[0031] Another technical problem that the present invention aims to solve is a method for using a wastewater treatment device based on high-altitude tunnel construction in a water source protection area, Step S1 involves performing a liquid injection and mixing operation on wastewater, which includes turning on the switch of the first drive motor 33 so that the output terminal of the first drive motor 33 is output, moving and rotating the screw stirring blade 35 and the inclined stirring blade 37, injecting a small amount of chlorine dioxide liquid into the liquid injection mixing container 31, performing a liquid injection and mixing operation on the inhaled wastewater, crushing any solid sludge clumps during the mixing process with the screw stirring blade 35, and further increasing the mixing efficiency by the inclined arrangement of the inclined stirring blade 37, Step S2 involves performing wastewater treatment on the liquid drawn into the liquid input mixing unit 3, starting with the first suction pump 211, injecting the liquid drawn in from the liquid input mixing unit 3 into the anaerobic tank 21 to treat the wastewater anaerobically, then starting the second suction pump 221 to draw the anaerobic treated wastewater from the anaerobic tank 21 into the aerobic tank 22 to perform aerobic treatment of the wastewater, and since the aerobic tank 22 and the sludge tank 23 are interconnected, the aerobic treated wastewater in the aerobic tank 22 is put into the sludge tank 23 for sludge sedimentation, and since the filtration tank 24 and the sludge tank 23 are interconnected, the wastewater in the sludge tank 23 is partially returned to the filtration tank 24, and then starting the third suction pump 241 to partially draw the aerobic treated wastewater in the aerobic tank 22 into the filtration tank 24 for reaction. Step S3 involves performing a step-by-step filtration operation on the wastewater in the filtration tank 24, which is carried out by performing a step-by-step filtration operation on the wastewater flowing through the filtration net cover plate 242 and multiple sets of filtration nets 243 provided in the filtration tank 24, Step S4 involves injecting chlorine dioxide liquid into the filter tank 24, which is done by opening the switch of the metering pump 63 so that the output terminal of the metering pump 63 is output, injecting the chlorine dioxide solution in the kettle 62 into the filter tank 24, and performing a disinfection operation on the inside of the filter tank 24. Step S5 involves starting the third drive motor 72 so that its output terminal outputs, moving the connecting plate 76 in the left-right direction, simultaneously opening the downward pushing cylinder 77, which outputs a signal from its output terminal, moving the concentration detector 79 downward, detecting the chlorine dioxide concentration in the liquid in the filtration tank 24, and if a low concentration of chlorine dioxide in the filtration tank 24 is detected, continuing to inject chlorine dioxide liquid into the filtration tank 24 through the chlorine dioxide supply member 6, thereby performing the chlorine dioxide concentration measurement operation in the filtration tank 24. Step S6 involves starting the sludge recirculation pump 42 so that its output terminal is output, recirculating the sludge in the sludge tank 23 into the anaerobic tank 21, and continuing the anaerobic reaction of the recirculated sludge in the anaerobic tank 21. Step S7 involves starting the second drive motor 53 so that its output terminal is output, moving and rotating multiple sets of roller brushes 56 to wipe the elastic plate located inside the filtration tank 24, thereby intermittently wiping the elastic plate through the multiple sets of roller brushes 56 to remove sludge, and simultaneously driving the disc-shaped gear 594 to reciprocate the vibrating rod 59, causing the elastic plate located inside the filtration tank 24 to vibrate back and forth. As a result, the sludge on the elastic plate inside the filtration tank 24 vibrates and falls off, preventing the sludge from clumping and remaining on the elastic plate. The vibrated and wiped sludge all remains at the bottom of the filtration tank 24 and can be easily collected. Step S8 involves performing aeration in the filtration tank 24, which involves starting the fan set 81 so that the output terminal of the fan set 81 outputs, performing aeration in the filtration tank 24, and installing the aeration duct 84 in an I-shape so that a large area of ​​aeration can be performed in the filtration tank 24. By installing the aeration head 85 which has a wide lower part and a narrow upper part, the gas discharge efficiency can be further increased, while sufficient stirring and mixing action can be generated to promote the circulation and flow of water, and a constant movement speed of the mixed liquid can be maintained, keeping the remaining sludge in a suspended state in the mixed liquid at all times, thereby increasing the disinfection efficiency of chlorine dioxide during the reaction. Step S9 includes starting the fifth suction pump 93 so that its output terminal is turned on, and performing a collection operation on the liquid in the filtration tank 93, which involves sucking the liquid in the filtration tank 24 into the collection container 91.

[0032] As described above, after opening the first suction pump 211 through the provided wastewater treatment unit 2, the liquid sucked in from the liquid input mixing unit 3 is injected into the anaerobic tank 21 to perform anaerobic treatment on the wastewater. Then, the second suction pump 221 is started, and the anaerobic treated wastewater is sucked from the anaerobic tank 221 into the aerobic tank 22 to perform aerobic treatment on the wastewater. Since the aerobic tank 22 and the sludge tank 23 are interconnected, the aerobic treated wastewater in the aerobic tank 22 is put into the sludge tank 23 for sludge settling treatment. Also, since the filtration tank 24 and the sludge tank 23 are interconnected, the contents of the sludge tank 23 The third suction pump 241 is activated so that wastewater can be partially returned to the filtration tank 24, and the aerobic treated wastewater in the aerobic tank 22 is partially drawn into the filtration tank 24 by the third suction pump 241 for reaction, and the wastewater is filtered in stages in the filtration tank 24, and the sludge return unit 4 is provided so that the sludge can be returned from the sludge tank 23 to the anaerobic tank 21 for reaction, and the sludge vibration unit 5 is provided so that the output terminal of the second drive motor is output, and multiple sets of rollers are used to wipe the elastic plate located in the filtration tank 24 The bristles 56 are moved and rotated, allowing for intermittent wiping of the elastic plate through multiple sets of roller brushes 56 to remove sludge. The disc-shaped gear 594 is driven to reciprocate the vibrating rod 59, causing the elastic plate located inside the filtration tank 24 to vibrate back and forth. The sludge on the elastic plate inside the filtration tank 24 vibrates and falls off, preventing it from clumping together and remaining on the elastic plate. All the vibrated and wiped sludge remains at the bottom of the filtration tank 24 and can be easily collected. The provided chlorine dioxide supply member 6 allows for disinfection by injecting chlorine dioxide liquid into the filtration tank 24. To facilitate use, a chlorine dioxide concentration detection member 7 is provided to detect the concentration of the chlorine dioxide liquid in the filtration tank 2. If it detects that the chlorine dioxide liquid concentration is too low, the chlorine dioxide concentration detection member 6 then proceeds to inject more chlorine dioxide liquid into the filtration tank. The fan set 81 is activated via the provided aeration unit 8 so that its output terminal is output, and this is used to aerate the inside of the filtration tank 24. By installing the aeration duct 85 in an I-shape, a large area of ​​aeration can be performed inside the filtration tank, and the wide lower section...By installing an aeration head with a narrow upper section, the gas discharge efficiency can be further increased, while sufficient stirring and mixing action can be generated, promoting the circulation and flow of water. Furthermore, a constant movement speed of the mixed liquid can be maintained, keeping the remaining sludge suspended in the mixed liquid at all times, thereby improving the disinfection efficiency of chlorine dioxide during the reaction.
