Description

本発明は、水流がある水路、河川等における汚濁水の除濁方法に関する。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method for removing polluted water in a channel, river or the like where there is a water flow.

従来、汚濁水の除濁方法については、種々の方法が提案されている。特に代表的なものとしては、フロートに垂下膜を設けた水流傾斜板を連設したものが知られている。そしてこれら水流傾斜板を種々の形態に展張することが提案されている。例えば水流傾斜板を水流に対して、対向して展張したり、また水流に対して斜めに展張したりして処理を行なっている。また水流傾斜板を井に連続して設ける方法も知られている。 Conventionally, various methods have been proposed for removing polluted water. In particular, as a representative one, there is known one in which a water flow inclined plate provided with a hanging film is connected to a float. It has been proposed that these water flow inclined plates be expanded in various forms. For example, the treatment is performed by expanding the water flow inclined plate opposite to the water flow, or expanding it obliquely to the water flow. There is also known a method of continuously providing a water flow inclined plate in a well.

しかしながら、前記水流傾斜板を従来知られた展張方法によって汚濁水を処理した場合、水流が穏やかな時には所期の目的を達成することはできるが、水流の流速が速くなると、垂下膜の吹き上がり現象が生起するようになり、除濁能力が低下する傾向があった。
そこで本発明者は、水流の流速が速くなっても水流傾斜板の除濁能力を低下させることのない、展張方法について種々研究を重ねた結果本発明を完成するに至った。 However, when the polluted water is treated by the previously known spreading method of the water flow inclined plate, the desired purpose can be achieved when the water flow is mild, but when the flow velocity of the water flow is increased, the falling film blows up There was a tendency for the phenomenon to occur and the ability to remove turbidity to decrease.
Then, the present inventors came to complete this invention, as a result of repeating various research about the expansion method which does not reduce the turbidity removal ability of a water flow inclination plate, even if the flow velocity of water flow becomes quick.

すなわち、本発明は、水流のある水域に、流水方向に対しフロートに垂下膜を設けた、水流傾斜板をジグザク状に連設して長手方向に設け、かつ該ジグザグ状水流傾斜板と隣接するジグザク状水流傾斜板との間に間隔を設けて多重展張することを特徴とする汚濁水の除濁方法である。 That is, according to the present invention, a water flow inclined plate provided with a hanging film on the float with respect to the flowing water direction is continuously provided in a zigzag manner in a water area with water flow, and is adjacent to the zigzag water flow inclined plate This is a method for removing polluted water characterized by providing multiple gaps with a gap between it and a zigzag water flow inclined plate.

本発明の除濁方法によれば、水流が速い場合でも水流の干渉現象を生起すると共に、展張手段によって垂下膜の吹き上がりを防止することができ、かつジグザク状に展張することによって多数の淀み個所が設けられていることから汚濁水中の汚濁粒子を効率的に捕捉することができる。 According to the method of removing turbidity of the present invention, even when the water flow is fast, the interference phenomenon of the water flow can be generated, and the blowup of the hanging film can be prevented by the spreading means, and many stagnation by stretching in a zigzag shape. The provision of the points makes it possible to efficiently capture polluted particles in the polluted water.

次に本発明を図面を参照しながら説明する。
図１に示すように、水流傾斜板１は、略円筒型の長方形のフロート２の下部に垂下膜３を設け、前記フロート２の両端部に連結具４を設けてなるものである。垂下膜３の下端部５には重錘を設けることが好ましい（図示せず）。
本発明は、前記水流傾斜板１を用い、図２に示すように、ジグザク状に連設し、かつ図３に示すように、隣接するジグザク状水流傾斜板６との間に間隔Ｈを設けて多重展張する。
またジグザク状水流傾斜板６の他の展張方法としては図４に示すように対称形となるように展張することもできる。さらに他の態様として図５に示すように、隣接するジグザク状水流傾斜板６に比して前後にずらせて設置することもできる。
さらに図６に示すように、ジグザグ状水流傾斜板６の上流側に流れを横断するように水流傾斜板１を直線状に連設した水流傾斜板７の下流側に、隣接するジグザク状水流傾斜板６との間に間隔を設けて多重展張することもできる。また図７に示すように、ジグザグ状水流傾斜板６の上流側に流れを横断するように水流傾斜板１をＶ字状に連設した水流傾斜板７を設置することもできる。
このように流れを横断するように水流傾斜板１を設けることによって、水流の流速を弱めると共に、整流化を行うことができるので除濁効果が一層向上する。 The invention will now be described with reference to the drawings.
As shown in FIG. 1, the water flow inclined plate 1 is formed by providing a hanging film 3 under the substantially cylindrical rectangular float 2 and providing connectors 4 at both ends of the float 2. It is preferable to provide a weight at the lower end portion 5 of the hanging film 3 (not shown).
According to the present invention, the water flow inclined plate 1 is used to continuously connect in a zigzag shape as shown in FIG. 2 and as shown in FIG. 3, a space H is provided between adjacent water flow inclined plates 6. Over-expansion.
Further, as another method of expanding the zigzag water flow inclined plate 6, it is possible to expand so as to be symmetrical as shown in FIG. Furthermore, as shown in FIG. 5 as another aspect, it can also be installed by being shifted back and forth relative to the adjacent zigzag water flow inclined plate 6.
Further, as shown in FIG. 6, a zigzag water flow inclination adjacent to the downstream side of the water flow inclination plate 7 in which the water flow inclination plate 1 is linearly arranged so as to cross the flow on the upstream side of the zigzag water flow inclination plate 6. It is also possible to provide multiple spacing with the plate 6 for multiple expansion. Further, as shown in FIG. 7, it is also possible to install a water flow inclined plate 7 in which the water flow inclined plates 1 are continuously provided in a V shape on the upstream side of the zigzag water flow inclined plate 6 so as to cross the flow.
Thus, by providing the water flow inclined plate 1 so as to cross the flow, the flow velocity of the water flow can be reduced and the rectification can be performed, thereby further improving the turbidity removal effect.

本発明のジグザク状水流傾斜板６を構成する時に、その一辺は水流傾斜板１を目的に応じて１個以上連結して構成することができる。ジグザグ状水流傾斜板の角部の角度αは７０〜１７０°、好ましくは９０〜１５０°であることが好ましい。
また隣接するジグザグ状水流傾斜板６との間隔Ｈは、水流の流速にもよるが、一般的に１〜２０ｍ設けることによって水流の干渉現象および除濁効率が上がるので好ましい。
さらに本発明の除濁方法は特に水流の流速が０．５〜１．５ｍ／Ｓの場合にも卓越した効果を有する。 When constructing the zigzag water flow inclined plate 6 of the present invention, one side thereof can be formed by connecting one or more water flow inclined plates 1 according to the purpose. The angle α of the corner of the zigzag water flow inclined plate is preferably 70 to 170 °, preferably 90 to 150 °.
Further, although the distance H between the adjacent zigzag water flow inclined plates 6 depends on the flow velocity of the water flow, it is generally preferable to provide 1 to 20 m because the interference phenomenon of the water flow and the turbidity removal efficiency increase.
Furthermore, the turbidity removal method of the present invention is particularly effective even when the flow velocity of the water flow is 0.5 to 1.5 m / s.
