Description
本発明は、光合成によりオイルを生産する微細藻類を培養するための池とその作製方法に関するものである。 The present invention relates to a pond for culturing microalgae producing oil by photosynthesis and a method for producing the same.
近年、新たな再生可能エネルギーの一つとして、微細藻類が産生するオイル生産などの「バイオマス」の活用が注目されている。微細藻類は、一般的には水中に存在する顕微鏡サイズの藻で、その多くは植物と同様に、太陽光を利用して二酸化炭素を固定し、炭水化物を合成する光合成を行い、代謝物としてオイルを産生する。
微細藻類の培養施設としては、微細藻類と培養液の混合液を収納する長円形状の循環水路を成す培養池と流路内の混合液を撹拌するための撹拌装置を備えたものが知られている（例えば、特許文献１参照）。
In recent years, the use of “biomass” such as oil production produced by microalgae has attracted attention as one of the new renewable energies. Microalgae are microscopic algae that generally exist in water, and most of them, like plants, use sunlight to fix carbon dioxide, synthesize carbohydrates, and oil as metabolites. Produce.
Known culture facilities for microalgae include a culture pond that forms an elliptical circulation channel that contains a mixed liquid of microalgae and a culture solution, and a stirring device for stirring the mixed solution in the flow path. (For example, refer to Patent Document 1).
ところで、微細藻類を大量培養するためには、開放系の大規模培養施設が必要となるが、従来の数百ｍ2〜数千ｍ2規模の培養施設は、施設の安全性や安定性のため、コンクリート製の培養池が必要であった。
しかしながら、コンクリート製の培養池は、１００ｍ2程度の比較的小型のものであっても、建設費用が高価であるだけでなく、施工に要する期間が長くなってしまうといった問題点あった。
一方、ゴルフ場などの調整池などの水深が２０ｃｍ程度の浅い池の中には、地面を素掘りした中に直接防水シート貼った安価で短期間で作製できるものがあるが、素掘りの場合には、施工後に周辺から水が集まり、シートの底面や裏面に水が入り込んでシートを持ち上げる可能性があり、将来的にはシートが損傷する恐れがあるので、微細藻類を培養する培養池に適用することは困難である。
By the way, in order to mass-cultivate microalgae, an open-type large-scale culture facility is required, but conventional culture facilities of several hundred m 2 to several thousand m 2 have a safety and stability of the facility. Therefore, a concrete culture pond was necessary.
However, a concrete culture pond has a problem that even if it is a relatively small one of about 100 m 2 , not only is the construction cost expensive, but also the time required for construction becomes long.
On the other hand, some shallow ponds with a water depth of about 20 cm, such as a regulation pond in a golf course, can be made in a short period of time by cheaply attaching a waterproof sheet directly to the ground while digging the ground. In the culture pond where microalgae are cultivated, there is a possibility that water will collect from the surrounding area after construction and water may enter the bottom and back of the sheet and lift the sheet. It is difficult to apply.
本発明は、従来の問題点に鑑みてなされたもので、安全性や安定性を確保できるとともに、短期間で作製が可能な微細藻類培養池とその作製方法を提供することを目的とする。 The present invention has been made in view of conventional problems, and an object thereof is to provide a microalgae culture pond that can ensure safety and stability and can be produced in a short period of time, and a method for producing the same.

このように、素掘りをせず、地面にコンクリートブロックを用いて培養池の骨組みである外壁を作り、そこに防水シートを貼付けるようにすれば、規模も形状も好みのままの池を短期間で作り上げることができる。また、素掘りでなく、外壁を整地された地面から立ち上げるように構築したので、雨天時にも周囲の水が防水シートの裏面・底面に入り込むことがないので、培養池の安全性や安定性を確保できる。

And a waterproof sheet laid in a region surrounded by the outer wall and having an edge attached to the outer wall.
In this way, without digging, using concrete blocks on the ground to create an outer wall that is the framework of a culture pond and attaching a waterproof sheet to it, a pond of any scale and shape can be short-term It can be made up in between. In addition, since the outer wall was built up from the leveled ground instead of digging, the surrounding water does not enter the back and bottom surfaces of the waterproof sheet even in rainy weather, so the safety and stability of the culture pond Can be secured.
また、前記外壁と前記防水シートで囲まれた空間に収納される培養液を攪拌するための撹拌装置を設けて、培養した藻類を攪拌混合できるようにしたので、藻類の培養を効果的に行うことができる。

また、前記外壁内に、複数のコンクリートブロックを積層して成る内壁を設けて循環水路を形成するようにしたので、培養液を効果的に攪拌することができる。
In addition, since an agitating device for agitating the culture solution stored in the space surrounded by the outer wall and the waterproof sheet is provided so that the cultured algae can be stirred and mixed, the algae can be cultured effectively. be able to.
Further, a float member floating on a liquid containing the microalgae stored in the microalgae culture pond and the culture solution of the microalgae, a water wheel mounted on the float member, and a drive device for rotating the water wheel Since the stirrer provided with is provided, the degree of freedom of the installation position of the stirrer can be increased.
In addition, if a bubble generator mounted on the float member and discharging bubbles into the liquid is used instead of a water wheel, the degree of freedom of the installation position of the stirring device can be increased, and not only the generation of water flow. In addition, since carbon dioxide can be injected and dissolved in the culture solution, which is effective for promoting the culture of algae, microalgae can be cultured effectively.
Moreover, since the inner wall formed by laminating a plurality of concrete blocks is provided in the outer wall to form the circulating water channel, the culture solution can be effectively stirred.
