Description
本発明は、山間地における谷川などで取水された表流水の粗ろ過に好適な接合井に関する。 The present invention relates to a joint well suitable for rough filtration of surface water taken from valley rivers in mountainous areas.
通常の水道設備において、取水堰で取水した原水は、接合井や着水井を経て沈殿池やろ過地で浄化され、必要な滅菌処理を施した後、各戸に給水される。ここで、一般的な接合井は、取水堰からの導水管路における水圧の調整機能、原水に含まれる細砂の沈殿による除去機能などを備える。しかし、小規模水道施設においては、谷川などから表流水を取水してろ過池で浄化し、必要な滅菌処理を施した後、各戸に給水される。つまり、設置コストも掛かることから接合井が設置されない場合が多い。 In normal water supply facilities, raw water is taken in at an intake weir, passes through a junction well or landing well, is purified in a settling basin or filtration area, and is supplied to each house after undergoing the necessary sterilization treatment. Here, a typical joint well has functions such as adjusting the water pressure in the water conduit from the intake weir and removing fine sand contained in the raw water by precipitation. However, in small-scale water supply facilities, surface water is taken from valley rivers and other sources, purified in filtration ponds, and subjected to necessary sterilization before being supplied to individual households. In other words, joint wells are often not installed because of the installation cost.
また、従来から種々のろ過装置が開示されている（例えば、特許文献１及び特許文献２参照。）。特許文献１に開示された急速濾過装置は、下部に原水の流入口と、上縁に処理水の溢流口とを有する濾槽内に、粒状の浮上濾材と、その上方への流出を阻止する有孔阻止体とを設け、更に浮上濾材に洗浄水を与える洗浄水の供給管を設けて成ることを特徴としている。 Furthermore, various filtration devices have been disclosed in the past (see, for example, Patent Document 1 and Patent Document 2). The rapid filtration device disclosed in Patent Document 1 has a granular floating filter material in a filter tank that has an inlet for raw water at the bottom and an overflow port for treated water at the upper edge, and prevents it from flowing upward. The present invention is characterized in that it is provided with a perforated blocking body to provide cleaning water to the floating filter medium, and a cleaning water supply pipe that supplies cleaning water to the floating filter medium.
また、特許文献２に開示された濾過装置は、上端部に流出口、下端部に流入口を備えた濾過槽内に上下の目皿板、およびこの上下目皿板間に濾過材を配してなり、上下目皿板はそれぞれその上面側および下面側に流出口あるいは流入口に連通する空間部を有し、濾過材は複数個の微細多孔質繊維筒状体のカートリッジに収納され上下目皿板により押圧され密実に充填されていることを特徴としている。 Further, the filtration device disclosed in Patent Document 2 includes upper and lower perforated plates in a filtration tank having an outlet at the upper end and an inlet at the lower end, and a filter material arranged between the upper and lower perforated plates. The upper and lower mesh plate plates each have a space communicating with an outlet or an inlet on their upper and lower surfaces, and the filter material is housed in a cartridge made of a plurality of fine porous fiber cylinders. It is characterized by being pressed and densely packed by a plate plate.
特許文献１に開示された急速濾過装置によると、粒状の浮上濾材によって原水の濾過が可能な上向流式の濾過装置が提供されるものと思料する。また、特許文献２に開示された濾過装置によっても、上下目皿板間に配設された濾過材によって原水の濾過が可能な上向流式の濾過装置が提供されるものと思料する。 According to the rapid filtration device disclosed in Patent Document 1, it is thought that an upward flow type filtration device capable of filtering raw water using a granular floating filter material is provided. Further, it is believed that the filtration device disclosed in Patent Document 2 also provides an upward flow type filtration device in which raw water can be filtered using a filtration material disposed between the upper and lower perforated plates.
しかし、何れの濾過装置も原水の濾過は可能であるが、装置内に流入した細砂や枯れ葉などを積極的に集め、沈殿させて排出することが困難であるものと思料する。また、これらの濾過装置の上流側に従来の接合井を設置しても、従来の接合井では細砂の沈殿は多少可能であるが枯れ葉などを集めて沈殿させることは難しく、更には細砂や枯れ葉などの排出作業に非常に手間が掛かるため、維持管理作業が簡単なものが求められていた。 However, although any filtration device is capable of filtering raw water, it is considered difficult to actively collect fine sand, dead leaves, etc. that have flowed into the device, precipitate them, and then discharge them. In addition, even if a conventional joint well is installed upstream of these filtration devices, although it is possible to settle fine sand to some extent with the conventional joint well, it is difficult to collect and settle dead leaves, etc. Since it takes a lot of effort to remove dead leaves, etc., there was a need for something that was easy to maintain and manage.
また更に、小規模水道施設では、設置コストや設置スペース確保の問題から接合井そのものが設置されない場合もあり、接合井が設置されていないため、ろ過池に細砂や枯れ葉などが流入し、ろ過池に負荷が掛かっていた。 Furthermore, in small-scale water supply facilities, joint wells themselves may not be installed due to installation costs and installation space issues, and because joint wells are not installed, fine sand and dead leaves may flow into the filtration basin, causing filtration. The pond was under stress.
そこで本願発明者は、上記の問題点に鑑み、谷川などで取水される表流水の粗ろ過に好適であって、設置作業や維持管理作業が容易であるとともに、設置場所を選ばない接合井を提供するべく鋭意検討を重ねた結果、本発明に至ったのである。 In view of the above-mentioned problems, the inventor of the present application has developed a joint well that is suitable for rough filtration of surface water taken from rivers such as Tanigawa, is easy to install and maintain, and can be installed anywhere. As a result of extensive studies to provide this solution, the present invention was developed.
即ち、本発明は、取水した表流水を粗濾過するための接合井であって、箱状の接合井本体と、前記接合井本体の一の側壁の下方における側端部に配設される流入口と、前記一の側壁又は他の側壁の上方に配設される流出口と、前記流入口と前記流出口との間に配設される濾材入りカートリッジと、前記接合井本体の底板の中央部に配設される排泥口と、を含んで成り、前記流入口から前記接合井本体の下部に形成される流入室内に流入した前記表流水に渦流を生じさせるとともに、上向流によって前記表流水を粗濾過することを特徴とする。 That is, the present invention provides a joint well for rough filtration of taken surface water, which includes a box-shaped joint well body and a flow channel disposed at a lower side end of one side wall of the joint well body. an inlet, an outlet disposed above the one side wall or the other side wall, a cartridge containing a filter medium disposed between the inlet and the outlet, and a center of the bottom plate of the joint well body. a sludge drainage port disposed in the joint well body, the surface water flowing from the inflow port into the inflow chamber formed at the lower part of the joint well body generates a vortex flow, and the upward flow causes the It is characterized by rough filtration of surface water.
また、本発明の接合井において、前記流入室内の隅部に、整流板が配設されていることを特徴とする。 Furthermore, the junction well of the present invention is characterized in that a rectifying plate is disposed at a corner of the inflow chamber.
更に、本発明の接合井において、前記接合井本体が組立式であることを特徴とする。 Furthermore, in the joint well of the present invention, the joint well main body is of an assembly type.
本発明の接合井によると、谷川などで取水される表流水（原水）に含まれる細砂や枯れ葉などをある程度、除去することができるため、本発明の接合井の下流側に設置される沈殿地やろ過池の負荷を軽減することができる。 According to the joint well of the present invention, fine sand and dead leaves contained in surface water (raw water) taken from valley rivers etc. can be removed to some extent, so the sedimentation well installed downstream of the joint well of the present invention It can reduce the load on the soil and filtration pond.
また、本発明の接合井によると、接合井内に流入する表流水に渦流が生じ、流入室の中央部付近に細砂等を集めて沈殿させることができるため、細砂等の排出が容易にでき、維持管理作業の負担が大幅に軽減される。 Further, according to the joint well of the present invention, a vortex is generated in the surface water flowing into the joint well, and fine sand, etc. can be collected and precipitated near the center of the inflow chamber, so that fine sand, etc. can be easily discharged. This greatly reduces the burden of maintenance work.
更に、本発明の接合井において、流入室内の隅部に整流板を配設することによって、よりスムーズに渦流を生じさせることができ、細砂などの集積効率の更なる向上が図られる。 Furthermore, in the joint well of the present invention, by arranging a rectifying plate at the corner of the inlet chamber, a vortex can be generated more smoothly, and the efficiency of accumulating fine sand and the like can be further improved.
また更に、本発明の接合井において、組立式とすることによって人力での運搬が可能となり、運搬及び設置作業の更なる省力化が図られるとともに、設置場所も選ばないため、従来は設置が困難であった小規模水道施設においても設置することが可能となる。 Furthermore, since the joint well of the present invention is an assembly type, it can be transported by hand, further saving labor in transport and installation work, and it can be installed anywhere, making installation difficult in the past. It becomes possible to install it even in small-scale water supply facilities.
以下、本発明の一実施形態について、図面に基づいて説明する。図１は、本発明の一実施形態に係る接合井１０を示す平面図、図２は図１に示した接合井１０に係るＡ－Ａ線断面図、図３は図１に示した接合井１０に係るＢ－Ｂ線断面図、図４は図２に示した接合井１０に係るＣ－Ｃ線断面図（但し、濾材入りカートリッジ２０を除く。）である。これら図１から図４に示すように、本実施形態に係る接合井１０は、谷川などで取水した表流水を粗濾過するための接合井であって、少なくとも箱状の接合井本体１２と、接合井本体１２の一の側壁１４ａの下方における側端部に配設される流入口１５と、他の側壁１４ｂの上方に配設される流出口１７と、流入口１５と流出口１７との間に配設される濾材入りカートリッジ２０と、接合井本体１２の底板１９の中央部に配設される排泥口２２とを含んで構成されている。なお、本実施形態の接合井１０は、図２及び図３に示すように、接合井本体１２の上部に蓋部材２４を備えているが、図１においては接合井本体１２内を表すために蓋部材２４を省略している。 Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a plan view showing a junction well 10 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of the junction well 10 shown in FIG. 1, and FIG. 10, and FIG. 4 is a cross-sectional view taken along the line CC of the joint well 10 shown in FIG. 2 (excluding the cartridge 20 containing the filter medium). As shown in FIGS. 1 to 4, the joint well 10 according to the present embodiment is a joint well for roughly filtering surface water taken from a valley, etc., and includes at least a box-shaped joint well body 12, An inlet 15 disposed at the lower side end of one side wall 14a of the joint well body 12, an outlet 17 disposed above the other side wall 14b, and an inlet 15 and an outlet 17. It is configured to include a filter medium-containing cartridge 20 disposed therebetween, and a mud draining port 22 disposed at the center of the bottom plate 19 of the joint well body 12. Note that, as shown in FIGS. 2 and 3, the joint well 10 of this embodiment includes a lid member 24 on the top of the joint well body 12, but in FIG. The lid member 24 is omitted.
本実施形態の接合井１０に係る流入口１５は、図１及び図２に示すように、接合井本体１２の一の側壁１４ａの下方における側端部に配設されている。流入口１５を側壁１４ａの下端部ではなく、下端部から少し上方の位置に設けることによって、流入室２６の底部に沈殿した表流水に含まれる細砂などをかき混ぜることがなく、スムーズに流入室２６の中央部に集めながら沈殿させることができる。 As shown in FIGS. 1 and 2, the inlet 15 of the joining well 10 of this embodiment is disposed at the lower side end portion of one side wall 14a of the joining well body 12. By providing the inlet 15 not at the lower end of the side wall 14a but at a position slightly above the lower end, fine sand contained in the surface water that has settled at the bottom of the inflow chamber 26 is not stirred, and the inflow chamber 26 can be smoothly filled. It can be precipitated while collecting in the center of 26.
流入口１５には流入管１６が接続されており、表流水が流入管１６を経て流入口１５から流入室２６に導水される。ここでそして、本実施形態では流入口１５が一の側壁１４ａの側端部に配設されているため、流入口１５から流入室２６に流入した表流水は他の側壁１４ｃに沿って流れ、他の側壁１４ｂに当たって流れの方向が変化する（図４中、矢印Ｘ１）。他の側壁１４ｂによって流れる方向が変化した表流水は、次に他の側壁１４ｄに当たって流れの方向が変化し（同図中、矢印Ｘ２）、他の側壁１４ｄに当たって流れる方向が変化した表流水は、更に一の側壁１４ａに当たって流れの方向が変化する（同図中、矢印Ｘ３）。そして、一の側壁１４ａに当たって流れる方向が変化した表流水は、他の側壁１４ｃに当たるとともに、流入口１５から流入する表流水によって流れの方向が変化し、他の側壁１４ｃに沿って流れることとなる。 An inflow pipe 16 is connected to the inflow port 15 , and surface water is guided from the inflow port 15 to the inflow chamber 26 via the inflow pipe 16 . In this embodiment, since the inlet 15 is disposed at the side end of one side wall 14a, the surface water flowing into the inlet chamber 26 from the inlet 15 flows along the other side wall 14c. The direction of the flow changes when it hits the other side wall 14b (arrow X1 in FIG. 4). The surface water whose flow direction has been changed by the other side wall 14b then changes its flow direction by hitting the other side wall 14d (arrow X2 in the figure), and the surface water whose flow direction has changed by hitting the other side wall 14d changes its flow direction. Furthermore, the direction of the flow changes when it hits the first side wall 14a (arrow X3 in the figure). Then, the surface water whose flow direction has changed by hitting one side wall 14a hits the other side wall 14c, and the flow direction is changed by the surface water flowing in from the inlet 15, and flows along the other side wall 14c. .
つまり、流入口１５から流入室２６に流入した表流水には、流入室２６において渦流が生じることとなる。このように、流入室２６において表流水に渦流を生じさせることによって、表流水に含まれる細砂などを底板１９の中央部付近に集めながら沈殿させることができる。従って、底板１９の中央部付近に集められつつ沈殿した細砂などは、排泥口２２から排泥管２３を経て容易に接合井本体１２外へ排出することができる。 In other words, a vortex is generated in the surface water flowing into the inflow chamber 26 from the inflow port 15 in the inflow chamber 26 . In this manner, by creating a vortex in the surface water in the inflow chamber 26, fine sand and the like contained in the surface water can be collected and precipitated near the center of the bottom plate 19. Therefore, the fine sand and the like that have settled near the center of the bottom plate 19 can be easily discharged from the mud draining port 22 to the outside of the joint well body 12 via the mud draining pipe 23.
そして、流入口１５から流入した表流水に流入室２６で渦流を生じさせ、細砂などを中央部に集めて沈殿させつつ、上向流によって、流入室２６の上方に配設された濾材で枯れ葉などの浮遊物の流出を防ぎつつ粗濾過する。本実施形態に係る濾材は、濾材が充填されたカートリッジ式であり、この濾材入りカートリッジ２０を流入室２６の上方に配設している。なお、濾材としては特に限定されないが、自重の軽い木炭や竹炭などが好適である。 Then, a vortex is generated in the surface water flowing in from the inflow port 15 in the inflow chamber 26, and while fine sand and the like are collected and precipitated in the center, the filter medium disposed above the inflow chamber 26 is caused to flow upward. Performs coarse filtration while preventing floating matter such as dead leaves from flowing out. The filter medium according to this embodiment is of a cartridge type filled with the filter medium, and the cartridge 20 containing the filter medium is disposed above the inflow chamber 26. Note that the filter medium is not particularly limited, but charcoal, bamboo charcoal, etc., which are light in weight, are suitable.
また、濾材入りカートリッジ２０の形状や大きさ、設置数、設置態様なども特に限定されない。本実施形態では、濾材として木炭などを充填した３つの濾材入りカートリッジ２０を、流入室２６上方の側壁１４ａ～１４ｄの内周面に設けた設置枠２７上に載置している。このように構成することによって、接合井本体１２への濾材入りカートリッジ２０の設置作業や交換作業を容易に行うことができる。 Moreover, the shape, size, number of installations, installation mode, etc. of the filter medium-containing cartridge 20 are not particularly limited. In this embodiment, three filter cartridges 20 filled with charcoal or the like as filter media are placed on an installation frame 27 provided on the inner peripheral surface of the side walls 14a to 14d above the inflow chamber 26. With this configuration, it is possible to easily install and replace the filter medium-containing cartridge 20 in the joint well body 12.
流入室２６で渦流が生じた表流水は、上向流によって濾材入りカートリッジ２０を通過し、濾材入りカートリッジ２０の上方に配設された流出口１７から流出管１８を経て下流側へ導水される。本実施形態に係る流出口１７は他の側壁１４ｂに配設されているが、流出口１７が配設される側壁は特に限定されず、流入口１５が配設された一の側壁１４ａであってもよく、他の側壁１４ｃ、１４ｄであってもよい。 The surface water that has generated a whirlpool in the inflow chamber 26 passes through the filter medium-containing cartridge 20 due to an upward flow, and is led to the downstream side through an outflow pipe 18 from an outlet 17 disposed above the filter medium-containing cartridge 20. . Although the outflow port 17 according to the present embodiment is disposed on the other side wall 14b, the side wall on which the outflow port 17 is disposed is not particularly limited. Alternatively, other side walls 14c and 14d may be used.
また、本実施形態では、流出口１７が配設された位置よりも上方に溢流口２８が配設され、溢流管２９が接続されている。流入口１５からの表流水の流入量が流出口１７からの流出量より多い場合には、溢流口２８から表流水を排水することによって容易に流量調整を行うことができる。なお、本実施形態に係る溢流口２８は側壁１４ｄに配設されているが、溢流口２８が配設される側壁は特に限定されず、一の側壁１４ａであってもよく、他の側壁１４ｂ、１４ｃであってもよい。 Furthermore, in this embodiment, an overflow port 28 is provided above the position where the outflow port 17 is provided, and an overflow pipe 29 is connected thereto. If the amount of surface water flowing in from the inlet 15 is greater than the amount flowing out from the outlet 17, the flow rate can be easily adjusted by draining the surface water from the overflow port 28. Note that although the overflow port 28 according to the present embodiment is disposed on the side wall 14d, the side wall on which the overflow port 28 is disposed is not particularly limited. It may be the side walls 14b, 14c.
更に、本実施形態では、側壁１４ｄの下端部側方に排泥口２２ａが配設され、この排泥口２２ａに排泥管２３ａが接続されている。本実施形態に係る流入室２６に流入した表流水に含まれる細砂などは、渦流によって流入室２６の中央部付近に集められ、沈殿した細砂などは底板１９に配設された排泥口２２から排出されるが、別途、排泥口２２ａを配設し、排泥口２２ａを空けた状態で表流水を流入室２６に導水することによって、流入室２６の底部に残った細砂などを表流水の渦流で排出することができる。 Further, in this embodiment, a mud draining port 22a is provided on the side of the lower end of the side wall 14d, and a mud draining pipe 23a is connected to this mud draining port 22a. Fine sand and the like contained in the surface water that has flowed into the inflow chamber 26 according to the present embodiment are collected near the center of the inflow chamber 26 by the vortex, and the fine sand and the like that have settled are removed from the mud draining port provided in the bottom plate 19. However, fine sand, etc. remaining at the bottom of the inlet chamber 26 can be removed by separately providing a mud draining port 22a and guiding surface water to the inflow chamber 26 with the mud draining port 22a open. can be discharged by vortexing of surface water.
以上、本発明の一実施形態に係る接合井１０について詳述したが、本実施形態において、流入室２６内の隅部には、整流板３０が配設されていることが特に好ましい。流入室２６に流入する表流水には、流入口１５の配設位置の関係で流入室２６内において渦流が生じるが、流入室２６内の隅部に整流板３０を配設することによって、よりスムーズに渦流を生じさせることができ、細砂などの集積効率の更なる向上が図られる。 The junction well 10 according to an embodiment of the present invention has been described in detail above, but in this embodiment, it is particularly preferable that a rectifying plate 30 is disposed at a corner of the inflow chamber 26. In the surface water flowing into the inflow chamber 26, a vortex is generated in the inflow chamber 26 due to the arrangement position of the inflow port 15, but by arranging the rectifying plate 30 at the corner of the inflow chamber 26, it is possible to A vortex can be smoothly generated, and the efficiency of accumulating fine sand and the like can be further improved.
以上、本発明の接合井の実施形態について詳述したが、本発明の技術的思想を実質的に限定するものと解してはならない。例えば、本発明の一実施形態の接合井１０に係る流入室２６内において、流入口１５に導水管２１が配設されていることが好ましい。導水管２１を配設することによって、流入口１５から流入室２６に流入する表流水を導水管２１で更に整流することができ、よりスムーズに流入室２６内において表流水に渦流を生じさせることができる。 Although the embodiments of the junction well of the present invention have been described in detail above, this should not be construed as substantially limiting the technical idea of the present invention. For example, it is preferable that the water conduit 21 is disposed at the inlet 15 in the inflow chamber 26 of the joint well 10 according to the embodiment of the present invention. By arranging the water conduit 21, the surface water flowing into the inflow chamber 26 from the inlet 15 can be further rectified by the water conduit 21, and a vortex can be generated in the surface water in the inflow chamber 26 more smoothly. I can do it.
また、本発明の接合井に係る接合井本体は一体のものであってもよいが、高さ方向に分割された組立式としてもよい。図２などに示すように、本発明の実施形態に係る接合井１０において、接合井本体１２を上下方向に分割し、上側の側壁と下側の側壁とをそれぞれボルト３１とナット３２で締結することによって、接合井１０を容易に組み立てることができる。このように接合井本体１２を組立式とすることによって、接合井１０の設置箇所までの運搬作業の労力を軽減することができる。本発明はその要旨を逸脱しない範囲で、当業者の創意と工夫により、適宜に改良、変更又は追加をしながら実施できる。 Further, the joint well body according to the joint well of the present invention may be integrated, but it may also be an assembly type divided in the height direction. As shown in FIG. 2 and the like, in the joint well 10 according to the embodiment of the present invention, the joint well main body 12 is divided in the vertical direction, and the upper side wall and the lower side wall are fastened with bolts 31 and nuts 32, respectively. By this, the joining well 10 can be easily assembled. By making the joint well main body 12 an assembly type in this way, the labor involved in transporting the joint well 10 to the installation location can be reduced. The present invention can be implemented with appropriate improvements, changes, or additions based on the ingenuity and ingenuity of those skilled in the art without departing from the gist thereof.
