(57) [Abstract] [PROBLEMS] The treatment of scum floating on the top of a flotation tank is simplified. SOLUTION: In a sewage pressure flotation device in which a scum scraping port 8 scraped off via a scraper 7 is opened in an upper part of a flotation separation tank 1 connected to a pressurizing tank 4, moisture is removed from the scum to the scum scraping port 8. It is characterized in that a dehydrating screen 9 for removing is provided.
Description
【０００１】[0001]
本考案は汚水の加圧浮上装置に関する。 The present invention relates to a sewage pressure floating device.
【０００２】[0002]
従来加圧タンクに連なる浮上分離槽の上部に、スクレパーを介して掻き取られ るスカム掻き取り口を開口した汚水の加圧浮上装置においては、スカム掻き取り 口から放出されるスカムを、処理装置によって処理している。 In the conventional levitation device for sewage that has a scum scraping opening that is scraped off via a scraper on the top of a flotation tank connected to a pressure tank, the scum discharged from the scum scraping opening is treated by a processing device. Processing.
【０００３】[0003]
このため処理装置はスカムのみならずスカム中に含まれる処理水の処理も行な わなければならず、その処理装置が膨大となって費用が嵩むと共にその処理場所 の確保も容易でない等の問題点があった。 本考案は、かかる問題点に対処するため開発されたものであってスカムの処理 を簡略化させることを目的とする。 For this reason, the treatment device has to treat not only scum but also the treated water contained in the scum, which causes an enormous amount of the treatment device and increases the cost, and it is not easy to secure the treatment place. There was a point. The present invention was developed to deal with such a problem, and an object thereof is to simplify the processing of scum.

上記の目的を達成するための本考案の構成は加圧タンクに連なる浮上分離槽の 上部にスクレパーを介して掻き取られるスカム掻き取り口を開口した汚水の加圧 浮上装置において、前記スカム掻き取り口に、スカムから水分を除去する脱水用 のスクリーンを設けたことを特徴とする。 In order to achieve the above object, the structure of the present invention is a sewage pressurization floating device with a scum scraping opening that is scraped off via a scraper at the top of a flotation tank connected to a pressure tank. A screen for dehydration is provided to remove water from the scum.

以下本考案の一実施例を図１〜図３に基づいて説明すると１は浮上分離槽を示 し、該浮上分離槽１の一側下部には汚水供給パイプ２を接続し、該汚水供給パイ プ２に圧力調整弁３を介して空気泡を噴出する加圧タンク４が設けられている。 又浮上分離槽１の上部にはスクレパー駆動部５を介して駆動されるチェーン６に 取り付けられて浮上分離槽１の上面に浮上するスカムを掻き取るスクレパー７が 設けられ、該スクレパー７を介して掻き取られるスカム掻き取り口８にはスカム から水分を除去するくさび形のワイヤを列設して形成したスクリーン９を設け、 該スクリーン９の下部に濾液出口１０を設けると共に該スクリーン９の端部にス カム出口１１を設けた。図中１２は加圧ポンプ、１３は加圧水流量計、１４はエ アー流量計、１５は濾液出口を示す。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a flotation separation tank, and a sewage supply pipe 2 is connected to a lower part of one side of the levitation separation tank 1 to connect the sewage supply pipe. A pressure tank 4 for ejecting air bubbles through a pressure regulating valve 3 is provided in the pump 2. Further, on the upper part of the levitation separation tank 1, there is provided a scraper 7 which is attached to a chain 6 driven by a scraper drive unit 5 and scrapes off the scum floating on the upper surface of the levitation separation tank 1. The scum scraping port 8 to be scraped off is provided with a screen 9 formed by arranging wedge-shaped wires for removing water from the scum, and a filtrate outlet 10 is provided below the screen 9 and at the end of the screen 9. A scum outlet 11 is provided. In the figure, 12 is a pressure pump, 13 is a pressurized water flow meter, 14 is an air flow meter, and 15 is a filtrate outlet.
【０００６】 かくて汚水供給ポンプ２を介して浮上分離槽１内に供給される汚水は加圧タン ク４からの空気泡によってそのスカムが浮上分離槽１の上面に浮上し、その浮上 したスカムはスクレパー７により掻き取られてスカム掻き取り口８よりスクリー ン９上に搬送され、該スクリーン９上でスカムに含まれる濾液はスクリーン９よ り落下して濾液出口１０より排出され、濾液を含まないスカムのみがスカム出口 １１より排出されるためスカムの処理装置が簡単となる。Thus, the sewage supplied into the levitation separation tank 1 via the sewage supply pump 2 has its scum floated on the upper surface of the levitation separation tank 1 by the air bubbles from the pressurized tank 4, and the floated scum. Is scraped off by the scraper 7 and conveyed from the scum scraping port 8 onto the screen 9, and the filtrate contained in the scum on the screen 9 falls from the screen 9 and is discharged from the filtrate outlet 10 and contains no filtrate. Since only the scum is discharged from the scum outlet 11, the scum processing device becomes simple.

上述したように本考案によるときは浮上分離槽の上部に開口するスカム掻き取 り口にスカムから水分を除去する脱水用のスクリーンを設けたものであるから、 スカムの水分は脱水用スクリーンによって除去されるためスカムの水分の除去が 簡単となりスカムの処理を簡略化させることができる効果を有する。 As described above, according to the present invention, the scum scrubbing opening that opens at the top of the flotation tank is provided with a dehydration screen that removes water from the scum. As a result, the removal of water from the scum is facilitated and the scum treatment can be simplified.
