Description

Technical Field

[0001] The utility model mainly relates to the field of sewage treatment, and in particular to a contact oxidation sewage treatment device. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly becoming part of the daily lives of ordinary people.

[0003] Contact oxidation processes are characterized by high efficiency and energy conservation, a small footprint, resistance to shock loads, and easy operation and management. Therefore, they are widely used in the treatment of industrial wastewater, aquaculture wastewater, and domestic sewage. The basic principle of this process is to place packing within a reactor. After oxygenation, wastewater comes into contact with the packing. The wastewater is purified through the dual action of the biofilm growing on the packing and the activated sludge within the packing's interstices. Most microorganisms grow fixedly on the packing surface as a biofilm, while a smaller portion grows suspended in the water as activated sludge.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] However, when a gap appears between the filler and the shell, the sewage is discharged directly through the gap, preventing the sewage from coming into contact with the filler. As a result, the impurities inside the sewage cannot be absorbed by the biofilm inside the filler, thereby reducing the treatment effect of the contact oxidation method on sewage.

[0006] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

A packing structure 5 is provided between the mounting groove 4 and the fitting strip 3, and a vibration structure 7 is provided inside the packing structure 5;

[0032] The packing structure 5 includes a bottom fixing bar 501 and a top fixing bar 502. The bottom fixing bar 501 is arranged at the bottom of the inner wall of the sewage treatment shell 1, the bottom fixing bar 501 is arranged inside the fitting bar 3, and the top fixing bar 502 is arranged on the inner wall of the mounting groove 4. The top of the top fixing bar 502 is rotatably connected to an adjusting bolt 503, and the adjusting bolt 503 is threadedly connected to the mounting groove 4. A packing filter membrane 504 is arranged between the top fixing bar 502 and the bottom fixing bar 501.

[0033] Furthermore, a dewatering groove 6 is provided at the bottom of the sewage treatment shell 1, and a threaded feeding rod 8 is rotatably connected inside the dewatering groove 6. When the motor is started, the motor drives the threaded feeding rod 8 to rotate, and the threaded feeding rod 8 discharges larger impurities in the sewage, and a valve is provided at one end of the dewatering groove 6 for sealing the sewage treatment shell 1.

[0034] Furthermore, the number of the packing structures 5 is set to be multiple, and the multiple packing structures 5 are evenly spaced inside the sewage treatment shell 1. The multiple packing structures 5 can perform multi-layer filtration on the sewage, and the packing filter membrane 504 is double-layered. Filler is provided inside the packing filter membrane 504 for subsequent biofilm growth. Water enters the interior of the sewage treatment shell 1 through the water inlet and outlet 2 on one side of the sewage treatment shell 1 and is discharged through the water inlet and outlet 2 on the other side of the sewage treatment shell 1. At the same time, rotating the adjusting bolt 503 can adjust the stretching degree of the packing filter membrane 504.

[0035] Furthermore, the vibration structure 7 includes a transmission shaft 701 and a rotating tube 704, the transmission shaft 701 is rotatably connected to the inner wall of the sewage treatment shell 1, the transmission shaft 701 is arranged inside the filler filter membrane 504, and cam bodies 702 are provided at both ends of the transmission shaft 701. The number of the transmission shafts 701 is set to multiple, and the multiple transmission shafts 701 are connected by a belt transmission structure 703. The outer walls of the rotating tube 704 and the transmission shaft 701 are provided with synchronous wheels 705, the number of the rotating tubes 704 is set to two, and the two rotating tubes 704 are distributed at the top and bottom of the transmission shaft 701.

The air inlets 707 are evenly spaced on both sides of the outer wall of the synchronous belt 706. When it is necessary to clean the impurities on the surface of the stuffing filter membrane 504, the motor is started, and the motor rotates through the belt transmission structure 703. The belt transmission structure 703 drives the transmission shaft 701 to rotate, and the transmission shaft 701 drives the cam body 702 to rotate.

At the same time, the air pump ejects air through the air inlet 707 on the outer wall of the rotating tube 704, so that the air enters the sewage. The motor is started, and the motor rotates through the belt transmission structure 703. The belt transmission structure 703 drives the transmission shaft 701 to rotate, and the transmission shaft 701 drives the cam body 702 to rotate. The contact between the cam body 702 and the stuffing filter membrane 504 can cause the stuffing filter membrane 504 to vibrate, and the vibration shakes off impurities on the surface of the stuffing filter membrane 504. At the same time, the air pump can feed air into the interior of the rotating tube 704, and during the rotation of the transmission shaft 701, the rotating tube 704 is driven to rotate synchronously through the synchronous wheel 705 and the synchronous belt 706, so that the air inlet 707 feeds air into the sewage, so that the sewage is filled with air.

[0037] After the sewage is discharged, the valve at one end of the outlet trough (6) is opened, and the vibration structure (7) continues to vibrate the filler filter membrane (504), so that larger impurities on the surface of the filler filter membrane (504) fall off and enter the interior of the outlet trough (6). The motor is started, and the motor drives the threaded feed rod (8) to rotate, and the threaded feed rod (8) discharges the impurities inside the outlet trough (6).
