When the multiple annular cylinders are installed, the first plug-in plate is plugged into the first slot, and the second slot is plugged into the second plug-in plate to ensure the sealing degree of the device;

[0019] High-concentration ammonia nitrogen wastewater is pumped into the system and mixed with the refluxed short-range nitrification liquid (containing a large amount of nitrite). The mixed liquid enters the anaerobic ammonia oxidation reaction section at the bottom of the vertical reaction tank. Under anaerobic conditions, ammonia nitrogen reacts with nitrite to generate nitrogen gas, and the nitrogen element is removed. The wastewater continues to rise and enters the denitrification reaction section, and mixes with the refluxed mud water mixture (containing nitrite and nitrate).

[0022] Start the servo motor, the output shaft of the servo motor drives the bidirectional screw to rotate, the bidirectional screw drives the two threaded blocks to move away from each other, the threaded blocks drive the two support rods to move away from each other, and then the support rods are separated from the fixing ring, and then the electric push rod is started to move the support rod upward, and the servo motor is started to move the two support rods closer to each other and move to the bottom of the upper fixing ring, and this reciprocating process is completed;

[0023] After the multiple annular cylinders are disassembled, the inner cylinder inside the annular cylinder can be rotated, the inner cylinder drives the mounting ring to rotate, the mounting ring drives the rectangular block to rotate, and when the rectangular block rotates inside the annular groove to the bottom of the notch, the inner cylinder is moved vertically upward to take out the inner cylinder;

[0024] After the inner cylinder is taken out, since the inner wall of the second annular block no longer conflicts with the positioning rod, the positioning rod and the sliding block move laterally under the tension of the second tension spring. After the positioning rod moves laterally, the positioning rod moves out from the inside of the positioning hole, and the braking state of the vertical rod can be released. At this time, the second filter plate can drive the two vertical rods to move vertically upward. After the second filter plate is disassembled, the internal filler can be replaced, which is convenient to use.

[0025] Beneficial effects: Efficient treatment: Through the organic combination of biological treatment technologies such as anaerobic ammonia oxidation, denitrification, short-range nitrification and aerobic nitrification, efficient treatment of high-concentration ammonia nitrogen wastewater is achieved. Each reaction stage is carried out under suitable conditions, which improves the removal efficiency of nitrogen elements.

[0026] Good sealing: The sealing degree of the device is ensured by the clamping connection between the first plug plate and the first slot, and the second slot and the second plug plate, thereby avoiding the problems of wastewater leakage and secondary pollution.

[0027] Convenient packing replacement: This device is designed with a unique packing replacement mechanism. By turning the rotating block, starting the electric push rod and servo motor, the annular cylinder and the inner cylinder can be easily disassembled to replace the internal packing. This design not only improves the convenience of maintenance, but also ensures the continuous and efficient use of the packing.

[0028] Compact structure: The internal structure of the device is reasonably designed, and the components are closely matched, making the overall structure compact and occupying a small area, suitable for use in limited space.

[0029] Easy operation: The working method of this device is simple and clear. The operator only needs to follow the steps to complete the wastewater treatment and filler replacement, which reduces the operation difficulty and labor cost. BRIEF DESCRIPTION OF THE DRAWINGS
