[0051] A microcontroller 26 is installed on the outer side wall of the filtered water tank 21 .

[0052] In addition, the present invention also provides a wastewater treatment method of a detachable wastewater treatment facility, comprising the following wastewater treatment steps:

[0053] S1, the wastewater is first pumped into the primary treatment mechanism 10, and passes through the mixing device in the chemical treatment chamber 12, where the flocculant, oxidant chemical reagent and the wastewater are fully mixed to form flocs, and the suspended particles and colloidal substances are preliminarily removed. The treated wastewater flows out from the lower outlet chamber 13 and enters the filtration outlet chamber 21 through the primary outlet pipe 14;

[0054] S2, after the wastewater enters the filter water tank 21 of the intermediate filter mechanism 20, it flows into the main filter 22 through the docking square pipe 23. The main filter 22 uses a high-precision fiber filter and multi-layer filter materials to remove suspended particles and fine particles in the wastewater as the use time increases;

[0055] S3, when the filtering efficiency of the main filter 22 decreases, the microcontroller 26 issues a command to start the moving replacement mechanism 40, and the slide 43 slides along the slide rail 41 under the drive of the stepper motor 45 to move the main filter 22 to the maintenance area, and at the same time replaces an auxiliary filter 27 to the position of the main filter 22;

[0056] S4. After the replacement is completed, the sealing mechanism 60 is started, and the bidirectional rod cylinder 61 pushes the side support plate 62 to move the middle sealing plate 63 and the side sealing plate 64 to the two ends of the newly installed main filter 22 and seal and fix them to the docking square tube 23;

[0057] S5, the second water pump 32 receives the wastewater after the intermediate filtration, and transports it to the disinfection chamber 31 through the drain pipe 33, and completes the disinfection treatment of microorganisms and other pollutants in the disinfection chamber 31. The disinfected water is pumped by the third water pump 34 through the water pipe 35 and transported to the discharge tank 36.

[0058] The main filter 22 is reinstalled into the intermediate filtering mechanism 20 and positioned to the working position by moving the replacement mechanism 40. At this time, the auxiliary filter 27 is restored to the standby state.

[0059] The working principle of the present invention is as follows: wastewater is first introduced from an external water source to the inlet of a primary treatment mechanism 10 through a pipeline or a pumping system. After entering the primary treatment mechanism 10, the wastewater is introduced into a chemical treatment chamber 12 supported by a chamber support 11. The chemical treatment chamber 12 is provided with a mixing device for mixing various chemical reagents, including flocculants, oxidants, reductants, acid-base regulators, etc. The specific types and dosages are adjusted according to the composition of the wastewater and the treatment objectives. In the chemical treatment chamber 12, the wastewater is fully mixed with the added chemical reagents. The role of the flocculant is particularly important at this stage. It can aggregate the suspended particles and colloidal substances in the wastewater into larger flocs, thereby facilitating subsequent separation and treatment. Other chemical reagents The agent may be used to oxidize or reduce certain soluble pollutants to convert them into a form that is easier to remove. The wastewater after chemical treatment gradually flows out from the bottom of the chemical treatment chamber 12 and enters the lower water outlet chamber 13. The lower water outlet chamber 13 is located below the chemical treatment chamber 12. Its function is to collect the wastewater that has undergone preliminary chemical treatment and guide it through the primary water outlet pipe 14 to ensure that the wastewater can flow smoothly into the lower water outlet chamber 13. The primary water outlet pipe 14 is connected to the bottom of the lower water outlet chamber 13 to guide the wastewater to flow to the next treatment unit, the filtration water outlet chamber 21. A primary pipe valve 15 is installed on the outer wall of the primary water outlet pipe 14. By adjusting the primary pipe valve 15, the flow rate of the wastewater entering the filtration water outlet chamber 21 can be accurately controlled;

[0060] After completing the primary treatment, the wastewater flows into the filter tank 21 in the intermediate filtering mechanism 20 through the primary outlet pipe 14. The filter tank 21 is the starting point for the wastewater to enter the intermediate filtering process. The main function of the filter tank 21 is to temporarily store the wastewater and guide it to flow into the main filter 22. The wastewater flows out of the filter tank 21 and enters the main filter 22 through the docking square pipe 23. The function of the docking square pipe 23 is to connect the filter tank 21 with the main filter 22 and ensure the sealing during the filtering process. The main filter 22 is the core component of the intermediate filtering stage and is composed of a high-precision fiber filter and a multi-layer filter. The filter medium of the filter material is composed of a filter medium. When the wastewater passes through the main filter 22, most of the suspended particles and larger fine particles will be retained on the filter medium, thereby achieving a preliminary purification effect. As the filtering time increases, the main filter 22 may gradually accumulate filtered impurities, causing the filtered water flow rate to slow down, so it needs to be cleaned or replaced regularly. The main filter 22 removes suspended particles and larger fine particles in the wastewater, so that the quality of the filtered water is significantly improved. During the operation of the main filter 22, the auxiliary filter 27 is in standby mode and does not participate in daily filtering work. The main function of the auxiliary filter 27 is to serve as a backup component. When the filtering effect of the main filter 22 decreases or fails, the auxiliary filter 27 can immediately replace the main filter to maintain the normal operation of the system;

[0061] When the filtering efficiency of the main filter 22 is reduced or clogged, the microcontroller 26 will issue a control command, the mobile replacement mechanism 40 is started, and the cooperation of the slide rail 41 and the tooth plate 42 causes the slide seat 43 to slide along the slide rail 41, first moving the main filter 22 from the working position to the position of an auxiliary filter 27, and then moving an auxiliary filter 27 to the position of the main filter 22 to ensure the continuous operation of the system. The replacement process is completed by the mobile replacement mechanism 40, which specifically includes:

[0062] Driven by the stepper motor 45, the gear 46 is driven to rotate by the stepper motor 45, and the movement of the slide 43 is precisely controlled by the meshing transmission of the gear 46 and the toothed plate 42. The bidirectional rodless cylinder 48 fixes the auxiliary filter 27 through the fixing plate 49. When the auxiliary filter 27 is moved to the position of the main filter 22 and ensures its tight connection with the docking square tube 23, after the replacement is completed, the replaced main filter 22 can be moved to the maintenance area for cleaning or replacement, and the auxiliary filter 27 begins to take on the filtering work of the main filter to ensure the continuity of wastewater treatment.

[0063] When the mobile replacement mechanism 40 completes the replacement of the filter (i.e., moves the auxiliary filter 27 to the position of the main filter 22 or installs the new main filter 22 in place), the sealing mechanism 60 is immediately started to ensure the seal between the newly installed filter and the docking square tube 23. The two-way rod cylinder 61 sends a command through the microcontroller 26 to start its two output rods to push the side support plates 62 to move toward the two ends of the newly installed main filter 22. The two middle sealing plates 63 are installed on the sides of the side support plates 62. As the side support plates 62 move, the middle sealing plates 63 gradually approach and fit into the docking gap between the newly installed main filter 22 and the docking square tube 23. The docking point between the middle sealing plate 63 and the filter is tightly sealed through the sealing groove 65 to ensure To ensure that the wastewater only flows in the filter without leakage, side sealing plates 64 are provided on both sides of the middle sealing plate 63. There are two side sealing plates 64, which cooperate with the middle sealing plate 63 to further ensure the sealing and fixity between the filter and the docking square tube 23. The second water pump 32 receives the wastewater after the intermediate filtration and transports it to the disinfection chamber 31 through the drain pipe 33. In the disinfection chamber 31, the wastewater is disinfected to remove microorganisms and other pollutants. Subsequently, the treated water is extracted by the third water pump 34 through the water diversion pipe 35 and transported to the discharge tank 36. The third water pump 34 ensures that the disinfected water can smoothly enter the discharge tank 36 for final discharge or storage, completing the last step of the entire wastewater treatment process.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
