The present invention relates to an operation control system and method of a sludge collector, and more specifically, a sludge collector installed in a sewage treatment sedimentation basin to collect sludge on the bottom surface by interlocking control of related products according to the sludge interface system according to the sewage wastewater. And an operation control system and method for a sludge collector for more efficiently performing operation of a water treatment plant.

In general, the water treatment process, such as wastewater flowing out of sewage and industrial plants is treated through a number of stages, such as sedimentation basin, aeration tank. For example, the process of removing the suspended matter in the incoming raw water, and using the activated sludge Decomposition and sedimentation step, and the supernatant water filtered in the sedimentation step is supplied with oxygen from the aeration tank to activate the aerobic bacteria propagation, and the supernatant is separated from the secondary sedimentation basin, and then through the third sedimentation basin or filter paper. The filtered top water is discharged to the stream through the chemical treatment step.

In the water treatment process, sediment is generated during the decomposition and sedimentation of the waste water by using the suspended solids in the raw water and activated sludge.In order to remove the sediment, a sludge collector is essentially installed in the sedimentation basin where the sediment is generated. The sludge collector is divided into a rectangular sludge collector and a circular sludge collector.

The rectangular sludge collector is mainly installed in the initial sedimentation basin and the final sedimentation basin in a relatively medium and large sewage treatment plant, and the circular sludge collector is mainly sludge which collects the sludges of the initial sedimentation basin and the final sedimentation basin in the medium and small sewage treatment plant and concentrates them once more. It will be installed in the sludge collector of the bulk concentrate tank.

Therefore, the rectangular sludge collector installed in the initial sedimentation basin and the final sedimentation basin in the large sewage treatment plant is a chain plate type of a crawler conveyor type, as shown in FIG. 1, and receives infinite rotational power from the drive unit 100. Two rows of chains 110 connected by tracks are connected by three or four axes in the longitudinal direction.

The chain 110 is a hopper in which the sludge in which the flight 111 is settled by the chain 110 rotated along the caterpillar is installed at regular intervals in a direction perpendicular to the length of the sedimentation basin. Will be collected.

The circular sludge collector installed in the concentration tank of the large sewage treatment plant has a peripheral drive type and a central drive type, and the peripheral drive type is divided into a full bridge type and a half bridge type again.

The full bridge type is a method in which two bridges and two drive units rotate around the sedimentation basin, and a lower scraper collects sludge settled at the bottom of the sedimentation basin in the hopper. As the drive unit turns around the sedimentation basin, the lower scraper collects the sludge settled at the bottom of the sedimentation basin in the hopper.

In the center drive type, as shown in FIG. 2, the drive unit 200 is installed at the center of the sedimentation basin, and two scrapers 210 are installed from the drive unit 200 on the bottom surface of the sedimentation basin below the water. It collects the settled sludge in the hopper while rotating.

Here, the drive unit (100) 200 is operated at a speed (0.3 ~ 0.6 m / min) that does not interfere with the settling, the drive unit (100) 200 for the operation to reduce the speed in multiple stages do.

At this time, the deceleration method of the drive unit (100, 200) and the first method to decelerate from the motor to the cyclo reducer; A second method of decelerating from the motor to the cyclo reducer and the worm reducer; Various driving methods are alternatively used, such as the reduction mode from the motor to the micro reducer, flat car, and the bevel gear drive sprocket.

In particular, the rectangular sludge collector may be removed from the sludge collector by scraping sludge from the bottom surface of the sedimentation basin by an endless track chain operated in water, a flight, and a drive unit operated in the water. A plurality of single furnace types such as the first hopper section 112, the second hopper section 113, the third hopper section 114, the fourth hopper section 115, and the like, and the first and second hopper sections It has the form of 1 channel 1 drive type and 2 channel 1 drive type which consists of a number of 3 hopper beams and 4 hopper parts, etc., which will vary the amount of sludge collected. As a result, conditions and deviations are severe depending on the load of sludge, the amount of sludge, and the conditions of the treatment plant.

Thus, the sludge collector has about three times the load fluctuations in the spring, summer, autumn and winter sludge loads, or the daily variation of morning and afternoon, which is not a single sediment but at least two units. Since as many as 50 or more units are installed differently for each treatment plant, the amount of sludge inflow and the degree of sedimentation due to gravity also appear differently depending on the position of the inlet pipe and the amount of sludge settling and loading.

However, the existing sludge interfacial system is supplied with various products such as ultrasonic type or portable type. However, this simply checks the settling amount of each sedimentation basin and performs the linked operation considering the conditions of operation and the location of the type inlet pipe. I can't do it. Therefore, if the operator cannot draw out the sludge due to relying on the operation by the simple timer in a timely manner, the bulking phenomenon that rises due to the sludge decay occurs in the summer when the temperature is high, and the floc occurs in the final settler and discharged into the effluent. It is a situation that causes a problem that adversely affects the treated water quality, or draw the sludge too often to introduce a low concentration of raw water in the reaction tank, causing problems in the subsequent treatment process.

Nevertheless, the sludge collector does not have a way to detect this, so the sludge conveyed in the next step and the load fluctuation due to sedimentation, the wear of the machine occurs, so that the sludge collector operation and sewage treatment There is a problem that causes trouble.

In addition, sludge collectors currently being operated in water purification and sewage treatment plants are operated on a 24-hour basis, so that it is not possible to know how much load is being applied in the water, and the sludge generation amount is spring, summer, In the fall and winter, despite the changes in the morning and afternoon flow rate, they are operating under the same conditions.

In addition, proper measures cannot be established because there is no information on the overload condition caused by foreign substances in the means (chain) to remove sludge from the water during the actual sludge treatment process, or when the overload occurs. The overload can be recognized by the limit switch operating state, which is simply turned on or off by mechanical operation, so that it is impossible to accurately analyze and correct the cause of the occurrence of the overload. The management has to be cumbersome to check and verify the process collection process.

Accordingly, an object of the present invention is to control the interlocking operation of the sludge collector by the sludge interface in conjunction with the sludge collector in the sludge collection process in the sedimentation basin, and to automatically control the raw water inlet gate, sludge drawing valve, sludge drawing pump, etc. Low sludge drawing process reduces sludge treatment process efficiency, maintains the sludge interface high and increases the repair load due to sludge inflow when repair load increases, deteriorates the treated water quality due to injuries due to sludge sludge in the sedimentation basin, and keeps the sludge interface low. The operation control device prevents dehydration efficiency from deteriorating and maintains stable water quality in the sewage treatment plant and detects the sludge interface in the sedimentation basin in a timely manner. By configuring and mounting, the sludge number It is easy to identify the operation status according to the season, time period, sludge settling condition of the equipment, and to respond immediately to the overload that may occur. It is to provide an operation control system and method of the sludge collector which is operated while preventing the wear, failure or damage caused by.

In addition, another object of the present invention is to monitor the operation status from the operation control device at the central control station at any time by connecting to the central control station by the local area network to the operation state controlled by the operation control device of the sludge collector, and the administrator checks from time to time. An object of the present invention is to provide an operation control system and method of a sludge collector that can provide convenience of management without confirmation.

In order to realize the above object, the present invention detects the sludge load state collected from the sludge interface system which is interlocked with the sludge collector which collects the sludge in the sedimentation basin, and compares the detected load state with the set interface height. And an operation control device which determines and starts and stops the relevant device.

The sludge collector described above has about three times the load fluctuations for the load changes such as spring, summer, autumn and winter sludge loads or daily morning and afternoon deviations. Since the sludge inflow rate and the degree of sedimentation due to gravity also vary depending on the pipe condition, the sludge collector is interlocked by the sludge interface system. Automatic operation of the raw water inlet gate installed at the front of the collector allows the sludge volume of each sedimentation basin to be distributed evenly, and the drawing valve and the drawing pump are operated to draw out a certain concentration of sludge in a timely manner. .

Therefore, according to the present invention, the collector installed in the sedimentation basin to collect and process the sediment to control the operation while detecting and controlling the load state acting by the excess sludge and foreign matter during the sludge collection process, the controlled operating state is By transmitting to the central control center for integrated management at the central control center, it is convenient to manage the load fluctuations, and to cope with the overloads that may occur in the future, and to proceed with the work, so that the life of the sludge collector Will be able to extend.

It will be described with respect to the operation control method of the sludge collector of the present invention configured as described above.

First, the operation control device 300 mounted on the drive unit (100) (200) of the sludge collector installed in the sewage treatment sedimentation basin can be installed and operated in an external control box separately from the drive unit (100) (200) in some cases. In addition, the sludge interface setting value of the operation control device and the variable time are set based on the data collected through a predetermined period for each sludge state of the sedimentation basin, for each season, date, and time in advance.

The reason for this is because the characteristics of the treatment device are different for each sedimentation basin, so that the sludge collection operation can be effectively performed only by operating in a suitable operation mode. It can also be backed up by mobile storage as data processed in a way that users can judge, such as charts or graphs.

As an example, the sewage treatment plant is divided into a classification formula and a joining ceremony. The classification formula is widely applied to a new city treatment plant, and sewage and sewage are separated and brought into the treatment plant. It is a way to enter into the treatment plant, the joining method is a method that has been widely applied in the existing urban treatment plant is a method of intermediate treatment through the septic tank in each home or apartment and then brought into the sewage treatment plant. Because of this, there are many differences in the sludge condition of wastewater and sewage, so when operating it in a uniform operation mode, the sludge collector and the reaction tank and the treatment plant, which are the post-stage process, are removed by the load (load) acting according to the amount of sludge. You will not be able to fully function.

Thus, in the operation control device 300, the sludge interface set value minimum load (LL), lower load (L), high load (H), highest load (HH) according to the data collected according to the settling basin in advance And variable time value are set.

The manager sets the set values through the key input unit 303 and the display unit 307 of the operation control device 300, and sets the current date and time in order.

When the operation control device 300 is operated, the control unit 302 or 420 automatically monitors the operation state of the sludge collector, the raw water inlet gate valve, the drawing valve, the drawing pump from the input unit, and the sludge interface system ( 301 receives the periodic control signals of the controllers 302 and 420 to detect and control the load acting on the load due to the sludge and foreign substances in the present sedimentation basin, and the display unit 307 detects the detected load and the operation mode. In addition to the display output box, the maximum value of the detected load in a certain time unit is stored along with the date and time, and the data is transmitted to the central control station or another operation control device. At the same time, the operation mode automatically selects the operation mode from the controllers 302 and 420 according to the interface amount input through the sludge interface 301.

If the interfacial quantity is within the minimum load (LL), it is judged as the first operation mode, the raw water inlet gate is completely opened, the sludge collector is intermittent or stop operation, the drawing valve and the pump are stop operation, and the after process of the treatment plant is stabilized. It reduces power loss and mechanical wear caused by unnecessary operation. In addition, the intermittent operating time of the sludge collector can be adjusted to the plant environment. If the interfacial quantity is within the lowering weight L, the raw water inlet gate is closed by a proportional calculation value, and the sludge collector is operated in a coherent or continuous manner. Even during lowering, the draw valves and draw pumps are stopped to allow more than a certain amount of sludge to collect in the hopper. If the interfacial quantity is at a high load (H), the raw water inlet gate is further closed by a proportional calculation value, and the sludge collector starts the drawing valve and the pump during continuous operation. The drawing valve and the pump are started and stopped for a predetermined time according to the set variable time set value and sludge level. When the interface amount reaches the maximum load HH, the controllers 302 and 420 further close the raw water inlet gate by a proportional calculation value in association with a plurality of sedimentation basins, and the sludge collector continuously operates. The draw valve and pump start and stop for a certain time according to the set time and sludge level. The sludge of each sedimentation basin is opened and closed according to the sludge level measured by the control unit, and the interface of each sludge of each sedimentation basin is equally divided by opening and closing the inlet gate and the pump. In addition to opening and closing the operation of the inlet gate, the sludge drawing valve and the drawing pump installed in the cavity are operated to lower the sludge interface until the sludge interface is detected below the set value. In this case, the sludge interface is automatically changed from the intermittent detection mode to the continuous detection mode. The sludge interface is stored in the memory 305 and the date and time at which the highest HH is measured. The display alerts and notifies the central control station 500.

On the other hand, if the value input from the interface sensor 301 did not reach the maximum load (HH) during the sludge collection operation, independent sludge collection operation is performed without linkage operation with other sedimentation basin. Even in the independent sludge collection operation, the raw water inflow gate is controlled by proportional calculation control and seasonal and hourly data according to the interface amount, so that the sludge interface of each sedimentation battery is equally divided. In addition, even if the interface amount is not the highest load (HH), the maximum value of the detected load by the set time unit is updated with the date and time, stored and displayed, and the sludge collecting operation is performed.

When the interface amount is changed from the interface system 301 and the operation mode is changed, the control unit 302 or 420 stores the interface amount, date, and time in the memory 305 as described above, and displays the display unit 307. The present interface amount is displayed at the same time and the central control station 500 is notified, and the sludge collection operation is continued.

In the operation control apparatus, the looping phenomenon by the comparison operation at the boundary of each operation mode setting value, that is, the sludge interface is changed from the operation mode 1 (LL) to the mode 2 (L), and the sludge collector is driven in the continuous operation mode. The sludge interface is brought back into operation mode 1 (LL) by driving the drawing valve and pump, so that hysteresis, that is, changing from operation mode 1 to operation mode 2, is prevented to prevent the sludge collector from starting and stopping repeatedly. Set the interface set value and the interface set value changed from the operation mode 2 to the operation mode 1 separately to prevent the looping phenomenon.

If excessive inflow water is generated during the sludge operation or the driver sets the operation mode to the emergency operation mode as needed, the operation control device completely opens the raw water inlet gate, the sludge collector is continuously operated, and the drawing valve and the drawing pump are operated by the user. Operation starts with the set start cycle and start time.

The sludge interfacial system 301 installed for the above operation is installed in the center of the sedimentation basin in the case of a circular or located in a predetermined position of the bridge, and in the case of a rectangular shape, the operator installs it in the most proper position even if it is not the hopper part. However, since the operation of the flight 111 or the scraper 210 in the lower sedimentation basin plays an important role of sludge collection, a lift type sludge interface system 301 that does not interfere with operation may be applied. In this case, since the location of the flight 111 or the scraper 210 is most important, a sense such as a proximity switch or a limit switch may be attached to the sensor so that the measurement may be performed after the flight 111 or the scraper 210 passes. Or, if it is close, it is necessary to move up and down.

14 is an example of a remote operation of the sludge collector of the present invention, which includes: an interface system 301 installed in a sedimentation basin for detecting an interface of sludge from sludge collected; An operation control device (300) provided in the interface system (301) for detecting an interface of the sludge according to the operation state of the sludge collector, and controlling the driving with the predetermined operation mode and the load while comparing the determination with the preset operation mode; A LAN 394 for short-range transmission of the data controlled by the operation control device 300; It receives the data transmitted from the LAN (394) is configured as a central control station 500 for controlling the current operating situation.
