Description

Изобретение относитс к очистке сточных вол/ в частности к вторичном горизонтальным отстойникам сооружений биологической очистки.The invention relates to the treatment of waste water / in particular to secondary horizontal settlers of biological treatment facilities.

Известно устройство дл сбора .н удалени осадков из горизонталь- , них отстойников, включаквдее подвижную платформу, привод и ИЛОСОСA device is known for collecting .n the removal of sediments from horizontal, their settling tanks, including a mobile platform, a drive and an ILOSOC.

в виде эрлифтов с всасыванвдими наконечниками и поворотными скребками l . .in the form of airlifts with aspiration tips and swivel scrapers l. .

Однако известное устройство не обеспечивает качественной очистки днищ отстойников, так как сосредоточенный отсос ила от сгребающего приспособлени и переваливание ила через скребок взмучивают осадок и ухудшают качество отсто вшейс воды.However, the known device does not provide high-quality cleaning of the bottoms of the settling tanks, since the concentrated suction of sludge from the raking device and the transfer of sludge through the scraper stirs up the sediment and deteriorate the quality of sediment.

Цель изобретени - повышение эффективности использовани устройства за счет равномерного удалени ила по всей ширине отстойника и устранени взмучивани осадка.The purpose of the invention is to increase the efficiency of the use of the device due to the uniform removal of sludge over the entire width of the settling tank and the elimination of the sediment agitation.

Указанна цель достигаетс тем, что вустройстве, содержащем подвижную платформу, привод и илосос, последний выполнен двухсторонним из двух горизонтальных трубопроводов с всасывающими окнами, равномерноThis goal is achieved by the fact that the device containing the mobile platform, the drive and the pump, the latter is made two-way from two horizontal pipelines with suction windows, evenly

расположенными По всей длине и у днища отстойника, центрального вертикального отвод щего коллектора, присоединенного к трубопроводам, и переключающего клапана, установленного в месте присоединени коллектора к трубопроводам.located along the entire length and at the bottom of the settler, a central vertical outlet manifold connected to the pipelines, and a switching valve installed at the point of the collector connection to the pipelines.

На фиг. 1 изображено предлагае10 мое устройство, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1; на фиг.4 - фрагмент устройства в .плане.FIG. 1 shows the proposed 10 my device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; figure 4 is a fragment of the device in the plan.

Устройство дл удалени актив15 ного ила из вторичных горизонтальных отстойников представл ет собой узел 1 отвода активного ила, выполненный в виде размещенного по всей пшрине отстойника двухстороннего The device for removing activated sludge from secondary horizontal clarifiers is an active sludge withdrawal unit 1, made in the form of a two-sided decanter

20 илососа 2 со всасывающими окнами 3, которые через два трубопровода 4, св заны общим вертикальным коллек тором 5.20 silos 2 with suction ports 3, which, through two pipes 4, are connected by a common vertical collector 5.

Claims

A device for removing active sludge is mounted on a trolley 6 installed with the possibility of reciprocating motion along rails 7 fixed on the longitudinal walls of the settling tank by means of a self30. stand-alone actuator. In order to ensure one-sided operation of the device during the reciprocating movement of the trolley b, a switching valve 8 is installed at the point of connection of the pipeline 4 to the collector 5. An axial axial axle (not shown) or a siphon 9 is installed to defend the activated sludge. , To regulate the amount of activated sludge at the point of connection of the sludge pumps to the pipelines 4, a control valve 10 is installed, controlled from the truck b. Tray 11 for removal of activated sludge is placed along the longitudinal wall of the sump. The device works as follows. When moving the device to remove the active sludge from the left, the active sludge under vacuum, create a siphon or pump, enters the right windows of the sludge pump 2 and through the pipe 4 and the common collector 5 take it into the tray. When sucking, sieves are siphoned from the tray into which auger pump or er-. the elevator is being pumped. With an oTcocfe pump, the sediment from the tray flows directly into the air tank. When the device moves from right to left, the activated sludge enters the left-hand windows of the ilosos. The proposed device will allow leT to increase the efficiency of wastewater treatment due to the uniform removal of sludge over the entire width of the settling tank and, in addition, to eliminate residues in horizontal septic tanks. The invention includes a device for removing activated sludge from secondary horizontal clarifiers, including a mobile platform, drive and sludge, characterized in that, in order to increase the efficiency of use by uniformly removing sludge throughout the thiirin of the settler and eliminating Tuddling. from two horizontal pipelines with suction windows evenly spaced along the entire length and at the bottom of the settling basin, a central vertical drainage collector connected to t uboprovodam and switches, valves, installed. at the point of connection of the collector to the pipelines.
