これより、本発明の実施形態について、図面を参照しながら説明する。
図１に、本発明の第１実施形態の水質浄化装置１を示す。水質浄化装置１は、マイクロナノバブル発生槽２と、植物栽培槽３とを有し、例えば池４の水を浄化する装置である。 Embodiments of the present invention will now be described with reference to the drawings.
In FIG. 1, the water purification apparatus 1 of 1st Embodiment of this invention is shown. The water purification device 1 has a micro / nano bubble generation tank 2 and a plant cultivation tank 3, and is an apparatus that purifies water in a pond 4, for example.

水質浄化装置１は、池４から浄化すべき原水を原水ポンプ５で汲み出して、マイクロナノバブル発生槽２に導入するようになっている。マイクロナノバブル発生槽２は、原水が補給される処理水を貯留し、水中ポンプ型マイクロナノバブル発生器６と、旋回流型マイクロナノバブル発生装置７とを備える。   The water purification device 1 draws raw water to be purified from the pond 4 with the raw water pump 5 and introduces it into the micro / nano bubble generation tank 2. The micro / nano bubble generation tank 2 stores treated water to which raw water is replenished, and includes an underwater pump type micro / nano bubble generator 6 and a swirling flow type micro / nano bubble generator 7.

水中ポンプ型マイクロナノバブル発生装置６は、ブロワ８から空気が供給され、吸い込んだ処理水を回転撹拌して供給された空気を分散させることでマイクロナノバブルを生成するものである。水中ポンプ型マイクロナノバブル発生装置６は、例えば、処理水中に毎分５リットルの空気を導入してマイクロナノバブルとする能力があるが、形成されるマイクロナノバブルがやや大きめになる特性がある。   The submersible pump type micro / nano bubble generating device 6 generates micro / nano bubbles by supplying air from the blower 8 and dispersing the supplied air by rotating and agitating the sucked treated water. The submersible pump type micro / nano bubble generator 6 has the capability of introducing 5 liters of air per minute into the treated water to form micro / nano bubbles, but has a characteristic that the formed micro / nano bubbles are slightly larger.

旋回流型マイクロナノバブル発生装置７は、マイクロナノバブル発生槽２の処理水を循環ポンプ９で吸い出して、旋回流型マイクロナノバブル発生器１０に導入し、旋回流型マイクロナノバブル発生器１０内における水流によって調節弁１１を介して空気を自給し、空気を剪断することでマイクロナノバブルを発生することができる。旋回流型マイクロナノバブル発生装置７は、例えば、毎分１リットルの空気をマイクロナノバブルとして処理水中に導入する能力があり、水中ポンプ型マイクロナノバブル発生器６に比して微細なマイクロナノバブルを発生させることができる。   The swirling flow type micro / nano bubble generating device 7 sucks out the treated water of the micro / nano bubble generating tank 2 with a circulation pump 9 and introduces it into the swirling flow type micro / nano bubble generator 10. Micro-nano bubbles can be generated by self-supplying air through the control valve 11 and shearing the air. The swirling flow type micro / nano bubble generator 7 has, for example, the ability to introduce 1 liter of air per minute into the treated water as micro / nano bubbles, and generates fine micro / nano bubbles as compared with the submerged pump type micro / nano bubble generator 6. be able to.

マイクロナノバブル導入槽２からオーバーフローした処理水は、オーバーフロー流路１２を介して、植物栽培槽３に導入される。   The treated water overflowed from the micro / nano bubble introduction tank 2 is introduced into the plant cultivation tank 3 via the overflow channel 12.

植物栽培槽３は、処理水が一定方向に流れる人工水路である。植物栽培槽３には、例えば川しょうぶ等の水草１３が根付くことが可能な定植床１４を形成する植物栽培容器１５が配設されている。   The plant cultivation tank 3 is an artificial water channel in which treated water flows in a certain direction. The plant cultivation tank 3 is provided with a plant cultivation container 15 that forms a fixed planting floor 14 in which aquatic plants 13 such as river ginger can take root.

植物栽培容器１５は、例えば、図２に示すように、側壁に魚が出入りできるように穴１６を開けた例えばＦＲＰ製の容器であり、その中程に多孔板１７を架設し、多孔板１７の上に礫（小石）等を敷き詰めることで、定植床１４を形成するとともに、定植床１４の下側に空間を形成している。植物栽培槽３において、植物栽培容器１５は、定植床１４が水没して水草１３が根付くことができるように配置される。   For example, as shown in FIG. 2, the plant cultivation container 15 is a container made of, for example, FRP in which a hole 16 is formed so that fish can enter and exit from the side wall. A fixed planting floor 14 is formed by spreading gravel (pebbles) or the like on the top, and a space is formed below the fixed planting floor 14. In the plant cultivation tank 3, the plant cultivation container 15 is arranged so that the fixed planting floor 14 can be submerged and the aquatic plants 13 can be rooted.

多孔板１７は、パンチングメタルやワイヤメッシュなどからなり、水草１３は、その根１３ａが多孔板１７を貫通して下側空間に延伸することができるようになっている。   The perforated plate 17 is made of a punching metal, a wire mesh, or the like, and the aquatic plants 13 have roots 13a that can penetrate the perforated plate 17 and extend into the lower space.

定植床１４の下部空間は、外部から隔離されており、魚類、甲殻類および貝類の住み処に適するように形成されている。よって、定植床１４を架設する高さや、穴１６の大きさ等は、住まわせる魚類等の種類に応じて設定することができる。   The lower space of the fixed planting floor 14 is isolated from the outside, and is formed so as to be suitable for fish, shellfish and shellfish. Therefore, the height at which the fixed planting floor 14 is constructed, the size of the hole 16, and the like can be set according to the type of fish to be inhabited.

図１に戻ると、植物栽培槽３からオーバーフローした処理水は、環流路１９を介して池４に返送されるようになっている。また、循環ポンプ９の吐出側を分岐した洗浄配管２０，２１は、原水ポンプ５の吐出配管や環流路１９を洗浄する際にのみ使用される。   Returning to FIG. 1, the treated water overflowed from the plant cultivation tank 3 is returned to the pond 4 via the annular flow path 19. Further, the cleaning pipes 20 and 21 branched from the discharge side of the circulation pump 9 are used only when cleaning the discharge pipe and the circular flow path 19 of the raw water pump 5.

続いて、本実施形態の水質浄化装置１の作用について説明する。
池４の藻類等を含む原水は、マイクロナノバブル発生槽２に汲み上げられ、マイクロナノバブルが導入される。 Then, the effect | action of the water purification apparatus 1 of this embodiment is demonstrated.
The raw water containing algae and the like in the pond 4 is pumped into the micro / nano bubble generation tank 2 and the micro / nano bubbles are introduced.

マイクロナノバブル発生槽２は、ポンプ型マイクロナノバブル発生装置６によって処理水中に大きめのマイクロナノバブルを発生させる。このマイクロナノバブルを含む処理水が、旋回型マイクロナノバブル発生装置７に取り込まれると、ポンプ型マイクロナノバブル発生装置６によって発生した大きめのマイクロナノバブルがさらに剪断され、より小さいマイクロナノバブルになる。つまり、旋回型マイクロナノバブル発生装置７は、空気量１Ｌ／分の微細なマイクロナノバブルを処理水中に発生させるだけでなく、ポンプ型マイクロナノバブル発生装置６が形成した大きめのマイクロナノバブルを剪断してより多くの、且つ、より微細なマイクロナノバブルを形成するのである。   The micro / nano bubble generation tank 2 generates large micro / nano bubbles in the treated water by the pump type micro / nano bubble generator 6. When the treated water containing the micro-nano bubbles is taken into the swivel type micro-nano bubble generator 7, the larger micro-nano bubbles generated by the pump type micro-nano bubble generator 6 are further sheared into smaller micro-nano bubbles. That is, the swivel type micro / nano bubble generator 7 not only generates fine micro / nano bubbles in the treated water but also shears large micro / nano bubbles formed by the pump type micro / nano bubble generator 6. Many and finer micro-nano bubbles are formed.

このように、大径大容量のマイクロナノバブル発生装置７と小径小容量のマイクロナノバブル発生装置７を併用することで、微細なマイクロナノバブルを効率よく大量に生成することができる。   Thus, by using the large-diameter large-capacity micro-nano bubble generator 7 and the small-diameter small-capacity micro-nano bubble generator 7 together, it is possible to efficiently generate a large number of fine micro-nano bubbles.

小容量の微細なマイクロナノバブルを発生するものとして、旋回型マイクロナノバブル発生装置７に代えて、加圧溶解ポンプ型マイクロナノバブル発生機、コンプレッサー型加圧型マイクロナノバブル発生機またはノズル噴射型マイクロナノバブル発生機が適用できる。また、大径大容量のマイクロナノバブル発生装置７および小径小容量のマイクロナノバブル発生装置７は、それぞれ、複数設けてもよく、３種類以上のマイクロナノバブル発生装置を設置してもよい。   In order to generate small micro-nano bubbles with a small capacity, instead of the swivel type micro-nano bubble generator 7, a pressurized dissolution pump type micro-nano bubble generator, a compressor type pressurized micro-nano bubble generator or a nozzle injection type micro-nano bubble generator Is applicable. Also, a plurality of large-diameter large-capacity micro-nano bubble generators 7 and small-diameter small-capacity micro-nano bubble generators 7 may be provided, or three or more types of micro-nano bubble generators may be provided.

マイクロナノバブル発生槽２において、マイクロナノバブルは、処理水中の好気性微生物を活性化し、処理水中の藻類やアンモニア性窒素を硝酸性窒素に分解する。   In the micro / nano bubble generation tank 2, the micro / nano bubbles activate aerobic microorganisms in the treated water, and decompose alga and ammonia nitrogen in the treated water into nitrate nitrogen.

藻類やアンモニア性窒素が分解されて生じる硝酸性窒素を含む処理水は、オーバーフロー流路１２を介して植物栽培槽３に導入される。   Treated water containing nitrate nitrogen produced by the decomposition of algae and ammonia nitrogen is introduced into the plant cultivation tank 3 via the overflow channel 12.

植物栽培槽３では、水草１３が、光合成を行うために、処理水中の硝酸性窒素を養分として、その根から吸収する。つまり、処理水中の硝酸性窒素は、水草に吸収されて水草の組織中に固定される。   In the plant cultivation tank 3, the aquatic plants 13 absorb nitrate nitrogen in the treated water as nutrients for photosynthesis. That is, nitrate nitrogen in the treated water is absorbed by the aquatic plants and fixed in the aquatic tissue.

定植床１４の下側空間に住む魚等は、水草１３の表面に付着した藻類やその死骸、および、成長しすぎた水草１３を食べて成長する。このため、水草１３は、常に、適切に日光を浴びることができ、効率よく光合成を行うことができる状態に維持される。   Fishes and the like that live in the lower space of the fixed planting floor 14 grow by eating algae attached to the surface of the aquatic plants 13, dead bodies thereof, and overgrown aquatic plants 13. For this reason, the aquatic plants 13 are always maintained in a state where they can be properly exposed to sunlight and can efficiently perform photosynthesis.

水草によって硝酸性窒素を吸収除去した処理水は、藻類が発生し難く、植物栽培槽３からオーバーフローした処理水を環流路１９を介して池４に環流することで、池４における藻類の発生を低減することができる。つまり、池４の水を水質浄化装置１に繰り返して循環させることで、その透明度を高めることができる。   Treated water from which nitrate nitrogen has been absorbed and removed by aquatic plants is unlikely to generate algae. Can be reduced. That is, the transparency of the pond 4 can be increased by repeatedly circulating the water in the water purification device 1.

また、池４の原水が、例えば湧き水であって比較的清浄度が高い場合、植物栽培槽３において、例えばわさび等の食用の水草１３を栽培することもできる。特に、水質浄化装置１でわさびを栽培すると、墨入り病の発生を抑え、品質のよいわさびを生産することができる。   Further, when the raw water of the pond 4 is, for example, spring water and is relatively clean, edible aquatic plants 13 such as wasabi can be cultivated in the plant cultivation tank 3. In particular, when wasabi is cultivated with the water purification device 1, it is possible to suppress the occurrence of inked diseases and produce high quality wasabi.

また、池４の原水が、例えば湧き水等である場合、定植床１４の下側空間で、例えばマス等の冷水魚のような食用魚を養殖することもできる。水質浄化装置１によって、水質が良好に維持されるので、冷水魚はストレスなく成長する。   When the raw water of the pond 4 is spring water, for example, edible fish such as cold water fish such as trout can be cultured in the lower space of the fixed planting floor 14. Since the water quality is well maintained by the water purification device 1, the cold water fish grows without stress.

図３に、本発明の第２実施形態の水質浄化装置１を示す。以降の説明において、先に説明した構成要素と同じ構成要素には、同じ符号を付して説明を省略する。   In FIG. 3, the water purification apparatus 1 of 2nd Embodiment of this invention is shown. In the following description, the same components as those described above are denoted by the same reference numerals, and description thereof is omitted.

本実施形態の水質浄化装置１のマイクロナノバブル発生槽２は、貯留している処理水に界面活性剤を一定量投入する界面活性剤投入装置２２を備えている。界面活性剤投入装置２２により投入する界面活性剤は、できるだけ微生物による分解が容易なものを使用することが好ましく、例えば、安価な家庭用の洗剤等を用いることができる。   The micro / nano bubble generation tank 2 of the water purification device 1 of the present embodiment includes a surfactant charging device 22 for charging a certain amount of a surfactant into the stored treated water. It is preferable to use a surfactant that can be easily decomposed by microorganisms as much as possible, for example, an inexpensive household detergent or the like.

マイクロナノバブル発生槽２の処理水に界面活性剤を投入することで、マイクロナノバブルの発生を容易にし、且つ、発生したマイクロナノバブルが長時間持続する。これによって、処理水中の好気性微生物を活性化して藻類等を分解させる効果が高くなる。   By introducing a surfactant into the treated water of the micro / nano bubble generation tank 2, the generation of micro / nano bubbles is facilitated, and the generated micro / nano bubbles last for a long time. This increases the effect of activating aerobic microorganisms in the treated water to decompose algae and the like.

よって、本実施形態の水質浄化装置１は、第１実施形態よりも、より富栄養化度が高い池などの水質浄化に適用できる。   Therefore, the water purification apparatus 1 of this embodiment can be applied to water purification such as a pond having a higher degree of eutrophication than the first embodiment.

図４に、本発明の第３実施形態の水質浄化装置１を示す。本実施形態では、マイクロナノバブル発生槽２からオーバーフローした処理水を、オーバーフロー流路１２ａを介して池４に環流させている。また、オゾン発生装置２４がポンプ型マイクロナノバブル発生装置６の吸気にオゾンを供給するようになっている。   In FIG. 4, the water purification apparatus 1 of 3rd Embodiment of this invention is shown. In the present embodiment, the treated water that has overflowed from the micro / nano bubble generating tank 2 is circulated to the pond 4 via the overflow channel 12a. The ozone generator 24 supplies ozone to the intake air of the pump type micro / nano bubble generator 6.

また、植物栽培槽３には、池４に設置したポンプ２５により、清浄化すべき原水が汲み上げられて供給されるようになっている。   The plant cultivation tank 3 is supplied with raw water to be purified by a pump 25 installed in the pond 4.

本実施形態では、ポンプ型マイクロナノバブル発生装置６により、マイクロナノバブル発生槽２に貯留している処理水中にオゾンマイクロナノバブルが導入される。オゾンマイクロナノバブルは、オゾンが有する強力な酸化力により、処理水中の藻類を枯らす作用を有する。   In the present embodiment, ozone micro / nano bubbles are introduced into the treated water stored in the micro / nano bubble generation tank 2 by the pump type micro / nano bubble generator 6. Ozone micro / nano bubbles have an action of withering algae in the treated water by the strong oxidizing power of ozone.

本実施形態では、オゾンマイクロナノバブルを含有する処理水を池４にオーバーフロー流路１２ａを介して環流させている。これは、オゾンマイクロナノバブルを含有する処理水を、植物栽培槽３に直接導入すると、オゾンの酸化力によって、植物３を枯らしたり、定植床１４の下側空間に住んでいる魚類等に悪影響を与えるからである。   In this embodiment, the treated water containing ozone micro-nano bubbles is circulated through the pond 4 via the overflow channel 12a. This is because, when treated water containing ozone micro-nano bubbles is directly introduced into the plant cultivation tank 3, the oxidative power of ozone will cause the plant 3 to wither or adversely affect fish and the like living in the lower space of the fixed planting floor 14. Because it gives.

本実施形態の水質浄化装置１は、特に、処理水中の藻類を枯らして除去する能力が高いので、第２実施形態よりも、さらに富栄養化度が高い場合、つまり、藻類が多く発生しているような場合に適用される。   The water purification apparatus 1 of the present embodiment has a particularly high ability to wither and remove algae in the treated water. Therefore, when the degree of eutrophication is higher than that of the second embodiment, that is, more algae are generated. Applicable in such cases.

オゾン発生装置２４は、図５に示す本発明の第４実施形態の水質浄化装置１のように、旋回型マイクロナノバブル発生装置７の吸気に接続してもよく、図６に示す本発明の第５実施形態の水質浄化装置１のように、ポンプ型マイクロナノバブル発生装置６および旋回型マイクロナノバブル発生装置７の両者の吸気に接続してもよい。   The ozone generator 24 may be connected to the intake air of the swirl type micro / nano bubble generator 7 like the water purification device 1 of the fourth embodiment of the present invention shown in FIG. 5, and the ozone generator 24 of the present invention shown in FIG. As in the water purification device 1 of the fifth embodiment, it may be connected to the intake air of both the pump type micro / nano bubble generator 6 and the swivel type micro / nano bubble generator 7.
