【発明の属する技術分野】
本発明は排水装置用水面制御装置、特に、雨水と汚水を合流して排水処理するための排水装置において汚水と雨水とを分水する雨水吐き室(分水人孔)内の水面を制御する制御装置に関するものである。
【0002】
【従来の技術】
図5Aは従来の合流式下水道分水人孔の平面図、図6A及び図6Bは図5Aの合流式下水道の分水人孔の晴天時の状態を示し、1は分水堰、2は流入管、3は遮集管、4は放流管、5は流入する浮遊性の夾雑物である。図7A,図7B,図8A及び図8Bは雨天時の状態である。
【0003】
従来の分水人孔においては、晴天時は図6A,図6Bのように流入管2から夾雑物5を含んだ汚水が遮集管3へ全量流れ込み、下水処理場、ポンプ場へ流下する。また、雨天時は図7A,図7Bのように汚水と共に雨水も分水人孔内へ流入し、一定量以上の水量になると図8A,図8Bに示すように流入管2と放流管4間に介挿した分水堰1を越流し、夾雑物を含んだ汚水の一部も放流管4を通じて公共用水域へと流出する。
【0004】
【発明が解決しようとする課題】
上記のように、従来の分水人孔では、流入する浮遊性の夾雑物5が雨天時に遮集管3へ流入せず放流管4を介して公共用水域へ流出し、公共用水域の水質汚濁の原因のひとつとなっている。この要因の1つには、従来の分水人孔における雨天時の水理特性が挙げられる。従来の分水人孔では図6A,図6Bのように晴天時は流入管2から遮集管3に向かって水面勾配が形成されるため、浮遊性夾雑物5は流れに乗って遮集管3へ全量流れ込む。しかし、雨天時においては図7A,図7Bのように、遮集管3が水没し、遮集管3入口付近の水面が盛り上がるようになり、晴天時のように流入管2から遮集管3へ向かう水面勾配が形成されない。この状態においては浮遊性夾雑物5は遮集管3へ流入せず、分水人孔内に滞留する。さらに分水人孔への流入水量が増加し分水人孔内水深が分水堰1の高さを上回るようになると、図8A,図8Bのように分水堰1を越流することで、流入管2から放流管4へ向かう水面勾配が形成される。この時浮遊性夾雑物5は流れに乗って放流管4を通じて公共用水域へほぼ全量流出する。
【0005】
このような課題を解決するための手段としては、浮遊性の夾雑物5が遮集管3へ流入し易い流れを分水人孔内で発生させる必要があり、従来の分水人孔を改良し、浮遊性夾雑物の公共用水域への流出削減を行う必要がある。
【0006】
【課題を解決するための手段】
本発明の排水装置用水面制御装置は、下水道雨水吐き室における流入管と遮集管間に介挿した、その頂面の高さを、流入管と放流管間に介挿した分水堰の高さより低くした制御板と、上記流入管と上記分水堰間に介挿せしめた、上記分水堰の天端からやや下方の位置にその下端を有するガイドウォールとを有することを特徴とする。
【0008】
【発明の実施の形態】
以下図面によって本発明の実施例を説明する。
【0009】
本発明においては図1及び図2に示すように上記遮集管3と上記流入管2間に制御板6を介挿し、上記制御板6の頂面の高さを分水堰1の高さより低くなるようにし、また、上記制御板6の下端と遮集管3の底面間に隙間を形成し、晴天時この隙間から汚水が遮集管3内に流れ得るようにする。また、図3及び図4に示すように上記分水堰1の天端からやや下方の位置にその下端を配置せしめた垂直ガイドウォール7を上記流入管2と分水堰1間に介挿せしめる。
【0010】
本発明の排水装置用水面制御装置は上記のような構成であるから図1のように雨天時には制御板6を越流することで流入管2から遮集管3へ向かう水面勾配が形成され、浮遊性夾雑物5は流れに乗って遮集管3へほぼ全量流入する。さらに分水人孔への流入水量が増加し分水人孔内水深が分水堰1の高さを上回るようになると、図2のように制御板6の越流による流入管2から遮集管3へ向かう水面勾配が形成されるとともに、分水堰1を越流することによる流入管2から放流管4へ向かう水面勾配が形成される。しかし、後者の水面勾配の方が前者より大きいため、放流管4へ向かう表面流の勢力が上回り、浮遊性夾雑物5は大半が流れに乗って分水堰1を越えて放流管4へ流出し、一部のみが遮集管3へ流入することになるためその遮集効果はいまだ十分ではない。
【0012】
この実施例によれば、雨天時において分水人孔水深が分水堰1の高さを上回るような場合においては、図4に示すようにガイドウォール7付近で水面が盛り上がるようになり、流入管2から分水堰1へ向かう水面勾配が形成されないようになる。前述の実施例のように制御板6を越流することにより流入管2から遮集管3へ向かう水面勾配が形成されるため、浮遊性夾雑物5の大半が表面流に乗って遮集管3へ流入するため遮集効果がより高くなる。
【0013】
なお、本発明は図5Bその他に示すような従来の他の合流式下水道分水人孔に対しても同様に適用できる。
【0014】
【発明の効果】
上記のように本発明の排水装置用水面制御装置によれば、浮遊性の夾雑物5が遮集管3内に流入し易い流れが発生され、浮遊性夾雑物5の公共用水域への流出削減を行うことができるようになる大きな利益がある。
