[0024] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0025] Example 1

[0026] The total phosphorus variation trend detection device in the wastewater treatment system of this embodiment, such as... Figure 2 As shown, the system includes an outer shell 16, a reaction vessel 10 installed inside the outer shell 16, and a cloud server 8 and a cloud platform outside the outer shell 16. An image acquisition system is installed on the front side of the reaction vessel 10, and an LED light panel 6 is installed on the rear side. The image acquisition system preferably uses a camera 9, which continuously records visual data in the reaction vessel 10 and uploads it to the cloud server 8. After preprocessing the visual data, the cloud server 8 inputs it to the cloud platform, where a neural network model detects the trend of total phosphorus concentration change.

[0027] The total phosphorus change trend detection device in the wastewater treatment system of this embodiment uses visual data including image information of the process of total phosphorus in wastewater reacting with coagulants and coagulants to produce flocs. The process of total phosphorus reacting with coagulants and coagulants to produce flocs is observed and recorded by camera 9, including the speed, size and settling speed of flocs. The neural network model quickly analyzes the changes in total phosphorus concentration in wastewater and obtains the relationship between floc image information and total phosphorus concentration to detect the trend of total phosphorus concentration change. This reduces the dependence on manual resources, shortens the total phosphorus detection time and improves the real-time performance of total phosphorus detection.

[0028] Example 2

[0029] The total phosphorus change trend detection device in the wastewater treatment system of this embodiment has the same basic structure as that in Embodiment 1, with the following differences or improvements: the LED light panel 6 automatically adjusts the LED array according to the brightness of the mixed solution in the reaction vessel 10, thereby improving the timeliness and accuracy of the camera 9 in continuously recording visual data in the reaction vessel 10. A vertical acrylic plate 18 is also installed between the reaction vessel 10 and the LED light panel 6, preferably an opaque acrylic plate 18, to avoid the LED array brightness being too concentrated and affecting the acquisition of visual data of alum floc. The reaction vessel 10 has a built-in stirring device 20, which includes a motor and stirring blades. The stirring blades are vertically installed in the middle of the reaction vessel 10 to facilitate the full reaction of the mixed solution to produce alum floc and to disperse the alum floc to obtain the input image data required for detection; the stirring method can also adopt other forms such as a magnetic stirrer. A cleaning device 21 is also installed on the inner wall of the reaction vessel 10 facing the camera 9. Wastewater contains suspended solids, and the reaction mixture contains flocculent matter, which will adhere to the inner wall of the reaction vessel. If the vessel is not cleaned before the next reaction, the video and image data collected by the camera will be blurry, affecting subsequent data analysis and processing. The cleaning device is a brush or scraper lift, driven by a motor to remove residual flocculent matter from the reaction mixture.

[0030] Example 3

[0031] The total phosphorus variation trend detection device in the wastewater treatment system of this embodiment has the same basic structure as in Embodiment 2, such as... Figure 1 , 2As shown, it includes a coagulant tank 2 and a coagulant aid tank 5 for supplying coagulant and coagulant aid respectively, as well as a microcontroller 3, a cloud server 8, a camera 9, a clean water tank 13, a wastewater tank 15, an outer shell 16, and a reaction vessel 10 inside the outer shell 16 for mixing wastewater, coagulant, and coagulant aid. Wastewater tank 15, coagulant tank 2, coagulant aid tank 5, and clean water tank 13 are all connected to the reaction vessel 10 via external pipes and pumps. The pumps are wastewater pump 14, coagulant dosing pump 1, coagulant aid dosing pump 4, and clean water pump 12, respectively. A weight sensor is installed at the bottom of the coagulant aid tank 5 to facilitate control of the amount of coagulant added. The bottom of the reaction vessel 10 is equipped with a drain outlet and a drain valve 11 to discharge the cleaning water and the mixed liquid after the reaction. An LED light panel 6 is installed at the rear to control the brightness of the background light during the data acquisition process, which facilitates data acquisition. A stirring device 20 is installed inside the reaction vessel 10 to fully stir the mixture and break up the settled flocs into flocs. The reaction vessel 10 and the camera 9 are both built into the outer shell 16 to isolate the external brightness of the device from the visual data analysis. The microcontroller 3 connects to the power supply and various parts of the device, such as the pump, LED lights, stirring device 20, drain valve 11, and cloud server 8, to automatically collect image and video data of the reaction between total phosphorus in wastewater and coagulant and coagulant aid to produce flocs; the camera 9 is connected to the cloud platform via a data cable and can also be connected wirelessly, and is located in front of the reaction container 10; the coagulant tank 2, coagulant aid tank 5, clear water tank 13, and wastewater tank 15 are all connected to the reaction container 10 via pumps and pipes, which facilitates the addition of the corresponding liquids to the reaction container 10 according to the controlled dosage.

[0032] A cleaning device 20 is installed inside the reaction vessel 10. Wastewater containing suspended solids and flocculent matter in the reaction mixture will adhere to the inner wall of the reaction vessel 10. If the vessel is not cleaned before the next reaction, the video and image data captured by the camera 9 will be blurry, affecting subsequent data analysis and processing. The cleaning device 20 is a brush or scraper lift, driven by a motor to remove residual flocculent matter from the reaction mixture.

[0033] An LED light panel 6 and an opaque acrylic plate 18 are installed at the rear of the reaction vessel 10. The LED light panel 6 is an LED array of the same size as the rear of the reaction vessel 10. During the reaction, it is necessary to illuminate the rear of the reaction vessel 10 to see the state of the floc formation. Different wastewater contains different levels of suspended solids. The LED array is set to automatically adjust according to the brightness of the mixed solution. The acrylic plate 18 is located between the LED light panel 6 and the reaction vessel 10 to avoid the brightness of the LED array being too concentrated and affecting the visual data of the floc formation.

[0034] The stirring device 20 includes a motor and a stirring blade. It is covered above the reaction vessel 10 and the stirring blade is installed in the center of the reaction vessel 10 to facilitate the full reaction of the mixed solution to produce flocs and to disperse the flocs, so as to obtain the input image data required for detection.

[0035] The coagulant storage system includes a coagulant tank 5, a coagulant powder box 7, and a weight sensor. The coagulant tank 5 is located below the coagulant powder box 7, and the weight sensor is located at the bottom of the coagulant tank 5. Because the coagulant is prone to sedimentation after being prepared into a solution, directly adding the coagulant solution to the reaction vessel 10 using a dosing pump would result in inaccurate coagulant concentration. Therefore, a weight sensor is used to sense the amount of coagulant added, and a water pump is used to add an appropriate amount of clean water to the coagulant tank 5. A stirring device is used to agitate the solution and prevent sedimentation, ensuring the uniformity and accuracy of the coagulant concentration.

[0036] Camera 9 uploads the collected visual data of alum floc to cloud server 8. After preprocessing the visual data, cloud server 8 inputs the data into a neural network model on the cloud platform to detect the trend of total phosphorus concentration changes. After the detection results are generated, cloud server 8 feeds the analysis results back to the monitoring platform. Simultaneously, all visual data and detection results are stored in the cloud database for subsequent review and analysis. Furthermore, the cloud platform's neural network model can be regularly updated and optimized through database updates to ensure its detection accuracy and performance remain at their best.

[0037] The total phosphorus change trend detection device in the wastewater treatment system of this embodiment uses pumps, drain valves, weight sensors, stirring devices, image acquisition systems, etc. to automatically collect data on the reaction process from the formation of floc to sedimentation of wastewater according to the process and given dosage. It can quickly analyze the change trend of total phosphorus concentration in wastewater, and solve the technical problem that traditional chemical testing methods cannot obtain continuous water quality data and carry out refined operation of the plant due to long detection time.

[0038] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
