Description

The invention relates to the technique of cleaning wastewater containing, for example, suspended solids, fats and petroleum products.

A device for cleaning waste water is known, which includes a filtering chamber with granular loading and a fgotat chamber located above each other, with a vacuum chamber for air extraction and removal of foams.

However, such a device is very cumbersome and unreliable in extuation. In addition, the known device only doesn’t significantly reduce the area of wastewater treatment plants and practically does not reduce the ex: Plutatonnyh expenses. During its operation, it is necessary to have an additional, separate stand for the oil trap or O1 tank for preliminary illumination and effluent before flotation.

In the proposed device coaxial. The flotation cell is equipped with an annular chute equipped with a tangential nozzle for supplying waste water. In addition, in the proposed device

The air inlet assembly is located above the filter chamber, which allows the entire volume of air required for flooding to be injected into the loading space of the unCTBo filter.

 This ensures the preconditioning of wastewaters, the compactness of wastewater treatment: the construction of a maximum load of 1 ”1” of 1 kg.
