[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] At present, the technical complexity of this treatment system is high, involving multiple treatment stages and technical equipment, requiring operators to have a high level of professional knowledge and ability, which increases the difficulty of operation and labor costs. In order to solve this technical problem, a factory aquaculture tailwater treatment system is proposed. Please refer to Figure 1The system includes a water quality data acquisition unit, a tailwater treatment pool environment data acquisition unit, a tailwater treatment pool status acquisition unit, a water quality data analysis and processing unit, and a tailwater treatment pool control unit.

[0019] The water quality data collection unit is used to collect the pollutant concentration data at the inlet of the tailwater treatment pool and the pollutant concentration data at the outlet of the tailwater treatment pool. The pollutant concentration data at the inlet of the tailwater treatment pool is expressed as , ,..., , the pollutant concentration data at the outlet of the tailwater treatment tank is expressed as , ,..., , and the subscript represents the number of collected pollution concentration data at the inlet of the tailwater treatment pool, and the superscript Indicates the number of the corresponding tailwater treatment, and the number is unique.

[0020] The tailwater treatment pool environment data acquisition unit is used to collect the temperature data of the environment where the tailwater treatment pool is located. The temperature data of the environment where the tailwater treatment pool is located is expressed as , The tailwater treatment pool status collection unit is used to collect the treatment capacity of each tailwater treatment pool. The treatment capacity of the tailwater treatment pool is expressed as: , ,..., .

[0021] The water quality data collection unit, the tailwater treatment pool environment data layer collection unit and the tailwater treatment pool status collection unit send the collected data to the water quality data analysis and processing unit; The water quality data analysis and processing unit calculates the real-time pollution load of the sewage pool based on the collected pollutant concentration data at the inlet and outlet of the tailwater treatment pool. The calculation expression is as follows: In the formula, Indicates the pollutant concentration data and the current running tailwater pool entrance. It represents the sum of all pollution loads in the tailwater pool currently in operation, which is the real-time pollution load.

[0022] The water quality data analysis and processing unit calculates the microbial influence coefficient based on the temperature data of the environment in which the tailwater treatment pool is located. The calculation expression is as follows: In the formula, represents the microbial influence coefficient, represents the temperature coefficient, which is 1.07. represents the reaction rate constant of the pollutant at 20 degrees Celsius, It represents the difference between the current temperature and 20 degrees Celsius. The specific types of pollutants are the same as the main pollutants in the aquaculture tailwater. The main pollutants are different according to different aquaculture needs. It should be noted that the reaction rate constant is a known value. The corresponding reaction rate constant is selected according to the pollutants in the actual tailwater pool.

[0023] The water quality data analysis and processing unit calculates the total treatment capacity of tailwater treatment according to the treatment capacity of each tailwater treatment pool. The calculation expression is as follows: In the formula, Indicates the total treatment capacity of tailwater treatment, It represents the sum calculation of the treatment capacity of all tailwater treatment ponds.

[0024] The water quality data analysis and processing unit calculates the tailwater treatment efficiency data based on the pollutant concentration data at the inlet of the tailwater treatment pool and the pollutant concentration data at the outlet of the tailwater treatment pool. The calculation expression is as follows: In the formula, It represents the difference between the pollutant concentration at the inlet of all tailwater treatment pools and the pollutant concentration at the inlet of all tailwater treatment pools. Indicates the tailwater treatment efficiency data, Represents tailwater treatment efficiency data.

[0025] After the real-time pollution load, microbial impact coefficient and tailwater treatment efficiency data are calculated, the water quality data analysis and processing unit determines whether it is necessary to add or reduce tailwater treatment pools according to the number of tailwater treatment pools currently started, and generates an opening or closing signal accordingly. The specific standards for generating an opening or closing signal are as follows; when ,and When , a signal to start all tailwater treatment pools is generated; when ,and When , a signal for starting multiple tailwater treatment pools is generated; when ,and When , a signal for starting multiple tailwater treatment pools is generated; in Indicates the real-time pollution load upper limit of the tailwater treatment pool.

[0026] when ,and When the power is on, a signal to close part of the tailwater treatment pool is generated.

[0027] By comparing the real-time pollution load with the upper limit of the real-time pollution load of the tailwater treatment pool for sewage treatment, it is determined whether the tailwater treatment pool that has been started has exceeded the treatment line. At the same time, the microbial influence coefficient is compared with the upper limit of the microbial influence coefficient to determine whether it has exceeded the upper limit of the microbial influence coefficient. In this way, the microbial influence is combined with the pollution load as one of the reference factors for considering the treatment capacity of the tailwater treatment pool, avoiding only considering the treatment load capacity of the tailwater pool and ignoring the influence of microorganisms under temperature, which leads to a decrease in the ability of the tailwater pool to treat sewage. This controls the number of tailwater treatment pools that are started and achieves a reasonable number of tailwater treatment pools.

[0028] The quality data analysis and processing unit sends the generated signals for starting all tailwater treatment pools, generating signals for starting multiple tailwater treatment pools and signals for closing some tailwater treatment pools to the tailwater treatment pool control unit. When the tailwater treatment pool control unit receives the signal for starting all tailwater treatment pools, it starts all tailwater treatment pools. When the tailwater treatment pool control unit receives the signal for starting multiple tailwater treatment pools, it starts some tailwater treatment pools. When the tailwater treatment pool control unit receives the signal for closing some tailwater treatment pools, it closes some tailwater treatment pools.

[0029] By calculating the real-time load of the tailwater treatment pool, the overall treatment capacity of the tailwater treatment pool, the tailwater treatment efficiency, and combining the environmental factors of the tailwater treatment pool and the main pollutants in the tailwater treatment pool to calculate the microbial influence coefficient, and comparing these values ​​with the upper limit threshold of the corresponding data, and combining the actual environmental factors to comprehensively judge whether it is necessary to increase the start-up of the tailwater treatment pool or shut down some tailwater treatment pools, it is possible to automatically control the start-up or shutdown of multiple tailwater treatment pools based on the real-time load status of the tailwater treatment pool and the factors affecting microorganisms in the current environment, thereby reducing manual monitoring of equipment at each treatment stage, reducing the need for professional knowledge reserves of operators, and reducing operational difficulty and labor costs.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
