Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of wastewater treatment technology, and particularly to a wastewater treatment method, system, and storage medium. Background Technology

[0002] In the wastewater treatment process, organic pollutants in wastewater are degraded by biological fluidized beds. The dissolved oxygen content affects the degradation efficiency of organic pollutants by the microbial community in the biological fluidized bed. The biological fluidized bed is filled with a carrier (such as suspended packing or particulate carrier), and the microbial community will attach to the surface of the carrier. If the carrier settles and accumulates, the microbial community at the bottom of the biological fluidized bed will die due to pressure and lack of nutrients, thereby reducing the degradation efficiency of organic pollutants by the biological fluidized bed.

[0003] Existing technologies, which artificially regulate the aeration of biological fluidized beds, are prone to large fluctuations in dissolved oxygen content and excessive carrier sedimentation, which affect the degradation efficiency of biological fluidized beds for organic pollutants.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0023] In the wastewater treatment process, organic pollutants in wastewater are degraded by biological fluidized beds. The dissolved oxygen content affects the degradation efficiency of organic pollutants by the microbial community in the biological fluidized bed. The biological fluidized bed is filled with a carrier (such as suspended packing or particulate carrier), and the microbial community will attach to the surface of the carrier. If the carrier settles and accumulates, the microbial community at the bottom of the biological fluidized bed will die due to pressure and lack of nutrients, thereby reducing the degradation efficiency of organic pollutants by the biological fluidized bed.

[0024] Existing technologies, which artificially regulate the aeration of biological fluidized beds, are prone to large fluctuations in dissolved oxygen content and excessive carrier sedimentation, which affect the degradation efficiency of biological fluidized beds for organic pollutants.

[0025] To address the aforementioned problems, this application provides a wastewater treatment method, system, and storage medium.

[0026] This application provides a wastewater treatment method, system, and storage medium, which will be described in detail in the following embodiments.

[0027] like Figure 1 As shown, this embodiment of the invention provides a wastewater treatment method applied to a water pollution treatment device. The water pollution treatment device includes a first treatment module, a second treatment module, and a third treatment module. The second treatment module includes a fluidized bed unit and an air intake unit, and the air intake unit is connected to the fluidized bed unit. The wastewater treatment method includes: S100. The wastewater to be treated is pretreated by the first processing module to obtain the first treated water.

[0028] Specifically, refer to Figure 2 The first treatment module of this application includes a collection tank, an equalization tank, and a physicochemical fluidized bed. After the production wastewater is collected in the collection tank, its pH and the uniformity of organic pollutants are adjusted in the equalization tank. The adjusted wastewater is then discharged into the physicochemical fluidized bed for impurity precipitation. Appropriate reagents are added via a dosing device to adsorb metal ions and silt from the wastewater or to induce chemical reactions, causing them to precipitate at the bottom of the physicochemical fluidized bed. The precipitated sludge is then transported to a sludge thickening tank for concentration, and finally treated in the sludge treatment workshop. The production wastewater treated by the physicochemical fluidized bed is the first treated water.

[0029] S200. Obtain the fluidization parameters of the fluidized bed unit, wherein the fluidization parameters indicate the temperature spectrum, dissolved oxygen content, sediment height and bacterial species of the fluidized bed unit.

[0030] Specifically, multiple temperature sensors (such as thermocouple sensors) are evenly installed according to the structural characteristics of the fluidized bed (e.g., bottom, middle, top, and edge areas). The sensors are fixed in positions that do not affect the fluidization of the carrier and can directly contact the water to ensure detection accuracy. The temperature values ​​of each sensor are synchronously recorded through a data acquisition module. The acquisition frequency is set as needed, and data is continuously collected for a period of time to obtain dynamic temperature change data for each area. The position coordinates of each sensor are correlated with the corresponding temperature data, and a three-dimensional temperature map is generated using data visualization software (such as a BIM system or professional data analysis tools). The map uses different colors and / or numbers to distinguish between high and low temperatures (e.g., red represents high temperature, blue represents low temperature), visually presenting the temperature distribution within the fluidized bed, the location of localized high or low temperature areas, and the range of temperature differences.

[0031] Using a layout logic corresponding to the temperature sensors, dissolved oxygen sensors (such as fluorescence-based dissolved oxygen sensors) are installed at different heights and radial positions in the fluidized bed, focusing on covering the core fluidized bed region, the area near the bottom sediment, and the inlet and outlet ports to ensure coverage of the main activity range of the bacterial community. Dissolved oxygen values ​​from each sensor are recorded simultaneously with temperature data acquisition at the same frequency, along with the water temperature at the time of acquisition. The raw dissolved oxygen data is calibrated based on environmental parameters such as water temperature and air pressure (to eliminate environmental interference), and finally integrated into dissolved oxygen distribution data corresponding to the temperature spectrum location. This data can be superimposed on the temperature spectrum or used to create a separate dissolved oxygen content distribution map.

[0032] Non-contact detection equipment (such as ultrasonic level gauges and radar sensors) is installed at the corresponding position on the top of the fluidized bed. The distance between the bottom sediment surface and the sensor is detected by emitting sound waves or electromagnetic waves. Combined with the depth of the fluidized bed, the sediment height is calculated.

[0033] The types of microorganisms can be obtained by analyzing carrier samples or mixed water samples collected from different areas of the fluidized bed, or by analyzing the types of microorganisms added to the fluidized bed unit. The specific method of acquisition is not limited here.

[0034] S300. The air intake mode of the air intake unit is controlled according to the fluidization parameters so that the fluidized bed unit fluidizes the first treated water to obtain the second treated water. The temperature spectrum, dissolved oxygen content and sediment height of the fluidized bed unit correspond to the bacterial species.

[0035] Specifically, the temperature spectrum should show a suitable temperature range for the bacterial community (e.g., 20-30℃ for aerobic bacteria, 15-25℃ for anaerobic bacteria), without obvious high or low temperature regions; the dissolved oxygen content should match the aerobic properties of the bacterial community; and the sediment height should be below a safe threshold to avoid carrier accumulation that could compress the bacterial community's living space. By controlling the air intake mode of the air intake unit, the correspondence between the temperature spectrum, dissolved oxygen content, sediment height, and bacterial species can be maintained or restored, ensuring the stability of the bacterial community.

[0036] In some optional embodiments, the fluidized bed unit includes a first biological fluidized bed and a second biological fluidized bed; controlling the air intake mode of the air intake unit according to the fluidization parameters, so that the fluidized bed unit fluidizes the first treated water to obtain the second treated water, includes: S310. Control the first mode of the air intake unit according to the first spectrum, first content, first height and first type of the first biological fluidized bed. The first spectrum represents the temperature spectrum of the first biological fluidized bed, the first content represents the dissolved oxygen content of the first biological fluidized bed, the first height represents the sediment height of the first biological fluidized bed, and the first type represents the bacterial community type of the first biological fluidized bed. Specifically, the aeration oxygen supply basis is determined with the first type (the bacterial community of the first biological fluidized bed, such as aerobic heterotrophic bacteria) as the core (e.g., aerobic bacteria require high-power continuous aeration); the heating power and aeration uniformity are adjusted in conjunction with the first spectrum (temperature distribution of the first biological fluidized bed) (e.g., heating and air supply at low temperatures, and increasing aeration heat dissipation at high temperatures); the aeration power is calibrated according to the first content (dissolved oxygen content of the first biological fluidized bed) (increase power to supplement oxygen in the absence of oxygen, and decrease power in the presence of excess oxygen); and the aeration direction and impact intensity are optimized with reference to the first height (sediment height of the first biological fluidized bed) (strong aeration at the bottom is used to disperse the sediment if it is too thick).

[0037] S320. After controlling the air intake unit to aerate the first biological fluidized bed in the first mode, the first treated water is subjected to first fluidization treatment through the first biological fluidized bed to obtain first fluidized water. Specifically, the air intake unit aerates the first biological fluidized bed in the first mode. The suitable aeration environment of the first biological fluidized bed stabilizes the activity of the bacterial community, fully degrading pollutants (such as organic matter and ammonia nitrogen) in the first treated water. After treatment by the first bed, the pollutant concentration in the wastewater is significantly reduced, forming the first fluidized water.

[0038] S330. Control the second mode of the air intake unit according to the second spectrum, second content, second height and second type of the second biological fluidized bed. The second spectrum represents the temperature spectrum of the second biological fluidized bed, the second content represents the dissolved oxygen content of the second biological fluidized bed, the second height represents the sediment height of the second biological fluidized bed, and the second type represents the bacterial community type of the second biological fluidized bed. Specifically, the second type differs from the first type (e.g., the first biological fluidized bed uses heterotrophic bacteria, while the second biological fluidized bed uses nitrifying or denitrifying bacteria). Therefore, the aeration mode of the second mode will be adjusted (e.g., nitrifying bacteria require precise low-to-medium power aeration, while denitrifying bacteria require low-oxygen or anoxic aeration). Based on the second spectrum (temperature of the second biological fluidized bed), the second content (dissolved oxygen content of the second biological fluidized bed), and the second height (sediment height of the second biological fluidized bed), the heating power, aeration power (i.e., air intake power), and aeration direction (air intake direction) of the second mode are adjusted to ensure a stable living environment for the microbial community in the second biological fluidized bed.

[0039] S340. After controlling the air intake unit to aerate the second biological fluidized bed in the second mode, the first fluidized water is subjected to a second fluidization treatment through the second biological fluidized bed to obtain the second treated water.

[0040] Specifically, the air intake unit switches to the second mode to aerate the second biological fluidized bed. After the first fluidized water enters the second biological fluidized bed, the bacteria in the second biological fluidized bed, in a suitable aeration environment, specifically degrade residual pollutants (such as ammonia nitrogen and small molecule organic matter that were not decomposed in the first biological fluidized bed), completing deep purification. Finally, the water that has undergone two stages of treatment is the second-treated water.

[0041] In some optional embodiments, controlling the first mode of the air intake unit according to the first pattern, first content, first height, and first type of the first biological fluidized bed includes: S311. Determine the first air intake direction and the first air intake power of the air intake unit according to the first type and the first preset table, wherein the first preset table is used to indicate the correspondence between the bacterial species and the air intake direction and the air intake power. Specifically, the first preset table is a pre-prepared "microbial community-air intake parameter comparison table," which clarifies the most suitable air intake direction (e.g., bottom air supply, side air supply, and full-area air supply) and air intake power (corresponding to the oxygen supply and fluidization intensity required by the microbial community). Therefore, by determining the first type of microorganism in the first biological fluidized bed (i.e., the dominant microbial community, such as aerobic heterotrophic bacteria, nitrifying bacteria, and denitrifying bacteria), and then referring to the first preset table, the corresponding first air intake direction and first air intake power can be directly matched.

[0042] S312. Determine the first heating power of the air intake unit based on the first spectrum and the first preset temperature. The first heating power represents the power of heating the air flowing to the first biological fluidized bed. Specifically, the first graph is the temperature distribution map of the first biological fluidized bed (showing both overall and local temperatures), the first preset temperature is the suitable growth temperature for the microbial community on the first biological fluidized bed (e.g., 20-30℃), and the first heating power is used to regulate the temperature of the incoming air to prevent cold air from affecting the activity of the microbial community.

[0043] If the temperature graph shows that the overall temperature is lower than the preset lower limit: set the positive heating power to heat the incoming air into hot air and blow it into the first biological fluidized bed to raise the water temperature and avoid low temperature inhibiting bacterial metabolism; the lower the temperature, the greater the heating power (but not exceeding the safety limit to prevent overheating).

[0044] If the temperature graph shows that the overall temperature is within the preset range: set the heating power to 0, no additional heating is needed, just maintain normal temperature air supply.

[0045] If the temperature graph shows that the overall temperature is greater than the preset upper limit, the heating power is set to 0 directly, and heat dissipation is adjusted by air intake to avoid the high temperature causing a decrease in bacterial activity.

[0046] S313. After correcting the first intake direction and the first intake power according to the first map, the second intake direction and the second intake power are obtained. Specifically, if there are local high-temperature areas in the temperature spectrum (e.g., a certain area > 35℃): if the original first air intake direction does not cover this high-temperature area, adjust the air intake direction to tilt towards the high-temperature area (to obtain the second air intake direction), and at the same time increase the first air intake power (to obtain the second air intake power). By enhancing the airflow circulation here, excess heat can be quickly dissipated, preventing the bacterial community from being damaged by high temperature and low oxygen.

[0047] If the temperature graph has local low temperature areas (e.g., a certain area <15℃): adjust the air intake direction to avoid this low temperature area (reduce direct airflow), and at the same time reduce the air intake power of the corresponding area (to obtain the second air intake power) to prevent excessive airflow from further lowering the water temperature, and maintain temperature stability in conjunction with the first heating power.

[0048] If the temperature difference across the entire area is large (e.g., the difference between different areas is >5℃): change the air intake direction to uniform air supply across the entire area, and then adjust the power (slightly higher power in high-temperature areas and slightly lower power in low-temperature areas) so that the airflow can mix with the water and reduce the temperature difference.

[0049] S314. After correcting the second intake direction and the second intake power according to the first content and the first height, a first target intake direction and a first target intake power are obtained. The first mode represents the first target intake direction, the first target intake power and the first heating power.

[0050] Specifically, by combining the first content (dissolved oxygen content) and the first height (sediment height, whether the carrier is piled up), the corrected second air intake direction and second air intake power are adjusted and optimized to ensure that both oxygen supply and the living space of the microbial community are guaranteed.

[0051] In some optional embodiments, determining the first heating power of the intake unit based on the first spectrum and the first preset temperature includes: S3121. When the first fluidization temperature at each point of the first biological fluidized bed is lower than the first preset temperature as indicated by the first spectrum, the temperature difference between the first fluidization temperature and the first preset temperature is configured as the temperature difference to be heated. Specifically, if the first fluidization temperature (actual temperature of the liquid in the first biological fluidized bed) of all regions in the first spectrum is lower than the first preset temperature (the temperature suitable for bacterial growth), then the temperature difference of each region is calculated based on the first preset temperature and the first fluidization temperature, and then the overall temperature difference to be heated is obtained, which is the temperature gap that needs to be made up by heating and air supply.

[0052] S3122. Obtain the first parameters of the first biological fluidized bed, the first parameters including the liquid density, specific heat capacity, thermal conductivity and volume of the first biological fluidized bed; Specifically, the first parameter includes the density (mass of liquid per unit volume), specific heat capacity (heat required to raise the temperature of the liquid by 1°C), thermal conductivity (the liquid's ability to transfer heat), and total liquid volume of the liquid within the first biological fluidized bed. Therefore, the amount of heat required to heat the liquid can be calculated based on the first parameter.

[0053] S3123. Determine the first heat amount by the temperature difference to be heated and the first parameter. The first heat amount represents the heat required to heat the liquid in the first biological fluidized bed to the first preset temperature. Specifically, the first heat is calculated using the temperature difference to be heated and the first parameter through a thermal formula: First heat = Liquid mass (density × volume) × Specific heat capacity × Temperature difference to be heated, and then adjusted for thermal conductivity (for example, liquids with low thermal conductivity require more heat). The first heat is the total heat theoretically required to heat all the liquids in the first biological fluidized bed from the current temperature to the first preset temperature.

[0054] S3124. Obtain environmental parameters, including temperature, humidity, wind speed and air parameters outside the first biological fluidized bed, wherein the air parameters characterize the composition of the air that exchanges heat with the first biological fluidized bed. Specifically, environmental parameters include the temperature, humidity, and wind speed outside the first fluidized bed (the higher the wind speed, the easier it is for heat to dissipate), as well as the composition of the air that exchanges heat with the first fluidized bed (such as the moisture and carbon dioxide content in the air, which will affect the heat exchange efficiency). These environmental parameters determine how much heat will be lost to the outside through the bed during the heating process.

[0055] S3125. Obtain the thermal conductivity coefficient between the liquid inside the first biological fluidized bed and the first biological fluidized bed; S3126. Determine the heat loss coefficient based on the thermal conductivity coefficient and the environmental parameters; Specifically, first, the thermal conductivity coefficient between the liquid inside the first biological fluidized bed and the bed body (such as the equipment wall) is obtained (reflecting the rate at which heat is transferred from the liquid to the bed body). Then, the heat loss coefficient is calculated comprehensively in conjunction with environmental parameters. The heat loss coefficient is a proportional value, representing what proportion of heat is lost to the outside during the heating process (for example, a lower ambient temperature and higher wind speed result in a higher loss coefficient and more heat loss). The calculation formula is as follows:

[0056]

[0057] in, This represents the thermal conductivity coefficient between the liquid inside the first biological fluidized bed and the bed body; This represents the contact area between the liquid inside the first biological fluidized bed and the bed wall; Indicates the convective heat transfer coefficient of the environment; This represents the heat exchange area between the outer wall of the first biological fluidized bed and the environment. Indicates ambient air density; Indicates the specific heat capacity of ambient air; Indicates ambient wind speed; This represents the effective contact area between the first biological fluidized bed and the flowing air. Indicates the environmental correction factor; Indicates ambient temperature; Indicates the relative humidity of the environment; Indicates parameters related to the composition of air; This indicates the actual temperature of the liquid inside the first biological fluidized bed.

[0058] S3127. Obtain a preset ventilation time, wherein the preset ventilation time represents the time for ventilation of the first biological fluidized bed; Specifically, the preset ventilation time is the duration of aeration and ventilation of the first biological fluidized bed (e.g., 2 hours). The calculation of heating power needs to be combined with the preset ventilation time. For the same amount of heat, the shorter the ventilation time, the greater the heating power required.

[0059] S3128. Determine the first heating power based on the preset ventilation time, the first heat, and the heat loss coefficient.

[0060] Specifically, the actual total heat required is obtained by adding the lost heat (first heat × heat loss coefficient) to the first heat (theoretically required heat); then, the first heating power is calculated by dividing the actual total heat by the preset ventilation time. The first heating power can heat the incoming air to the corresponding temperature, and after being blown into the first biological fluidized bed, it heats the liquid in the first biological fluidized bed to the first preset temperature within a preset time, while offsetting the heat loss and ensuring that the bacterial community is in a suitable temperature environment.

[0061] In some optional embodiments, where the first map characterizes different regions of the first biological fluidized bed with temperature differences, the method further includes: S3129. When the regional temperature difference is greater than the temperature difference threshold, obtain a temperature difference thermogram of the regional temperature difference within a preset time period. Specifically, the temperature difference values ​​of all regions in the first map (such as the difference between the highest temperature region and the lowest temperature region) are compared with the preset temperature difference threshold. If there is a region with a temperature difference greater than the temperature difference threshold, continuous temperature data within a preset time period (such as 30 minutes) is collected to generate a temperature difference heat map. The size of the temperature difference is marked in the chart with different shades of color, and the range of the target area is marked with boundary lines.

[0062] S3130. When the temperature difference thermogram indicates that the temperature difference in the region increases or remains unchanged, and the target area corresponding to the temperature difference in the region increases or remains unchanged, the first heating power is configured to zero. Specifically, if the regional temperature difference increases or remains unchanged, and the target area increases or remains unchanged, it indicates that the temperature distribution within the first biological fluidized bed is becoming increasingly uneven. If heating continues at this point, the high-temperature zone may become even hotter, while the low-temperature zone will struggle to heat up, further exacerbating the temperature difference. Therefore, the first heating power is configured to zero, heating is paused, and the water is mixed by adjusting the air intake direction (e.g., directing airflow to the low-temperature zone) and optimizing the air intake power (enhancing airflow mixing) to first balance the regional temperature difference. Heating is then resumed once the temperature difference has decreased.

[0063] S3131. When the temperature difference thermogram indicates that the temperature difference in the region decreases over time, or the target region decreases or changes, the first heating power is obtained by configuring the power curve of heating power changing over time based on the temperature difference thermogram and the first fluidization temperature. Specifically, if the temperature difference decreases over time, or the target area decreases or changes, it indicates that the temperature within the first biological fluidized bed is becoming more uniform. At this point, heating can be used to accelerate the overall temperature rise without exacerbating the temperature difference. Configure the power change curve: Based on the temperature recovery rate of each region in the temperature difference thermogram and the shrinking pace of the target area, set the heating power's variation over time. For example, use low power initially (to avoid excessively rapid temperature rise), gradually increasing the power as the temperature difference decreases, ultimately raising the temperature of all regions to the first preset temperature within a preset time. The average power (or real-time power set) corresponding to the dynamically changing power curve is the first heating power.

[0064] S3132. When the temperature difference in the region is less than or equal to the temperature difference threshold, obtain the power change value corresponding to a unit temperature difference in the region. Specifically, the power change value corresponding to a unit temperature difference determined by experimental data or empirical databases represents the amount of additional heating power that needs to be adjusted for every 1°C temperature difference in the region.

[0065] S3133. Determine the first heating power based on the power change value and the regional temperature difference.

[0066] Specifically, the power change per unit temperature difference is multiplied by the actual regional temperature difference to obtain the additional power adjustment required; then, the base heating power when there is no regional temperature difference (i.e., the power calculated only based on the difference between the overall temperature and the preset temperature) is added to (or subtracted from, corrected according to the direction of the temperature difference) to finally obtain the first heating power.

[0067] In some optional embodiments, during the process of the air intake unit aerating the fluidized bed unit in the air intake mode, the method further includes: S350. Obtain the historical operating data and resistance variation coefficient of the intake unit. The historical operating data represents the historical operating time, historical operating frequency, and historical operating environment of the intake unit. The resistance variation coefficient represents the coefficient by which the resistance of the intake unit changes with voltage. Specifically, historical operating data includes the intake unit's historical operating time (cumulative operating hours), historical operating frequency (number of starts and stops), and historical operating environment (such as whether it has been operating in a high temperature / high humidity / dust environment for a long time). Historical operating data reflects the degree of damage to the intake unit; for example, the longer the operating time and the more frequent the starts and stops, the more serious the aging of the components.

[0068] The resistance variation coefficient is a parameter characterizing the performance of core components of the intake unit (such as the motor and heating wire), reflecting the law of resistance change with voltage. The resistance variation coefficient of normal new components is relatively stable. However, if they age (such as due to motor wear or heating wire oxidation), the resistance will change abnormally, and the resistance variation coefficient will deviate from the preset standard value.

[0069] S351. Determine the first aging coefficient of the intake unit based on the historical working duration, the historical working frequency, and the historical working environment. Specifically, the first aging coefficient is calculated using a preset algorithm (such as "working time weight × cumulative time + working number weight × start-stop number + environmental weight × number of days in harsh environment"). The larger the value of the first aging coefficient, the more serious the aging caused by long-term use and environmental impact (for example, a first aging coefficient of 0.2 represents 20% aging).

[0070] S352. Determine the second aging coefficient of the intake unit based on the resistance change coefficient and the preset change coefficient; Specifically, by comparing the current resistance change coefficient with the preset change coefficient (the standard resistance change coefficient of the new component), the deviation ratio between the two is calculated, which is the second aging coefficient; the larger the deviation, the more severe the performance degradation of the core component and the higher the degree of aging.

[0071] S353. Determine the current aging coefficient of the intake unit based on the first aging coefficient and the second aging coefficient; Specifically, the current aging coefficient is obtained by weighting the two factors according to preset weights (e.g., the first aging coefficient accounts for 40% and the second aging coefficient accounts for 60%, which can be adjusted according to the actual situation), and comprehensively reflecting the overall aging status of the intake unit.

[0072] S354. Determine the maximum intake power of the intake unit based on the current aging system; Specifically, the maximum intake power of the intake unit will decrease with aging (for example, the output power of the motor will decrease under the same voltage after aging), and needs to be corrected according to the current aging coefficient: maximum intake power = rated maximum intake power of intake unit × (1 - current aging coefficient). The specific calculation method is not limited here.

[0073] S355. Determine the target number of bacteria to be added by the bacteria addition device based on the maximum intake power and the target intake power corresponding to the intake mode. Specifically, the bacterial count needs to be matched with the intake power (oxygen supply capacity, fluidization intensity): a decrease in intake power will lead to a reduction in oxygen supply and a weakening of fluidization effect. If the bacterial count is too high, a situation of "hypoxia + nutrient deficiency" will occur, resulting in a decrease in bacterial activity; if the count is too low, it will affect the treatment efficiency. Therefore, by comparing the maximum intake power with the target intake power (the target intake power is the ideal power set in the intake mode), if the maximum intake power is less than the target intake power, it indicates that the actual oxygen supply / fluidization capacity is insufficient. Based on the power difference between the two, the initial bacterial count addition amount (the initial amount is set based on the target intake power) is adjusted according to the principle of "power reduction ratio = bacterial count adjustment ratio". Example: The initial bacterial count is 100 units, the target intake power is 800W, the maximum intake power is 720W, and the power decrease percentage is (800-720) / 800=10%. Therefore, the target bacterial count is 100 units × (1+10%) = 110 units. By increasing the bacterial count by 10%, the treatment capacity for organic pollutants is improved. If the maximum intake power decreases beyond a threshold, the intake unit is replaced. For example, if the maximum intake power decreases by 30%, a new intake unit is replaced to prevent adding too many bacteria from disrupting the overall stability of the bacterial community.

[0074] S356. Control the air intake unit to aerate the fluidized bed unit at the maximum air intake power, and control the microbial addition device to add the target number of microorganisms to the fluidized bed unit.

[0075] Specifically, the air intake unit is controlled to aerate at the calculated maximum air intake power; it outputs maximum capacity based on its own aging state to avoid overload damage. The microbial addition device is controlled to add the target number of microorganisms to the fluidized bed unit, ensuring that the number of microorganisms matches the actual fluidization capacity, maintaining microbial stability and treatment effect.

[0076] In some optional embodiments, controlling the second mode of the air intake unit according to the second pattern, second content, second height, and second type of the second biological fluidized bed includes: S331. Determine the third intake direction and third intake power of the intake unit according to the second type and the first preset table; Specifically, the first preset table is a general "microbial community-air intake parameter comparison table". By determining the second type of the second biological fluidized bed, the first preset table is consulted to match the corresponding third air intake direction and third air intake power.

[0077] S332. Determine the second heating power of the air intake unit based on the second spectrum and the second preset temperature. The second heating power represents the power of heating the air flowing to the second biological fluidized bed. Specifically, the second graph is a temperature distribution map of the second biological fluidized bed (reflecting the real-time temperature of each region). The second preset temperature is the suitable growth temperature for the second type of bacterial community (different from the first preset temperature; for example, denitrifying bacteria are suitable for 15-25℃, and nitrifying bacteria are suitable for 20-30℃). The second heating power is used to regulate the air temperature introduced into the second bed to ensure a stable temperature environment for the bacterial community. Similar to the adjustment of the first heating power of the first biological fluidized bed, the adjustment of the second heating power is as follows: If the second graph shows that the second fluidization temperature (actual temperature of the liquid inside the bed) at all points in the second biological fluidized bed is lower than the second preset lower limit: set the positive heating power, heat the incoming air, and raise the water temperature inside the bed through the hot air. The lower the temperature, the greater the heating power.

[0078] If the second fluidization temperature is within the second preset temperature range: the heating power is set to 0, and no additional heating is required; If the second fluidization temperature is greater than the second preset temperature upper limit: set the heating power to 0 and adjust the ventilation to dissipate heat.

[0079] S333. After correcting the third intake direction and the third intake power according to the second diagram, the fourth intake direction and the fourth intake power are obtained. Specifically, based on the temperature details (local high / low temperature zones, temperature difference) of the second spectrum, the third air intake direction and power were optimized to obtain the fourth air intake direction and power, making the temperature of the second biological fluidized bed more suitable for the needs of the second type of bacterial community. The specific optimization method is the same as the optimization method of the first biological fluidized bed mentioned above, and will not be repeated here.

[0080] S334. After correcting the fourth intake direction and the fourth intake power according to the second content and the second height, a second target intake direction and a second target intake power are obtained. The second mode represents the second target intake direction, the second target intake power and the second heating power.

[0081] Specifically, if the dissolved oxygen is less than the suitable lower limit for the second type of bacteria: keep the fourth air intake direction unchanged and appropriately increase the fourth air intake power (to obtain the second target air intake power); if the low oxygen area is concentrated, further orient the fourth air intake direction to that area (to obtain the second target air intake direction) for precise oxygen supplementation.

[0082] If dissolved oxygen is greater than the appropriate upper limit: reduce the fourth air intake power (to obtain the second target air intake power) to avoid over-oxygenation inhibiting the bacterial community; at the same time, change the fourth air intake direction to dispersed air supply (to obtain the second target air intake direction) to avoid local oxygen enrichment.

[0083] If the sediment height exceeds the safety threshold: adjust the fourth air intake direction to tilt towards the bottom sediment concentration area (to obtain the second target air intake direction), and at the same time increase the fourth air intake power (to obtain the second target air intake power), use strong airflow to disperse the sediment, restore carrier fluidization, and avoid hypoxia and compression of the bottom microbial community.

[0084] If the sediment height is less than the safe value: maintain the fourth intake direction and power unchanged, or slightly reduce the power to avoid carrier loss.

[0085] In some optional embodiments, the step of obtaining the first target intake direction and the first target intake power after correcting the second intake direction and the second intake power based on the first content and the first height includes: S3141. When the first content is less than the preset dissolved oxygen content, the second intake power is increased according to the first difference between the preset dissolved oxygen content and the first content to obtain the first target intake power. Specifically, if the first concentration is less than the preset dissolved oxygen concentration, it indicates that aeration needs to be increased. The process involves calculating the first difference between the preset dissolved oxygen concentration and the first concentration; then, according to the preset rule of "a fixed power increment corresponding to each 1 mg / L difference in dissolved oxygen" (e.g., 1 mg / L difference corresponds to 200W of power), the required power increase is calculated; finally, the second intake power is added to the newly added power to obtain the first target intake power. By increasing the power, the oxygen supply is increased, quickly making up for the oxygen deficiency gap.

[0086] S3142. When the first content is greater than the preset dissolved oxygen content, the first target intake power is obtained by reducing the second intake power according to the second difference between the first content and the preset dissolved oxygen content. Specifically, if the first concentration is greater than the preset dissolved oxygen concentration, it indicates that aeration needs to be reduced. Calculate the second difference (first concentration minus preset dissolved oxygen concentration); then calculate the power difference that needs to be reduced according to the preset "fixed power reduction for every 1 mg / L dissolved oxygen difference"; finally, subtract the power difference from the second intake power to obtain the first target intake power. By reducing the power, the oxygen supply is reduced to avoid over-oxygenation inhibiting the bacterial community.

[0087] S3143. When the first content is equal to the preset dissolved oxygen content, the second intake power is configured as the first target intake power. Specifically, if the first content is equal to the preset dissolved oxygen content, then the current second intake power can just maintain a suitable oxygen supply, and no adjustment is needed. The second intake power can be directly used as the first target intake power.

[0088] S3144. When the first height is greater than the preset sediment height, the first target air intake direction is obtained by correcting the second air intake direction according to the third difference between the first height and the preset sediment height. Specifically, if the first height is greater than the preset sediment height, it indicates that there is too much sediment at the bottom, which will squeeze the living space of the microbial community and cause local hypoxia. It is necessary to adjust the air intake direction for dredging: First, calculate the third difference (first height minus preset sediment height); then correct it according to the rule that "the larger the difference, the more the air intake direction is biased towards the bottom accumulation area": ​​if the third difference is ≤2cm, adjust the second air intake direction to "bottom tilt 30° air supply"; if the third difference is >2cm, adjust it to "bottom tilt 60° and directional air supply to the accumulation area"; the final corrected direction is the first target air intake direction, which disperses the sediment and restores the fluidization of the carrier through directional strong airflow.

[0089] S3145. When the first height is less than or equal to the preset sediment height, the second air intake direction is configured as the first target air intake direction.

[0090] Specifically, if the first height is less than or equal to the preset sediment height, it means that the bottom sediment is within a safe range and will not affect the survival of the microbial community and the fluidization of the carrier. Therefore, there is no need to adjust the air intake direction, and the second air intake direction can be directly used as the first target air intake direction.

[0091] S400: The target treated water is obtained by processing the second treated water through the third processing module.

[0092] Specifically, refer to Figure 2 The third treatment module includes a phosphorus removal sedimentation tank, a breakpoint chlorination tank, and a clear water tank. The treated water first enters the phosphorus removal sedimentation tank, which removes residual phosphorus (inorganic and organic phosphorus that are difficult to completely degrade in biological fluidized beds) to prevent eutrophication (such as excessive algal growth) caused by subsequent discharge. Phosphorus removal agents are added through a dosing device: polyaluminum chloride, ferrous sulfate, lime, and other phosphorus removal agents are added to the phosphorus removal sedimentation tank. These agents will react chemically with phosphorus ions in the water to form water-insoluble precipitates (such as aluminum phosphate and ferric phosphate).

[0093] Flocculation and sedimentation separation: The agent and water are fully mixed by the stirring device in the phosphorus removal sedimentation tank to form flocs (containing phosphorus precipitates and a small amount of suspended impurities in the water); then the water flows into the settling area of ​​the sedimentation tank, and the flocs slowly sink to the bottom of the tank under the action of gravity to form phosphorus-containing sludge.

[0094] Sludge discharge and supernatant transport: The phosphorus-containing sludge at the bottom of the tank is periodically discharged to the sludge thickening tank through the sludge discharge pipe for subsequent sludge treatment. The supernatant (clearer water with phosphorus content meeting the standard) after removing phosphorus and suspended impurities enters the breakpoint chlorination tank.

[0095] Water that has undergone phosphorus removal and precipitation may still contain small amounts of ammonia nitrogen (due to incomplete degradation by the biological fluidized bed) and microorganisms such as bacteria and viruses. The breakpoint chlorination tank ensures that the water quality meets safety standards through sterilization and denitrification. An appropriate amount of chlorine gas (or chlorine-containing disinfectants such as sodium hypochlorite) is added to the breakpoint chlorination tank. The disinfectant reacts in the water to generate hypochlorous acid, a highly oxidizing agent. Hypochlorous acid can destroy the cell walls and nucleic acids of bacteria and viruses, completely killing harmful microorganisms in the water and preventing the spread of diseases through water. When the disinfectant dosage reaches the "breakpoint" (the minimum dose at which ammonia nitrogen in the water is completely oxidized), the ammonia nitrogen is oxidized and decomposed into nitrogen gas. Nitrogen gas is insoluble in water and will naturally escape, thus completely removing residual ammonia nitrogen (preventing ammonia nitrogen from causing odors and affecting water quality). By monitoring the pH value (suitable range 6.0-7.5) and residual chlorine content in the tank, the disinfectant dosage is precisely controlled; this ensures both sterilization and denitrification effects while avoiding excessive disinfectant that could lead to excessive residual chlorine in the water (producing odors or harmful byproducts). The treated water then enters the clear water tank.

[0096] The clear water tank serves as a storage facility, storing deeply treated water and balancing water volume fluctuations throughout the entire water treatment system. During the water's residence in the clear water tank, any remaining trace amounts of disinfectant continue to work, ensuring sustained sterilization. Simultaneously, any trace amounts of flocculent matter that may remain in the water will further settle, resulting in more stable and clearer water quality. Once the water in the clear water tank meets standards through online water quality monitoring (such as monitoring pH, residual chlorine, phosphorus content, and total bacterial count), it is transported through effluent pipes to the target location, either directly discharged into natural water bodies (such as rivers and lakes) or reused as reclaimed water (such as for industrial cooling, greening irrigation, and municipal miscellaneous uses). This water at this point is the final target treated water.

[0097] The beneficial effects of this invention include: obtaining first treated water by pretreating the wastewater to be treated through the first treatment module; acquiring the fluidization parameters of the fluidized bed unit, which indicate the temperature spectrum, dissolved oxygen content, sediment height, and bacterial species of the fluidized bed unit; controlling the air intake mode of the air intake unit according to the fluidization parameters, so that the fluidized bed unit fluidizes the first treated water to obtain second treated water, where the temperature spectrum, dissolved oxygen content, and sediment height of the fluidized bed unit correspond to the bacterial species; and obtaining the target treated water by treating the second treated water through the third treatment module. By precisely controlling the air intake mode of the air intake unit through the fluidization parameters of the fluidized bed unit, the dissolved oxygen content, temperature spectrum, and sediment height of the fluidized bed unit are adapted to the bacterial species, maintaining stable dissolved oxygen content, reducing carrier sedimentation and accumulation, thereby maintaining the stability of the bacterial community and ensuring the degradation efficiency of organic pollutants by the bacterial community.
