Description

Technical Field

[0001] This invention relates to the field of intelligent monitoring in aquaculture, and more particularly to a water treatment system and method for bullfrog farming. Background Technology

[0002] Bullfrog farming is an intensive aquaculture industry, and water quality is a crucial factor affecting bullfrog growth. Bullfrogs spend most of their time in water; feed is placed in the water by farmers, and the bullfrogs excrete directly in the water after eating. Skin debris from molting also remains in the water. This results in the water being rich in uneaten feed, excrement, and skin debris. The accumulation and decomposition of these substances in the water leads to high ammonia nitrogen levels and the proliferation of bacteria and viruses, making bullfrogs susceptible to bacterial infections and diseases. Current bullfrog farming practices include regular water changes and disinfection. However, existing water change methods rely on automatic water circulation systems within the ponds, continuously replacing water. This system cannot prioritize replacing water in heavily polluted areas, allowing pollutants to continue spreading within the pond and reducing the reliability of the water circulation and purification process. Summary of the Invention

[0003] The purpose of this invention is to provide a water treatment system and method for bullfrog farming. Based on the characteristics of foreign matter and water flow in the bullfrog farming pond, the system estimates the trend of water pollution changes in the pond and locates areas with severe pollutant accumulation, facilitating subsequent priority water circulation and replacement in these areas. Based on the trend of water pollution changes and the characteristics of bullfrog activity range changes in the pond, the system adjusts the water circulation and replacement process, while collecting the wastewater discharged from the water circulation and adjusting the primary purification treatment of the wastewater to ensure efficient pollutant discharge and rapid reduction of pollutant content in the wastewater. Based on the foreign matter content of the wastewater after primary purification, the system performs deep purification treatment on the wastewater, and based on the purified water output from the deep purification treatment, the system adjusts the water supply for water circulation and replacement, further optimizing the wastewater quality and returning it to the farming pond, thereby improving the reliability of water circulation and purification and inhibiting the spread of pollution within the pond.

[0067] Please see Figure 1 As shown in the figure, an embodiment of this application provides a water treatment system for bullfrog farming. The water treatment system for bullfrog farming includes:

[0068] The foreign object identification module is used to identify foreign objects in bullfrog breeding ponds and obtain the state characteristics of foreign objects in the breeding ponds.

[0069] The water pollution change trend estimation module is used to estimate the water pollution change trend in the aquaculture pond based on the characteristics of foreign matter state and the characteristics of water flow state in the aquaculture pond;

[0070] The water circulation replacement and adjustment module is used to adjust the water circulation in the breeding pond based on the trend of water pollution changes and the characteristics of changes in the activity range of bullfrogs in the breeding pond.

[0071] The primary purification module is used to collect the wastewater discharged from the water circulation and replacement in the aquaculture pond and to adjust the primary purification treatment of the wastewater.

[0072] The deep purification module is used to perform deep purification treatment on the effluent based on the foreign matter content of the effluent after primary purification treatment.

[0073] The water circulation supply adjustment module is used to adjust the water circulation supply based on the purified water output of the deep purification treatment.

[0074] The beneficial effects of the above embodiments are as follows: the water treatment system for bullfrog farming estimates the trend of water pollution changes in the farming pond based on the characteristics of foreign matter and water flow in the pond, locates areas with severe pollutant accumulation, and facilitates priority water circulation and replacement in the corresponding areas. Based on the trend of water pollution changes and the characteristics of bullfrog activity range changes in the farming pond, the system adjusts the water circulation and replacement in the farming pond, while collecting the wastewater discharged from the water circulation and replacing and adjusting the primary purification treatment of the wastewater to ensure the efficiency of pollutant discharge from the farming pond and quickly reduce the pollutant content of the wastewater. Based on the foreign matter content of the wastewater after primary purification, the system performs deep purification treatment on the wastewater, and based on the purified water output of the deep purification treatment, the system adjusts the water circulation supply for water circulation and replacement, further optimizing the wastewater quality and returning it to the farming pond, improving the reliability of water circulation and purification and inhibiting the spread of pollution in the pond.

[0075] In another embodiment, the foreign object identification module is used to identify the bullfrog breeding pond and obtain the state characteristics of foreign objects in the breeding pond, including:

[0076] All bullfrogs in the bullfrog breeding pond were tracked and identified to obtain their skin molting and excretion states during their activities. Based on the activity paths of all bullfrogs in the breeding pond, the skin molting and excretion states were spatially identified to obtain the foreign matter state characteristics in the breeding pond. Among them, the foreign matter state characteristics include the spatial distribution characteristics of foreign matter concentration in the breeding pond.

[0077] The water pollution trend estimation module is used to estimate the water pollution trend in aquaculture ponds based on the characteristics of foreign matter states and the characteristics of water flow states within the ponds. This includes:

[0078] Based on the characteristics of foreign matter states and the spatial distribution characteristics of water flow direction and velocity in the aquaculture pond, the movement and diffusion path of foreign matter in the aquaculture pond is predicted; based on the movement and diffusion path of foreign matter, the trend of water pollution change in the aquaculture pond is estimated; among which, the trend of water pollution change includes the trend of change of the water body area in the aquaculture pond where the concentration of foreign matter exceeds the preset concentration threshold.

[0079] The beneficial effects of the above embodiments are that the excrement and skin metabolites produced by bullfrogs during their breeding and growth process are the main sources of pollutants in the breeding pond. These pollutants may remain in the areas where bullfrogs move through the pond. By tracking the bullfrogs' activities in the pond, the spatial distribution of pollutants can be accurately determined. Specifically, visual tracking and identification are performed on all bullfrogs in the breeding pond to obtain the epidermal molting and excretion states of all bullfrogs during their activities, thus comprehensively and accurately determining the bullfrogs' living and metabolic behaviors. The epidermal molting state can be, but is not limited to, the amount of skin debris produced by the bullfrogs per unit time, and the excretion state can be, but is not limited to, the amount of excrement produced by the bullfrogs per unit time. Furthermore, based on the activity paths of all bullfrogs in the pond, the areas through which the bullfrogs move are located, and the epidermal molting and excretion states are spatially identified to obtain the spatial distribution characteristics of the concentration of skin debris and excrement in the pond, accurately determining the distribution of pollutants in the breeding pond. The water in the aquaculture pond is in a flowing state, causing pollutants to spread to other areas of the pond. This leads to the accumulation of pollutants in areas with initially low concentrations, thus affecting the overall water quality. Therefore, based on the characteristics of the foreign objects and the spatial distribution of water flow direction and velocity within the pond, the movement and diffusion paths of the foreign objects are predicted, accurately pinpointing the range of diffusion under the influence of water flow. Furthermore, based on these diffusion paths, the trend of changes in the area of ​​water where the concentration of foreign objects exceeds a preset concentration threshold is estimated, facilitating subsequent accurate assessment of whether the foreign objects in the pond affect the normal activities of the bullfrogs.

[0080] In another embodiment, the water circulation replacement and adjustment module is used to adjust the water circulation in the breeding pond based on the trend of water pollution changes and the characteristics of changes in the activity range of bullfrogs in the breeding pond, including:

[0081] Spatially compare the trend of water pollution change in the range of water bodies where the concentration of foreign matter in the aquaculture pond exceeds the preset concentration threshold with the change characteristics of the bullfrog activity range in the aquaculture pond to determine the water body area in the aquaculture pond where foreign matter affects bullfrogs; based on the location of the water body area in the aquaculture pond, adjust the water circulation replacement sequence of the water body area in the aquaculture pond.

[0082] The primary purification module is used to collect the effluent discharged from the aquaculture pond water circulation and to adjust the primary purification treatment of the effluent, including:

[0083] The wastewater from the water circulation and replacement process in the aquaculture pond is collected by sedimentation. Based on the average particle size of the sediment in the wastewater, the filtration flow rate for the primary purification treatment of the wastewater is adjusted.

[0084] The beneficial effect of the above embodiments is that when the concentration of foreign matter in a certain area of ​​the breeding pond is too high, the water quality in the corresponding area will suffer from problems such as hypoxia and turbidity, thereby affecting the activity level of bullfrogs in the corresponding area. By spatially comparing the trend of water pollution changes (including the range of water bodies in the breeding pond where the concentration of foreign matter exceeds a preset concentration threshold) with the characteristics of bullfrog activity range changes in the breeding pond, the water body area in the breeding pond where foreign matter affects bullfrogs is determined. The characteristics of bullfrog activity range changes in the breeding pond refer to the changes in the size of the bullfrog activity range over time. Specifically, by spatially comparing the trend of water pollution changes (including the range of water bodies in the breeding pond where the concentration of foreign matter exceeds a preset concentration threshold) with the characteristics of bullfrog activity range changes in the breeding pond, the overlapping area between the range of water bodies where the concentration of foreign matter exceeds the preset concentration threshold and the bullfrog activity range is defined as the water body area in the breeding pond where foreign matter affects bullfrogs. Based on the location of the water body within the aquaculture pond, the water circulation and replacement sequence for that area is adjusted. For example, wastewater extraction and purified water delivery are prioritized for that area to prevent pollutants accumulated there from spreading further to other areas of the pond. Additionally, the wastewater from the aquaculture pond's water circulation and replacement process is collected and settled. Based on the average particle size of the sediment, the filtration flow rate for the primary purification treatment is adjusted. For instance, the smaller the average particle size of the sediment, the lower the filtration flow rate for the primary purification treatment, thus effectively filtering and isolating the sediment.

[0085] In another embodiment, adjusting the filtration flow rate of the primary purification treatment of the effluent based on the average particle size of the sediment in the effluent includes:

[0086] Based on the volume of the vertical space between the corresponding water area of ​​the aquaculture pond and the bottom of the aquaculture pond;

[0087] A reference flow rate is set using the volume of the vertical space between the water body area and the bottom of the aquaculture pond;

[0088] The baseline flow rate is obtained using the following formula:

[0089]

[0090] Where Q0 represents the baseline flow rate; V represents the volume of the vertical space between the water area and the bottom of the aquaculture pond; and T represents the average residence time of the water in the aquaculture pond. This step determines a baseline flow rate value based on the spatial and flow time parameters of the aquaculture pond, providing a reference for subsequent adjustments.

[0091] The average particle size of the sediment in the effluent and the preset particle size reference value were extracted.

[0092] The baseline flow rate is adjusted using the average particle size of the sediment in the effluent and a preset particle size reference value to obtain the adjusted filtration flow rate for the primary purification treatment of the effluent.

[0093] The adjusted filtration flow rate for the primary purification treatment of the effluent is obtained using the following formula:

[0094]

[0095] Where Q represents the adjusted filtration flow rate of the primary purification treatment of the effluent; Q0 represents the baseline flow rate; d avg The average particle size of the sediment in the tailwater; d ref This represents the preset particle size reference value; 'a' represents the particle size response index, ranging from 0.4 to 0.7; 'k' represents the distribution correction coefficient, ranging from 0.1 to 0.3; and 'σ' represents the standard deviation of the particle size distribution. ref This represents the preset baseline distribution value, which ranges from 30μm to 50μm.

[0096] The beneficial effects of the above embodiments include the ability to adjust the flow rate by considering the average particle size and particle size distribution of the sediment, allowing the filtration process to precisely match the sedimentation characteristics of the effluent. When the average particle size is large or the particle size distribution varies greatly, reducing the flow rate allows the filtration system sufficient time to intercept the sediment, preventing large particles from penetrating the filter screen and improving the filtration effect. When the average particle size is small and the distribution is uniform, appropriately increasing the flow rate accelerates the treatment process and ensures purification efficiency. The characteristics of the effluent sediment change during aquaculture. This solution can monitor relevant parameters in real time and dynamically adjust the flow rate, always keeping the filtration system in optimal operating condition and continuously ensuring purification effect. Reasonable adjustment of the flow rate can avoid filter screen clogging and equipment wear caused by improper flow. Excessive flow can cause large particles to impact the filter screen, leading to clogging and wear, affecting equipment lifespan; insufficient flow results in low treatment efficiency. Precise adjustment of the flow rate can reduce such problems, extend equipment lifespan, and reduce maintenance costs. A flow rate adapted to the sediment characteristics makes the filtration equipment operate more stably, reduces system pressure fluctuations, ensures long-term stable operation of the equipment, and reduces the risk of production interruption due to equipment failure. This solution adjusts the flow rate as needed, avoiding the energy waste associated with traditional fixed flow rates. Reducing the flow rate when high flow is not required decreases power consumption, achieving energy conservation and aligning with sustainable development needs. Improved purification efficiency increases effluent reuse rates, reduces fresh water intake, achieves efficient water resource utilization, lowers aquaculture costs, and reduces the environmental pressure from wastewater discharge. Traditional filtration flow rate adjustment methods rely heavily on experience or fixed parameters, failing to fully consider the actual characteristics of sediments. This solution adjusts the flow rate using precise parameters such as average sediment particle size and standard deviation of particle size distribution, overcoming the inefficiency of traditional methods and significantly improving the precision of filtration. The characteristics of effluent constantly change during aquaculture, making timely responses difficult with traditional methods. This solution dynamically adjusts the flow rate based on real-time monitoring parameters, better adapting to various changes during the aquaculture process, maintaining excellent filtration performance and system performance, with significantly better adaptability than traditional methods. By improving purification efficiency, protecting equipment, and optimizing resource utilization, this solution offers greater overall benefits compared to traditional methods. It not only reduces equipment maintenance and operating costs but also improves water resource utilization, enhancing the sustainability and competitiveness of aquaculture production.

[0097] In another embodiment, the deep purification module is used to perform deep purification treatment on the effluent based on the foreign matter content of the effluent after primary purification treatment, including:

[0098] Based on the proportion of foreign matter in the effluent after primary purification, the duration of biodecomposition and the intensity of ultraviolet sterilization during the deep purification process of the effluent are adjusted.

[0099] The water circulation supply adjustment module is used to adjust the water circulation supply based on the purified water production rate of deep purification treatment, including:

[0100] Based on the purified water output per unit time of deep purification treatment and the volume of purified water required for water circulation replacement, the supply flow rate of purified water generated by deep purification treatment to the purified water input end of water circulation replacement is adjusted.

[0101] The beneficial effects of the above embodiments are that the effluent after primary purification still retains a certain amount of foreign matter. This foreign matter is composed of organic matter, which cannot be completely removed by physical filtration alone. Simultaneously, the effluent also contains a large number of invisible bacteria, which are also present alongside the foreign matter. Therefore, based on the proportion of foreign matter in the effluent after primary purification, the duration of biodegradation and the intensity of ultraviolet sterilization during the deep purification process are adjusted. Generally, the higher the proportion of foreign matter, the longer the biodegradation duration and the greater the intensity of ultraviolet sterilization during the deep purification process, thus rapidly improving the purification efficiency of the effluent. Furthermore, based on the purified water output per unit time and the volume of purified water required for water circulation, the supply flow rate of the purified water generated by the deep purification process to the purified water input of the water circulation system is adjusted. For example, the higher the purified water output per unit time and the larger the volume of purified water required for water circulation, the more adaptable the supply flow rate of the purified water generated by the deep purification process can be to the purified water input of the water circulation system, thereby improving the recycling rate of the purified effluent.

[0108] All bullfrogs in the bullfrog breeding pond were tracked and identified to obtain their skin molting and excretion states during their activities. Based on the activity paths of all bullfrogs in the breeding pond, the skin molting and excretion states were spatially identified to obtain the foreign matter state characteristics in the breeding pond. Among them, the foreign matter state characteristics include the spatial distribution characteristics of foreign matter concentration in the breeding pond.

[0109] Based on the characteristics of foreign matter states and the spatial distribution characteristics of water flow direction and velocity in the aquaculture pond, the movement and diffusion path of foreign matter in the aquaculture pond is predicted; based on the movement and diffusion path of foreign matter, the trend of water pollution change in the aquaculture pond is estimated; among which, the trend of water pollution change includes the trend of change of the water body area in the aquaculture pond where the concentration of foreign matter exceeds the preset concentration threshold.

[0110] The beneficial effects of the above embodiments are that the excrement and skin metabolites produced by bullfrogs during their breeding and growth process are the main sources of pollutants in the breeding pond. These pollutants may remain in the areas where bullfrogs move through the pond. By tracking the bullfrogs' activities in the pond, the spatial distribution of pollutants can be accurately determined. Specifically, visual tracking and identification are performed on all bullfrogs in the breeding pond to obtain the epidermal molting and excretion states of all bullfrogs during their activities, thus comprehensively and accurately determining the bullfrogs' living and metabolic behaviors. The epidermal molting state can be, but is not limited to, the amount of skin debris produced by the bullfrogs per unit time, and the excretion state can be, but is not limited to, the amount of excrement produced by the bullfrogs per unit time. Furthermore, based on the activity paths of all bullfrogs in the pond, the areas through which the bullfrogs move are located, and the epidermal molting and excretion states are spatially identified to obtain the spatial distribution characteristics of the concentration of skin debris and excrement in the pond, accurately determining the distribution of pollutants in the breeding pond. The water in the aquaculture pond is in a flowing state, causing pollutants to spread to other areas of the pond. This leads to the accumulation of pollutants in areas with initially low concentrations, thus affecting the overall water quality. Therefore, based on the characteristics of the foreign objects and the spatial distribution of water flow direction and velocity within the pond, the movement and diffusion paths of the foreign objects are predicted, accurately pinpointing the range of diffusion under the influence of water flow. Furthermore, based on these diffusion paths, the trend of changes in the area of ​​water where the concentration of foreign objects exceeds a preset concentration threshold is estimated, facilitating subsequent accurate assessment of whether the foreign objects in the pond affect the normal activities of the bullfrogs.

[0111] In another embodiment, based on the changing trends of water pollution and the changing characteristics of the bullfrog activity range in the breeding pond, the water circulation in the breeding pond is adjusted; the effluent discharged from the water circulation in the breeding pond is collected, and the primary purification treatment of the effluent is adjusted, including:

[0112] Spatially compare the trend of water pollution change in the range of water bodies where the concentration of foreign matter in the aquaculture pond exceeds the preset concentration threshold with the change characteristics of the bullfrog activity range in the aquaculture pond to determine the water body area in the aquaculture pond where foreign matter affects bullfrogs; based on the location of the water body area in the aquaculture pond, adjust the water circulation replacement sequence of the water body area in the aquaculture pond.

[0113] The wastewater from the water circulation and replacement process in the aquaculture pond is collected by sedimentation. Based on the average particle size of the sediment in the wastewater, the filtration flow rate for the primary purification treatment of the wastewater is adjusted.

[0114] The beneficial effect of the above embodiments is that when the concentration of foreign matter in a certain area of ​​the breeding pond is too high, the water quality in the corresponding area will suffer from problems such as hypoxia and turbidity, thereby affecting the activity level of bullfrogs in the corresponding area. By spatially comparing the trend of water pollution changes (including the range of water bodies in the breeding pond where the concentration of foreign matter exceeds a preset concentration threshold) with the characteristics of bullfrog activity range changes in the breeding pond, the water body area in the breeding pond where foreign matter affects bullfrogs is determined. The characteristics of bullfrog activity range changes in the breeding pond refer to the changes in the size of the bullfrog activity range over time. Specifically, by spatially comparing the trend of water pollution changes (including the range of water bodies in the breeding pond where the concentration of foreign matter exceeds a preset concentration threshold) with the characteristics of bullfrog activity range changes in the breeding pond, the overlapping area between the range of water bodies where the concentration of foreign matter exceeds the preset concentration threshold and the bullfrog activity range is defined as the water body area in the breeding pond where foreign matter affects bullfrogs. Based on the location of the water body within the aquaculture pond, the water circulation and replacement sequence for that area is adjusted. For example, wastewater extraction and purified water delivery are prioritized for that area to prevent pollutants accumulated there from spreading further to other areas of the pond. Additionally, the wastewater from the aquaculture pond's water circulation and replacement process is collected and settled. Based on the average particle size of the sediment, the filtration flow rate for the primary purification treatment is adjusted. For instance, the smaller the average particle size of the sediment, the lower the filtration flow rate for the primary purification treatment, thus effectively filtering and isolating the sediment.

[0115] In another embodiment, adjusting the filtration flow rate of the primary purification treatment of the effluent based on the average particle size of the sediment in the effluent includes:

[0116] Based on the volume of the vertical space between the corresponding water area of ​​the aquaculture pond and the bottom of the aquaculture pond;

[0117] A reference flow rate is set using the volume of the vertical space between the water body area and the bottom of the aquaculture pond;

[0118] The baseline flow rate is obtained using the following formula:

[0119]

[0120] Where Q0 represents the baseline flow rate; V represents the volume of the vertical space between the water area and the bottom of the aquaculture pond; and T represents the average residence time of the water in the aquaculture pond. This step determines a baseline flow rate value based on the spatial and flow time parameters of the aquaculture pond, providing a reference for subsequent adjustments.

[0121] The average particle size of the sediment in the effluent and the preset particle size reference value were extracted.

[0122] The baseline flow rate is adjusted using the average particle size of the sediment in the effluent and a preset particle size reference value to obtain the adjusted filtration flow rate for the primary purification treatment of the effluent.

[0123] The adjusted filtration flow rate for the primary purification treatment of the effluent is obtained using the following formula:

[0124]

[0125] Where Q represents the adjusted filtration flow rate of the primary purification treatment of the effluent; Q0 represents the baseline flow rate; d avg The average particle size of the sediment in the tailwater; d ref This represents the preset particle size reference value; 'a' represents the particle size response index, ranging from 0.4 to 0.7; 'k' represents the distribution correction coefficient, ranging from 0.1 to 0.3; and 'σ' represents the standard deviation of the particle size distribution. ref This represents the preset baseline distribution value, which ranges from 30μm to 50μm.

[0126] The beneficial effects of the above embodiments include the ability to adjust the flow rate by considering the average particle size and particle size distribution of the sediment, allowing the filtration process to precisely match the sedimentation characteristics of the effluent. When the average particle size is large or the particle size distribution varies greatly, reducing the flow rate allows the filtration system sufficient time to intercept the sediment, preventing large particles from penetrating the filter screen and improving the filtration effect. When the average particle size is small and the distribution is uniform, appropriately increasing the flow rate accelerates the treatment process and ensures purification efficiency. The characteristics of the effluent sediment change during aquaculture. This solution can monitor relevant parameters in real time and dynamically adjust the flow rate, always keeping the filtration system in optimal operating condition and continuously ensuring purification effect. Reasonable adjustment of the flow rate can avoid filter screen clogging and equipment wear caused by improper flow. Excessive flow can cause large particles to impact the filter screen, leading to clogging and wear, affecting equipment lifespan; insufficient flow results in low treatment efficiency. Precise adjustment of the flow rate can reduce such problems, extend equipment lifespan, and reduce maintenance costs. A flow rate adapted to the sediment characteristics makes the filtration equipment operate more stably, reduces system pressure fluctuations, ensures long-term stable operation of the equipment, and reduces the risk of production interruption due to equipment failure. This solution adjusts the flow rate as needed, avoiding the energy waste associated with traditional fixed flow rates. Reducing the flow rate when high flow is not required decreases power consumption, achieving energy conservation and aligning with sustainable development needs. Improved purification efficiency increases effluent reuse rates, reduces fresh water intake, achieves efficient water resource utilization, lowers aquaculture costs, and reduces the environmental pressure from wastewater discharge. Traditional filtration flow rate adjustment methods rely heavily on experience or fixed parameters, failing to fully consider the actual characteristics of sediments. This solution adjusts the flow rate using precise parameters such as average sediment particle size and standard deviation of particle size distribution, overcoming the inefficiency of traditional methods and significantly improving the precision of filtration. The characteristics of effluent constantly change during aquaculture, making timely responses difficult with traditional methods. This solution dynamically adjusts the flow rate based on real-time monitoring parameters, better adapting to various changes during the aquaculture process, maintaining excellent filtration performance and system performance, with significantly better adaptability than traditional methods. By improving purification efficiency, protecting equipment, and optimizing resource utilization, this solution offers greater overall benefits compared to traditional methods. It not only reduces equipment maintenance and operating costs but also improves water resource utilization, enhancing the sustainability and competitiveness of aquaculture production.

[0127] In another embodiment, based on the foreign matter content of the effluent after primary purification, the effluent undergoes further purification treatment; based on the purified water output from the further purification treatment, the water circulation supply is adjusted, including:

[0128] Based on the proportion of foreign matter in the effluent after primary purification, the duration of biodecomposition and the intensity of ultraviolet sterilization during the deep purification process of the effluent are adjusted.

[0129] Based on the purified water output per unit time of deep purification treatment and the volume of purified water required for water circulation replacement, the supply flow rate of purified water generated by deep purification treatment to the purified water input end of water circulation replacement is adjusted.

[0130] The beneficial effects of the above embodiments are that the effluent after primary purification still retains a certain amount of foreign matter. This foreign matter is composed of organic matter, which cannot be completely removed by physical filtration alone. Simultaneously, the effluent also contains a large number of invisible bacteria, which are also present alongside the foreign matter. Therefore, based on the proportion of foreign matter in the effluent after primary purification, the duration of biodegradation and the intensity of ultraviolet sterilization during the deep purification process are adjusted. Generally, the higher the proportion of foreign matter, the longer the biodegradation duration and the greater the intensity of ultraviolet sterilization during the deep purification process, thus rapidly improving the purification efficiency of the effluent. Furthermore, based on the purified water output per unit time and the volume of purified water required for water circulation, the supply flow rate of the purified water generated by the deep purification process to the purified water input of the water circulation system is adjusted. For example, the higher the purified water output per unit time and the larger the volume of purified water required for water circulation, the more adaptable the supply flow rate of the purified water generated by the deep purification process can be to the purified water input of the water circulation system, thereby improving the recycling rate of the purified effluent.

[0131] In summary, this water treatment system and method for bullfrog farming estimates the water pollution trends in the farming ponds based on the characteristics of foreign matter and water flow within the ponds. It identifies areas with severe pollutant accumulation, facilitating prioritized water circulation and replacement in these areas. Based on these trends and the changing activity range of the bullfrogs, the system adjusts the water circulation, collecting the wastewater and adjusting its primary purification process to ensure efficient pollutant removal and rapid reduction of pollutant content. Finally, based on the foreign matter content of the primary-purified wastewater, it performs advanced purification and adjusts the water supply based on the purified water output. This further optimizes the wastewater quality before returning it to the farming ponds, improving the reliability of water circulation and purification and inhibiting the spread of pollution within the ponds.
