[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0025] Example 1: An energy-saving and efficient sewage treatment equipment of an oxygen-containing FFBR, such as Figure 1-7As shown, it includes a shell 1 for equipment support, which is made of a material with high hardness (customized according to the size, shape and weight of the equipment or structure); a partition 2, the shell 1 is sealed and fixed with four partitions 2, the surface of the partition is smooth and made of a hard material, and the partition 2 divides the shell 1 into five chambers, namely: an anaerobic tank 21, an anaerobic tank 22, an aerobic tank 24, a filter tank 25 and a placement tank 26. The five cavities realize different functions in the process of treating wastewater; an overflow port 23, the anaerobic tank 21, the anaerobic tank 22, the aerobic tank 24 and the filter tank 25 are connected to the anaerobic tank 21. The upper part of the partition 2 between the filter tanks 25 is provided with an overflow port 23. When the liquid level is higher than the overflow port 23, the sewage flows into the next process through the overflow port 23; the sewage pipe 4 is installed on the front side of the lower part of the anaerobic tank 21, the facultative anoxic tank 22, the aerobic tank 24 and the filter tank 25. The sewage pipe 4 is in a normally closed state and is opened when discharging sewage and cleaning. The sewage pipe 4 passes through the shell 1 and is connected to the inside of the shell 1; the water inlet pipe 5 is connected to the upper left side of the shell 1 and is connected to the water inlet pipe 5. The external wastewater flows into the shell 1 through the water inlet pipe 5; the fan 6 is fixedly installed in front of the placement slot 26 for The external air is drawn into the device; the core filter assembly 8 is provided in the aerobic pool 24; the filter sheet 81, the core filter assembly 8 is evenly installed with multiple layers of filter sheets 81, the flow direction of the sewage is from the left side of the core filter assembly 8, and flows to the right through the layers of filter sheets 81, the filter sheets 81 are provided with granular materials for absorbing dirt, and the sewage will be absorbed by the filter sheets when it contacts the filter sheets 81; the drain outlet is provided at the rear side of the filter pool 25; the backwash motor 9 is installed at the front side of the placement tank 26, and is used to draw liquid from the external backwash equipment. body; a water inlet pipe 91 connected to the backwash motor 9, the water inlet pipe 91 passes through the rear part of the shell 1; a backwash water pipe 92, which penetrates into the filter tank 25 from the left partition 2 of the placement tank 26, and the backwash water pipe 92 passes through all the filter sheets 81 on the core filter assembly 8. Clean water is drawn in through the water inlet pipe 91 on the backwash motor 9 and flows out through the backwash water pipe 92 to flush and clean the working filter sheets 81; a water pump 7, a water pump 7 is installed on the front side of the placement tank 7, and the water pump 7 draws out the liquid in the filter tank 25 through the water pump pipe 72 and discharges it through the water outlet pipe 71.

[0026] Initially, the water inlet pipe 5 is connected to the external sewage conveying pipe, and the sewage flows into the anaerobic tank 21 through the water inlet pipe 5. Anaerobic bacteria are placed in the anaerobic tank 21 to stabilize the organic matter in the sewage, effectively degrade the difficult-to-degrade organic matter in the sewage, and reduce the volume of sludge in the sewage. The sewage is continuously transported from the outside to the anaerobic tank, and the sewage level in the anaerobic tank 21 will gradually rise. After a period of time, the sewage level covers the overflow port 23 on the right side partition 2 of the anaerobic tank 21, and the sewage in the anaerobic tank 21 flows into the anoxic tank 22 through the overflow port 23. In the anoxic tank 22, the odor generated by the reaction of anaerobic bacteria and sewage in the sewage and the odor in the sewage are treated to a certain extent by adding a carbon source. At the same time, when the sewage continues to flow into the anoxic tank 2 2, after a certain period of time, the sewage in the aerobic tank 22 will flow into the aerobic tank 24 through the overflow port 23 on the right side of the partition 2. In the aerobic tank 24, the organic matter in the sewage is converted into inorganic matter to reduce the organic load. A plurality of holes for inputting gas are opened on the air pipe 2 62 at the lower part of the aerobic tank 24. Synchronously, when the sewage enters the aerobic tank 24, the fan 6 is controlled to start and the fan 6 is operated to transport the outside air into the aerobic tank 24 through the air pipe 2 62. By transporting the outside gas into the sewage, the reaction of organic matter in the sewage is accelerated and the activity of sludge in the sewage is increased, so as to improve the efficiency of the subsequent sewage treatment process. After the sewage completes the biochemical treatment in the aerobic tank 24, it flows into the filter tank 25 through the overflow port 23 on the right. When the sewage liquid level is immersed in the filter tank 25, the sewage will be discharged to the filter tank 25. When the core filter assembly 8 in the filter pool 25 is used, the filter sheet 81 on the core filter assembly 8 is provided with a solid material for adsorbing particulate dirt. When the sewage contacts the filter sheet 81, the filter sheet causes the sludge and other solid substances in the sewage to be adsorbed on the filter sheet 81 and to be peeled off in layers through the surface of the filter sheet 81. It should be noted that the filter sheet 81 is formed by arranging and combining a plurality of linear fiber filaments in a high-density mesh shape, and welding and fixing the arranged wire bundles through a flexible supporting material. Through the core filter assembly 8, the macromolecules in the sewage are intercepted and the sewage is separated into solid and liquid. At the same time, the single filter sheet 81 is relatively thin, which can greatly increase the density of the filter sheet 81 filled in the core filter assembly 8, and the water with less impurities can penetrate through the filter sheet. , while granular solid dirt will be adsorbed and blocked, reducing space occupancy while improving sewage treatment effects and effectively reducing energy consumption. At the same time, it should be noted that a plurality of holes for outflowing liquid are opened on the backwash water pipe 92 in the filter pool 25, and the backwash water pipe 92 passes through two core filter components 8 and all filter sheets 81. When the core filter component 8 treats sewage, the backwash motor 9 is started, and clean water from the outside is connected through the water inlet pipe 91 and flushed out through the backwash water pipe 92. The clean water can directly penetrate the filter sheet 81 and flush the filter sheet 81 on the core filter component 8. In addition, during the backwashing process, the water flow impacts the flexible filter sheet 81, which will cause the filter sheet 81 to shake, and the impurities on the filter sheet 81 can be shaken more effectively.At this time, the stains on the filter plate 81 will float along the surface of the filter plate under the backwashing effect of clean water. When it overflows the drain port 82, the sewage mixed with a large amount of stains will be discharged to the outside of the equipment through the drain port 82, avoiding the situation where the filter plate 81 is blocked and affects the sewage treatment efficiency. To ensure the sewage treatment flux, the sewage in the filter tank 25 will flow through the core filter assembly 8 and be pumped out through the pumping pipe 72 on the pump 7, and discharged through the outlet pipe 71. It should also be noted that each sewage treatment tank in the equipment is reserved with a sewage pipe 4 for discharging the sewage in the tank, and the sewage pipe 4 is in a normally closed state.

[0027] Embodiment 2: Based on embodiment 1, Figure 2-4 As shown, it also includes an air pipe 2 62, which penetrates from the lower part of the placement groove 26 and then passes out from the lower part of the aerobic pool 24, and is arranged at the bottom of the aerobic pool 24. The gas generated in the fan 6 is transmitted into the aerobic pool 24 through the air pipe 2 61, so as to provide a continuous supply of air for the operation of the aerobic pool 24; the air pipe 1 61 is connected and communicated with the air pipe 2 61, and the gas in the air pipe 2 61 is diverted to the core filter component 8 through the air pipe 1 62. The air pipe 1 61 passes through the lower part of all the filter sheets 81 on the core filter component 8. The gas output from the air pipe 1 61 and the liquid output from the backwash water pipe 92 cooperate to act on the filter sheet 81, thereby improving the activity of the sewage and effectively improving the cleaning efficiency of the filter sheet 81.

[0028] When the fan 6 transports gas through the air pipe 2 62, the air flow in the air pipe 2 62 will be diverted to the core filter component 8 in the filter tank 25 through the air pipe 1 61, and a number of small holes are opened on this section of the air pipe 2 62 in the filter tank 25. The gas enters the sewage in the filter tank 25 through the small holes, forming bubbles, and impacts the filter plate 81. Under the dual effects of clean water and gas impact, the solid dirt on the filter plate 81 is more effectively shaken off, thereby enhancing the backwash effect and reducing the adhesion of dirt on the filter plate 81, thereby ensuring the effective operation of the filter plate 81, reducing the replacement frequency, and increasing the service life of the filter plate 81.

[0029] like Figure 5 and Figure 7 As shown, it also includes a connecting block 10, and the outer sides of the water inlet pipe 5 and the water outlet pipe 71 are symmetrically connected with the connecting block 10 up and down; a clamping block 11, the connecting block 10 is connected with the clamping block 11 through an iron chain, and the inner side of the clamping block 11 is provided with a groove, the groove is wide at the top and narrow at the bottom, when it is sleeved on the outer side of the pipe connection, the inclined surface in the groove will squeeze the interface when the interface is clamped; a screw rod 12, the clamping block 11 on the upper side is screwed with a screw rod 12 front and back; a force rod 13, the upper part of the screw 12 is slidably provided with a force rod 13, the purpose is to tighten the screw 12 without using other tools.

[0030] When the water inlet pipe 5 is connected to sewage, the connected pipe flange is connected to the flange of the water inlet pipe 5 concentrically, and the clamp block 11 is put on the outer side of the flanges of the two pipes. At this time, the flange at the pipe interface is located in the groove of the clamp block 11. The groove is wide at the top and narrow at the bottom, and the outer edges of the two flanges are in contact with the inclined surface in the groove. At this time, the clamp block 11 with the screw 12 is aligned with the clamp block 11 with the threaded hole, and the screw 12 is rotated by the force rod 13 so that the screw 12 is screwed into the threaded hole. When the screw 12 is tightened, the two The clamping block 11 is continuously clamped toward one side of the pipe, and the distance between the two clamping blocks 11 is shortened. The two flanges located in the clamping block 11 are squeezed through the slots in the clamping block 11 and continuously pressed together until they are completely pressed together to complete the connection. Similarly, the water outlet pipe 71 installed on the water pump 7 can be connected to other pipes using components of the same structure and the same steps. By arranging the clamping block 11 and the screw 12 on the pipe, the pipe is docked by extrusion, and there is no need to dock and remove multiple screws 12 on the pipe by other tools as in the conventional way. It is more convenient and quick.

[0031] like Figure 2 , Figure 3 and Figure 6 As shown, a filter element 73 is also included. The filter element 73 is fixedly connected to the left part of the water pump 72. The filter element 73 is composed of a connecting pipe and at least two filter cartridges. The filter cartridges will block the dirt when the sewage is pumped out. The arrangement of multiple filter cartridges is to ensure that the water pressure of the water pumped out by the water pump 7 is normal.

[0032] When the water pump 7 extracts the liquid in the filter tank 25, by installing the filter group element 73 on the water pump pipe 72, the dirt in the sewage can be reduced and extracted by the water pump 7, thereby improving the water quality. At the same time, by setting up multiple filter cartridges, the problem of insufficient water pressure caused by the water pump 7 being affected by the filter element 73 when pumping water can be avoided.

[0033] In a preferred embodiment, a section of air pipe 2 62 in the aerobic tank 24, a section of air pipe 1 61 in the filter tank 25 and the backwash water pipe 92 are all provided with a plurality of holes to ensure that liquid or air flow can be transported into the equipment.

[0034] In a preferred embodiment: the filter sheet 81 is thinner, and the filter sheet 81 is thinner, and the filter sheet structure is obtained by arranging multiple fiber bundles in a mesh with high density and welding them integrally with an external flexible supporting material, so the strength is high, and the flexible supporting material can swing with the fiber flexibility during operation.
