Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0031] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0032] Traditional integrated sewage treatment equipment usually relies on the addition of a large amount of chemical agents to promote the precipitation, oxidation or decomposition of pollutants in the sewage, so as to achieve the purpose of purifying water quality. However, this treatment method not only increases the operating cost, but also may bring problems of chemical agent residues, and then pose a potential risk of secondary pollution to the environment. To solve the above technical problems, the following technical solutions are proposed in this case:

[0033] Referring to Figures 1 to 10 As shown, an intelligent integrated sewage treatment equipment with an MBF seagrass-type biological film filler, its structure includes: an integrated box body 1, and a selection area 2, an anaerobic tank 3, a first-stage anoxic tank 4, a first-stage aerobic tank 5, a second-stage anoxic tank 6, a second-stage aerobic tank 7, and a sedimentation tank 8 that are sequentially connected in series in the integrated box body 1. There is a partition 9 between adjacent reaction tanks, and a flow-through hole 10 for fluid to pass through is formed on the partition 9. The flow-through holes 10 on adjacent partitions 9 are arranged alternately up and down. A filter tank 11 and a clear water tank 12 are also provided behind the sedimentation tank 8 of the integrated box body 1. The sedimentation tank 8 is communicated with the filter tank 11 through an overflow hole at the top, and the bottom of the filter tank 11 is communicated with the clear water tank 12. A number of biological film fillers 13 are installed in the first-stage anoxic tank 4 and the first-stage aerobic tank 5 along the direction of the mixed liquid flow and arranged in parallel. The bottom of the sedimentation tank 8 is connected with a sludge pump 14. The feed end of the sludge pump 14 is connected to the sludge discharge port of the sedimentation tank 8, and the discharge end is connected to the anaerobic tank 3 and an external sludge tank through a sludge return pipe 15 and a sludge discharge pipe 16 respectively. Agitators 17 are provided at the bottoms of the anaerobic tank 3, the first-stage anoxic tank 4, and the second-stage anoxic tank 6;

[0034] It should be noted that the above biological film filler 13 is the biological film filler in the patent application No. CN202510286126.8. By installing a filler support in the first-stage anoxic tank 4 and the first-stage aerobic tank 5, and fixing the above biological film filler parallel to the direction of the fluid movement in the reaction tank;

[0035] The biofilm packing utilizes microorganisms such as nitrifying bacteria and denitrifying bacteria to form a film-like substance on its surface. The packing can be divided into an anaerobic layer, a facultative aerobic layer, an attached water layer, and a flowing water layer from the inside out. Pollutants diffuse from the outer layer to the inner layer step by step through concentration difference diffusion and are decomposed and utilized by microorganisms. Various microorganisms directly or indirectly utilize inorganic and organic pollutants in water as carbon sources and energy sources for growth, metabolism, and reproduction, and achieve a dynamic balance through symbiotic, mutualistic, and predatory relationships. For example, aerobic bacteria in the aerobic layer decompose the organic matter in the attached water layer adsorbed by the biofilm, then anaerobic decomposition occurs in the anaerobic layer, and finally the aged biofilm is washed away through the flowing water layer. This process repeats to achieve the purpose of purifying sewage; metabolic products such as CO2, H2S, and NH3 are discharged from the inner layer to the outer layer and partially converted, while H2O enters the moving water layer through the attached water layer and is discharged with the water; dissolved oxygen (DO) in the water phase diffuses into the biofilm through concentration difference to provide an electron donor for the growth and metabolism of aerobic microorganisms;

[0036] Among them, the water inlet of the integrated box body 1 is connected to the selection area 2, and the water outlet is connected to the clear water tank 12;

[0037] During use, the sewage enters the selection area 2 of the integrated box body 1, and then enters the anaerobic tank 3 through the overflow holes 10 at the bottom. Under anaerobic conditions, the phosphorus-accumulating bacteria will release the phosphorus stored in their bodies, increasing the concentration of phosphorus in the sewage. The dissolved organic matter in the sewage is absorbed and degraded by microorganisms, the BOD5 concentration decreases, and part of the ammonia nitrogen is removed during the microbial synthesis process, but the nitrate nitrogen content remains basically unchanged. Then it enters the first-stage anoxic tank 4 through the overflow holes 10 at the top. Under anoxic conditions, the denitrifying bacteria use the organic matter in the sewage as a carbon source to reduce the nitrate brought in by the internal reflux at the back end to nitrogen gas, which is released into the atmosphere. Then it enters the first-stage aerobic tank 5 through the overflow holes 10 at the bottom. Under aerobic conditions, the nitrifying bacteria convert the ammonia nitrogen in the sewage into nitrite and then further into nitrate. The phosphorus-accumulating bacteria use the PHB (poly-β-hydroxybutyrate) stored in their bodies to excessively absorb the phosphorus in the sewage, forming polyphosphate, thereby reducing the total phosphorus concentration. The aerobic microorganisms further decompose the remaining organic matter, making the BOD5 concentration further decrease. Then it enters the second-stage anoxic tank 6 through the overflow holes 10 at the top for further denitrification reaction. Then it enters the second-stage aerobic tank 7 through the overflow holes 10 at the bottom for further nitrification reaction. Then it enters the sedimentation tank 8 through the overflow holes 10 at the top for uniform water distribution into the bottom of the sedimentation tank 8. After the activated sludge is sedimented, the sludge pump 14 transports part of the internal reflux in the sedimentation tank 8 to the anaerobic tank 3 through the sludge return pipe 15. At the same time, part of the sludge in the anaerobic tank 3 enters the first-stage anoxic tank 4 along with the flow of the sewage, thereby supplementing the activated sludge in the anaerobic tank 3 and the first-stage anoxic tank 4. The sludge pump 14 transports another part of the sludge to the external sludge tank through the sludge discharge pipe 16 for concentration and external transportation treatment. The clear water above the sedimentation tank 8 enters the filter tank 11 through the overflow holes provided at the top. The filter tank 11 is equipped with filter media and is discharged after filtration and disinfection in the clear water tank 12;

[0038] Moreover, stirrers 17 are provided at the bottoms of the anaerobic tank 3, the first-stage anoxic tank 4, and the second-stage anoxic tank 6. Through continuous and uniform stirring, the circulation of the water flow in the tank is effectively promoted, ensuring full contact between the sewage and microorganisms in the tank, thereby improving the biodegradation efficiency. In the anaerobic tank 3, the stirrer helps maintain uniform mixing under anaerobic conditions and promotes the activities of anaerobic microorganisms and the degradation of organic matter in the sewage. In the first-stage anoxic tank 4 and the second-stage anoxic tank 6, the stirrer helps create a suitable anoxic environment, promotes the denitrification process, removes the nitrogen source in the water, not only improves the efficiency of water quality treatment in the tank, but also reduces the accumulation of sediment and prevents excessive accumulation of sludge at the bottom of the tank.

[0039] Therefore, in this application, by combining the enhanced AAO anaerobic-anoxic-aerobic process and the biofilm fillers arranged in parallel, in the first-stage anoxic tank 4 and the first-stage aerobic tank 5, the sewage is in full contact with the biofilm fillers, forming a good biofilm reaction zone, effectively degrading the organic pollutants in the sewage. In addition, by using a sludge pump to return the sludge in the sedimentation tank to the anaerobic tank 3 and the first-stage anoxic tank 4, not only is the degradation of organic matter and denitrification in the anaerobic tank and the anoxic tank further enhanced, but also the sludge concentration is reduced, significantly reducing the production amount of surplus sludge. No drugs need to be added during the whole process, effectively avoiding the secondary pollution problem that may be brought by drug residues. At the same time, the water treatment efficiency and water quality are improved, and the effluent water quality can stably reach the first-class A standard, and even can reach the water quality of the fourth category of surface water level.

[0040] Further, aeration devices 18 are provided at the bottoms of the first-stage aerobic tank 5 and the second-stage aerobic tank 7. The aeration device 18 includes aeration discs 19 respectively installed at the bottoms of the first-stage aerobic tank 5 and the second-stage aerobic tank 7, and a blower 20 connected to the two aeration discs 19. The blower 20 transports air to the aeration discs 19 through air pipes, providing sufficient oxygen in the tank to ensure the smooth progress of the nitrification reaction. The aeration device not only ensures sufficient dissolved oxygen, promotes the growth and reproduction of nitrifying bacteria, but also strengthens the mixing and degradation of the sewage in the tank, effectively accelerating the degradation process of the organic matter in the sewage, improving the sewage treatment efficiency, and at the same time effectively improving the water quality.

[0041] Comet-shaped filter media 21, fiber filter balls 22, and pebble layers 23 are filled in the filter tank 11 from top to bottom in sequence. A multi-stage filter media configuration is adopted. First, the comet-shaped filter media 21 is located at the top of the filter tank, having good water flow distribution performance and high filtration accuracy, effectively removing large particulate impurities and suspended matters in the water. Then, the fiber filter ball 22 layer further improves the filtration effect, intercepts smaller particulate matters, and enhances the adsorption and capture ability for micro-pollutants. Finally, the pebble layer 23 is located at the bottom of the filter tank, mainly playing a role in supporting and regulating the water flow, and at the same time further preventing the clogging of the filter media layer, ensuring the stability and high efficiency of the filtration process. Through the multi-level and composite filter media configuration, this filter tank can effectively improve the water quality, remove impurities and suspended matters in the water, and ensure that the effluent water quality reaches a higher standard.

[0042] An inlet grille 24 for filtering large particulate impurities is installed at the water inlet of the selection area 2, thereby avoiding the blockage of pumps and pipelines in the integrated box body caused by large particulate suspended matters in the sewage.

[0043] The inlet grille 24 includes a water tank 25 communicating with the top of the selection area 2. A basket grille 26 is arranged in the water tank 25. A number of filter holes are formed on the surface of the basket grille 26. The side wall of the water tank 25 is penetrated and connected with a water inlet pipe 27 and an overflow pipe 28. The water inlet pipe 27 passes through the water tank 25 and extends downward from the top of the basket grille 26. The overflow pipe 28 passes through the water tank 25 and communicates with one end of the side wall of the basket grille 26 close to the top. Therefore, sewage enters the basket grille 26 through the water inlet pipe 27, intercepts large particle impurities in the sewage, and after filtration, enters the selection area 2 through the discharge port at the bottom of the water tank 25. When the water level is too high, the overflow pipe 28 will automatically guide the excess water to flow out to prevent the water tank from overflowing.

[0044] An ultraviolet disinfection device 29 is arranged in the clear water tank 12. The ultraviolet disinfection device is composed of a lamp holder and a number of ultraviolet lamps arranged vertically in a ring on the lamp holder, which can effectively kill bacteria, viruses and other microorganisms in the water, so as to thoroughly disinfect the clear water.

[0045] The integrated box body 1 is also provided with an equipment room 30, and the sludge pump 14 and the fan 20 are respectively arranged in the equipment room 30.

[0046] An air washing device 31 and a backwashing device 32 are arranged in the filter tank 11. The air washing device 31 conveys air to the bottom of the filter tank 11 through an air pipe by an air pump. With the impact force of the air flow, it can effectively loosen and remove impurities and sediments in the filter medium, avoid clogging of the filter medium, and thus maintain the filtration efficiency. At the same time, the backwashing device 32 conveys clear water to the filter tank 11 through a water pipe by a water pump, and backwashes the filter medium through the reverse water flow to further clean and restore the filtration capacity of the medium.

[0047] The integrated box body 1 is welded by high-strength steel plates, and the inner and outer surfaces of the integrated box body 1 are subjected to anti-corrosion treatment, ensuring the firmness and durability of its structure. The anti-corrosion treatment effectively resists the erosion of water quality, climate change and chemical substances on the surface of the box body, extends the service life of the box body, and ensures its stability and safety during long-term operation.

[0048] Those not detailed in this utility model are all well-known technologies to those skilled in the art.

[0049] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
