従来、この種の活性汚泥法における最終沈殿池として要求される基本的な機能 は、固液分離と汚泥返送である。そして、使用される沈殿槽の基本的な構造とし ては、図５に示すようなものがあった。図５は従来のホッパー型沈殿分離装置の 縦断面図で、自然沈殿型の装置を示してある。図４は同装置の平面図である。 Conventionally, the basic functions required as the final settling tank in this type of activated sludge method are solid-liquid separation and sludge return. The basic structure of the settling tank used was as shown in FIG. FIG. 5 is a vertical cross-sectional view of a conventional hopper type sedimentation separation device, showing a natural sedimentation type device. FIG. 4 is a plan view of the device.
【０００３】 図において、Ａは上層に容積部Ｂと下層に沈殿部Ｃとを有するホッパー型の沈 殿槽で、この沈殿槽Ａの上部中心には処理水を流入して分離させるための分離筒 Ｄが配設されている。また、この分離筒Ｄには処理水を流入させるための流入管 Ｅが図４に示すように分離筒Ｄの軸中心に対して延直に接続されている。そして 、前記沈殿槽Ａの上端開口部には越流堰Ｆが形成されており、この越流堰Ｆから 上澄水が外部に排出するように排出管Ｇが接続されている。 Ｈは分離筒Ｄの上端部に形成した空気抜部であり、Ｉは分離した汚泥などの沈 殿物を排出するための汚泥排出管で、沈殿部Ｃの下端部に形成されている。Ｊは 汚泥排出管Ｉのバルブである。In the figure, A is a hopper type sedimentation tank having a volume B in the upper layer and a sedimentation C in the lower layer, and a separation for inflowing and separating the treated water into the upper center of the sedimentation tank A. A cylinder D is arranged. Further, as shown in FIG. 4, an inflow pipe E for inflowing the treated water is connected to the separation cylinder D in a straight line with respect to the axial center of the separation cylinder D. An overflow weir F is formed at the upper end opening of the settling tank A, and a discharge pipe G is connected so that the supernatant water is discharged from the overflow weir F to the outside. H is an air vent formed at the upper end of the separation cylinder D, and I is a sludge discharge pipe for discharging separated sludge and other sediments, and is formed at the lower end of the settling part C. J is a valve of the sludge discharge pipe I.
【０００４】 そして、沈殿槽Ａの容積部Ｂの有効容量は、１日当たり平均汚水量の６分の１ 以上、すなわち凡そ４時間以上の沈殿時間が必要とされ、また、沈殿部Ｃの斜辺 底面となるホッパーの勾配は、装置全体の強度との関係から６０度以上となるよ うに形成されている。The effective capacity of the volume B of the settling tank A requires a one-sixth or more of the average amount of sewage per day, that is, a settling time of about 4 hours or more, and the slanted bottom surface of the settling section C. The slope of the hopper is formed to be 60 degrees or more in consideration of the strength of the entire device.
【０００５】[0005]
従来のホッパー型沈殿分離装置は、上記のように構成されており、沈殿槽Ａの 沈殿部Ｃのホッパーの勾配を６０度に形成する必要から、ある程度の容積部Ｂを 確保しながら全体を構成すると沈殿部Ｃの長さｔ１が長くなる結果、全体として 縦長の装置となり、装置全体が大型化するものであった。そして、大型であるに もかかわらず、その割合には処理水の処理能力が低いという問題を有していた。The conventional hopper type sedimentation separation device is configured as described above, and since the inclination of the hopper of the sedimentation portion C of the sedimentation tank A needs to be formed at 60 degrees, the entire construction is achieved while securing a certain volume portion B. As a result, the length t 1 of the settling portion C becomes long, resulting in a vertically long device as a whole, and the entire device becomes large. And despite the large size, there was a problem that the treatment capacity of the treated water was low.
【０００６】 また、沈殿槽Ｃに沈殿された物質は、その物質の化学変化等によって突然に浮 上する場合（バルキング現象）があり、その浮上物質が上澄水と共に、越流堰Ｆ を越えて外部に越流するという問題を有している。この大きな原因は、沈殿槽Ａ の上部に配設した分離筒Ｄが真直な円筒形状に形成されているために、分離筒Ｄ の下端の開口部分の外側に浮上物質が浮上するので、大部分が上澄水と共に越流 するものである。The substance settled in the settling tank C may suddenly float up due to a chemical change of the substance (bulking phenomenon), and the floating substance, together with the supernatant water, crosses the overflow weir F 1. It has the problem of overflowing to the outside. This is largely due to the fact that the separation cylinder D arranged in the upper part of the settling tank A is formed in a straight cylindrical shape, so that the levitation substance floats outside the opening at the lower end of the separation cylinder D 1, so most of the reason. Will overflow with the clear water.
【０００７】 しかも、分離筒Ｄの軸中心に接続されている流入管Ｅから分離筒Ｄへの処理水 は、そのまま容積部Ｂに流入するために、その流入速度によって容積部Ｂ内で処 理水が撹拌されてしまい、沈殿処理のために時間を要するという問題を有してい た。特にホッパー型沈殿分離装置は、自然沈殿型の装置であるために、通常でも ４時間以上の沈殿処理時間を要するというものであったが、処理水の流入による 撹拌により更に沈殿処理時間を要するという課題を有している。Moreover, the treated water from the inflow pipe E, which is connected to the axial center of the separation cylinder D, to the separation cylinder D flows into the volume B as it is, and therefore is processed in the volume B by its inflow speed. There was a problem that the water was agitated and it took time for the precipitation treatment. In particular, the hopper-type sedimentation separator required a sedimentation treatment time of 4 hours or longer even though it is a natural sedimentation-type equipment, but it is said that the agitation due to the inflow of treated water requires an additional sedimentation treatment time. Have challenges.

本考案は上記のような課題を解決するために次のような手段を講じたものであ る。 登録を受けようとする第１の考案は、上層に容積部と下層に沈殿部とを有する ホッパー型の沈殿槽と、この沈殿槽の上部中心に分離筒を配設すると共に、この 分離筒に処理水の流入管を接続して形成し、前記沈殿槽の上端開口部に越流堰を 形成すると共に、この越流堰からの上澄水を外部に排出する排出管を接続をして なるホッパー型沈殿分離装置において、上記の分離筒を竪筒部とフレア筒部とか ら形成し、この竪筒部とフレア筒部との接続部分で、かつ、分離筒の接線部に流 入管を接続して形成するようにしたものである。 すなわち、分離筒を竪筒部とフレア筒部とから構成し、しかも流入管を両者の 接続部に接続形成してあるので、流入管からの処理水は、フレア筒部内を渦巻き 状態で移流し、容積部に対して一定の水の流れが形成され、浮遊性物質の沈降が 促進される。 The present invention takes the following means in order to solve the above problems. The first invention to receive registration is to dispose a hopper type sedimentation tank having a volume part in the upper layer and a sedimentation part in the lower layer, a separation cylinder at the center of the upper part of the sedimentation tank, and to the separation cylinder. A hopper formed by connecting an inflow pipe of treated water, forming an overflow weir at the upper end opening of the settling tank, and connecting a discharge pipe for discharging the supernatant water from the overflow weir to the outside. In the type settling separation device, the above-mentioned separation cylinder is formed from the vertical cylinder portion and the flare cylinder portion, and the inflow pipe is connected to the connection portion between the vertical cylinder portion and the flare cylinder portion and to the tangent portion of the separation cylinder. It is designed to be formed. That is, since the separation tube is composed of the vertical tube portion and the flare tube portion, and the inflow pipe is connected to the connecting portion between the both, the treated water from the inflow pipe is advected in the flare tube portion in a spiral state. , A constant flow of water is formed with respect to the volume, facilitating the sedimentation of buoyant substances.
【０００９】 登録を受けようとする第２の考案は、上記第１の発明の装置をより具体的な構 成としたもので、分離筒を構成するフレア筒部の開き角度を６０度に形成すると 共に、流入管の接続角度を５度〜１５度の範囲で接続し、沈殿槽の沈殿部の傾斜 角度を４５度に形成したものである。 この結果、従来のホッパー型沈殿分離装置に比べて容積部が同じ容量でありな がら、沈殿部の長さを短縮することができるので、装置全体の小型化を図ること ができる。また、流入管の接続角度は、フレア筒部の開き角度と相まって浮遊性 物質の沈降促進効果がより一層良好なものとなる。A second invention for receiving registration is a more specific configuration of the device of the first invention, in which an opening angle of the flare tube portion constituting the separation tube is formed to be 60 degrees. At the same time, the connection angle of the inflow pipe is connected in the range of 5 to 15 degrees, and the inclination angle of the settling section of the settling tank is set to 45 degrees. As a result, it is possible to reduce the length of the sedimentation unit while the volume of the sedimentation unit is the same as that of the conventional hopper-type sedimentation separation device, so that the overall size of the device can be reduced. Further, the connection angle of the inflow pipe, together with the opening angle of the flare tube portion, further enhances the effect of promoting the sedimentation of the floating substances.
【００１０】[0010]
流入管からの処理水は、竪筒部とフレア筒部との接続部で、かつこれらの分離 筒の接線部に接続されているために、処理水がフレア筒部６内において渦巻き状 態で下方向に移流されて容積部に流れるので、上澄水と活性汚泥や沈降性浮遊物 との分離が促進されると共に、容積部内において処理水の流入による撹拌作用が 少ないものとなる。そして、沈降した活性汚泥や沈降性浮遊物等の沈殿物は、バ ルキング現象により浮上するが、これらの沈降性浮遊物などは再びフレア筒部内 において渦巻き状態で下方向に移流されて、分離効率が良好となる。 The treated water from the inflow pipe is connected to the vertical and flare cylinders and is connected to the tangent of these separating cylinders, so that the treated water is in a spiral state in the flare cylinder 6. Since it is advected downwards and flows into the volume, the separation of supernatant water from activated sludge and sedimentable suspended matter is promoted, and the stirring action by the inflow of treated water in the volume is reduced. Then, the settled sediment such as activated sludge and settling suspended matter floats up due to the bulking phenomenon, but these settling suspended matter etc. are again swirled downward in the flare tube part in a swirling state, and the separation efficiency is increased. Will be good.

以下において、本考案の実施例を図面に基づいて詳細に説明する。 図１はホッパー型沈殿分離装置の縦断面図で、図２は分離筒の縦断面図で、図 ３は同装置の平面図である。 Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a hopper type precipitation separation device, FIG. 2 is a vertical cross-sectional view of a separation cylinder, and FIG. 3 is a plan view of the same device.
【００１２】 図において、１は処理水を沈殿させるための沈殿槽で、この沈殿槽１は上層に 容積部２と下層に沈殿部３とを有するホッパー型に形成されている。なお、図示 の実施例において、この沈殿槽１は平面視が図２に示すように円筒形状に形成さ れているが、角筒形状であっても良い。 この沈殿槽１の上部中心に分離筒４を配設すると共に、この分離筒４に処理水 の流入管を接続して形成されている。そして、前記沈殿槽１の上端開口部１ａに 越流堰８を形成すると共に、この越流堰８からの上澄水を外部に排出する排出管 ９が越流堰８の外側部８ａに接続されて形成されている。また、分離筒４の上端 部には空気抜部４ａが形成されている。In the figure, 1 is a sedimentation tank for precipitating treated water, and this sedimentation tank 1 is formed in a hopper type having a volume part 2 in an upper layer and a sedimentation part 3 in a lower layer. In the illustrated embodiment, the settling tank 1 is formed in a cylindrical shape in plan view as shown in FIG. 2, but may be in a rectangular tube shape. A separation cylinder 4 is arranged at the center of the upper part of the settling tank 1, and a treatment water inflow pipe is connected to the separation cylinder 4. Then, the overflow weir 8 is formed at the upper end opening 1a of the settling tank 1, and a discharge pipe 9 for discharging the supernatant water from the overflow weir 8 to the outside is connected to the outer portion 8a of the overflow weir 8. Is formed. An air vent 4a is formed at the upper end of the separating cylinder 4.
【００１３】 上記の分離筒４は竪筒部５とフレア筒部６とから形成し、この竪筒部５とフレ ア筒部６との接続部分に流入管７を５度から１５度の角度範囲で接続することが 望ましく、図示の実施例においては５度の角度をもって接続してある。また、流 入管７は分離筒４の軸中心ではなく、分離筒４の接線部に接続されている。 なお、この流入管７の分離筒４に対する接続角度は、水平に近い５度以下であ ると、処理水がフレア筒部６内において渦巻き状態で下方向に移流されることが なく、水中の浮遊物が撹拌されて分離されにくくなる。また、１５度以上である と、処理水の流れが直接的に下方向に働くので沈殿部３に積層している汚泥を吹 き上げることとなり、同様に分離が不完全となる。 上記流入管７の途中には、図示しないが分離筒４へ所定量の処理水を送るため の定量ポンプが設けられている。The separation cylinder 4 is formed of a vertical cylinder portion 5 and a flare cylinder portion 6, and an inflow pipe 7 is connected to the connection portion between the vertical cylinder portion 5 and the flare cylinder portion 6 at an angle of 5 degrees to 15 degrees. It is desirable to connect within a range, and in the illustrated embodiment, they are connected at an angle of 5 degrees. Further, the inflow pipe 7 is connected not to the axial center of the separation cylinder 4 but to the tangent portion of the separation cylinder 4. When the connection angle of the inflow pipe 7 to the separation cylinder 4 is 5 degrees or less close to the horizontal, the treated water is not advected downward in the flare cylinder portion 6 in a swirl state, and The suspended matter is agitated and becomes difficult to separate. On the other hand, if it is 15 degrees or more, the flow of the treated water directly works downward, so that the sludge accumulated in the settling section 3 is blown up, and the separation is also incomplete. Although not shown, a metering pump for sending a predetermined amount of treated water to the separation cylinder 4 is provided in the middle of the inflow pipe 7.
【００１４】 また、分離筒４を構成するフレア筒部６は、下方向の開き角度を６０度に形成 すると共に、下層である沈殿部３の少なくとも３分の２以上の表面を覆うように 形成されている。従って、このフレア筒部６が例え６０度の開き角度に形成され ていたとしても、その範囲が沈殿部３の表面の３分の２以下しかカバーしていな い場合には、バルキング現象により浮上する沈降物が分離筒４の外側より上昇し て越流堰８から外部に上澄水と共に排出されてしまうことになる。 しかしながら、この浮上した沈降物はフレア筒部６によって流入してくる処理 水と共に再び渦巻き状態で下方向に移流されるために、上澄水と一緒に外部に排 出される割合が少なくなり、処理水の処理効率が高いものとなる。Further, the flare tube portion 6 that constitutes the separation tube 4 has a downward opening angle of 60 degrees and is formed so as to cover at least two-thirds or more of the surface of the lower settling portion 3. Has been done. Therefore, even if the flare tube portion 6 is formed with an opening angle of 60 degrees, if the range covers only two-thirds or less of the surface of the sedimentation portion 3, it rises due to the bulking phenomenon. The resulting sediment rises from the outside of the separation cylinder 4 and is discharged from the overflow weir 8 to the outside together with the supernatant water. However, since the floated sediment is advancing downward again in a spiral state together with the treated water flowing in by the flare tube portion 6, the ratio of being discharged to the outside together with the supernatant water is reduced, and the treated water is reduced. The processing efficiency of is high.
【００１５】 前記の沈殿槽１を構成する沈殿部３の傾斜角度は、そのホッパーの勾配を４５ 度に形成してある。その結果、従来のホッパーの勾配に比べると、沈殿部３の長 さｔ２を短くすることができ、装置全体の小型化を図ることができる。 １０は分離した汚泥などの沈殿物を排出するための汚泥排出管で、沈殿部３の 下端部に接続形成されている。１１は汚泥排出管のバルブである。The inclination angle of the settling section 3 constituting the settling tank 1 is such that the hopper is inclined at 45 degrees. As a result, the length t 2 of the settling section 3 can be shortened as compared with the conventional gradient of the hopper, and the overall size of the apparatus can be reduced. Reference numeral 10 denotes a sludge discharge pipe for discharging the separated sediment such as sludge, which is connected to the lower end of the sedimentation section 3. Reference numeral 11 is a valve of the sludge discharge pipe.

In the type settling separation device, the separation cylinder is formed from a vertical cylinder portion and a flare cylinder portion, and an inflow pipe is connected to the connection portion between the vertical cylinder portion and the flare cylinder portion and the tangent portion of the separation cylinder. It is designed to be formed. Therefore, compared with the conventional hopper type sedimentation separator, the treated water can be separated more reliably and the treatment time of the treated water can be shortened.

The connection is made within the range of 15 degrees, and the inclination angle of the settling section of the settling tank is set to 45 degrees. Therefore, the floating material that floats due to the bulking phenomenon can be advected downward again and only the supernatant water can be discharged. In addition, it has the effect of reducing the size of the entire device.
