Hereinafter, the present invention will be described in detail.

1 is a schematic view showing a purifier according to the present invention, Figure 2 is an enlarged view showing a sump of the purifier system according to the present invention, Figure 3 shows a purification step of the purifier according to the present invention It is a flow chart.

First, the raw water inlet 100 of the purification apparatus according to the present invention may include a first raw water inlet 100a and a second raw water inlet 100b. The first raw water inlet 100a receives first raw water and the second raw water inlet 100b introduces second raw water, wherein the first raw water is excellent and the second raw water is rivers, lakes, It may be a reserve water, such as a pond, flood index.

As described above, in the present invention, in the rain, the first raw water may be collected and purified by the first raw water inflow unit, and in the case of dry water, the second raw water may be selectively taken in and purified by the second raw water inflow unit. The purification process through the one source water inlet is as follows. Hereinafter, for convenience of description, the first source water will be described as being excellent, but the present invention restricts the type of the first source water. It is not.

The first raw water inlet 100a may include a rainwater collecting conduit 10, a screen filter 20, an initial rainwater rejection system 30, and the like.

Rainwater flowing along the road surface in rainy weather, even if the clean water quality flows along the sewage pipe is mixed with sewage with a large concentration of sewage, which is introduced into the river or river, which leads to waste of water resources, install rainwater collection pipe (10) Can collect wasted rainwater.

In general, rainwater may be collected from the unpaved road, muddy water quality, and the rainwater may be collected on a relatively clean road, such as a pavement or a roof of a building, and stored in a rainwater reservoir along the rainwater collection pipe.

The present invention is a device for purifying and recycling raw water with high quality water that can be used for drinking, and in particular, the purified raw water is introduced into the groundwater wells and flows along the connected ground veins to flow into the aquifers serving as the surrounding groundwater and underground reservoirs. In order to help the circulation of water by cultivating the groundwater level, to form a pipeline in a place having a relatively large area, such as farmland, parks, playgrounds, etc. in order to achieve a relatively large amount of purification can be collected in the sump tank 40 to be described later It is desirable to.

Rainwater collected in the rainwater collecting pipe 10 as described above may be filtered through the screen filter 20.

In the present invention, the screen filter 20 may be formed in a network structure so as to physically remove relatively large particles such as fallen leaves and branches contained in the rainwater collected in the rainwater collection pipe (10), the screen By first removing the contaminants introduced into the rainwater through the filter 20, it is possible to prevent the blockage of the pipe through which the rainwater flows, thereby increasing the efficiency of the purification process performed thereafter.

In the exemplary embodiment of the present invention, a 300-micron stainless steel net is included in a hexagonal stainless steel box having an opening in which rainwater is collected, but the shape of the screen filter is not limited thereto.

Rainwater from which the contaminants of relatively large particles are removed through the screen filter 20 may be collected in the sump 40 or may be discharged.

However, rainwater that is collected early in rainy weather is not suitable for recycling because it contains pollutants in the air and has high acidity.

Therefore, it is preferable to discharge the water without storing it in the water collecting tank 40. In the present invention, the initial excellent draining system 30 discharges a certain amount of initial rainwater to the outside by the digital F / M system, and then the water collecting tank 40 is discharged. Can be collected.

The storm pipe passing through the screen filter 20 is divided into two storm pipes by the initial storm water rejection system 30, and a lock device such as a valve is formed at a certain point of each storm pipe, and the valve is an initial storm water drainage system ( 30) can be operated by receiving the digital F / M signal.

At this time, the two rain pipes bisected from the initial excellent exclusion system 30 is configured to include a water collecting guide pipe connected to the water collecting tank 40, and a separate drain pipe discharged to the outside of the water collecting tank (40).

In the early rainy weather by the initial excellent exclusion system 30 of the present invention, the valve of the water collecting induction pipe introduced into the water collecting tank 40 is closed and the valve of the drain pipe discharged to the outside of the water collecting tank 40 is opened so that rainwater is discharged to the outside. .

On the contrary, if a certain amount of time passes and the amount of rainwater discharged by the flow meter of the initial rainwater rejection system 30 is discharged or the acidity of rainwater falls below a predetermined value by acidity measurement, the inside of the sump 40 by a digital signal Since the water induction pipe valve introduced into the opening and the drain pipe valve discharged to the outside of the water collection tank 40 is closed, the discharge of rainwater is stopped, and rainwater can be introduced into the water collection tank 40 thereafter.

After discharge of the initial rainwater containing contaminants or high acidity as described above, even better water quality may be introduced or stored in the sump 40 buried in the ground or underground.

Next, the raw water that has undergone the raw water inflow step such as the rainwater collecting pipe line 10, the screen filter 20, the initial excellent exclusion system 30, and the like is filtered and purified through the purified water treatment unit 200 which is a full-scale water purification step. Can be processed.

The water treatment unit 200 of the present invention is a water collection tank 40, automatic chlorine injector 50, disk filtration device 60, activated carbon filtration device 80, ultraviolet water flow sterilizer 80, reverse osmosis water purification device (90) ), And the like.

Referring to FIG. 2, the water collecting tank according to the present invention includes a raw water inlet 41, a overflow water outlet 42, a diffuser 43, a separator plate 44, an air diffuser 45, an air pipe 47, and a blower 48. ), A level switch 49, and the like, and the raw water inlet 41 may include a rainwater inlet 41a and a reserve water inlet 41b.

As described above, the raw water passing through the rainwater collecting pipe line 10 and the screen filter 20 is introduced into the water collecting tank 40 along the water collecting induction pipe, wherein the raw water inlet 41 of the water collecting tank is the upper portion of the water collecting tank 40. Or located on the side adjacent to the top, the raw water inlet pipe 46 connected to the raw water inlet 41 is connected to the pipe so as to be adjacent to the bottom of the sump (40).

Next, the end of the raw water inlet pipe 46 piped to the adjacent region of the bottom of the water collecting tank 40 may have a curved shape in the U-shape to face the upper portion, the pipe line toward the end of the raw water inlet pipe 46 Is designed to gradually expand the rainwater flowing along the raw water inlet pipe 46 may be sprayed into the sump 40 to increase the pressure.

In addition, it is preferable to install a diffuser 43 at the end of the raw water inlet pipe 46, so that the raw water passing through the diffuser 43 can be sprayed in the lower direction rather than the upper direction of the collecting tank 40. .

This, the rainwater introduced into the water collection tank 40 along the raw water inlet pipe 46 may include a contaminant and mud not filtered by the screen filter 20 described above, the bottom of the collecting tank 40 There is an effect of sinking by spraying in the down direction of the sump (40).

In addition, a partition plate 44 in the form of a partition to settle the relatively large particles contained in the rainwater at a predetermined height from the bottom of the sump 40 at a distance adjacent to the diffuser 43 and not to be dispersed. In this case, when foreign matters contained in rainwater introduced into the sump 40 are deposited in a predetermined area, it is possible to selectively purify the sump, thereby increasing the efficiency of the sump 40 filtration device.

On the other hand, when the flow rate in the sump (40) is saturated, it is located on the side adjacent to the top of the sump, so that the overflow water drain port 42 at a position slightly lower than the raw water inlet (41) to saturate the flow rate of the sump Can drain to the outside.

However, the location of the raw water inlet 41 and the monthly water inlet 42 is not limited to the above embodiment, which is because the height of the raw water inlet 41 is higher than that of the monthly water inlet 42 so that the flow rate in the water collecting tank 40 is increased. It can be understood that when saturated, to facilitate drainage.

Next, an air diffuser 45 for purifying rainwater introduced into the water collecting tank may be included in a predetermined region under the water collecting tank 40.

The air diffuser 45 may be located in a predetermined region below the opposite sump 40 where sediments introduced together with rainwater accumulate in the sump 40 based on the separator plate 44.

In this case, the air diffuser 45 is a device that receives the air generated through the blower 48, which is an air generating device through the air pipe 47, and discharges it into the micro bubbles, air generated in the air diffuser 45 Bubbles evaporate or purify the volatile organic compounds, BOD, COD, etc. dissolved in the collection tank 40 together with the bubbles.

On the other hand, it may include a level switch 49 to measure the flow rate in the sump 40 to operate the air diffuser 45 efficiently in the appropriate level range, the user through the level switch 49 It is possible to specify the low and high levels of operation of (45). However, the present invention is not limited to the presence or absence of a level switch, and the air diffuser 45 may not only be operated according to a specified level of the level switch. Alternatively, the air diffuser 45 may be operated at all times during the purification process.

Subsequently, the water filtered in the sump 40 may be filtered through the disk filtration device 60.

When the raw water is collected, the disk filtration device 60 may introduce not only inorganic materials such as sand or mud but also organic materials such as microorganisms. This has the effect of having a semi-permanent filter life.

Disc filtration device 60 of the present invention is to perform the automatic backwash by the differential pressure and to remove the insoluble suspended solids up to 55 microns, so that foreign matters in the water does not settle or adhere to the filtration devices, the role of the filtration device At the same time there is an effect to extend the life of the filter devices connected to the disk filter device (60).

In the embodiment of the present invention, the water introduced into the disk filtration device 60 flows along the water pipe in the disk filtration device is filtered through the disk filter, and then discharged to the outlet of the disk filtration device.

In this case, a plurality of conduits are formed at the periphery of the flow pipe, and the conduits are connected to a plurality of disk-shaped filters spaced apart at regular intervals along the periphery of the flow pipe, and the water passing through the flow pipe is a disk filter. After being filtered in, it may be discharged to the outside of the disk filtration device 60 through the outlet.

In addition, the outflow pipe of the disk filtration device 60 includes a separate drain pipe connected to the flow pipe and a backwash valve for controlling the drain pipe in order to discharge foreign substances filtered by the disk filter to the outside of the disk filtration device 60. It may include.

The foreign matter filtered by the disk filter of the disk filtration device 60 remains in the disk filter, and as it accumulates, the filtration efficiency of the filter gradually decreases. At this time, when the backwash valve of the drain pipe is opened, the foreign matter attached to the disk filter is disk filtered. Together with some of the water that was in the device 60 is discharged to the outside through the drain pipe.

As a result, the disk filtration device 60 does not need to stop the filtration operation to clean the disk filter, and thus the performance of the filter is continuously maintained, thereby increasing the efficiency of the filtration operation.

Next, the water purified through the disk filtration device 60 may be purified through the activated carbon filtration device 70.

As described above, the chlorine introduced in order to prevent the water from decaying in the collection tank 40 during the dry season may be damaged by the chlorine while passing through the collecting tank 40 and passing through another filtration device, which is harmful to the human body, causing chlorine There is a need to go through chlorine removal as it is not suitable for use as drinking water while remaining.

To this end, it is possible to remove chlorine remaining in the water through the activated carbon filter 70 of the present invention.

Activated carbon is a porous carbonaceous material, which is made by treating carbon materials such as wood with chemicals such as zinc chloride or phosphoric acid as activators, and drying or firing them. Suitable for

The activated carbon filtration device 70 of the present invention removes not only chlorine contained in the water, but also effectively removes various organic substances or condensates that are filtered through the above-described disk filtration device 60 and are physically adsorbed to the activated carbon. It can be, and also has the effect of removing the various odor causing ingredients.

Next, the water filtered through the activated carbon filtration device 70 may sterilize bacteria, viruses, and bacteria present in the water by passing the ultraviolet water flow sterilizer 80, and the filtered water may be filtered through the oil and water sterilizer 80. Water can remove various heavy metal components contained in the water by passing through the reverse osmosis water purification device (90).

Reverse osmosis water purification apparatus 90 of the present invention is a device to remove not only impurities introduced into raw water, but also to remove various heavy metal components contained in industrial and agricultural wastewater, such as 95% or more to filter the water of drinking water quality.

Thus, the raw water filtered in accordance with the filtration device of the present invention can be utilized as purified water of good quality, in the present invention, by de-injecting the purified water by developing the underground well located around the water purification device, depleted groundwater area It can also prevent ground subsidence and soil disintegration, contributing to the restoration of groundwater and raising groundwater levels.

That is, the water discharged through the reverse osmosis water purification device 90, which is the final stage of the purification device according to the present invention, may be introduced into the groundwater input well 400 through a piping facility.

To this end, it is possible to connect the purified water from the filtration device of the present invention to the groundwater wells of areas already developed and depleted, or the groundwater is insufficient, or to explore new groundwater wells by exploring the underground veins of the surrounding area. It is also possible to add developed purified water. This will be described later.

By the above-mentioned method, in rainy weather, it collects a 1st raw water, specifically rainwater, and puts it into a collection tank through a 1st raw water inflow part, and can purify it.

On the other hand, the condition that the first raw water through the first raw water inlet, for example, there is a problem that the purification device is stopped due to the lack of the amount of raw water that can be purified during the dry season.

In this case, not only the operation efficiency as the purification device is lowered, but also as a larger problem, there is a problem that the life of the purification device is shortened.

That is, in the period of the dry period, the operation of the purifier as described above is also stopped, there is a problem that can reduce the life of the device by contamination of bacteria, such as breeding in each filtration device, in particular, such as summer If the temperature is high, the risk of bacterial growth is much greater.

To this end, in the present invention, even in the dry season, by operating the filtration device by introducing the reserve water into the sump (40), the operation of the purification device is continued, thereby increasing the operating efficiency as the purification device, and the purification device is continuously operated. Therefore, there is no fear of bacterial propagation.

More specifically, in the present invention, during the dry season, the second raw water may be selectively taken in and purified by the second raw water inflow unit.

In this case, the second raw water may be a reserve water such as a river, a lake, a pond, a flood index, etc., but the type of the reserve water is not limited in the present invention.

That is, referring to the embodiment of FIGS. 1 and 2, the preliminary water taken from the preliminary water source may be connected along the pipe by the operation of the pump to flow into the preliminary water inlet 41b of the sump 40. Although omitted in 1, it may be configured by additionally connecting a filtration device such as a screen filter as in the configuration of the first raw water inlet 100a.

On the other hand, the second raw water, that is, the reserve water introduced into the sump tank from the preliminary water inlet can be purified by the same method as the first raw water, that is, rainwater described above, and therefore, for the purification of the second raw water below It will be omitted.

As a result, in the present invention, the raw water inflow part includes a first raw water inflow part and a second raw water inflow part, and in the rainy day, the first raw water is collected and purified by the first raw water inflow part, and in the dry water, the second raw water is By selectively collecting and purifying the second raw water inlet, the efficiency of operation as a purifier is not only increased, but since the purifier is continuously operated, there is no fear of bacterial propagation due to the suspension of the purifier.

On the other hand, in the present invention, in addition to purifying through the system as described above in the dry season, it may further include a dry-line circulation line system.

The dry season circulation line system is intended to solve problems such as bacterial propagation due to the stoppage of the purification apparatus in a situation where the second raw water is insufficient, that is, when it is difficult to supply the second raw water.

More specifically, instead of purifying the second raw water and putting it underground, it is a system in which raw water continuously circulates in the purification device in order to prevent bacterial propagation due to the suspension of the purification device.

The dry season circulation line may comprise some or all of the apparatus of the water treatment unit 200 of the present invention, in the present invention, the water collecting tank 40 including the raw water inlet 41 and the level switch 49, automatic It may be configured to include a chlorine injector 50, a disk filtration device 60, activated carbon filtration device 70 and the like. In the dry season, the circulation line is primarily designed to allow chlorine to be introduced from the automatic chlorine injector 50. As the dry season is continued, the water in the sump 40 in which the filtration device is stopped is increased as the pollution concentration increases over time. It may be decayed, in which case chlorine may be introduced from the automatic chlorine input device 50 to prevent decay of water.

On the other hand, the chlorine input according to the automatic chlorine input device may be made in the purification process as described above.

At this time, the level switch 49 set the flow rate in the collection tank 40 during the dry season is automatically sensed, and by supplying chlorine into the collection tank 40 through the automatic chlorine injector 50, the water in the collection tank 40 during dry season In order to adjust the remaining chlorine concentration to 0.2 to 0.4ppm automatically, in the embodiment of the present invention, every 4 days or more every 30 days dry period duration, once every 4 minutes, 30 minutes per dose automatically The circulatory system was designed to suppress bacterial growth in the sump. (See FIG. 4) However, the above-mentioned dry period duration and period are examples, and can be changed as necessary according to the needs of the user.

On the other hand, if the dry season lasts longer than 4 days, the water in the storage tank cannot circulate and the filtration device stops working. Therefore, the pollutant concentration of the collected water increases, which can not be used as water and shorten the life of the filtration devices. There is also.

Therefore, if the dry season lasts longer than 4 days, the circulation line is operated during the dry season so that the preliminary water can be taken into the sump, filtered and purified, thereby operating the filtration device even during the dry season. To ensure the longevity of the device.

To this end, the sump 40 of the present invention may further include a second raw water inlet, that is, a reserve water inlet (41b) in addition to the rainwater inlet (41a) that is the first raw water inlet described above, the reserve water inlet (41b) ) Is connected to the raw water inlet pipe 46 may be introduced into the lower portion of the water collecting tank 40. (See Fig. 2)

The preliminary water may be used by taking the drift water, such as river water or lake water, around the sump into the sump pump 40, and the organic matter or bacteria dissolved in the drift water may be filtered in the sump tank 40 described above. After the same coarse, it can be filtered or purified by circulation line filtration devices during the dry season.

Subsequently, the water filtered in the sump 40 may be filtered through the disk filtration device 60.

Next, the water purified through the disk filtration device 60 may be purified through the activated carbon filtration device 70.

At this time, the activated carbon filtration device 70 includes a first discharge line (71a) and the second discharge line (71b), the first discharge line (71a) is connected to the above-described ultraviolet flow sterilizer (80) The second discharge line 71b is connected to the water collecting tank 40.

That is, when the raw water passing through the activated carbon filtration device is discharged through the first discharge line, it may be introduced into the groundwater through the following process, and when discharged through the second discharge line, according to the circulation line during the dry season, continuously It can be circulated in the purifier.

That is, according to the dry season circulation line, the raw water is to continuously circulate through the collection tank 40, automatic chlorine injection device 50, disk filtration device 60, activated carbon filtration device 70, to suppress the growth of bacteria in the collection tank. Can be.

4 is a view showing that the purified water by the rainwater and the preliminary water purification device of the present invention to form a pipeline to be injected into the groundwater wells.

Referring to FIG. 4 as an example, a process in which water purified by the rainwater and preliminary water purification apparatus of the present invention is added to the groundwater well is as follows.

Groundwater input wells can use the outlets of existing groundwater wells as they are to input purified water, and excavate deeply from the ground to alluvial or rock layers to collect groundwater through air holes drilled in the lower part of the well pipe, and pump them. New wells can be developed to inject groundwater. In general, new wells can be explored from the point where the excavation depth is more than 20 meters by exploring underground water veins. Can be.

On the other hand, in the excavation step for the development of groundwater wells, the secondary wells 401 having a smaller flow rate may be first explored before the main wells 402 rich in flow rate are explored. In addition, the groundwater forms a vein so that the vein extends from one well to several surrounding areas, and the vein continues to another well (403).

Therefore, in the present invention, as shown in Figure 3, it is preferable to excavate to the ground water well depth (h) of 80 to 120 meters and to install a pipe for ground water input to add a high flow rate of purified water.

For example, when the first well 401, which is the auxiliary well by excavating the point A, is first explored and further excavated to the basement, the second well 402, which is the main well-rich, has been explored. Do not connect the groundwater pipe to the end of the second well 402 to open part of the pipe at the point where the first well 401 is explored so that the treated water can enter and exit the well as well as the first well. do.

Subsequently, the groundwater discharge port at the A point where the plumbing facility is completed can be connected to the rainwater and groundwater purifier according to the present invention to force the purified water to be injected.

At this time, the treated water injected into the groundwater discharge port of the point A may flow into the first well 401, the second well 402 and another well 403 while flowing along the well and the water vein.

On the other hand, if underground water veins are found at point B through the development of groundwater in the surrounding area, the pipes connecting point A and point B are equipped with the water purified by the rainwater and preliminary water purification device of the present invention. You can put in until.

In the above manner, the treated water treated by the rainwater and preliminary water purification device of the present invention can be efficiently introduced into the groundwater well even if the flow rate is large.

According to the rainwater and preliminary water purification device of the present invention as described above, in rainy weather, rainwater is stored, purified and recycled into various waters to cope with water shortage and flood damage, and during the dry season, it is also possible to discharge to rivers, thereby causing damage to floods and droughts. There is an effect to reduce, there is an effect to enable the use of a filtration device by utilizing the spare water even in the dry season when the rain does not come.

In addition, if the filtered and purified rainwater and preliminary water in accordance with the present invention is introduced into the underground well, flows through the underground vein connected to the underground well flows into the aquifer, which serves as the surrounding groundwater and underground reservoirs, By reducing the rainwater purified in the groundwater layer, which is depleted, it is effective to prevent ground sedimentation or soil disintegration.

In addition, the present invention has the effect of assisting the purification of the river or natural water circulation by recycling the water, reducing the groundwater, as well as the effect of the restoration of urban groundwater resources, reduction of urban heat island phenomenon and large rain.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
