    The invention relates to the purification of water using coagulants. The purpose of the invention is to increase the cleaning efficiency. To achieve the goal, in a device for two-stage water purification in a suspended sediment layer, a distribution chamber 8 is made with nozzles 9. Means for transferring water with sediment from the first cleaning stage - cleaning chamber 3 to the second stage - condensation thickening chamber 5 is made in the form of a vertical pipe 15 with an opening 18. The coagulants are mixed with the treated water in the source water supply pipe 6, in the distribution chamber 8 and in the lower part of the vertical pipe 15. After mixing in the coagulation bath 7, the water is cleaned in the first station suspension in the suspended layer of sediment 4. Possible secondary coagulation for the consolidation of sediment flakes, and coagulant enters through conduit 27. A third dose of coagulum is supplied through conduit 28 and accelerates the flake concentration in the condensation chamber 5. The device provides uniform mixing of water with coagulants, hydrodynamic stability of the process and high quality cleaning. 3 hp f-ly, 4 ill.

    The invention relates to the field of cleaning the hearth using coagulants.
    The purpose of the invention is to improve the cleaning efficiency.
    1 shows a water purification device, a longitudinal section; figure 2 is a section in figure 1; figure 3 - partition with nozzles, longitudinal section; figure 4 - nozzle and the type of turbulence of water in this area. The device comprises a vertically mounted cylindrical body 1, divided by a transverse partition 2 into a cleaning chamber 3 in a suspension bed 4 of the sludge and a chamber 5 located under the partition of the sludge thickening. Chambers J and 5 form a water purification stage. The device contains a source water supply pipe 6, a coagulation bath 7, from which water enters the distribution chamber 8 located on the partition 2. The distribution chamber 8 has its nozzle surface 9 distributed over Bceii. In the cleaning chamber there is a circular threshold for draining the cleaned water, tray 11 and nozzle 12 for release.
    The device has a nozzle 13 with a valve and means for overflowing the suspended sediment of the cleaning chamber into the thickening chamber, made in the form of a vertical one, installed along
    housing axes, pipes 15 with upper
    edges 16 for sludge overflow, anti-swirl blades 17 and opening 18 for removing large, dense agglomerates of flakes from the bottom of the cleaning chamber 3. The lower edge of the vertical pipe 15 is located in the sludge thickening chamber 5 below the nozzle 13 to release purified water from it, but above the nozzle 19 removal

    draft. A deflector 20 is installed below the vertical pipe 15 to distribute the sludge in the sludge thickening chamber. Vertically in the housing 1 along its axis there is mounted a shaft 21 with a drive 22, scrapers 23 and 24, located respectively at the bottom cleaning the chamber for supplying large dense agglomerates of flakes to the opening 18 of the vertical pipe 15 and at the bottom of the condensation chamber 5 for supplying sludge to the socket 19 to remove it.
    The device has means for adding coagulum to the treated water, consisting of a coagulation bath 7, a multi-chamber pump 25 and pipelines 26-28 supplying coagulants respectively to the source water supply pipe 6, to the distribution chamber 8 and the lower part of the vertical pipe 15. The nozzles Y distributed over the entire surface of the distribution chamber 8 are located along the vertical axis 29, have guiding elements 30 and are connected to the cleaning chamber 3 through the opening 31.
    The device works as follows.
    Source water flows through the pipe. the wire 6 into the coagulation bath 7 with the coagulants supplied through the pipe 26. After mixing, the source water with the coagulants enters the distribution chamber 8 and through the nozzles 9 enters the cleaning chamber 3, which is the first step of cleaning. At the bottom of the cleaning chamber, as a result of primary coagulation, a suspended sediment layer 4 is formed, which flows into the lower chamber through the upper edges 16 of the vertical pipe 15 and through the opening 18. Primary coagulation provides
    the formation of small flakes less than 1-2 mm.
    Secondary coagulation takes place in distribution chamber 8. Dose of coagulum is supplied through conduit 27.
    A third dose of coagulum is supplied through line 28 to the lower
    part of the vertical pipe 15 and acceleration -10 transverse partition under the clearing
    The BT concentration of the flakes in the second stage of purification is in the sludge mixing chamber. Both stages of purification produce purified water through the pipes 12 and 13.
    In the lower part of the cleaning chamber 3 in the layer 4 of the suspended sediment, it is possible to form large dense agglomerates that are moved by scrapers 23 and flow through the opening 18 into the lower chamber 5 of the sediment thickening. After separation of the mixture in this chamber, water is removed through the nozzle 13, and the sediment is discharged through the nozzle 19. The dense sediment is moved by the scrapers 24.
    The advantage of the proposed device is the uniform distribution of the flow rate of purified water with coagulants over the cross section in the housing and the uniformity of flow rates from the nozzles into the layer of suspended sediment. Stirring water with coagulants in a coagulation bath
    and distribution chamber; turbuli-pp baths.), multi-chamber dosing of this mixture in the nozzles and the turbulence at the exit from them ensures the hydrodynamic stability of the process and high quality of cleaning.
