It is particularly pointed out that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only part of the embodiments of the present application, but not all the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

Therefore, the features limited by "first", "second", "third" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or components inherent to the process, method, product or device.

[0025] Reference to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a common or identical embodiment. One of ordinary skill in the art will readily recognize from the disclosure herein, that the embodiments described with the figures can be combined, interchanged or reordered in various ways.

[0026] The field of application of the present application includes wastewater treatment facilities, black and odorous water treatment, tap water and other water treatment fields involving detecting the mud layer in water to guide the sludge discharge amount to adjust the process parameters. The purpose of the present application is to measure the mud height by a direct, effective and portable mud level measuring device to judge the mud-water separation condition and the thickness of the mud layer, to provide a basis for judging the wastewater treatment process operation, to effectively guide the sludge discharge amount and the water surface load adjustment. The accurate measurement of long-term mud level can summarize the effectiveness of the design value of the hydraulic surface load of the radial flow sedimentation tank, master the upper and lower limits of the operating condition, maximize the water capacity of different hydraulic conditions, and improve the utilization rate of the tank body.

[0027] In the field of tap water treatment, for V-shaped sedimentation tanks, inclined tube sedimentation tanks and inclined plate sedimentation tanks, the device of the present application can avoid the areas that cannot be detected by traditional instruments by directly, effectively and portably measuring the mud level, and can provide a basis for judging the process parameters, effectively avoiding data distortion.

[0028] The radial flow sedimentation tank is normally operated continuously. After the wastewater in the previous section is dosed in the flocculation tank, the wastewater will become turbid and be accompanied by a large amount of flocculation flowers, which need to be separated by sedimentation in the next section to remove the flocculation part. The dosed mud water normally enters from the bottom of the tank body, the water overflows from the top of the center cylinder to the inside of the large tank body, the tank body expands the contact area proportion in a large diameter to separate the mud and water, the upper clear water overflows from the water outlet to the next section, and the sedimented mud is discharged from the bottom of the sludge discharge pipe. By continuously discharging mud, the sedimented mud level is kept within a certain range, avoiding the situation that the sedimented mud level is too high to cause the effluent water quality to carry mud.

[0029] In the traditional operation, the mud layer cannot be observed, and only the effluent condition and the hydraulic surface can be observed, supplemented by the sludge discharge concentration judgment, which requires rich experience. At present, in the pulp and paper industry, the discharged wastewater has high concentration, and the operation of the wastewater treatment facility requires high requirements to maximize the function of the facility. Therefore, the wastewater treatment facility is often operated at 90% of the design load. Therefore, the normal monitoring of the mud level is an important auxiliary parameter to improve the stability of the process operation.

[0040] Please refer to Figure 4 , Figure 4 is Figure 1The structure diagram of the mud level measuring device in the embodiment is used for measuring the open pool body. The number 88 in the figure represents the pool body. In the measuring process, the mud level measuring device (with a connecting rod (the first pulling piece 100, hereinafter referred to as the connecting rod) with a total length of about 4.5 m) is carried along the edge of the pool body mud scraper walkway, the mud scraper equipment is stopped, and the length scale value on the connecting rod is recorded; referring to the pool depth (generally 4 meters deep), the mud level is first set to 2 meters, the device is inserted into the pool body at the water surface at the edge of the pool body to 2 meters, the cover 400 is separated from the container bottle 300 through the telescopic rod (the second pulling piece 200, hereinafter referred to as the telescopic rod), and the pool water sample can flow into the container bottle 300; the mud level measuring device is pulled up, and whether the water sample in the bottle contains mud is observed. If a small amount of mud is contained, the mud level is 2 meters. If a large amount of turbid sludge is contained, the mud level is higher than 2 meters, and the insertion height of the mud level measuring device needs to be reduced for re-measurement. If no mud is contained, the mud level is lower than 2 meters, and the insertion height of the mud level measuring device needs to be increased for re-measurement. Such re-measurement is performed 2-3 times, so that the accurate mud level can be determined. The on-site measurement conforms to the real-time working condition of operation, and the operation personnel can often determine the accurate value in one time, thereby reducing the re-measurement times.

[0041] For the sealed pool body, the second soft connection type mud level measuring device is made, which is used for measuring the narrow area and can also be used for measuring the open pool body.

[0042] Please refer to Figure 5 and Figure 6 , Figure 5 is the structure diagram of the cover of the mud level measuring device in another embodiment of the application being combined with the bottle opening of the container bottle, Figure 6 is Figure 5 the structure diagram of the cover opening the bottle opening of the container bottle of the mud level measuring device in the embodiment. The mud level measuring device in the embodiment can also include but is not limited to the following structures: the first pulling piece 100, the second pulling piece 200, the container bottle 300, and the cover 400.

[0043] Different from the foregoing embodiments, the first pulling piece 100 and the second pulling piece 200 in the embodiment can be rope structures. One end of the first pulling piece 100 is connected with the outer side wall of the container bottle 300, and specifically can be connected with the handle 310 on the container bottle 300. One end of the second pulling piece is connected with the cover 400.

[0044] The container bottle 300 in the embodiment can be made of metal or alloy (e.g., stainless steel), and can be completely immersed in the sludge under the action of gravity when the container bottle 300 is sealed. Alternatively, the container bottle 300 in the embodiment is made of stainless steel, which can prevent corrosion and ensure the weight. For example, in an embodiment, the container bottle 300 can have a height of 230 mm, a 10 mm wide flat steel lifting ring (handle 310, facilitating extension and retraction), a diameter of 60 mm, an inner width of the upper opening of 30 mm, a thickness of about 5 mm, and a weight of more than 1000 g. The cover 400 can also be made of stainless steel, with an upper edge protruding by 2 mm, a lower edge consistent with the inner diameter of the bottle opening (about 30 mm wide, facilitating plugging), and a height of about 25 mm. The first lifting member 100 and the second lifting member 200 can be made of polyethylene rope, which is flexible and light and easy to fold.

[0045] Please refer to Figure 7 , Figure 7 is Figure 5 The structure diagram of the use state of the sludge level measuring device in the embodiment is shown in the figure. The sludge level measuring device in the embodiment is suitable for measuring all pool bodies, especially narrow spaces and covered pool bodies. In the figure, 88 represents a pool body, and 881 represents a pool cover. During measurement, the sludge level measuring device is carried to the edge of the pool body mud scraper walkway, and the mud scraper equipment is stopped. Referring to the pool depth (generally 4 meters deep), the sludge level is first set to 2 meters, and the device is immersed in the pool body to a depth of 2 meters at the water surface. The cover is pulled open with a rope (the second lifting member 200), and the pool water sample flows into the container bottle. The sludge level measuring device is pulled up, and it is observed whether the water sample in the bottle contains mud. If a small amount of mud is contained, the sludge level is 2 meters. If a large amount of turbid sludge is contained, the sludge level is higher than 2 meters, and the sludge level measuring device needs to be lowered to measure again. If no mud is contained, the sludge level is lower than 2 meters, and the sludge level measuring device needs to be increased to measure again. Such repeated measurements are performed 2-3 times to determine the accurate sludge level. The on-site measurement conforms to the real-time operating conditions, and the operating personnel can often determine the accurate value in one measurement, reducing the number of repeated measurements.

[0046] Compared with the traditional sludge discharge method, the accurate sludge level is measured by the sludge level measuring device, which is more accurate for on-site operation guidance. The present application has the following advantages:

[0047] 1. Precise numerical data guides process operation. Traditional sludge removal from sedimentation tanks involves periodic bottom-volume sludge removal. Sludge removal efficiency can only be judged by sludge concentration and the condition of the upper effluent, but it cannot predict the height of the sedimentation sludge layer within the sedimentation tank, nor can it understand the floc settling situation after wastewater chemical treatment and the guiding role of sludge removal volume in operation. With a sludge level measuring device, the water flow load and sludge removal status can be determined by monitoring the sludge level in the sedimentation tank in real time, making sludge removal more efficient and targeted, improving the operating efficiency of the sludge removal pump, and reducing pump operating time by 2 hours / day.

[0048] 2. Accurately determine the actual flow load of the sedimentation tank. Through long-term sludge level measurement, based on the hydraulic surface design values ​​of the sedimentation tank, the actual hydraulic surface load of the sedimentation tank is determined to maximize the tank's efficiency. In addition, the sedimentation tank's design capacity for treating different water qualities is monitored simultaneously, providing first-hand data for operational and design guidance.

[0049] 3. Reduced chemical consumption in the later stages. Sludge level monitoring provides data support for the growth period, ensuring stable production operation. Operational data shows that in 2024, the SS in the AO tank influent decreased to <50mg / l, a 37.5% reduction compared to when sludge level was not monitored (80mg / l), improving the removal efficiency of the biological treatment tank by 3%. Based on a primary sedimentation tank effluent COD of 900mg / l, a 3% increase in removal efficiency can reduce COD by 30mg / l, reducing the dosage of advanced water treatment chemicals by 0.05kg / m³. 3 .

[0050] 4. Reduce biological sludge production. Sludge level measurement guides the sludge discharge time and volume in different sedimentation tanks, improving effluent quality, reducing SS in the downstream effluent by approximately 30 mg / L, and reducing the sludge discharge volume of the biological system by 2100 kg / day (based on a treatment capacity of 70,000 cubic meters / day).

[0051] The mud level measuring device provided in this application embodiment can determine the mud-water separation status by physically measuring the mud level height in real time, providing a basis for judgment on process operation. The mud level measuring device has the characteristics of simple structure and convenient operation.
