The invention relates to hydraulic engineering, and in particular to structures for integrated treatment of water drawn from and part of the suspended sediments in water in channels, pipes and avancuara pumping stations.

Known fish protection device, comprising a cylindrical cross-section view camera with outlet conduit, in which a concentric set of annular wall with a mesh top, the inlet conduit is placed tangent to the inner surface of the wall, and rebooted connected to the center of the camera, and the protection of the annular wall has a polygonal shape, arranged alternately formed and spiral sections (USSR Author's certificate No. 1011775, CL E02B 8/02, 1980).

The disadvantages of the known devices include: education in the areas of the coupling 4 and a spiral 5 sections of the wall 3 congestive neprobivaemy sites for the accumulation of impurities, where possible sediment impairing the operation of the device; the trauma of the collision and contact with mechanical impurities and debris - juvenile fish in the direction of the Central hole in the bottom of the camera 1 and the transportation of it rebooted 7; nepredusmotritelnost permanent or periodic cleaning of the upper reticular part of the annular wall 3; constant energy costs for removal of juvenile fish back in vodosek the IR.

Closest to the proposed assignment, the technical essence and the achieved result is a tank that includes employee to collect sediment reception settling chamber having an inclined bottom wall with a window in the lower part, which divides the chamber into two sections and discharge manifold (USSR Author's certificate No. 1350242, CL E02B 8/02, 1985).

The disadvantages of the known device: periodic water supply to consumers downstream pipe 15, which is periodically interrupted during the rinse sump through the use of rising 7 and descending 9 branches of the siphon 8. As a result, the piping with clean water creates air pockets that reduce the efficiency of the known device and thereby interfere with water supply; obstruction of the outlet of the ascending branch 7 trap 8 accumulated sediment in the conical part of the tank near the window 5 and the natural mud, which could prevent the inclusion in the work of the siphon 8 (first) and lead to failure of the suction effort of the siphon 8 to raise the superficial mass of the entire height of the ascending branch 7 siphon 8, i.e. the height from the inlet of the siphon 8 up to the hood 10.

Also known, for example, hydrocyclones and packageview copyright certificates of the USSR№184187, 367895, 544473, 816558, 823647, 882942, 886998, 1065525, 13330254, 1392188, 1456234, 1546547.

On the however, the known device is complicated, due to numerous elements, not practical to manufacture, which does not allow for reliable continuous operation of the devices during their operation.

The purpose of the invention is improving the efficiency of the continuous purification of water from the bottom and suspended sediments.

This goal is achieved by the fact that in water purification facility, including serving for collecting sediment reception settling chamber having an inclined bottom wall with a window in the lower part, which divides the chamber into two sections and discharge manifold, settling receiving chamber width, which is equipped with a wall mounted height relative to each other with an offset against the wall, pinned by the second section of the chamber, the bottom of which partition is made T-shaped wall in the form of threshold and has the additional width of the settling chamber with the outlet conduit, and canopy wall mounted horizontally on its grounds one end to the side walls and the other for settling chamber.

In addition, the partition wall side section of the chamber is provided with a curved visor at the top and has a slot above the visor.

With the aim of increasing the effectiveness of regulation by reducing inputs of suspended sediment is additional settling chamber, from the outlet conduit installed vertical wall with vertical and horizontal movement perpendicular to the threshold of movement.

Moreover, in the lower parts of the bottom of the settling chamber positioned weekend leaching holes.

The bottom additional settling chamber is tilted in the direction of the flushing holes made in the pit camera, coinciding with the elevation of the bottom of the second section of the chamber.

This interrelation and interdependence of the main elements of the water treatment plant will allow the stream enriched sediments, due to the fact that sand, gravel and suspended sediment are routed first to the admissions settling chamber with a wall and go in the washing hole through the influence of the T-shaped wall with a horizontal visor and which horizontal walls at the height of the second section of the camera, also absorb the kinetic energy of the flow. In addition, the presence of additional settling chamber with a reverse bias towards washing her holes with a vertical wall that is installed with the possibility of vertical and horizontal movement perpendicular to the threshold of movement, forms a front vertical wall of the main reception settling chamber back pressure when water flows in the tailrace, over the spine of the water calms down, the velocity distribution of flow across the width of the settling tank can take a uniform, and loads quickly fall to the bottom of both cameras and have no interest in the tailrace and then to the consumer. Thus, the quality of the treated water due to the effect of calming the waters in the areas between the walls of the primary and secondary chambers. Compared with the prototype of the proposed water intake sewage-treatment plants operating in the mode of continuous supply of clarified water to the consumer. The economic efficiency of the proposed construction is to combine in a single technological cycle of optimal water intake and effective two-step purification of water from sediment.

The drawing shows a water purification facility, General view.

Water purification facility includes a reception settling chamber 1 and additional settling chamber 2 between the inlet 3 and outlet 4 parts of the conduit. The main reception sucky camera 1 for collecting sediment with an inclined bottom provided with a partition wall 5, which divides it into two sections 6 and 7, associated with window 8, is made in the lower part of the partition 5, and has a washing hole 9 with the reservoir 10. Which the device 11 is designed as horizontal walls, installed height relative to each other with an offset to the partition 5 (walls can manufactured the join of any material and can change the angle of inclination, blocking the gaps between the walls through the hinge with the help of traction, not shown). At this section of wall, which device is fixed on the outer side of the second section 7 of the chamber and the inner side of the fixed curved visor 12, above it in the partition wall 5 is made a slot 13. Vertical T-shaped wall 14 with a horizontal visor 15, one end of which is directed to the side walls 5, and the other in the direction of the camera 2, is located behind the partition 5, and secured to the bottom of the sump 16, 20. The wall 17 is located at the threshold 18 and the outlet conduit 4.

Vertical T-shaped wall 14 and the threshold 18 form an additional settling chamber 2, an area of calm water conditions. Vertical wall 17 is installed in parallel with the threshold 18 with the possibility of vertical and horizontal movement perpendicular to the threshold of the 18th move. Position 19 marked the channel between the door and the wall 17. The bottom of the additional settling chamber 2 is made to slope toward the sump 20, the walls of which are arranged at an angle α1=45-60°, and the bottom of the settling chamber is attached to the slope α2not less than 0.05, which is caused by the presence of the pit 20 and the bottom of the pit 20 coincides with the elevation of the bottom of the second section 7 of the camera.

Water purification facility works as follows.

Water along with sediment from p is dodamage section of the conduit 3 is supplied in section 6, fills in section 7, and sediment focusing in the flushing holes 9 and moved into the collector 10, and the main water flows through cracks, which device 11, slot 13 and the T-shaped wall 14 in additional settling chamber 2. As a result of flow and backwater from the side of the movable wall 17 at the threshold 18 and the outlet conduit 4 is an ascent of water, which allows larger and smaller sediment to settle to the bottom of the camera closer to nanospray holes 9 and 21, respectively, to the collectors 10 and 22, and also due to the energy flow and slope towards the flushing holes, carrying with it the restoration of the velocity distribution of the flow across the width of the additional settling chamber 2 is uniform, i.e. the steady-state mode. This effectively can affect the deposition of sand and gravel before the T-shaped wall 14 section 7, and in the sump 20 of the camera 2. Settled more fine sediment in additional settling chamber 2 are shifted by an inclined bottom side of the pit 20 leaching holes 21. Purified water passes into the channel 19 between the wall 17 and the threshold of 18 from which the downstream conduit 4 clean water flows to the consumer. To more accurately achieve the desired mode wall 17 is moved in the vertical direction, and the wall can be removed or closer to then the se (in the drawing shown by the dotted line).

It should be noted that a large number of technological methods of calculation of the settling chambers and asked for this calculation formulas progressive are the only ones that allow you to fully take into account the actual conditions of deposition and the relationship between the main design parameters. This requirement satisfies the proposal of the invention, necessary to obtain the desired positive effect nanotransporters flows, and the rate of deposition of those particles, which must be retained in the settling chambers with their constant washing. In General, this relationship is expressed by the famous equation T=N/(u0- ω), where T is the duration of sedimentation; N - adopted by the working depth of the flow part of the sump; u0- the lowest deposition rate hold particles in water that is at rest; ω - extension resistance experienced by particle settling by the movement of water in the treatment chamber. If in the primary settling chamber, divided into two sections, received relatively high speed movement of the water, while the T-shaped wall in additional settling chamber 2, the average speed is typically less than 0.01 m/s, although it may cause some indicators between estimated and actual in the structure, depending on the actual conditions the process of defending such threads but due to the constraints of elements forming a labyrinth of walls and overlap the working level, and if necessary can be adjusted, there is a back bottom currents flow at the threshold of the discharge conduit 4 decreases the surface movement of treated water to consumers, improving the hydraulic conditions of the discharge conduit 4 to the consumer. Therefore, to improve the hydrodynamic conditions of the proposed invention, the set design of the water treatment plant intake nanosensing flow and release the clarified water to the consumer. When these conditions result in the release of sediment with high concentrations of suspended sediments, and their re-deposition roiled sediment is much faster and better than in the known device.

In addition, the re-deposition of suspended fine sediment is partially in front of the T-shaped wall, and the other part in additional settling chamber 2 with the sump 20.

When properly selected ratio between the parameters of the proposed elements of the facilities provided the quality of the purified water to the consumer, depending on the hydraulic load in each partition structures. The invention is essentially a two-step clean-up of sediment that can remove loose sediment at the settlement of annoy their leaching from the two pits.

Due to consistent action all deposits are concentrated in the zone of leaching holes 9 and 21 cameras in the future fond of the collector 10 and 22, and settling chambers are exempt from sediment and prevents siltation and clogging them settling chambers.

The proximity of the forms of each pit 16 and 20 and the trajectory of the particles sediment to the T-shaped wall 14 and the opposite slope of the bottom of chamber 2 increases the influence of the suction effect to proryvnym holes 9 and 21, and the treated water through the lower edge of the movable wall 17 is fed into the channel 19 and further to the discharge conduit 4.

The cost effectiveness of applying the proposed water treatment plant is to combine in one technological cycle of optimal water intake and effective two-step purification of water from sediment.
