One end of the inlet pipe 1 is connected to the deep-bed denitrification filter tank 3. An air pipe 15 at the bottom of the deep-bed denitrification filter tank 3 is connected to a blower 14. One end of a dosing pipe 19 is connected to a dosing tank 18. The blower 14 is located on the right side of the deep-bed denitrification filter tank 3, and the bottom of the blower 14 is connected to the air pipe 15. A wastewater tank 13 is located on the right side of the dosing tank 18, and a discharge pipe is connected to the left side of the wastewater tank 13. Water pipe 12, disinfection tank 10 is set on the left side of deep bed denitrification filter tank 3, water outlet pipe 2 is connected to the right side of disinfection tank 10, backwash water tank 11 is connected to the left side of disinfection tank 10 through a pipe, backwash water pipe 9 is connected to the bottom of backwash water tank 11, HDPE chassis 17 is installed at the bottom of the inner cavity of deep bed denitrification filter tank 3, air-water distribution system 6 is installed on the top of HDPE chassis 17, and control valves 20 are installed on backwash water pipe 9, drain pipe 12, air pipe 15 and chemical dosing pipe 19.

[0025] In some embodiments, a central spray pipe 32 is installed inside the deep bed denitrification filter tank 3. The left side of the water inlet pipe 1 is connected to the central spray pipe 32, and the right side of the water inlet pipe 1 is connected to the mixing tank 31. The mixing tank 31 is connected to the dosing pipe 19. By setting the central spray pipe 32, it is convenient to mix the treatment drugs and to treat the wastewater.

[0026] In other embodiments, Figure 1As shown, the top of the air-water distribution system 6 is covered with a pebble pad 5, and the top of the pebble pad 5 is covered with quartz sand filter media 4. By setting the pebble pad 5, it is easy to carry out layered filtration and to facilitate the treatment of sewage.

[0027] In some preferred embodiments, such as Figure 1 As shown, the outlet pipe 2 is equipped with an outlet lift pump 7. The right side of the outlet pipe 2 is connected to the deep bed denitrification filter tank 3. By setting the outlet lift pump 7, it is easy to transport sewage and easy to inject water into the disinfection tank 10.

[0028] In other embodiments, Figure 1 As shown, the backwash water pipe 9 is equipped with a backwash pump 8, and the backwash water pipe 9 is connected to the deep bed denitrification filter tank 3.

The water is filtered through the quartz sand filter media 4 and the pebble cushion layer 5, which can remove impurities and floating matter in the sewage. When the ammonia concentration in the sewage is high, the denitrifying bacteria in the quartz sand filter media 4 and the pebble cushion layer 5 convert the nitrate nitrogen in the water into nitrogen gas in an anaerobic environment, thereby achieving denitrification and nitrogen removal. The blower 14 injects air into the air-water distribution system 6, which disperses the air into the water in the deep bed denitrification filter tank 3. The sewage is pumped into the disinfection tank 10 for disinfection by the outlet water lift pump 7 and then discharged. The disinfected water can flow into the backwash water tank 11. The backwash water tank 11 is pumped back to the deep bed denitrification filter tank 3 by the backwash pump 8 for backwashing. Through the above operations, air and water are distributed.
