The present invention relates to a water purification system for fish farms and a water quality management system for optimally controlling the operation of water quality improvement mechanisms including such water purification systems. More specifically, the water quality of fish farms is constantly measured and contaminants from ponds are continuously measured. The system relates to a system for taking timely water quality improvement measures to remove water, clean water, reuse water, and maintain water quality at a set value. In addition, the present invention also provides a fish farm remote management system that provides integrated control of a number of pond-based water quality management systems in fish farms, and provides water quality information and observation information observed by a separate fish farm management system to managers and other information consumers. do.

Common elements that make up the quality of fish farms are dissolved oxygen concentration, water temperature, pH (pH), ammonia concentration, nitrogen compound concentration, nitrite concentration, turbidity, etc. Among them, dissolved oxygen concentration and water temperature are the most important.

The main sources of pollution that hinder fish farming are the excreta, carcasses and leftover feed from farmed fish. In other words, since pollutants exist as necessary evils that cannot be avoided, it is impossible to block them, and improvement measures such as removing pollutants in a timely manner and injecting water quality improvement agents are required while continuously monitoring the water quality.

Primitive water quality improvement measures include using a stirring device to disturb the water stored in the pond to generate foam, thereby controlling the oxygen infusion to dissolve oxygen in the air, and adjusting the mixing ratio of the hot and cold water to be introduced or using a heater. It was to control the heated water temperature, replace the water to remove contaminated water from the pond, and introduce pond cleaning, and periodically clean the pond to remove contaminants that settled on the bottom of the pond.

Since oxygen injection and water temperature control are very important, it is an additional device to inject high purity oxygen or improve the performance by using heater or boiler instead of injecting oxygen in the air to maintain the quality of water optimally. Is necessary.

Water replacement and pond cleaning were not expensive and the side effects were small, so there was not much research and effort to improve the efficiency or to prepare alternatives.

In other words, the replacement of water requires the consumption of a large number of new athletes, and the pond cleaning causes the contaminants at the bottom of the pond to float, causing excessive turbidity of the water, resulting in the death of fish or disease.

Therefore, there is a need for a water purification system that can improve water quality while minimizing fresh water consumption by efficiently removing contaminants and reusing and reusing water.

On the other hand, dissolved oxygen concentration in the water should be constantly maintained at the optimum level. In other words, when the dissolved oxygen concentration is lowered, the fish may not eat well, cause indigestion, or may be stressed to slow down growth, and in severe cases, may cause massive fish death. On the contrary, even if the dissolved oxygen concentration is excessively high, it may cause diseases such as foaming of fish and waste of oxygen injection cost. Furthermore, even if the change is within acceptable limits, the fish will be stressed and diseased if the dissolved oxygen concentration fluctuates severely.

Therefore, there is a need for an oxygen infiltration control that continuously monitors the dissolved oxygen concentration in the water and injects an appropriate amount of oxygen into the water to maintain the dissolved oxygen concentration at an optimal level at all times.

Water temperature has a huge impact on fish growth. Although the proper water temperature is different and the sensitivity to water temperature varies depending on the species, it is required to maintain the water temperature under optimum growth conditions in order to increase the productivity of the fish, regardless of the species.

Therefore, there is a need for a rapid heat control that continuously monitors the water temperature of the water and operates the heater in a timely manner or adjusts the mixing ratio of cold and hot water to maintain the water temperature at a constant level.

Conventionally, a measuring instrument for measuring dissolved oxygen concentration or water temperature is installed in each pond, and fisheries managers patrol from time to time to check the measured value and check the turbidity of the water while replacing the water while operating oxygen injector, heater or boiler. I've cleaned the pond. However, fish farm management in this manner is difficult to maintain a constant level of dissolved oxygen concentration or water temperature at all times, even if huge efforts are required.

Therefore, by continuously monitoring the water quality, timely operating the above water purification system, oxygen injecting means, or water temperature control means to maintain the dissolved oxygen concentration and temperature at a constant level and to maintain the water quality optimally. Management is required.

Automating such water quality management will ultimately enable remote management that can be managed by fish farm managers without residing in fish farms.

Remote management requires not only information about the operational and water quality of the water quality management system to be delivered to the manager in real time, but also about whether there are external invaders in the fish farm or the activity and rearing conditions of the fish in each pond. Observation information should also be communicated.

Such observation information may be used as product information that enables the consumer to check and purchase the growth status of fish at a remote location without visiting the fish farm.

As described above, the present invention is to meet the optimum growth conditions necessary for rearing fish, thereby improving the productivity of high quality and solving the need for efficient fish farm management.

As shown in FIG. 1, the fish farm remote management system according to the present embodiment includes means 210 for acquiring water quality management systems for ponds (100, 100 ', 100 ") and observation information regarding the situation around the fish farm and outside the pond. Means 220, 220 ', 220 "for obtaining observation information about the situation in each pond. The pond water quality management system (100, 100 ', 100 ") is connected to the main controller 300, the main controller 300 is connected to the fish farm control computer 400.

As a fish farm control computer 400, a personal computer (PC) is used, and as the main controller 300, a control system based on a microprocessor is used.

Observation information acquisition means (210, 220, 220 ', 220 ") includes one or more CCD cameras installed to photograph the surrounding fishery, the view of the inside and outside of the pond and the fish rearing state in the pond and to transmit to the fish farm control computer 400, In addition, it may include an infrared sensor for detecting an intruder.

The pond-specific water quality management system (100, 100 ', 100 ") according to this embodiment are all configured identically, as shown in Figure 2, each of the oxygen injecting means 110 to dissolve oxygen in the water, Water temperature control means 120 for heating or cooling the water, the water quality sensor 130, the input unit 140 used to input the set value and the allowable limit of the required water quality state, and remove the contaminants in the pond Water purification system 500 to purify the water, and the oxygen injection means 110 and the water temperature control in accordance with the water quality state detected by the sensor 130 and maintaining the set value of the water quality state input from the input unit 140 A lake water quality controller 101 for timely operating each of the means 120 and the water purification system 500.

Water temperature control means 120 according to this embodiment uses a boiler (not shown) as a heat source and the ground water as a cooling source. However, in the present invention, since the water in the pond is rarely replaced, the temperature change of the water is not so severe, and only the temperature change caused by the change in the temperature of the atmosphere needs to be compensated.

The water quality sensor 130 used in this embodiment is a dissolved oxygen amount sensor 131 and a temperature sensor 132. However, an acidity sensor, an ammonia concentration sensor, a nitrogen compound concentration sensor, a nitrite concentration sensor, or the like may be additionally installed. In addition, the dissolved oxygen sensor 131 and the temperature sensor 132 may be appropriately positioned at an appropriate position to obtain an average and representative measurement value in consideration of the shape of the pond, the flow of water in the pond, or the depth of water stored in the pond. Can be installed in number.

Like the main controller 300, the lake water quality controller 101 uses a microprocessor-based control system.

The input unit 140 may be configured to be attached to a control system used as the lake water quality controller 101 or may be configured to be attached to a control system used as the main controller 300. Alternatively, the present invention may be configured to be duplicated in both, or may be configured to be input from a PC used as the fish farm control computer 400.

Pond cleaning means (510) is a water rotation means for forming a water flow that rotates in one direction along a concentric circle centered on the center of the pond, and pumping water to draw water with contaminants near the bottom of the pond center Means and contaminant filtration means for filtering contaminants from the pumped water.

As shown in Fig. 4 to 6, the water rotation means is composed of a water supply nozzle for discharging the water of high pressure in one direction perpendicular to the line connecting the water supply position in the pond and the center of the pond. That is, the water supply pipe 511 is erected vertically with its tip near the bottom of the pond, and its tip is blocked, and a plurality of holes 512 are lined up at regular intervals along the length of the water supply pipe from near the tip. Perforated The water supply pipe 511 is disposed so that the hole 512 faces in a direction perpendicular to a line connecting the water supply pipe and the pond center. Preferably, the pond is formed in a circle. As shown in the figure, when water is discharged through the holes 512 of the water supply pipe 511 arranged, the water stored in the pond rotates clockwise. Due to the rotation of the water, the contaminated water in the pond collects in the center of the pond and settles on the bottom. In addition, this spring rotation also has the side effect of causing proper movement of the cultured fish.

The pumping means includes a pumping pipe 513 disposed obliquely with the suction port 514 at the bottom of the pond. Near the inlet 514 of the pump 513 is wrapped with a filter 517 made of a grid smaller than the size of the fish to prevent fish from being sucked in.

The filter 517 is made of about 5 grooves of 5 mm in three places at 120 degrees to prevent the fish from entering the inlet so that water can be introduced.

The contaminant filtration means includes a primary filter 515 consisting of a wire mesh filter for filtering coarse contaminants from water falling from the outlet of the pump pipe 513 and a secondary filter 516 for filtering fine contaminants from aberrations and high-pressure air.

Between the oxygen check valve 115 and the oxygen pressure sensor 116 is disposed. The water supply conduit 532 is disposed with a pump pressure sensor (not shown).

In order to increase the efficiency in which the vaporized oxygen is dissolved in the water, a conical dissolver 117, as shown in FIG. 5, is used. The bottom end of the conical melter is perforated with seven holes, 50 mm in diameter, with openings downwards in the pipe, which allow oxygen dissolved water to exit the outlet.

That is, the water is sucked together with the contaminants through the inlet 514 of the pumping pipe 513 and is purified and supplied while communicating with the primary filter 515, the secondary filter 516, the reservoir 521, and the septic tank 522. The water pipe 532 and the water supply pipe 511 circulate in a manner that is returned to the pond.
