The aim of the invention is to increase the degree of deironing of groundwater.

The drawing shows a plant for deironing groundwater in a formation.

The installation comprises a well 1 with a casing 2 and a filter 3, a hermetic septum 4 in which an air-lift 5 is mounted with an air tube 6 and a lifting column 7, which with the help of a flange 8 rests on the casing 2 and is connected by a pipe 9 with a sealed container 10. In the latter, an overflow wall 11 is installed, dividing it into two sections 12 and 13, an air valve 14 located in the upper part of the hermetic container 10, and sensors 15 and 16 of the liquid level located in its upper and middle parts connected to shut-off valves 17 and 18 installed in the pipeline 19 for supplying water to the consumer and the pipeline 20 connecting the sealed container 10 with the casing 2 and the cylindrical anode 21i separated by a separator grid 22 with a charging cathode 23. A sensor 24 is installed above the filter 3 the water level in the squash connected to the air valve 14, the anode 21 and the cathode 23.

soluble atsod 21 and a charging cathode 23 of hydrophobic carbonaceous material provides the formation and entry of oxygen, chlorine (from the anode) and hydrogen peroxide (from the cathode) into water, which allows increasing the degree of deferrization of groundwater in the reservoir at high values. iron concentrations, including those in the form of complex compounds. 1 il.

Installation for the removal of iron in the reservoir works as follows.

In the initial position of the locking

valves 17 and 18 are closed and air valve 14 is open. Air is supplied through the air pipe 6 to the lower part of the filter, and water is extracted with its simultaneous aeration in the water-lifting column 7 and carbon dioxide is blown out of the water. This achieves an increase in the pH of the water, which contributes to the acceleration of the process of hydrolysis of ferrous and ferric iron. From the lifting column 7, water in the form of an air-in-water emulsion enters section 12 of the hermetic tank 10, where air is separated from it, which through the air valve 14

is removed to the atmosphere. As water accumulates in section 12, it enters section 13 through overflow wall 11, and the latter is filled. When the water level in section 13 rises to the mark at which the liquid level sensor 15 is installed, the shut-off valve 17 opens and the air valve 14 closes. This stops the water supply from the well 1 to the airtight container 10 and starts to squeeze water out of it pipeline 19 to the consumer. The water level in section 13 is reduced. When he gets to the mark,

on which the liquid level sensor 16 is installed, the shut-off valve 17 is closed, the shut-off valve 18 is opened, and the anode 21 and the cathode 23 under

are connected to a direct current source (not shown), this causes water to be squeezed out of section 12 through conduit 20 through the annulus between the water-lifting column 7 and casing 2 into the space between the anode 21 and separator grid 22, and then through the cathode 23 into the aquifer. When the water level in the annulus reaches the mark at which the water level sensor 24 is installed

shut off valve 18 and disconnecting the anode 21 and cathode 23 from the DC source, after which the well pumping cycle begins again.

Filter 3 equipment with an insoluble anode 21 and a cathode 23 of hydrophobic carbon material provides for the formation and entry of oxygen from chlorine (from the anode) and hydrogen from the cathode, which allows increasing the degree of deironing of groundwater in the formation at high initial concentrations x iron, including in the form of complex compounds.

ala) is due to its low catalytic activity in the reaction of decomposition of hydrogen peroxide, which is formed during the cathode reduction of oxygen. The necessary oxygen for the process enters the water and aerates it, as well as due to the decomposition of water at the insoluble anode.

The connection of fluid level sensors installed in an airtight container and in a well, with a cathode and anode provides voltage to the electrodes only when water flows through the cathode into the aquifer.
