The present invention relates to a technology for efficiently removing contaminants contained in river water while passing through a pore-controlled dual filtration device, and subsequently reacting with a water purification agent to remove contaminants and other contaminants such as algae to supply cleaner water to the river maintenance water. .

In general, the flow rate of the stream consists of the flow from the upstream and the groundwater seeping out from the bottom of the river, etc.As a result of urban development, the stream is dried up and the basic flow of the river is reduced. There is a very lack of water for maintenance, that is, river maintenance water.

The filtration device and purification method for the purification of river maintenance water is not particularly provided, but only the facilities for supplying river maintenance water are operated.

There is a lot of existing uses for other filtration devices and flocculants other than the related technology for the purification of river maintenance water. For example, the filtration apparatus includes a sand filter, activated carbon filter, fibrous filter, membrane filter, etc., and the flocculant includes various chemicals used in flocculation sedimentation such as aluminum sulfate, ferric sulfate, and ferric iron.

However, in order to purify the huge amount of river maintenance water using the existing filtration device, the initial investment cost is very high, the floating material removal efficiency is high, the maintenance cost is very high, and the coagulant used is very If it is harmful and is not treated precisely, it may adversely affect the river.

In addition, there are many problems in the treatment of sediment sludge.

The present invention is to provide a water purification device and a method for purifying river maintenance water by using a pore-controlled dual filtration device and a water purification agent, the river water is switched to the upstream when the river water supply, the air gap is automatically Allow the suspended solids to be primarily filtered while passing through the flotation media, which are reduced in size, and the primary filtered stream water passes through the smaller pores of the stretchable media that automatically vary the gap using buoyancy. Even the contaminants of the fine particles can be filtered secondarily, and the secondary filtered river water undergoes a chemical reaction with the water purifier while passing through the mixing tank into which the water purifier is introduced, causing various contaminants such as algae to flocculate and then flocculate. The problem to be solved is that the injured sludge can be stored in the total sludge storage tank.

In addition, the present invention is that when the supply of river water is stopped and the filtration operation is in a lull state, the contaminant particles attached to the stretchable media together with the remaining water in a natural drainage method through the enlarged pores as the elastic median relaxes so that they can detach themselves. To be a problem of the invention.

In addition, the present invention is to solve the problem that the sludge stored in the sludge storage tank to be automatically discharged to remove the sludge removal device to the outside while reciprocating.

The present invention is a means for solving the above problems by installing a primary flotation tank filled with a buoyancy filter in the lower side of the river water treatment tank, starting from the fixed perforated plate fixed horizontally installed on the upper portion of the primary flotation tank Separately install the filtrate chamber and the secondary compression filtration tank in the upper and lower sides, respectively, and install the buckle and the stretchable filter in the filtrate chamber and the secondary compression filter, respectively, but the traction rod connected to the lower end of the mouth passes through the fixed perforated plate and the stretchable media The present invention provides a technique for providing a pore-controlled dual filtration device integrally connected with a porous crimp plate.

In addition, the present invention is continuously installed in the inside of the rectangular water filtration tank of the pore-controlled dual filtration device, the upper portion of the pore-controlled dual filtration device to collect all the filtered water while passing through the filtration device to guide the front A water collecting duct is installed, and a water purification agent is introduced into the mixing tank formed at the front upper portion of the water collecting duct to inject and supply the water purification agent into the river water supplied through the water collecting duct to flocculate and float residual contaminants.

In addition, the present invention performs a primary flotation process for supplying the river water to the primary flotation tank to remove the suspended matter primarily, and interlocked with the buoys rising as the water level of the primary filtered stream water increases. Secondary compression is performed by compressing the stretchable media using a porous crimp plate, and removing the contaminants of the fine particles secondarily while passing through the small pores of the compressed stretchable media through the primary filtered stream water. While performing the filtration process, the secondary filtered river water is passed through the inside of the mixing tank into which the water purification agent is introduced, and various contaminants such as algae are flocculated to the water through chemical reaction with the water purification agent, and then the aggregation is performed in the sludge storage tank. Perform the flocculation flotation removal process for storing the floated sludge, and complete the flocculation flotation removal process. We will devise a new concept of river maintenance water purification technology that sequentially performs the purification water supply process of pumping clean purified water and supplying it to river maintenance water upstream.

According to the present invention, a large amount of river water is passed through a pore-controlled dual filtration device to remove contaminants, and then the pollutants such as algae are repeatedly removed by flocculation flotation through chemical reaction with a water purifier to maintain the stream more cleanly. By supplying with water, it secures stability according to the maintenance of river maintenance water, and in particular, it provides the effect of restoring eco-friendly ecological rivers where clean water always flows.

In addition, the present invention is excellent in filtration performance by repeatedly filtering the contaminants of the fine particles that are not removed by the river water passes through the small pores of the stretchable media that can automatically control the pores without using a separate power, The stretchable media filters the filter media without any filtering while filtering and removing the contaminant particles attached to the stretch media by the remaining water drained by the natural drainage method as the air gap increases automatically when the filtration operation is performed. Provides the effect that can be easily implemented by the self-cleaning method.

The water purification tank 100, which is one component of the river maintenance water purification device (F), consists of a rectangular box, but has an inflow passage 101 for supplying the river water therein under the front wall 102. It is formed to communicate with, the lower side of the rear wall 103, the pumping pump 104 for pumping the purified water completely purified and pumped upstream of the stream (1) is connected to the water supply.

A central wall 106 is installed upright on the inner bottom surface 105 of the water purification tank 100, and a plurality of air gap controlled dual filtration, which is a core technology of the present invention, is provided between the central wall 106 and the front wall 102. Since the device 200 is continuously installed to be able to filter a large amount of river water smoothly and complex at a time, it is installed in multiple stages by switching the direction of the river water flowed through the inflow passage 101 to the upward flow. The secondary flotation filtration tank 220 and the stretchable filter medium 250 are sequentially filtered while being passed through.

The technical configuration of the air gap controlled dual filtration device 200, which is the core technology of the present invention, is mounted on the upper portion of the support 211 installed on the bottom surface 105 as shown in Figs. A stream water treatment tank 210 having a filtered water outlet pipe 212 connected to the inside thereof, the lower portion of which is opened so that the river water introduced through the inflow passage 101 is introduced into the inside; A pair of porous plates 221 are spaced up and down at a lower side of the river water treatment tank 210, and the buoyancy filter 222 is filled between the porous plates 221 and the primary flotation tank 220. ; A filtrate chamber 231 communicating with the filtrate outlet pipe 212 is installed on an upper side of the fixed porous plate 230 fixed to the upper portion of the primary flotation tank 220, and moves up and down in the filtrate chamber 231. A buoy 240 capable of being installed; A stretchable filter medium (250) disposed in the second compression filtration tank (232) formed under the fixed porous plate (230); It is disposed on the lower side of the stretchable media 250, integrally connected to the lower end of the pull rod 241 through the fixed perforated plate 230 and the stretchable media 250 in a state connected integrally to the buckle 240 is the buckle It is configured to include a porous pressing plate 260 interlocking with the 240 up and down.

Here, the river water treatment tank 210 is seated on the upper portion of the support 211 installed on the inner bottom surface 105 of the water purification tank 100, but the upper portion to allow the filtered water to flow into the inside of the water collecting duct 300.

The buoyant filter medium 222 is made of a material having a specific gravity smaller than that of water, so that when the river water is supplied, it floats upward as shown in FIG. If the filtration operation is stopped and the filtration work is in a lull state, it naturally sinks to the lower part, and as the pore grows to its original state, the pollutants accumulated in the pore can be smoothly discharged to solve the clogging phenomenon of the pores. It becomes possible.

At this time, the present invention is further grafted with a technology corresponding to a pretreatment process for sedimentation and removal of coarse particles having a relatively large particle size before performing a full-scale filtration operation by the primary flotation tank 220. As shown in FIG. 1, the sedimentation tank 108 for additionally removing and removing coarse material of 1 mm or more included in the river water flowing through the river water inflow pipe 107 is installed and connected to the outside of the front wall 102. ) Inside the partition wall 110 is formed with a floating screen 109 is installed, between the partition wall 110 and the front wall 102 guides the stream water from which the coarse material precipitated to the inlet flow path 101. A river water induction furnace 111 that performs a role is further formed.

It is finally supplied to the primary flotation tank 220 to provide an effect of further improving the filtration performance.

The fixed perforated plate 230 is horizontally installed on the upper portion of the primary flotation tank 220, and the filtered water chamber 231 is a space in which the filtered water which temporarily completed the filtration process stays on the upper side of the fixed porous plate 230. ) Is formed to communicate with the filtered water outlet pipe 212, by selectively moving up and down by the buoyancy buoyancy buoyancy to compress or relax the stretchable media 250 without a separate power source without using a separate power source Floating ball 240 to serve to make is installed.

A secondary compression filtration tank 232 is formed on the lower side of the fixed porous plate 230 to filter the first filtered river water secondaryly, and a stretchable filter 250 is installed in the secondary compression filtration tank 232. do.

The stretchable filter 250 is made of a material having elasticity that the pores are reduced or relaxed as the pores are selectively compressed, and when the pores are made smaller, the pores become larger while the pores are made larger.

While interlocking together, it selectively serves to compress or relax the stretchable mediator 250, and the primary filtered water passing through the porous crimp plate 260 is supplied to the stretchable mediator 250.

That is, the porous crimping plate 260 is integrally connected to the buoy 240 through the traction rod 241, and thus stretches the elastic media 250 while interlockingly moving with the buoy 240 moving upward when supplying the river water as shown in FIG. ) Compresses even the finer contaminants as the pores of the stretchable filter medium (250) becomes smaller, significantly improving the filtration performance, and when the filtration treatment operation is suspended because the supply of river water is stopped, the stretchable filter (250) ) Relaxes to its original state and as the voids become larger, it is possible to smoothly remove the contaminant particles stuck to the stretchable filter medium 250.

In addition, the stretchable media 250 is contaminant particles stuck to the stretchable media 250 in a natural drainage method as the natural water is drained down through the voids in which the residual water functioning in the process of relaxing to the original state as the river water supply is stopped. Detach more smoothly and clean the pores by itself to eliminate the clogging of the pores, and provides the effect of such self-cleaning is automatically performed without a separate power supply without using a separate power supply.

In addition, the contaminant particles discharged to the lower side by the self-cleaning as well as the flocculated foreign matter agglomerated on the porous pressing plate 260 is automatically discharged to the lower side of the primary flotation tank 220 so that the worker can collect them.

In addition, when the supply of the river water is stopped, the flow path of the check valve 271 is opened by the water pressure due to the remaining water naturally discharged from the stretchable filter 250, so that the pollutant particles and the foreign matter are firstly filtered through the foreign substance discharge pipe 270. As it smoothly discharges to the lower side of the 220, the first buoyant filtration tank 220, as well as the secondary compression filtration tank 232 and stretchable filter 250 neatly filtered during the lull state of the filtration operation to further filter performance. While improving, it is possible to provide convenience according to the maintenance of the filtration device by omitting the filtering work performed by putting a separate manpower.

The water passage 303 is formed.

Accordingly, all the filtered water flowing out of each filtered water outlet pipe 212 is guided to the front (front wall direction) along the water collecting passage 303 while being collected in the water collecting duct 300, and the water passage 301. After passing through the rear direction is changed to flow the upper portion of the collecting duct (300).

In addition, the water purification agent injector to the front upper portion of the water collecting duct 300 by injecting a water purification agent into the filtered water flowing backward through the water passage 301 to remove even the remaining contaminants remaining in the filtered water by flocculation ( 400) is installed.

At this time, the upper part of the water collecting duct 300 is a water mixing agent 500 to provide a sufficient chemical reaction time by reducing the flow rate of the filtered water so as to further promote the flocculation flotation of the residual contaminant while the water purification agent and the filtered water cause a long-term chemical reaction Is prepared.

The mixing tank 500 is a plurality of flow rate lower plate 511 is installed on the inner surface of both side walls 113, as shown in Figure 5 are spaced at equal intervals, respectively, the flow rate lower plate 511 is a flow path through which the filtered water ( 512 is repeatedly formed in a zigzag form alternately from left to right, and the filtered water flows inside the mixing tank 500 for a long time along the curved flow path 512 to remove contaminants such as algae through sufficient chemical reaction with the water purification agent. Flocculate flotation to the water surface, the flocculated contaminants are converted to sludge and moved backwards.

In addition, the water purification tank 100 is a sludge storage tank 601, the front of which is opened on the inner upper portion of the rear wall 103 is installed to collect and store the total amount of sludge that is flocculated and moved to the rear, the sludge storage tank 601 The sludge stored in the sludge removal apparatus 600 as shown in FIGS. 6 and 7 can be discharged and removed to the outside.

A screen filter 606 is coupled to the outside of the moving shaft 604 so as to be pivotable up and down, but a weight 607 is installed below the screen filter 606 to move the inside of the sludge storage tank 601. In the process, the sludge can be smoothly filtered while maintaining the vertical position without turning.

Accordingly, the screen filter 606 moves in a vertical state together with the moving shaft 604 as shown in FIG. 7 to filter the sludge injured on the surface and reach the side wall 113 in the moving shaft 604. The screen filter 606 may move upward beyond the side wall 113 by being pivoted upward while being caught to the outside of the sludge storage tank 601 to discharge and remove the sludge to the outside. Will be.

Next, a stream maintenance water purification method using the air gap control type dual filtration device 200 and the water purification agent of the present invention having the above configuration will be described.

1) First flotation filtration process (S10)

In this process, the river water is supplied to the primary flotation tank 220 by supplying the river water that is turned upward while passing through the inflow passage 101 formed in the water purification tank 100 into the primary flotation tank 220. Various suspended solids can be primarily removed while passing through the small gap of the buoyant filter medium 222.

2) Elastic media crimping process (S20)

As the water level of the primary filtered river water increases, the buoy 240 automatically rises, and the buoy 240 and the porous pressing plate 260 are integrally connected to each other so that the porous ball interlocks with the buoy 240. The stretchable filter medium 250 is compressed by using the pressing force of the pressing plate 260.

That is, the porous pressing plate 260 rising together with the buoy 240 may compress the stretchable filter medium 250 to form a condition in which the pores of the stretchable filter medium 250 may be reduced while filtering contaminants of even finer particles. Will be.

3) Second compression filtration process (S30)

When the elastic medium 250 is compressed and the pores become smaller, the small pores are passed through the first filtered river water, thereby filtering the contaminants of the fine particles that have not been removed through the first flotation process. It provides the effect of dramatically improving the filtration performance.

4) Admixture Treatment Induction Process (S40)

The secondary filtered filtrate is separated and discharged from each of the plurality of pore-controlled dual filtration device 200 to collect them all at once to guide the total amount to the mixing tank 500 for additional water purification according to the flotation flotation method using the water purification agent. Process is needed.

To this end, the secondary filtered filtrate is collected by a collecting duct 300 to guide the flow forward along the collecting passage 303 and then mixed with the water passage 301 to be mixed. Induction supply to

5) Cohesion Flotation Removal Process (S50)

Most of the contaminants have been removed from the filtered water supplied to the mixing tank 500, but the water purification agent injector 400 installed in the mixing tank 500 is operated to completely remove even the remaining contaminants that have not been removed. Into the inside of water), add a water purifier.

At this time, the filtered water flows inside the mixing tank 500 in the form of a zigzag and stays for a long time, causing a long-term chemical reaction with the water purification agent to more flocculate and float the remaining contaminants to the water surface, such contaminants of the sludge Is converted to a form.

6) Purified water supply process (S60)

The purified water purified through the flocculation flotation process is pumped by operating the pressure pump 104 and then supplied to the stream holding water upstream of the stream (1) through the water supply pipe (3) to replenish the insufficient river maintenance water. While playing a role, it is possible to create eco-friendly ecological rivers with clean water flowing at all times.

7) Sludge Removal Process (S70)

This process is a process for automatically discharging and removing the sludge that is stored in the sludge storage tank 601 as a sludge storage tank 601 while the flotation flocculates to the water surface to the outside automatically.

To this end, the sludge stored in the sludge storage tank 601 is filtered through a screen filter 606 periodically reciprocating along the guide rail 603, and the sludge storage tank 601 is continuously moved while the screen filter 606 is continuously moved. By pulling out the outside of the screen filter 606, the sludge filtered out can be discharged to the outside and removed.

8) Filtering Self Cleaning Process (S80)

When the filtration operation is stopped by stopping the river water supplied to the primary flotation tank 220 through the inflow passage 101, the contaminant particles attached to the stretchable filter 250 are not used without using a separate power source. In addition, a process of detaching the power supply from the power source and cleaning the voids by itself is added.

That is, when the supply of the river water is stopped, the compressive force of the porous pressing plate 260 interlocked with the buoy 240 which automatically descends according to the water level is released, and at the same time, the stretchable media 250 in the compressed state is automatically relaxed. Contaminant particles can self-desorb together with the residual water through the pores, and this self-cleaning process such as this can only be performed for a limited time only when the filtration operation is performed by stopping the supply of river water.
