Claims (1)

Способ физико-биологической очистки сточных вод и линия для его осуществления относятся к очистке городских и сельскохозяйственных стоков (С) и позволяют повысить эффективность очистки на единицу объема очистных сооружений. Способ включает отстаивание С, первую аэрацию (А) и биохимическое окисление в аэротенке (АТ), вторую А, отделение избыточного активного ила (АИ), регенерацию избыточного АИ, смешивание регенерированного АИ с рабочим АИ и неочищенными С, при этом после отстаивания проводят дополнительную А, рабочий АИ на смешивание подают путем возврата его из потока после дополнительной А перед первой АС и биохимическим окислением в аэротенке, а суммарную концентрацию АИ в объеме смешивания выдерживают в пределах 16 - 40 г/л. Линия включает соединенные между собой трубопроводами (Т) отстойник (О), флотаторы (Ф) первой и второй ступени, содержащие шламовые карманы и сливные устройства, АТ, напорные резервуары с насосами и эжекторами, установленными перед каждым Ф, а также входной и выходной Т, при этом О снабжен вертикальной перегородкой, разделяющей его на камеру перемешивания и камеру отстаивания, АТ установлен между флотаторами, шламовые карманы флотаторов снабжены Т, соединяющими их с камерой перемешивания О, а камеры смешения эжекторов сообщаются с атмосферой.The method of physico-biological wastewater treatment and the line for its implementation relate to the treatment of urban and agricultural wastewater (C) and can improve the cleaning efficiency per unit volume of treatment facilities. The method includes sedimentation of C, first aeration (A) and biochemical oxidation in the aeration tank (AT), second A, separation of excess activated sludge (AI), regeneration of excess AI, mixing the regenerated AI with working AI and untreated C, and after settling, additional A, the working AI for mixing is fed by returning it from the stream after additional A before the first AC and biochemical oxidation in the aeration tank, and the total concentration of AI in the mixing volume is kept within 16-40 g / l. The line includes interconnected pipelines (T) sump (O), floaters (F) of the first and second stages, containing sludge pockets and drain devices, AT, pressure tanks with pumps and ejectors installed in front of each F, as well as inlet and outlet T , while O is provided with a vertical partition dividing it into the mixing chamber and the settling chamber, AT is installed between the flotation units, the slime pockets of the flotation units are equipped with T connecting them with the O mixing chamber, and the mixing chambers of the ejectors communicate with atmospheres d.
