Description

Circulation filtration aquaculture system for land aquaculture.

The present invention relates to a circulating filtration aquaculture system for an onshore farm, comprising: a breeding tank having a floor and an outer wall of a certain area and capable of accommodating aquaculture organisms and breeding water; a breeding water management system for sensing and measuring breeding water by collecting breeding water in the breeding tank; The breeding tank and the breeding water management system are connected via a breeding water inlet pipe; It relates to a circulation filtration aquaculture system for onshore farms comprising a drain pipe installed at the bottom of the breeding tank.

In general, a relatively large amount of fish is cultured at a high density based on a limited space and quantity in a land farm. Due to this, not only various solid components such as feed residues or excrement of farmed fish, but also protein components, ammonia components, and carbon dioxide components generated in the metabolic process of farmed fish are accumulated in breeding water within a very short time, and breeding water is easily contaminated.

Accordingly, in land-based indoor aquaculture farms, there are a sedimentation tank that sediments and removes solids in the breeding water discharged from the aquaculture tank and degassing carbon dioxide, and a biological filtration tank that removes ammonia and nitrogen components from the breeding water by microorganisms. The circulation filtration system of the included breeding water is widely used. In the aquaculture circulation filtration system, the microbial filtration treatment may be performed after the primary solid matter filtration treatment is performed, and the filtration treatment may be performed in the reverse order. A system is disclosed.

Aquaculture water quality management is important in the circulation filtration system. Factors constituting the water quality of aquaculture farms include dissolved oxygen concentration, water temperature, acidity (pH), ammonia concentration, nitrogen compound concentration, nitrite concentration, and turbidity. There is food left over from eating. That is, pollutants are fundamentally difficult to block, and in particular, in the circulation filtration system where breeding water is reused, it is necessary to remove pollutants in a timely manner while monitoring the water quality and take improvement measures to improve water quality.

The main purpose of the breeding water management system of the conventional purifying filtration system is to measure and provide basic water quality information such as water temperature, salinity, and dissolved oxygen to the manager. Since they are different from each other, there is a problem in that it is difficult to optimize the management of farmed items, so it is directly related to an increase in production cost and a decrease in shipment, which can cause a decrease in aquaculture efficiency and water pollution around the farm due to excessive feed.

Accordingly, along with the development of a farm breeding water management system to which the Internet of Things system is applied, so that the information on the amount of feeding, disease outbreak information, oxygen supply amount information, and information on the predicted timing of red tide can be calculated and immediately provided to the manager according to the change in the water quality information of the farm. Domestic Patent Publication No. 10-2012-0076683 also discloses a related farm management system.

Specifically, the farm automatic water quality management device to which the system is applied includes a communication unit that receives water quality data or risk element detection data from a water quality measuring device installed in each of the plurality of tanks, the size of the tank, the type of fish, the growth degree of the fish, the tank A storage unit for storing tank information including at least one of a phone number and an address of a user terminal associated with a storage unit for classifying and storing the received water quality data or risk detection data by fish type, and water quality measurement mounted on the plurality of tanks When the amount of change of the water quality data received from any one of the devices is greater than the reference value or when the risk element detection data is received, a control unit for transmitting a notification signal to the user terminal corresponding to the water tank may be included.

However, the water quality sensor installed in the device is made of a manpower type, an underwater installation (mounting) type, a pipe type, or the like. The manpower type is a method in which a measurement person collects seawater (freshwater) directly or drops a sensor to a specific depth to measure it. way to install it. The manpower type is 100% dependent on the measurer. In the underwater installation type, it is inconvenient to clean or calibrate the sensor, and it is difficult to periodically clean and calibrate the sensor, which shortens the sensor's lifespan, which can be an economic burden. There is a problem that causes a burden. In the conduit type, not only is the sensor not automatically cleaned and calibrated, but since most sensors are installed in one conduit, it is difficult to collect breeding water at various depths or locations, so it is necessary to develop a device capable of solving the above problems.

The breeding water inlet pipe can be installed in one or more breeding tanks, so that the length of the breeding water inlet pipe is different for each water level of the breeding tank, so that water can be collected for each breeding tank water level.

For water quality measurement in the existing aquaculture farm, it was a 1:1 method in which one sensor set was applied only to a single farm. However, according to the present invention, more than one breeding water inlet pipe can be installed in a single farm, and by extending the inflow pipe and installing it in a nearby farm, the collection of breeding water for sensing is possible in a 1:n method. It is possible to reduce the burden of increased facility cost by method 1.

The existing sensor for monitoring water quality is fixed to the farm, making it almost impossible to clean. In particular, the ultrasonic cleaning method can cause frequent failures and shortened lifespan, such as shortening the lifespan of the optical sensor, peeling of the measuring optical lens film, etc. After cleaning each sensor, the cleaning solution and correction solution are sprayed inside the measuring chamber by the microbubble jet method, and then they are recovered as a storage solution, or each cleaning solution and correction solution are stored in the calibration solution chamber and the cleaning solution chamber of the tank structure, resulting in contamination and freezing. There is little risk.

In the breeding water management system of the present invention, when the user sets the target water depth of the breeding water tank directly to the control unit or using the user terminal and executes a control command, the motor pump operates and the breeding water is sampled from the breeding water inlet pipe installed at the water depth. do. Accordingly, the sampling number of breeding introduced into the measurement chamber is sensed and measured by the sensor unit, and the measurement time and measurement interval of the sensor unit may be controlled by the main controller receiving the set command value from the control unit.

The sampled breeding water that has been measured is re-introduced into the breeding tank as the valve of the re-introduction pipe controlled by the main controller is opened. can be done The cleaning liquid and the correction liquid may be automatically recovered to the cleaning liquid injecting unit and the correcting unit under the control of the main controller after washing by spraying, or may be discharged to the outside of the device.

The above process is carried out in a 1:n method of one or more installed breeding water inlet pipes and independently with a command set under the control of the main controller, so that it is possible to more accurately monitor the water quality for each breeding water depth. Sensors installed in conventional aquaculture farms have difficulties in measuring method and calibration and cleaning of the sensors.
