The present invention relates to an operation control method of a water treatment facility through three-point pressure measurement and an operation control device using the same.

In recent years, in terms of protection of water resources, effluent quality standards in sewage treatment plants have been continuously strengthened.

Various water treatment processes have been developed and applied in order to comply with such enhanced water quality standards, and a representative one of such water treatment processes is a biofiltration process.

1 is a cross-sectional view schematically showing a terrestrial biofilter according to the prior art, Figures 2 and 3 is a view showing the operation of the terrestrial biofilter according to the prior art, Figure 4 is a terrestrial biological according to the prior art It is a figure which shows the head loss of a filter paper.

As shown in the figure, the terrestrial biofilter 100 according to the prior art is composed of a configuration including an inflow channel 101 and the outflow channel 106.

The inflow channel 101 is an inlet pipe 102 for introducing sewage and both sides of the inlet weir 103 and the inlet weir 103 for inducing the flow of sewage introduced through the inlet pipe 102. Is provided in each is provided with an inlet sluice 104 for preventing the outflow of sewage.

In addition, the inlet pipe 102 is provided with an inlet valve 105 for controlling the flow and flow rate of the sewage flowing in.

The outflow channel 106 is for flowing out purified water after flowing through the inflow channel 101 and is located below the inflow channel 101.

Here, the filter paper 107 is provided on one side of the inlet pipe 102, and the filter medium 108 for filtering contaminants such as solids contained in the sewage is provided on the filter paper 107.

The biological filtration process of the biological filter paper having the structure as described above, because the biological treatment and the physical filtration is performed at the same time, it is possible to secure excellent treated water quality, and in particular, it is possible to achieve stable nitrification at low water temperature in winter. Have

On the other hand, in the case of the biofiltration process, as the amount of solids detained in the filter medium increases as the filtration continues, the loss of the filtration is finally increased and the inflow water level is increased.

That is, as shown in Figures 2 to 3, if the filtration is continued, the amount of contaminants such as solids held in the filter media increases, thereby increasing the filtration loss and the inflow water level by reducing the voids There was this.

In order to solve the problem as described above, if a constant filtration loss occurs, the filtration can not be continued, it is necessary to recover the head loss by removing the detained solids through backwash.

For this purpose, the backwashing time of the biofiltration is determined, and the backwashing time of the biofiltration is determined by the head loss of the filter medium.

Thus, the head loss of the media is measured by installing a water gauge on the upper part of the inlet pipe, as shown in FIG. That is, the backwashing time of the biological filter is determined by measuring the head loss of the filter medium by installing a water gauge at a position close to the inflow channel located at the top of the inlet pipe.

Here, mechanical, electrical, ultrasonic water level gauges, etc. can be applied as a water level meter, but there was a disadvantage in that an error such as noise is frequently generated in the measured value according to a level change caused by a drop in the inflow channel during the level measurement.

In addition, there was an operational problem such that the water level of the filter paper undergoing filtration decreases with the discharge of backwash water during backwashing, and the measured value of the inflow water level decreases, causing errors such as head head loss.

On the other hand, in recent years, underground sewage treatment plants have been increasing, which means that when the sewage treatment plant is constructed underground, construction and construction costs are reduced, so the application of underground biofilters where the inflow channel is located below the outflow channel is increasing. to be.

These underground biofilters consist of a structure in which sewage is introduced by connecting an inlet pipe to an inflow channel maintained at a constant pressure, but there is a problem that the head loss of each biofilter cannot be measured through a water gauge.

On the other hand, in the case of small sewage treatment plants, most of them are built underground, but the batch reactor suitable for the small sewage treatment plant is operated by measuring the inflow water level. .

The present invention has been made in order to solve the problems as described above, by measuring the pressure value in the biological reactor and converting and calculating the measured pressure value to the water level value backwashing time by determining the optimum backwashing time and discharge point And control method of water treatment facilities through three-point pressure measurement that can be applied to underground bioreactors, where it is difficult to determine the backwashing point because it is impossible to install water gauge to determine the discharge point It is an object to provide a control device.

In order to achieve the object as described above, the present invention is characterized by determining the backwashing time of the biofilter by converting and calculating the pressure value measured in the pressure gauge installed at the three points of the biofilter as a level value.

In addition, the discharge value of the batch bioreactor may be determined by converting and calculating the pressure value measured by the pressure gauge installed at three points in the batch bioreactor.

Here, the pressure gauge is located at the lower part of the filter paper, the lower part of the filter medium located above the filter paper, and the upper part of the filter medium to measure the pressure.

At this time, the head loss and the slope calculated by the pressure are used simultaneously when determining the backwashing point.

On the other hand, the backwash time operation control device for determining the backwash time point, the pressure gauge for measuring the pressure in the filter paper; A first automatic control unit provided with a measured value measured by the pressure gauge; A second automatic controller connected to the first automatic controller via a network; And a pump / valve connected to the first automatic control unit for facility control. Characterized in that consisting of a configuration including a.

Here, the pressure gauge is provided at the lower part of the filter paper, the lower part of the filter medium located above the filter paper, and the upper part of the filter medium, respectively.

In this case, the first automatic control unit includes an automatic control device that receives the measured value of the pressure gauge, and a control device that transmits / receives an analysis result and a control result of the automatic control device.

The control device includes an operation module for recording the backwash cycle, a storage module for storing the backwash cycle recorded in the operation module, an input / output device for displaying the backwash cycle stored in the storage module in graphic and text, and input / output. The device is configured to include a communication module that transmits the analysis and control results according to the input loss head value and transmits a new setting value.

On the other hand, the control device determines whether the first or second automatic control panel is in the backwash state when performing the backwash, and if the first or the second automatic control panel is not in the backwash state, the control unit reverses the second or the first automatic control panel. When performing the cleaning or when the first or second automatic control panel is in the backwash state, the process is performed to switch to the standby state, wait until the backwash is completed, and then perform the backwash of the control panel.

It is a figure which shows schematically.

As shown in the figure, the operation control method of the water treatment facility through the three-point pressure measurement according to the present invention, the installation of the water gauge and the filter paper 27 of the underground biofilter 20 that can not measure the water level through it After installing pressure gauges (10a, 10b, 10c) in the lower portion and the upper portion of the filter medium 27 installed above the filter paper 27 and the upper portion of the filter medium 28 to measure the pressure at each point of the biological filter paper (20) Determine the backwash time

That is, the sewage is introduced through the inlet pipe 22, and the filter paper 27 is introduced through the inlet passage 21 and the inlet passage 21 for flowing the sewage flowing through the inlet tube 22. The filter paper 27 is provided on one side of the inflow passage 21 in the underground biofilter 20 having a constitution including an outflow passage 26 for outflowing purified water through the filter media 28 of the filter media 27. The pressure gauge 10a is installed at the lower part of the head), the pressure gauge 10b is installed at the lower part of the filter medium 28 located above the filter paper 27, and the pressure gauge 10c is mounted at the upper part of the filter medium 28. After the installation of each of the three pressure gauges 10, such as installed by measuring the pressure of the pressure gauges 10a, 10b, 10c installed at each point to determine the backwash time of the biological filter paper 20.

As described above, after installing the pressure gauge (10a, 10b, 10c) on the upper and lower portions of the filter paper 27 and the filter medium 28 of the underground biofilter 20, respectively, in the lower portion of the filter paper 27 The height up to the bottom of the media 28 is represented by H _b , the height from the bottom of the media 28 to the top of the media 28 is represented by H _m , and the height from the top of the media 28 to the outflow water level is H. _It is represented by _w and the height from the outflow water level to the inflow water level is represented by ΔH.

Here, the distribution of the position head and the pressure head when the head loss does not occur in the position head according to the position of the underground biofilter 20 is shown in FIGS. 8 and 9. .

At this time, when the position head is represented by H _T and the pressure head is represented by P _T , the following relationship is established between the position head and the pressure head (where the water level 1m = pressure 0.1kgf / cm ² ).

H _T = H _W + H _m + H _b

P _T = P _W + P _m + P _b

H _T = P _T

)는 위치수두와 압력수두의 변화가 같기 때문에 1을 나타낸다.At this time, as shown in Figure 8, the slope of the straight line (

Denotes 1 because the change in position head and pressure head is the same.

And, the height value H _m from the bottom of the filter medium 28 to the top of the filter medium 28 can be easily obtained in consideration of the input amount of the filter medium 28 and the area of the filter paper determined in the design, the filter medium 28 P _m , the pressure value from the lower part of the upper part to the upper part of the filter medium 28, may be obtained as a difference between the pressure value P ₃ of the upper part of the filter medium 28 and the pressure value P ₂ of the lower part of the filter medium 28.

Here, when there is no head loss (ΔH = 0), since the value of the pressure gauge 10 remains in the same state as the water pressure, H _m = P _m is established and the slope becomes 1.

At this time, the correlation between the position head H _T and the pressure head P _{T of the} pressure gauge 10 is as follows.

H _W + H _m + H _b = P ₁ = P _T

H _W + H _m = P ₂

H _W = P ₃

로 변화하게 된다.On the other hand, if the filtration is continued, the head loss occurs in the filter media 28 due to the increase of the solids in the influent and the microorganisms grown on the surface of the filter media, and the inflow head is increased, and the pressure distribution at this time is shown in FIG. , The head loss in the media 28 increases and the slope of the straight line (

)end

To change.

At this time, the correlation between the position head H _T and the pressure head P _T is as follows.

△ H + H _W + H _m + H _b = P ₁

ΔH + H _W + H _{m =} P ₂

H _W = P ₃

Here, it is possible to verify whether the measured value of the pressure gauge 10 is correct. As shown in the following equation, the difference between the pressure value P _{1 at the} bottom of the filter paper 27 and the pressure value P _{2 at the} bottom of the filter medium 28 is designed. It should be equal to the difference between the position heads H _T of the two pressure gauges 10b and 10c.

P ₁ -P ₂ = P _b = H _b

If a difference in value occurs, it is necessary to check that the pressure gauge 10 is abnormal.

At this time, the pressure according to head loss can be calculated using the following equation.

P ₂ -P ₃ = P _m + ΔP = H _m + ΔH

H _{m, which} is the height from the bottom of the filter media 28 to the top of the filter media 28, is a value determined at design time, so that the head loss value ΔH generated at the filter media 28 of the underground biofilter 20 is present. Accurate calculation is possible because it is possible to accurately know the head loss of the underground biofilter 20 that can not install the water gauge is possible precise operation. The backwash point is determined according to the design conditions at the time of design, and backwashing is performed when the head loss value is equal to the determined value during operation.

In addition, it is possible to control through the head value and the slope value according to the head loss that is utilized as the water level value in the media 28 together with the control through the simple water level prediction. That is, if the head loss of the filter medium 28 does not occur, the slope of the straight line is represented by 1. When the head loss occurs, the slope increases, and when the same as the slope value determined in the design, backwashing should be performed.

In design, the depth H _m and the appropriate head loss ΔH of the media 28 are selected in the appropriate range depending on the influent conditions. Although it is possible to design under various conditions, the slope of the backwashing point due to head loss, which is generally applied for site conditions and operation reasons, has the values shown in [Table 1].

Backwashing is performed when the value of the slope obtained from the pressure measurement during operation becomes equal to or larger than the value determined according to [Table 1] during design.

Dual control is possible by utilizing the head loss value ΔH calculated through the pressure gauge 10 and the slope of [Table 1], thereby increasing safety and precision.

)은 변화하지 않기 때문에 단순 수위측정을 통한 제어방식에서 발생하는 노이즈 등의 오류가 발생하지 않아 정밀하고 안정적인 제어를 할 수 있다.In addition, as shown in FIG. 10, when the change (h) of the processing level due to the discharge of backwash water occurs during backwashing or when simply measuring head loss, the measured value temporarily changes, but the slope value (

) Does not change, so errors such as noise generated in the control method through simple water level measurement do not occur, enabling precise and stable control.

As described above, since the water treatment facility operated in a controlled manner is constructed and operated to have two or more biological filters for smooth operation, it must be operated in conjunction with an automatic operation control device for each site.
