According to the present invention, the entire process of treating wastewater is automatically controlled by a controller, and the filter medium is automatically supplied in a quantitative manner according to the wastewater treatment capacity to prevent insufficient or excess filter media, and the wastewater treatment is temporarily suspended in the wastewater treatment step. When the filter is adsorbed and coated on the filter, the water stored in the tank can be circulated and supplied to the filter to keep the coated state without separating from the filter, improving the wastewater treatment efficiency and draining the wastewater filled in the tank when the filter is washed. Automatic wastewater treatment device to clean the sludge and waste filter material adsorbed on the filter surface in a short time by spraying high pressure washing liquid into the filter from the multi-directional nozzle of the manifold mounted radially under the tank The wastewater treatment method.

In general, industrial wastewater, domestic wastewater and wastewater are treated through physical, chemical, and biological treatments. As environmental pollution is gradually intensified, the environmental law is strengthened, and secondary and tertiary treatment facilities (eg, ultrafiltration, membrane method, ion exchange). Resin method, etc.) is being used as a countermeasure, and these newly used treatment facilities are still very expensive to install, and due to the frequent replacement of filters, the overall treatment cost and time are very high. Holding it.

The present inventors have developed and applied a lot of conventional wastewater treatment devices. Among them, the wastewater treatment apparatus of Utility Model Application No. 20-2004-10848 was closed with the cover of the tank so that the wastewater could be treated by continuously supplying the wastewater to the tank with only one pump.

However, the wastewater treatment apparatus solves the conventional problem by simplifying the structure by supplying wastewater to one pump using two pumps for the conventional wastewater treatment, but the valve and other functions are still controlled by the controller. It does not solve the conventional problem of relying on manual labor.

In order to solve this problem, the present inventor has filed and registered Utility Model Registration No. 20-0365423. This wastewater treatment device has a problem that it is not possible to quantitatively supply the filter medium according to the wastewater treatment capacity because the operator manually supplied the filter medium to the filter. Because of this, when insufficient supply of filter medium is provided to the filter, the performance of wastewater treatment is degraded. If the filter is excessively supplied, pores of the filter are easily blocked, and the filter is frequently washed because the wastewater cannot be treated for a long time. There was a problem.

In addition, the conventional method of manually supplying the filter medium in the process of treating the waste water, because the operator must always supply the filter medium while waiting for the wastewater treatment labor is cumbersome, because the waste water treatment state can vary depending on the skill of the skilled worker Workers were required as well as the cause of rising labor costs.

In addition, when the wastewater treatment is suspended during the treatment of the wastewater, the flow of the wastewater pumped to the filter stops, so that the filter medium already adsorbed and coated on the filter does not have an external pressure, so it is easily separated from the filter and mixed with the wastewater. Will sink. Therefore, if the wastewater is treated by driving the pump again, the sludge adheres to the filter surface from which the filter medium has been removed and passes through the micropores of the filter. Because of the frequent washing of the wastewater treatment efficiency was significantly reduced.

In addition, when washing the filter, when the pump is stopped and the waste water supply is stopped and the compressor is driven to supply high pressure air to the lower part of the tank, the inflowed air is mixed with the waste water inside the tank, and the waste water is turbulent or vortex The flexible filter is shaken by this wastewater, and the sludge and waste filter adhering to the surface are washed out.

However, the high pressure air introduced into the tank by the compressor did not vibrate the entire wastewater filled with the tank. Therefore, wastewater located in the lower part of the tank may generate sludge due to vibration, but wastewater located in the upper part of the tank may not clean the sludge because little vibration occurs.

The present invention is to solve all the problems of the conventional wastewater treatment apparatus as described above, the purpose is that the entire process of treating wastewater is automatically controlled by the controller as well as automatically supply the quantitative filter according to the wastewater treatment capacity It is to provide an automatic wastewater treatment apparatus that can solve the problem of supplying the filter medium by hand, that is, a problem caused by insufficient or excessive filter medium.

 The pressure gauge 20 is installed at an appropriate position of the tank 3, that is, the lid 3b so as to measure the pressure of the tank 3, and the pressure gauge 20 communicates with the internal storage space 3a. Is installed.

The pressure measured by the pressure gauge 20 is input to the controller 19 in real time and is designed to adjust the pressure of the tank 3. The pressure gauge 20 is displayed a scale so that the user can visually check the measured pressure. When the scale is displayed on the pressure gauge 20 as described above, even if a failure occurs in the controller 19, when the user sees the scale and the pressure of the tank 3 is higher than the set pressure, the driving of the present invention can be stopped to take safety measures. do.

In addition, the cover 3b of the tank 3 is provided with a pressure control valve 21 for lowering the pressure when the pressure of the tank 3 is higher than the set pressure. The pressure regulating valve 21 is a kind of relief valve and may be installed on the path of the pressure regulating pipe 21a connected to the lid 3b and connected to the water tank 5.

When the pressure control valve 21 is clogged by the sludge during the wastewater treatment and the filter 4 is not smoothly processed, the pressure of the tank 3 is increased. At this time, the pressure is increased by the controller 19 to open the tank ( 3) will lower the pressure. In addition, the pressure of the tank 3 rises due to an external temperature increase during summer in the state in which the driving of the present invention is stopped, so that the water and the filter medium A of the water tank 5 are tanked despite the operation of the supply pump 8 at the initial stage of driving. When not supplied to the storage space (3a) of (3) is opened to lower the pressure of the tank (3).

The pressure regulating valve 21 may be controlled by the controller 19 as a kind of relief valve or manually controlled, and preferably adjusted automatically by the controller 19.

The filter 4 is detachably stored in the storage space 3a of the tank 3 and functions to filter the wastewater supplied to the storage space 3a. These filters 4 are the same as those developed and filed by the present inventors, and are configured in a pipe shape with their ends blocked, and a plurality of them are installed in communication with the head 4a. The head 4a is connected to the discharge pipe 9 to guide the treated water passing through the filter 4 to the discharge pipe 9.

The filter 4 has a flexible synthetic resin material in the shape of a pipe, and a myriad of fine pores are formed on the surface thereof, and coil springs are stored therein to prevent shrinkage or twisting, thereby filtering the wastewater safely. When the filter medium (A) is adsorbed and coated, the diameter of the micropores becomes 0.1 μm or less, thereby effectively treating the wastewater.

The water tank 5 is to mix and store the water supplied to the tank (3) and the filter medium (A), as shown in the upper part is connected to the bypass pipe 10 and the lower part is connected to the input pipe 12 do.

The filter medium feeder 6 is a novel material not developed in the wastewater treatment apparatus developed and filed by the present inventor, and automatically supplies the filter medium A to the water tank 5.

The filter medium feeder 6 is rotatable in the passage of the housing 6a, which has a passage formed in the lower portion so as to store the filter medium A and to be supplied to the water tank 5. And a screw 6b for supplying the filter medium A stored in the housing 6a, and a motor 6c connected to the screw 6b to provide rotational power to the screw 6b.

Since the filter medium feeder 6 can know the amount discharged to the passage of the housing 6a when the motor 6c rotates once, the filter medium A can be easily determined by adjusting the rotation speed of the motor 6c per hour. Can be.

Therefore, when the controller 19 controls the rotation speed of the motor 6c, the supply amount of the filter medium A can be selectively adjusted and automatically adjusted according to the wastewater treatment capacity of the present invention.

The supply pipe 7 is connected to the storage tank 22 for storing the waste water and the storage space 3a of the tank 3 to guide the wastewater into the storage space 3a. The supply pipe 7 is composed of a material that is not corroded well in the wastewater, it can be selectively adjusted according to the type of wastewater.

For reference, the reservoir 22 is mounted to the horizontal sensor 22a to be movable horizontally and vertically. When the horizontal sensor 22a is injured in the waste water and maintains the horizontal state, the waste water is normally supplied to the tank 3, and when the supply of the waste water is completed and converted to the vertical state, the controller 19 detects this and immediately the present invention. Stops driving.

The supply pump 8 is installed on the path of the supply pipe 7 to feed the waste water of the reservoir 22 or the water of the tank 5 and the filter medium A to the tank 3.

In other words, the feed pump 8 is driven when the drive initial filter medium A of the present invention is press-coated to the filter 4. The water and the filter medium (A) stored in the water tank (5) is driven to the tank (3) through the input pipe 12 and the supply pipe (7) in accordance with the driving of the feed pump (8), the filter medium (A) is the filter (4) Press-coated on the surface, and the treated water passing through the filter 4 is circulated back to the water tank 5 via the discharge pipe 9 and the bypass pipe 10, while the filter medium stored in the water tank 5 ( Transfer A) to filter 4 to complete the coating.

In addition, the supply pump 8 continues to operate after the filter medium coating is completed as described above to treat the waste water in earnest.

One end of the discharge pipe 9 is connected to the filter 4 to discharge the treated water purified by the filter 4 to the outside of the tank 3.

The bypass pipe 10 is connected to the discharge pipe (9) and the water tank (5), and supplies the water and the filter medium (A) of the initial drive tank 5 of the present invention to the filter (4) to filter this ( 4) When pressure-coating the filter material (A) on the outside, the water passing through the filter (4) is guided to be collected and circulated through the discharge pipe (9) to the water tank (5).

The discharge pump 11 is installed on the discharge pipe 9 path and pumps the treated water treated by the filter 4 to the outside.

The input pipe 12 is connected to the water tank 5 and the supply pipe 7 so that the filter medium A stored in the water tank 5 together with the initial driving water of the present invention is connected to the tank via the supply pipe 7. The water and the filter medium (A) are introduced into the supply pipe (7) so as to be adsorbed and coated on the filter (4) attached to (3). The inlet 12 is opened and closed by the fourth automatic valve 16, which is opened when the filter medium A is coated on the filter 4.

The first automatic valve 13 is installed on the path of the supply pipe 7 located between the reservoir 22 and the supply pump 8 to filter the water and the filter medium A of the initial tank 5 of the present invention. When supplying the filter medium (A) by adsorption coating on the outside of the filter (4), the supply pipe (7) is closed so that the waste water of the reservoir (22) is not supplied to the storage space (3a) of the tank (3) When the wastewater is treated, the supply pipe 7 is opened so that the wastewater of the reservoir 22 can be supplied to the tank 3.

Therefore, the first automatic valve 13 closes the supply pipe 7 when coating the filter medium A, and opens the supply pipe 7 when treating the wastewater.

The second automatic valve 14 is installed on the path of the discharge pipe 9 located between the filter 4 and the discharge pump 11 to filter the water and the filter medium A of the initial driving tank 5. The discharge pipe (9) is supplied so that the water passing through the filter (4) is not discharged to the discharge pipe (9) but is supplied to the water tank (5) when the filter medium (A) is adsorbed and coated on the outside of the filter (4). When the waste water is treated, the discharge pipe 9 is opened so that the treated water purified by the filter 4 is discharged through the discharge pipe 9.

Therefore, the second automatic valve 14 closes the discharge pipe 9 after the bypass pipe 10 when coating the filter medium A, and opens the discharge pipe 9 when treating the waste water.

The third automatic valve 15 is installed on the bypass pipe 10 path, and supplies the water and the filter medium A of the initial driving tank 5 to the filter 4 to filter the filter material outside the filter 4. The bypass pipe 10 is opened so that the water passing through the filter 4 is circulated to the water tank 5 when adsorption coating of (A) is carried out, and the treatment purified by the filter 4 when the waste water is treated. The bypass pipe 10 is closed so that the water can be discharged to the discharge pipe 9 without being supplied to the water tank 5.

Therefore, the third automatic valve 15 opens the bypass pipe 10 when coating the filter medium A, and closes the bypass pipe 10 when treating the wastewater.

The fourth automatic valve 16 is installed on the input pipe 12 path, and supplies the water and the filter medium A of the initial driving tank 5 to the filter 4 so that the filter medium outside the filter 4 When the A) is adsorbed and coated, the inlet pipe 12 is opened so that the water and the filter medium A can be supplied to the filter 4, and when the waste water is treated, the water and the filter medium A in the tank 5 are treated. The input pipe 12 is closed so that no water is supplied to the tank 3.

Therefore, the fourth automatic valve 16 opens the inlet tube 12 when coating the filter medium A, and closes the inlet tube 12 when treating the wastewater.

The washer 17 is to remove the sludge and the waste filter adsorbed on the surface of the filter 4 by spraying the washing solution at a high pressure on the surface of the filter (4).

This washing machine 17 is remarkably different from that developed by the present inventors, the configuration is a washing pump 17a for pumping the supplied washing liquid to the filter 4 at high pressure, the washing pump 17a and the tank 3 Is connected in communication with the storage space (3a) of the washing liquid supply pipe (17b) for guiding the cleaning liquid pumped by the washing pump (17a) to the storage space (3a), and communicating with the washing liquid supply pipe (17b) In which the nozzle 17c-1 is formed at the end of the tank 3 in the storage space 3a of the tank 3 so as to spray the washing liquid pumped by the washing pump 17a to the filter 4. Fold 17c.

Here, the washing pump 17a and the washing liquid supply pipe 17b use a known one. However, the washing liquid supply pipe 17b penetrates the bottom surface of the tank 3 so that the washing liquid may be supplied into the tank 3.

The washing liquid supply pipe 17b is connected to the plurality of manifolds 17c to be described later one-to-one and connected to the washing pump 17a so that a plurality of pipes are provided. The reason why the washing liquid supply pipe 17b is independently connected to each manifold 17c is that when the filter 4 is washed, all of the washing liquid pumped by the washing pump 17a is transferred to any one washing liquid supply pipe 17b. This is to allow only the passage of the washing liquid to be injected into the filter 4 at a high pressure.

That is, the washing liquid pumped by the washing pump 17a sequentially passes through the independent washing liquid supply pipes 17b so as to be sprayed at high pressure on the filter 4 so that the sludge adsorbed on the filter 4 and the waste filter material can be washed. It is.

Each of the washing liquid supply pipes 17b is equipped with a valve (not shown) for controlling the flow of the washing liquid, and the valves are opened and closed sequentially by the control of the controller 19.

As shown in FIG. 8, a plurality of the manifolds 17c are disposed radially under the tank 3, and each manifold 17c is connected to the washing pump 17a by an independent washing liquid supply pipe 17b.

A plurality of nozzles 17c-1 of the manifold 17c are arranged in multiple directions in a regular or irregular manner so that the washing liquid can be sprayed in multiple directions and supplied to the filter 4.

The drain pipe 18 is connected to the drain port 3c of the tank 3 so as to guide discharge of the sludge and the waste filter material washed by the washer 17, and the drain valve 18a is mounted on the path. .

Wastewater is discharged by opening the drain pipe 18 and the washing machine 17 is driven to spray the washing liquid at a high pressure to the filter 4 to automatically clean the sludge and the waste filter.

The controller 19 sets the driving order and time of the components in advance for wastewater treatment and automatically controls them in the wastewater treatment process.

The following describes an automatic wastewater treatment method according to the present invention.

According to the present invention, the wastewater treatment is performed by the control of the controller 19.

Supplying the filter medium (A) to the water tank (5) in which water is stored using the filter medium feeder (S1);

Close the first and second automatic valves (13) and (14), open the third and fourth automatic valves (15) and (16), drive the supply pump (8), and stop the discharge pump (11). Water and filter medium (A) stored in 5) is supplied to the storage space (3a) of the tank (3) via the input pipe 12 and the supply pipe (7) so that the filter medium (A) is adsorbed outside the filter (4) The water passing through the filter 4 is repeatedly circulated for a predetermined time to be circulated to the water tank 5 via the discharge pipe 9 and the bypass pipe 10 to coat the filter material A with the adsorption coating. Making step (S2);

The first and second automatic valves 13 and 14 are opened, and the third and fourth automatic valves 15 and 16 are closed, and the supply pump 8 and the discharge pump 11 are driven to Waste water is supplied to the tank 3 and filtered by the filter 4 coated with the filter medium A, and the treated water purified through the filter 4 is discharged to the outside through the discharge pipe 9 to discharge the waste water. Processing step S3;

In the step of treating the waste water, the controller 19 measures whether the sludge is adsorbed to the filter 4 so that the pressure of the tank 3 rises above the set pressure (S4);

In the step of treating the waste water, when the sludge is adsorbed to the filter 4 and the pressure in the tank 3 rises above the set pressure, the controller 19 stops the operation of the supply pump 8 and the discharge pump 11. The first and second automatic valves 13 and 14 are closed to block the inflow of wastewater into the tank 3, and then the drain valve 18a is opened to drain the wastewater stored in the tank 3 into the drain pipe 18. Discharging to the outside through the (S5); And

When the waste water is discharged from the tank 3, the automatic washing machine 17 is driven to sequentially supply the cleaning liquid to each manifold 17c mounted in the tank 3, thereby providing a plurality of nozzles formed in each manifold 17c. And a washing solution sprayed at high pressure at 17c-1 to the filter 4 to wash the sludge adsorbed outside the filter 4 and the waste filter material (S6).

Here, when the filter washing step (S6) is completed, it is repeatedly carried out from the filter medium supply step (S1) of the first step to the filter washing step (S6) of the finishing step again to automatically treat the waste water.

When the wastewater treatment is suspended or stopped in the step of treating the wastewater (S3), it is detected (S7), and when the driving of the device is stopped, the filter medium (A) already adsorbed and coated on the filter (4) is filtered (4). To close the first and second automatic valves (13) and (14), to open the third and fourth automatic valves (15) and (16), to drive the feed pump (8) so that the coating state can be maintained without being separated. The discharge pump 11 is stopped, and the water stored in the water tank 5 is supplied to the filter 4 via the input pipe 12 and the supply pipe 7 and the discharge pipe 9, the bypass pipe 10, and the water tank. The method further includes a step S8 of circulating and supplying the filter 4 again via (5).

In the step (S1) of supplying the filter medium (A) to the water tank (5), since the driving time, driving time, and filter medium supply amount of the filter medium feeder (6) are input in advance to the controller (19), the filter medium feeder (6) Driven only when coating the filter 4.

Adsorption coating of the filter medium (A) to the filter (4) (S2) is because the feed pump (8) pumps the filter medium (A) and water stored in the water tank (5), the controller 19 is input in advance The filter medium A is coated on the filter 4 by controlling the driving time and timing of the supply pump 8 according to the information.

The step S3 of treating the wastewater proceeds within a range in which the pressure of the tank 3 does not exceed the set pressure, and when the pressure of the tank 3 exceeds the set pressure, the controller 19 determines the driving of the present invention. After the washing step (S6) to proceed.

Step (S4) of measuring the pressure of the tank (3) is the reservoir 22 by the supply pump (8) in the state that the fine pores of the filter (4) is blocked by the sludge and the filter (4) did not process the waste water smoothly Since the waste water is continuously pumped into the tank 3, it is determined at this time whether the pressure inside the tank 3 rises.

When the pressure of the tank 3 is increased by the continuous wastewater treatment, a step S5 of discharging the wastewater stored in the tank 3 is performed as a preparation step for washing the filter 4. This step is to stop all functions of the present invention and open the pressure regulating valve 21 and the drain valve 18a so that the waste water stored in the tank 3 is discharged through the drain pipe 18.

When the waste water is completely drained from the tank 3, the filter washing step (S6) is carried out. In the filter washing step (S6), the controller 19 drives the washing machine 17 to sequentially supply the washing liquid to each washing liquid supply pipe 17b so that the multidirectional nozzle 17c-1 mounted to each manifold 17c. By spraying the filter 4 at a high pressure through it to wash the filter (4). The running time of the washer 17 can be obtained by the repetitive test to remove the sludge and waste filter material from the filter 4 cleanly and input the time to the controller 19 to control the running time of the washer 17. Done.

Next will be described in detail the process of treating wastewater using the wastewater treatment apparatus according to the present invention configured as described above.

First, a suitable amount of water is filled in the water tank 5, and the filter medium A is quantitatively injected into the water tank 5 according to the previously inputted information using the filter medium feeder 6. The filter medium (A) may be variously determined according to the type of wastewater, and activated carbon widely used in the present invention is used.

When the filter medium is introduced into the water tank 5, the feed pump 8 is driven to pressurize the water and the filter medium A stored in the water tank 5 to the tank 3 so that the filter material A is coated on the filter 4 by adsorption. And the water passing through the filter 4 is circulated back to the water tank 5 to coat the filter medium A on the filter 4. In this process, the controller 19 closes the first and second automatic valves 13 and 14, opens the third and fourth automatic valves 15 and 16, and stops the discharge pump 11.

When the coating of the filter 4 is completed, the feed pump 8 and the discharge pump 11 are operated simultaneously to pump the wastewater filled in the reservoir 22 to the filter 4 so that the sludge contained in the wastewater is filtered (4). The filtered water is passed through the filter (4) is discharged to the outside through the discharge pipe (9) to proceed with the wastewater treatment.

When the wastewater is treated for a long time and the micropores of the filter 4 are blocked and the pressure of the tank 3 rises above the set pressure, all functions are stopped by the controller 19 and the wastewater stored in the tank 3 is drained. And then the washing machine 17 sequentially supplies the washing liquid to each manifold 17c so that the washing liquid sprayed from the nozzle 17c-1 is washed with the sludge and the waste filter material adsorbed to the filter 4. Done. At this time, the valves of the washing liquid supply pipe 17b through which the washing liquid is pumped are sequentially opened and closed by the controller 19 so that the pressurized washing liquid passes sequentially through each washing liquid supply pipe 17b.

In this series of wastewater treatment processes, if the driving stops for any reason and the wastewater treatment is suspended, the feed pump 8 is immediately driven to circulate the water stored in the water tank 5 to pass through the filter 4 so as to filter (4). Do not separate the filter media (A) coated on the).

As described above, the present invention for treating wastewater can automatically treat wastewater under the control of the controller 19. When the filter 4 is not separated, the waste water is discharged from the tank 3 when the filter 4 is washed, and then the filter 4 can be cleaned in a short time by spraying the washing liquid at a high pressure on the filter 4, and thus, the conventional wastewater treatment apparatus. In contrast to this is an advantageous invention.
