[0020] The utility model provides Figure 1-3 The environmental protection and emission reduction treatment equipment for ammonia nitrogen wastewater shown in the figure comprises a treatment equipment body 1, which is supported by a supporting foot 4 at the lower end position. The treatment equipment body 1 transports ammonia nitrogen wastewater to an internal position through an inlet pipe 8 at the left end position. The inlet pipe 8 is provided with a filter screen A13 for filtering impurities at the internal position. The outer wall of the inlet pipe 8 is sleeved with a cover 7 at the lower position. A storage bottle 6 is installed at the inner side of the cover 7. The storage bottle 6 is installed with the cover 7 through a sealing gasket 14 at the upper end position. In order to increase the sealing performance during installation, a filter screen B16 is arranged at the internal position of the storage bottle 6. The storage bottle 6 is provided with a flow pipe 5 at the inner lower end position of the storage bottle 6 through a threaded structure 15 located at the inner wall position. The treatment equipment body 1 filters the ammonia nitrogen wastewater through the anaerobic tank 9, the anoxic tank 10, the aerobic tank 11 and the secondary sedimentation tank 12 at the internal position. The treatment equipment body 1 discharges the filtered wastewater through the water outlet 2 at the middle position on the left side, and the solid waste filtered out by the treatment equipment body 1 is discharged through the sewage outlet 3.

[0021] Wastewater containing ammonia nitrogen is introduced into the internal position of the treatment equipment body 1 through the water inlet pipe 8. The ammonia nitrogen wastewater first enters the anaerobic tank 9. Under anaerobic conditions, anaerobic bacteria convert organic matter into organic acids and ammonia nitrogen. In the anoxic tank 10, the anoxic bacteria further decompose the organic acids, and the ammonia nitrogen is oxidized to nitrate nitrogen by ammonia oxidizing bacteria. When entering the aerobic tank 11, the nitrate nitrogen is oxidized to nitrate by nitrifying bacteria, and the nitrate is reduced to nitrogen gas for discharge. Finally, the water body treated in the secondary sedimentation tank 12 is separated from the sludge, and the water body and the sludge are discharged through the water outlet 2 and the sewage outlet 3 respectively.

[0023] The filter net A13 filters the large impurities mixed in the ammonia nitrogen wastewater, and because the filter net A13 has a certain inclination, the filtered impurities fall into the internal position of the storage bottle 6. A filter net B16 is arranged at the internal position of the storage bottle 6. The ammonia nitrogen wastewater entering the storage bottle 6 sinks through the filter net B16 and can enter the internal position of the treatment equipment body 1 through the circulation pipe 5, thereby preventing impurities from entering the internal position and causing blockage.

[0024] like Figure 1 and Figure 3 As shown, the water inlet pipe 8 transports the impurities isolated by the filter net A13 to the internal position of the storage bottle 6. The storage bottle 6 is installed with the water inlet pipe 8 through the cover 7. The storage bottle 6 is installed with the circulation pipe 5 through the threaded structure 15. The circulation pipe 5 transports the ammonia nitrogen wastewater entering the storage bottle 6 to the internal position of the treatment equipment body 1.

[0025] When the storage bottle 6 is disassembled, the cover 7 can be rotated first to disassemble the cover 7 and the storage bottle 6, and the cover 7 can be moved to the upper position to remove the sealing gasket 14, and finally the storage bottle 6 can be rotated to separate it from the circulation pipe 5, and the disassembly is completed.
