Description
водослив перегородки 6. Посто нна , в автоматическом режиме, циркул ци иловой смеси через верхнюю зону илосборной камеры 1 приводит к налолнецию ее илом и его уплотнению.the weir of the partition 6. The constant, in the automatic mode, the circulation of the sludge mixture through the upper zone of the sludge collecting chamber 1 leads to its maintenance with sludge and its compaction.
Если отделение ила цриостанавливаетс на длительное врем во избежание вспухани его, он выпускаетс из илосборной камеры 1 в аэротенк, дл чего открываетс затвор на циркул ционном трубопроводе 14, при этом используетс эффект эжекции. После накоплени и уплотнени ила включаетс в работу илоотвод ща (флотационна ) камера 2, дл чего на трубопроводе 11 открываетс задвижка, выпускаетс жидкость, наход ща с в лотке 10, вследствие чего создаетс перепад между уровнем жидкости в аэротенке и уровнем в илоотвод щей камере 2 и илосборной камере 1, а уплотненный им через канал 7 выдавливаетс в илоотвод щую камеру. Одновременно с этим открываетс задвижка на трубопроводе 8 рабочей жидкости.If the sludge separator is decanted for a long time in order to avoid swelling, it is discharged from the sludge chamber 1 into the aeration tank, for which the shutter opens on the circulation pipe 14, using the ejection effect. After accumulation and compaction of the sludge, the sludge (flotation) chamber 2 is activated, for which the valve 11 is opened in the pipe 11, the fluid in the chute 10 is discharged, resulting in a difference between the level of the liquid in the aeration tank and the level in the sludge discharge chamber 2 and the sludge collecting chamber 1, and compacted by it through the channel 7 is squeezed into the sludge discharging chamber. At the same time, the valve opens in the pipeline 8 of the working fluid.
Пузырьки воздуха, образующиес при выпуске рабочей жидкости, захватывают частицы ила, поднимают их к поверхности жидкости, где и уплотн ют до влажности 94-95%, а отведение ила осуществл етс по гибкому щлангу 12.Air bubbles that form when the working fluid is discharged capture the sludge particles, lift them to the surface of the fluid, where they seal to a moisture content of 94-95%, and sludge discharge takes place along the flexible hose 12.
Применение данного устройства дл очистки сточных вод позвол ет подавать на флотацию иловую смесь более высокой концентрации , чем в аэротенке, что повышает эффект флотации в 1,5-2 раза, соответственно снижа расход рабочей жидкости. The use of this wastewater treatment device allows the flotation of a sludge mixture of a higher concentration than in the aeration tank, which increases the flotation effect by 1.5-2 times, respectively, reducing the flow rate of the working fluid.
Конструкци предлагаемого устройства дл очистки сточных вод позвол ет выделить избыточную часть ила флотационнымThe design of the proposed wastewater treatment plant makes it possible to isolate the excess sludge from flotation
/ff/ ff
способом или эрлифтом непосредственно из иловой смеси аэротенка после предварительного ее уплотнени до влажности, близкой к влажности ила вторичного отстойника , уменьшить объем вторичных отстойников , отказатьс от строительства илоуплотнителей как самосто тельных сооружений , получить избыточный ил влажностью 94-95%, что в конечном итоге снижает затраты на его дальнейшую обработку .method or air lift directly from the aerotank sludge mixture after its pre-compaction to a moisture close to the sludge of the secondary settling tank, reduce the volume of the secondary settling tanks, refuse construction of sludge compactors as independent structures, get excess sludge with humidity of 94-95%, which ultimately reduces the cost of its further processing.
