[0020] With the rapid development of aquaculture, the environmental impact of aquaculture wastewater discharge has become increasingly prominent. Aquaculture wastewater contains large amounts of organic matter, nitrogen, phosphorus pollutants, and antibiotic residues. If discharged without effective treatment, it will pollute the receiving water body and affect the stability and safety of the regional aquatic ecosystem. However, current technologies typically treat aquaculture wastewater using a fixed operating mode, failing to fully consider the ecological and pollution characteristics of the wastewater. The entire purification process lacks specificity, and the initial data analysis phase fails to effectively analyze and utilize more key water quality data with synergistic effects, resulting in poor purification effects and energy waste.

[0021] In view of this, embodiments of this application provide a method, system, electronic equipment, and storage medium for controlling the purification of aquaculture wastewater. This solution monitors the water quality data of the wastewater generated by aquaculture ponds and then performs calculations. Subsequently, it analyzes the comprehensive index of relevant water quality indicators of the wastewater based on the water quality data and the calculated wastewater to adjust the operating status of the purification equipment. This allows for targeted and effective purification of aquaculture wastewater while accurately grasping its water quality status. By adjusting the operating time of the water pump, energy consumption can be reduced, and the treatment cost of aquaculture wastewater purification can be decreased, resulting in certain economic and environmental benefits.

The server can also be a node server in a blockchain network. The software can be an application implementing the above method, but is not limited to these forms.

[0023] Please see Figure 1 , Figure 1 This is an optional flowchart illustrating a method for purifying and controlling aquaculture wastewater provided in an embodiment of this application. The method may include, but is not limited to, the following steps S101 to S103: Step S101: Obtain water quality data of the wastewater generated by aquaculture ponds, including basic physicochemical data and key pollutant data of the wastewater. Step S102: Calculate the comprehensive index of water quality ecological indicators and the comprehensive index of water quality pollutant indicators of the effluent based on the basic physicochemical data and key pollutant data of the effluent. Step S103: When the basic physicochemical data and / or key pollutant data of the effluent do not meet the standard requirements, or when the basic physicochemical data and key pollutant data of the effluent both meet the standard requirements, but the comprehensive index of water quality ecological indicators and / or the comprehensive index of water quality pollutant indicators of the effluent do not meet the threshold requirements, adjust the operating status of the purification equipment and adjust the running time of the water pump; wherein, the water pump is used to transport the effluent to the purification equipment, and the purification equipment is used to purify the effluent.

[0024] Steps S101 to S103 of this application embodiment involve monitoring the water quality data of the wastewater generated by aquaculture ponds and then performing calculations. Subsequently, the operation status of the purification equipment is adjusted based on the comprehensive index of the wastewater's water quality data and the calculated wastewater's relevant water quality indicators. This can achieve energy-saving and efficient purification of aquaculture wastewater.

[0025] In step S101 of some embodiments, the basic physicochemical data of the effluent include dissolved oxygen concentration, pH value, turbidity, conductivity and temperature of the effluent, and the key pollutant data of the effluent include ammonia nitrogen concentration, nitrite concentration, nitrate concentration, total phosphorus concentration, chemical oxygen demand (COD) and total suspended solids (TSS) concentration of the effluent.

[0026] In this embodiment of the application, the water quality data of the tailwater can be collected by a water quality sensor installed at the outlet of the aquaculture pond. The water quality sensor includes a dissolved oxygen sensor, a pH sensor, a turbidity sensor, a conductivity sensor, a temperature sensor, an ammonia nitrogen sensor, a nitrite sensor, a nitrate sensor, a total phosphorus sensor, a COD sensor, and a suspended solids concentration sensor.

[0027] In step S102 of some embodiments, the comprehensive index of water quality ecological indicators of the effluent is mainly calculated based on the basic physicochemical data of the effluent. The corresponding implementation process may include, but is not limited to, the following steps S201 to S202: Step S201: Normalize the basic physicochemical data of the effluent. This can be understood as scaling each data point in the basic physicochemical data of the effluent to a preset range, preferably set as follows: .

[0028] Specifically, for each data point in the basic physicochemical data of the effluent, a first preset standard range corresponding to the data is obtained. The first preset standard range includes a first maximum standard limit and a first minimum standard limit. The data is subtracted from the first minimum standard limit to obtain a first difference. The first maximum standard limit is subtracted from the first minimum standard limit to obtain a second difference. The first difference is then divided by the second difference to obtain the normalized result of the data.

[0029] Step S202: Calculate the basic physicochemical data of the normalized effluent using the first expression to obtain the comprehensive index of the effluent's water quality ecological indicators; wherein, the first expression is: ; In the formula, It is a comprehensive index of water quality and ecological indicators. This represents the normalized dissolved oxygen concentration. for The corresponding weighting coefficients, The pH value is the normalized value. for The corresponding weighting coefficients, The turbidity is the normalized value. for The corresponding weighting coefficients, The normalized conductivity is for The corresponding weighting coefficients, The normalized temperature. for The corresponding weighting coefficients.

[0030] In the first expression, This is because the effects of electrical conductivity and temperature on aquatic organisms are not independent; there is a significant interaction between the two. For example, high electrical conductivity at high temperatures (such as in marine aquaculture) can exacerbate osmotic stress in fish, while low electrical conductivity at low temperatures (such as in freshwater) may lead to abnormal dissolved oxygen saturation. (Molecular part) The fundamental contributions of both are reflected through a weighted summation method, with the denominator being... It is a punishment for the inconsistency between the two.

[0031] In this embodiment of the application, the comprehensive index of water quality ecological indicators of the effluent is obtained by comprehensively calculating the various data contained in the basic physicochemical data of the effluent. This quantitative index can help assess the impact of the effluent on the ecological environment.

[0032] In step S102 of some embodiments, the main task is to calculate the comprehensive index of water quality pollutants in the effluent based on the key pollutant data of the effluent. The corresponding implementation process may include, but is not limited to, the following steps S301 to S302: Step S301: Normalize the key pollutant data of the effluent. This can be understood as scaling each data point in the key pollutant data of the effluent to a preset range, which is preferably set to... .

[0033] Specifically, for each data point contained in the key pollutant data of the effluent, a second preset standard range corresponding to the data is obtained. The second preset standard range includes a second maximum standard limit and a second minimum standard limit. The data is subtracted from the second minimum standard limit to obtain a third difference. The second maximum standard limit is subtracted from the second minimum standard limit to obtain a fourth difference. The third difference is then divided by the fourth difference to obtain the normalized result of the data.

[0034] Step S302: Calculate the key pollutant data of the normalized effluent using the second expression to obtain the comprehensive index of water quality pollutant indicators for the effluent; wherein, the second expression is: ; In the formula, It is a comprehensive index of water quality pollutants. This represents the normalized ammonia nitrogen concentration. for The corresponding weighting coefficients, This represents the normalized nitrite concentration. for The corresponding weighting coefficients, This represents the normalized nitrate concentration. for The corresponding weighting coefficients, This represents the normalized total phosphorus concentration. This is the normalized chemical oxygen demand. In order to be in and The corresponding weighting coefficients under synergistic influence The normalized total suspended solids concentration. for The corresponding weighting coefficients.

[0035] In the second expression, The setting is based on the synergistic effect of phosphorus and organic COD. Eutrophication requires the simultaneous presence of excess phosphorus (which promotes algal growth) and organic COD (which provides a carbon source). High phosphorus or high organic COD alone usually does not trigger severe algal blooms. It can quantify the degree of coexistence between phosphorus and organic matter COD, the denominator part It is a punishment for the inconsistency between the two.

[0036] In this embodiment of the application, the comprehensive index of water quality pollutants in the effluent is obtained by comprehensively calculating the various data contained in the key pollutant data of the effluent. This quantitative index can help assess the pollution level of the effluent itself.

[0037] In step S103 of some embodiments, if the basic physicochemical data and / or key pollutant data of the effluent do not meet the standard requirements, it can be understood as: the basic physicochemical data of the effluent does not meet the first preset condition and / or the key pollutant data of the effluent does not meet the second preset condition. The first preset condition is used to limit each data point in the basic physicochemical data of the effluent to fall within its corresponding first preset standard range. The first preset condition can be applied to the normalization processing operation in step S201 above. The second preset condition is used to limit each data point in the key pollutant data of the effluent to fall within its corresponding second preset standard range. The second preset condition can be applied to the normalization processing operation in step S301 above. It should be noted that when the basic physicochemical data and key pollutant data of the effluent both meet the standard requirements, that is, when the basic physicochemical data of the effluent meets the first preset condition and the key pollutant data of the effluent meets the second preset condition, it means that it is currently impossible to verify that the effluent definitely has compound pollution (i.e., toxic substances exceeding the standard) and / or ecological function imbalance. However, it cannot be ruled out that the effluent may have compound pollution risk and / or ecological function imbalance risk. At this time, further judgment needs to be made based on the comprehensive index of water quality ecological indicators and the comprehensive index of water quality pollutant indicators of the effluent.

[0038] In step S103 of some embodiments, if the comprehensive index of the water quality ecological indicators and / or the comprehensive index of the water quality pollutants in the effluent do not meet the threshold requirements, it can be understood as: the comprehensive index of the water quality ecological indicators in the effluent does not meet the third preset condition and / or the comprehensive index of the water quality pollutants in the effluent does not meet the fourth preset condition. The third preset condition is used to limit the comprehensive index of the water quality ecological indicators in the effluent to be less than the first preset index threshold, and the fourth preset condition is used to limit the comprehensive index of the water quality pollutants in the effluent to be less than the second preset index threshold.

[0039] In step S103 of some embodiments, the purification equipment is equipped with an ecological function restoration device and a toxic substance removal device. The ecological function restoration device is used to restore the physicochemical parameters of the effluent, and the toxic substance removal device is used to remove pollutants from the effluent.

[0040] Preferably, the ecological function restoration equipment may internally include an aerator, a pH controller, an integrated water purification system, and a reverse osmosis system. The aerator is used to increase the dissolved oxygen concentration of the effluent, the pH controller is used to adjust the pH value of the effluent, the integrated water purification system is used to reduce the turbidity of the effluent using physical filtration and sedimentation technology, and the reverse osmosis system is used to reduce the conductivity of the effluent. When wastewater enters the ecological function restoration equipment, it undergoes corresponding purification treatment sequentially through the various internal devices.

[0041] Preferably, the toxic substance removal equipment may internally include aeration equipment, physical sedimentation equipment, flotation equipment, and biodegradation equipment. The aeration equipment is used to remove nitrogen from the effluent using a biological denitrification process to reduce the ammonia nitrogen concentration. The physical sedimentation equipment is used to filter the effluent to remove silt, colloidal particles, and biological sludge. The flotation equipment is used to reduce the total suspended solids concentration of the effluent, and the biodegradation equipment is used to reduce the chemical oxygen demand (COD) of the effluent. When wastewater enters the toxic substance removal equipment, it undergoes corresponding purification treatment sequentially through the various internal devices.

[0042] In step S103 of some embodiments, regarding the step of adjusting the operating status of the purification equipment when the basic physicochemical data and / or key pollutant data of the effluent do not meet the standard requirements, the corresponding implementation methods may include the following three situations: In the first scenario, when only the basic physicochemical data of the effluent fails to meet the standard requirements, that is, when the basic physicochemical data of the effluent fails to meet the first preset condition, but the key pollutant data of the effluent meets the second preset condition, it indicates that the effluent only has an imbalance in ecological function. In this case, only the ecological function restoration equipment is activated, so that the effluent generated by the aquaculture pond is pumped to the purification equipment and directly purified by the ecological function restoration equipment inside.

[0043] In the second scenario, when only the key pollutant data of the effluent does not meet the standard requirements, that is, when the basic physicochemical data of the effluent meets the first preset condition, but the key pollutant data of the effluent does not meet the second preset condition, it indicates that the effluent only has a complex pollution situation. In this case, only the toxic substance removal equipment is activated, so that the effluent generated by the aquaculture pond is pumped to the purification equipment and directly purified by the toxic substance removal equipment installed inside.

[0044] In the third scenario, when the basic physicochemical data and key pollutant data of the effluent do not meet the standard requirements, that is, when the basic physicochemical data of the effluent do not meet the first preset condition and the key pollutant data of the effluent do not meet the second preset condition, it indicates that the effluent is simultaneously experiencing ecological function imbalance and compound pollution. In this case, ecological function restoration equipment and toxic substance removal equipment are activated, so that the effluent generated from aquaculture ponds is pumped to the purification equipment and then undergoes corresponding purification treatment through the ecological function restoration equipment and toxic substance removal equipment installed inside, or undergoes corresponding treatment through the toxic substance removal equipment and ecological function restoration equipment installed inside.

[0045] In step S103 of some embodiments, regarding the step of adjusting the operating status of the purification equipment when the basic physicochemical data and key pollutant data of the effluent meet the standard requirements, but the comprehensive index of the water quality ecological index and / or the comprehensive index of the water quality pollutant index of the effluent do not meet the threshold requirements, the corresponding implementation methods may include the following three situations: In the first scenario, when only the comprehensive index of the water quality ecological indicators of the effluent fails to meet the threshold requirement, that is, when the comprehensive index of the water quality ecological indicators of the effluent fails to meet the third preset condition, but the comprehensive index of the water quality pollutant indicators of the effluent meets the fourth preset condition, it indicates that the effluent only has the risk of ecological function imbalance. In this case, only the ecological function restoration equipment is activated, so that the effluent generated by the aquaculture pond is pumped to the purification equipment and directly purified by the ecological function restoration equipment inside.

[0046] In the second scenario, when only the comprehensive index of water pollutant indicators in the effluent does not meet the threshold requirement, that is, when the comprehensive index of water ecological indicators in the effluent meets the third preset condition but the comprehensive index of water pollutant indicators in the effluent does not meet the fourth preset condition, it indicates that the effluent only has a risk of compound pollution. In this case, only the toxic substance removal equipment is activated, so that the effluent generated from the aquaculture pond is pumped to the purification equipment and directly purified by the toxic substance removal equipment installed inside.

[0047] In the third scenario, when both the comprehensive index of the water quality ecological indicators and the comprehensive index of the water quality pollutants in the effluent fail to meet the threshold requirements—that is, when the comprehensive index of the water quality ecological indicators fails to meet the third preset condition and the comprehensive index of the water quality pollutants in the effluent fails to meet the fourth preset condition—it indicates that the effluent simultaneously carries the risk of ecological function imbalance and the risk of compound pollution. In this case, ecological function restoration equipment and toxic substance removal equipment are activated. The effluent from the aquaculture pond is pumped to the purification equipment and then sequentially undergoes purification treatment through the internal ecological function restoration equipment and toxic substance removal equipment, or vice versa.

[0048] Understandably, when both the comprehensive index of water quality ecological indicators and the comprehensive index of water quality pollutants in the effluent meet the threshold requirements, that is, when the comprehensive index of water quality ecological indicators in the effluent meets the third preset condition and the comprehensive index of water quality pollutants in the effluent meets the fourth preset condition, it indicates that there is no risk of ecological imbalance or compound pollution in the effluent. In this case, there is no need to use purification equipment to purify the effluent, and the water quality data of the effluent generated by the aquaculture pond can be obtained again for analysis.

[0049] In some embodiments, step S103, regarding adjusting the operating time of the water pump, may include, but is not limited to, the following steps S401 to S403: Step S401: Obtain the treatment efficiency of the purification equipment, and then calculate the minimum operating time of the water pump by combining the comprehensive index of the water quality ecological index and the comprehensive index of the water quality pollutant index of the effluent. Step S402: Obtain the volume of the tailwater and the operating parameters of the water pump, and then calculate the optimal operating time of the water pump by combining the comprehensive index of the water quality ecological index and the comprehensive index of the water quality pollutant index of the tailwater. Step S403: Determine the final required operating time of the water pump based on the minimum and optimal operating times of the water pump, so as to control the operation of the water pump.

[0050] In step S401 above, a first deviation between the comprehensive index of water quality ecological indicators of the effluent and a first preset index threshold is calculated, the first preset index threshold being recorded in the third preset condition above; and a second deviation between the comprehensive index of water quality pollutant indicators of the effluent and a second preset index threshold is calculated, the second preset index threshold being recorded in the fourth preset condition above. Then, based on the treatment efficiency of the purification equipment, the first deviation, and the second deviation, the minimum residence time required for the effluent in the purification equipment is calculated and defined as the minimum operating time of the water pump, which can be calculated using the following expression: ; In the formula, This is the minimum operating time of the water pump. This is a comprehensive index of water quality and ecological indicators for the tailwater. The first preset index threshold, The first deviation, for The corresponding weighting coefficients, The comprehensive index of water pollutant indicators in the effluent. The second preset index threshold, This is the second deviation. for The corresponding weighting coefficients, This refers to the processing efficiency of the purification equipment.

[0051] It should be noted that the total energy consumption model for effluent purification can be constructed in this application as follows: ; In the formula, The total energy consumption for effluent purification. For fixed energy consumption, For the power of the water pump, For the operating time of the water pump, Energy consumption generated by the operation of the water pump The energy consumption generated by the operation of the purification equipment, including the energy consumption generated by the operation of the water pump and the energy consumption generated by the operation of the purification equipment, are all variable energy consumption. As can be seen from the above total energy consumption model for effluent purification, in order to reduce the energy consumption of effluent treatment, in addition to considering the energy consumption generated by the operation of the water pump, the energy consumption generated by the operation of the purification equipment must also be considered. The shorter the residence time of the effluent in the purification equipment, the lower the energy consumption generated by the operation of the purification equipment. Therefore, this application proposes to calculate the shortest residence time of the effluent in the purification equipment in order to assist in adjusting the final required operating time of the water pump in the subsequent process.

[0052] Fixed energy consumption can be understood as the standby energy consumption of the relevant basic equipment used in the effluent purification process, such as the energy consumption generated by electronic devices used to realize data analysis and calculation functions during continuous operation, and the basic power supply energy consumption of water quality sensors. These energy consumptions will not change with the running time of the water pump and the amount of effluent treated, and will remain relatively stable within a certain period of time.

[0053] The energy consumption generated by the operation of the water pump is related to the pump's operating time and flow rate. The longer the pump's operating time and the larger the flow rate, the higher the energy consumption. Furthermore, the operation of the water pump also affects the energy consumption of other treatment stages, such as the residence time of effluent in the purification equipment, which in turn affects the metabolic efficiency of microorganisms in the biological treatment process and the reaction effect of chemical treatment agents, indirectly generating variable energy consumption.

[0054] In step S402 above, the operating parameters of the water pump include the pump's flow rate and efficiency. The optimal operating time of the water pump can be calculated using the following expression: ; In the formula, This is the optimal operating time for the water pump. The preset conversion factor is used. The comprehensive index of water pollutant indicators in the effluent. The volume of the tailwater. The efficiency of a water pump can be understood as its actual effectiveness, encompassing energy loss, pipe friction, etc., and its value typically falls within [a certain range]. Within the range, The flow rate of the water pump. This is a comprehensive index of water quality and ecological indicators for the tailwater. This is the day / night correction factor, which is preferably set at night. . Used to quantify the total pollution load of effluent. Used to characterize the system's purification capacity, among which Used to characterize the degree of water quality defects in tailwater.

[0055] In step S403 above, the step of determining the final required operating time of the water pump based on the minimum and optimal operating times can be implemented in the following two ways: In the first case, when the optimal operating time of the water pump is greater than or equal to the minimum operating time of the water pump, the final required operating time of the water pump is the optimal operating time of the water pump. In the second scenario, when the optimal operating time of the water pump is less than the minimum operating time, the final required operating time of the water pump is determined to be the minimum operating time of the water pump.

[0056] In this embodiment of the application, considering that with the volume of the tailwater remaining constant, the longer the pump runs and the lower the pump flow rate, the longer the tailwater purification process will be, the energy consumption can be effectively reduced by adaptively adjusting the final required running time of the pump using the comprehensive index of the tailwater's ecological water quality index and the comprehensive index of the water quality pollutants index.
