Biochemical pool sludge state monitoring system and monitoring method

Abstract

The present invention discloses a biochemical pool sludge status monitoring system and monitoring method. The system is installed under a sunshade cover of the biochemical pool, specifically within the pool mouth. The buoyancy block rises or falls with the water level. Since the density of sludge is smaller than that of water, a large amount of sludge floating on the liquid surface will cause the resistance of the pressure sensor on the water-facing side of the pulp plate of the pressure-sensing component to change. At the same time, changes in the density of sewage in the biochemical pool will also cause the resistance of the pressure sensor to change. The system then roughly reflects the changes in water density and floating sludge thickness in the biochemical pool to a controller, thereby achieving automatic monitoring. The present invention solves the problem of inconvenience in detecting water quality and sludge thickness in newly built temporary sewage treatment facilities due to the addition of a sunshade cover.

Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a biochemical pool sludge state monitoring system and a monitoring method thereof. Background Art

[0002] With the continuous development of society, the concentration of population in large cities is becoming increasingly apparent. Existing sewage treatment facilities are no longer able to meet these requirements, necessitating the planning and construction of numerous new sewage treatment plants. Due to limited land resources in large central cities, the choice is often made to relocate existing sewage treatment plants. Typically, temporary sewage treatment facilities are initially established, with the requirement that production, volume, and standards remain unchanged.

[0003] In some newly constructed temporary sewage treatment facilities, sunshades are sometimes installed to prevent algae growth in the biochemical pools. This prevents sunlight from promoting algae growth. However, the addition of sunshades prevents direct observation of the biochemical pools, making it difficult to accurately monitor water quality and sludge thickness, and thus inconvenient to monitor.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] In order to overcome the defects of the existing technology, a biochemical pool sludge status monitoring system and a monitoring method are provided to solve the problem of inconvenience in detecting water quality and sludge thickness in newly built temporary sewage treatment facilities due to the addition of sunshades.

[0006] To achieve the above purpose, a biochemical pool sludge status monitoring system is provided, comprising:

[0007] A support plate is installed at the pool mouth of the biochemical pool, and a plurality of guide columns are connected between the support plate and the pool bottom of the biochemical pool, and the guide columns are slidably provided with buoyancy blocks;

[0008] A distance sensor for collecting the liquid level value of the sewage in the biochemical pool is installed on the support plate;

[0009] A pressure-sensing assembly includes a rotating shaft, a paddle, multiple pressure sensors, and a motor for driving the rotating shaft. The rotating shaft is rotatably mounted on the buoyancy block and is arranged in a horizontal direction. The paddle has a first end and a second end opposite to each other. The first end of the paddle is connected to the rotating shaft. The paddle has a water-facing side and a water-receiving side. The pressure sensor is mounted on the water-facing side. The multiple pressure sensors are spaced apart along the length of the paddle.

[0010] The controller includes a control module, a calculation module and a display module. The control module is connected to the distance sensor, the motor and the pressure sensor. The calculation module and the display module are respectively connected to the control module.

[0011] Furthermore, a receiving groove is formed at the bottom of the buoyancy block, and the rotating shaft is rotatably installed between the opposite side walls of the receiving groove. After the rotating shaft rotates, the paddle plate flips around the central axis of the rotating shaft.

[0012] Furthermore, it also includes a pH sensor for collecting the pH value of sewage in the biochemical pool, and the pH sensor is installed on the buoyancy block.

[0013] Furthermore, the distance sensor is a laser ranging sensor.

[0014] Furthermore, a limit plate is formed at the lower end of the guide column, and the limit plate is arranged below the buoyancy block.

[0015] Furthermore, the support plate is equipped with a spirit level.

[0016] Furthermore, a protection box is set up outside the pool mouth of the biochemical pool, and the display module is installed in the protection box.

[0017] Furthermore, the buoyancy block is an extruded plate.

[0018] The present invention provides a monitoring method for a biochemical pool sludge status monitoring system, comprising the following steps:

[0019] The sewage is injected into the biochemical pool and purified;

[0020] The buoyancy block rises and falls as the liquid level of the sewage rises and falls;

[0021] The distance sensor collects the liquid level value of the sewage;

[0022] The control module of the controller turns on the pressure-sensing component, and the motor of the pressure-sensing component drives the rotating shaft of the pressure-sensing component to cause the paddle plate of the pressure-sensing component to flip around the central axis of the rotating shaft. After the paddle plate flips downward and penetrates below the liquid surface of the sewage, the multiple pressure sensors of the pressure-sensing component collect actual pressure values below the liquid surface of the sewage.

[0023] The control module of the controller obtains the liquid level value and the actual pressure value;

[0024] The calculation module of the controller is preset with a sewage pressure value and a sludge pressure value, and calculates the difference between the actual pressure value and the sewage pressure value and the sludge pressure value;

[0025] After the actual pressure values of some pressure sensors match the sludge pressure value, the control module determines the distance between the first and last pressure sensors in the part of the pressure sensors as the sludge thickness in the sewage and displays it through the display module.

[0026] The beneficial effect of the present invention is that the biochemical pool sludge status monitoring system of the present invention is arranged under the sunshade cover of the biochemical pool, specifically can be arranged in the pool mouth of the biochemical pool, the buoyancy block floats or falls with the water level, because the density of sludge is smaller than that of water, a large amount of sludge floating on the liquid surface will cause the resistance of the pressure sensor on the water-facing side of the pulp plate of the pressure-sensing component to change, and at the same time, the change of sewage density in the biochemical pool will also cause the resistance of the pressure sensor to change, and then roughly reflect the water quality density change of the biochemical pool, the floating thickness of the sludge, etc. to the controller, playing the role of automatic monitoring.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Reference Figures 1 to 6 As shown, the present invention provides a biochemical pool sludge status monitoring system, including: a support plate 1, a distance sensor, a pressure sensing component 2 and a controller 3.

[0037] The support plate 1 is installed at the pool mouth of the biochemical pool. A plurality of guide posts 11 are connected between the support plate 1 and the pool bottom of the biochemical pool. The guide posts 11 are slidably provided with buoyancy blocks 12.

[0038] The distance sensor is installed on the support plate 1. The distance sensor is used to collect the liquid level value of the sewage in the biochemical pool.

[0039] The pressure-sensing assembly 2 includes a rotating shaft 21 , a paddle 22 , a multi-channel pressure sensor, and a motor 23 for driving the rotating shaft 21 .

[0040] For details, see Figure 5 and Figure 6 As shown, a rotating shaft 21 is rotatably mounted on the buoyancy block 12. The rotating shaft 21 is arranged horizontally. A paddle plate 22 has a first end and a second end opposite each other. The first end of the paddle plate 22 is connected to the rotating shaft 21. The paddle plate 22 has a waterfront side and a waterfront side. A pressure sensor is mounted on the waterfront side. Multiple pressure sensors are spaced apart along the length of the paddle plate 22.

[0041] A housing is rotatably mounted at each end of the rotating shaft, and a motor is mounted within the housing. The motor is connected to the rotating shaft in a transmission manner. In some embodiments, the output shaft of the motor is coaxially connected to the rotating shaft. The housing is embedded in a notch at the bottom of the buoyancy block.

[0042] The controller 3 includes a control module, a calculation module and a display module 31. The control module is connected to the distance sensor, the motor 23 and the pressure sensor. The calculation module and the display module 31 are respectively connected to the control module.

[0043] The biochemical pool sludge status monitoring system of the present invention is arranged under the sunshade cover of the biochemical pool, specifically, it can be arranged in the pool mouth of the biochemical pool. The buoyancy block rises or falls with the water level. Since the density of sludge is smaller than that of water, a large amount of sludge floating on the liquid surface will cause the resistance of the pressure sensor on the water-facing side of the pulp plate of the pressure-sensing component to change. At the same time, the change of sewage density in the biochemical pool will also cause the resistance of the pressure sensor to change, and then roughly reflect the water quality density change, sludge floating thickness, etc. of the biochemical pool to the controller, playing the role of automatic monitoring.

[0044] Combine Figure 2 and Figure 3 As shown, a receiving groove is formed at the bottom of the buoyancy block 12. A rotating shaft 21 is rotatably mounted between two opposite side walls of the receiving groove. When the rotating shaft 21 rotates, the paddle 22 turns over around the central axis of the rotating shaft 21.

[0045] As a preferred embodiment, the buoyancy block 12 is an extruded plastic plate.

[0046] The biochemical pool sludge status monitoring system of the present invention further comprises a pH sensor for collecting the pH value of the sewage in the biochemical pool. The pH sensor is installed on the buoyancy block 12.

[0047] As a preferred implementation, the distance sensor is a laser ranging sensor.

[0048] In this embodiment, there are four guide posts, and the lower ends of the guide posts are suspended in the air and not connected to the pool wall.

[0049] The buoyancy block not only can adopt extruded plate, can also by arranging hollow inner cavity to improve buoyancy.In the present embodiment, the buoyancy block floats on the liquid level of the sewage in the biochemical pond all the time.

[0050] The buoyancy block is long and narrow. Guide holes are formed at each end of the block. Two guide posts are movably inserted into the guide holes at each end of the block. As the sewage level in the biochemical pool rises and falls, the buoyancy block rises and falls vertically.

[0051] As a preferred embodiment, a limit plate 111 is formed at the lower end of the guide column 11 . The limit plate 111 is arranged below the buoyancy block 12 .

[0052] As a preferred embodiment, the support plate 1 is installed with a spirit level.

[0053] As a preferred embodiment, a protection box 4 is set up outside the pool mouth of the biochemical pool, and the display module 31 is installed in the protection box 4.

[0054] The present invention provides a monitoring method for a biochemical pool sludge status monitoring system, comprising the following steps:

[0055] S1: The sewage is injected into the biochemical pool and purified.

[0056] S2: The buoyancy block 12 rises and falls as the sewage level rises and falls.

[0057] S3: The distance sensor collects the sewage level value.

[0058] S4: The control module of the controller 3 turns on the pressure-sensing component 2, and the motor 23 of the pressure-sensing component 2 drives the rotating shaft 21 of the pressure-sensing component 2 to make the paddle plate 22 of the pressure-sensing component 2 flip around the central axis of the rotating shaft 21. After the paddle plate 22 flips downward and penetrates below the liquid surface of the sewage, the multiple pressure sensors of the pressure-sensing component 2 collect the actual pressure value below the liquid surface of the sewage.

[0059] S5: The control module of the controller 3 obtains the liquid level value and the actual pressure value.

[0060] S6: The calculation module of the controller 3 is preset with the sewage pressure value and the sludge pressure value, and calculates the difference between the actual pressure value and the sewage pressure value and the sludge pressure value.

[0061] S7 : After the actual pressure values of some of the pressure sensors match the sludge pressure value, the control module determines the distance between the first and last two pressure sensors in the part of the pressure sensors as the sludge thickness in the sewage and displays it through the display module 31 .

[0062] The protective box of the biochemical pool sludge status monitoring system of the present invention is used to protect the display module (ie, the display screen), and a canopy should be provided on the top to keep out rain.

[0063] The display module is used to display data and can also be manually controlled. The data can be transmitted to the central control room via a data cable for remote monitoring.

[0064] The support plate is equipped with a level to ensure horizontality. One side of the support plate is fixed to the wall of the biochemical pool, and the controller is fixed to the support plate by bolts.

[0065] The pressure-sensing component has a built-in motor and is powered by a battery pack. The motor drives the shaft, extending the paddle below the sewage surface. The paddle's sensors, facing different resistance levels in the sewage and sludge, sense the actual pressure and transmit it to the controller for processing.

[0066] The slurry plate will have a resistance when it contacts the liquid surface. The resistance is analyzed in combination with the environment at that time to judge the sludge state in the biochemical pool. The shaft is equipped with two limit rings, and the slurry plate is set between the two limit rings to ensure that the slurry plate is in the middle.

[0067] The distance sensor measures the distance from the liquid surface to the laser rangefinder, which can be converted into the current liquid level height. It is connected to the data processing module and powered by it. The opening and closing of the laser rangefinder is controlled by the display control screen and the central control room.

[0068] When the control module of the controller finds that the resistance data of the pressure sensor on the pulp plate is abnormal, the abnormality can be judged based on the liquid level, sludge thickness, etc.

[0069] In some embodiments, the pH sensor is located at the bottom of the buoyancy block to detect changes in water quality in a timely manner to avoid major sudden changes in water quality that would render the sewage treatment system ineffective and difficult to recover.

Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
