The invention relates to hydraulic construction and can be used as a sump for water clarification in the household needs.

The famous river front intake with periodic washing [1], containing a sump with periodic flushing. The disadvantage of this technical solution are:

- the complexity of the structures due to the large number of different elements;

lack of efficiency washing sediment;

- the proposed solution is not efficient, and economical.

The closest technical solution is the tank containing the input gateway controller, a working chamber output gateway controller with a wash chamber [2]. The disadvantage of this technical solution are:

lack of efficiency washing sediment;

- relative economiccost technical solutions.

The purpose of the invention. Improving the efficiency of the clarification of the flow and efficiency of the design of the sump.

This objective is achieved in that the flow of water enters the avankamera and gradually, evenly expanded and supplied to the input gateway controller (figure 1). In the input gateway-controller is equipped with a groove for emergency repair of the shutter, and has a working shutter (figure 2). During operation of the sump working shutter. the Yu opened. Then the water enters the working chamber, the geometrical dimensions of which are designed for speed, favorable for the deposition of particles calculated fraction. Calculation of the dimensions of the working chamber are in flow flowing in the discharge channel of QKahn. The cost of one camera depends on the adopted number of cameras

,

where n is the number of the working chambers of the tank. When adopted, the average longitudinal velocity of 0.2-0.3 m/s, during the deposition of sediment, the living section of all cameras will be

For the rectangular cross section of width at a given average depth Hcfwill be

The length of the working chamber defined by the formula:

where k is a numerical coefficient, taken within 1,3-1,5; ω - hydraulic estimated size fractions of sediment subject to deposition.

As the flow stream of particles under the action of its own weight deposited in the dead volume of the working chamber. For flushing of deposited sediment after filling the dead volume on the output gateway-controller is equipped with a rinsing gallery.

After silting one of the working chambers is necessary to carry out the washing. For this work the gate on the entrance gateway controller is lowered to the desired height, working the bolt on the output gateway, the regulator is completely closed. Opens wash gallery, through which wash settled in the dead volume of sediment. To exclude flow failure during washing in the working chambers 5 are provided, which wall. The washing water flow during the flush hits on flat boards, which under the action of their own weight to press the thread to the bottom, greatly increasing erosion of sediment (figure 3). Flat panels rotate around axes which fix them to the walls of the tank (figure 4).

For weekend gateway-controller is equipped with grassroots interfacing section. The clarified water flows into the discharge channel.

The sludge consists of avancuara 1, which adjoins the entrance gateway controller 2. In the input gateway-controller 2 includes a groove 3 for emergency bolt and work the shutter 4. The water clarification occurs in the working chamber 5, which is adjacent to the output gateway controller 6 with a wash gallery 7. On the output gateway-controller 6 has a work stopper 8 and the groove 9 for emergency gate, the cat is who inserted shandori during the accident or repair. In the working chamber 5, which has a wall 10 to which is attached a flat boards 11 rotating around the axis 12. Settling of sediment occurs in the dead volume 13 of the working chamber 5. Output gateway controller 6 is adjacent to the grassroots interfacing section 14.

Sump with periodic flushing works as follows. The water flow enters the avankamera 1 and gradually, evenly expanded and supplied to the input gateway-controller 2 (figure 1). In the input gateway-controller 2 has a groove 3 for emergency repair of the shutter, and has a working shutter 4 (figure 2). During operation of the clarifier work 4 shutter is fully open. Then the water enters the working chamber 5, the geometrical dimensions of which are designed for speed, favorable for the deposition of particles calculated fraction. As the flow stream of particles under the action of its own weight deposited in the dead volume 13 of the working chamber 5. For flushing of deposited sediment after filling the dead volume 13 on the output gateway-controller 6 includes a rinsing gallery 7. Working the bolt has a groove 9 for emergency repair of the shutter, in which are inserted Sundry during repair or accident.

After silting one of the working chambers 5 it is necessary to carry out the washing. For this work the bolt 4 on the entrance gateway-controller 2 is lowered to the desired height, working the first shutter 8 in the output gateway-controller 6 is completely closed. Opens wash gallery 7, through which wash settled in the dead volume 13 sediment. To exclude flow failure during washing in the working chambers 5 are provided, which wall 10. The washing water flow during the flush hits on flat panels 11, which under the action of their own weight to press the thread to the bottom, greatly increasing erosion of sediment (figure 3). Flat panels 11 are rotated around the axis 12, which fix them to the walls of the tank (figure 4).

To enhance the process of erosion of deposited sediment in a flat boards 11 may be made of the slot (figure 5).

For weekend gateway-controller 6 has a grassroots interfacing section 14.

The proposed solution will improve the speed and quality of flushing sediment compared with the option of conventional clarifiers.

The cost of construction or reconstruction of such an option intakes minor and quickly recovered.

FIELD: water construction purification.

SUBSTANCE: invention relates to hydromechanisation namely to technology of purification and restoration of biological ponds of purification plants. Method of purification and restoration of biological ponds of purification plants includes intake of silt sediments with suction dredge from the bottom of multi-sectional pond and their transportation to sedimentation tanks. Pond is divided into two working areas of treatment, the latter is connected by means of additional input collector with sewage-water supplying canal in direction of sewage water flow motion, the former is blanked off, and construction of ground dam in area of purification is carried out as protective means. After that step-by-step purification of area is performed, for this purpose trench in silt sediments layer is sucked off by suction dredge, after that clarified water is pumped out and discharged into diversion canal. Silt sediments are collected in flowing state and transported either to silt sites or to sedimentation tanks. After that compressed silt sediments are dried by means of active ventilation and removed layer by layer as upper layer dries. After complete removal of silt sediments, base, bed of purified pond section, is restored, and said procedures are step-by-step repeated in successive purification of all sections of first area. Before purification of second working area round dam is erected again in last section of first working area of treatment, separating it from second working area, which is blanked off. First working area is joined to additional output collector with branch duct and opened, after which purification and restoration of sections of second working area are carried out. After finishing purification works ground dam, which was re-erected between two working areas, additional input and output collectors are removed, and second working area of pond is opened for functioning.

EFFECT: ensuring possibility of functioning of purification plants biological ponds without stopping them for purification.
