со скоростью не более 1,5 мм/с на рециркуляционный АИ, который под воздействием восходящего водовоздушного потока возвращается на стадию аэрации, и смесь биологически очищенных СВ и избыточного АИ с концентрацией, не превышающей прирост АИ, которую подвергают реагентной обработке с последующим разделением на избыточный АИ и очищенные осветленные воды путем осветления, избыточный АИ уплотняют, а очищенные осветленные воды подвергают фильтрованию.Usage: in the utilities during the construction and reconstruction of sewage treatment plants. Essence: in the method of deep biological wastewater treatment / SV /, which includes the supply of a mixture of the initial CB with nitrified activated sludge / AI / to the stage of aeration with the subsequent separation of the silt mixture into excess and recirculation AI and clarified biologically purified CB At the stage of aeration, AIs are dispersed throughout the length of the aerotank; fixed and free-floating carriers are used to attach AI microorganisms on their surface as free-floating carriers. use suspended substances coming from the original CB. Sludge mixture at the stage of aeration is divided into two streams, one of which is compacted and fed to the mixture with the original CB as nitrified AI, and the other is divided into stages of aeration in the stream with a speed of not more than 1.5 mm / s to the recirculation AI, which ascending water-air flow returns to the stage of aeration, and the mixture of biologically purified ST and excess AI with a concentration not exceeding the increase in AI, which is subjected to reagent treatment, followed by separation into excess AI and purified clarified during dyes by clarification, the excess AI is compacted, and the purified clarified water is filtered.
