値に維持していくことは、困難なことである。2. Description of the Related Art In recent years, there has been an increasing number of opportunities for so-called live fish transportation, in which fish and shellfish are transported alive using a truck or the like. Generally, in order to survive seafood in an aquarium or aquaculture pond, it is necessary to manage and maintain water temperature, dissolved oxygen content, carbon dioxide partial pressure, and ammonia concentration at appropriate values. For squid and other cephalopods, in addition to this, nitrate and nitrite concentrations must be controlled. However, in transporting live fish, in order to improve transport efficiency, we try to transport with as little water as possible, so the density of individuals in the aquarium becomes high, and the environmental factors such as the amount of dissolved oxygen and the concentration of ammonia described above are set to appropriate values. It's difficult to maintain.

質管理が必要である。Further, in a state where a great deal of stress is exerted on seafood such as transportation of live fish, resistance to deterioration of the above environmental factors is weakened, and for example, the ammonia concentration is 1 mg / l or less in a normal state. However, it is necessary to maintain a low concentration of 0.3 mg / l or less when transporting live fish. For this reason, stricter water quality control than in normal conditions is required.

It has been adjusted by performing aeration,
Ammonia has been regulated by converting it into nitrates and the like, which are less harmful, using a filter device that uses a filter medium to which nitrifying bacteria are attached.

なことを行うことは、極めて困難なことである。However, since the above-mentioned method for controlling ammonia using nitrifying bacteria utilizes an oxidation reaction using microorganisms, the water temperature and the amount of dissolved oxygen are maintained in appropriate states. I have to do it. Therefore, in order to effectively remove ammonia, it is necessary to comprehensively control the water temperature, the amount of dissolved oxygen, and the concentration of ammonia, but this is done in trucks, etc. during transportation of live fish. That is extremely difficult.

A method for controlling the concentration of anaerobic bacteria is known, but it is difficult to use for transporting live fish because a large space is required for culturing the anaerobic bacteria. An object of the present invention is to provide a system for effectively removing ammonia even in the process of transporting live fish by comprehensively controlling and adjusting water temperature, dissolved oxygen amount and ammonia concentration, which are important factors for survival of fish and shellfish. ,
Another object of the present invention is to provide a system having means for removing nitrates and the like which are harmful to cephalopods.

The information is sent to the control device 5. The dissolved oxygen amount in the water tank is measured by the dissolved oxygen amount measuring device 3. As the dissolved oxygen amount measuring device 3, either a magnetic type device or a redox type device can be used, but here a small and lightweight redox type galvanic cell type oxygen sensor is used. As shown in FIG. 2, the galvanic cell type oxygen sensor includes an outer cylinder 301, a diaphragm 302, an electrolytic solution 303, an anode 304, and a cathode 305. Dissolved oxygen in the water tank permeates the diaphragm 302, and the diaphragm 302 and the cathode 305.
It is dissolved in the electrolytic solution 303 between and and is reduced on the surface of the cathode 305. On the other hand, since lead is oxidized at the anode 304, a current flows between the anode 304 and the cathode 305. This current is proportional to the oxygen concentration, so that the oxygen concentration can be measured. Information about the amount of dissolved oxygen thus measured is sent to the controller 5 as well as the temperature.

When the temperature is higher than the set temperature range by operating the heater 7, the cooler 8 is operated to lower the temperature. Further, when the value measured by the dissolved oxygen amount measuring device 3 is lower than the set range, the output of the aeration device 6 is increased to increase the dissolved oxygen amount, and when it is higher than the set range, the aeration device. The output of 6 is reduced to reduce the amount of dissolved oxygen.

の製造するには以下のような方法で行えばよい。The ammonia concentration in the water tank is measured by the ammonia concentration measuring device 4. As the ammonia concentration measuring device 4, any known device may be used, but here, since the operation is simple, ammonium applied previously by the inventors of the present application (Japanese Patent Application No. 3-142503) Use an ion concentration detector. As shown in FIG. 6, this is composed of an outer cylinder 41, a gas permeable diaphragm 42, a measurement electrode 43, a comparison electrode 44, an electrolytic solution 45, a power supply 46, a cathode 47, and an anode 48. When a current is applied between the cathode 47 and the anode 48 by the power supply 46, the pH in the vicinity of the cathode 47 rises and ammonium ions become ammonia gas. The gasified ammonia is
After passing through the gas permeable diaphragm 42, it dissolves in the electrolytic solution 45 and becomes ammonium ions again. As a result, a potential difference is generated between the comparison electrode 44 and the measurement electrode 43, and the ammonium ion concentration in the water tank can be measured from this potential difference, and the ammonia concentration can be known. The information on the ammonia concentration measured in this way is sent to the control device 5. In the control device 5, the reference ammonia concentration can be set. When the measured value of the ammonia concentration is equal to or higher than the reference value, the control device 5 increases the output of the pump 10 and circulates it to the ammonia removing device or the like. Increase the amount of water. Further, in order to enhance the ability to purify ammonia such as nitrifying bacteria, the output of the aeration device 6 is increased to increase the amount of dissolved oxygen, and the heater 7 is operated to raise the temperature within the set range. The ammonia removing device 11 may be a known filter device in which nitrifying bacteria are attached to and proliferate on the filter medium, but here, as the filter medium, as shown in FIG. 7, the small pores have diameters of 0.1 to 1 μm and 10 μm. Use a filter material made of porous ceramics distributed in ~ 100 μm. The following method may be used to manufacture such a filter medium.
