Abstract

Usage: wastewater treatment by density separation from emulsified oil products, with the exception of clogging with solid suspensions located in the outlets. It can be used in sewage treatment plants. SUMMARY OF THE INVENTION: A rotor is mounted on the drive shaft, including a dc, forming a chamber with partitions and windows, in which primary cleaning occurs when the effluent flows from the nozzle to the annular gap 11 between the partitions 9 and 10 in inclined channels. Water is located under the outer partition 9, since its density is higher than the density of oil products, and oil products enter into adhesion with the material of the partition 10. At the output sections of the free edge of the inclined channels, water is torn off, since its adhesion to the layer of oil products is less than the force of adhesion of oil products to the material partitions 10, and vibrating loads 16 contribute to increased adhesion. Inclined channels increase wastewater treatment time and improve quality. 3 ill.

Description

The invention relates to a technique for treating wastewater by density separation from emulsified oil, with the exception of clogging of feepflbiMH by suspensions in the effluents, and can be used in wastewater treatment plants.

The purpose of the invention is to improve the quality of cleaning.

The execution of channels in the direction opposite to the direction of rotation of the rotor increases the duration of exposure to the drains, and the loads provide vibration effects - all this improves the quality of cleaning.

On Fig, 1 presents the device, a longitudinal section; figure 2 - node 1 in figure 1; in Fig.3 - view A in Fig.2.

A wastewater treatment device comprises a housing 1 with a nozzle 2 for supplying wastewater. mounted in the housing 1 on the drive shaft 3, the rotor, including two disks 4 and 5, mounted one above the other with the formation of the chamber 6, in communication with the pipe 2 for supplying wastewater and having partitions 7 with windows 8 for overflow of the latter, and two conical non-rigid partitions - outer 9 and inner 10. freely suspended on the disks 4 and 5 with a smaller base to form an annular gap 11 in communication with the chamber 6 between the disks 4 and 5, and so that the edge 12 of the internal non-rigid partition is free

the rotor is divided by protrusions 14 into inclined channels 15 in the direction opposite to the direction of rotation of the rotor in the direction of arrow b, while loads 16 are fixed on the inner surface of the inner partition 10 in the area of each channel 15. The housing 1 is made with a tangential branch pipe 17 for water outlet and a branch pipe 18 for oil products .

A wastewater treatment device operates as follows.

Wastewater containing emulsified oil products and solid suspensions enters the cleaning device through the nozzle 2. When the effluent passes through the chamber b, formed by 4 m 5 disks rotating on the drive shaft 3, between the partitions 7 with the overflow through the windows 8, preliminary density separation takes place, which continues in the annular gap 11 between the protrusions in the inclined channels 15. When the rotor rotates along arrow B, the channels 15 are directed in the direction opposite to the direction of rotation, which increases the processing time and accordingly improves the quality of cleaning. The implementation of the partition 10 with loads 16 in the area of each inclined channel 14, ensures the vibration of the wastewater and their separation by density into water located under the partition 9 and oil products that are in engagement with the material of the partition 10. At the outlet of the outlet section of the inclined channel 15 the edge 13 of the outer partition 9 is the separation of water from the surface of oil products that are in adhesion with the material of the partition 10. Water is discharged from the housing 1 along the tangential pipe 17, and the oil continues to move ix down the surface perogo0

birth 10 to the free edge 1.2. When the mass of oil products is reached, at which their inertia force becomes greater. The force of adhesion of the oil products to the material of the partition 10, they break away from the free edge 12, and they are withdrawn from the housing 1 through the tangential nozzle 18 for subsequent disposal.

The technical and economic effect is as follows. which provides wastewater treatment in a device that does not require clogging by solid inclusions, i.e. life cycle continuity.
