[0026] Example 1

[0027] like Figures 1-2 As shown, a pre-sedimentation tank sludge-water separation interface detection system of this embodiment includes a pre-sedimentation tank 1, a camera assembly and a data analysis center 8 installed in the pre-sedimentation tank 1. The pre-sedimentation tank 1 is used to simulate the initial reaction of the sedimentation tank 2, and the pre-sedimentation tank 1 is used as the first dosing point 3 for adding coagulant into the pre-sedimentation tank 1.

[0028] The camera module is used to capture the state of the mud-water separation interface in the pre-sedimentation tank, and the dynamic video from the camera module is sent to the data analysis center.

[0029] Data processing center 8 is used to detect the light transmittance of the mud-water separation interface, and the sedimentation effect in pre-sedimentation tank 1 is judged based on the light transmittance.

[0030] The first injection point 3 is used to adjust the light transmittance by adding coagulant into the pre-sedimentation tank 1.

[0031] In this embodiment, the imaging component continuously captures the state of the mud-water separation interface in the pre-sedimentation tank 1, enabling the data processing center 8 to select the most stable sedimentation state in the pre-sedimentation tank 1 for data analysis. Based on the formation of the mud-water separation interface in the pre-sedimentation tank 1, the data processing center 8 makes a judgment on the addition of coagulant to the first dosing point 3, and then makes an accurate judgment on the addition of coagulant in the subsequent sedimentation tank 2.

[0032] Pre-sedimentation tank 1 is connected to sedimentation tank 2. Sedimentation tank 2 is equipped with a second injection point 4, which is used to add coagulant into sedimentation tank 2.

[0033] The pre-sedimentation tank 1 includes a sedimentation section 11 and a funnel section 12 located below the sedimentation section 11. The sedimentation section 11 is used for the reaction of coagulant and coagulant, and the funnel section 12 is used to receive the precipitate after the reaction.

[0034] The pre-sedimentation tank sludge-water separation interface detection system of this embodiment can effectively detect the coagulation and sedimentation effect in the pre-sedimentation tank, monitor the treatment efficiency of pre-sedimentation tank 1 in real time, and provide accurate basis for continuous adjustment of the coagulant dosage in the next sedimentation tank 2.

[0035] Therefore, this utility model patent aims to provide a detection system and device for the mud-water separation interface in a pre-sedimentation tank. This system and device integrates high-precision sensors, intelligent algorithms, and automated control technology, which can monitor the formation and stability of the mud-water separation interface in real time, provide accurate data support for evaluating the treatment effect of the pre-sedimentation tank, and guide the adjustment of the coagulant dosage in the subsequent sedimentation tank, so as to achieve efficient and stable operation of the water treatment process.

[0036] Example 2

[0037] like Figure 1 As shown, in this embodiment, the sedimentation section 11 is provided with multiple buffer cells 7, which together form an S-shaped slow-flow channel. A first injection point 3 is located at the inlet of the slow-flow channel, and a camera is located at the outlet. This design places the first injection point 3 at the inlet of the slow-flow section, allowing the coagulant injected into the pre-sedimentation tank 1 at the first injection point 3 to react fully with the pre-sedimentation tank 1 along the S-shaped slow-flow channel, thus improving the sedimentation effect of the coagulant. The camera is located at the outlet of the slow-flow channel, enabling the camera to capture the mud-water separation interface after the coagulant has reacted fully in the slow-flow channel, avoiding shooting errors caused by insufficient sedimentation.

[0038] Example 3

[0039] like Figures 1-2 As shown, the shooting components in this embodiment include a camera 5 and a light strip 6. The camera 5 and the light strip 6 are arranged opposite to each other, and the light strip 6 illuminates the camera 5. In this solution, multiple light strips 6 are installed on the side wall of the pre-sedimentation tank 1 and evenly distributed, so that the light strips 6 illuminate the inside of the pre-sedimentation tank 1, enabling the camera 5 to clearly capture the state of the mud-water separation interface when shooting.

[0040] Preferably, the camera 5 is an ultra-wide-angle waterproof area array CCD camera.

[0041] Example 4

[0042] The first injection point 3 includes a first controller 9 and a first coagulant dispenser. The first controller 9 controls the first coagulant dispenser by receiving information from the data processing center 8. The first controller 9 measures and controls the coagulant injected into the pre-sedimentation tank from the first injection point 3, so that the discharge effect in the pre-sedimentation tank 1 can be accurately supported by data.

[0043] The second dispensing point 4 includes a second controller 10 and a second coagulant dispenser. The second controller 10 is electrically connected to the first controller 9. When the light transmittance in the pre-sedimentation tank 1 meets the set value, the second controller 10 controls the second coagulant dispenser through the information from the first controller 9.

[0044] The data processing center 8 of the embodiment accurately captures the dynamic change of the mud-water separation interface through the video taken by the camera 5, and the data processing center 8 calculates the light transmission pixel ratio in the imaging picture to timely reflect the treatment effect of the pre-sedimentation tank 1. Once the mud-water separation interface is formed and kept stable, it indicates that the treatment effect of the pre-sedimentation tank 1 reaches the expectation, and sets a benchmark for the subsequent adjustment of the coagulant dosage in the sedimentation tank 2.

[0045] The data processing center 8 of the embodiment is used for identifying the overall pixel sample and the effective sediment pixel value sample of the mud-water separation interface, and the data processing center calculates the light transmission rate according to the ratio of the effective sediment pixel value sample and the overall pixel sample.

[0046] The effective sediment pixel value of the embodiment is the sample with a pixel greater than 128, and the sample with a pixel value greater than 128 is set as the sample that has completed effective sedimentation.

[0047] The light transmission rate = (the sample with a pixel greater than 128 / the overall pixel sample), and the light transmission rate of 0.2 is set as a reference value in the embodiment.

[0048] If the light transmission rate is greater than 0.2, it indicates that the coagulant dosage of the first dosing point 3 in the pre-sedimentation tank 1 is relatively appropriate, and the sedimentation effect in the pre-sedimentation tank 1 reaches the expectation; at this time, the second dosing point 4 of the sedimentation tank 2 does not need to add coagulant again.

[0049] If the light transmission rate is less than 0.2, it indicates that the coagulant dosage of the first dosing point 3 in the pre-sedimentation tank 1 is insufficient, and the sedimentation effect in the pre-sedimentation tank 1 fails to reach the expectation, and the coagulant needs to be added to the pre-sedimentation tank 1 through the first dosing point 3 until the data processing center 8 detects that the light transmission rate of the pre-sedimentation tank 1 remains above 0.2; at this time, the coagulant dosage of the second dosing point 4 to the sedimentation tank 2 is adjusted according to the coagulant dosage of the first dosing point 3.

[0050] The first dosing point 3 includes a first controller 9 and a first coagulant doser, and the first controller 9 controls the first coagulant doser by receiving the information of the data processing center 8. The coagulant dosed into the pre-sedimentation tank by the first dosing point 3 is controlled by the first controller 9, so that the discharge effect in the pre-sedimentation tank 1 can be accurately supported by data.

[0051] Preferably, the second dosing point 4 includes a second controller 10 and a second coagulant doser, and the second controller 10 is electrically connected to the first controller 9, and when the light transmission rate in the pre-sedimentation tank 1 meets the set value, the second controller 10 controls the second coagulant doser through the information of the first controller 9.

[0052] As shown in the Figure 3 specific process method of the utility model is:

[0053] The dynamic image of the sludge-water separation interface of the pre-sedimentation tank 1 is acquired by the shooting assembly, and the data of the dynamic image is sent to the data processing center.

[0054] The data processing center first identifies the overall pixel samples of the sludge-water separation interface, and then extracts and counts the pixel points with pixel values greater than 128 step by step.

[0055] According to the calculation formula: transmittance = (samples with pixel values greater than 128 / overall pixel samples), the transmittance of the pre-sedimentation tank is calculated.

[0056] The pre-sedimentation tank 1 judges whether the sedimentation effect reaches the expectation according to the transmittance, and controls the dosage of the coagulant added into the pre-sedimentation tank 1 from the first dosing point 3 according to the data feedback of the data processing center 8, so as to control the dosage of the coagulant added into the sedimentation tank 2.

[0057] The above is only an embodiment of the present application, and the well-known specific structures and properties in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
