Description

本発明は、魚や鰻などを養殖する養殖場の汚れた飼育水を閉鎖循環式に処理する水処理装置に関する。 The present invention relates to a water treatment apparatus that treats dirty breeding water in a farm for culturing fish and carp in a closed circulation manner.

従来の養殖池は、養殖する魚、海老、鰻などに与えた餌の残餌や魚等の糞が水中の微生物によって処理されずに残って嫌気的環境の原因物質となるヘドロとなって、養殖池の底部に堆積する。そのため、空気中の酸素を水中に取り込み、水面に設置した水車を高速で回転させることにより、水面の水を大気中に放散させて大気中の酸素を取り込み、水中の溶存酸素(DO)値を一定値以上に維持する方法が一般的に行われている。 Conventional aquaculture ponds become sludge that becomes a causative substance of anaerobic environment by remaining unprocessed food by fish and shrimp, salmon, etc. Deposit at the bottom of the aquaculture pond. Therefore, oxygen in the air is taken into the water, and the water wheel installed on the surface of the water is rotated at a high speed to dissipate the water on the water surface to take in the oxygen in the air, and the dissolved oxygen (DO) value in the water is A method of maintaining a certain value or more is generally performed.

図5に示したように、従来の養殖池50の水面に設置した水車51は、モータ52を回転することにより羽根車53,53を高速で回転して、該養殖池の水面を掻き回して波立たせ、水面に円周方向に連続して波立部54,54を形成しながら、大気中の酸素を水中に取り込ませている。さらにまた、汚れた水を奇麗にするためには、養殖池50とは別に汚水を処理する処理槽55を必要とするため、設備投資費用が高くなるという欠点を有していた。 As shown in FIG. 5, the water wheel 51 installed on the water surface of the conventional aquaculture pond 50 rotates the impellers 53 and 53 at a high speed by rotating the motor 52 to stir the water surface of the aquaculture pond. Oxygen in the atmosphere is taken into the water while standing and forming the undulations 54 and 54 continuously in the circumferential direction on the water surface. Furthermore, in order to clean the dirty water, a treatment tank 55 for treating the dirty water is required in addition to the aquaculture pond 50, which has the disadvantage of increasing the capital investment cost.

水面攪拌用の水車53は、水面に対して垂直方向に高速回転しながら、水面部分の水を上方に掻き上げて空中に放散するため、モータは大きな力が要求され、その結果、モータ音や水を攪拌することによる大きな騒音を発生させると共に、消費電力量が多くなって極めて不経済であるという問題点を有していた。 Since the water wheel 53 for agitation of the water surface rotates at high speed in a direction perpendicular to the water surface, the water on the surface of the water is lifted upward and dissipated in the air, so that the motor is required to have a large force. In addition to the generation of large noise caused by stirring water, the amount of power consumption increases, which is extremely uneconomical.

養殖池の水中溶存酸素値を高めるための装置には、水面に設置した羽根車を回転して水を空中に拡散し、大気中の空気を水中に混入するものがある(特許文献1、参照)。さらに、羽根車を池の水面に沿って水平方向に回転させることにより、水面部分の酸素が多く含まれた水を池の中心から遠心方向に押し出し、この水が濾過材を通過する際に、水中に含まれる酸素を濾過材に付着している微生物に供給し、該微生物を活性化して水の汚れを分解するものがある(特許文献2、参照)。しかし、従来の水車は、池の表面部分に対流を起こすことはできても、池の底部に漂う酸素が不足した水を水面に上昇させることは困難であった。 As an apparatus for increasing the dissolved oxygen level in the aquaculture pond, there is an apparatus that rotates an impeller installed on the surface of the water to diffuse water into the air and mix air in the air (see Patent Document 1). ). Furthermore, by rotating the impeller horizontally along the water surface of the pond, water that contains a lot of oxygen on the water surface is pushed out from the center of the pond in the centrifugal direction, and when this water passes through the filter medium, There is one that supplies oxygen contained in water to microorganisms adhering to a filter medium, and activates the microorganisms to decompose water stains (see Patent Document 2). However, even though conventional water turbines can cause convection on the surface of the pond, it has been difficult to raise the water deficient in oxygen drifting at the bottom of the pond to the water surface.

さらに、養殖池の水面に設置した羽根車を水面に沿って回転させることにより、池の水面に水流を発生させ、他方、該羽根車が位置した下方の水底部にエアー噴出器を設置し、エアー源からのエアーを水中に噴出して水中に漂う好気性微生物に酸素供給して活性化すると共に、池中心の水底部に上向きの水流を発生させて水処理を行うものもある(特許文献3、参照)。しかし、微生物中の好気性微生物が、エアー噴出部の上方部分に常に集中しているとは限らず、また、エアーが届きにくいところに集まっていたりすると、前記微生物に酸素を供給することが困難であった。 Furthermore, by rotating an impeller installed on the water surface of the aquaculture pond along the water surface, a water flow is generated on the water surface of the pond, while an air blower is installed on the lower water bottom where the impeller is located, In addition to activating the aerobic microorganisms floating in the water by blowing air from the air source into the water and activating it, there are also water treatments that generate an upward water flow at the bottom of the pond center (patent document) 3, see). However, aerobic microorganisms in microorganisms are not always concentrated in the upper part of the air ejection part, and it is difficult to supply oxygen to the microorganisms if they are gathered in places where air is difficult to reach. Met.

飼育水の汚れは、太陽光を当てて光合成させたリ、紫外線によって微生物を殺菌したり、池内に設置した濾過材に付着させたりして、水中に浮遊する好気性微生物に酸素を含む新鮮な水を供給して好気性微生物を活性化することにより行っている。また、池の底部に堆積した有機物、一般にヘドロと呼ばれるものの分解には、バクテリア、原生動物など多くの微生物、即ち好気性微生物が関与することが必要である。そして、酸素が多く存在する環境下において活性化する好気性微生物は、酸素の少ない環境の下に多く存在する嫌気性微生物の100倍以上の分解効率を有しているといわれている。そのため、酸素があれば1日で分解できるヘドロの量も、酸素が足りない場合にはその分解に100日もかかるといわれている。 The soil in the breeding water can be freshly synthesized by applying sunlight to the aerobic microorganisms floating in the water by sterilizing microorganisms with ultraviolet rays or attaching them to filter media installed in the pond. This is done by supplying water to activate aerobic microorganisms. In addition, it is necessary to involve many microorganisms such as bacteria and protozoa, that is, aerobic microorganisms, in the decomposition of organic matter deposited on the bottom of the pond, generally called sludge. And it is said that the aerobic microorganism activated in the environment where oxygen is abundant has the decomposition efficiency of 100 times or more of the anaerobic microorganism which exists abundantly in the environment where oxygen is low. Therefore, the amount of sludge that can be decomposed in one day if oxygen is present is said to take 100 days if oxygen is insufficient.

上記課題を解決するために、本発明は、池中心に設置したタワー槽の内外に第1,2エアー噴出器をそれぞれ設置し、タワー槽内およびタワー槽外周にそれぞれ設置したエアー噴出器からエアーバブルを噴出すると池の中心に上向きの対流が発生し、且つ、酸素を供給して水を活性化し、回転アームをゆっくり回転して水面を波立たせて大気中の空気を取り込んだ新鮮な水にし、池全体に水平方向および縦方向に大きな水の対流を発生させ、好気性菌を活性化して嫌気性菌の増殖を抑えるとともに太陽光により光合成を行い、また太陽からの紫外線により水中の悪玉菌(病原菌)を殺菌して分解を早めるものである。 In order to solve the above-mentioned problems, the present invention has first and second air ejectors installed inside and outside the tower tank installed at the center of the pond, respectively, and air is supplied from the air ejectors installed in the tower tank and the outer circumference of the tower tank. When the bubble is blown out, upward convection occurs in the center of the pond, and oxygen is supplied to activate the water, and the rotating arm is slowly rotated to make the water surface rippling into fresh water that has taken in atmospheric air. , By generating large convection of water in the horizontal and vertical directions throughout the pond, activating aerobic bacteria to suppress the growth of anaerobic bacteria, photosynthesis by sunlight, and bad bacteria in the water by ultraviolet rays from the sun It kills (pathogenic bacteria) and accelerates decomposition.

従来のポンプは、養殖池の水の対流に強いところ(水面部分)と、弱いところ(水底部分)との間に差が生じるという欠点を有していた。しかるに本発明は、モータをゆっくり回転させるため、従来のポンプの約40分の1程度のエネルギーにより、対流の弱い水底部分にエアー噴出器を設置し、強制的にエアーを噴出させて上昇流を発生させ、従来のポンプでは不可能であった水底水に対流を発生させることにより養殖池の水面と水底の水質(DO,PH,BOD)に差を生じないようにして、池の水質を均一化することができた。 The conventional pump has a drawback that a difference is generated between a place where water is strong (water surface part) and a place where water is weak (water bottom part) in the pond. However, according to the present invention, in order to rotate the motor slowly, an air blower is installed on the bottom of the bottom where convection is weak, using about 1 / 40th of the energy of a conventional pump, and the air is forcibly ejected to generate an upward flow. By generating convection in the bottom water that was impossible with conventional pumps, the water quality of the pond and the bottom (DO, PH, BOD) of the aquaculture pond is not made different, and the water quality of the pond is uniform. I was able to.

そのうえ、従来のこの種の装置では、水底に魚の糞や餌の残りが沈殿してヘドロとなって停留していたが、本装置は、養殖池の底部に設置したストレーナと、補助濾過槽とを連結する連結管の自然落差を利用して自動的に養殖池内のヘドロを補助濾過槽に設けた分離室に移動させることにより、養殖池内にヘドロが停留しないようにする。 In addition, in this type of conventional device, fish droppings and food residue settled on the bottom of the water and remained as sludge, but this device is equipped with a strainer installed at the bottom of the aquaculture pond, an auxiliary filtration tank, The sludge in the culture pond is automatically moved to the separation chamber provided in the auxiliary filtration tank by using the natural head of the connecting pipe connecting the sludge so that the sludge does not remain in the culture pond.

さらに、養殖池の中心のデッドスペースを利用し、該スペースに設置したタワー槽内には、表面に多数の小孔を有した発泡プラスチックなどの小型の軽量素材の表面に多数の微生物が付着して形成した生活膜を有した多数の流動担体濾材を移動可能に収容してある。そして、タワー槽の内側底部に設けた第1エアー噴出器からエアーバブルを噴出させてエアレーションすることにより、タワー槽内を自由に流動する流動担体濾材の表面に付着した好気性微生物に酸素を供給して活性化した後、この処理水はタワー槽から外部に出て池の中心に流入する。 Furthermore, using the dead space at the center of the aquaculture pond, a large number of microorganisms adhere to the surface of a small lightweight material such as foamed plastic with a large number of small holes in the tower tank installed in the space. A large number of fluid carrier filter media having living membranes formed in this manner are accommodated in a movable manner. And by supplying air bubbles to the aerobic microorganisms adhering to the surface of the fluid carrier filter medium that freely flows in the tower tank by aerating air bubbles from the first air blower provided at the inner bottom of the tower tank After being activated, this treated water exits from the tower tank and flows into the center of the pond.

養殖池内の底部に設置したストレーナに集められたヘドロは、連結管の自然落差により自動的に補助濾過槽に移動し、この補助濾過槽に設けた分離室内において比重差により水から分離し、定期的に外部に送られ汚泥処理装置によりヘドロを回収して有効に利用する。さらに、補助濾過槽内の生物濾過材により高度生物処理された処理水はエアリフトにより養殖池に戻すものである。 The sludge collected on the strainer installed at the bottom of the aquaculture pond automatically moves to the auxiliary filtration tank due to the natural drop of the connecting pipe, and is separated from the water by the specific gravity difference in the separation chamber provided in this auxiliary filtration tank. The sludge is collected by the sludge treatment device and used effectively. Furthermore, the treated water that has been highly biologically treated with the biological filter material in the auxiliary filtration tank is returned to the culture pond by an air lift.

上記課題を達成するために本発明は、放射方向に配した複数のアーム17の先端下部に水掻羽根20を設けた回転アーム16を水面に浮かべて底部に樹立した支柱13に取付けた耕水機15と、壁面部3の内側に間隙部4を存して設けた炭素繊維濾過材6と、底部5に設けたヘドロ収集用のストレーナ9と、壁面部3を具えて中心方向に下り勾配の底部5を有した養殖池の中心に設置して、エアーバブルにより流動するバイオフィルタ11を内部に収容したタワー槽10と、ガラス発泡濾過材を積層してなる生物濾過材37を内部に収容して補助濾過槽35の下方に前記ストレーナと連通する分離室40を設け、生物濾過材で処理した処理水を養殖池に戻すエアリフト48を補助濾過槽の上部に設け、タワー槽10の内外に設置した第1,2エアー噴出器23,32とエアー源26を接続し、分離室40で比重差を利用して水から分離したヘドロをバルブ操作で排水管41を介して汚泥処理装置42に移送してヘドロを除去する。また、前記バイオフィルタ11は、微生物が付着しやすいように表面に多数の突起を有して、小型でプラスチックなどの軽量素材で任意形状に設けた多数の流動担体濾材11aをタワー槽10内に流動可能に収容して形成してある。さらに、前記補助濾過槽35内に収容する生物濾過材37は、水中の微生物が付着できるように夫々表面に多数の小孔を設けて小さな空間を多数有したガラス発泡濾過材を積層してある。さらにまた、前記壁面部3の外周面のナノカーボンヒータ50を装着してある。 In order to achieve the above-mentioned object, the present invention is a cultivated water attached to a support column 13 established at the bottom by floating a rotary arm 16 provided with water blades 20 at the lower ends of a plurality of arms 17 arranged in a radial direction. Machine 15, carbon fiber filter medium 6 provided with a gap 4 inside wall surface 3, sludge collecting strainer 9 provided on bottom 5, and wall surface 3, and a downward slope in the central direction. Is installed in the center of the aquaculture pond having the bottom part 5 and accommodates in the inside a tower tank 10 in which the biofilter 11 that flows by air bubbles is housed, and a biological filter material 37 formed by laminating glass foam filter media. A separation chamber 40 communicating with the strainer is provided below the auxiliary filtration tank 35, and an air lift 48 for returning the treated water treated with the biological filter material to the aquaculture pond is provided at the upper part of the auxiliary filtration tank. Installed first and second The air jets 23 and 32 and the air source 26 are connected, and the sludge separated from the water using the specific gravity difference in the separation chamber 40 is transferred to the sludge treatment device 42 through the drain pipe 41 by valve operation to remove the sludge. To do. Further, the biofilter 11 has a large number of protrusions on the surface so that microorganisms can easily adhere to it, and a large number of fluid carrier filter media 11 a provided in an arbitrary shape with a lightweight material such as plastic in the tower tank 10. It is formed so as to be able to flow. Furthermore, the biological filter medium 37 accommodated in the auxiliary filter tank 35 is formed by laminating glass foam filter mediums having a large number of small holes on the surface so that microbes in the water can adhere to each other. . Furthermore, a nanocarbon heater 50 on the outer peripheral surface of the wall surface portion 3 is mounted.

養殖池の壁面部の内側に炭素繊維濾過材を装着し、水面に浮上させた耕水機の回転アームが回転して池表面の中心から遠心方向に水を押し出し、その分、池の底部から酸素不足の水を上昇させて、水面において大気中の酸素を取り込み、太陽からの紫外線によって汚染物質中の悪玉菌を滅菌する。また、タワー槽内の第1エアー噴出器から噴出するエアーによって流動担体濾材に微生物が付着したバイオフィルタを活性化する。 A carbon fiber filter material is attached inside the wall of the aquaculture pond, and the rotating arm of the cultivator floated on the surface of the water rotates to push water from the center of the pond in the centrifugal direction. The oxygen-deficient water is raised, oxygen in the atmosphere is taken up on the water surface, and bad bacteria in pollutants are sterilized by ultraviolet rays from the sun. Moreover, the biofilter in which microorganisms adhere to the fluid carrier filter medium is activated by the air ejected from the first air ejector in the tower tank.

さらに、嫌気性ヘドロの原因となる魚の糞や残餌などが底部に堆積しないよう池の底部に設置したエアー噴出器から噴出するエアーバブルを上方に噴出して酸素不足の水に酸素を供給し、池の中心に上方向への対流を発生させる。また水面上の回転アームはゆっくり回転するため、従来の水車に比べて力の小さいモータを使用でき、そのため消費電力量を少なくし、大きな騒音を発生させることなく静かに運転ですることができる。 In addition, an air bubble blown upward from an air blower installed at the bottom of the pond to supply oxygen to oxygen-deficient water so that fish droppings and residual food that cause anaerobic sludge do not accumulate at the bottom. Generate upward convection in the center of the pond. In addition, since the rotating arm on the water surface rotates slowly, a motor having a smaller force than that of a conventional water wheel can be used, so that the power consumption can be reduced and the operation can be quietly performed without generating a large noise.

池の底部に設けたストレーナと、高度生物処理を行う生物濾過材を有した補助濾過槽の底部に設けた分離室とを連結管で連結し、該ストレーナに集まったヘドロは自然落差を利用して分離槽に移送し、比重差を利用して分離したヘドロは分離槽の底部に堆積し、一定量溜まるとバルブは開弁し、ヘドロを含む水を汚泥処理装置に移送し、ヘドロを圧縮、乾燥して植物の肥料などにする。へドロを除去した廃水は、例えば許可されている自治体にあっては、下水道に排水でする。また、許可されていない場合には、必要に応じて処理した後に排水することになる。さらに、」この補助濾過槽内で生物濾過材により高度生物処理された処理水は、エアリフトにより養殖池に戻される。 The strainer provided at the bottom of the pond is connected to the separation chamber provided at the bottom of the auxiliary filtration tank having a biological filter material for performing advanced biological treatment with a connecting pipe, and the sludge collected in the strainer uses a natural head. The sludge separated by utilizing the difference in specific gravity accumulates at the bottom of the separation tank, and when a certain amount of water accumulates, the valve opens, and the water containing sludge is transferred to the sludge treatment device, and the sludge is compressed. Dry it into plant fertilizer. Wastewater from which sludge has been removed is drained into the sewer system, for example, in an authorized municipality. Moreover, when it is not permitted, it will drain after processing as needed. Furthermore, the treated water that has been highly biologically treated with the biological filter material in this auxiliary filtration tank is returned to the culture pond by an air lift.

本発明は、池の底部中心に設置したタワー槽の内外に設置したエアー噴出口からエアーバブルを噴出して、池中心の上方に水流を発生して水面に放射方向への水流を発生させ、池全体に対流を発生させると共に、水底部に漂う酸素が不足した水に前記エアーバブルから酸素を供給する。さらに、タワー槽内に好気性微生物を表面に付着させた流動担体濾材からなるバイオフィルタを流動可能に収容してエアレーションを行って好気性微生物に酸素を供給し、また、水面に浮かべた回転アームをゆっくり回転させることにより水平方向に水流を発生させ、周縁部の壁面部の内側の取付けた炭素繊維濾過材、好気性菌に酸素を供給して活性化し、該養殖池内に残餌や糞を停留させないようにする。このバイオフィルタはタワー槽内を自由に流動し手いるので汚れることがないため、流動担体濾材を保守点検する必要がない。 The present invention spouts air bubbles from the air outlets installed inside and outside the tower tank installed in the center of the bottom of the pond, generates a water flow above the center of the pond and generates a water flow in the radial direction on the water surface, Convection is generated in the entire pond, and oxygen is supplied from the air bubbles to water deficient in oxygen drifting at the bottom of the water. In addition, a biofilter made of a fluid carrier filter medium with aerobic microorganisms attached to the surface in a tower tank is stored in a flowable manner to perform aeration, supply oxygen to the aerobic microorganisms, and a rotating arm floating on the water surface. The water is generated in the horizontal direction by slowly rotating the carbon fiber filter material attached inside the wall surface of the peripheral edge, activated by supplying oxygen to the aerobic bacteria, and residual food and feces in the aquaculture pond. Do not stop. Since this biofilter flows freely in the tower tank and does not become dirty, there is no need to perform maintenance and inspection on the fluid carrier filter medium.

FIG. 1 is a schematic view of a vertical section of a water treatment device installed in an aquaculture pond, and FIG. 2 shows the inside and outside of a tower tank installed on a strainer provided at the bottom of the pond. Fig. 3 is an enlarged sectional view in the direction of the line A-A in Fig. 2, and Fig. 4 is a rotary arm of a water cultivator installed on the water surface of the aquaculture pond. It is a top view which shows the state of the swirl flow which arose on the water surface by the winding. Reference numeral 1 denotes an aquaculture pond having an arbitrary shape such as a circular shape or a substantially rectangular shape that contains water for breeding, and is formed of an inexpensive synthetic resin material such as polypropylene. A carbon fiber filtering material 6 is provided along the inside of the wall surface 3 of the culture pond, and first and second air ejectors 23 and 32 are installed inside and outside the tower tank 10 installed at the center of the pond. It is.

壁面部3に連続した底部5を備えた養殖池1は、該養殖池の中心に向かって下り勾配に形成し、水底近辺に漂う魚の残餌や糞などの浮遊物は、水の移動と共に徐々に傾斜下部に集まる。底部5の中心の深い部分には、浮遊物などの水底に堆積したヘドロを養殖池の外部に移送するための取出口8を設けてあり、池内の魚などが侵入しないよう網目壁9aを具えたストレーナ9を前記取出ロ8に連通して設置してある。ストレーナ9は、養殖池の大きさ又は形状などによっては池の底部5に複数設けてもよい。 The aquaculture pond 1 having a bottom 5 continuous to the wall surface 3 is formed in a downward slope toward the center of the aquaculture pond, and suspended matter such as residual fish and feces floating near the bottom of the water gradually move along with the movement of water. Gather at the bottom of the slope. In the deep part of the center of the bottom part 5, there is provided an outlet 8 for transferring sludge accumulated on the bottom of the water, such as suspended matter, to the outside of the aquaculture pond, and a mesh wall 9a is provided so that fish in the pond will not enter. A strainer 9 is installed in communication with the take-out rod 8. A plurality of strainers 9 may be provided on the bottom 5 of the pond depending on the size or shape of the pond.

養殖池1の水面1aに設置した回転アーム16は、水面に浮かべるため浮力を有した3本のアームを放射状に等間隔に連結し、各先端下部に水掻羽根20を取付け、該回転アームの中心部分にモータ15を設置して耕水機15を形成してある。このモータ15に連結した回転アーム16は、例えば1分間に3〜10回、好ましくは5〜6回位のゆっくりした速さで回転するのでモータは小型にして、消費電力が少ないという特徴を有している。 The rotating arm 16 installed on the water surface 1a of the aquaculture pond 1 has three arms with buoyancy to float on the water surface, which are radially connected at equal intervals. A water cultivator 15 is formed by installing a motor 15 at the center. The rotating arm 16 connected to the motor 15 rotates at a slow speed of, for example, 3 to 10 times, preferably 5 to 6 times per minute, so that the motor is small and consumes less power. doing.

回転アーム16の回転により、養殖池の中心から周縁部に向かってゆっくり押し出され、水面に設けた波立部21は、水面を旋回しながら放射方向に流動し、大気中の酸素を水中に取り込むと共に、太陽からの紫外線で悪玉菌を滅菌し、光合成により好気性微生物を増殖して活性化する。回転アーム16を構成する各アーム17の先端下部に、それぞれ水掻羽根20,20を垂設してあり、効率よく水を放射状に押し出して水面に波立部21を効果的に形成することができる。ここで、酸素が多く存在する環境下で活性化する好気性菌(バクテリア)は、酸素の少ない環境下で活性化する嫌気性菌の100倍以上の分解効率を有している。 The rotating arm 16 is slowly pushed out from the center of the aquaculture pond toward the periphery by the rotation of the rotating arm 16, and the undulating portion 21 provided on the water surface flows in a radial direction while swirling the water surface, taking oxygen in the atmosphere into the water. Sterilize bad bacteria with ultraviolet rays from the sun, and grow and activate aerobic microorganisms by photosynthesis.

This biofilter 11 has a large specific surface area by providing a large number of protrusions on the surface of a fluid carrier filter medium 11a formed in a small and arbitrary shape using a lightweight material such as a lightweight foamed plastic. Purify water stains using living organisms that form a living membrane formed by microorganisms. Since the fluid carrier filter medium 11a freely flows in the tower tank 12 by air bubbles, even if remaining food or feces are clogged, it always flows during operation. Therefore, there is an advantage that maintenance is unnecessary.

また、前記タワー槽の周囲の池の底部に、環状に形成したパイプの表面に多数の小孔を有してエアーバブルを発生する第2エアー噴出器32を設置し、該エアー噴出器は第2のパイプ31を介してエアー源26に接続している。 In addition, a second air ejector 32 that has a large number of small holes on the surface of the annularly formed pipe and generates air bubbles is installed at the bottom of the pond around the tower tank. It is connected to the air source 26 via two pipes 31.

A drain pipe 41 connected to the chamber is connected to a sludge treatment device 42.

生物濾過材37は、表面に多数の小孔を設けたガラス発泡濾過材から成り、各部材表面にはそれぞれ水中微生物を付着して形成した生活膜をなす生物である微生物、特に、好気性微生物に酸素を供給して高度生物処理を行うことにより該好気性菌を増殖して活性化することにより水を浄化する。 The biological filter medium 37 is made of a glass foam filter medium having a large number of small holes on the surface, and microorganisms that are living organisms formed by attaching underwater microorganisms to the surface of each member, particularly aerobic microorganisms. Water is purified by growing and aerobic aerobic bacteria by supplying oxygen to the water and performing advanced biological treatment.

養殖池内に設置したストレーナ9と分離室40とを連結管39で連結してあり、自然落差を利用してストレーナ9から分離室40に自動的に移送される。この分離室内のヘドロが一定量に達すると、分離室内に設けたセンサー41bが感知して排水管41に設けたバルブ41aを開いて汚泥処理装置42に移送し、汚泥処理装置42に設けてある圧縮機、乾燥機などにより汚水からヘドロを回収して除去し、繰り返し圧縮を行った後に乾燥させてクレソンなどの植物の肥料に加工する。 The strainer 9 installed in the aquaculture pond is connected to the separation chamber 40 by a connecting pipe 39, and is automatically transferred from the strainer 9 to the separation chamber 40 using a natural head. When the sludge in the separation chamber reaches a certain amount, the sensor 41b provided in the separation chamber senses it, opens the valve 41a provided in the drain pipe 41 and transfers it to the sludge treatment device 42, and is provided in the sludge treatment device 42. The sludge is collected and removed from the sewage using a compressor, dryer, etc., repeatedly compressed, dried, and processed into plant fertilizers such as watercress.

補助濾過槽35内の上方に設置した有底筒45は、その上端を上面板36aよりやや上方に位置して取付け、さらに、前記養殖池の水面より上方に一端を位置させて略水平に配した送水パイプ46の他端を下方に折曲げてなる縦パイプ46aの下端は、前記有底筒内の略中間部に位置している。また、前記エアー源26に連なる第1のパイプ24の第2分岐部24cに第2のバルブ25aを介して連結した送気パイプ25の下端は、前記縦パイプ46a内の中間部又は下端近辺に位置させてなるエアリフト48により、前記補助濾過槽35の上部に溜まった処理水1bは養殖池1に戻される。 The bottomed tube 45 installed above the auxiliary filtration tank 35 is attached with its upper end positioned slightly above the upper surface plate 36a, and further, one end positioned above the water surface of the aquaculture pond and arranged substantially horizontally. The lower end of the vertical pipe 46a formed by bending the other end of the water supply pipe 46 downward is positioned at a substantially middle portion in the bottomed cylinder. The lower end of the air supply pipe 25 connected to the second branch portion 24c of the first pipe 24 connected to the air source 26 via the second valve 25a is in the middle of the vertical pipe 46a or near the lower end. The treated water 1b accumulated in the upper part of the auxiliary filtration tank 35 is returned to the culture pond 1 by the air lift 48 that is positioned.

次に、本実施形態の作用について説明すると、多数の魚類を収容した養殖池1の水面に設置した耕水機18とエアー源26を外部電力に接続して耕水機の回転アーム16を回転させ、エアー源26からのエアーを、パイプ24,31を介して養殖池の中心に設けたタワー槽10の内外に設置した第1,2エアー噴出器23,32から夫々水中にエアーバブルを噴出させるものである。 Next, the operation of the present embodiment will be described. The cultivator 18 installed on the surface of the aquaculture pond 1 containing a large number of fishes and the air source 26 are connected to external power to rotate the rotary arm 16 of the cultivator. The air bubbles are blown into the water from the first and second air blowers 23 and 32 installed inside and outside the tower tank 10 provided in the center of the culture pond through the pipes 24 and 31, respectively. It is something to be made.

第1エアー噴出器23からタワー槽10内にエアーバブルを噴出してエアーレーションを行う。このタワー槽内に移動可能に収容されたバイオフィルタ11を構成する多数の流動担体濾材11aに噴出したエアーバブルによって生じた水流により、流動担体濾材を自由に流動させ、該流動担体濾材の表面に付着して形成した生活膜にエアーバブルに含まれる酸素を供給する。エアーバブルから酸素を供給すると、好気性微生物が増殖して活性化する。 Air bubbles are ejected from the first air ejector 23 into the tower tank 10 to perform aeration. The fluid carrier filter medium is freely flowed by the water flow generated by the air bubbles ejected to a large number of fluid carrier filter media 11a constituting the biofilter 11 movably accommodated in the tower tank, and the fluid carrier filter media is formed on the surface of the fluid carrier filter media. Oxygen contained in the air bubbles is supplied to the living membrane formed by adhesion. When oxygen is supplied from an air bubble, aerobic microorganisms grow and are activated.

タワー槽10内に移動可能に収容した多数の流動担体濾材11aの表面に多数の突起を設けて比表面積は拡大し、該表面に微生物が付着した生活膜を有するバイオフィルタ11は、前記濾過材6のように一定位置で作用させるのではなく、水流によってタワー槽内を自由に流動しながら、バイオフィルタに付着したバクテリア、原生動物などの微生物、特に、好気性微生物に酸素を供給して増殖させて活性化する。 A biofilter 11 having a living membrane with microorganisms attached to the surface of a large number of protrusions provided on the surface of a large number of fluid carrier filter media 11a movably accommodated in the tower tank 10 is the filter media. Instead of acting at a fixed position as in Fig. 6, it is allowed to grow by supplying oxygen to bacteria, protozoa, and other microorganisms attached to the biofilter, in particular aerobic microorganisms, while flowing freely in the tower tank by water flow To activate.

水底近辺に漂う酸素が不足した水は、嫌気性微生物を多く含んでおり、タワー槽10内に流入して第1エアー噴出器23から噴出するエアーバブルの酸素が供給されると、流動するバイオフィルタ11の表面に付着した好気性微生物に酸素が供給されて活性化し、活性化した水はタワー槽外の池中心の水面に流入する。 Water deficient in oxygen near the bottom of the water contains a large amount of anaerobic microorganisms, and flows into the tower tank 10 and is supplied with air bubble oxygen that is ejected from the first air ejector 23. Oxygen is supplied to the aerobic microorganisms attached to the surface of the filter 11 and activated, and the activated water flows into the water surface at the center of the pond outside the tower tank.

また、タワー槽10の外側に設置した第2エアー噴出器32から噴出したエアーバブルは、底部近辺の魚の汚物、残餌等のヘドロが漂って酸素不足の水に、酸素を供給すると共に、エアーバブルの噴出により対流のほとんどない池中心部分に上向きの水流を発生させ、それによって壁面部の水底近辺に漂っている濾過未処理水を池の中心方向に呼び込む作用が発生する。 In addition, the air bubbles ejected from the second air ejector 32 installed outside the tower tank 10 supply oxygen to water deficient in the presence of sludge such as fish filth and residual food in the vicinity of the bottom. An upward flow of water is generated in the center of the pond where there is little convection due to the eruption of bubbles, thereby causing the action of drawing unfiltered water drifting near the bottom of the wall surface toward the center of the pond.

耕水機の回転アーム16は、水面に浮上しながら比較的ゆっくり回転し、水面の水を放射方向に押し出して発生させた波立部21は、大気中の酸素を水中に取り込むと共に、太陽光中の紫外線によって水中の悪玉菌を滅菌する。この回転アームの回転により池中心の水は遠心方向に押し出される。回転アーム16により放射方向に押し出された水は、壁面部3の内側に設けた濾過材3に新鮮な水を供給し、該濾過材に付着している好気性微生物に酸素を供給して活性化する。この濾過材6は、炭素繊維のためその高い弾力性は長期間にわたって繊維と繊維との間に空間を保持するため、安定して微生物の付着と水の流れを確保することができる。 The rotary arm 16 of the cultivator rotates relatively slowly while ascending to the surface of the water, and the corrugated portion 21 generated by pushing water on the surface of the water in the radial direction takes oxygen in the atmosphere into the water and also in sunlight. Sterilize bad bacteria in water with UV light. The water at the center of the pond is pushed out in the centrifugal direction by the rotation of the rotating arm. The water pushed out in the radial direction by the rotary arm 16 supplies fresh water to the filter medium 3 provided inside the wall surface portion 3 and supplies oxygen to aerobic microorganisms adhering to the filter medium. Turn into. Since the filter medium 6 is a carbon fiber, its high elasticity maintains a space between the fibers for a long period of time, so that the attachment of microorganisms and the flow of water can be secured stably.

さらに、エアー源26から供給される一方のエアーは、分岐部24bを介して第1パイプ24を通ってタワー槽10内の底部に設置した第1エアー噴出器23から水中にエアーバブルを噴出し、該タワー槽内に収容して表面に微生物を多数付着させた流動担体濾材11aからなるバイオフィルタ11を流動させる。また、エアー源26から供給される他方のエアーバルブは、第2パイプ31を通って養殖池の底部に位置した前記タワー槽10の外側に設置した第2エアー噴出器32から水中にエアーバブルを噴出して、池の中心に上向きの水流を発生させ、また、底部近辺に漂う酸素不足の水を池中心に呼び込んで酸素を供給し、該水に含まれる好気性微生物を増殖して活性化した水を水面に上昇させる。 Further, one of the air supplied from the air source 26 ejects air bubbles into the water from the first air ejector 23 installed at the bottom of the tower tank 10 through the first pipe 24 via the branch portion 24b. The biofilter 11 made of the fluid carrier filter medium 11a accommodated in the tower tank and having a large number of microorganisms attached to the surface thereof is caused to flow. In addition, the other air valve supplied from the air source 26 allows air bubbles to flow into the water from the second air ejector 32 installed outside the tower tank 10 located at the bottom of the culture pond through the second pipe 31. Spouts to generate an upward water flow in the center of the pond, and oxygen-deficient water drifting near the bottom is drawn into the pond center to supply oxygen, and aerobic microorganisms contained in the water are grown and activated Water is raised to the surface.

養殖池の水面における水の対流により、飼育魚の残餌や糞などの浮遊物は経時的に降下し、底部5の斜面に沿って池の中心底部に移動し、網目壁9aからストレーナ9内に集められる。ストレーナ9内に集まった浮遊物などのヘドロは連結管39の自然落差を利用して自動で分離室40内に移動する。時間の経過により分離室内には、水から分離したヘドロが溜まるとセンサー40aが感知し、排水管41に設けたバルブ41aを開弁してヘドロを含む水を汚泥処理装置42に送る。該汚泥処理装置42は、水中に含まれるゴミを取り除くフィルタ手段とヘドロを絞って水分を除去し、さらにヘドロを圧縮手段により圧縮して水分を絞って乾燥させた後、粉状、穎粒状など任意の形状に形成し、クレソン等の植物の肥料に利用する。 Due to the convection of water on the surface of the aquaculture pond, the suspended fish such as residual food and feces descends over time, move along the slope of the bottom 5 to the center bottom of the pond, and enter the strainer 9 from the mesh wall 9a. Collected. Sludge collected in the strainer 9 automatically moves into the separation chamber 40 using the natural head of the connecting pipe 39. When sludge separated from water accumulates in the separation chamber over time, the sensor 40a senses it, and opens the valve 41a provided on the drain pipe 41 to send water containing sludge to the sludge treatment device 42. The sludge treatment device 42 removes moisture by squeezing the sludge with filter means for removing dust contained in the water, and further compressing the sludge with the compression means and squeezing the moisture to dry the powder, soot, etc. It is formed into an arbitrary shape and used as a fertilizer for plants such as watercress.

この分離室40内の水は、補助濾過槽35内に設けてある生物濾過材37によって高度生物処理されて活性化し、該補助濾過槽の上方に送られた処理水1bの水位が有底筒45の上端を超えると有底筒内に送られる。この有底筒内には、先端を養殖池の上部に位置した送水パイプ46の他端に連続して設けた縦パイプ46aと、エアー源26に連なる第1パイプ24に分岐部を介して連なる第2送気パイプ25とにより構成したエアリフト48により、エアー源26から供給されるエアーによって、該有底筒内の縦パイプ46a内の処理水は、送気パイプ25の先端から噴出するエアーにより有底筒内の処理水を縦パイプ内に上昇させ、送水パイプ46の先端から養殖池1内に戻すことができる。 The water in the separation chamber 40 is activated by being highly biologically treated by a biological filter medium 37 provided in the auxiliary filtration tank 35, and the water level of the treated water 1b sent above the auxiliary filtration tank is the bottomed cylinder. If the upper end of 45 is exceeded, it will be sent into the bottomed cylinder. In the bottomed cylinder, a vertical pipe 46a provided continuously with the other end of the water supply pipe 46 located at the top of the aquaculture pond, and a first pipe 24 connected to the air source 26 via a branch portion. The treated water in the vertical pipe 46a in the bottomed cylinder is supplied by the air blown from the tip of the air supply pipe 25 by the air supplied from the air source 26 by the air lift 48 constituted by the air supply pipe 25. The treated water in the bottom cylinder can be raised into the vertical pipe and returned to the culture pond 1 from the tip of the water supply pipe 46.

回転アーム16が回転すると、池の表層水はアームに設けた水掻羽根20によって回転アームの中心から放射方向に弧状に押し出しながら水面部分に波立部21を形成し、この波立部近辺の水に空気中の酸素を取り込んで溶存酸素(DO)値を高めると共に、太陽光線によって光合成を促進し、さらに、紫外線により水中に含まれる浮遊物中の雑菌を滅菌する。このように、水中に含まれる微生物の好気性バクテリアに酸素を供給して増殖させることにより活性化し、ヘドロの原因となる残餌や糞などの浮遊物を好気性微生物の作用により減少させ、好気性微生物を増殖して活性化する。 When the rotary arm 16 rotates, the surface water of the pond is formed in the water surface portion by forming the wave surface 21 while pushing out radially from the center of the rotary arm by the water blades 20 provided on the arm. Incorporates oxygen in the air to increase the dissolved oxygen (DO) value, promotes photosynthesis by sunlight, and sterilizes germs in the suspended matter contained in water by ultraviolet rays. In this way, it is activated by supplying oxygen to aerobic bacteria of microorganisms contained in water and growing them, and suspended matter such as residual food and feces that cause sludge is reduced by the action of aerobic microorganisms. Grows and activates aerial microorganisms.

池の底部に漂う酸素が不足した水は、エアー噴出器から噴出するエアーバブルによって池中心を上昇し、その間に酸素の不足した水は、水中でエアーバブルから酸素を取り込み、また、水面で酸素を取り込むと同時に太陽光線により水中のプランクトンの光合成が活性化し、さらに紫外線による殺菌効果が得られる。溶存酸素(DO)を十分に含んだ水は池底に淀んでいる嫌気的環境の原因となるヘドロの原因となる魚の糞や残餌に接触して嫌気性菌に代わって好気性微生物、即ち、有効微生物を増殖させることにより水質が改善する。このように溶存酸素の豊富な表層水は、酸素が不足する水底に送り込まれて池中の水が循環することにより水質が均一化し、酸素を含んだ水を底部にも供給して好気性菌の活性化によりヘドロの発生を防ぐことができる。このエアー源26と耕水機の回転アーム18は一日中作動する。 Water deficient in oxygen at the bottom of the pond rises up the center of the pond by air bubbles ejected from the air blower, while water deficient in oxygen takes oxygen from the air bubbles in the water and oxygen on the water surface. At the same time, the photosynthesis of plankton in the water is activated by sunlight, and the bactericidal effect by ultraviolet rays is obtained. Water that contains enough dissolved oxygen (DO) comes into contact with fish dung and residual food that causes sludge, which is an anaerobic environment in the bottom of the pond. Water quality is improved by growing effective microorganisms. In this way, the surface water rich in dissolved oxygen is sent to the bottom of the oxygen deficient and the water in the pond is circulated, so that the water quality becomes uniform and the oxygen-containing water is supplied to the bottom as well. Generation of sludge can be prevented by activation of. The air source 26 and the rotary arm 18 of the tiller operate all day.

ヘドロを分離室40から汚泥処理装置42に排出するためのバルブを作動するセンサーの代わりに、一定時間毎に作動するようにタイマーを設けて作用させてもよいのはもちろんである。さらに、ポリプロピレンで製造した養殖池の壁面部に、ナノカーボンヒータ50を装着したことにより、室内でも光合成をしながら遠赤外線を発生させて魚の成長を一段と促進させることができる。その上、従来設備の10分の一くらいで、養殖密度は3〜5倍位となり、養殖効率が一段と向上する作用を有する。その上、本装置に対するメンテナンスに要する費用を一段と軽減することができるという特徴を有する。 Of course, instead of a sensor that operates a valve for discharging sludge from the separation chamber 40 to the sludge treatment device 42, a timer may be provided so as to operate at regular intervals. Furthermore, by attaching the nanocarbon heater 50 to the wall portion of the culture pond made of polypropylene, far-infrared rays can be generated while photosynthesis is carried out indoors to further promote the growth of fish. In addition, the aquaculture density is about 3 to 5 times that of conventional equipment, and the aquaculture efficiency is further improved. In addition, there is a feature that the cost required for maintenance of the apparatus can be further reduced.
