Description

本発明は凝集反応装置に係り、特に懸濁物質（ＳＳ）や油等の汚濁物質を含んだ水から汚濁物質を分離する際、凝集反応によって凝集汚泥を生成して処理する凝集反応装置に関する。 The present invention relates to an agglomeration reaction apparatus, and more particularly to an agglomeration reaction apparatus that generates and treats an agglomerated sludge by an agglomeration reaction when separating a pollutant from water containing a contaminant such as a suspended substance (SS) or oil.

従来、用水処理や排水処理においては、凝集反応装置に処理対象とする原水（被処理水）と共に無機系または有機系の凝集剤を注入して被処理水中に含まれる懸濁物や溶解物を凝集させ、凝集フロックとして除去することが行われている。
この種の装置としては、竪型湿式造粒装置が知られている（例えば、特許文献１を参照）。これは、懸濁物質を含む懸濁液を凝集反応槽の下方に設けた流入管からその内部に導くとともに、高分子凝集剤を凝集反応槽の下方から凝集反応槽に導いて旋回流を生じさせて凝集反応を起こさせ、凝集反応槽の上方に設けた流出管から槽外に排出されるよう構成したものである。 Conventionally, in water treatment and wastewater treatment, an inorganic or organic flocculant is injected into the agglomeration reactor together with the raw water (treated water) to be treated, and suspended or dissolved substances contained in the treated water are removed. Aggregation and removal as agglomerated flocs are performed.
As this type of apparatus, a vertical wet granulation apparatus is known (see, for example, Patent Document 1). This is because the suspension containing the suspended substance is introduced into the inside of the inflow pipe provided below the agglomeration reaction tank, and the polymer flocculant is introduced from below the agglomeration reaction tank to the agglomeration reaction tank to generate a swirl flow. The agglomeration reaction is caused to occur, and is discharged from the outflow pipe provided above the agglomeration reaction tank.

同様な凝集反応を起こさせる凝集装置も知られている（例えば、特許文献２を参照）。この凝集装置は、凝集反応槽内部に開口部を有する隔壁を複数多段に設け、かつ槽内部における生成フロックに接触ころがり運動を生起させるように回転円板を前記多段隔壁相互間で前記開口部を望むように配置して凝集反応槽の上方に設けられた開口部から原水を導くように構成したものである。
実開昭６０−２４４１１号公報特開昭４９−９７６４号公報 An aggregating apparatus that causes a similar agglutination reaction is also known (see, for example, Patent Document 2). In this aggregating apparatus, a plurality of partition walls having openings are provided in the agglomeration reaction tank in a plurality of stages, and a rotating disk is provided between the multi-stage partitions so as to cause contact rolling motion in the generated flock inside the tank. It arrange | positions as desired and it comprised so that raw | natural water might be guide | induced from the opening part provided above the coagulation reaction tank.

しかしながら、前記特許文献１に記載の竪型湿式造粒装置のように原水を凝集反応槽の下方から流入させる場合は、この凝集反応装置の次段に設けられる加圧浮上槽の混合室に原水を直接供給できないという問題がある。またこの装置は、原水が下方から凝集反応槽に導かれているため原水の状況を目視確認することが困難であるという問題もある。
この種の問題は、前述した特許文献２に記載の凝集装置によることで解決ができるものの凝集反応槽の上方から、この槽内に導かれる原水は、下向きの運動量を有しているため、隔壁によって多段構成された一段目にて十分な凝集処理ができないうちに二段目へ流入（短絡）して処理性能が低下するという新たな問題が生じる。 However, when the raw water is allowed to flow from below the agglomeration reaction tank as in the vertical wet granulation apparatus described in Patent Document 1, the raw water is fed into the mixing chamber of the pressurized flotation tank provided at the next stage of the agglomeration reaction apparatus. There is a problem that cannot be supplied directly. In addition, this apparatus has a problem that it is difficult to visually check the state of the raw water because the raw water is guided from below to the coagulation reaction tank.
Although this type of problem can be solved by using the aggregating apparatus described in Patent Document 2, the raw water introduced into the tank from above the agglomeration reaction tank has a downward momentum. As a result, a new problem arises in that the processing performance deteriorates due to inflow (short circuit) to the second stage before sufficient agglomeration processing cannot be performed in the first stage constituted by multiple stages.

本発明は、このような従来の事情を解決すべくなされたものであり、その目的とするところは、凝集反応槽内における原水の短絡を減少させて未凝集の懸濁物質（ＳＳ）の量を低減させて、該凝集反応装置の後段に位置する固液分離装置へ良好な処理水を提供することにある。 The present invention has been made to solve such a conventional situation, and the object of the present invention is to reduce the short circuit of raw water in the agglomeration reaction tank and to reduce the amount of unagglomerated suspended matter (SS). Is to provide good treated water to the solid-liquid separation device located in the subsequent stage of the agglomeration reaction device.

上述した目的を達成すべく本発明の凝集反応装置は、所定の配管により導かれた被処理水をその上方から受け入れるとともに、その下方から処理された前記被処理水を排出する水槽と、この水槽内に位置して、その内部を上下方向の複数の反応室にそれぞれ仕切る仕切り板と、前記仕切り板で仕切られた複数の反応室にそれぞれ導かれた前記被処理水をそれぞれ撹拌する複数の撹拌手段とを具備した凝集反応装置であって、特に
前記配管（原水導入管）は、前記水槽内の水平方向に前記被処理水を吐出させる吐出口を備えることを特徴としている。 In order to achieve the above-mentioned object, the agglomeration reaction apparatus of the present invention receives a water to be treated guided by a predetermined pipe from above, and discharges the water to be treated treated from below, and this water tank. A plurality of agitators, each of which is located inside and partitions the interior into a plurality of reaction chambers in the vertical direction, and each of the water to be treated guided to the plurality of reaction chambers partitioned by the partition plates. In particular, the pipe (raw water introduction pipe) is provided with a discharge port for discharging the water to be treated in a horizontal direction in the water tank.

好ましくは、前記仕切り板は、この仕切り板の略中心を通り、所定の幅に切り欠かれたスリットを備えることを特徴としている。
特に前記吐出口は、その開口部における中心位置の高さが前記水槽に蓄えられる前記被処理水の水面の高さに略等しいものとして構成される。
好ましくは、前記配管によって前記水槽内に導かれる前記被処理水の水面は、その配管の吐出口における開口部の高さに位置付けられることが望ましい。 Preferably, the partition plate includes a slit that passes through substantially the center of the partition plate and is notched to a predetermined width.
In particular, the discharge port is configured such that the height of the center position in the opening is substantially equal to the height of the water surface of the treated water stored in the water tank.
Preferably, the surface of the water to be treated guided into the water tank by the pipe is positioned at the height of the opening at the discharge port of the pipe.

上述の凝集反応装置は、原水（被処理水）をその槽の上方に位置付けられた反応槽に導き、下方に位置付けられた反応槽から凝集処理水を得る。また原水は、反応槽にこの原水を導く配管（原水導入管）によって凝集槽の上方から導かれた後、凝集槽内で水平方向に向きを変えた吐出口から排出される。この吐出口の中心位置の高さは凝集槽内で蓄えられる処理水の水面と略同じ高さに位置付けられ、上方の反応室における被処理水の凝集処理が不十分な状態で下方の反応室に直接流れ込む、いわゆる短絡を防ぐ。 The above-described flocculation reaction apparatus guides raw water (treated water) to a reaction tank positioned above the tank, and obtains flocculated water from the reaction tank positioned below. The raw water is guided from above the coagulation tank by a pipe (raw water introduction pipe) for guiding the raw water to the reaction tank, and then discharged from a discharge port whose direction is changed in the horizontal direction in the coagulation tank. The height of the central position of this discharge port is positioned at substantially the same level as the water level of the treated water stored in the coagulation tank, and the lower reaction chamber is in a state where the treatment water is not sufficiently coagulated in the upper reaction chamber. This prevents a so-called short circuit that flows directly into

また前記撹拌手段は、前記水槽における水平面の略中央の位置から垂直方向に延伸されて前記仕切り板を貫き、前記各反応室をそれぞれ貫通する棒体と、この棒体に取り付けられて、その長手方向を軸心として該棒体を回転駆動させる駆動部と、前記軸体にそれぞれに取り付けられて、前記軸体が貫通する前記反応室毎に前記棒体の軸心から前記水槽の壁面方向に延伸された板状の撹拌翼とを具備し、
隣り合う前記反応室の上流側に位置する該反応室は、下流側の前記反応室より少なくとも等しい枚数の前記撹拌翼を備えることを特徴としている。 Further, the stirring means extends vertically from a substantially central position of the horizontal plane in the water tank, penetrates the partition plate, and passes through the reaction chambers, and is attached to the rod body. A drive unit that rotationally drives the rod body with the direction as an axis, and a shaft attached to the shaft body and extending from the axis of the rod body to the wall surface direction of the water tank for each reaction chamber through which the shaft body passes. An elongated plate-shaped stirring blade,
The reaction chamber located on the upstream side of the adjacent reaction chambers includes at least the same number of the stirring blades as the downstream reaction chamber.

好ましくは、最上流の前記反応室に位置する前記撹拌手段は、四枚の前記撹拌翼が前記棒体の回転方向に対して互いに略９０度異なる位相差をなして該棒体に取り付けられることが望ましい。
より好ましくは最下流の前記反応室に位置する前記撹拌手段は、二枚の前記撹拌翼が前記棒体の回転方向に対して互いに略１８０度異なる位相差をなして該棒体に取り付けられることが望ましい。 Preferably, the stirring means located in the most upstream reaction chamber is configured such that the four stirring blades are attached to the rod body with a phase difference of approximately 90 degrees with respect to the rotation direction of the rod body. Is desirable.
More preferably, the agitation means located in the reaction chamber at the most downstream position is such that the two agitation blades are attached to the rod body with a phase difference of approximately 180 degrees relative to the rotation direction of the rod body. Is desirable.

上述の凝集反応装置は、原水が槽内に導かれる吐出口に近い反応室、つまり上方に位置する反応槽内の撹拌翼が下方の反応槽に設けられた撹拌翼より翼の枚数が多く、撹拌翼によって撹拌される被処理水に生じる乱流強度が大きい。一方、下方に位置する反応槽内には、上方の反応槽よりも翼の数が少ない撹拌翼が設けられているので、撹拌によって生じる被処理水の乱流強度が弱くなり緩速撹拌を行ったことと同様に作用する。このため被処理水に急速撹拌を行った後に、緩速撹拌を行ったことと同様に作用し、粒径が大きく良好な凝集フロックが生成される。 The agglomeration reaction apparatus described above has a larger number of blades than the agitation blades provided in the reaction chamber close to the discharge port through which the raw water is introduced into the vessel, that is, the reaction vessel located in the upper reaction vessel, The turbulent flow intensity generated in the water to be treated stirred by the stirring blade is large. On the other hand, in the reaction tank located at the lower side, a stirring blade having a smaller number of blades than the upper reaction tank is provided, so that the turbulent strength of the water to be treated generated by the stirring is weakened and the stirring is performed slowly. It works in the same way. For this reason, after carrying out rapid stirring to to-be-processed water, it acts similarly to having performed slow stirring, and a favorable aggregated floc with a large particle size is produced | generated.

また本発明の凝集反応装置は、この凝集反応装置に複数の前記仕切り板を備えるとき、これら仕切り板にそれぞれ設けられた前記スリットの延伸方向が前記仕切り板の上方または下方から視野したとき、互いに重ならない位置に設けられることを特徴としている。
好ましくは前記撹拌手段は、隣接する反応室にそれぞれ設けられた二枚の前記撹拌翼が前記棒体の回転方向に対して互いに略９０度異なる位相差をなして該棒体に取り付けられているとき、隣接する前記反応室にそれぞれ設けられた前記撹拌翼の延伸方向が互いに９０度の位相差をなして該棒体に取り付けられることが望ましい。 Moreover, when the aggregation reaction apparatus of the present invention includes a plurality of the partition plates in the aggregation reaction apparatus, when the extending directions of the slits respectively provided in the partition plates are viewed from above or below the partition plates, It is characterized by being provided at a position that does not overlap.
Preferably, the stirring means is attached to the rod body so that the two stirring blades respectively provided in adjacent reaction chambers have a phase difference of approximately 90 degrees with respect to the rotation direction of the rod body. At this time, it is desirable that the extending directions of the stirring blades provided in the adjacent reaction chambers are attached to the rod body with a phase difference of 90 degrees.

より好ましくは、前記スリットの短手方向の幅は、前記撹拌翼の厚みより略広く、かつ前記仕切り板における一辺の長さの２０％以下の長さであることが望ましい。
上述の凝集反応装置は、下方の反応室の被処理水が上方の反応室に逆流する、いわゆる逆混合や、上方の反応室における被処理水の凝集処理が不十分な状態で下方の反応室に流れ込む、いわゆる短絡が起こりにくく反応率が高くなる。このため本発明の凝集反応装置は、被処理水中における未凝集の懸濁物質（ＳＳ）等の量が減少し、処理水の水質を良好にさせる。 More preferably, the width of the slit in the short direction is substantially wider than the thickness of the stirring blade and is 20% or less of the length of one side of the partition plate.
The agglomeration reaction apparatus described above has a lower reaction chamber in a state where the water to be treated in the lower reaction chamber flows backward into the upper reaction chamber, so-called reverse mixing, or the water to be treated in the upper reaction chamber is insufficiently coagulated. The so-called short circuit that flows into the substrate hardly occurs and the reaction rate becomes high. For this reason, the amount of unaggregated suspended matter (SS) etc. in the to-be-processed water decreases, and the agglomeration reaction apparatus of this invention makes the quality of treated water good.

本発明の凝集反応装置によれば、原水（被処理水）を凝集槽内に導く配管（原水導入管）の端部に設けられた吐出口の中心位置の高さが凝集槽内で蓄えられる処理水の水面と略同じ高さに位置付けられているので、複数の反応室に仕切られた凝集反応槽内での短絡が起こりにくくなる原水の凝集処理率を向上させることができる。この吐出口は、凝集反応槽の上方に位置付けられているので、凝集反応槽内に流れ込む原水(被処理水)の状態を目視するが可能であり、また原水のサンプリングを容易に行うことができる。 According to the agglomeration reaction apparatus of the present invention, the height of the central position of the discharge port provided at the end of the pipe (raw water introduction pipe) for guiding the raw water (treated water) into the agglomeration tank is stored in the agglomeration tank. Since it is positioned at substantially the same height as the water surface of the treated water, it is possible to improve the coagulation treatment rate of the raw water that is less likely to cause a short circuit in the coagulation reaction tank partitioned by a plurality of reaction chambers. Since this discharge port is positioned above the agglomeration reaction tank, it is possible to visually check the state of the raw water (treated water) flowing into the agglomeration reaction tank, and the raw water can be easily sampled. .

また本発明の凝集反応装置は、複数の反応室を区画している仕切り板にスリットが設けられて、この仕切り板にて仕切られる直下の反応室内に設けられた撹拌翼の延伸方向と一致させるように設けられているので、撹拌翼をこのスリットを通して上方に引き上げることができる。したがって仕切り板を取り外すことなく撹拌翼を上方に引き上げることができるので、撹拌翼の取り外し、取り付け等のメンテナンスを容易に行うことができる。 In the agglomeration reaction apparatus of the present invention, a slit is provided in a partition plate that partitions a plurality of reaction chambers, and is made to coincide with the extending direction of the stirring blades provided in the reaction chamber directly under the partition plate. Therefore, the stirring blade can be pulled upward through this slit. Therefore, since the stirring blade can be pulled upward without removing the partition plate, maintenance such as removal and attachment of the stirring blade can be easily performed.

更に本発明の凝集反応装置は、仕切り板で仕切られた複数の反応室において、凝集反応槽の上方に位置する反応室に設けられた撹拌翼の枚数が下方に位置する反応室内の撹拌翼の枚数より多いので、上方に位置する反応室内の被処理水に生じる乱流強度が大きくなる。このため被処理水に急速撹拌を行った後に、緩速撹拌を行ったことと同様に作用し、粒径が大きく良好な凝集フロックを生成することができる。一方、下方に位置する反応室内は、上方の反応室よりも撹拌翼の枚数が少ないため、撹拌によって生じる被処理水の乱流強度が弱くなる。それ故、緩速撹拌と同様の効果を得ることができる。 Furthermore, in the agglomeration reaction apparatus of the present invention, in the plurality of reaction chambers partitioned by the partition plate, the number of the agitation blades provided in the reaction chamber located above the agglomeration reaction tank is reduced. Since the number is larger than the number, the turbulence intensity generated in the water to be treated in the reaction chamber located above is increased. For this reason, after performing rapid stirring to to-be-processed water, it acts similarly to having performed slow stirring, and can produce | generate a favorable aggregate floc with a large particle size. On the other hand, since the number of stirring blades is smaller in the reaction chamber located below than the upper reaction chamber, the turbulent flow strength of the water to be treated generated by stirring is weakened. Therefore, the same effect as the slow stirring can be obtained.

このように本発明の凝集反応装置は、被処理水中における未凝集の懸濁物質（ＳＳ）等の量を減少させ、後段の固液分離装置に導かれる処理水の質が良好になるという実用上多大なる効果を奏する。 As described above, the flocculation reaction apparatus of the present invention reduces the amount of unaggregated suspended matter (SS) and the like in the water to be treated, so that the quality of the treated water led to the subsequent solid-liquid separation apparatus is improved. There is a great effect.

以下、本発明の凝集反応装置の一実施形態について添付図面を参照しながら説明する。
図１〜図４は発明を実施する形態の一例であるが、これらの図は、本発明を説明するための図であって、これらの図によって本発明が限定されるものではない。
図１〜図４において１０は、凝集反応槽（水槽）である。この凝集反応槽１０には、その上方から凝集反応槽１０内に原水（被処理水）を導く配管（原水導入管）１が設けられている。そして凝集反応槽１０の下方には、この凝集反応槽１０内にて処理された被処理水を取り出して次段の加圧浮上装置３２へ排出する排出路２が設けられている。 Hereinafter, an embodiment of an agglutination reaction apparatus of the present invention will be described with reference to the accompanying drawings.
1 to 4 are examples of embodiments for carrying out the invention. However, these drawings are for explaining the present invention, and the present invention is not limited by these drawings.
1-4, 10 is an aggregation reaction tank (water tank). The agglomeration reaction tank 10 is provided with a pipe (raw water introduction pipe) 1 for introducing raw water (treated water) into the agglomeration reaction tank 10 from above. Under the agglomeration reaction tank 10, there is provided a discharge path 2 through which water to be treated that has been treated in the agglomeration reaction tank 10 is taken out and discharged to the pressurized flotation device 32 at the next stage.

原水導入管１は、凝集反応槽１０の上方から下向きに曲げられて、凝集反応槽１０内で水平向きになるように曲げられている（図３および図４（ａ）ＦＦ’断面を参照）。そしてその端部には、原水（被処理水）を凝集反応槽１０内に吐出させる吐出口１ａが設けられている。この吐出口１ａの開口部は、凝集反応槽１０内に導かれて、この凝集反応槽１０内において凝集処理中に蓄えられる被処理水の水面の位置と略等しい高さに位置付けられる。この開放部は、その中央部における位置の高さが被処理水の水面の位置と略等しい高さであることが望ましい（図４（ｂ）のＦＦ’断面の位置）。 The raw water introduction pipe 1 is bent downward from above the agglomeration reaction tank 10 and is bent in the horizontal direction in the agglomeration reaction tank 10 (refer to FIG. 3 and FIG. 4 (a) FF ′ cross section). . And the discharge port 1a which discharges raw | natural water (to-be-processed water) in the aggregation reaction tank 10 is provided in the edge part. The opening of the discharge port 1a is led into the agglomeration reaction tank 10 and is positioned in the agglomeration reaction tank 10 at a height substantially equal to the position of the water surface of the water to be treated stored during the agglomeration process. It is desirable that the height of the open portion at the center is substantially equal to the position of the water surface of the water to be treated (the position of the FF ′ cross section in FIG. 4B).

凝集反応槽１０は、この凝集反応槽１０の内部に位置して、凝集反応槽１０内を上下方向の複数の反応室１１にそれぞれ仕切る仕切り板１２を備える。この仕切り板１２には、この仕切り板１２の略中央を通り、所定の幅に切り欠かれたスリット１２ａが設けられている。このスリット１２ａは、仕切り板１２で仕切られた複数の反応室１１を連通して凝集反応槽１０に導かれた原水（被処理水）を上方の反応室１１から下方の反応室１１に導き、各反応室１１にて生じる短絡または逆混合を防ぐ役割を担う。このスリット１２ａは、凝集反応槽１０の幅の長さまたは奥行きの長さの２０％以下、好ましくは１５％以下の幅で、かつ後述する撹拌翼１３ｂの幅より１mm以上広いことが望ましい。 The agglomeration reaction tank 10 includes a partition plate 12 that is positioned inside the agglomeration reaction tank 10 and partitions the inside of the agglomeration reaction tank 10 into a plurality of reaction chambers 11 in the vertical direction. The partition plate 12 is provided with a slit 12a that passes through substantially the center of the partition plate 12 and is cut out to a predetermined width. The slit 12a communicates the plurality of reaction chambers 11 partitioned by the partition plate 12 and guides raw water (treated water) guided to the aggregation reaction tank 10 from the upper reaction chamber 11 to the lower reaction chamber 11. It plays the role which prevents the short circuit or reverse mixing which arises in each reaction chamber 11. FIG. The slit 12a is 20% or less, preferably 15% or less of the width or depth of the agglomeration reaction tank 10, and is desirably 1 mm or more wider than the width of a stirring blade 13b described later.

尚、凝集反応槽１０は、仕切り板１２の枚数を多くして多数の反応室１１を有する多段構成にするほど処理水の質が向上するものの構造が複雑になる。したがって凝集反応槽１０は、二枚の仕切り板１２を用いて三つの反応室１１の構成にすると構造が複雑にならず好ましい。
この仕切り板１２で仕切られた複数の反応室１１には、各反応室１１に導かれた被処理水を撹拌する複数の撹拌手段１３がそれぞれ設けられている。この撹拌手段１３は、凝集反応槽１０内に導かれて蓄えられる被処理水がなす水面の略中央の位置から垂直方向に延伸されて仕切り板１２を貫き、各反応室１１をそれぞれ貫通する棒体１３ａと、この棒体１３ａに取り付けられて、その長手方向を軸心として該棒体１３ａを回転駆動させる駆動部１４と、棒体１３ａにそれぞれ取り付けられて、前記棒体１３ａが貫通する反応室１１毎に棒体１３ａの軸心から凝集反応槽１０の壁面方向に延伸された板状の撹拌翼１３ｂを備える。 The agglomeration reaction tank 10 has a more complicated structure although the quality of treated water is improved as the number of partition plates 12 is increased and a multi-stage configuration having a large number of reaction chambers 11 is provided. Therefore, the agglomeration reaction tank 10 is preferably composed of three reaction chambers 11 using two partition plates 12 because the structure is not complicated.
The plurality of reaction chambers 11 partitioned by the partition plate 12 are respectively provided with a plurality of stirring means 13 for stirring the water to be treated guided to each reaction chamber 11. This stirring means 13 is a rod that extends vertically from the substantially central position of the water surface formed by the water to be treated that is guided and stored in the agglomeration reaction tank 10, penetrates the partition plate 12, and penetrates each reaction chamber 11. A body 13a, a drive unit 14 that is attached to the rod body 13a and rotationally drives the rod body 13a with the longitudinal direction as an axis, and a reaction that is attached to the rod body 13a and penetrates the rod body 13a. Each chamber 11 is provided with a plate-like stirring blade 13b extending from the axial center of the rod 13a toward the wall surface of the agglomeration reaction tank 10.

例えば凝集反応槽１０の高さが９５０mm、幅、奥行きとも８００mmであるとすれば、撹拌翼１３ｂの幅は、３１mm〜２００mm程度、好ましくは５０mm〜８０mmが望ましい。あるいは撹拌翼１３ｂの幅は、各反応室１１の高さに対して３％〜４０％程度、好ましくは８％〜３１％が望ましい。尚、撹拌翼１３ｂの厚みは、３mm〜１０mm程度、好ましくは４.５mm〜７mmが望ましい。 For example, if the agglomeration reaction tank 10 has a height of 950 mm and a width and a depth of 800 mm, the width of the stirring blade 13b is about 31 mm to 200 mm, preferably 50 mm to 80 mm. Alternatively, the width of the stirring blade 13b is about 3% to 40%, preferably 8% to 31% with respect to the height of each reaction chamber 11. The thickness of the stirring blade 13b is about 3 mm to 10 mm, preferably 4.5 mm to 7 mm.

また隣り合う反応室１１の上流側に位置する反応室１１は、下流側の反応室１１より少なくとも等しい枚数の撹拌翼１３ｂを備える。好ましくは上流側に位置する反応室１１ほど撹拌翼１３ｂの枚数を増やすことが望ましい。例えば、図２に示すように凝集反応槽１０を二枚の仕切り板１２によって三つの反応室１１を備える構成とした場合、最も上流側（初段）の反応室１１には、四枚の撹拌翼１３ｂを備えた撹拌手段１３とし、次段（第二段）および終段の反応室１１には、それぞれ二枚の撹拌翼１３ｂの構成とする。 Further, the reaction chamber 11 located on the upstream side of the adjacent reaction chambers 11 is provided with at least an equal number of stirring blades 13b than the downstream reaction chambers 11. Preferably, the number of the stirring blades 13b is increased in the reaction chamber 11 located on the upstream side. For example, as shown in FIG. 2, when the agglomeration reaction tank 10 includes three reaction chambers 11 with two partition plates 12, the most upstream (first stage) reaction chamber 11 includes four stirring blades. The stirring means 13 is provided with 13b, and the next-stage (second stage) and final-stage reaction chambers 11 each have two stirring blades 13b.

このように上流側に位置する反応室１１の撹拌翼１３ｂの枚数を増やして、上流側ほど被処理水に与える乱流強度を大きくする一方、下流側の被処理水に与える乱流強度を弱くする。
尚、初段の反応室１１が四枚の撹拌翼１３ｂを備える場合、棒体１３ａの回転方向に対して互いに略９０度異なる位相差をなして取り付けることが望ましい。 In this way, by increasing the number of the stirring blades 13b of the reaction chamber 11 located on the upstream side, the turbulent strength given to the water to be treated is increased toward the upstream side, while the turbulent strength given to the water to be treated on the downstream side is weakened. To do.
In addition, when the first-stage reaction chamber 11 includes four stirring blades 13b, it is desirable that the reaction chambers 11 be attached with a phase difference of approximately 90 degrees with respect to the rotation direction of the rod 13a.

また下流の反応室に位置する撹拌手段１３が、二枚の撹拌翼１３ｂを備える場合、棒体１３ａの回転方向に対して互いに略１８０度異なる位相差をなして取り付けることが好ましい。
特に図２に示すように第二段および終段の反応室１１がそれぞれ備える撹拌手段１３は、各反応室１１にそれぞれ設けられた二枚の撹拌翼１３ｂが棒体１３ａの回転方向に対して互いに略１８０度異なる位相差をなして棒体１３ａに取り付けられているとき、隣接する反応室１１にそれぞれ設けられた撹拌翼１３ｂの延伸方向が互いに９０度の位相差をなすよう棒体１３ａに取り付ける。 Moreover, when the stirring means 13 located in the downstream reaction chamber is provided with two stirring blades 13b, it is preferable to attach the stirring means 13 with a phase difference of approximately 180 degrees with respect to the rotation direction of the rod body 13a.
In particular, as shown in FIG. 2, the stirring means 13 provided in each of the second-stage and final-stage reaction chambers 11 includes two stirring blades 13b provided in each reaction chamber 11, respectively, with respect to the rotation direction of the rod 13a. When attached to the rod body 13a with a phase difference of about 180 degrees different from each other, the extension direction of the stirring blades 13b respectively provided in the adjacent reaction chambers 11 forms a phase difference of 90 degrees with the rod body 13a. Install.

しかして第二段以降の下流側に位置する反応室１１がそれぞれ備える撹拌翼１３ｂは、撹拌翼の取り外し、取り付け等のメンテナンスを容易にできるようにするため、各反応室１１のスリット１２ａの位置を隣接する反応室１１にそれぞれ設けられた撹拌翼１３ｂの延伸方向と一致するように設ける。具体的には、図３に示すように第二段および最終段のそれぞれの反応室１１に設けられた撹拌翼１３ｂが互いに９０度の位相差をなすよう棒体１３ａに取り付けられているとすれば（図３および図４（ｃ）のＣＣ’断面および図４（ｇ）ＥＥ’断面を参照）、各仕切り板１２にそれぞれ設けられたスリット１２ａも互いに９０度の位相差を有するように凝集反応槽１０内に取り付ける（図３および図４（ｄ）のＢＢ’断面および図４（ｇ）ＤＤ’断面を参照）。 Therefore, the stirring blades 13b provided in the reaction chambers 11 located downstream of the second stage and the subsequent stages are provided with positions of the slits 12a of the reaction chambers 11 in order to facilitate maintenance such as removal and attachment of the stirring blades. Are provided so as to coincide with the extending direction of the stirring blades 13b provided in the adjacent reaction chambers 11 respectively. Specifically, as shown in FIG. 3, it is assumed that the stirring blades 13b provided in the reaction chambers 11 of the second stage and the final stage are attached to the rod body 13a so as to form a phase difference of 90 degrees. 3 (see the CC ′ cross section of FIG. 3 and FIG. 4C and the cross section of FIG. 4G EE ′), the slits 12a provided in each partition plate 12 also aggregate so as to have a phase difference of 90 degrees from each other. It is installed in the reaction vessel 10 (see the BB ′ cross section and FIG. 4 (g) DD ′ cross section in FIGS. 3 and 4D).

また前述した原水導入管１および吐出口１ａの取り付け位置は、凝集反応槽１０を上方から視野した図４（ｃ）の断面ＦＦ’に示すように撹拌翼１３ｂが、この図において時計回りに回転する旋回流が生じる場合、撹拌翼１３ｂによる旋回流の接線方向と一致するようにして原水が吐出口１ａから凝集反応槽１０内に吐出されるようにする。
尚、上述した凝集反応槽１０は、直方体形状として説明したものであるが、水平面の断面が円形または楕円形状等の円筒形状であってもよい（特に図示せず）。その場合は前述した仕切り板１２を凝集反応槽１０の断面形状に一致させて複数の反応室１１が形成されるようにすると共に、仕切り板１２にスリット１２ａを設ければよい。もちろんこの場合は、撹拌翼１３ｂが回転するとき凝集反応槽１０の壁面に接触することなく回動できるようにすることは言うまでもない。 In addition, the mounting position of the raw water introduction pipe 1 and the discharge port 1a described above is such that the stirring blade 13b rotates clockwise in this figure as shown in the cross-section FF ′ in FIG. When the swirling flow is generated, the raw water is discharged into the agglomeration reaction tank 10 from the discharge port 1a so as to coincide with the tangential direction of the swirling flow by the stirring blade 13b.
In addition, although the aggregation reaction tank 10 mentioned above was demonstrated as a rectangular parallelepiped shape, the cross section of a horizontal surface may be cylindrical shapes, such as circular or elliptical shape (not shown in particular). In that case, the partition plate 12 described above is matched with the cross-sectional shape of the agglomeration reaction tank 10 so that a plurality of reaction chambers 11 are formed, and the partition plate 12 may be provided with slits 12a. Of course, in this case, it goes without saying that the stirring blade 13b can be rotated without contacting the wall surface of the agglomeration reaction tank 10 when rotating.

ちなみに吐出口１ａの下流側、すなわち旋回流の下流側には、詳細は述べないが凝集反応槽１０内に導かれた原水に凝集反応を起こさせる凝集剤を投入する凝集剤投入口２０、凝集反応槽１０内で凝集反応を起こしている被処理水のｐＨを計測するｐＨセンサ２１、このｐＨセンサ２１が検出したｐＨ値を測定するｐＨ測定装置２２、ｐＨ測定装置２２が検出したｐＨ値が適切なｐＨ値になるようにアルカリ薬剤および酸性薬剤を凝集反応槽１０内にそれぞれ投入するアルカリ剤投入口２３および酸性剤投入口２４を備える。尚、凝集剤投入口２０から投入される凝集剤は、凝集剤を蓄えるＰＡＣタンク２５に保持されて、凝集制御装置の制御部２６から凝集ポンプ２７が駆動されて凝集反応槽１０に注入される薬注量が制御される。また、凝集反応槽１０内のｐＨ値を所定の値にするため、ｐＨ測定装置２２が測定したｐＨ値は、制御部２６に与えられて、凝集反応槽１０内のｐＨ値を調整するアルカリ性薬液および酸性薬液（塩酸）を蓄えるアルカリ剤タンク２８および塩酸タンク２９にそれぞれ保持されて、制御部２６からアルカリ剤注入ポンプ３０または塩酸注入ポンプ３１が選択駆動されて凝集反応槽１０に薬液が注入されてｐＨ値の調整がなされる。 Incidentally, on the downstream side of the discharge port 1a, that is, on the downstream side of the swirling flow, although not described in detail, a flocculant inlet 20 for introducing a flocculant that causes agglomeration reaction to the raw water introduced into the agglomeration reaction tank 10, A pH sensor 21 that measures the pH of the water to be treated in the reaction tank 10 that undergoes agglutination reaction, a pH measurement device 22 that measures the pH value detected by the pH sensor 21, and a pH value detected by the pH measurement device 22 are An alkaline agent inlet 23 and an acidic agent inlet 24 are provided for introducing an alkaline agent and an acidic agent into the agglomeration reaction tank 10 so as to obtain an appropriate pH value. The flocculant charged from the flocculant charging port 20 is held in a PAC tank 25 that stores the flocculant, and the flocculant pump 27 is driven from the control unit 26 of the flocculant control device to be injected into the flocculant reaction tank 10. The dosage is controlled. Further, in order to set the pH value in the agglutination reaction tank 10 to a predetermined value, the pH value measured by the pH measuring device 22 is given to the control unit 26 to adjust the pH value in the agglomeration reaction tank 10. And the alkaline agent tank 28 and the hydrochloric acid tank 29 for storing acidic chemical solution (hydrochloric acid), respectively, and the alkaline agent injection pump 30 or hydrochloric acid injection pump 31 is selectively driven from the control unit 26 to inject the chemical solution into the agglomeration reaction tank 10. The pH value is adjusted.

このように構成された本発明の凝集反応槽１０の次段には、加圧浮上装置３２が接続される。この加圧浮上装置３２は、本発明の凝集反応装置とは異なるため略述するが凝集反応槽１０にて凝集反応された被処理水に含まれるフロックを分離する役割を担っている。この加圧浮上装置３２は、槽内に蓄えられた処理水を取り出して、空気を混入させて高圧の加圧水を生成して凝集反応槽１０と加圧浮上装置３２とを連結する排出路２に気液混合流を送り込む加圧水製造装置３３を備える。 A pressure levitation device 32 is connected to the next stage of the agglomeration reaction tank 10 of the present invention configured as described above. Although this pressurized levitation device 32 is different from the agglomeration reaction device of the present invention, it will be briefly described, but plays a role of separating flocs contained in the water to be treated that has undergone agglomeration reaction in the agglomeration reaction tank 10. The pressurized levitation device 32 takes out the treated water stored in the tank, mixes air to generate high-pressure pressurized water, and connects the agglomeration reaction tank 10 and the pressurized levitation device 32 to the discharge path 2. A pressurized water production apparatus 33 for feeding the gas-liquid mixed flow is provided.

そして前段の凝集反応装置にて凝集反応がなされた被処理水に含まれる水の比重より小さいフロック（スカム等）は、加圧浮上装置３２に蓄えられる被処理水の水面近傍に位置付けられたスカム取出し装置３４によって槽外へ排出され、浮上スラッジとして排出される。一方、加圧浮上装置に導かれた被処理水に含まれる比重の大きなスラッジは、沈降スラッジとして槽外に排出される。 A flock (such as scum) smaller than the specific gravity of water contained in the water to be treated that has undergone agglomeration reaction in the preceding agglomeration reactor is a scum positioned in the vicinity of the water surface of the water to be treated stored in the pressurized levitation device 32 It is discharged out of the tank by the take-out device 34 and discharged as floating sludge. On the other hand, sludge having a large specific gravity contained in the water to be treated guided to the pressurized levitation device is discharged out of the tank as sedimentation sludge.

しかして加圧浮上装置３２にてスラッジが取り出された処理水は、次段の水位調整装置４０にて水位が調整されて後工程へ送られる。
かくして上述したように構成された本発明の凝集反応装置によれば、凝集反応槽１０内に原水（被処理水）を導く配管（原水導入管１）を介してその上方から該原水を受け入れ、原水導入管１の端部に設けられた吐出口１ａから凝集反応槽１０内の水平方向に前記被処理水を吐出させると共に、スリット１２ａを備える複数の仕切り板１２によって槽内に複数の反応室１１を設けているので、凝集反応槽１０内での反応が多段反応となり原水の凝集処理率を向上させることが可能である。また吐出口１ａは、凝集反応槽１０の上方に位置付けられているので、凝集反応槽１０内に流れ込む原水(被処理水)の状態を目視するが可能であり、また原水のサンプリングを容易に行うことも可能である。 Thus, the treated water from which the sludge has been taken out by the pressurized flotation device 32 is adjusted in the water level by the water level adjustment device 40 in the next stage and sent to the subsequent process.
Thus, according to the flocculation reaction apparatus of the present invention configured as described above, the raw water is received from above through the pipe (raw water introduction pipe 1) for introducing the raw water (treated water) into the flocculation reaction tank 10, The treated water is discharged in the horizontal direction in the agglomeration reaction tank 10 from the discharge port 1a provided at the end of the raw water introduction pipe 1, and a plurality of reaction chambers are provided in the tank by a plurality of partition plates 12 having slits 12a. 11 is provided, the reaction in the flocculation reaction tank 10 becomes a multistage reaction, and the flocculation treatment rate of the raw water can be improved. Further, since the discharge port 1a is positioned above the agglomeration reaction tank 10, the state of raw water (treated water) flowing into the agglomeration reaction tank 10 can be visually observed, and the raw water is easily sampled. It is also possible.

また凝集反応槽１０は、複数の反応室１１を区画する仕切り板１２にそれぞれスリット１２ａが設けられて、このスリット１２ａの切り欠き方向が、この仕切り板１２にて仕切られる直下の反応室１１内に設けられた撹拌翼１３ｂの延伸方向と一致するようにして設けられているので、撹拌翼１３ｂをこのスリット１２ａを通して上方に引き上げることができる。したがって仕切り板１２を取り外すことなく撹拌手段１３を上方に引き上げることができるので、撹拌翼１３ｂの取り外し、取り付け等のメンテナンスを容易に行うことができる。 In the agglomeration reaction tank 10, slits 12 a are respectively provided in partition plates 12 that partition a plurality of reaction chambers 11, and the notch direction of the slits 12 a is within the reaction chamber 11 immediately below that is partitioned by the partition plates 12. Is provided so as to coincide with the extending direction of the agitating blade 13b provided in the above, so that the agitating blade 13b can be pulled upward through the slit 12a. Therefore, since the stirring means 13 can be pulled upward without removing the partition plate 12, maintenance such as removal and attachment of the stirring blade 13b can be easily performed.

特に本発明の凝集反応装置は、仕切り板１２で仕切られた複数の反応室１１において、凝集反応槽１０の上方に位置する該凝集反応槽１０に設けられた撹拌翼１３ｂの枚数が下方に位置する反応室１１内の撹拌翼１３ｂの枚数より多いので、上方に位置する反応室１１内の被処理水に生じる乱流強度が大きくなる。
また下方に位置する反応室１１内では、上方の反応室１１よりも撹拌翼の枚数が少ないため、撹拌によって生じる被処理水の乱流強度が弱くなり、緩速撹拌と同様の効果を得ることができる。このため、被処理水に急速撹拌を行った後に、緩速撹拌を行ったことと同様に作用する。それ故、粒径が大きく良好な凝集フロックを得ることができる。 Particularly, in the agglomeration reaction apparatus of the present invention, in the plurality of reaction chambers 11 partitioned by the partition plate 12, the number of the stirring blades 13b provided in the agglomeration reaction tank 10 located above the agglomeration reaction tank 10 is positioned below. Since there are more than the number of stirring blades 13b in the reaction chamber 11, the turbulence intensity generated in the water to be treated in the reaction chamber 11 located above is increased.
Further, in the reaction chamber 11 located below, since the number of stirring blades is smaller than that of the upper reaction chamber 11, the turbulent strength of the water to be treated generated by stirring is weakened, and the same effect as that of the slow stirring is obtained. Can do. For this reason, after performing rapid stirring to to-be-processed water, it acts similarly to having performed slow stirring. Therefore, a good aggregate floc having a large particle size can be obtained.

このように本発明の凝集反応装置は、被処理水中における未凝集の懸濁物質（ＳＳ）等の量を減少させ、後段の固液分離装置に導かれる処理水の質を良好にすることができる。
尚、本発明の凝集反応装置は、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることが可能である。 As described above, the agglomeration reaction apparatus of the present invention can reduce the amount of unaggregated suspended matter (SS) and the like in the water to be treated, and improve the quality of the treated water led to the solid-liquid separation apparatus in the subsequent stage. it can.
The agglutination reaction apparatus of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
