Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment equipment based on an MPF process and a control system thereof. BACKGROUND

[0002] Sewage treatment has become an important issue in the field of environmental protection. The MPF process has been widely used in the field of sewage treatment due to its efficient microbial attachment capacity and good mass transfer performance.

[0003] However, the sewage treatment equipment based on the MPF process still faces many challenges and deficiencies in practical application, mainly in the following aspects. In the traditional MPF process, the aeration mode often fails to achieve effective aeration directly to the filler layer, resulting in low efficiency of oxygen transfer to the microbial attachment area, limiting the degradation rate of organic pollutants by the microbial community, and affecting the overall treatment effect. With the continuous growth of microorganisms on the MPF filler, a dense biofilm is gradually formed on the outer layer. This biofilm, while enhancing the sewage treatment capacity, is prone to hardening, thereby hindering the effective diffusion of oxygen, nutrients and metabolic products, slowing down the metabolism of the microbial community, and making it difficult for fresh microorganisms to effectively replace aging cells, reducing the activity and treatment efficiency of the biofilm. Moreover, due to the hardening of the biofilm and the difficulty of natural shedding of the aging biofilm, the internal pores of the MPF filler are gradually clogged, reducing the surface area available for microbial attachment and exacerbating the problem of insufficient aeration, further limiting the quality of sewage treatment. Therefore, there are deficiencies that cannot meet the use requirements, and it is necessary to further improve.

[0086] Working principle: in use, the sewage is discharged into the inside of the tank body 10 through the water inlet interface 11, the sewage is discharged into the bottom of the tank body 10 through the filter layer 13, and the sand, gravel and modified biological filler are arranged in the filter layer 13, so that the sewage can be physically intercepted, the suspended solids, particulate matter and part of the colloidal substances in the sewage can be effectively intercepted, the water quality is preliminarily purified, and the smaller particulate matter and impurities can also be gradually intercepted as the sewage infiltrates layer by layer in the filter layer 13, so as to realize the deep filtration effect and achieve the filtration and removal of impurities in the sewage; at the same time, the driving pump 22 is started by the program control, the purification agent in the purification tank 21 is transmitted to the primary purification pipe 24 through the purification main pipe 23 by the driving pump 22, and then is shunted through the primary purification pipe 24 and the secondary purification pipe 25, the purification agent is uniformly sprayed out through the purification spray head 26, the purification agent and the sewage are mixed with each other, the decomposition of the pollutants in the sewage is accelerated by the purification agent, so as to improve the sewage treatment effect;

[0087] Furthermore, when the sewage is filled into the inside of the tank 10 and reaches the height of the elastic corrugated rubber ring 32, the input of the sewage is stopped, and because the MPF filler body 372 has a large specific surface area and porosity, these characteristics can provide a rich attachment area for microorganisms, and the microorganisms can form stable biofilms on the surface of the MPF filler body 372, and utilize these biofilms to be responsible for degrading organic pollutants in the sewage, so as to be able to metabolize the organic matter in the sewage and convert it into harmless substances, and the MPF filler body 372 can also remove suspended solids, colloidal particles and part of dissolved organic matter in the sewage through physical interception and adsorption, and these pollutants are intercepted on the surface or in the pores of the MPF filler body 372, further reducing the pollutant concentration in the effluent; At the same time, the aerator 40 is started by program control, and the aerator 40 is used to transport the air outside along the aeration pipe 41 into the inside of the tank 10, and the air is sprayed out through the aeration holes 3721 on the filler body 372 along the primary air pipe 34, the fixed pipe 35, the secondary air pipe 36 and the filler pipe 371, and finally the air is released in the form of small bubbles into the sewage, so that the bubbles rise in the sewage and fully contact with the sewage, and the oxygen in the bubbles is gradually dissolved in the sewage to become dissolved oxygen, so that the aerobic microorganisms can efficiently degrade the organic matter and ammonia nitrogen and other pollutants in the sewage under sufficient oxygen conditions, and the organic matter in the sewage is oxidized and decomposed into carbon dioxide and water and other harmless substances, and the direct and uniform aeration of the MPF filler body 372 is realized by this setting, which greatly improves the oxygen transfer efficiency and ensures that the microbial community obtains sufficient oxygen supply, thereby speeding up the degradation process of organic pollutants and significantly improving the sewage treatment efficiency.

[0088] And in the process of operation of the aerator 40, a part of the airflow is transmitted along the aeration pipe 41 into the air casing 42 by the aeration pipe 41, and then the movable impeller 51 is driven to rotate under the action of the wind force, and the uniform rod 61 is synchronously rotated by the movable shaft 52, and the movable roller 65 is always moved along the plum blossom-shaped limiting groove wall of the adjusting plate 70 under the elastic force of the supporting spring 64 in the process of rotation of the uniform rod 61, thereby driving the adjusting block 63 to reciprocate in the movable groove 62 of the uniform rod 61, and the uniform plate 66 is moved synchronously in the process of movement of the adjusting block 63, which drives the uniform plate 66 to limit and rotate along the plum blossom-shaped limiting groove wall trajectory of the adjusting plate 70, and the pollutants and other suspended solids in the sewage are fully mixed by the uniform plate 66, so that they are uniformly distributed in the water, and the mixture of the sewage in the inside of the tank 10 is more fully and uniformly mixed, and the uniform plate 66 is formed by the setting to form a reciprocating movement in the process of rotating rotation, which effectively increases the uniform area, helps to improve the contact opportunity of microorganisms and pollutants, speeds up the degradation process, and further improves the sewage treatment efficiency.

[0089] In addition, in the process of uniformly treating the sewage, the adjusting block 63 drives the knocking assembly 80 to move synchronously, and as the knocking assembly 80 continuously rotates, the knocking piece 83 is in contact with the fixed protrusions 331 on the inner wall of the movable ring 33, thereby knocking the fixed protrusions 331, causing the movable ring 33 to vibrate slightly under the action of the elastic corrugated rubber ring 32, and the movable ring 33 vibrates synchronously with the MPF filler body 372, and the vibration force can shake off the hardened and aged biofilm on the MPF filler body 372, and through the periodic, slight and uniform knocking action, the MPF filler body 372 is acted on, effectively promoting the peeling of the aged biofilm and the formation of the new biofilm, so as to maintain the activity and thickness of the biofilm in the best state, and effectively promote the uniform distribution and metabolic activity of the microorganisms on the surface of the MPF filler body 372, avoid the excessive hardening of the biofilm, and reduce the pore blockage phenomenon caused by the hardening of the biofilm, and improve the contact efficiency of the sewage and the microorganisms, accelerate the degradation rate of the organic pollutants, and thus greatly improve the sewage treatment efficiency.

[0090] When the knocking force is too large in the process of the knocking piece 83 knocking the fixed protrusions 331, the knocking piece 83 is pressed against the buffer spring 84, and the movable rod 82 drives the first magnet block 85 to move towards the second magnet block 86, and the buffer spring 84 and the magnetic repulsion between the first magnet block 85 and the second magnet block 86 are used for buffering and damping, so as to achieve the purpose of buffering and unloading, and through the above-mentioned arrangement, the damage of the MPF filler body 372 caused by the excessive knocking force can be effectively prevented, so that the MPF filler body 372 can automatically react, automatically adjust and absorb the excess energy when the knocking is abnormal, so as to ensure that the knocking force is always maintained within a safe range, protect the integrity and stability of the structure of the MPF filler body 372, and further improve the service life.
