【考案の詳細な説明】
本考案は、湖水等の水面又は水面付近に浮遊する藻類や
植物性プランクトンを採集除去する浮遊微生物除去装置
に関するものである。[Detailed Description of the Invention] The present invention relates to a floating microorganism removal device that collects and removes algae and phytoplankton floating on or near the surface of water such as lake water.
近年、湖水は生活廃水の増大などに起因すると思われる
富栄養化現象が見られ、この進行と共に植物性プランク
トンの異常繁殖という現象が各地で生じている。In recent years, lake water has been experiencing a phenomenon of eutrophication, which is thought to be caused by an increase in domestic wastewater, and as this progresses, the phenomenon of abnormal proliferation of phytoplankton is occurring in various places.
この異常繁殖は湖面の美観をそこない、特有な悪臭がた
ちこめたり、水産被害の発生、水資源としての利用価値
の低下等の幣害を生じている。This abnormal growth is causing damage such as spoiling the beauty of the lake surface, emitting a peculiar odor, causing damage to fisheries, and decreasing the value of water as a resource.
この微生物発生の予防や原因除去についていろいろな対
策や実験が行なわれているが、効果のあるものがなかっ
た。Various measures and experiments have been carried out to prevent the occurrence of microorganisms and remove the causes, but none have been found to be effective.
最近これら浮遊微生物を採集除去する装置として、取り
入れた原水を船内に設けた分離槽に導き、分離槽内を静
かに横流させながら浮遊物を浮上分離させて、吸込器に
より採取し脱水機に送っている。Recently, as a device for collecting and removing these floating microorganisms, the raw water taken in is guided into a separation tank installed inside the ship, and suspended matter is floated and separated while flowing gently across the tank, collected by a suction device, and sent to a dehydrator. ing.
しかし、この浮上分離の滞留時間が大きいため分離槽が
相当大きくならざるを得す、さらに単なる浮上分離では
、分離槽の表面が乱れたり、浮上する前に分離槽外に出
たり （ショートパス）するので、藻類のような比重が
１に近いものでは分離効果が悪く不適当である。However, the residence time of this flotation separation is long, so the separation tank has to be quite large.Furthermore, simple flotation separation may disturb the surface of the separation tank or leave the separation tank before floating (short path). Therefore, materials with a specific gravity close to 1, such as algae, have a poor separation effect and are inappropriate.
また脱水機には高価で消費動力の大きい遠心分離機など
が用いられ、除去能力のわりに装置が大型、高級化しコ
スト的に問題がある。In addition, the dehydrator uses an expensive centrifuge or the like that consumes a large amount of power, and the equipment is large and sophisticated in spite of its removal capacity, which poses a problem in terms of cost.
本考案は、これら従来の問題点を解決し浮遊微生物を効
果的に分離し、小型かつ低廉な装置を提供することを目
的とするものである。The present invention aims to solve these conventional problems, effectively separate airborne microorganisms, and provide a small and inexpensive device.

水面浮遊微生物除去装置である。The present invention provides a floating material introduction section at the front of the hull, and connects the introduction section into a micro strainer, and the micro strainer is composed of a rotatably installed cylindrical screen drum. A hopper with a suspended matter discharge pipe was installed in an open manner, and a nozzle connected to a water supply pipe was installed outside the drum, and the outside of the micro strainer was communicated with a propulsion device installed at the rear of the hull via a water supply channel. This is a water surface floating microorganism removal device.

A movable weir 2 that is lower than the water surface is movably attached to a partition plate 4 connected to the bottom 3 of the ship at the front of the hull in the area surrounded by the water. A micro strainer 6 is disposed at the rear end of the storage chamber 5, and the storage chamber 5 and the inside of the micro strainer 6 communicate with each other.

水の吸い込みを行なうようになっている。Furthermore, a water conduit 12 is provided below the outside of the micro strainer 6 and communicates with a sedimentation device 13 such as a side thruster installed at the rear of the hull, and the separated liquid separated from floating microorganisms by the micro strainer is transferred to the water conduit 12. By discharging the raw water from the sedimentation device 13 through the above, the ship moves forward and the raw water is sucked in.

ようになっている。On the other hand, the clarified separated liquid passes through a cylindrical screen, passes through a water supply channel 12 below the outside of the micro-strainer 6, and is discharged out of the vessel from a sedimentation device 13, which moves the hull forward and near the water surface. The floating microorganisms are sucked into the storage chamber 5 together with water, and the floating microorganisms can be collected and removed efficiently.

く節減できるものである。As described above, the present invention separates raw water containing floating microorganisms using a micro strainer, and discharges the separated liquid out of the system from a sedimentation device installed at the rear of the hull.
The simple structure can increase the overspeed for separating airborne microorganisms, making the hull smaller, easy to handle, and allowing the hull to be deposited and sucked in raw water, resulting in low power consumption and processing capacity. In particular, the micro strainer consists of a rotatable cylindrical water screen drum, in which a hopper with a suspended solids discharge pipe is opened and a nozzle connected to the water supply pipe is installed. By placing it outside the drum, the screen can be easily purified and the floating matter can be discharged with appropriate efficiency.The hopper inside the screen allows stable removal of overflowing floating matter, and there is no short path, making it extremely economical. This makes it possible to reduce construction costs and significantly reduce processing costs.
