[0023] Referring to Figure 2 Specifically, the detection assembly 60 comprises a first telescopic assembly 61, a second telescopic assembly 62 and a detection sensor 63, the first telescopic assembly 61 is arranged on the side wall of the tank body 10 and can be telescoped in a first direction (i.e. a horizontal direction), the second telescopic assembly 62 is connected with the first telescopic assembly 61 and can be telescoped in a second direction (i.e. a vertical direction), and the detection sensor 63 is arranged at the tail end of the second telescopic assembly 62 and is used for monitoring the nitrogen and phosphorus content of water in real time. In use, the first telescopic assembly 61 is elongated to the side away from the side wall of the tank body 10, so that the second telescopic assembly 62 and the detection sensor 63 are sent to the top of the sewage pool, then the depth of the detection sensor 63 is adjusted by controlling the elongation of the second telescopic assembly 62, so that the detection sensor 63 can be completely immersed in the sewage, and once the detection sensor 63 is located in the water, it can accurately monitor the nitrogen and phosphorus content in the water. Subsequently, the data detected by the detection sensor 63 is transmitted to the control assembly 70 connected with the detection sensor 63.

[0024] Referring to Figure 2, preferably, the first telescopic assembly 61 comprises a first telescopic arm 611 and at least one first driving member 612. The first telescopic arm 611 comprises at least two first arm portions telescopically connected, one end (i.e. the fixed end) of the first telescopic arm 611 is connected with the tank body 10 and the other end (i.e. the outer end) is connected with the second telescopic assembly 62, in other words, one first arm portion of one end of the first telescopic arm 611 is formed as the fixed end and connected with the side wall of the tank body 10, and one first arm portion of the other end of the first telescopic arm 611 is formed as the outer end and connected with the second telescopic assembly 62, so that the second telescopic assembly 62 moves horizontally when the first arm portions relatively move. Each first driving member 612 can be connected with two adjacent first arm portions to drive the two adjacent first arm portions to telescopically move, the telescopically moving of the two adjacent first arm portions is stable and not easy to be skewed, which is beneficial to improve the stability of the horizontal movement of the first telescopic assembly 61, and the structure is simple and easy to control.

[0025] Referring to Figure 2 Alternatively, the first arm portion can be a square section sleeve, taking the first telescopic arm 611 comprising two first arm portions as an example, a first square section sleeve is fixed to the side wall of the tank body 10, and a second square section sleeve is inserted into the first square section sleeve, under the power of the first driving member 612, the second square section sleeve extends outward under the guidance of the first square section sleeve, so that the first telescopic arm 611 is elongated, and during the elongation process, the first square section sleeve and the second square section sleeve do not rotate relative to each other, which is beneficial to improve the connection stability with the first driving member 612 and the structural stability of the first telescopic arm 611, and facilitates the installation and fixation of the first driving member 612.

The second telescopic arm 621 comprises at least two second arm portions telescopically connected, one end of the second telescopic arm 621 is connected with the first telescopic assembly 61, and the other end is provided with the detection sensor 63. Each second driving member 622 is connected with two adjacent second arm portions to drive the two adjacent second arm portions to telescopically move, and the second driving member 622 can limit the two adjacent second arm portions, preventing the two adjacent second arm portions from elongating too fast or even separating and falling off in the vertical direction under the action of gravity, which is beneficial to improve the stability and safety of the vertical movement of the second telescopic assembly 62. The second arm portion can be a square section sleeve to prevent the two adjacent second arm portions from rotating relative to each other, and facilitate the connection of the second arm portion with the second driving member 622.

[0027] In the present application, the detection sensor 63 includes a nitrogen content sensor and a phosphorus content sensor. The nitrogen content sensor is responsible for detecting the nitrogen content in sewage, including ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, etc. It can quickly and accurately reflect the pollution degree of nitrogen in sewage, providing important reference data for the control component 70. The phosphorus content sensor is used to detect the phosphorus content in sewage, mainly in the form of phosphate. Phosphorus is one of the main elements that cause water eutrophication, so accurate detection of phosphorus content is crucial to control the eutrophication of sewage. In the present application, the nitrogen content sensor and the phosphorus content sensor are installed at the end of the detection assembly 60, which is composed of the first telescopic assembly 61 and the second telescopic assembly 62. These telescopic assemblies can adjust the position and depth of the sensors, ensuring that the sensors can reach different positions in the sewage and obtain more comprehensive and accurate detection data. The data collected by the detection assembly 60 is transmitted to the control component 70 in real time, and the PLC controller in the control component 70 can intelligently adjust the proportion of the nitrogen removal agent tank 20 and the chemical flocculant tank 30 according to these data. This intelligent control method can ensure the precise use of the agent, avoid excessive or insufficient dosage, and improve the utilization efficiency of the agent.

[0028] Referring to Figure 1 Preferably, the stirring assembly 50 includes a stirring motor 51, a stirring shaft 52, and a plurality of stirring blades 53.

Through the driving of the stirring motor 51, the stirring shaft 52 drives the stirring blades 53 to rotate in the tank body 10, so that the agent is fully mixed in the tank body 10. This mixing method can ensure the uniformity of the agent and improve the efficiency of nitrogen and phosphorus removal.

[0029] Referring to Figure 1Preferably, the control assembly 70 comprises a control unit 71, a PLC controller arranged in the control unit 71, and a touch display screen 72 connected to the PLC controller. The control unit 71 is the basis of the entire control assembly 70, which provides a stable and reliable working environment for the core components such as the PLC controller and the touch display screen 72. The control unit 71 usually contains necessary power supply, heat dissipation and protection devices to ensure the stable operation of the control assembly 70 in various environments. The PLC (Programmable Logic Controller) controller is the core component of the control assembly 70. It receives real-time data from the detection assembly 60, such as the nitrogen and phosphorus content of the sewage, and controls the opening and closing of the electromagnetic valve 40 according to the preset program logic and algorithm, thereby adjusting the proportion of the nitrogen removal agent tank 20 and the chemical flocculant tank 30. The touch display screen 72 is the window for users to interact with the device, which displays the running status of the device, the nitrogen and phosphorus content of the sewage, the amount of agent, and other information in real time, enabling users to intuitively understand the operation of the device. In addition, users can also set parameters, view historical data, troubleshoot and other operations through the touch display screen 72, improving the ease of use and maintenance efficiency of the device.

[0030] It should be noted that nitrogen in sewage mainly exists in the form of ammonia nitrogen, nitrite nitrogen and nitrate nitrogen in wastewater. The denitrification process mainly includes two biological processes: nitrification and denitrification. Denitrification: nitrate is reduced to nitrogen gas and escapes from the system in this step. This process is carried out under anaerobic conditions by denitrifying bacteria such as Pseudomonas and Bacillus. The artificial carbon source for denitrification includes pure chemical agents such as methanol, ethanol, denatured ethanol, acetic acid and sodium acetate, or industrial waste sugar, molasses and waste acetic acid solution. Phosphorus usually exists in the form of phosphate in wastewater. The purpose of phosphorus removal is to convert this dissolved inorganic phosphate into a solid state, so that it can be physically removed from the system. The main method of phosphorus removal is chemical phosphorus removal, that is, by adding chemical flocculants (such as aluminum chloride, iron chloride or iron hydroxide) to react with phosphate to form a precipitate.

[0031] In order to effectively remove nitrogen and phosphorus, in this application, the denitrification agent tank 20 is loaded with pure chemical agents such as methanol, ethanol, denatured ethanol, acetic acid or sodium acetate. The chemical flocculant tank 30 is loaded with chemical agents such as aluminum chloride, iron chloride or iron hydroxide.

[0032] Preferably, an electromagnetic valve 40 is arranged at the agent outlet 11. The application of the electromagnetic valve 40 at the agent outlet 11 mainly plays the role of accurately controlling the flow of the agent. Through the instruction of the PLC controller, the electromagnetic valve 40 can accurately open or close, thereby controlling the amount of agent. It should be noted that the user inputs the sewage content of the sewage tank through the touch display screen 72, thereby controlling the amount of agent.

[0033] In use, ensure that the device and each component is in normal working condition, check the power supply, electromagnetic valve 40, stirring assembly 50 and the like, and ensure that everything is ready. Then place the device next to the sewage pool or in a suitable position, ensure that the device is stable and convenient to operate, connect the device to the power supply and turn on the device. Set the total amount of sewage in the sewage pool through the touch display screen 72. Then start the detection assembly 60, the first telescopic assembly 61 extends the second telescopic assembly 62 and the detection sensor 63 above the sewage pool, and then adjusts the depth of the detection sensor 63 by controlling the extension of the second telescopic assembly 62, so that it is completely immersed in the sewage, and then the detection sensor 63 detects the nitrogen content and the phosphorus content of the sewage; according to the detected sewage content information, the control assembly 70 intelligently adjusts the proportion of the nitrogen removal agent tank 20 and the chemical flocculant tank 30, and then adjusts the appropriate nitrogen and phosphorus reaction drug proportion; then the stirring motor 51 drives the stirring shaft 52 to rotate, so that the reagent is fully mixed in the tank body 10, and the uniformity of the reagent is ensured. Finally, the control assembly 70 controls the amount of reagent discharged from the electromagnetic valve 40, so as to ensure the accurate use of the reagent.

[0034] The utility model provides a kind of sewage nitrogen and phosphorus removal reagent adding equipment, including a tank body 10, a nitrogen removal agent tank 20, a chemical flocculant tank 30, multiple electromagnetic valves 40, a stirring assembly 50, a detection assembly 60 and a control assembly 70. The nitrogen and phosphorus content of sewage is collected by detection assembly 60 extending into sewage, and the device can accurately understand the pollution degree of sewage, then, the control assembly 70 receives the detection information of detection assembly 60, controls the opening and closing of electromagnetic valve 40, intelligently adjusts the proportion of nitrogen removal agent tank 20 and chemical flocculant tank 30, ensures the accurate use of reagent, avoids the situation that drug is excessively put in or insufficiently put in, to improve the utilization efficiency of reagent. At the same time, the stirring assembly 50 is equipped to ensure that the reagent is fully mixed and discharged into sewage, so that sewage is uniformly reacted. Therefore, the sewage nitrogen and phosphorus removal reagent adding equipment realizes accurate nitrogen and phosphorus removal effect, effectively prevents the influence of excessive purification reagent on purification reaction, ensures the efficient sewage treatment, reduces treatment cost and saves resources.
