specific Embodiment approach 1
[0021] Specific implementation mode one: combine figure 1 Describe this embodiment, a denitrification filter reactor using corncob as a biomass carrier in this embodiment includes a reactor main body, an inlet water tank 1, an inlet pipe 4, a plurality of outlet pipes 5 and a backwash inlet pipe 8;
[0022] The reactor main body includes a biomass carrier 6 and a supporting plate 7, and the biomass carrier 6 and the supporting plate 7 are arranged inside the reactor main body from top to bottom;
[0023] Below the supporting plate 7, a water inlet and a backwash water inlet are opened on the side wall of the reactor main body; above the supporting plate 7, a plurality of water outlets are opened from top to bottom on the side wall of the reactor main body; The water pipe 5 communicates with the reactor main body through the water outlet;
[0024] The water inlet tank 1 communicates with the reactor main body through the water inlet pipe 4 and the water inlet; the backwash wat...
specific Embodiment approach 2
[0033] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the main body of the reactor is closed. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: the support plate 7 is evenly provided with a plurality of holes with a diameter of 0.6 mm to 0.8 mm, and the perforations of the support plate 7 The rate is 10% to 15%. Other steps are the same as those in Embodiment 1 or 2.
