The present invention relates to a process for the removal of iron and / or * manganese and / or * ammonia from water to be extracted with a tentacle or a mine, and a tentacle and a mine for the process,

Tentacles and wells are widely used worldwide for drinking water. Tentacles usually have a hanging gutter trough, and tentacles with a hairy surface, which are either horizontally or almost horizontally driven out of the trough. The number of tentacles flown in the middle or two opposite directions is usually between two and twenty. Mine wells have no tentacles, only perforated or hairy wells.

Both tentacle wells and manholes can rationally produce high quality drinking water, but the problem is that the extracted water often contains impurities of iron, manganese and ammonia. These contaminants are generally introduced into the water as a result of reduction processes and can therefore be precipitated or converted by the addition of an oxidizing agent and removed from the water by filtration. Water must be treated to remove contaminants, which may be by artificial or natural filtration.

The artificial filtration operation requires cleaning equipment outside the well, which includes machinery, works of art and buildings, thus requiring high investment costs while also being expensive to operate.

For natural filtration, the filtration capacity of suitable soil is used. In the simplest case, the water to be treated is discharged directly into open-surface reservoirs / pools located in the region of the soil surface and seeks to remove contaminants with groundwater it is easy to get dirty and ultimately has the disadvantage that such a natural filtration pool requires quite a lot of space. These disadvantages are e.g. activated carbon, which in turn increases costs.

- 3 A I85 O77. Hungarian Patent No. 5,101,123 discloses a tentacle well which can be used to obtain iron and manganese-free and partially de-acidified water from the soil. The essence of this solution is that there are filtered pipes between the water-producing tentacles or their extension, through which oxygen can be supplied to the groundwater, so that the decontamination of the pollutants can be solved. The disadvantage of this solution is that the additional tentacles and tongue extensions are .

It is an object of the present invention to provide a solution for the removal of iron and / or manganese and / or ammonia from tentacle water which, without the need for a separate artificial filtration device or free-surface reservoir and the release of separate oxygen-feeding tents into the soil itself operation. It is a further object of the present invention to provide for the removal of dirt in wells in wells. In both cases, the procedure must be feasible at a low cost and in a way that ensures long-lasting operation.

The invention is based on the discovery that when the tentacles are alternately used for water production and sometimes for the transfer of oxidizing agent to groundwater, high efficiency cleaning can be carried out with minimal equipment and cost. It is a further discovery that by dropping shower troughs from the mine shaft into the aquifer to deliver the oxidizing agent to groundwater, purified water can be obtained continuously through the vertical filters of the mine shaft.

Based on these findings, the object of the present invention has been solved by a process comprising an oxygen-enriched process.

feeding water to the aquifer and from there purifying water from the tentacle, which is characterized in that the tentacles extending from the well of the tentacle in different directions are alternately fed with oxygenated water to the aquifer, and from there are purified water. Preferably, a portion of the water produced by one or more troughs, preferably about 10-50 µg, in the well or / and outside the container is preferably mixed with oxygen and this oxygen-enriched water is fed with one or more other tentacles. into the waterlogging layer.

Conventional methods of tentacle formation are appropriate, but it is preferred that the tentacles be as long as possible to increase the extent of the oxidation zone. It is advantageous to have a tentacle design in which the length of 1 / 3-1 / 2 of the tentacle is extruded with a solid tube from the collar, all the more since this inner tube section has no role in production. This, in turn, can extend the filtering area to a larger area, which increases efficiency.

During the production of water with the acacia, oxygen-enriched water is fed into the aquifer and purified water is then produced from the acacia and this process is characterized by feeding the oxygen-enriched water through the troughs out of the well through the filtered section of the well. . In this case, it is expedient to add oxygen to a portion, preferably about 10-50%, of the water produced by the acacia, thereby feeding oxygen-enriched water through the tentacles into the effluent layer.

The tentacle according to the invention has a well and a tongue projecting from the lateral drainage layer, and the essence is that there are at least two tentacles having at least two closure fittings, one of which is used to release oxygen-enriched fluid into the tentacle and and the other closure assembly is adapted to allow the passage of water from the aquifer to the well through the tentacle and to block the passage of this water. In a preferred embodiment, the well has a pump, which is preferably encapsulated, into which the connecting lines from the tentacles open and connect the connecting valves between the oxygen-enriched liquid as the source of the well and the latter. closures for closing and opening the passage of water from the aquifer through tentacles; and that a branch line containing a regulator assembly is branched from the pump line for conveying the extracted water to the consumer, preferably connected to an oxidant mixer located above the liquid space in the well. In this case, it is expedient to have a pump for conveying water from the aquifer to the consumer through a well and a pump for conveying such water from the well to an oxidant mixer in a tank, which flows from the water in the tank to the troughs, sealing fittings for opening and blocking the path of the enriched water to the tentacles are incorporated in the branch lines for blocking and unblocking the path of the water from the drainage layer

And closure fittings 6 are connected to a portion of the tentacles within the well, preferably to the end thereof, and if the tentacle has one or more tentacles directly / unloaded or substantially untreated / producing water to the pump in the well, preferably encapsulated. which pump line is connected to a line for delivering purified water to the consumer.

The present invention also relates to a tentacle having a well and tentacles extending therethrough into a lateral drainage layer, characterized in that the inner space of the well is divided into at least two compartments by a partition, preferably vertical, and one from each compartment. or a plurality of tentacles protruding, each of which is provided with a separate pump, the valves of which are provided with shut-off valves to the pipeline for conveying the water extracted; and a branch line extending over or into another space portion, preferably containing a regulator assembly, from each pump conduit to which an oxidant agitator for supplying oxygen-enriched water is connected to the other space portion.

As can be seen from the foregoing, there are several ways of delivering the oxidant through the tentacles to the aquifer and securing production separately but simultaneously at the well. In one solution, the tentacles are provided with a double - enriching and producing locking mechanism, in which, in one locking position, the oxidant is introduced and in the other, production occurs. If oxygen-enriched water is pressed back into the soil through the well, it is advisable to connect the tentacles of the tentacles for production to the suction port of the pump. If you turn the water produced

- 7 passes through the production lock and well to the pump / k, the shower water is supplied to the layer to be activated via the closed piping system and the shower locks and tents. In both cases, some of the tentacles are enriched and the remainder are productive and the functions are exchanged for continuous water treatment, the optimal execution of which requires an appropriate / known / automated command and control system.

As stated above, by dividing the interior of the well and by alternating operation of the pumps in the space and by enriching the groundwater with oxygen on the opposite side, it is possible to produce some of the tentacles with continuous production and supply oxygen to the other troughs. and the function of the tentacles is interchangeable.

If the effluent layer conditions are such that non-purifying water can be obtained, it is possible, as described above, to separate the clean and contaminated waters and treat only with the required amount of water, i.e. contaminated with iron manganese ammonia. treatment. In this case, at least two pumps operating on the mains are built into the well, one for conveying water that requires treatment and the other for non-treatment water. One of the pumps - eg. encapsulated submersible pump - directly connected by pipeline to one of a kind of water-quality water supply troughs, while the other pump transmits water from tentacles connected to the well. Water treatment can be carried out according to any solution. It is preferred that tentacles producing water that does not require water treatment e.g. they are directly connected to the encapsulated pump via a pipeline, while some of the tails supplying water loaded with iron or / and manganese or / and ammonia are fed to the oxygen-enriched water

- 8, but with the other tentacles, pumped water is produced through the water of the well, rain functions are interchanged periodically. The most preferred way of oxygen enrichment is to saturate a portion of the water produced with oxygen and then return this water to the tentacles through a duct and a lock. Generally, 10-50% of the water produced is used for oxygen delivery.

The mine shaft of the present invention has a well shaft and pump with a filtered section, and the shaft well is characterized by having troughs extending laterally from the well to the drainage layer above the filtered section; a branch line from the pump line or from the line connecting the extracted water to the consumer, preferably having a regulating means, to which an oxidant mixer in a reservoir is connected, a line out of which is connected to the tentacles , in which closure fittings are preferably incorporated. What has already been said about tentacle designation also applies to acacia shower tentacles,

The invention will now be described in more detail with reference to the accompanying drawings, which include some preferred embodiments of the tentacle and a preferred one. 1 is a schematic vertical sectional view of a preferred embodiment of the tentacle according to the invention;

Schematic vertical sectional view of a mining well constructed in accordance with the present invention.

The tentacle shown in Fig. 1 has a well 1 which is lowered to the f level of the watertight layer 15 below the water layer, i.e. to the fect. At one or more levels of the lower region of the well 1, tentacles 2, 3 are driven in a circular or opposite direction to the drainage layer 16, e.g. sandy pebbles. The number of tentacles per mine can range from two to twenty, two of which are shown in Figure 1.

Connecting wires 8a, 8b are connected to tentacles 2 and 3 within well 1, into which closures 5 and 7 are incorporated. Between the closures 5 and 7 and the well wall each

A 51.52 nipple extends into the connecting line 8a and 8b. The fitting 51 is provided with 4 fittings and the fitting 52 with 6 fittings. The connecting lines 8a, 8b extend into the housing of the pump housing 9 which is centrally located inside the well 1. A branch line 53 containing a regulator assembly 11, which is connected to the pump 9, flows into the oxidant mixer 12, which is preferably an air or oxygen mixing device based on an injector principle.

The tentacle shown in Fig. 2 differs from that of Fig. 1 primarily in the number of pumps and in the positioning of the oxidizing agent mixer, therefore, the components already described are denoted by the reference numerals already used. In this embodiment, the closure fittings 4, 5 and 6, 7 are connected to the lower and upper ends of the tongues 2, 3 within the well. Line 10 of pump 9 is led out of well 1 below ground level t and line 10a of second pump 80 flows into oxidant mixer 12 located above ground level in upper part of container 14 located outside well 1 a conduit 17 extends from the lower portion of the container to the liquid space, from which the branch conduits 17a, 17b are branched. These are connected to the closing fittings 4, 6 of the tentacles 2, 3 (there are, of course, as many branch tines as the tentacles, but only two tentacles can be seen in Figure 2).

The embodiment of Figures 3 and 4 differs in particular from that of Fig. 2 in that it has three pumps. Only three tentacles 2, 3 and 19 are shown in the tentacle, tentacle 19 extends directly into the housing of the encapsulated pump 20, and its line 54 is connected to line 10, in the same way as line 55 of pump 9, is located in the lower part of the well, in the water space of the well, as is the pump 80, whose line 10a is in turn connected to the oxidant mixer 12 in the upper part of the tank. it has a downwardly extending tongue 17a, 17b which has tongues 2, 3 .. which are not connected to the pump 20.

In the exemplary embodiment of Figure 5, the fluid space in the wellhead of the tentacle is divided into two compartments I, II by the vertical partition kO. The kO partition starts from the bottom level f but does not reach the top of the well. The pump 8 is located in space I and pump 9 in space II. The lines 56 and 57 for the pumps 8 and 9 end up in the network 10. Prior to the insertion point, a sealing fitting 50 is provided in the conduit 56 and a sealing fitting 60 in the conduit 57. The conduit 56 exits a 5θ branch conduit underneath the closure assembly 5θ, which terminates with a 7θ oxidant mixer. From branch 57, branch branch 59 terminates, into which a regulator assembly 14θ is inserted and at the end of which an oxidant mixer 12 is connected. Both the latter and the 7θ oxidant mixer are located above and around the upper end of the bulkhead 40. In Figure 5, reference numbers and symbols used previously, as appropriate,

The manhole shown in Figure 6 has a reference well 100 which has a filtered section 30 having a drainage port numbered 61, a well 41 having a pump 41 connected to the mains 42, A branch line 62 comprising a regulator assembly is branched to an end coupled with an oxidant mixer 44. The latter is located in the reservoir 45, just above this liquid space, out of the lower portion / liquid space 47 of the reservoir 45, from which downwardly extending branch lines 47a, 47b,. Each

47a, 47b ... branch line is connected to the inner end of a tentacle Il8, 9 ... 9 inside the mine well. Close fittings 110, 111 ... are installed in the branch lines 47a, 7b ... near the junction.

The tentacle shown in Figure 1 is operated as follows:

there is water oxygenated water 13, which is fed through the open closure 4 and the trough (s) 2 into the aquifer 16 surrounding the tap water, thereby activating the water level therein. . Activation results in the decomposition of iron or / and manganese or / and ammonia in the groundwater. The closure assembly 5 is then closed. Meanwhile, water is purified from the right region of the drainage layer 16, previously activated via the tentacle (s) 3, through the tentacles (3) and pumped through the connecting line (8b) with the closure assembly 7 open and the closure assembly 6 closed. in the pump line 10 / discharge pipe line,

About 10-50% of the water produced by the pump 9 is fed through the branch line 53 with the regulator assembly 11 to the oxidant mixer 12 where this amount of water is saturated with oxygen and supplied to the well space of the well 1 where it is degassed. As already mentioned, this oxygen-enriched water 13 passes through the tongue 2 into the left region of the aquifer,

90-50 Λ of the water produced by the tentacle 3 enters the grid via line 10. The flow directions are shown in Fig. 1 by arrows.

In the mode of Figure 1, the tentacle 3 functions as a production tent and the tentacle 2 functions as a shower tent. By opening the socket assemblies 7 and 4, the function of the tentacles 2 and 3 is reversed. By repeating this change of function periodically, the production of purified water can be made continuous. The plant - automated control of the opening and closing of the shut-off valves - combined with the detection of dirt or oxygen content - can be automated,

The tentacle of Fig. 2 has the same function as the tentacle of Fig. 1 when groundwater is flowing through tentacle 2 and purified water is produced through tentacle 3 and after a certain period of time the function of these tentacles is reversed. The difference is that the oxygen-enriched water 13 is received not by the well 1 itself, but by the tank 14, from which the pipeline 17 and the branch pipelines 17a, 17b reach alternately one or the other tentacles 2, 3. Maintaining the level of oxygen-enriched water 13 in the tank 14, which is required to ensure stable hydraulic conditions, is achieved by automatically controlling the operation / opening-closing rate / closing rate of the shut-off valve 4 and 6, respectively. the water 18 already treated in the drainage layer 16 through the open sealing vessel blood 7 in the previous process step / the sealing valve 6 is then closed / entering the well 1, where the water level is denoted by the reference letter. From here, the treated water 18 is fed to the grid or other application via pump 9 via pipeline 10. 10-50% of the treated water 18 is supplied by pump 8 to oxidant 12 in tank 14 via pipeline 10a. , from which the oxygen-enriched 13 water enters the tank water where it gasifies. From here, the water 13 flows through branch line 17a - the 4 shut-off valves are open,

With the closure assembly 14 and the closure assembly 5 closed, through the tongue 2 into the drainage layer 16. Thus, the tentacle 2 functions as a shower tent and the tentacle 3 acts as a production tent and, as already described in connection with Fig. 1, the production of purified water can be made continuous by interchanging the functions of the tentacles periodically. The water flow! the directions are indicated by the arrows for the tentacle 2 function, the tentacle function 3 is loaded.

The tentacle well of Figures 3 and h may be used in particular when the tentacles extend into layers or layers of water of different quality; some tentacles are contaminated with iron, others manganese or ammonia, and other tentacles provide clean water. For simplicity, only three tentacles 2, 3 and 9 are shown. Compared to the embodiment of Figure 2, the difference in operation is essentially that the tent 19 supplying the appropriate quality water is connected directly to the encapsulated pump 20 so that the extracted water is fed to the mains 10 via its line 54. At the same time, a portion of the treated water 18 produced by the tentacles 2 and 3 is pumped through the pump 9, while 10-50% of the treated water is supplied via line 10a and oxidant mixer 12 to the container 14 as described in FIG. enriched water alternately enters the tentacles 2 and 3.

The tentacle of Fig. 5 is operated by alternately operating the pumps 8 and 9. Both pumps are connected to a network of 10 wires. In the operating phase shown in Fig. 5, the pump 8 operates and the tentacle 2 produces water from the drainage layer 16. This treated water 18 enters the conduit 10 through conduit 56 and through an open closure assembly 5θ. Then 60

the shut-off valve is closed and the pump 9 is stopped. The water pumped by the 8 pumps is 10-50? ^z h at 11 the control valve 58 and pipe stub 70 to the oxidant sparge, and from there the water is enriched with oxygen 13 of the one-end portion II wells. Because h is the difference in height of the water column, νθ,

even between water levels, the oxygen-enriched water 13 passes through the tongue, which acts as a shower trough, into the area of the aquifer 16 to the right of well 1 and activates the groundwater there. After a defined / preferably automatically controlled / period, the

The function of the space compartments I and TI, and consequently the tentacles 2 and 3, is reversed: the tentacle 9 produces clean water, some of which through the regulator assembly 140 and the oxidant mixer 12 into the compartment I and thence through the tentacle 2 into the compartment 16. it gets into a watering layer,

The minesweeper shown in Figure 6 is operated as follows, through the filtered section 30 of the well 100, the water flowing into the well is pumped by the pump 41 and fed through line 42 to a line 10 or other outlet. 10-50 'of the water produced passes through the conduit 62 containing the regulator assembly 43 to the oxidant mixer 44 in the tank 45 and from there to the water in the tank. From here, oxygen-enriched water 46 is fed alternately to the tentacles 48 and 49 through line 47 and branch lines 47a, 47b. Which tentacle works is 110 and

111 of its closure fittings are, of course, open.

the difference in water column height h between the water levels is also the cause of the water outflow through the troughs 48, 49, which in this example have only a shower function. Oxygen-enriched water 46 in the tank 45 is v.

to maintain the level of • * · «♦

To achieve stable hydraulic conditions 16, it is achieved by automatically adjusting the closing fittings 110, 111.

An advantage of the invention is that it allows the purification of water provided by the aquifer in the vicinity of the well from iron and / or manganese and / or ammonia within the well itself, while maintaining the continuous production of the well without the use of external auxiliary water . In the case of tentacles, there is no need to install enrichment wells, or separate shower tents or shower tent sections, as the tentacles are locked or the interior of the well is separated by the tentacles to produce water and oxygenate the water in time. With this solution, compared to a conventional well, the additional cost of removing contaminants is, in the simplest case, merely the installation and control of the locking devices on the tentacles; saturating a portion of the water produced with oxygen; as well as from the drainage of this water into the tentacles. For manholes, instead of shower wells, water treatment can be achieved by driving shower troughs over the filtered well, and the additional cost of this tent opening is virtually negligible compared to a separate manhole,

The invention is, of course, not limited to the examples detailed above with reference to the figures, but may be practiced in many ways within the scope defined by the claims.
