Description

 The invention relates to the field of water treatment for industrial and domestic needs and can be used in water supply systems.

A known installation of deferrization of groundwater containing a water well with a water-lifting device and a water conduit, a pressure pipe connecting the well with a water conduit, and a pipeline for supplying water from the water conduit to the well with an aerator installed on it [1]
The main disadvantage of the known installation is weak aeration of water in the aquifer.

Closest to the invention is the installation of deferrization of groundwater in the reservoir, containing a water well with a water-lifting device, a water conduit, a water supply pipe from the well, an aerator installed in the water supply pipe to the well, regulating valves [2]
The disadvantage of this installation is that it also does not provide deep penetration of air or air-water mixture into the aquifer.

 The technical task, the invention, is to increase the productivity of the installation by increasing the volume of air and the depth of its penetration into the aquifer.

 To solve this problem, the installation of deferrization of underground water in the reservoir, containing a water well (or a group of wells) with a water-lifting device, a water conduit, a water supply pipe from the well, an aerator installed in the water supply pipe to the well, and control valves installed in the pipelines, is additionally equipped a power pump, and the water-lifting device is made in the form of a hydraulic drive pump with a hydraulic packer, the cavity of which is provided with a cavity of the working fluid supply pipe to this pump. The piping installation is made so that through the control valves, such as valves, to the input of the power pump connected to the pipeline supplying the working fluid to the hydraulic pump, water conduit and pipeline supplying water to the well.

 In FIG. 1 shows a diagram of the installation of deferrization of groundwater in the reservoir, FIG. 2 hydraulic pump with hydraulic packer.

 The underground water deferrization unit in the formation consists of a water well 1 with an airtight head 2 and a hydraulic drive, for example, a jet pump 3 equipped with a hydraulic packer 4, a water pipe 5 and a pipe 6 with a valve 7 for supplying water from a well connecting a water pipe 5 and a water well 1 through parallel connected pipelines 8 and 9 with water meters 10 and 11 and valves 12 and 13, respectively. The valve 13 on the pipe 9 is installed to the counter 11 in the direction of movement of the water. The receiving pipe 14 of the power pump 15 is connected to the pipelines 6, 8, 9, the discharge pipe 16 of which branches out into a pipe 17 with a valve 13 for supplying water to the pump 3 and to a pipe 19 with a regulating device 20 for supplying water to the pipe 9.

 A pipe 21 with a valve 22 is used to connect the aerator 23 to the pipe 17. An air inlet 24 with a non-return valve 25 is connected to the aerator. The air-air mixture from the aerator is piped 26 to the pipe 6 between the valve 7 and the head 2. To the input of the power pump 15 by the pipe 27 s the valve 28 is connected to the tank 29 with water to start the pump.

 Sealed head 2 is equipped with a pipe 30 with a control valve 31 to release excess air.

 The jet pump 3 is installed in the well on a pipe string (pipe) 32, through which the working fluid from the power pump 15 is supplied to it.

 The cavity of the packer 4 is in communication with the cavity of the pipe 32. When the working fluid is supplied through the pipe 32, the packer 4 is inflated and closes the annular gap between the pipe 32 and the well 1.

 For the first start-up, the tank 29 is filled from the water conduit 5 or with imported water. The initial position of the valves and valves is closed.

 To pump water from a water well, open the valve 28 and start the power pump 15. Open the valve 18 and water (working fluid) through the pipe 16, 17, 32 enters the jet pump 3, while the packer 4 closes the annular gap between the pipe 32 and the walls of the well . Water from reservoir 33 into the well is sucked into the jet pump. With open valves 7 and 13, water from the well through line 6 partially enters into line 14 and partially into line 9 and then into line 5. After filling the tank 29, the valve 28 is closed and water through line 14 enters the inlet of power pump 15. When the head the jet pump 3 is not enough to supply water to the conduit 5, close the valve 13 and open the regulator 20 and the water into the conduit 5 begins to flow through pipelines 19 and 9 under the pressure of the power pump 15. The pressure in the pipelines 16, 17 and 32 is determined by the diameter of the working nozzle of the jet n Sosa and regulating device 20 which is opened or closed depending on the pressure in the duct 5.

 To transfer the installation to the mode of pumping aerated water into the aquifer 33, the valves 7, 13 and 18 are closed (the regulator 20 is closed), and the valves 12 and 22 are opened. Water from the water conduit 5 through pipelines 8 and 14 enters the power pump 15, which through the open valve 22 delivers water to the aerator 23, made, for example, in the form of an ejector, the air-water mixture from the aerator through pipelines 26 and 6 is supplied under pressure to the head 2 The pressure for injecting aerated water into the well 1 is controlled by a valve 31, while the excess air is released into the atmosphere. Aerated water through the annular space, flowing around the compressed packer 4, enters the bottom of the well and is pressed into the reservoir 33. The injection volume is controlled by the counter 10.

 As a result of the application of the invention, the zone of "charging" water-bearing rocks with oxygen in the air expands significantly, creating a geochemical oxidizing environment, which ensures the purification of water to the required levels. During the selection of produced water from the periphery to the “charging” zone, iron and manganese are oxidized by adsorbed oxygen. After the reservoir is “charged", the installation is switched back to the mode of pumping water from the well.

 For the normal supply of water to consumers, it is necessary to equip at least two water wells with installations that must work in antiphase, i.e. one installation works in the "pumping" mode, and the second in the "download" mode.
