Abstract

The invention relates to devices D. for wastewater treatment and is intended for use in sewage treatment plants for industrial and industrial wastewater from suspended substances. The goal is to increase the efficiency of wastewater treatment. The application of the proposed design of the device allows for the continuous forced removal of sediment from a conical partition 11, which the device is equipped with, which prevents it from sticking and rotting and contributes to additional clarification of the liquid as it passes through a layer of suspended sediment that is forcibly removed through flexible pipe 12 attached by insert 16 to the conical partition. Thanks to the rods 15 attached to the socket 13, the sediment is transported through the partition 11 to the socket 13 and through the nozzle 12 enters the lower part of the device. 1 il. with to (L

j The invention relates to devices for the treatment of wastewater from suspended Valuable substances and can be used in domestic and industrial wastewater treatment plants.

The aim of the invention is to increase the efficiency of wastewater treatment.

The drawing shows the proposed device, longitudinal section.

The wastewater treatment device contains a cylindrical housing 1, a supply pipe 2 of the source water, a distribution duct 3, a perforated pipeline

4 collecting purified water, piping

5 water discharge pipe 6 drainage sediment, a cylindrical partition 7 the Central pipe 8, collecting tray 9 chipper -10, conical partition

11, dividing the case into two rusas and inclined to the center, attached to the case 1 and located under the partition 7, a flexible patrub.ok 12 with the upper 13 and the lower 14 sockets, inside which is located the central tube 8, rods 15, attached to the upper bell 13 and located above the partition 11, concentrically located relative to the pipe 8 flexible insert 16, through which the pipe 12s sockets 13 and 14 is attached to the partition 11, with the lower socket 14 located above the baffle 10, and the lower edge of the central pipe located under the partition 11 between the upper and lower sockets.

The original waste water through the pipe 2 enters the distribution tray 3, through which it is evenly distributed over the entire surface area of the liquid between the housing 1 and the partition 7, and moves down to the conical partition 11. Then the flow of liquid changes the direction of movement and moves upwards to the collecting tray 9 under the cylindrical partition 7, during this time the clarification of the sewage from suspended weeds that settle on the conical partition 11 occurs. The clarified waste water from the collecting tray 9 enters the center nuyu tube 8 and travels to the bottom of the device to the bump stop 10, from which reflecting Referring fluid flow changes direction from downward movement to upward present. The liquid exiting the central tube 8 passes between the baffle 10 and the lower bell 14 of the flexible nozzle 12, the latter making minor oscillatory movements that contribute to the removal of sediment deposited on the partition 11 into the lower part of the device. When you exit the pipe 8, the liquid passes through a suspended layer of sludge entering the lower part of the device through the pipe 12, which contributes to additional clarification of wastewater from suspended substances. The forced withdrawal of sediment to the last part, as well as the prevention of its stagnation and decay on the partition 11, is promoted by rods 15 fixed on the bell 13 of nozzle 12. The rods 15, like the nozzle 12 attached to the partition 11 by means of flexible insert 16, make slight oscillatory movements that contributes to the transport of sediment on the partition 11 to the nozzle 12 and through it into the lower part of the device. The purified water is collected by the perforated pipe 4 and discharged through the pipe 5 from the device. The precipitate from the bottom of the device is discharged through line 6.

The application of the proposed device Construction of the Device allows for the continuous forced removal of sediment from the conical partition 11, which prevents it from sticking and rotting and promotes additional clarification of the liquid as it passes through the layer of suspended sediment. These structural differences allow to increase the efficiency of the device, in particular, increase the efficiency of wastewater treatment up to 75-78%.
