Abstract

Изобретение относитс к устройствам дл очистки сточных вод от эмульгированных и коллоидных загр знений, взвешенных частиц. Целью изобретени вл етс повышение надежности работы устройства путем направленного сгона и сбора пенного продукта. Устройство содержит цилиндро- конический корпус 1, установленный внутри него цилиндр 2, аэраторы 3, размещенные в цилиндре2, пеносборник4, расположенный коаксиально цилиндроконическому корпусу 1 и установленный внутри цилиндра 2. Внутри цилиндра также установлена вертикальна перегородка 5, выполненна в виде спирали Архимеда. При этом нижн кромка ее расположена на уровне жидкости, внешний конец ее ориентирован против направлени движени жидкости и прикреплен к стенке цилиндра 2, а внутренний прикреплен к верхней кромке пеносборника 4. Патрубок 6 тангенциального подвода исходной сточной воды введен в цилиндр 2 над аэраторами 3. Отвод очищенной воды из устройства осуществл етс по патрубку 8, отвод осадка - по патрубку 9, а пенного продукта из пеносборника4-по патрубку 10. Пенный продукт, образующийс при флотации сточной воды на ее поверхности, скользит по перегородке 5 и направл етс внутрь нее к пеносборнику 4, из которого по патрубку 10 отводитс из устройства: Изобретение позвол ет отказатьс от специальных пено- гонных устройств. 3 ил.The invention relates to wastewater treatment plants for emulsified and colloidal contaminants, suspended particles. The aim of the invention is to increase the reliability of the device by directing the suction and collecting the foam product. The device contains a cylindro-conical body 1, a cylinder 2 installed inside it, aerators 3 placed in cylinder 2, a foam container 4 located coaxially to a cylindrical body 1 and installed inside cylinder 2. Inside the cylinder there is also a vertical partition 5 designed in the form of an Archimedes spiral. At the same time, its lower edge is located at the liquid level, its outer end is oriented against the direction of fluid movement and is attached to the wall of cylinder 2, and the inner edge is attached to the upper edge of the foam collector 4. Pipe 6 of the tangential supply of source waste water is introduced into cylinder 2 above aerators 3. Withdrawal purified water from the device is carried out through pipe 8, sludge is withdrawn through pipe 9, and froth product from the foam tank 4 through pipe 10. The foam product formed during the flotation of waste water on its surface slides along eregorodke 5 and is directed inwardly therefrom to Skimmer 4, from which is withdrawn through conduit 10 from the apparatus: The invention allows to dispense from special foaming of chasing devices. 3 il.

Claims

Claim

A device for treating wastewater containing a cylindrical-conical housing in which a cylinder, aerators, and a pipe-duct tangential are installed coaxially. A water supply installed above the aerators, pipes for removing purified water, sludge and foam product, a foam collector, characterized in that. in order to increase reliability in work by providing directional conveying and collecting foam product, it is equipped with a vertical partition made in the form of an Archimedes spiral and installed in the cylinder, while the lower edge of the vertical partition is located at the liquid level, its outer end is attached to the cylinder wall and oriented against the direction of fluid movement in the cylinder, the inner end of the vertical partitions is attached to the upper part of the foam collector located coaxially to the cylindrical-conical body, and the tangential water inlet is attached to the cylinder.
