Description
本発明は、上水道をはじめ工業用水道、産業廃水処理等の沈澱池における濁水の処理を、一部の沈澱池を休止した場合においても、濁水の処理量を保持した状態で濁水の処理を行う連続処理運用方法に関する。 The present invention treats turbid water in sedimentation ponds such as waterworks, industrial water supply, industrial wastewater treatment, etc., even when some of the sedimentation ponds are suspended, turbid water treatment is carried out while maintaining the amount of turbid water treatment. The present invention relates to a continuous processing operation method.
従来、上水道をはじめ工業用水道、産業廃水処理等の沈澱池における濁水を処理する場合、処理量を確保するため複数の沈澱池を用いて処理する方法が一般的に行われている。すなわち、横流沈澱池を例にとれば、混和池で濁水に凝集剤が添加され、次のフロック形成池において急速撹拌が行われて均一に混合された後沈澱池の緩速撹拌部においてゆっくり撹拌を行ってフロックの生成を行い、さらに沈殿部において、生成したフロックを沈降させて清澄化処理を行い、沈澱池装置外に排出させていた。しかしながら沈殿池を長期間使用していると設備の故障とか沈澱池内の傾斜板などの保守整備等を用うために一時的に一部の沈澱池を停止しなければならなかった。
このような場合は、休止した沈澱池の処理量に見合う量の濁水に減少させなければならなかった。
また他の方法としては、目的とする濁水の処理量より多く処理できる沈殿処理施設を予め造って対応していたが、この場合沈殿処理施設を建設するスペースを必要とする外、莫大な建設費用を要する問題点があった。
Conventionally, when treating muddy water in sedimentation basins such as waterworks, industrial water supply, and industrial wastewater treatment, a method of treating using a plurality of sedimentation basins is generally performed in order to secure a treatment amount. For example, in the case of a cross-flow sedimentation basin, a flocculant is added to the turbid water in the mixing basin, and after the next floc-forming pond is rapidly stirred and mixed uniformly, it is slowly stirred in the slow stirring section of the sedimentation basin. Then, flocs were generated, and in the sedimentation part, the generated flocs were settled and clarified, and discharged out of the sedimentation basin apparatus. However, if the sedimentation basins have been used for a long time, some sedimentation basins had to be temporarily stopped in order to use equipment maintenance or maintenance of sloping plates in the sedimentation basins.
In such a case, it was necessary to reduce to an amount of turbid water commensurate with the throughput of the resting sedimentation basin.
As another method, a sedimentation treatment facility capable of treating more than the target amount of turbid water was prepared in advance. In this case, a space for constructing the precipitation treatment facility is required, and a huge construction cost is required. There was a problem that required.
本発明は、沈殿処理施設において、一部の沈澱池を休止させた場合にも、休止前の濁水の処理量と水質を確保する方法について種々研究を重ねた結果、既存の沈殿池のみで処理する方法を見出し、本発明を完成するに至った。 In the present invention, even when some sedimentation basins are suspended in the sedimentation treatment facility, as a result of various researches on how to ensure the treatment amount and quality of muddy water before the suspension, the treatment is performed only with existing sedimentation basins. The present inventors have found a method to do this and have completed the present invention.
すなわち、本発明は、複数の沈澱池を同時に使用して濁水を清澄化処理する沈殿処理施設において、少なくとも一つの沈澱池を休止したときに、他の使用している沈殿池の少なくとも一つの沈澱池に、水流傾斜膜を各々隣接する水流傾斜膜との間に間隙を設けて連結した整流膜を複数条展張することを特徴とする、濁水の処理量を減少させることなく処理することができる濁水の連続処理運用方法である。 That is, the present invention relates to a sedimentation treatment facility that uses a plurality of sedimentation basins simultaneously to clarify turbid water, and when at least one sedimentation basin is suspended, at least one sedimentation of another sedimentation basin used. It is possible to treat the turbid water without reducing the amount of turbid water, which is characterized in that a plurality of rectifying membranes are connected to the pond with a gap between the water gradient membranes and adjacent water gradient membranes. It is a continuous treatment operation method for muddy water.
本発明によれば、沈殿処理施設の一部の沈澱池を休止させた場合においても、既存の沈澱池のみで休止前の濁水の処理量を確保することは勿論、それ以上の処理量を確保することができる。また従来は、沈澱処理施設を建設する場合にも休止する沈殿池を想定して、目標とする濁水の処理量以上の能力を有するように設計しなければならず、そのため設置面積の拡大と共に、建設費用がかかると云う問題もあったが本発明はその問題も解決することができる。 According to the present invention, even when some of the sedimentation basins in the sedimentation treatment facility are suspended, it is possible to secure the treatment amount of turbid water before the suspension only with the existing sedimentation basin, as well as the further treatment amount. can do. Conventionally, assuming a sedimentation basin that is also suspended when constructing a sedimentation treatment facility, it must be designed to have a capacity equal to or greater than the target amount of turbid water treatment. Although there was a problem that the construction cost was high, the present invention can also solve the problem.
次に本発明の濁水の連続処理運用方法について説明する。
まず本発明に使用する整流膜について説明する。
本発明の整流膜は、例えば図1および図２に示すように、ロープ等を通す挿通口１を有するフロート２に水中膜３を垂下させた水流傾斜膜４を図３に示すように、フロート２の挿通口１にロープ５等を通して隣接する水中膜3との間に間隙を設けて連結させたものが使用できる。
また他の水流傾斜膜の態様としては、フロート２を用いずに、直接ロープ等に水中膜３を垂下させたものも好適に使用できる。
Next, the continuous treatment operation method for muddy water according to the present invention will be described.
First, the rectifying film used in the present invention will be described.
For example, as shown in FIG. 1 and FIG. 2, the rectifying membrane of the present invention has a
Moreover, as another aspect of the water flow gradient film, a film in which the
沈殿池内に展張する整流膜は、沈澱池内の濁水の流れ方向に対し、水流傾斜膜４の膜面を対向させる状態で設置することが好ましい。
またこの整流膜は、沈澱池内の濁水の流れ方向に対し、多重展張することが必要である。多重展張する場合の整流膜の前後の間隔は、沈澱池の形状及び大きさによって適宜決定することができる。
It is preferable that the rectifying membrane extended in the sedimentation basin is installed in a state where the membrane surface of the water
In addition, this rectifying membrane needs to be multiple-stretched with respect to the flow direction of muddy water in the sedimentation basin. The distance before and after the rectifying film in the case of multiple spreading can be appropriately determined according to the shape and size of the sedimentation basin.
整流膜の展張方法も図４に示すように沈殿池内にそれぞれ流れ方向に対し並列状にするように展張しても、また図５に示すように千鳥状に展張することもできる。
これらの整流膜を展張した場合、整流膜端部の水流傾斜膜４と沈澱池壁面との間に間隔が生じた場合には該間隔部近傍に阻流板６を設けることが好ましい。
As shown in FIG. 4, the rectifying film can be extended in parallel to the flow direction as shown in FIG. 4 or in a staggered manner as shown in FIG. 5.
When these rectifying films are stretched, if a gap is generated between the water
本発明における沈澱池の形状も円形、正方形、長方形のいずれの形状のものでも使用できるが、好ましくは長方形のものが最適である。 The shape of the sedimentation basin in the present invention can be any of a circular shape, a square shape, and a rectangular shape, but a rectangular shape is preferable.
