以下、本願発明について、図面を参照しながら詳細に説明する。なお、本発明は実施例に限定されるものではない。   Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to an Example.

ここで、水生生物とは、淡水性の魚、貝など、水中に生息する生物である。本発明である水耕栽培を備える水生生物の養殖システム1は、図1、2に示すように、建屋2と、養殖部3と、送水部4と、浄化部5と、水耕栽培部6と、からなる。   Here, aquatic organisms are organisms that live underwater, such as freshwater fish and shellfish. As shown in FIGS. 1 and 2, an aquatic organism culture system 1 equipped with hydroponics according to the present invention includes a building 2, a culture unit 3, a water supply unit 4, a purification unit 5, and a hydroponic culture unit 6. And consist of

建屋2は、入出口、通気用の開口等を備え、養殖部3を覆うように設置され、養殖する水生生物の種類に応じて設ける。鳥から水生生物を保護するとともに、直射日光の照射量を調節する。例えば、ビニールハウスの上部に、網目状の遮光ネット(採光量調節ネット)で覆うなどすればよい。完全に遮光してしまうと、当然植物は育たない。   The building 2 includes an entrance / exit, an opening for ventilation, and the like, is installed so as to cover the culture section 3, and is provided according to the type of aquatic organism to be cultivated. Protect aquatic organisms from birds and adjust the amount of direct sunlight. For example, the upper part of the greenhouse may be covered with a net-like shading net (light quantity adjustment net). Naturally, plants will not grow if they are completely shaded.

養殖部3は、ここでは、底部に取水部3iを設けた大きさの異なる3区画の第一水槽3a、第二水槽3b、第三水槽3cと、必要に応じて各水槽内部に敷かれ水槽の縁に留め具3fで固定されたビニルシート3eと、水槽上部に渡された渡棒6iと、渡棒6iに固定した足場6kを備える。ビニルシート3e上に養殖用の水3dが溜められ、その水で魚3gなどの水生生物を飼育、養殖する。   Here, the aquaculture unit 3 includes three sections of a first water tank 3a, a second water tank 3b, and a third water tank 3c, each having a water intake section 3i at the bottom, and a water tank that is laid inside each water tank as necessary. A vinyl sheet 3e fixed to the edge of the container with a fastener 3f, a crossing bar 6i passed to the upper part of the water tank, and a scaffold 6k fixed to the crossing bar 6i. Aquaculture water 3d is stored on the vinyl sheet 3e, and aquatic organisms such as fish 3g are bred and cultured with the water.

各水槽は、コンクリート製などが採用でき、底部には水槽の大きさに応じて適当数の鉢状に窪ませた取水部3iを設ける。ビニルシート3eは、水生生物が水槽に擦れて、傷付くのを防ぐ。足場6kは、水耕栽培部6での作業を容易にするために設けてある。水槽には、水生生物に応じて、水3dに酸素、空気を供給するエアレーション6mラインが設けられる。   Each water tank can be made of concrete or the like, and the bottom is provided with a water intake section 3i that is recessed into an appropriate number of bowls according to the size of the water tank. The vinyl sheet 3e prevents aquatic organisms from rubbing against the water tank and being damaged. The scaffold 6k is provided to facilitate the work in the hydroponic cultivation unit 6. The aquarium is provided with an aeration 6m line for supplying oxygen and air to the water 3d according to aquatic organisms.

送水部4は、水槽の水を浄化部5に送水する装置であって、水槽底部の取水部3iに連結する土9aに埋まった送水パイプ4aと、送水パイプ4aから送られた水を受ける桝4bと、桝4b内の水を浄化部5に送水するポンプ4cと、ポンプ4cによって送水された水を流す往路パイプ4eとからなる。送水パイプ4aは、組み立てやすいように、フランジ4hを含む水槽側端部を分割し、嵌着するようにするとよい。   The water supply unit 4 is a device for supplying water from the water tank to the purification unit 5 and receives a water supply pipe 4a buried in the soil 9a connected to the water intake unit 3i at the bottom of the water tank and water sent from the water supply pipe 4a. 4b, a pump 4c for feeding the water in the tub 4b to the purification unit 5, and an outward pipe 4e for feeding the water fed by the pump 4c. The water supply pipe 4a is preferably divided and fitted to the water tank side end including the flange 4h so as to be easily assembled.

次に、図3を参照して、取水部3iの穴3kと送水部4の連結を説明する。取水部3iの底の穴3kに送水部4の末端の送水パイプ4aのフランジ4hを係止し、その上に穴3kに相当する穴を設けたビニルシート3eを載せ、さらに押さえ4nでビニルシート3eを挟み、押さえ4nと共にフランジ4hをボルト4k及びナット4mで水槽底部に固定する。これにより、ビニルシート3eは、フランジ4hと押さえ4nの間に挟持される。取水部3iの大きさは直径50−100cm程度あるとよい。   Next, with reference to FIG. 3, the connection of the hole 3k of the water intake part 3i and the water supply part 4 is demonstrated. The flange 4h of the water supply pipe 4a at the end of the water supply section 4 is locked in the hole 3k at the bottom of the water intake section 3i, and a vinyl sheet 3e provided with a hole corresponding to the hole 3k is placed on the flange 4h. 3e is sandwiched, and the flange 4h together with the presser 4n is fixed to the bottom of the water tank with bolts 4k and nuts 4m. Thereby, the vinyl sheet 3e is clamped between the flange 4h and the presser 4n. The size of the water intake section 3i is preferably about 50-100 cm in diameter.

そして、送水パイプ4aの取水口4gに、目皿4iを設置する。目皿4iは、網目状のプレートで、食べ残しの餌、糞を通すが、水生生物を通さない目開きのものを用いる。目皿4iは、ネジで取水口4gの送水パイプ4aに固定してもよいし、螺着してもよい。   And the eye plate 4i is installed in the water intake 4g of the water supply pipe 4a. The mesh plate 4i is a mesh-like plate, which uses uneaten bait and feces, but has an opening that does not pass aquatic organisms. The eye plate 4i may be fixed to the water supply pipe 4a of the water intake 4g with a screw, or may be screwed.

フランジ4hの周囲に、段差が生じた場合には、水生生物の餌の食べ残し、糞が溜まらないように、コーティング剤4pでコーティングするとよい。コーティングすることで、また、水槽の水3dの漏洩が防止できる。   If there is a step around the flange 4h, it may be coated with the coating agent 4p so that the aquatic organisms are left uneaten and dung is not collected. By coating, leakage of water 3d in the aquarium can be prevented.

図2に示すように、水槽と桝4bとは送水パイプ4aで連結されているため、ポンプ4cで桝4b内の水を浄化部5に送水することで、桝4bの水位4dが低下する。すると水槽の水位3hは桝4bの水位4dと同じ高さになるように、自然と水槽の水3dは桝4b内に流れ込む(点線矢印)。即ち、原理的には、ポンプ4cで送水した量の水が水槽に戻されることとなる。   As shown in FIG. 2, since the water tank and the trough 4b are connected by a water feeding pipe 4a, the water level 4d of the trough 4b is lowered by feeding the water in the trough 4b to the purification unit 5 by the pump 4c. Then, the water 3d in the tank naturally flows into the tank 4b so that the water level 3h in the tank is at the same height as the water level 4d of the tank 4b (dotted arrow). That is, in principle, the amount of water sent by the pump 4c is returned to the water tank.

桝4b内の水位4dは、水槽の水位3hと同じになるので、そのときの桝4bの水位に応じて、飛散、蒸散、排水した水量に相当する水を水系に補給すればよい。桝4b内の水位4dは、エアレーションなどの攪乱要因がないので、他の場所の水位より安定している。したがって、桝4b内の水位を感知するセンサーを設け、桝4b内の水位4dに応じて水の循環系に、自動かつ安定的に給水することができる。   Since the water level 4d in the tub 4b is the same as the water level 3h of the water tank, the water system may be replenished with water corresponding to the amount of scattered, transpirated and drained water according to the water level of the tub 4b at that time. The water level 4d in the ridge 4b is more stable than the water level in other places because there is no disturbance factor such as aeration. Therefore, a sensor for sensing the water level in the tub 4b can be provided, and water can be automatically and stably supplied to the water circulation system according to the water level 4d in the tub 4b.

このように、水槽底部の擂り鉢状の取水部3iと、桝4bを設けることで、さらに水生生物が魚であれば、魚が水槽底部を泳ぐことで、餌の食べ残し、糞を取水口4g集め、送水パイプ4a、送水部4を経由して浄化部5に送られることとなる。その結果、食べ残し、糞に起因する水槽内の水3dを廃棄しての水槽内の清掃回数を減らすことができ、さらには必要としなくなる。   Thus, by providing the bowl-shaped water intake 3i at the bottom of the aquarium and the salmon 4b, if the aquatic organism is a fish, the fish swims in the bottom of the aquarium, so that the food remains uneaten and the dung is removed. 4 g is collected and sent to the purification unit 5 via the water supply pipe 4 a and the water supply unit 4. As a result, it is possible to reduce the number of cleanings in the aquarium by discarding the water 3d in the aquarium due to uneaten and feces, and further, it is not necessary.

浄化部5は、ここでは、送水部4と接続する第一浄化槽5a、連結管5sをそれぞれ介して第一浄化槽5aに続く、第二浄化槽5b、第三浄化槽5c、さらに養殖部3に浄化水を戻す還路パイプ6e(水耕栽培部6)に接続する第四浄化槽5dを、2列並列に備えてなる。図1上段の浄化部5は第一水槽3aに、図1下段の浄化部5は、第二、第三水槽3b、3cに、浄化水を戻す。   Here, the purification unit 5 is connected to the first purification tank 5a via the first purification tank 5a and the connecting pipe 5s connected to the water supply unit 4, respectively, the second purification tank 5b, the third purification tank 5c, and further the purified water to the culture unit 3. The 4th septic tank 5d connected to the return pipe 6e (hydroponic cultivation part 6) which returns is provided in 2 rows in parallel. The upper purification unit 5 in FIG. 1 returns purified water to the first water tank 3a, and the lower purification unit 5 in FIG. 1 returns purified water to the second and third water tanks 3b and 3c.

そして、浄化部5の複数の浄化槽は、被処理水5wの流れの上流から下流に向け階段状に水位5uが低くなり、次の浄化槽へ自然落下で移送されるよう、地面9から高さの異なる台5gに載置され、多段式の滝のように構成される。勿論、台5gを用いることなく、地面9を階段状に造成して、台5gを用いたように水位5uに段差を設けてタンク5eを設置してもよい。   And the several septic tanks of the purification | cleaning part 5 have the height from the ground 9 so that the water level 5u may become stepwise toward the downstream from the upstream of the flow of the to-be-processed water 5w, and it may be transported by the natural fall to the next septic tank. It is placed on a different table 5g and configured like a multi-stage waterfall. Of course, without using the base 5g, the ground 9 may be formed in a staircase shape, and the tank 5e may be installed by providing a step at the water level 5u as with the base 5g.

図2、図4に示すように、第一浄化槽5aは、送水部4から送水された被処理水5wを貯留しつつ曝気5iするタンク5eと、タンク5eの口部5xに係止され底部にフィルタ5qを備える穴5pが穿設された容器5nと、穴5oが穿設されタンク5eの口部5xに螺着する蓋5fと、タンク5e底部にネットなどに小分けして詰められた微生物の菌床となる赤玉土5kと御影石5mと、第二浄化槽5bに連通する側に配置されたフィルタ5rと、第二浄化槽5bに被処理水5wを流す連結管5sと、からなる。   As shown in FIGS. 2 and 4, the first septic tank 5a has a tank 5e that stores the treated water 5w fed from the water feeding section 4 and aeration 5i, and is locked to the mouth 5x of the tank 5e. A container 5n having a hole 5p provided with a filter 5q, a lid 5f having a hole 5o and screwed into the mouth 5x of the tank 5e, and a microorganism packed in a net or the like at the bottom of the tank 5e. It consists of red bean clay 5k and granite 5m that serve as the fungus bed, a filter 5r disposed on the side communicating with the second septic tank 5b, and a connecting pipe 5s for flowing the treated water 5w through the second septic tank 5b.

さらに、浄化部5には、浄化部5の各タンク5eの側面底部には、タンク5e内の排水、タンク5e底部に溜まった汚泥5aaを個別に排出することができる配管5y及びその開閉を制御するバルブ5zが設けられ、配管5yはそれぞれ連結し、一箇所に汚泥を収集することができるようにしてある。   Further, the purifying unit 5 controls the piping 5y capable of individually discharging the drainage in the tank 5e and the sludge 5aa accumulated in the bottom of the tank 5e at the bottom of the side surface of each tank 5e of the purifying unit 5 and the opening and closing thereof. A valve 5z is provided, and the pipes 5y are connected to each other so that sludge can be collected at one place.

図4に示すように、蓋5fの穴5oに往路パイプ4eが挿通し、被処理水5wをポンプ4cによって、第一浄化槽5aに連続送水する。容器5nを設けることで、フィルタ5rの洗浄回収を減らし、メンテナンス作業が用になるとともに、フィルタ5qの洗浄を容易にする。また、容器5n側面に穴5pを設けることで、藻などが急速に増殖しフィルタ5qが目詰まりしたときでも、タンク5e外に、被処理水5wが漏出することを防ぐことができる。フィルタ5rは第一浄化槽5aにだけ設置すれば十分である。   As shown in FIG. 4, the forward pipe 4e is inserted into the hole 5o of the lid 5f, and the treated water 5w is continuously fed to the first septic tank 5a by the pump 4c. By providing the container 5n, the cleaning recovery of the filter 5r is reduced, the maintenance work is used, and the cleaning of the filter 5q is facilitated. Further, by providing the hole 5p on the side surface of the container 5n, it is possible to prevent the treated water 5w from leaking out of the tank 5e even when algae or the like rapidly grow and the filter 5q is clogged. It is sufficient to install the filter 5r only in the first septic tank 5a.

曝気5iは、コンプレッサ5hからチューブ5jを介してタンク5e内に空気を導入する。好気的条件で微生物による有機物の分解を促進させ、アンモニアを亜硝酸イオン、硝酸イオンへと硝化させ、植物に窒素源として吸収させやすくさせる。曝気5iは、他の水槽にも同様に導入される。   The aeration 5i introduces air into the tank 5e from the compressor 5h through the tube 5j. It promotes the decomposition of organic matter by microorganisms under aerobic conditions, nitrifies ammonia into nitrite ions and nitrate ions, and makes it easy for plants to absorb as a nitrogen source. The aeration 5i is similarly introduced into other water tanks.

赤玉土5kは、一般に関東ローム層の赤土を乾燥後、ふるいで粒の大きさごとに選別して作られ、園芸に用いられる。赤玉土5kは、微生物の菌床、濾過材である。ここでは、鉾田産を使用した。鉾田産は硬質で知られ、試験では、つぶれることなく、長期間粒の形状を保持した。   Akadama soil 5k is generally made by drying the red soil of the Kanto Loam layer and selecting it according to the size of the grains with a sieve, and is used for gardening. Akadama soil 5k is a microbial bed and filter material. Here, I used Iwata. Iwata is known for being hard, and in the test, it kept the shape of the grains for a long time without crushing.

御影石5mは、花崗岩のことであり、微生物の菌床、濾過材であるとともに、ミネラル供給減でもある。ここでは、笠間市稲田産の御影石の砂利を使用した。このように、赤玉土5k、御影石5mともに地産品を使用することで、地域振興に資する。赤玉土5k、御影石5mは、他の水槽にも同様に投入される。ネットなどに小分けして、使用することで、定期的なタンク5e内清掃において、それらも洗浄するときに、扱いやすい。   Granite 5m is granite, and it is a microbial fungus bed and filter material, and it also reduces mineral supply. Here, we used granite gravel from Inada, Kasama City. In this way, using local products for both Akadama 5k and granite 5m contributes to regional development. Akadama 5k and granite 5m are also introduced into other aquariums in the same way. By subdividing it into a net or the like, it is easy to handle when cleaning them in regular cleaning of the tank 5e.

連結管5sは、図2、4に示すように、上流側がタンク5e底部汚泥層の上の側面に連結し、上に起立し、第二浄化槽5b内に挿通し、被処理水5wを水位5u差により、第二浄化槽5bに流す。連結管5sの上方は開口し、左右が開口し断面T字状の空気抜き5tが上部に嵌る。連結管5sの直上を開口しないことで、タンク5e間の縁を切り、真上からの有害物質の被処理水5wへの混入を防止する。有害物質として、田畑に散布される農薬などが例示される。   As shown in FIGS. 2 and 4, the connecting pipe 5s is connected to the upper surface of the tank 5e bottom sludge layer on the upstream side, stands up, is inserted into the second septic tank 5b, and the treated water 5w passes through the water level 5u. Due to the difference, it flows into the second septic tank 5b. The upper part of the connecting pipe 5s is opened, the left and right are opened, and an air vent 5t having a T-shaped cross section is fitted into the upper part. By not opening the upper part of the connecting pipe 5s, the edge between the tanks 5e is cut to prevent the harmful substances from entering the treated water 5w from directly above. Examples of harmful substances include agricultural chemicals sprayed on fields.

第二浄化槽5bは、図2に示すように、第一浄化槽5aから送水された被処理水5wを貯留しつつ曝気5iするタンク5eと、タンク5eの口部5xに螺着する蓋5f(穴5oなし)と、タンク5e底部にネットなどに小分けして詰められた微生物の菌床となる赤玉土5kと御影石5mと、第三浄化槽5cに被処理水5wを流す連結管5sと、からなる。第三、第四浄化槽5c、5dの構成は、第二浄化槽5bと同じである。ただし、第四浄化槽5dは、還路パイプ6eに接続する。浄化部5は、養殖部3の水3dの容積の1/3程度とすることが望ましいため、複数のタンク5eを用いた。   As shown in FIG. 2, the second septic tank 5b includes a tank 5e for storing the treated water 5w fed from the first septic tank 5a and aeration 5i, and a lid 5f (hole) screwed to the mouth 5x of the tank 5e. 5o), red bead 5k and granite 5m serving as a microbial bed packed in a net or the like at the bottom of the tank 5e, and a connecting pipe 5s for flowing the treated water 5w into the third septic tank 5c. . The configuration of the third and fourth septic tanks 5c and 5d is the same as that of the second septic tank 5b. However, the fourth septic tank 5d is connected to the return pipe 6e. Since it is desirable that the purification unit 5 be about 1 / of the volume of the water 3d of the culture unit 3, a plurality of tanks 5e are used.

このような浄化槽を備えことで、内部に赤虫、淡水性の貝などの水生小動物が自生、飼育することができ、自然環境が構築され、一層有機物の分解が促進されるとともに、浄化槽内に生息する水生小動物が、自然落下による被処理水5wの流れで移送されることで、還路パイプ6eを通り、水槽に流れていき、養殖魚のエサにもなり得る。   By providing such a septic tank, aquatic small animals such as red caterpillars and freshwater shellfish can grow and grow inside, a natural environment is built, further decomposition of organic matter is promoted, and in the septic tank Inhabited aquatic small animals are transported by the flow of the water to be treated 5w due to natural fall, so that they pass through the return pipe 6e and flow into the aquarium and can be used as food for cultured fish.

水生小動物の自生は、チョウザメの養殖に最適である。貝としては、サカマキガイが例示できる。当該養殖システムでは、チョウザメは貝を餌にし、排泄し、浄化部5で貝が排泄物を有機体窒素に分解し、増殖する食物サイクルが形成される。また、過剰に増殖したサカマキガイは、採取して、鶏の餌などに使用できる。   Aquatic small animals are ideal for sturgeon farming. An example of the shellfish is Sakamakigai. In the aquaculture system, the sturgeon feeds and excretes the shellfish, and the purifier 5 decomposes the waste into organic nitrogen to form a food cycle in which it grows. The excessively grown scallop can be collected and used as chicken food.

水耕栽培部6は、図1、2に示すように、還路パイプ6eは、第四浄化槽5dの側面に連絡し、水位5u差によって流れ出した曝気処理された水を養殖部3の水槽に端部から放水6hして戻す。次に、図5を参照して、還路パイプ6eの敷設方法を説明する。   As shown in FIGS. 1 and 2, the hydroponic cultivation unit 6 connects the return pipe 6 e to the side surface of the fourth septic tank 5 d, and supplies the aerated water that has flowed out due to the difference in the water level 5 u to the aquarium of the culture unit 3. Water is discharged from the end for 6 hours and returned. Next, a method for laying the return pipe 6e will be described with reference to FIG.

還路パイプ6eは、上面に穴6fが穿設された直長パイプ6a、直短パイプ6b、90°に屈曲したエルボーパイプ6d、水の流れを分ける分岐パイプ6cを連結して、水槽上部に配置し、水耕栽培部6となす。長さの異なるパイプ、各パイプの連結の組み合わせ工夫することで、水槽の大きさ等に応じて、種々の形状の敷設を可能にする。還路パイプ6eの穴6fに水耕栽培用のポット7を嵌めて水耕栽培をする。   The return pipe 6e includes a straight pipe 6a having a hole 6f formed on the upper surface, a straight pipe 6b, an elbow pipe 6d bent at 90 °, and a branch pipe 6c that separates the flow of water. It arranges and becomes hydroponics part 6. By devising a combination of pipes having different lengths and connecting the pipes, various shapes can be laid according to the size of the aquarium. Hydroponics is carried out by fitting a pot 7 for hydroponics into the hole 6f of the return pipe 6e.

還路パイプ6eを水槽の上部に折返し複数列配置(蛇行)することで、水耕栽培部6の設置場所を水槽と別に確保する必要がなく、コンパクトな水耕栽培を可能にする。また、パイプ上部に穴6fを穿設して水耕栽培部6とすることで、施工費を低く抑え、かつ施工期間を短くすることができるとともに、配置変更、拡縮も容易になる。   By arranging the return pipes 6e in a plurality of rows (meandering) at the upper part of the water tank, it is not necessary to secure the installation location of the hydroponics section 6 separately from the water tank, thereby enabling compact hydroponics. Moreover, by making the hole 6f in the upper part of the pipe to form the hydroponic cultivation unit 6, the construction cost can be kept low and the construction period can be shortened, and the arrangement change and expansion / contraction can be facilitated.

さらに還路パイプ6eを透明な塩化ビニル管などを用いれば、水の汚れを容易に目視することができる。加えて、水槽の上部に還路パイプ6eを設置すれば、還路パイプ6eの穴6fから水が溢れても、水槽に落ちるだけであるので、養殖水の減少の心配はない。   Further, if the return pipe 6e is made of a transparent vinyl chloride pipe or the like, water stains can be easily observed. In addition, if the return pipe 6e is installed in the upper part of the aquarium, even if water overflows from the hole 6f of the return pipe 6e, it only falls into the aquarium, so there is no fear of a decrease in the aquaculture water.

還路パイプ6eは、水平に敷設しても水位5uに応じて自然に曝気処理水を水槽まで移送することができるが、後述のように、還路パイプ6eは植物栽培用のポット7が嵌められるため、還路パイプ6eの端部に向けやや傾斜させて敷設するとよい。   Even if the return pipe 6e is laid horizontally, the aeration treated water can be naturally transferred to the aquarium according to the water level 5u. However, as will be described later, the return pipe 6e is fitted with a pot 7 for plant cultivation. Therefore, it is good to lay it incline slightly toward the end of the return pipe 6e.

次に、水耕栽培用のポット7を穴6fに嵌めて水耕栽培をする状況について図6を参照して詳しく説明する。図6は、還路パイプ6eの縦断面図模式図である。   Next, a situation where hydroponics pot 7 for hydroponics is fitted into hole 6f and hydroponics is performed will be described in detail with reference to FIG. FIG. 6 is a schematic longitudinal sectional view of the return pipe 6e.

還路パイプ6eは、図6(A)に示すように、上面に穴6fが穿設され、内部に処理水6gが流れる。図6(B)に示すように、還路パイプ6eの穴6fに植物栽培用のポット7を嵌め植物8を水耕栽培する。   As shown in FIG. 6A, the return pipe 6e has a hole 6f formed in the upper surface, and the treated water 6g flows inside. As shown in FIG. 6B, the plant cultivation pot 7 is fitted into the hole 6f of the return pipe 6e, and the plant 8 is hydroponically cultivated.

ポット7は、培養土7bが内部に詰められ、側面及び底面には貫通孔7aが穿設されている。培養土7bとしては、バーミキュライトとが好適である。貫通孔7aから植物8の根8aが還路パイプ6e内張りだし、養分を吸収する。還路パイプ6e内では、曝気処理水6gの流れが形成され、根8aと次々と接触するため、水の流れの少ない栽培床である水槽での水耕栽培に比べ、植物8の水槽へのドブ漬けに比べ、水耕栽培部6での植物8の窒素源の吸収率は極めて高い。   The pot 7 is filled with culture soil 7b and has through holes 7a on the side and bottom. Vermiculite is suitable as the culture soil 7b. The root 8a of the plant 8 begins to line the return pipe 6e from the through hole 7a and absorbs the nutrients. In the return pipe 6e, a flow of the aerated treated water 6g is formed and comes into contact with the roots 8a one after another. Therefore, compared with hydroponics in a tank that is a cultivation floor with little water flow, The absorption rate of the nitrogen source of the plant 8 in the hydroponic cultivation unit 6 is extremely high compared to the dove pickling.

また、図6(B)に示すように、還路パイプ6eに穴を穿設し、ポット7を嵌める方式の水耕栽培部6とすることで、植物の種類、又は/及び植物の生育時期に応じて、植物栽培用のポット7を挿入する穴6fの位置を容易に変更することができ、栽培植物に適した窒素濃度、日当たりを容易に調節することができる。還路パイプ6e上流では、窒素源濃度が高く、植物8の根8aと接触を繰り返した下流部では窒素源濃度が低い。窒素源濃度差を利用して、水耕栽培植物を選択することもできる。   Moreover, as shown to FIG. 6 (B), by making a hole in the return pipe 6e, and setting it as the hydroponics part 6 of the system which fits the pot 7, the kind of plant or / and the growth time of a plant Accordingly, the position of the hole 6f for inserting the pot 7 for plant cultivation can be easily changed, and the nitrogen concentration and sunlight suitable for the cultivated plant can be easily adjusted. In the upstream of the return pipe 6e, the nitrogen source concentration is high, and in the downstream portion where contact with the root 8a of the plant 8 is repeated, the nitrogen source concentration is low. Hydroponics plants can also be selected using the nitrogen source concentration difference.

他方、図1の第一水槽3aに示すように、建屋2の外に還路パイプ6eを敷設することで、一層日当たりのより環境で水耕栽培することもできる。   On the other hand, as shown in the first water tank 3a of FIG. 1, by laying the return pipe 6e outside the building 2, hydroponic cultivation can be performed in a more sunny environment.

なお、当該水耕栽培では、一般に水耕栽培に使用できる野菜類が栽培可能であるが、特に、ハーブ類、クレソン、セリ、バジル、ミント、シソなどが良く育つ。またレタス類の生育も良好であった。還路パイプ6e内の流水の上流側の窒素源濃度が高く、内部に空洞が形成される野菜の栽培に適している。例えば、シシトウ、ピーマン、タカノツメなどである。   In the hydroponics, vegetables that can be generally used for hydroponics can be cultivated. In particular, herbs, watercress, seri, basil, mint, perilla, etc. grow well. The growth of lettuce was also good. The nitrogen source concentration on the upstream side of running water in the return pipe 6e is high, and it is suitable for cultivation of vegetables in which a cavity is formed. For example, Shishito, green pepper, Takatsutsume, etc.

これにより、養殖用の水から硝化された窒素源を根8aから吸収し、水の浄化を補助する。そうすることで、養殖用の水3dを循環再利用することができ、水3dの節水、さらに、清掃、水の入れ換え作業を軽減することができる。   Thereby, the nitrogen source nitrified from the aquaculture water is absorbed from the roots 8a, and the purification of the water is assisted. By doing so, the aquaculture water 3d can be circulated and reused, and the water saving of the water 3d, and further cleaning and water replacement operations can be reduced.

具体的には、2.5×15×0.5≒19(m)の水槽(第一水槽3a)に、チョウザメ約500匹(1歳魚)を飼育した本年7月中旬からの1月の養殖試験では、水槽の水3dの交換は1度も行わなかったが、チョウザメは1匹も死亡しなかった。本発明導入前における単純曝気浄水処理においては、夏場では月3回の水の交換が必要であったことからすると、本発明の節水効果、水の入れ換え作業の軽減効果は極めて大きい。 Specifically, about 500 sturgeon (1 year old fish) were raised in the middle of July this year in a water tank (first tank 3a) of 2.5 × 15 × 0.5≈19 (m 3 ). In the aquaculture test of the moon, the water tank 3d was never changed, but no sturgeon died. In simple aerated water purification treatment prior to the introduction of the present invention, it was necessary to change the water three times a month in the summer, so that the water-saving effect of the present invention and the effect of reducing water replacement work are extremely large.

なお、水耕栽培を備える水生生物の養殖システムにおいて、給水、排水経路は省略したが、どのブロックから給水、排水してもよい。給水は、水槽に井戸水を給水することが経済的かつ簡易である。排水は、各ブロックから可能にすることが清掃の観点から望ましい。また、各ライン(パイプ)等には、バルブが設けられ、水の流量を調節することができる。   In the aquatic aquaculture system equipped with hydroponics, water supply and drainage paths are omitted, but water supply and drainage may be performed from any block. It is economical and simple to supply well water to the water tank. It is desirable from the viewpoint of cleaning that drainage is possible from each block. Each line (pipe) or the like is provided with a valve so that the flow rate of water can be adjusted.
