It was not possible to release the water as is.
その対応策として、従来は別途、嫌気口座の後段に活性
汚泥法や好気口広を設けている。As a countermeasure, conventionally, activated sludge method and aerobic mouth widening were separately set up after the anaerobic account.

独立して維持する必要があり、隔壁等で水の流れを分断
し、混入し合わないようにするため、別途、処理槽外に
ポンプ等の移送設備が必要であった。(Problem to be solved by the invention) However, since the anaerobic treatment equipment and the aerobic treatment equipment are installed separately, there is a problem that the site area becomes large.
It is desired to develop a compact treatment device that integrates an anaerobic treatment device and an aerobic treatment device. In order to integrate an anaerobic treatment device and an aerobic treatment device, it is necessary to maintain the anaerobic and aerobic conditions of each separately, and to separate the flow of water with partitions etc. to prevent them from mixing. , transfer equipment such as a pump was required separately outside the treatment tank.
従って、本発明は、前記従来技術の欠点を屏消し、嫌気
処理装置と好気処理装置を一体化したコンパクトな処理
装置であって、有機性廃水を効率よく処理することがで
き、良好な処理水を得ることができる汚水処理装置を提
供することを目的とする。Therefore, the present invention eliminates the drawbacks of the prior art and provides a compact treatment device that integrates an anaerobic treatment device and an aerobic treatment device, which can efficiently treat organic wastewater and achieve good treatment. The purpose is to provide a sewage treatment device that can obtain water.
本発明は、嫌気口広上部に蛇行流を生じる液体流通口を
有し、発生ガスを集積できる隔壁を設けることによって
、嫌気口広の上部に好気口広を設置して一体化しても、
それぞれの口広を独立した条件に維持できることを確認
し、かかる知見に基づいて完成したものである。The present invention has a liquid flow port that generates a meandering flow in the upper part of the anaerobic wide opening, and by providing a partition wall that can collect the generated gas, even if the aerobic wide opening is installed and integrated at the upper part of the anaerobic wide opening,
It was confirmed that each mouth width could be maintained under independent conditions, and was completed based on this knowledge.

らの発生ガスを集積できる隔壁で区画され、該隔壁が液
体の蛇行流を生じる流通口を有することを特徴とする。That is, the sewage treatment apparatus according to the present invention includes an anaerobic port floor section having a wide-mouth material to which anaerobic microorganisms are attached, an oxygen-containing gas diffuser installed above the floor section, a floating port floor material, and a floating port floor material outflow. The anaerobic port floor and the aerobic port floor are separated by a partition wall that can collect the gas generated from the anaerobic port floor, and the partition wall is used to collect the gas generated from the anaerobic port floor. It is characterized by having a flow opening that generates a meandering flow.
このように、本発明の処理装置においては、嫌気口広を
上向流で通過した汚水を、嫌気口広上部の好気口床部を
酸素含有ガス散気のもとて短時間通過させることにより
、浮遊口床材の表面に付着した好気性微生物と接触させ
、良好な処理水が得られるように構成されている。As described above, in the treatment apparatus of the present invention, the wastewater that has passed through the anaerobic opening in an upward flow is allowed to pass through the aerobic opening floor above the anaerobic opening for a short time while being diffused with oxygen-containing gas. This system is configured to bring the floating mouth floor material into contact with aerobic microorganisms attached to the surface thereof, thereby obtaining good quality treated water.
