ればならないので、設儲費の点で本利益を生じる。Physical filtration is a function that uses activated carbon, zeolite, etc. as part of the filter media to adsorb ammonia etc. that are harmful to fish.
Biochemistry a-tsu refers to the function of aerobic nitrifying bacteria attached to filter media to decompose and purify them. If you compare physical filtration and biochemical filtration, biochemical filtration is far superior in terms of purification ability and continuity, and biochemical filtration is the main source of purification in a filtration circulation type aquarium. Therefore, the filter medium placed in the filter tank is made of silica sand, which is suitable for aerobic nitrifying bacteria to adhere to, inhabit, and reproduce. Coral sand. Branch corals are used. Aerobic sheathing bacteria play an important role in converting harmful ammonia, which is released by the decomposition of excrement and leftover food from fish, into nitrite by combining it with oxygen, and then converting it into nitric acid and nitrate, which are harmless to fish. do. Therefore, the purification ability of a filtration tank circulation type aquarium is determined by the number and activity of aerobic bacteria that adhere to and live on the grass in the ill'a tank. Filter tank circulation type aquariums are based on the above-mentioned purification principle and are used as aquariums for aquaculture, livestock stocking, and ornamental purposes, but they have the following problems in terms of maintenance and management of the filtration tank. be. As mentioned above, the purification function of the filtration tank depends on aerobic nitrifying bacteria, but when a new filtration tank circulation type aquarium is installed, aerobic nitrifying bacteria will be present in the filtration material in the filtration tank. There is a disadvantage that only a small number of fish can be placed in the tank for one month until they are fully bred in the filter medium. During this process, the filter media becomes clogged, so it is necessary to clean it periodically, but the following inconveniences occur when doing so. The cleaning method for the filter media is to take the filter media out of the small II1t filter tank, thoroughly wash it with tap water, and then return it to the filter tank6.In medium and large filtration tanks, there is a large amount of filter media. In many cases, a so-called backwashing method is used in which the filter medium is washed by injecting air or water in the opposite direction to the filtration direction without removing the filter medium. Cleaning these filters is absolutely necessary in order to wash away harmful substances, eliminate clogging, and ensure 1 minute circulation, but at the same time, cleaning the filter media also eliminates adhesion to the filter media. Most of the aerobic nitrifying bacteria that live in the tank are washed away or die, resulting in a significant drop in the purification ability of the filter tank, and the purification ability does not fully return to its original level after about a month has passed. This inconvenience arises. This means that if you are trying to raise fish continuously in a single large-scale aquarium, such as for breeding or stockpiling, this will cause a huge amount of damage, and you should prepare a large pre-steeled aquarium in advance. Since the equipment must be maintained, the main profit is generated in terms of setup costs.

を用いて空気を混入させる。Specifically, the aim is to supply filter media pre-cured with aerobic nitrifying bacteria, which should be placed in the filter tank when an illll circulation type water tank is newly installed or when the filter media is cleaned. It is something. Figure 1 is a schematic process flow diagram of the manufacturing method of the present invention. In the filter tank (1.), filter media such as silica sand, coral sand, branch coral, etc., to which aerobic nitrifying bacteria are attached, inhabited, and propagated using this manufacturing method, are placed. The shape of the filter paddle (1) has a large flat area and a shallow height, with a diamond (1) section.
2) to make it easy to put in and take out the filter media. The water to be circulated in the filtration tank (1) should be seawater or freshwater, depending on whether it is a water fence for Taobing fish or freshwater fish. The circulating water injected from the top of the filtration tank (1) is uniformly applied to the filter phase through the sprinkler pipe.
Let it be poured. The circulating water that has passed through the filter medium is discharged from the T part of the filter tank (1), and is sent to the heater (3) and cooler (4).
) and receives the water temperature gu. After that, the circulating water is pressurized by the circulation pump (6) and returned to the in-tub tank (1>)4.The flow rate of the circulating water is adjusted by the flow rate adjustment valve (7)7.The nutrients for the aerobic nitrifying bacteria are Injection pump (9) and regulating valve (10) from the ammonia water tank (8゛) that stores the ammonia water.
through which it can be directly injected into the circulating water return pipe or the m-through fence (1). Aerobic nitrifying bacteria consume oxygen, so the blower (eyes) filters the filter tank (1
), or use an ejector to mix air into a part of the circulating water piping.

能力を継続させることができる。In addition, the quantitative addition of l-ammonia water can be easily automated, and the operation of the equipment used in this production method does not require much manpower. Furthermore, since the ammonia water is only added to the filter medium, the bacteria-cured filter material is extremely clean and easy to handle. The second VF feature is a blower or ejector to supply essential oxygen to the aerobic sheathing bacteria, and a heater/cooler to maintain the temperature suitable for the growth of aerobic nitrifying bacteria. Since it is equipped with a container, the period for curing the strained material with bacteria is shortened. It is also possible to raise cold-water fish and warm-water fish, respectively, and adjust the temperature of the water in the aquarium to acclimate the aerobic nitrifying bacteria to those water temperatures before using them as filter media. The filter media with bacteria-clogged cells according to the present invention is used as described in 1. When it is necessary to put a variety of fish into an aquarium, by straining the filter material used in the filtration tank and adding some or all of the tlNA that has been cultured with bacteria using the production method of the present invention, it is possible to achieve the desired purpose. This is because aerobic nitrifying bacteria with a sufficient number and activity are already attached and living on the filter media that has been cultured with bacteria using the production method of the present invention, and has a high purification ability. In addition, in order to solve the problem of the extraneous low F of the desalination ability during filter media cleaning, in a small filtration tank, after the filter media is removed from the tank, bacteria are cured using the manufacturing method of the present invention. By inserting filter media and replacing the old filter media, it is possible to demonstrate the ability to purify birds, and it will not have a negative impact on the fish being raised for cultivation, stockpiling, or ornamental purposes. When cleaning the filter media by backwashing, as in the case of backwashing, a portion of the filter media is removed after backwashing, and the filter media cured with bacteria using the manufacturing method of the present invention is put in its place, so that the purification ability can be maintained in the same way. be able to.

義と言えよう．In addition, after thoroughly washing the removed fortune-telling filter medium with tap water, it can be placed in the bacteria-curing filter tank of the present invention to eliminate bacteria. ! The present invention does not consume the filter material, as it can be used again as a filter material. In this way, the owner of a filter tank circulation type aquarium can freely use the filter medium that has been cured with bacteria using the manufacturing method of the present invention, without causing a decrease in the purification ability (i.e.
1II It becomes possible to maintain and manage the tank, and it is extremely beneficial for management when the purpose is to grow fish stably over a long period of time, such as in aquariums for aquaculture or profit storage. As described below, the present invention improves the method of manufacturing a bacteria-cured filter medium that facilitates the maintenance and management of the filter tank of a filter tank refrigerating type water tank and improves the 4R reliability, and is extremely useful.
It can be called righteousness.
