Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to an environmentally friendly microbial sewage treatment system. Background Art

[0002] Microbial wastewater treatment is to decompose and transform pollutants in wastewater by utilizing the metabolic function of microorganisms to achieve the purpose of purifying water quality.

[0003] There are many types of existing microbial treatment devices, including an environmentally friendly microbial sewage treatment system disclosed in publication number CN116199348B. The device optimizes the decomposition process of irritating odors and harmful components in sewage by the biological treatment tank through the mutual cooperation of various internal components, thereby improving the sewage treatment efficiency. However, in actual applications, the microorganisms in sewage may be affected due to the following reasons;

[0004] When the concentration of pollutants in sewage is too high, microorganisms cannot treat sewage normally, mainly because the load of pollutants exceeds the processing capacity of microorganisms, resulting in their metabolic capacity being unable to meet the degradation needs. Under normal circumstances, microorganisms convert organic and inorganic substances in sewage into harmless substances through metabolism, but when the concentration of pollutants is too high, microorganisms cannot promptly treat excess organic or toxic substances. Specifically, when the concentration of pollutants in sewage is much higher than the degradation capacity of microorganisms, microorganisms cannot quickly decompose these pollutants, resulting in their accumulation and inhibiting the metabolic rate of the microbial community.

[0005] Most sewage treatment microorganisms require sufficient dissolved oxygen for aerobic respiration, and excessive pollutant loads often lead to rapid oxygen consumption, causing the dissolved oxygen concentration to drop, affecting the activity of the microorganisms; microbial growth and metabolism require a certain proportion of nutrients such as nitrogen and phosphorus. If the sewage contains insufficient supply of these necessary nutrients, the microorganisms cannot obtain sufficient nutrition, affecting their metabolism and treatment efficiency; high concentrations of pollutants may lead to the inhibition or death of certain microbial populations, disrupt the balance of the microbial community, and affect the overall treatment capacity of the system. Summary of the invention

[0022] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0023] First, the air is intermittently sprayed toward the sponge carrier through the various air outlet pipes and nozzles, so that the sponge carrier is dynamically swung in the microbial treatment area, making it difficult for mud and sand on the surface of the sponge carrier to deposit. The dynamic change of the ejected airflow can effectively break up the sludge deposited on the surface of the sponge carrier, reduce mud and sand accumulation and blockage, and at the same time, the water flow and bubbles brought by the ejected airflow can enhance the transfer efficiency of oxygen, nutrients and waste in the water. Stronger material transfer helps to promote the activity of microorganisms, and can also accelerate the degradation and transformation of harmful substances in sewage.

[0024] Second, by adding nutrients and new microorganisms required by the microorganisms into the top frame respectively, the pressing plate drives the slide bar to drive the extrusion plate to slide down in the top frame in an airtight manner, extruding the nutrients and new microorganisms, and injecting the nutrients and microorganisms into the sponge carrier through the second connecting pipe;

[0025] Adding nutrients keeps the microorganisms active, and the newly added microorganisms can effectively improve the ability to degrade organic pollutants in sewage, accelerate the decomposition of pollutants by microorganisms, and improve overall treatment efficiency.

[0026] Thirdly, by conveying part of the sewage into a transparent measuring barrel and allowing the sewage to settle in the transparent measuring barrel, the light irradiated by the irradiation lamp will penetrate the transparent measuring barrel and be received by the light detection element. The sewage entering the transparent measuring barrel needs to be sewage that has been effectively filtered by microorganisms. Therefore, the sewage should maintain a certain clarity after settling for a certain period of time after being filtered by microorganisms. When the electrical signal generated by the light detection element does not change or the change trend is not large within the set sedimentation time, it is determined that the filtered sewage has not achieved the required filtering effect. The sewage is filtered to allow the sediment to remain in the transparent measuring barrel and heated to completely burn the sediment. The ratio of organic matter to inorganic matter before and after the sediment is heated is calculated through the existing calculation method to determine whether the sewage is effectively filtered by microorganisms.

[0027] Fourth, when the sponge carrier is deformed and sinks due to the thickening of the biofilm caused by the accumulation of microorganisms, the rotating shaft is driven to rotate, and the wound rubber belt winds the sinking sponge carrier together with the outer wall of the rotating shaft. In the process of winding the rubber belt, the external water source is transported into the pipeline through a high-pressure water pump, and the cleaning water is transported into the water spray pipe through the pipeline and then sprayed out to spray and wash both sides of the sponge carrier, and the biofilm attached to the sponge carrier is sprayed and sucked off.

[0028] Fifth, by pouring the wastewater into the first fixed frame, turning on the rotating drive member to drive the shaft to rotate and at the same time rotating the transmission belt, the larger particles and dirt in the wastewater will be driven into the external box through the transmission belt, and the remaining wastewater will flow into the microbial treatment area through the flow gap, thereby filtering out the larger particles and impurities in the wastewater and avoiding them from entering the microbial treatment area.

[0055] The working principle of the present invention is as follows:

[0056] 1. Filtering sewage: Pour sewage into the first fixed frame 301, open the rotating drive member 303, drive the shaft to rotate, and the rotating shaft will drive the transmission belt 302 to rotate. The larger particles and dirt in the sewage will be driven into the external box 304 through the transmission belt 302, and the sewage will flow into the microbial treatment area through the flow gap. The sewage then enters the microbial treatment area, and the microorganisms attached to the sponge carrier 102 decompose the organic pollutants (including organic carbon sources) in the sewage into less inorganic substances through their metabolism, thereby purifying the sewage. The purified sewage is discharged outward through the outlet (when microorganisms treat sewage, they mainly rely on organic matter in the sewage as a nutrient source for metabolism and reproduction, but in some cases, the nutrients in the sewage may not be sufficient to support the normal growth of microorganisms, or the concentration of sewage is too high, resulting in the inability of microorganisms to effectively treat. At this time, it can be considered to improve the growth environment of microorganisms and improve the treatment effect by adding additional nutrients);

[0057] 2. Make the sponge carrier 102 dynamic to reduce the attachment of sediment. When the sewage enters the microbial treatment area, some fine sediment will enter the microbial treatment area. The external gas injection device continuously injects gas into each pneumatic rotary joint 201 through the ventilation pipe 203, and the pneumatic rotary joint rotates. The pneumatic rotary joint 201 rotates continuously to connect the output air hole with each air inlet hole in turn, so that the gas input by the gas injection device is injected into each air delivery pipe 204 through the air inlet hole, and enters the air outlet pipe 206 through the first connecting pipe 205 and then flows out from the nozzle. The air is ejected from the outlet 207, so that each outlet pipe 206 and the nozzle 207 are sequentially discharged and sprayed toward the sponge carrier 102, so as to push the sponge carrier 102 to swing, so that the sponge carrier 102 is dynamically swung in the microbial treatment area. The dynamic change of the ejected airflow can effectively break up the sludge deposited on the surface of the sponge carrier 102, reduce the accumulation of silt and blockage, and at the same time, the sewage flow brought by the ejected airflow and the bubble effect generated can enhance the oxygen in the water, which helps to promote the activity of microorganisms and also accelerate the degradation and transformation of harmful substances in sewage.

[0058] 3. Clean the sponge carrier 102: When the sewage is treated by microorganisms, the microorganisms will attach to the surface of the sponge carrier 102 to form a biological filter membrane. As the filtration time increases, the microorganisms will accumulate and make the biofilm thicker, affecting the circulation of water, resulting in increased water flow resistance in some areas of the microbial treatment area, and even blockage. The material of the sponge carrier 102 is relatively soft, and the long-term accumulation of biofilm will cause the sponge carrier 102 to bend and deform as a whole. As the biofilm on the surface of the sponge carrier 102 thickens and the pores are blocked, the channel for sewage flow will become narrow or uneven, and the sewage cannot pass through the sponge carrier 102 smoothly, resulting in a slow flow rate of sewage and filtration. The efficiency is reduced, and the sliding column 112 and the top plate 115 are provided to support the bottom of the sponge carrier 102. When the sponge carrier 102 is deformed and sinks due to the accumulation of microorganisms and the thickening of the biofilm, the deformed sponge carrier 102 will drive the top plate 115 and the sliding column 112 to compress the spring 114 and drive the U-shaped telescopic frame 111 to slide, and the displacement monitoring element 113 will be squeezed by the downward movement of the top plate 115 (there is a certain distance between the top plate 115 and the displacement monitoring element 113. When the sponge carrier 102 is severely deformed due to the thickness of the biofiltration membrane, the top plate 115 will be driven to descend and the displacement monitoring element The controller controls and opens the voltage input to the driving assembly 106 and the electromagnetic clutch through the electrical signal generated by the displacement monitoring element 113 to drive the output end of the motor to rotate, and drives the rotating shaft 103 to rotate through the short shaft, the electromagnetic clutch at the corresponding position and the gear belt. The wound rubber belt 104 winds the sinking sponge carrier 102 together with the outer wall of the rotating shaft 103. The rubber rope 108 is stretched during the winding process, and the external water source is transported into the pipeline through the high-pressure water pump, and the cleaning water is then transported into the water spray pipe 105 by the pipeline and sprayed out from the spray hole to clean the two sides of the sponge carrier 102. Spray washing is performed to clean the biofilm attached to the sponge carrier 102. When the sponge carrier 102 is completely wound onto the outer wall of the rotating shaft 103, the sealing plate 109 blocks the partition 101 close to the rotating shaft 103, and the cleaning water is retained on one side of the partition 101 to avoid mixing with the sewage being filtered, so as to facilitate subsequent cleaning (during cleaning, the cleaned sewage and impurities can be extracted and collected together). After cleaning, the voltage supplied to the motor is disconnected by the controller, and the stretched rubber rope 108 will retract, driving the sponge carrier 102 to move back to the cleaning area, so as to reuse the sponge carrier 102;

[0059] 4. Detect the sewage treatment effect: The controller controls the power supply on the first solenoid valve 502 to open the valve core of the first solenoid valve 502, allowing part of the filtered sewage to enter the transparent measuring barrel 503 through the delivery pipe 501 (the filtered sewage entering the transparent measuring barrel 503 is the sampled sewage, and the weight of the sampled sewage needs to be calculated based on the total amount of sewage discharged into the microbial treatment area). The weight of the filtered sewage entering the transparent measuring barrel 503 is detected by the weight measuring element 508. When the weight reaches the standard sampling weight set by the total sewage flow rate, the controller will control the closing of the first solenoid valve 502, and turn on the irradiation lamp 512 and the light detection element 513 through the controller. The light irradiated by the irradiation lamp 512 Light will penetrate the transparent measuring barrel 503 and be received by the light detecting element 513 (the sewage entering the transparent measuring barrel 503 is sewage that has been effectively treated by microorganisms, and should not contain a large amount of organic and inorganic substances. Therefore, the sewage should maintain a certain clarity after settling for a certain period of time after being treated by microorganisms). The settling time of the sewage in the transparent measuring barrel 503 is set. During the settling time, the resistance value generated by the light irradiated by the irradiation lamp 512 and received by the light detecting element 513 increases from small to large. If the resistance value generated by the light detecting element 513 does not change or the change trend is not obvious within the set settling time, it should be determined that the filtered sewage has not achieved the required treatment effect;

[0060] After the sedimentation effect after the sewage filtration is detected, the second solenoid valve 510 is opened by the controller to discharge the sewage sample in the transparent measuring barrel 503. The filter cotton provided can prevent the sediment from flowing out with the sewage. After the sewage is discharged, the heating element 515 is turned on by the controller to heat the transparent measuring barrel 503 (the heating temperature needs to be maintained at about 550°C) to heat the sediment remaining in the transparent measuring barrel 503. The sediment is completely burned, and the organic matter in the sediment will be oxidized and burned, while the inorganic matter such as ash will be retained. In this process, the weight measuring element 508 provided will record the sediment. The weight before and after heating is used to calculate the ratio of organic matter to inorganic matter in the sediment before and after heating through the existing calculation method, so as to determine whether the sewage is effectively treated, thereby judging whether the sewage is effectively treated in the microbial treatment area. It should be noted that the filter cotton needs to be replaced after heating, and the weight measurement of the weight measuring element 508 needs to be calibrated regularly. The heating temperature of the heating element 515 needs to be adjusted according to the different organic matter contained in different sewage after treatment (for example, some special organic matter that is difficult to burn completely will interfere with the calculation of the ratio of organic matter to inorganic matter, and the heating temperature needs to be adjusted);

[0061] Through the above-mentioned test of sewage filtration effect, it can be concluded that the sewage has not been effectively biologically treated after passing through the microbial treatment area. The following operations can be taken:

[0062] First, the aeration efficiency of the aeration disturbance assembly 2 can be improved by increasing the output power of the gas injection device, thereby increasing the oxygen content in the microbial treatment area;

[0063] Second, by adding nutrients (such as nitrogen, phosphorus and other elements) required by the microorganisms into the top frame 401, by pressing the pressing plate 405 to drive the slide bar 404 to drive the extrusion plate 406 to slide down in an airtight manner in the top frame 401, the nutrients are squeezed, and the nutrients are injected into the sponge carrier 102 through the second connecting pipe 407 (nutrients (including nitrogen, phosphorus, etc.) are key components for microorganisms to synthesize cell substances. In the process of using organic pollutants to obtain energy, microorganisms need nutrients to build their own cell structures. For example, nitrogen is an important raw material for synthesizing proteins and nucleic acids, and phosphorus is a key component for synthesizing biological molecules such as phospholipids. Microorganisms use the energy provided by organic pollutants to assimilate nutrients into their own components, thereby promoting the growth and reproduction of microorganisms);

[0064] Third, new microorganisms are also added into the top frame 401. The new microorganisms are squeezed into the sponge carrier 102 through the above operation. It should be noted that the addition of new microorganisms needs to match the previous microorganisms so as to maintain an ecological balance between the microorganisms, resulting in competition, inhibition or extinction of the original microorganisms;

[0065] Through the above operations, the oxygen content is increased and nutrients are added to keep the microorganisms active. The added new microorganisms can effectively improve the ability to degrade organic pollutants in sewage. This method can accelerate the decomposition of pollutants by microorganisms and improve the overall treatment efficiency, especially in systems with high pollution loads or large treatment needs.
