Title (EN) FLOCCULATION TREATMENT APPARATUS AND FLOCCULATION TREATMENT METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT DE FLOCULATION
(JA) 凝集処理装置及び凝集処理方法
Abstract: front page image
(EN)A flocculation treatment apparatus (1) which is provided with: a flocculation treatment apparatus main body (20) that comprises a cylindrical flocculation tank into which water to be processed is introduced, a feed port for water to be processed through which the water to be processed is introduced into the flocculation tank in a tangential direction so as to create a swirling flow, and a discharge port for water to be processed through which the water to be processed is discharged in a tangential direction; a first valve (34) which is provided in the upstream of the feed port for water to be processed and the opening degree of which is variable; and a first valve flow rate adjusting means which is capable of adjusting the flow rate of the water to be processed passing through the first valve (34) independently from the changes of the flow rate of the water to be processed passing through the first valve (34) caused by changing the opening degree of the first valve (34).
(FR)L'invention concerne un dispositif de floculation (1) qui est muni : d'un corps principal de dispositif de floculation (20) qui possède un bassin de floculation de forme cylindrique dans lequel une eau à traiter est introduite, une ouverture d'introduction d'eau à traiter qui introduit l'eau à traiter dans le bassin de floculation dans une direction tangente de manière à produire un flux tourbillonnaire, et une ouverture de décharge d'eau à traiter qui décharge l'eau à traiter dans la direction tangente; d'une première valve (34) qui est agencée en amont de l'ouverture d'introduction d'eau à traiter, et dont le degré d'ouverture est variable; et d'un moyen de régulation de débit de première valve qui permet de réguler le débit de l'eau à traiter qui passe au travers de la première valve (34) indépendamment des variations de débit de l'eau à traiter qui passe au travers de la première valve (34) du fait de la variation du degré d'ouverture de la première valve (34).
(JA)被処理水が導入される円筒形状の凝集槽、旋回流が発生するように被処理水を接線方向に凝集槽に導入する被処理水導入口、及び、被処理水を接線方向に排出する被処理水排出口を有する凝集処理装置本体20と、被処理水導入口の上流に設けられ、開度が可変な第1のバルブ34と、第1のバルブ34の開度の変化による第1のバルブ34を通過する被処理水の流量変化とは独立して第1のバルブ34を通過する被処理水の流量を調整できる第1のバルブ流量調整手段とを具備する凝集処理装置1とする。
