[0002] Organic wastewater mainly comes from domestic sewage and industrial fields such as food processing, papermaking, pharmaceuticals, and chemicals. This type of wastewater has the characteristics of high organic matter concentration, complex composition, high chroma, and odor. It often contains suspended matter, grease, protein, and toxic and difficult-to-degrade organic matter. It has potential pollution and threats to the environment. It is necessary to effectively treat organic sewage and wastewater to avoid it from polluting the environment.

The organic wastewater treatment device according to claim 5, characterized in that: The upper ends of the inflatable cylinders (27) are respectively fixedly connected to and communicate with air guide tubes (40), the other ends of the air guide tubes (40) are respectively fixedly connected to second three-way tubes (37), the other two interfaces of the second three-way tubes (37) are respectively fixedly connected to an air inlet check valve (39) and an air outlet check valve (38), and the other ends of the two air outlet check valves (38) are commonly fixedly connected to a first three-way tube (36).

7. The organic wastewater treatment device according to claim 6, characterized in that: The lower ends of the longitudinally arranged check valves (33) are fixedly connected to a first connecting pipe (34), a plurality of first connecting pipes are fixedly connected and connected to a second connecting pipe (35), and the upper end interface of the first three-way pipe (36) is fixedly connected and connected to the second connecting pipe (35).

8. The organic wastewater treatment device according to claim 7, characterized in that: A plurality of connecting rings (46) are arranged in sequence from left to right inside the mixing chamber (3); the front and rear ends of the connecting rings (46) are respectively fixedly connected to support rods (45); the two ends of the support rods (45) are respectively rotatably connected to the inner wall of the mixing chamber (3); the filler rods (48) are respectively fixedly connected to the lower ends of the support rods (45); the surfaces of the connecting rings (46) are respectively fixedly connected to connecting gears (47) that mesh with each other; and under the meshing transmission of the connecting gears (47), the plurality of supporting rods (45) simultaneously reciprocate and swing.

9. The method for treating organic wastewater and sewage of an organic wastewater and sewage treatment device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, starting the first motor (8), and controlling the scraper (7) to rotate synchronously on the surface of the filter plate (6) through the first motor (8); S2, starting the second motor (41), driving the plurality of support rods (45) to swing back and forth through the second motor (41), and driving the filler rods (48) on the lower side to swing in a wave-like manner when the support rods (45) swing back and forth; at the same time, driving the aeration device to continuously aerate the interior of the mixing chamber (3) through the second motor (41), thereby increasing the oxygen content of the sewage; while the aeration device is working, driving the push plate (50) to continuously move back and forth up and down; S3, sewage enters through the first feed barrel and flows out through the second feed barrel. The ladder frame (49) filters a large amount of large particles of debris, and then the large particles of debris are removed by the push plate (50) moving up and down. The sewage entering the box is stirred into a vortex by the scraper (7) and is fully mixed with the filler rod (48) and oxygen. The aggregated particles filtered by the filter plate (6) are crushed by the rotation of the scraper (7) and are fully mixed with the filler rod (48) and oxygen under the mixing of the scraper (7), thereby achieving sewage denitrification and decomposition of organic matter in the sewage.
