[0002] Sedimentation tank is an important part of water plant to remove suspended solids. Through gravity, solid particles in sewage are settled to the bottom. Sludge interface meter monitors and controls the mud level of sedimentation tank, and determines the mud discharge cycle of sedimentation tank and whether it can operate stably online. Accurate mud level data directly affects the operation of water purification plant and sewage treatment plant, and can effectively reduce impurities in water and reduce the impact of sludge on water quality.

[0003] In the related technology, conventional sludge interface meters realize real-time monitoring of sludge thickness changes and control of related process by detecting the distance between the sensor probe and the sludge interface and the bottom surface.

[0057] Below is a combination of the embodiments and Figure 1-Figure 3 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0058] The present invention discloses a multi-point measurement and real-time monitoring sludge interface instrument, which specifically comprises:

[0059] The data monitoring module 1 is used to monitor the relevant parameters of the sludge and store them as sludge data.

[0060] The data transmission module 2 is electrically connected to the data monitoring module 1 and is used for receiving and transmitting the sludge data.

[0061] The data transmission module 2 includes a base station and a solar cell group, which are linearly connected, and transmits data to the data analysis module 3 in a wireless manner through the base station.

[0062] The data analysis module 3 is signal-connected to the data transmission module 2, and is used to receive the sludge data transmitted by the data transmission module 2, analyze whether sludge discharge is required, and output the analysis result.

[0063] The control module 4 is connected to the data analysis module 3 by signals, and is used to receive the analysis results and control the mud discharge device to discharge mud according to the analysis results.

[0064] A large amount of sludge is generated by sedimentation in the water plant, and a sludge discharge device is required for sludge discharge. When the analysis result received by the control module 4 indicates that sludge discharge is required, the control module 4 turns on the switch of the sludge discharge device and starts the sludge discharge device for sludge discharge.

[0065] The mobile module 5 is connected to the data monitoring module 1 by signal, and is used to move the data monitoring module 1 to perform multi-point monitoring in the sedimentation tank and output a mobile signal.

[0066] The data analysis module 3 includes a height component 31, a concentration component 32, a flatness component 33 and a time component 34. The height component 31 is connected to the data transmission module 2 by signal, and is used to receive sludge data and analyze whether the height meets the sludge discharge requirements, and output the height result. The concentration component 32 is connected to the height component 31 by signal, and is used to receive the height result and analyze whether the concentration meets the sludge discharge requirements, and output the concentration result. The flatness component 33 is connected to the height component 31 and the concentration component 32 by signal, and is used to receive the height result, the concentration result and analyze whether the flatness meets the sludge discharge requirements, and output the flatness result. The time component 34 is connected to the height component 31, the concentration component 32, and the flatness component 33 by signal, and is used to receive the height result, the concentration result and the flatness result and analyze the sludge discharge time, and output the analysis result.

[0067] If the result received by the time component 34 is that mud discharge is not required, the analysis result is that mud discharge is not required. If the result received is that mud discharge is required, the mud discharge time is calculated according to the average height, and the analysis result is the specific time of mud discharge.

[0068] In actual use, a large amount of sludge will be produced in the sedimentation process of the water plant. The discharge of sludge will not only affect the sedimentation process of the water plant, but also affect the effluent quality. If the sludge is discharged only when the sludge reserves reach the threshold, the effluent quality will be poor in certain periods, and the water after sedimentation cannot be used, resulting in a waste of water resources. At the same time, fixing the sludge interface meter at a certain location for monitoring cannot achieve the effect of monitoring the entire sedimentation tank, resulting in errors in the sludge discharge time. For example, the sludge height at the fixed position of the sludge interface meter is low, but in fact the sludge at other positions in the sedimentation tank has reached the height threshold, and the sludge reserves also exceed the threshold. At this time, the sludge interface meter gives a result that sludge discharge is not required based on the height data of a single position, and the judgment is wrong, which affects the subsequent water discharge. Therefore, comprehensive monitoring of the sedimentation tank at multiple points can improve the accuracy of real-time sludge monitoring.

[0069] The data monitoring module 1 includes a data acquisition component 11 , an environment monitoring component 12 and a sludge monitoring component 13 .

[0070] The data acquisition component 11 is connected to the water inlet system signal and is used to extract the water inlet data of the water inlet system. The water inlet data includes water flow, water flow rate, water inlet temperature and impurity content.

[0071] The data acquisition component 11 is configured as an LED touch screen to collect water flow and water flow rate set by the user, and also includes a water quality detector to intercept a small portion of water for detection to obtain water inlet temperature and impurity content.

[0072] The environmental monitoring component 12 includes a temperature sensor 121 and a pH sensor 122. The temperature sensor 121 is used to monitor the temperature of the sludge and output the sludge temperature. The pH sensor 122 is used to monitor the pH value of the sludge and output the pH value of the sludge.

[0073] The sludge monitoring component 13 is electrically connected to the data acquisition component 11 and the environmental monitoring component 12, and is used to receive water inlet data, sludge temperature and sludge pH value, select a position in the sedimentation tank to perform sludge monitoring and output sludge data.

[0074] In actual use, during the precipitation process, the actual precipitation effect of water is affected by many factors. If the water flow rate is too fast, some light impurities will not be precipitated at the outlet. The precipitation effect of different impurity contents is also different. Temperature and pH value will also affect precipitation, because the increase in temperature can increase the movement speed of ions or molecules, increase the frequency of collisions between them, thereby increasing the possibility of reaction and changing the precipitation rate. The pH value of the solution can affect the solubility of the precipitate, because the change in pH value can change the existence form and charge state of ions in the solution, thereby affecting the stability and solubility of the precipitate. The change in pH value will also affect the speed of the precipitation reaction. When the pH value of the solution is close to the isoelectric point of the precipitate, the speed of the precipitation reaction will slow down, because the charge state on the surface of the precipitate at this time will affect the interaction between ions. Therefore, judging whether sludge discharge is needed based on the actual precipitation effect greatly improves the quality of the effluent water.

[0075] The sludge monitoring component 13 includes a position unit 131 and a monitoring unit 132. The position unit 131 is electrically connected to the data acquisition component 11 and the environmental monitoring component 12, and is used to receive water inlet data, sludge temperature and sludge pH value, and determine the monitoring position in the sedimentation tank and output the monitoring position. The monitoring unit 132 includes a radar level sensor 1321, an optical sludge sensor 1322 and a memory 1323. The radar level sensor 1321 is used to monitor the sludge height and output the sludge height data. The optical sludge sensor 1322 is used to monitor the sludge concentration and output the sludge concentration data. The memory 1323 is electrically connected to the radar level sensor 1321 and the optical sludge sensor 1322, and is used to receive the sludge height data and the sludge concentration data. The memory 1323 is connected to the mobile module 5 signal, and is used to receive the mobile signal and store the sludge height data and the sludge concentration data when the mobile signal is received.

[0076] In actual use, the radar level sensor 1321 transmits and receives very short microwave pulses with very low energy through the antenna system. These pulses propagate in space at the speed of light. When encountering the surface of the sludge to be measured, part of the pulse energy is reflected back and received on the same line, thereby detecting the height of the sludge. Through the optical scattering phenomenon, the light will be scattered in different directions. The optical sludge sensor 1322 can receive these scattered lights in different directions and convert them into electrical signals. By measuring the scattering angle and scattering intensity of these lights, the concentration of the sludge can be calculated. By monitoring the sludge height and sludge concentration, a strong basis is provided for the obtained sludge discharge results, which is more in line with the actual situation. And when the mobile signal is received, the data is stored to reduce the interference of useless data.

[0077] The location unit 131 includes a fluctuation subunit 1311 , a temperature subunit 1312 , a PH subunit 1313 , and a location subunit 1314 .

[0078] The location unit 131 is configured as a computer chip to analyze fluctuation conditions, temperature conditions, pH conditions, and location conditions.

[0079] The fluctuation subunit 1311 is connected to the data acquisition component 11 by signal, and is used to receive water inlet data, obtain the sedimentation tank plan, extract the water inlet position of the sedimentation tank, set the distance interval, divide the area according to the distance interval and the water inlet position, and output the regional plan. According to the regional plan, the sewage fluctuation degree of different areas is obtained in combination with the water flow rate and water flow rate, and the regional fluctuation data is output.

[0080] The temperature subunit 1312 is signal-connected to the data acquisition component 11 and the environmental monitoring component 12, and is used to receive the inlet water temperature and the sludge temperature, and obtain the temperature values ​​of different areas by combining the inlet water temperature and the sludge temperature and output the area temperature data.

[0081] The PH subunit 1313 is signal-connected to the data acquisition component 11 and the environmental monitoring component 12, and is used to receive the impurity content and the sludge PH value, determine the PH value of different areas and output the regional PH value data.

[0082] The position subunit 1314 is signal-connected to the fluctuation subunit 1311, the temperature subunit 1312, and the PH subunit 1313, and is used to receive regional fluctuation data, regional temperature data, and regional PH value data, set the positioning weight ratio of the regional fluctuation data, regional temperature data, and regional PH value data, and calculate the height anomaly values ​​of different regions. Set the height anomaly threshold, and select the area that reaches the height anomaly threshold as the monitoring position.

[0083] According to the difference between the regional fluctuation data, regional temperature data, regional PH data and the fluctuation data, temperature data and PH data under the ideal state, the corresponding positioning weight ratio is set to calculate the height abnormal value. For example, the regional fluctuation data, regional temperature data, and regional PH data are 1 cm wavelength, 10 degrees Celsius, and PH value 8 respectively, and the ideal state is 0 wavelength, 20 degrees Celsius, and PH value 7. The corresponding positioning weight ratio is 1:2:2, and the calculated height abnormal value result is (1-0)×20%+(20-10)×40%+(8-7)×40%=4.6.

[0084] In actual use, temperature, pH value and water flow rate will affect the precipitation of impurities, resulting in different sludge heights in different areas. If the water flow rate is too high, the sludge at the water inlet will be impacted by the water flow at a high speed, resulting in lower sludge at the water inlet. The temperature of the sludge in the sedimentation tank is affected by the external environment and will be different from the temperature of the water inlet, which will cause the temperature in different areas to be different. For example, if the temperature in the sedimentation tank is 30 degrees Celsius and the inlet temperature is 10 degrees Celsius, the water temperature near the water inlet will be lower and the temperature far away from the water inlet will be higher. Depending on the precipitation situation, the pH value in different areas will also be different. If the difference is not large, the height difference of the precipitated sludge will not be large, and the average height can be used as the sludge height. If the difference is too large, it is necessary to detect the sludge height in the area to reduce the excessive sludge height in a certain area, forming sludge accumulation, hindering the further precipitation of water flow and suspended matter, and causing the effluent water quality to fail to meet the standard. Monitoring is performed at multiple points, and highly abnormal areas are selected for monitoring based on water flow velocity, temperature, and pH value. This can reduce useless data interfering with analysis on the one hand, and reduce the frequent movement of the mobile device 51 on the other hand, thereby reducing the interference of monitoring on sedimentation.

[0085] It is used to receive the impurity content and sludge pH value, determine the pH value of different areas and output the regional pH value data, specifically:

[0086] Obtain the weight of sewage, obtain the weight of different impurities according to the impurity content, combine the weight of different impurities and water flow rate, predict the impurity content in different areas and obtain the regional impurity content.

[0087] The pH values ​​of different impurities in the sewage are obtained. According to the regional impurity content and sludge pH value, the pH values ​​of different regions are calculated and recorded as regional pH value data.

[0088] In actual use, different impurities have different pH values ​​and different precipitation speeds, so the pH values ​​in different areas will change during the precipitation process. For example, sediments such as sand, gravel, and heavy metals are heavier and less susceptible to water flow, so they are more likely to settle near the water inlet. Some tiny particles and colloids suspended in the water are easily evenly distributed in the entire sedimentation tank under the action of water flow. Therefore, the pH value of the area near the outlet needs to be combined with the properties of sediments such as sand, gravel, and heavy metals, and the pH value will be different. Because of the different weights of impurities, the distribution areas of different impurities can be predicted according to the water flow rate, thereby obtaining the pH values ​​of different areas.

[0089] The height component 31 includes a height determination unit 311 and a height change unit 312 .

[0090] The height determination unit 311 is connected to the data transmission module 2 by signals, and is used to receive sludge height data, set a sludge height threshold, and determine whether the sludge height reaches the sludge height threshold.

[0091] For the received sludge height data, determine whether there is an area whose height reaches the sludge height threshold. If so, the sludge needs to be discharged in time, because the sludge height in the area will continue to rise and affect the effluent water quality.

[0092] If the sludge height reaches the sludge height threshold, the output height result is that sludge discharge is required.

[0093] If the sludge height does not reach the sludge height threshold, a change signal is output to the height change unit 312 .

[0094] The height change unit 312 is signal-connected with the height judgment unit 311 and the data transmission module 2, and is used to receive the change signal, and after receiving the change signal, set the standard environment to obtain the standard precipitation speed of impurities under the standard environment.

[0095] Obtain the properties of impurities, combine the sludge temperature and sludge pH value, and obtain the actual sedimentation rate based on the standard sedimentation rate.

[0096] The actual sedimentation rate is obtained by combining the influence curve based on the difference between the sludge temperature and the standard temperature, and the difference between the sludge pH value and the standard pH value. The influence curve is formed by setting the sedimentation rate corresponding to the temperature and pH value. For example, the standard ambient temperature is 25 degrees Celsius, the sedimentation rate of impurity A is 1 cm / s, and the actual temperature is detected to be 10 degrees Celsius. The corresponding actual sedimentation rate of impurity A decreases due to the temperature drop and becomes 0.5 cm / s.

[0097] According to the actual sedimentation rate and water flow rate, it is determined whether mud discharge is needed. If mud discharge is needed, the output height result is that mud discharge is needed.

[0098] If mud discharge is not required, the output height result is that mud discharge is not required.

[0099] In actual use, if the sludge reaches the height threshold, it is undoubtedly necessary to discharge the sludge. If the height does not reach the threshold, it does not mean that the sludge does not need to be discharged. Due to the influence of factors such as temperature and pH value, the sedimentation rate of some sediments slows down. In fact, the height of the sludge has reached the sludge threshold after precipitation. For example, according to the actual sedimentation rate, the sludge height reaches the threshold after one hour. After the sludge height reaches the threshold, the sedimentation tank can only accommodate 10 cubic meters of water. During this hour, according to the water flow, 15 cubic meters of water is required. Obviously, in this process, the capacity is insufficient and the sludge needs to be discharged in time. At the same time, the sludge has reached the height threshold, which means that the sludge has reached the threshold amount, which will cause the effluent water quality to deteriorate and the sludge needs to be discharged in time.

[0100] The concentration component 32 is connected to the height component 31 by signal, and is used to receive the height result. If the height result indicates that mud discharge is required, the concentration result is directly output, and the concentration result indicates that mud discharge is required.

[0101] The concentration component 32 is connected to the data transmission module 2 signal and is used to receive sludge concentration data. If the height result is that sludge discharge is not required, the sludge concentration of the existing monitoring positions is counted, and a sludge concentration threshold is set to determine whether the sludge concentration reaches the sludge concentration threshold. If the sludge concentration reaches the sludge concentration threshold, the concentration result is that sludge discharge is required.

[0102] If no sludge concentration reaches the concentration threshold, the difference of all sludge concentrations is calculated and recorded as the concentration difference, and the concentration difference threshold is set to determine whether the concentration difference reaches the concentration difference threshold. If the concentration difference reaches the concentration difference threshold, the concentration result is that sludge discharge is required.

[0103] If the concentration difference does not reach the concentration difference threshold, the concentration result is that sludge discharge is not required.

[0104] In actual application, if the sludge height has reached the threshold and the sludge discharge result is given, no subsequent analysis is required. If the sludge height does not reach the threshold, it is necessary to analyze whether sludge discharge is required based on the sludge concentration. Sometimes, although the sludge does not reach the height threshold, the sludge concentration is high, which will still lead to poor effluent quality, so sludge discharge is also required. When the sludge concentration is too high, the spacing between sludge particles decreases, and a tight sludge layer is easily formed. This will lead to a decrease in sedimentation efficiency because it is difficult for newly entering suspended particles to find enough space to settle in the already formed sludge layer. By discharging sludge, the sludge concentration in the sedimentation tank can be reduced, the sedimentation capacity of the sedimentation tank can be restored, and the effluent water quality can be ensured to meet the design requirements. When the sedimentation concentration in different areas of the sedimentation tank is inconsistent, it will cause excessive sediment accumulation in some areas, while relatively less in other areas. In this case, the overall sedimentation efficiency will be affected because the denser areas may be blocked due to the rapid accumulation of sediment, while the thinner areas cannot fully utilize their sedimentation capacity.

[0105] The flatness component 33 is signal-connected to the height component 31 and the concentration component 32, and is used to receive the height result and the concentration result, and determine whether any of the height result and the concentration result indicates that mud discharge is required.

[0106] If there is a result that mud removal is required, the flatness result will be directly output as requiring mud removal.

[0107] The flatness component 33 is connected to the data transmission module 2 for receiving sludge height data. If there is no result indicating that sludge discharge is required, the average sludge height is estimated based on the sewage weight and impurity content.

[0108] According to the sludge height data, the sludge height in the unmonitored area is set as the average sludge height, and combined with the sludge height in the existing monitored area to form a sludge height simulation diagram.

[0109] According to the sludge height simulation diagram, a height change curve is drawn to obtain the curve change angle, and the sludge flatness is obtained according to the curve change angle.

[0110] Calculate the average value of the curve change angle. The larger the average value of the change angle, the lower the sludge flatness.

[0111] Set the sludge flatness threshold to determine whether the sludge flatness reaches the sludge flatness threshold. If the sludge flatness does not reach the sludge flatness threshold, the output flatness result is that sludge discharge is required.

[0112] If the sludge flatness reaches the sludge flatness threshold, the output flatness result is that sludge discharge is not required.

[0113] In actual use, the flatness of the sedimentation tank is directly related to the sedimentation effect of sludge particles in sewage. A sedimentation tank with good flatness can ensure uniform distribution of water flow, avoid short-flow and dead corners, and thus improve the sedimentation efficiency of sludge particles. A sedimentation tank with poor flatness will cause sludge to accumulate in local areas and form a sludge layer. These accumulated sludge layers will not only affect the sedimentation effect, but also block the sludge discharge pipe and reduce the sludge discharge efficiency. Therefore, when the flatness is not high, it is also necessary to discharge the sludge in time to avoid affecting the effluent water quality. For example, if it is not necessary to discharge sludge based on the height and concentration, a height change curve is formed according to the sludge height monitored at each point. The larger the angle of the curve, the greater the height difference and the lower the sludge flatness. When the sludge flatness is lower than the threshold, it is necessary to discharge the sludge in time to reduce the impact on the effluent water quality.

[0115] In actual use, the mobile device 51 can move the monitoring module to achieve multi-point monitoring and obtain monitoring data at different positions of the sedimentation tank.

[0116] The mobile assembly 52 includes a positioning unit 521, a central axis 512 controller and a slide rail 514 controller.

[0117] The central axis 512 controller is connected to the positioning unit 521 by signal, and is electrically connected to the central axis 512 .

[0118] The monitoring coordinates are connected to the origin to obtain a straight line passing through the origin and recorded as the target straight line. The central axis 512 controller controls the central axis 512 to rotate until the slide rail 514 coincides with the target straight line and the monitoring target is located below the slide rail 514 and outputs a first movement signal.

[0119] The slide rail 514 controller is signal-connected to the central axis 512 controller and the data monitoring module 1 , and is used to receive the first movement signal, and control the data monitoring module 1 to the monitoring position and then output the movement signal to the memory 1323 .

[0120] In actual use, the controller controls the rotation of the central axis 512 and the movement of the slide rail 514, so that the monitoring module can monitor the sludge data at any position of the sedimentation tank, achieve the effect of global monitoring of the sedimentation tank, and improve the accuracy and comprehensiveness of the sludge interface instrument.
