が重要である。(Prior art and its problems) In recent years, aquaculture of fish and shellfish has become increasingly popular, and the forms range from small-scale cultivation using aquariums and aquaculture ponds.
A variety of methods are being implemented, including large-scale efforts to use the ocean itself as a cattle pen. In all of these aquaculture cases, water quality management in the aquaculture zone is important.
そのため、養殖ゾーンへの種々の薬液の散布が行なわれ

異常発生時に散布するものの両者があるが、いずれの場

されることが望ましい。Therefore, various chemical solutions are sprayed onto the aquaculture zone. For example, various medicinal solutions are known, such as drugs for suppressing the occurrence of various pathogenic bacteria, drugs for replenishing various nutritional components, and drugs for suppressing the occurrence of red tide. Such chemical solutions are sprayed regularly, or
Both methods are sprayed when an abnormality occurs, but in either case, it is desirable that the chemical solution be spread evenly and effectively over the entire area of the aquaculture zone.

す恐れがあり好ましくない。However, in the past, the common method for dispersing these chemicals was to spray them from the atmosphere onto the water surface of the aquaculture zone using a jet pump, etc. However, in this method, the chemicals were scattered by the wind, and the chemicals were Not only was there a loss, but it was also difficult to uniformly spray the aquaculture zone. in short,
When spraying a chemical solution from the air, it is difficult to uniformly spray it on the water surface, and naturally the concentration is high at the surface of the liquid, but the concentration is low at the bottom, making it almost ineffective. It becomes impossible to do so. Although these problems can be solved to some extent by increasing the amount of chemical solution sprayed, this is not preferred because it is not only economically disadvantageous, but also may cause concentration disturbances due to the drug.

The present inventors have discovered that extremely effective chemical liquid supply can be achieved by installing the system underwater and injecting the chemical liquid into the aquaculture zone using a pump, and have completed the present invention.

の供給方法に存する。That is, the gist of the present invention is that a chemical liquid injection part formed of a porous body installed in water is connected to a chemical liquid tank by a pipe, and the chemical liquid is supplied into the liquid by force-feeding the chemical liquid with a pump. The problem lies in the method of supplying the chemical solution to the aquaculture zone.

果的である。The aquaculture zone A is usually of any type, such as an aquarium, a pond, or a farm for cattle using the ocean, and its scale is not particularly limited, but it is more effective if it is relatively large.

ためシラン処理した物も使用できる。The chemical liquid injection part 1 is constituted by a porous membrane having a large number of pores having at least a millimeter or less in diameter. This porous membrane usually includes porous glass membranes, porous ceramic membranes such as porous alumina membranes, porous metal membranes such as porous stainless steel membranes, porous synthetic resin membranes such as porous polyimide membranes, porous polyethylene membranes, etc. However, in the present invention, porous glass membranes are particularly preferred in terms of corrosion resistance, weather resistance (T: external radiation resistance), and pore size. That is, in the case of a porous glass membrane, since glass is the main component, it is highly resistant to chemical solutions, and the pore diameter is small, ranging from several tens of angstroms to several microns, so it is preferable. In this case, since there is a "threshold" that prevents the internal chemical solution from flowing out unless a pressure higher than a predetermined level is applied, there is no fear that the chemical solution will naturally flow out. As this porous glass membrane, a commercial product manufactured by Ise Chemical Co., Ltd. under the trade name MPG pipe, and a commercial product manufactured by Fuji Davison Chemical Co., Ltd. under the trade name PSG pipe can be used. Also, those whose surfaces have been treated with silane to make them hydrophobic can also be used.
薬液噴射部１の形状は通常、円形のパイプ状のものであ

２０〜１００ｃｍ程度である。また、その膜厚は通常、
０．５〜１．０ｍである。The shape of the chemical liquid injection part 1 is usually a circular pipe shape, and its size is determined depending on the scale of the aquaculture zone A, etc., but usually the diameter is about 10 to 30 Irvn and the length is about 20 to 100 cm. It is. In addition, the film thickness is usually
It is 0.5-1.0m.

Usually, depending on the volume of the aquaculture zone A, a plurality of them can be divided two-dimensionally and three-dimensionally and installed at separate locations. However, in this case, each medicine injection part 1
Both of them extend separately from a connecting pipe connected to the chemical liquid tank 2 at the upstream side.

、１５〜５０ｍ程度である。In addition, a press pump 3 is provided in the middle of the connecting pipe 4 to pump the chemical liquid in the chemical liquid tank 2 and to supply the chemical liquid into the water from the chemical liquid injection part 1 at the tip. The pressure in this press-in pump 3 needs to be above a certain pressure (threshold value), and if this pressure is low, the chemical solution cannot be pushed out from the porous surface of the chemical solution injection part. This pressure is determined by taking into account the lengths of the connecting pipe 4 and the chemical liquid injection section 1, as well as the viscosity of the chemical liquid. Further, the diameter of the connecting pipe 4 is usually about 15 to 50 m.
タンク２内の薬液はその用途に応じて種々のものが挙げ
られ、例えば、殺菌剤、栄養剤、ｐＨ調節剤、その他薬
液及びこれらの混合物が挙げられる。なお、場合により
、異なる薬液タンクの薬剤を各々、切り換えて養殖ゾー
ンＡに供給することも可能である。Various types of chemical solutions can be used in the tank 2 depending on their uses, such as disinfectants, nutrients, pH regulators, other chemical solutions, and mixtures thereof. Note that, depending on the case, it is also possible to switch the chemicals in different chemical liquid tanks and supply them to the aquaculture zone A.
また、本発明では薬液の供給に際して、連結バイブ４の

にできるので望ましい。Furthermore, in the present invention, when supplying a chemical solution, by introducing air (or oxygen) from the middle of the connecting vibrator 4, the chemical solution and air can be supplied in a mixed phase state from the chemical solution injection section 1. This method is desirable because the chemical solution can be more effectively diffused into the aquaculture zone, and oxygen can also be supplied to the water at the same time.
なお、薬液の供給は連続的でも、間けつ的でも差し支え
ない。Note that the chemical solution may be supplied continuously or intermittently.
