5. The sewage denitrification processing apparatus for domestic sewage according to claim 1, wherein the length dimension of the bottom plate (34) is larger than the diameter dimension of the restriction plate (24).
6. A sewage denitrification treatment device for domestic sewage and a use method of the sewage denitrification treatment device are characterized by comprising the following steps:
the method comprises the following steps: the domestic sewage which needs to be denitrified is discharged into the pipe body (8) from the water inlet hopper (1), the ammonia nitrogen remover is thrown into the metering box (2), the motor (4) is checked, the motor (4) is turned on to enable the motor (4) to rotate, the motor (4) rotates to drive the transmission rod (6) to rotate, the transmission rod (6) rotates to drive the stirring blade (7) to rotate, the stirring blade (7) rotates to stir the sewage, the transmission rod (6) rotates to drive the rotating plate (32) to rotate, the rotating plate (32) rotates to drive the ejector rod (3) positioned above the rotating plate (32) to be attached to the surface of the rotating plate (32) to realize up-down movement, the surface of the rotating plate (32) is arranged to be of a multi-section arc structure, the end part of the ejector rod (3) is arranged to be of an arc structure, so that the ejector rod (3) moves smoothly on the rotating plate (32), and the top part of the ejector rod (3), the side wall of the sealing plate (18) is provided with a sliding plate (21), the sliding plate (21) can slide in the sliding groove (19), so that when the ejector rod (3) moves upwards, the ejector rod (3) drives the sealing plate (18) to move upwards, the lower liquid opening (20) is opened, the clean ammonia nitrogen remover in the metering tank (2) can enter the pipe body (8) and the domestic sewage, the sewage and the clean ammonia nitrogen remover are uniformly stirred by a stirring mechanism, and nitrogen in the sewage is removed;
step two: the transmission rod (6) rotates to drive the first bevel gear (5) to rotate, the rotation of the first bevel gear (5) drives the second bevel gear (10) to rotate, so that the second bevel gear (10) drives the threaded rod (23) to rotate, the threaded rod (23) rotates to drive the threaded sleeve (22) to move upwards, the threaded sleeve (22) moves upwards and then an L-shaped rod (33) fixed on the threaded sleeve (22) can abut against the baffle (14), the baffle (14) is turned over, the rotary pin (30) rotates inside the rotary groove (31) when the baffle (14) is turned over, the driven rod (11) can be attached to the inside of the rod groove (28) when the baffle (14) is turned over, and at the moment, water flows to the lower part of the pipeline (8) from two sides of the baffle (14) and is filtered from the filter screen (15); finally, the filtered water is discharged from a water outlet (16); at the moment, the motor (4) is turned over to enable the threaded rod (23) to rotate, the L-shaped rod (33) descends, and the baffle (14) resets;
step three, can make filter screen (15) top appear impurity after long-time use, thereby to filter screen (15) jam, when filter screen (15) jam is serious, need take out filter screen (15), rotate bottom plate (34) to the below earlier, thereby make things convenient for taking out of filter screen (15) when taking out filter screen (15), need upwards promote limiting plate (24), make cardboard (25) break away from annular fagging (26), incline filter screen (15), take out cardboard (25) one end earlier, thereby make limiting plate (24) taken out, filter screen (15) are taken out, carry out the edulcoration to filter screen (15), after the washing, press filter screen (15) back, thereby make filter screen (15) continue to filter.
