After the monitoring process of the target land mass detects the state of volatile organic pollution, the existing groundwater monitoring well can be used for repair work in a timely manner under the condition that there is no need for excavation and only a simple installation operation, the risk of construction in the service area can be effectively reduced. This can be avoided and the cost of repairs can be clearly reduced. The disadvantage of this analog is the complexity of its design, if necessary, periodic maintenance work.

Also known from the prior art is a SYSTEM AND METHOD FOR IN-SITE RECLAMATION OF GROUNDWATER POLLUTED WITH PERFLUORINED COMPOUNDS [CN114380380 (A), 2022-04-22], which discloses a system and method for perfluorinated compounds of contaminated groundwater, the system contains a plurality of groundwater water wells and ground area device a lot of water intakes are located on the wall of the groundwater well in the area below the groundwater level, in the medicine injection pipe, aeration pipe and foam extractor, which are connected to the above ground area of the device are also located in the groundwater well at the bottom of the aeration pipe is inserted below the groundwater level, the foam extraction is arranged on the surface of the groundwater is carried out in a floating way, and the collected foam is fed into the above-ground device; the invention includes a surfactant with high affinity perfluor mixture in each underground well; groundwater aeration by aeration pipe to form foam in the water groundwater level; in the floating foam extractor collects the foam, the foam is pumped into the overhead repair device to be treated into liquid, a large amount of groundwater should not be pumped, environmental disturbance is small, energy consumption is low, a large number of auxiliary facilities and material handling are saved, and the cost is greatly reduced. The disadvantage of this analog is also the complexity of its design, if necessary, periodic maintenance, as well as the need to use toxic chemicals.

The closest in technical essence to the proposed technical solution is a SYSTEM AND METHOD FOR REPAIRING CIRCULATION WELLS TO REMOVE PERFLUORINATED AND POLYFLUOROALKIL COMPOUNDS FROM GROUNDWATER [CN114604983 (A), 2022-06-10], which discloses a well repair system with circulation in place and a method removal of perfluoro- and polyfluoroalkyl compounds from groundwater, which includes the following steps: the well pipe consists of a solid pipe, an upper lattice pipe and a lower lattice pipe, with the upper lattice pipe located at the groundwater level, and the lower lattice pipe located at the lower edge of the contaminated zone groundwater; the aeration system comprises an aeration pipe, the outlet end of the aeration pipe is provided with an aeration head, and the aeration head is located in the area of the lower section of the lattice pipe; the collecting and retrieving system comprises a retrieving pipe, in which the head for collecting foam is located at the collecting end of the retrieving pipe and is located above the water surface of groundwater in the well; the separation treatment system comprises a gas-liquid separator, a gas treatment device, and a liquid phase collection tank, in which the liquid phase collection inlet is located above the surface of the water in the well. The gas-liquid separator is connected to the outlet end of the exhaust pipe, the outlet is connected to the gas treatment device, and the liquid outlet is connected to the liquid phase collection tank. The invention increases the PFAS recovery factor due to aeration treatment and integration with a well for groundwater circulation, and also reduces the cost of repair and the recovery period of groundwater contaminated with PFAS.

The technical problem of the analogs and the prototype is that these technical designs are complex and require periodic maintenance and cleaning of the aeration system components.

The objective of the invention is to eliminate the disadvantages of the prototype.

The technical result is a simplification of the technical design of the well aeration device.

The claimed technical result is achieved due to the fact that the device for aeration of the well contains a compressor, the compressor outlet is connected to the inlet of the air supply pipe, the outlet of the air supply pipe is connected to the inlet of the air aerator, an aeration elbow is mounted in the lower part of the air aerator, which can be placed in the casing pipe of the well, reversal of the air flow by 180 degrees.

Brief description of the drawings

Figure 1 shows a vertical section of a well for aeration.

Figure 2 shows the outlet pipe and the aeration knee of the installation.

Figure 3 shows the construction phase of the pool for the accumulation of aerated water.

Figure 1 indicates: 1 - well casing, 2 - water, 3 - static water level, 4 - compressor, 5 - air supply pipe, 6 - air aerator, 7 - outlet pipe, 8 - docking seal, 9 - coupler , 10 - aeration elbow.

Implementation of the utility model

The device for aeration of the well is mounted in the casing pipe of the well 1, the water 2 in which is raised to the static water level 3. The outlet of the compressor 4 is connected to the inlet of the air supply pipe 5, the outlet of which is connected to the inlet of the air aerator 6, mounted inside the casing of the well 1. Casing the well pipe 1 is mounted with the outlet pipe 7 through the joint seal 8 and the coupler 9, which is, as an option, a bolted connection. In the lower part of the air aerator 6, an aeration elbow 10 is mounted, designed to turn the air flow parallel to the direction of water 2 entering the well. In an embodiment, the aeration elbow 10 is configured to turn the flow 180 degrees.

The utility model is used as follows

Through the well casing 1, water 2 enters the well from an underground natural or, alternatively, an artificial reservoir. In this case, the water 2 must rise to the static water level 3. With the help of the compressor 4, an air flow is created, which enters the well through the air supply pipe 5 and the air aerator 6. The dispersion of air inside the well casing 1 occurs through the aeration knee 10, which turns the air flow in the direction of water flow in the well. When water 2 and air interact, water is aerated, that is, water 2 is saturated with air. Further, through the outlet pipe 7, connected to the casing pipe of the well 1 by means of a docking seal 8 and a coupler 9, aerated water enters the consumer.

The technical result - the simplification of the technical design of the well aeration device - is achieved due to the fact that the compressor 4 through the air supply pipe 5 and the air aerator 6 and the aeration elbow 10, mounted inside the casing pipe of the well 1, supplies air to the passing water, aerated water is formed, which through the outlet pipe 7 enters the consumer. Thus, the claimed device includes a small number of functional parts (on average 40-60% less than in solutions known from the prior art), which allows to achieve the claimed technical result - simplification of the technical design. Which, in turn, led to a reduction in labor costs for servicing the device - up to 40% (due to the fact that the probability of device breakdown has significantly decreased with a decrease in the number of parts used), and made it possible to operate the well without periodic maintenance.

Implementation example.

The author independently made a layout of the proposed device. In FIG. 2-3 shows the implementation of the units of the proposed device and the construction of a pool for the accumulation of aerated water. As the practice of using this device has shown, thanks to a simplified design, labor costs have significantly decreased (up to 40%) for servicing the device, and the operating time for the amount required for irrigation has decreased.
