Abstract
Изобретение относится к биологической обработке осадков из сточных вод, а именно активного ила и первичного осадка. Изобретение может быть применено на сооружениях биологической очистки коммунальных сточных вод, а также сточных вод зоотехнических ферм и предприятий переработки пищевых продуктов. Способ предусматривает смешивание при кратковременной аэрации первичного осадка с анаэробной активностью и активного ила с аэробной активностью при температуре 40...45°С. Смесь выдерживают в мезо-термофильных условиях до ее осветления и расслоения с получением твердого флотирующего вещества, водной фазы и, возможно, органоминерального осадка, и их последующим разделением. Оптимальная продолжительность биологической очистки составляет 16...18 часов при использовании свежего первичного осадка.
