Problems solved by technology

[0007] As mentioned above, although the water quality evaluation of the breeding pond, the device for purifying the water quality, and the water quality monitoring system of the water tank are known, but there is no accurate grasp of the environmental state of the breeding pond, the prediction of the tendency of the water quality of the pond to deteriorate, and the need to notify in advance. Technology or device for changing pool water period

Embodiment 1

[0061] Embodiment 1 monitors changes in ammonia concentration for a certain period of time (in daily units), predicts a predetermined value based on the change of the concentration so far, and notifies water replacement (limit life of the pool) in advance. For example, by using an analysis unit, it is possible to predict the time txx when the ammonia concentration reaches the reference value XX indicating deterioration of water quality based on the increase rate of the ammonia concentration at the time tx notified in advance.

[0062] Specifically, from Figure 4 It can be seen from the change of the ammonia concentration that the ammonia concentration changes to a low value from the breeding period, and the replacement time of water cannot be predicted during this period. However, if the ammonia concentration starts to rise, it is possible to predict the time txx when the ammonia concentration reaches the reference value XX indicating deterioration of water quality at the tim...

Embodiment 2

[0064] Embodiment 2 monitors the change of the pH value on a daily basis, predicts that the value will become a predetermined value, and informs the water change period txx in advance. Similar to the reference value XX in which the ammonia concentration represents deterioration of water quality in Example 1, the time txx when the pH value reaches the reference value can be predicted and notified in advance. During the breeding period before the water quality of the breeding pond deteriorates, when the predicted value of the pH value tends to decrease, the water quality management device 1 can display an indication to add a pH regulator (calcium carbonate, baking soda, etc.), and when there is a tendency to increase, it can be displayed to proceed. Instructions for replacement of water and removal of deposits. As mentioned above, in the nitrous acid feeding method, in Figure 4 At point C of the fluctuation of the pH value in (A), calcium carbonate is put into the pool to adju...

Embodiment 3

[0066] Embodiment 3 monitors the change of ORP with a certain period of time (in units of days), and when the decrease of the value is continuously monitored, the oxidation capacity of the pool is notified, which is close to the replacement of water (the limit life of the pool) period. When the ORP exceeds 300 mV, the pH value becomes 5.5 or less, and there is a high possibility that the oxidation reaction is less likely to occur, so a pH adjuster is added.

[0067] In association with Embodiment 3, Figure 5 It is a graph showing changes in pH and ORP (Oxidation Reduction Potential). Depend on Figure 5 It can be seen that the ORP fluctuates repeatedly between positive and negative, but thereafter, after the period T in which the culture is continued in a state where the ORP is negative, a tendency for the pH to rise is observed. This state indicates that the life of the culture pond will be exhausted (close to the limit life). Therefore, by monitoring the ORP and detecting...

Abstract

Provided is a water quality management device for a culture pond, comprising: a storage unit for storing measured values relating to water quality measured at appropriate time intervals by an external sensor provided in the culture pond, a determination unit for calculating future predicted values on the basis of variations in the measured values, and a display unit for displaying the predicted values; and a determination unit that determines a period at which the predicted value exceeds a reference value indicating deterioration of water quality, and that displays the period at which the predicted value exceeds the reference value, the period being a period at which the pool water needs to be replaced.

Description

technical field [0001] The invention relates to a water quality management device and method for a culture pond. Background technique [0002] Regarding the water quality management of a culture pond, the water quality evaluation method of a culture pond shown in patent document 1 is known. The water quality evaluation method provides a water quality evaluation method and a water quality checklist for maintaining carp health by using oxidation-reduction potential as an index for evaluating the water quality of carp culture. However, this method judges the current water quality only by using the redox potential as an indicator, and does not grasp the tendency of future water quality deterioration and inform the replacement time of the pool water in advance. In addition, since it is a special example such as a concrete culture pond, and water quality conditions are also different, it is difficult to apply to a natural culture pond surrounded by soil. [0003] The water quali...
