次に図面を参照して、本発明の好ましい実施の形態に係る水処理装置について詳細に説明する。図１は、本発明の好ましい実施の形態に係る水処理装置の全体を示した斜視図、図２（ａ）は、図１の線２ａ−２ａに沿って見た断面図である。図１において全体として参照符号１０で示される本発明の好ましい実施の形態に係る水処理装置は大別して、攪拌槽１２と、第１沈殿槽３０と、第２沈殿槽４０の３つの部分に分けられる。 Next, with reference to the drawings, a water treatment apparatus according to a preferred embodiment of the present invention will be described in detail. FIG. 1 is a perspective view showing an entire water treatment apparatus according to a preferred embodiment of the present invention, and FIG. 2A is a cross-sectional view taken along line 2a-2a in FIG. 1, the water treatment apparatus according to a preferred embodiment of the present invention generally indicated by reference numeral 10 is roughly divided into three parts: a stirring tank 12, a first settling tank 30, and a second settling tank 40. It is done.

水処理装置１０の攪拌槽１２は、全体として箱型の形状を有しており、平面的にほぼ中央の箇所に配置された攪拌装置１４を備えている。攪拌装置１４は、垂直方向に延びたシャフト１４ａと、シャフト１４ａの下端に固定された攪拌用羽根１４ｂと、シャフト１４ａを回転させるためのモータ１４ｃとを有している。 The agitation tank 12 of the water treatment apparatus 10 has a box-like shape as a whole, and includes an agitation apparatus 14 disposed at a substantially central position in plan view. The stirring device 14 includes a shaft 14a extending in the vertical direction, a stirring blade 14b fixed to the lower end of the shaft 14a, and a motor 14c for rotating the shaft 14a.

攪拌槽１２は又、攪拌装置１４のモータ１４ｃを覆うように配置され、下端が開放した円筒管１６を備えている。円筒管１６の側壁には、多数の貫通孔１６ａが設けられている。円筒管１６は、その下端が攪拌用羽根１４ｂより上方に位置するように（換言すると、攪拌用羽根１４ｂが円筒管１６の下端から突出するように）配置されている。 The agitation tank 12 is also provided with a cylindrical tube 16 which is disposed so as to cover the motor 14c of the agitation device 14 and whose lower end is opened. A large number of through holes 16 a are provided on the side wall of the cylindrical tube 16. The cylindrical tube 16 is arranged so that the lower end thereof is located above the stirring blade 14b (in other words, the stirring blade 14b protrudes from the lower end of the cylindrical tube 16).

以上の構成により、処理しようとする汚水や排水等（以下「被処理水」という）を攪拌槽１２に投入し、攪拌装置１４を作動させると、攪拌用羽根１４ｂの回転によって、被処理水が下方に差し向けられ、底壁に当たって被処理水が上昇し、円筒管１６の各貫通孔１６ａから円筒管１６内にそれぞれ吸い込まれるので、図２において矢印で示されるように、攪拌槽１２内で下方から上方に向かって流れる水流が発生し、被処理水の攪拌が効率的に行われる。とりわけ、攪拌槽１２内の上方の箇所から中程の箇所にかけて多数の貫通孔１６ａを設けたことにより、円筒管１６の高さ全体にわたって被処理水が吸引され、これにより攪拌槽１２全体で被処理水の攪拌が行われるようになっている。なお、円筒管１６は、上述のように、被処理水をその高さ全体にわたって貫通孔１６ａを介して吸引する機能を有するとともに、攪拌装置１４を支持具（図示せず）を介して支持する機能をも有する。 With the above configuration, when sewage or drainage to be treated (hereinafter referred to as “treated water”) is put into the agitation tank 12 and the agitation device 14 is operated, the agitation blade 14 b rotates to Since the water to be treated is directed downward and hits the bottom wall and is sucked into the cylindrical tube 16 from each through hole 16a of the cylindrical tube 16, as shown by the arrow in FIG. A water flow that flows from the bottom to the top is generated, and the water to be treated is efficiently stirred. In particular, by providing a large number of through-holes 16 a from the upper part to the middle part in the stirring tank 12, the water to be treated is sucked over the entire height of the cylindrical tube 16. The treated water is agitated. In addition, as described above, the cylindrical tube 16 has a function of sucking the water to be treated over the entire height through the through hole 16a and supports the stirring device 14 via a support (not shown). It also has a function.

攪拌槽１２の側壁には、攪拌用羽根１４ｂのほぼ同じ高さのところに、被処理水投入管１８が配置されている。被処理水投入管１８に隣接した攪拌槽１２の内部には、被処理水投入路２０が形成されている。被処理水投入路２０は、被処理水投入管１８と連通した被処理水投入口２０ａと、攪拌装置１４の攪拌用羽根１４ｂのほぼ側方に位置決めされた被処理水排出口２０ｂとを有しており、被処理水投入口２０ａの位置する箇所と被処理水排出口２０ｂの位置する箇所とを隔て、上端に連通部２０ｃ１が設けられた垂直隔壁２０ｃによって、被処理水投入路２０の内部が第１部分２０ｄと第２部分２０ｅとに分割されている（図２（ａ）参照）。被処理水排出口２０ｂは、攪拌用羽根１４ｂの近傍の箇所にのみ被処理水を排出して被処理水を攪拌槽１２内の下方に効率的に差し向けることができるように、上述のように、攪拌用羽根１４ｂのほぼ側方の高さの箇所にできるだけ幅狭となるように形成されている（図２（ｂ）参照）。なお、被処理水排出口２０ｂは、幅狭となる条件を満たすものであれば、図２（ｂ）のような円形でなく他の任意の形状（例えば、矩形）に形成してもよい。 On the side wall of the agitation tank 12, a to-be-treated water input pipe 18 is disposed at substantially the same height as the agitation blade 14 b. A treated water charging path 20 is formed inside the agitation tank 12 adjacent to the treated water charging pipe 18. The to-be-treated water input path 20 has a to-be-treated water input port 20 a communicating with the to-be-treated water input pipe 18 and a to-be-processed water discharge port 20 b positioned substantially laterally of the stirring blade 14 b of the stirring device 14. In addition, the vertical partition 20c provided with a communication portion 20c1 at the upper end is separated from the location where the treated water inlet 20a is located and the location where the treated water outlet 20b is located. The inside is divided into a first portion 20d and a second portion 20e (see FIG. 2A). The treated water discharge port 20b discharges the treated water only to the vicinity of the stirring blade 14b so that the treated water can be efficiently directed downward in the stirring tank 12 as described above. In addition, the stirrer blade 14b is formed to be as narrow as possible at a substantially lateral height (see FIG. 2B). In addition, as long as the to-be-processed water discharge port 20b satisfy | fills the conditions which become narrow, you may form in other arbitrary shapes (for example, rectangle) instead of a circle like FIG.2 (b).

攪拌槽１２は又、被処理水投入路２０の第２部分２０ｅ内に水処理剤を投入するための水処理剤投入機２２を備えている。水処理剤投入機２２によって投入される水処理剤は、公知のものを使用してよい。 The agitation tank 12 is also provided with a water treatment agent dispenser 22 for introducing a water treatment agent into the second portion 20 e of the water to be treated introduction path 20. A known water treatment agent may be used as the water treatment agent introduced by the water treatment agent feeder 22.

好ましくは、水処理剤投入機２２には、水処理剤落下促進機構２４が設置されている。図３は、水処理剤落下促進機構２４を示した斜視図である。水処理剤落下促進機構２４は、モータ２４ｄによって回転駆動されるシャフト２４ａと、シャフト２４ａから放射状に延びるようにシャフト２４ａに取り付けられた複数のアーム２４ｂと、下端がアーム２４ｂに接触するように配置された板バネ２４ｃとを有している。 Preferably, the water treatment agent dropping machine 22 is provided with a water treatment agent dropping promotion mechanism 24. FIG. 3 is a perspective view showing the water treatment agent dropping promotion mechanism 24. The water treatment agent dropping promotion mechanism 24 is arranged so that a shaft 24a rotated by a motor 24d, a plurality of arms 24b attached to the shaft 24a so as to extend radially from the shaft 24a, and a lower end thereof in contact with the arm 24b. Plate spring 24c.

図４は、水処理剤落下促進機構２４の一連の作動状態を示した図である。図４（ａ）に示す状態では、アーム２４ｂが板バネ２４ｃの下端に接触している。シャフト２４ａが更に回転すると、板バネ２４ｃは接触しているアーム２４ｂによって撓まされる（図４（ｂ）参照）。次いで、シャフト２４ａが更に回転すると、アーム２４ｂと板バネ２４ｃとの接触が外れ、板バネ２４ｃは次位置のアーム２４ｂまで移動する（図４（ｃ）参照）。この際、板バネ２４ｃと次位置のアーム２４ｂとの衝突により生ずる衝撃力により、水処理剤に衝撃が加えられ、水処理剤の落下が促進される。 FIG. 4 is a diagram showing a series of operating states of the water treatment agent dropping promotion mechanism 24. In the state shown in FIG. 4A, the arm 24b is in contact with the lower end of the leaf spring 24c. When the shaft 24a further rotates, the leaf spring 24c is bent by the contacting arm 24b (see FIG. 4B). Next, when the shaft 24a further rotates, the contact between the arm 24b and the leaf spring 24c is released, and the leaf spring 24c moves to the arm 24b at the next position (see FIG. 4C). At this time, an impact is applied to the water treatment agent by the impact force generated by the collision between the leaf spring 24c and the arm 24b at the next position, and the fall of the water treatment agent is promoted.

水処理装置１０の第１沈殿槽３０は、全体として箱型の形状を有し、下部分３０ａが逆円錐形状又は逆角錐形状に形作られている。 The first settling tank 30 of the water treatment apparatus 10 has a box shape as a whole, and the lower portion 30a is formed in an inverted cone shape or an inverted pyramid shape.

図５は、水処理装置１０の平面図である。攪拌槽１２と第１沈殿槽３０との間には、攪拌槽１２と第１沈殿槽３０とを連通させる連通路３２が配置されている。連通路３２は、攪拌槽１２の第１沈殿槽３０側の側壁に攪拌槽１２の上部から垂直方向下方に延びるように配置された流入口３２ａと、第１沈殿槽３０の隅部において（図５参照）第１沈殿槽３０の高さのほぼ中程の箇所から斜め下方に延びるように配置された（図２参照）流出口３２ｂとを有している。流出口３２ｂは、第１沈殿槽３０の外壁に沿って延びた管部材で形成されており、これにより流出口３２ｂから流出した被処理水が、第１沈殿槽３０内に流出して下部分３０ａの壁面に当たるとともに、沈殿槽３０内で旋回流となるように構成されている（図５参照）。このように構成することにより、下部分３０ａの壁面に付着した沈降物を洗い落とすことができるとともに、旋回流とすることによって被処理水中の凝集物同士を付着させて沈降し易くすることができるという効果を得ることができる。 FIG. 5 is a plan view of the water treatment apparatus 10. Between the agitation tank 12 and the first precipitation tank 30, a communication path 32 that connects the agitation tank 12 and the first precipitation tank 30 is disposed. The communication path 32 is formed at the inlet 32a disposed on the side wall of the stirring tank 12 on the first precipitation tank 30 side so as to extend vertically downward from the upper part of the stirring tank 12, and at the corner of the first precipitation tank 30 (see FIG. 5) and an outflow port 32b (see FIG. 2) arranged so as to extend obliquely downward from an approximately middle position of the height of the first sedimentation tank 30 (see FIG. 2). The outflow port 32b is formed of a pipe member extending along the outer wall of the first settling tank 30, and thereby, the water to be treated flowing out from the outflow port 32b flows into the first settling tank 30 and the lower part. It is configured to hit the wall surface of 30a and to be a swirling flow in the settling tank 30 (see FIG. 5). By comprising in this way, while being able to wash away the sediment adhering to the wall surface of the lower part 30a, it can be made easy to settle by adhering the aggregates in to-be-processed water by setting it as a swirl flow. An effect can be obtained.

水処理装置１０の第２沈殿槽４０も、第１沈殿槽３０と同様に、全体として箱型の形状を有し、下部分４０ａが逆円錐形状又は逆角錐形状に形作られている。第１沈殿槽３０と第２沈殿槽４０との間には、第１沈殿槽３０と第２沈殿槽４０とを連通させる連通路４２が配置されている。連通路４２は、連通路３２と同様に、第１沈殿槽３０の第２沈殿槽４０側の側壁に第１沈殿槽３０の上部から垂直方向下方に延びるように配置された流入口４２ａと、第２沈殿槽４０の隅部において（図５参照）第２沈殿槽４０の高さのほぼ中程の箇所から斜め下方に延びるように配置された（図２参照）流出口４２ｂとを有している。流出口４２ｂは、第２沈殿槽４０の外壁に沿って延びた管部材で形成されており、これにより流出口４２ｂから流出した被処理水が、第２沈殿槽４０内に流出して下部分４０ａの壁面に当たるとともに、沈殿槽４０内で旋回流となるように構成されている（図５参照）。これにより、沈殿槽３０の場合と同様に、下部分４０ａの壁面の付着物の洗い落としと凝集物の沈降を容易にするという効果が得られる。 Similarly to the first sedimentation tank 30, the second sedimentation tank 40 of the water treatment apparatus 10 has a box shape as a whole, and the lower portion 40a is formed in an inverted cone shape or an inverted pyramid shape. Between the 1st sedimentation tank 30 and the 2nd sedimentation tank 40, the communication path 42 which connects the 1st sedimentation tank 30 and the 2nd sedimentation tank 40 is arrange | positioned. Similarly to the communication path 32, the communication path 42 has an inflow port 42a disposed on the side wall of the first settling tank 30 on the second settling tank 40 side so as to extend vertically downward from the upper part of the first settling tank 30; In the corner of the second sedimentation tank 40 (see FIG. 5), an outlet 42b is disposed so as to extend obliquely downward (see FIG. 2) from a substantially middle position of the second sedimentation tank 40 (see FIG. 2). ing. The outflow port 42b is formed by a pipe member extending along the outer wall of the second settling tank 40, whereby the water to be treated flowing out from the outflow port 42b flows into the second settling tank 40 and is the lower part. While hitting the wall surface of 40a, it is comprised so that it may become a swirl flow within the sedimentation tank 40 (refer FIG. 5). Thereby, similarly to the case of the sedimentation tank 30, the effect of facilitating washing off the deposits on the wall surface of the lower portion 40a and sedimentation of the aggregates can be obtained.

第２沈殿槽４０の第１沈殿槽３０が位置する側と反対側の側壁には、本装置によって処理水を排出させるための排出口５０が配置されている（図１参照）。 On the side wall of the second settling tank 40 opposite to the side where the first settling tank 30 is located, a discharge port 50 for discharging treated water by this apparatus is arranged (see FIG. 1).

好ましくは、第１沈殿槽３０の第２沈殿槽４０の両方又はいずれか一方に、沈殿槽の底部に溜まった沈殿物を洗い流すための洗浄機構３４が設けられている（図６（ａ）参照）。洗浄機構３４は、沈殿槽３０、４０の底部に沿って配置された洗浄管３４ａと、洗浄管３４ａに洗浄水を供給するための給水管３４ｂと、給水管３４ｂに洗浄水を圧送するためのポンプ３４ｃとを有しており、洗浄管３４ａの底部および両側部には、多数の貫通孔３４ａ１が設けられている。これにより、洗浄管３４ａに水を圧送することにより、貫通孔３４ａ１から沈殿槽３０、４０の底部に向かって洗浄水が噴射され、沈殿槽３０、４０の底部に溜まった沈殿物が洗い流されるようになっている。 Preferably, a cleaning mechanism 34 is provided in both or any one of the second settling tanks 40 of the first settling tank 30 to wash out the sediment accumulated at the bottom of the settling tank (see FIG. 6A). ). The cleaning mechanism 34 includes a cleaning pipe 34a disposed along the bottom of the settling tanks 30 and 40, a water supply pipe 34b for supplying cleaning water to the cleaning pipe 34a, and a pump for supplying the cleaning water to the water supply pipe 34b. And a plurality of through holes 34a1 are provided at the bottom and both sides of the cleaning pipe 34a. Thereby, by pumping water to the washing pipe 34a, washing water is jetted from the through-hole 34a1 toward the bottom of the settling tanks 30 and 40, and the sediment accumulated at the bottom of the settling tanks 30 and 40 is washed away. It has become.

次に、以上のように構成された水処理装置１０の作動について説明する。図２に示されるように、被処理水投入管１８から攪拌槽１２内に投入された被処理水は、被処理水投入口２０ａを通り、垂直隔壁２０ｃを越流して被処理水投入路２０の第２部分２０ｅに落下する。その際、第２部分２０ｅ内に水処理剤が投下されるので、越流して落下する被処理水に水処理剤が効果的に混合される。なお、水処理剤投入機２２内に水処理剤落下促進機構２４が設置されている場合には、湿気により水処理剤が落下しにくくなる等の事態を回避し、水処理剤を円滑に落下させることができる。 Next, the operation of the water treatment apparatus 10 configured as described above will be described. As shown in FIG. 2, the water to be treated introduced into the agitation tank 12 from the water to be treated feeding pipe 18 passes through the water to be treated inlet 20 a and overflows the vertical partition wall 20 c to enter the water to be treated input path 20. The second part 20e falls. At that time, since the water treatment agent is dropped into the second portion 20e, the water treatment agent is effectively mixed into the water to be treated which overflows and falls. In addition, when the water treatment agent dropping promotion mechanism 24 is installed in the water treatment agent feeding machine 22, it avoids the situation that the water treatment agent becomes difficult to fall due to moisture, and the water treatment agent falls smoothly. Can be made.

このようにして、水処理剤が混合された被処理水を、被処理水排出口２０ｂを介して、攪拌槽１２に投入し、攪拌装置１４を作動させると、攪拌用羽根１４ｂの回転によって、被処理水が下方に差し向けられ、底壁に当たって被処理水が上昇し、円筒管１６の貫通孔１６ａから円筒管１６内に吸い込まれるので、攪拌槽１２内で下方から上方に向かって流れる水流が発生し、被処理水の攪拌が効率的に行われる。 In this way, when the water to be treated mixed with the water treatment agent is introduced into the agitation tank 12 through the treated water discharge port 20b and the stirring device 14 is operated, the rotation of the stirring blade 14b Since the water to be treated is directed downward and hits the bottom wall, the water to be treated rises and is sucked into the cylindrical tube 16 from the through hole 16a of the cylindrical tube 16, so that the water flow that flows upward from below in the stirring tank 12 Occurs and the water to be treated is efficiently stirred.

攪拌槽１２において十分に攪拌された被処理水は、連通路３２を介して、第１沈殿槽３０内に流入する。その際、連通路３２が攪拌槽１２の上部から第１沈殿槽３０内に斜め下方に延びているので、攪拌槽１２の上部に位置する比較的清浄な被処理水を第１沈殿槽３０内に流入させることができる。また、第１沈殿槽３０の隅部の流出口３２ｂから被処理水が流入するので、第１沈殿槽３０内で被処理水が旋回流となるので、沈殿作業を効果的に実施することができる。 The water to be treated sufficiently stirred in the stirring tank 12 flows into the first sedimentation tank 30 through the communication path 32. At that time, the communication path 32 extends obliquely downward from the upper part of the stirring tank 12 into the first precipitation tank 30, so that relatively clean water to be treated located at the upper part of the stirring tank 12 is passed into the first precipitation tank 30. Can be allowed to flow into. Moreover, since the to-be-processed water flows in from the outlet 32b of the corner of the 1st sedimentation tank 30, the to-be-processed water turns into a swirl flow in the 1st sedimentation tank 30, Therefore A sedimentation operation | work can be implemented effectively. it can.

次いで、被処理水は、連通路４２を介して、第２沈殿槽４０内に流入する。第２沈殿槽４０の連通路４２も、連通路３２と同様に、第２沈殿槽４０内に斜め下方に延びているので、第１沈殿槽３０の上部に位置する清浄な被処理水を第２沈殿槽４０内に流入させることができる。また、第２沈殿槽４０の隅部の流出口４２ｂから被処理水が流入するので、第２沈殿槽４０内で被処理水が旋回流となるので、沈殿作業を効果的に実施することができる。 Next, the water to be treated flows into the second sedimentation tank 40 through the communication path 42. Similarly to the communication path 32, the communication path 42 of the second settling tank 40 extends obliquely downward into the second settling tank 40, so that the clean water to be treated located at the top of the first settling tank 30 is supplied to the second settling tank 40. 2 It can flow into the settling tank 40. Further, since the water to be treated flows from the outlet 42b at the corner of the second sedimentation tank 40, the water to be treated becomes a swirling flow in the second sedimentation tank 40, so that the precipitation operation can be effectively performed. it can.

このようにして沈殿処理された被処理水は、排出口５０から装置外に排出される。 The water to be treated thus precipitated is discharged from the discharge port 50 to the outside of the apparatus.
