Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment device based on the MPF process and its control system. Background Art

[0002] With the acceleration of the urbanization process and the rapid development of industry, the sewage discharge has increased sharply, causing serious pollution pressure on the environment. Sewage treatment has become an important issue in the field of environmental protection. The MPF process has been widely used in the sewage treatment field due to its high microbial attachment ability and good mass transfer performance.

[0003] However, the sewage treatment device based on the MPF process still faces many challenges and deficiencies in practical applications, mainly reflected in the following aspects. In the traditional MPF process, the aeration method often fails to achieve effective aeration directly for the packing layer, resulting in low efficiency of oxygen transfer to the microbial attachment area, restricting the degradation rate of organic pollutants by the microbial community, and affecting the overall treatment effect. And with the continuous growth of microorganisms on the MPF packing, a dense biofilm gradually forms on the outer layer. While this biofilm enhances the sewage treatment ability, it is also prone to caking, which hinders the effective diffusion of oxygen, nutrients, and metabolites, leading to a slowdown in the metabolism of the microbial community, making it difficult for fresh microorganisms to effectively replace aging cells, reducing the activity and treatment efficiency of the biofilm. Moreover, due to the caking of the biofilm and the difficulty of the aging biofilm to naturally fall off, the internal pores of the MPF packing are gradually blocked, reducing the surface area available for microbial attachment, exacerbating the problem of insufficient aeration, and further restricting the sewage treatment quality. Therefore, there are deficiencies and it cannot meet its usage requirements. Thus, it is necessary to further improve.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sewage treatment device based on the MPF process and its control system are provided, in order to achieve a more practical value purpose. Summary of the Invention

[0020] As a further description of the above technical solution: The adjusting block drives the knocking piece to knock the fixing convex block on the inner wall of the movable ring, prompting the movable ring to generate slight vibration under the action of the elastic corrugated rubber ring, and using this vibration force to shake off the caked biofilm and aging biofilm on the MPF packing body. Through periodic, slight and uniform knocking actions acting on the MPF packing body, it effectively promotes the peeling of the aging biofilm and the formation of the new biofilm, so as to maintain the activity and thickness of the biofilm in the best state.

And by setting sand grains, gravels, and modified biological fillers in the filter layer 13, physical interception of the sewage can be carried out, effectively intercepting suspended solids, particulate matters, and some colloid substances in the sewage, preliminarily purifying the water quality. And as the sewage seeps downward layer by layer in the filter layer 13, smaller particulate matters and impurities can also be gradually intercepted, thus achieving a deep filtration effect and achieving the filtration and removal of impurities in the sewage. At the same time, start the driving pump 22 through the control of the program, use the driving pump 22 to transport the purification agent in the purification tank 21 along the purification main pipe 23 to the primary purification pipe 24, and then shunt through the primary purification pipe 24 and the secondary purification pipe 25, and evenly spray the purification agent through the purification nozzle 26, prompting the purification agent to be mixed with the sewage, and using the purification agent to accelerate the decomposition of pollutants in the sewage, thereby improving the sewage treatment effect; In addition, when sewage is poured into the interior of the tank body 10 and reaches the height of the elastic corrugated rubber ring 32, the input of sewage is stopped. Since the MPF filler body 372 has a large specific surface area and porosity, these characteristics can provide rich attachment areas for microorganisms. Microorganisms can form stable biofilms on the surface of the MPF filler body 372 and use these biofilms to be responsible for degrading organic pollutants in the sewage, thereby enabling the metabolism of the organic matter in the sewage and converting it into harmless substances. Moreover, the MPF filler body 372 can also remove suspended solids, colloidal particles, and some dissolved organic matter in the sewage through physical interception and adsorption. These pollutants are intercepted on the surface or pores of the MPF filler body 372, further reducing the pollutant concentration in the effluent. At the same time, the aerator 40 is started through program control. The aerator 40 transports the outside air into the interior of the tank body 10 along the air delivery pipe 41. The air then passes through the primary air pipe 34, the fixed pipe 35, the secondary air pipe 36, and the filler pipe 371, and finally sprays out through the air holes 3721 on the filler body 372, enabling the air to be released into the sewage in the form of tiny bubbles. Then the bubbles rise in the sewage and come into full contact with the sewage. The oxygen in the bubbles gradually dissolves in the sewage to become dissolved oxygen, enabling aerobic microorganisms to efficiently degrade pollutants such as organic matter and ammonia nitrogen in the sewage under sufficient oxygen conditions. The organic matter in the sewage is oxidized and decomposed into harmless substances such as carbon dioxide and water. And through this setting, direct and uniform aeration of the MPF filler body 372 is achieved, greatly improving the oxygen transfer efficiency, ensuring that the microbial community obtains sufficient oxygen supply, thereby accelerating the degradation process of organic pollutants and significantly enhancing the sewage treatment efficiency; During the operation of the aerator 40, a part of the air flow is transmitted along the air delivery pipe 41 to the ventilation shell 42, and then under the action of the wind force, the movable impeller 51 is driven to rotate. The movable shaft 52 is used to drive the uniform rod 61 to rotate synchronously. During the rotation of the uniform rod 61, under the elastic force of the support spring 64, the movable roller 65 always moves along the plum blossom-shaped limiting groove wall of the adjusting plate 70, thereby driving the adjusting block 63 to reciprocally slide in the movable groove 62 of the uniform rod 61. During the movement of the adjusting block 63, the uniform plate 66 is synchronously driven to move, prompting the uniform plate 66 to perform limited rotation along the trajectory of the plum blossom-shaped limiting groove wall of the adjusting plate 70. The pollutants and other suspended solids in the sewage are fully mixed by the uniform plate 66, making them evenly distributed in the water, so that the sewage mixture inside the tank body 10 is mixed more fully and evenly. And through this setting, the uniform plate 66 forms a reciprocating movement of expansion and contraction during the rotation process, effectively increasing the uniform area, helping to improve the contact opportunity between microorganisms and pollutants, accelerating the degradation process, and further enhancing the sewage treatment efficiency; In addition, during the process of evenly treating sewage by the uniform component 60, the adjustment block 63 drives the percussion component 80 to move synchronously. As the percussion component 80 continuously rotates, the percussion piece 83 comes into contact with the fixed bump 331 on the inner wall of the movable ring 33, thereby realizing the percussion of the fixed bump 331, causing the movable ring 33 to generate slight vibrations under the action of the elastic corrugated rubber ring 32. Meanwhile, when the movable ring 33 vibrates, it drives the MPF packing body 372 to vibrate synchronously. The vibration force can shake off the biofilm hardening and aged biofilm on the MPF packing body 372. Through periodic, slight and uniform percussion actions acting on the MPF packing body 372, it effectively promotes the peeling of the aged biofilm and the formation of the new biofilm, thus maintaining the activity and thickness of the biofilm in the optimal state. And through this setting, it effectively promotes the uniform distribution and metabolic activity of microorganisms on the surface of the MPF packing body 372, avoids the excessive hardening of the biofilm, and reduces the pore blockage phenomenon caused by the hardening of the biofilm. At the same time, it improves the contact efficiency between sewage and microorganisms, accelerates the degradation rate of organic pollutants, and thus greatly improves the overall sewage treatment efficiency; Moreover, during the process of the percussion piece 83 percussing the fixed bump 331, when the percussion force is too large, the percussion piece 83 squeezes the buffer spring 84, and at the same time drives the first magnet block 85 to move towards the second magnet block 86 by means of the movable rod 82. The elastic force of the buffer spring 84 and the repulsive magnetic force between the first magnet block 85 and the second magnet block 86 are used for buffer damping, thereby achieving the purpose of buffering and unloading force. And through this setting, it can effectively prevent the MPF packing body 372 from being damaged due to excessive percussion force, enabling it to quickly react automatically during abnormal percussion, automatically adjust and absorb the excess energy, ensuring that the percussion force is always maintained within a safe range, protecting the integrity and stability of the structure of the MPF packing body 372, and further extending its service life.
