Description
本発明は、嫌気性微生物の生物膜を有する担体を用いて、食品工場の排水や下水等の有機性排水を生物学的に処理する担体嫌気処理装置の立ち上げ方法に関する。更に詳しくは、担体嫌気処理装置の立ち上げに際にて、担体表面における微生物膜の形成を促進して、担体嫌気処理装置を早期に立ち上げる方法に関するものである。 The present invention relates to a method for starting a carrier anaerobic treatment apparatus that biologically treats organic wastewater such as wastewater from a food factory or sewage using a carrier having a biofilm of anaerobic microorganisms. More specifically, the present invention relates to a method of accelerating the formation of a microbial film on the surface of a carrier and starting the carrier anaerobic treatment device at an early stage when the carrier anaerobic treatment device is started up.
食品工場の排水や下水等の有機性排水を処理する方法として、嫌気性微生物による生物処理が知られている。嫌気性微生物による生物処理は、メタンガスを回収することが可能であるため、広く産業排水の処理方法として普及している。 Biological treatment with anaerobic microorganisms is known as a method for treating organic wastewater such as wastewater and sewage from food factories. Biological treatment with anaerobic microorganisms is widely used as an industrial wastewater treatment method because it can recover methane gas.
従来、有機性排水を処理する方法として、固定床や流動床担体を使用する方法が適用されてきた。固定床担体を使用する方法は、生物膜を保持する担体を反応槽内部に固定し、その担体表面に形成された生物膜を利用して処理を行うものであり、流動床担体を使用する方法は、比重や大きさを調整した担体を反応槽内部で流動させて、その担体表面に形成された生物膜を用いて処理を行うものである。 Conventionally, a method using a fixed bed or a fluidized bed carrier has been applied as a method for treating organic wastewater. The method using a fixed bed carrier is a method in which a carrier holding a biofilm is fixed inside a reaction tank, and treatment is performed using a biofilm formed on the surface of the carrier. In this method, a carrier having a specific gravity and a size adjusted is caused to flow inside the reaction tank, and the treatment is performed using a biofilm formed on the surface of the carrier.
固定床担体、流動法担体を問わず、非生物担体を用いる場合には、担体への微生物の付着に時間がかかり、結果として装置の立ち上げに多大な時間を要するという欠点がある。従来、装置の立ち上げに際しては、担体を保持する反応槽内に分散状態の種汚泥を投入し、種汚泥が流出しないように通水量を抑えた条件で運転を行い、生物膜を担体表面に形成する。しかし、この方法では、装置の立ち上げに長期間を要していた。 When a non-biological carrier is used, regardless of whether it is a fixed bed carrier or a fluidized carrier, it takes time to attach microorganisms to the carrier, and as a result, it takes a long time to start up the apparatus. Conventionally, when starting up an apparatus, seed sludge in a dispersed state is introduced into a reaction tank holding a carrier, and the operation is performed under a condition that the water flow rate is suppressed so that the seed sludge does not flow out, and the biofilm is placed on the surface of the carrier. Form. However, this method requires a long time to start up the apparatus.
これに対して、特許文献１には、装置の立ち上げに要する時間を短縮する方法として、嫌気性処理槽に非生物担体とメタン菌グラニュールを所定の割合で添加し、運転開始初期のみメタン菌グラニュールを存在させ、その後はメタン菌グラニュールを解体、分散化させるように運転する方法が記載されている。 On the other hand, in Patent Document 1, as a method for shortening the time required for starting up the apparatus, a non-biological carrier and methane bacterium granules are added to the anaerobic treatment tank at a predetermined ratio, and methane is added only at the initial stage of operation. A method is described in which fungal granules are present and then operated to disassemble and disperse the methane granules.
本発明は、担体を用いて嫌気処理を行う担体嫌気処理装置の立ち上げ方法において、担体表面に付着した微生物の増殖を促進し、担体表面への生物膜の形成に要する時間を短縮することを目的とする。 The present invention relates to a method for starting up a carrier anaerobic treatment apparatus that performs anaerobic treatment using a carrier, by promoting the growth of microorganisms attached to the carrier surface and reducing the time required for forming a biofilm on the carrier surface. Objective.
本発明者は、上記の課題について鋭意検討した結果、担体嫌気性処理装置の立ち上げに際して、担体表面に生物膜を形成する工程と、被処理水を嫌気処理する工程を別々の槽で行うことにより、担体表面への生物膜の形成に要する時間が短縮されることを見出して、本発明を完成した。
具体的には、以下の担体嫌気処理装置の立ち上げ方法又は担体嫌気処理立ち上げ装置である。
As a result of earnestly examining the above problems, the inventor performs a process of forming a biofilm on the surface of the carrier and a process of anaerobically treating the water to be treated in separate tanks when the carrier anaerobic treatment apparatus is started up. Thus, it was found that the time required for forming a biofilm on the surface of the carrier was shortened, and the present invention was completed.
Specifically, it is the following method for starting up a carrier anaerobic treatment apparatus or carrier anaerobic treatment start-up apparatus.
上記課題を解決するための本発明の担体嫌気処理装置の立ち上げ方法とは、担体を用いて嫌気処理を行う担体嫌気処理装置の立ち上げ方法において、担体を保持した担体処理槽に被処理水を通水し、該担体表面に生物膜を形成する工程と、前記担体処理槽から流出した第１処理水を嫌気処理槽に通水し、該第１処理水を嫌気処理する工程と、を備えたことを特徴とする。 The start-up method of the carrier anaerobic treatment apparatus of the present invention for solving the above-mentioned problem is the start-up method of the carrier anaerobic treatment apparatus that performs the anaerobic treatment using the carrier, in the carrier treatment tank holding the carrier, Passing water and forming a biofilm on the surface of the carrier; and passing the first treated water flowing out of the carrier treatment tank through an anaerobic treatment tank and anaerobically treating the first treated water. It is characterized by having.
従来の担体嫌気処理装置の立ち上げ方法では、担体と種汚泥を一つの槽に保持して種汚泥を担体表面に付着させ、その後、担体表面に生物膜を形成するまで時間をかけて生育する。担体表面に付着した微生物の増殖には、被処理水に含まれる有機物が基質として利用されている。
しかし、従来の立ち上げ方法によれば、担体表面に付着しない浮遊菌も増殖するため、浮遊菌が徐々に高い処理能力を有するようになる。そうすると、処理能力の高い浮遊菌が有機物を優先的に処理してしまい、担体表面に付着した微生物の増殖を妨げる原因となる。
In the conventional method for starting up the carrier anaerobic treatment apparatus, the carrier and the seed sludge are held in one tank, the seed sludge is attached to the surface of the carrier, and then it takes time until a biofilm is formed on the surface of the carrier. . For the growth of microorganisms attached to the surface of the carrier, organic substances contained in the water to be treated are used as a substrate.
However, according to the conventional start-up method, the floating bacteria that do not adhere to the surface of the carrier also grow, so that the floating bacteria gradually have a high treatment capacity. If it does so, an airborne microbe with high processing capacity will process organic matter preferentially, and will cause the growth of the microorganisms adhering to the support | carrier surface.
これに対して、本発明の担体嫌気処理装置の立ち上げ方法によると、担体表面に生物膜を形成する工程と、被処理水を嫌気処理する工程を、それぞれ別の槽で行うため、担体表面に付着した微生物の増殖が処理能力の高い浮遊菌により阻害されることがない。また、嫌気処理槽の前段に担体処理槽を設けることにより、基質となる有機物を十分に含む被処理水が担体を通過するため、担体表面における微生物の生育を促進することができる。よって、本発明の立ち上げ方法によれば、担体表面への生物膜の形成に要する時間が短縮され、担体嫌気処理装置の早期立ち上げが可能となる。 On the other hand, according to the method for starting up the carrier anaerobic treatment apparatus of the present invention, the step of forming a biofilm on the surface of the carrier and the step of anaerobically treating the water to be treated are performed in separate tanks. The growth of microorganisms adhering to the surface is not hindered by suspended bacteria with high processing ability. In addition, by providing the carrier treatment tank in the preceding stage of the anaerobic treatment tank, the water to be treated that sufficiently contains the organic substance serving as the substrate passes through the carrier, so that the growth of microorganisms on the surface of the carrier can be promoted. Therefore, according to the start-up method of the present invention, the time required for forming a biofilm on the surface of the carrier is shortened, and the carrier anaerobic treatment apparatus can be started up early.
また、特許文献１に記載された発明のように、担体とグラニュール汚泥を混合して嫌気処理の立ち上げを行う場合には、グラニュール汚泥は種汚泥として添加され、その添加量には制限がある。そのため、被処理水を所定の水質まで処理するには、グラニュール汚泥自体の処理能力だけでは足りず、担体表面への生物膜の形成をある程度待ってから被処理水の通水量を高める必要があった。
一方、本発明の立ち上げ方法では、嫌気処理槽における嫌気処理工程によって、被処理水を所定の水質まで処理することができるため、担体表面に生物膜を形成する工程を開始すると同時に、すぐに被処理水の通水量を高めることができる。
Moreover, like the invention described in Patent Document 1, when anaerobic treatment is started by mixing a carrier and granule sludge, the granule sludge is added as seed sludge, and the amount of addition is limited. There is. Therefore, in order to treat the water to be treated to a predetermined quality, the treatment capacity of the granular sludge itself is not sufficient, and it is necessary to wait for a certain amount of biofilm to form on the carrier surface before increasing the amount of water to be treated. there were.
On the other hand, in the start-up method of the present invention, since the water to be treated can be treated up to a predetermined water quality by the anaerobic treatment step in the anaerobic treatment tank, immediately after starting the step of forming a biofilm on the surface of the carrier. The amount of water to be treated can be increased.
更に本発明の担体嫌気処理装置の立ち上げ方法は、第１処理水を嫌気処理する工程において、グラニュール汚泥を使用するという特徴を有する。
第１処理水を嫌気処理する際、第１処理水は、上向流により微生物の層を通って処理され、嫌気処理槽の上部から第２処理水として流出する。ここで、嫌気処理に使用する微生物として比重の小さいスラリー状の汚泥を使用すると、多量の汚泥が第２処理水と共に流出するため、沈殿槽等の分離手段により、処理水と汚泥を分離する必要がある。
一方、グラニュール汚泥は比重が大きく、嫌気処理槽からの流出が少ないため、分離手段等を設けなくても嫌気処理を行うことが可能となり、省スペース性に優れた担体嫌気処理立ち上げ方法を実施することができる。
Furthermore, the method for starting up the carrier anaerobic treatment apparatus of the present invention is characterized in that granule sludge is used in the step of anaerobically treating the first treated water.
When anaerobically treating the first treated water, the first treated water is treated through the microorganism layer by upward flow, and flows out from the upper part of the anaerobic treatment tank as the second treated water. Here, if slurry sludge having a small specific gravity is used as a microorganism used for anaerobic treatment, a large amount of sludge flows out together with the second treated water, so it is necessary to separate the treated water and sludge by a separation means such as a sedimentation tank. There is.
On the other hand, granule sludge has a large specific gravity and little outflow from the anaerobic treatment tank, making it possible to perform anaerobic treatment without providing separation means etc. Can be implemented.
更に本発明の担体嫌気処理装置の立ち上げ方法は、嫌気処理槽から流出した第２処理水の一部を、担体処理槽に返送する工程を有する。
この工程によれば、嫌気処理槽から流出した微生物を種菌として、担体処理槽に投入することができるため、担体表面への生物膜の形成を更に促進することができる。また、返送量を調整することにより、担体処理槽中の微生物量が調整されるため、担体表面に付着した微生物の生育環境を良好な状態に整えることができる。
Furthermore, the method for starting up the carrier anaerobic treatment apparatus of the present invention includes a step of returning a part of the second treated water flowing out from the anaerobic treatment tank to the carrier treatment tank.
According to this step, since the microorganisms that have flowed out of the anaerobic treatment tank can be introduced into the carrier treatment tank as seed bacteria, the formation of a biofilm on the surface of the carrier can be further promoted. Moreover, since the amount of microorganisms in the carrier treatment tank is adjusted by adjusting the return amount, the growth environment of microorganisms attached to the surface of the carrier can be adjusted to a good state.
また、本発明の担体嫌気処理立ち上げ装置は、担体を用いて被処理水を嫌気処理する担体嫌気処理装置の後段に設けられ、該担体嫌気処理装置から流出した第１処理水を嫌気処理するという特徴を有する。
この担体嫌気処理立ち上げ装置によれば、上記担体嫌気処理立ち上げ方法と同様、担体表面への生物膜の形成に要する時間が短縮され、担体嫌気処理装置の早期立ち上げを可能とする。
Further, the carrier anaerobic treatment start-up device of the present invention is provided at the subsequent stage of the carrier anaerobic treatment device for anaerobically treating the water to be treated using the carrier, and anaerobically treats the first treated water flowing out from the carrier anaerobic treatment device. It has the characteristics.
According to this carrier anaerobic treatment start-up device, the time required for the formation of a biofilm on the surface of the carrier is shortened as in the case of the carrier anaerobic treatment start-up method, and the carrier anaerobic treatment device can be started up early.
本発明の担体嫌気処理装置の立ち上げ方法及び担体嫌気処理立ち上げ装置によると、担体表面への生物膜の形成に要する時間が短縮され、担体嫌気処理装置を早期に立ち上げることができる。 According to the carrier anaerobic treatment apparatus start-up method and carrier anaerobic treatment start-up apparatus of the present invention, the time required to form a biofilm on the surface of the carrier can be shortened, and the carrier anaerobic treatment apparatus can be started up early.
以下に、本発明の担体嫌気処理装置の立ち上げ方法及び担体嫌気処理立ち上げ装置について説明する。なお、本明細書において、担体嫌気処理装置の立ち上げ方法の各構成、又は、担体嫌気処理立ち上げ装置の各構成についての説明は、それぞれ対応する立ち上げ装置の構成、又は、立ち上げ方法の構成についても説明されているものとする。 The carrier anaerobic treatment apparatus startup method and carrier anaerobic treatment startup apparatus of the present invention will be described below.

以下では、この発明の実施形態を、添付図面を参照して詳細に説明する。
［第１の実施態様］
図１は、担体嫌気処理装置１と、担体嫌気処理装置１の立ち上げ方法を実施するための第１の実施態様の担体嫌気処理立ち上げ装置２を示す概略説明図である。
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[First Embodiment]
FIG. 1 is a schematic explanatory view showing a carrier anaerobic treatment apparatus 1 and a carrier anaerobic treatment start-up apparatus 2 of a first embodiment for carrying out a method for starting up the carrier anaerobic treatment apparatus 1.
担体嫌気処理装置１は、担体処理槽１ａを備えており、担体嫌気処理装置１を立ち上げるに際して該担体処理槽１ａに、生物膜が形成されていない非生物担体が投入される。そして、本発明の担体嫌気処理装置の立ち上げ方法により該担体表面に生物膜が形成されると、担体嫌気処理装置１を用いて被処理水Ｗ０を所定の水質となるまで処理することが可能となり、本発明の立ち上げ方法は終了する。 The carrier anaerobic treatment apparatus 1 includes a carrier treatment tank 1a. When the carrier anaerobic treatment apparatus 1 is started up, a non-biological carrier on which a biofilm is not formed is charged into the carrier treatment tank 1a. Then, when a biofilm is formed on the surface of the carrier by the method for starting the carrier anaerobic treatment apparatus of the present invention, the treated water W0 can be treated using the carrier anaerobic treatment apparatus 1 until the water quality reaches a predetermined level. This completes the start-up method of the present invention.
担体処理槽１ａは、底部に被処理水Ｗ０を供給するためのラインＬ１、上部に担体処理槽１ａを通水した第１処理水Ｗ１を排出するためのラインＬ２を有している。また、本発明の担体嫌気処理装置の立ち上げ方法を実施するにあたって、担体嫌気処理立ち上げ装置２が担体処理槽１ａと隣接して設置され、ラインＬ２は該担体嫌気処理立ち上げ装置２の嫌気処理槽２ａの底部に連結されている。 The carrier treatment tank 1a has a line L1 for supplying the treated water W0 to the bottom, and a line L2 for discharging the first treated water W1 that has passed through the carrier treatment tank 1a at the top. In carrying out the method for starting up the carrier anaerobic treatment apparatus of the present invention, the carrier anaerobic treatment start-up apparatus 2 is installed adjacent to the carrier treatment tank 1a, and the line L2 is anaerobic of the carrier anaerobic treatment start-up apparatus 2. It is connected to the bottom of the processing tank 2a.
このような装置構成により、本発明の担体嫌気処理装置１の立ち上げ方法では、被処理水Ｗ０を担体処理槽１ａに通水し、担体表面に生物膜を形成する。そして、担体表面に生物膜が形成されるまでの期間は、第１処理水Ｗ１の処理が不十分な状態であるため、後段に設置された担体嫌気処理立ち上げ装置２において、所定の水質になるまで嫌気処理が行われる。 With such an apparatus configuration, in the start-up method of the carrier anaerobic treatment apparatus 1 of the present invention, the water to be treated W0 is passed through the carrier treatment tank 1a to form a biofilm on the surface of the carrier. The period until the biofilm is formed on the surface of the carrier is in a state where the treatment of the first treated water W1 is inadequate, so that the carrier anaerobic treatment start-up device 2 installed at the subsequent stage has a predetermined water quality. Anaerobic processing is performed until it becomes.
この立ち上げ方法によれば、担体表面に生物膜を形成する工程と、被処理水を嫌気処理する工程を、それぞれ別の槽で行うため、処理能力の高い微生物により担体表面に付着した微生物の増殖が阻害されない。また、基質となる有機物を十分に含む被処理水Ｗ０が担体処理槽１ａを通過するため、担体表面における微生物の生育を促進することができる。
更に、嫌気処理槽２ａにおける嫌気処理工程によって、被処理水Ｗ０を所定の水質まで処理することができるため、担体表面に生物膜を形成する工程を開始すると同時に、すぐに被処理水Ｗ０の通水量を高めることができるという効果もある。
According to this start-up method, the step of forming a biofilm on the surface of the carrier and the step of anaerobically treating the water to be treated are performed in separate tanks. Growth is not inhibited. Moreover, since the to-be-processed water W0 fully containing the organic substance used as a substrate passes the support | carrier process tank 1a, the growth of the microorganisms on the support | carrier surface can be accelerated | stimulated.
Furthermore, since the water to be treated W0 can be treated to a predetermined water quality by the anaerobic treatment step in the anaerobic treatment tank 2a, the process of forming a biofilm on the surface of the carrier is started and at the same time, the water to be treated W0 is passed. There is also an effect that the amount of water can be increased.
本発明の担体嫌気処理装置１の立ち上げ方法は、担体処理槽１ａに充填された担体の表面に生物膜が形成され、所定の水質まで処理することが可能となれば終了となる。立ち上げ方法の終了の判断手法は、特に制限されないが、例えば、目視による生物膜の形成の確認や、第１処理水Ｗ１の水質の検出等により判断することができる。担体嫌気処理装置１の嫌気処理能力を確認するという観点から、第１処理水Ｗ１の水質を検出することにより、立ち上げ終了の判断を行うことが好ましい。また、検出する水質の項目としては、例えば、化学的酸素要求量（Chemical Oxygen Demand：ＣＯＤ）や生物化学的酸素要求量（Biochemical Oxygen Demand：ＢＯＤ）等が挙げられる。素早く判断できるという観点から、測定時間が短いＣＯＤを利用することが好ましい。 The start-up method of the carrier anaerobic treatment apparatus 1 according to the present invention ends when a biofilm is formed on the surface of the carrier filled in the carrier treatment tank 1a and treatment to a predetermined water quality is possible. The method for determining the end of the start-up method is not particularly limited, and can be determined by, for example, confirming the formation of a biofilm visually or detecting the water quality of the first treated water W1. From the viewpoint of confirming the anaerobic treatment capability of the carrier anaerobic treatment device 1, it is preferable to determine the start-up end by detecting the water quality of the first treated water W1. Examples of water quality items to be detected include chemical oxygen demand (COD) and biochemical oxygen demand (BOD). From the viewpoint of being able to make a quick decision, it is preferable to use a COD with a short measurement time.
立ち上げ終了後の担体嫌気処理立ち上げ装置２の取り扱いについては、特に制限されないが、例えば、取り外して別の担体嫌気処理装置の立ち上げ等に利用することができる。 Handling of the carrier anaerobic treatment start-up device 2 after completion of the start-up is not particularly limited. For example, the carrier anaerobic treatment start-up device 2 can be removed and used for starting up another carrier anaerobic processing device.
ここで、本発明の担体嫌気処理立ち上げ装置２について更に詳細に説明する。
担体嫌気処理立ち上げ装置２は、嫌気処理槽２ａを備えた装置であり、嫌気処理槽２ａは、担体嫌気処理装置１の立ち上げの際に、嫌気処理が不十分な状態で担体処理槽１ａを流出した第１処理水Ｗ１を所定の水質にまで嫌気処理する構成である。なお、所定の水質は、排水基準や、次工程の処理等に応じて適宜設定される。
Here, the carrier anaerobic treatment start-up device 2 of the present invention will be described in more detail.
The carrier anaerobic treatment start-up device 2 is an apparatus provided with an anaerobic treatment tank 2a, and the anaerobic treatment tank 2a is in a state where the anaerobic treatment is insufficient when the carrier anaerobic treatment device 1 is started up. It is the structure which anaerobically treats the 1st treated water W1 which flowed out to predetermined water quality. The predetermined water quality is appropriately set according to drainage standards, processing in the next process, and the like.
第１の実施例の担体嫌気処理立ち上げ装置２において、嫌気処理槽２ａには、嫌気性微生物としてメタン生成菌を有するグラニュール汚泥が含まれる。
なお、嫌気処理槽２ａにおける嫌気処理に利用される嫌気性微生物は、被処理水Ｗ０に対して行う嫌気処理に合わせて適宜選択され、例えば、有機物を分解してメタンを生成するメタン生成菌や、硝酸・亜硝酸等を窒素に還元する脱窒菌、硫酸等を還元する硫酸還元菌、水素イオンの還元を行う水素生成菌等が挙げられる。メタンを燃料等に再利用できることから、メタン生成菌による生物処理が好ましい。
In the carrier anaerobic treatment start-up device 2 of the first embodiment, the anaerobic treatment tank 2a contains granule sludge having methanogenic bacteria as anaerobic microorganisms.
In addition, the anaerobic microorganisms utilized for the anaerobic treatment in the anaerobic treatment tank 2a are appropriately selected according to the anaerobic treatment performed on the water to be treated W0. For example, a methane-producing bacterium that decomposes organic substances to produce methane, And denitrifying bacteria that reduce nitric acid, nitrous acid, and the like to nitrogen, sulfate-reducing bacteria that reduce sulfuric acid, and the like, and hydrogen-producing bacteria that reduce hydrogen ions. Since methane can be reused as fuel, biological treatment with methanogenic bacteria is preferable.
嫌気処理槽２ａにおける嫌気処理の方法は特に限定されず、例えば、浮遊菌により形成されるスラリー状の汚泥を使用する方法、固定床担体、流動床担体等のように生物膜が形成された担体を使用する方法、ＵＡＳＢ（Upflow Anaerobic Sludge Blanket）法、ＥＧＳＢ（Expanded Granule Sludge Blanket）法等のようにグラニュール汚泥を使用する方法等が挙げられる。 The method of anaerobic treatment in the anaerobic treatment tank 2a is not particularly limited, for example, a method using slurry sludge formed by floating bacteria, a carrier on which a biofilm is formed such as a fixed bed carrier, a fluidized bed carrier and the like. And a method using granular sludge such as UASB (Upflow Anaerobic Sludge Blanket) method and EGSB (Expanded Granule Sludge Blanket) method.
スラリー状の汚泥を使用する方法によれば、特殊な微生物を利用することがなく、汎用性に優れるが、浮遊菌の比重が小さいため、浮遊菌が大量に第２処理水Ｗ２と共に流出する恐れがある。そのため、嫌気処理槽２ａを大きくするか、沈降槽等の固液分離手段を設ける必要があり、担体嫌気処理立ち上げ装置２が長大化する。 According to the method using slurry sludge, it does not use special microorganisms and is excellent in generality. There is. Therefore, it is necessary to enlarge the anaerobic treatment tank 2a or to provide solid-liquid separation means such as a sedimentation tank, and the carrier anaerobic treatment start-up device 2 becomes longer.
これに対して、生物膜が形成された担体を使用する方法や、グラニュール汚泥を使用する方法は、微生物の流出が抑制されるため、省スペース性に優れた立ち上げ方法を実施することができる。処理能力が高く、さらに省スペース化に優れるという観点から、グラニュール汚泥を使用する方法が好ましい。 On the other hand, the method of using a carrier on which a biofilm is formed and the method of using granule sludge suppress the outflow of microorganisms, and therefore, it is possible to implement a start-up method excellent in space saving. it can. From the viewpoint of high processing capability and excellent space saving, a method using granular sludge is preferable.
嫌気処理槽２ａで嫌気処理された第２処理水は、嫌気処理槽２ａの上部に設けられたラインＬ３より流出し、系外へ排出される。なお、第２処理水は、必要に応じて固液分離等の処理を行ってもよい。
なお、嫌気処理槽２ａに第１処理水Ｗ１を通水する際、嫌気処理槽２ａに形成される流れ方向は特に制限されず、第１処理水Ｗ１が所定の水質にまで嫌気処理される構成であればよい。例えば、第１の実施態様のように上向流を形成する他、下向流と形成してもよい。第１処理水Ｗ１の流入部および流出部を構成するラインＬ２およびＬ３の設置場所については、第１処理水Ｗ１の流れ方向に応じて、適切に設計すればよい。
The second treated water that has been anaerobically treated in the anaerobic treatment tank 2a flows out of the line L3 provided at the upper part of the anaerobic treatment tank 2a and is discharged out of the system. The second treated water may be subjected to treatment such as solid-liquid separation as necessary.
When flowing the first treated water W1 to the anaerobic treatment tank 2a, the flow direction formed in the anaerobic treatment tank 2a is not particularly limited, and the first treated water W1 is anaerobically treated to a predetermined water quality. If it is. For example, in addition to forming an upward flow as in the first embodiment, a downward flow may be formed. What is necessary is just to design appropriately about the installation place of the lines L2 and L3 which comprise the inflow part and outflow part of the 1st treated water W1 according to the flow direction of the 1st treated water W1.
また、ラインＬ３は分岐して、第２処理水Ｗ２の一部を担体処理槽１ａに返送するための返送ラインＬ４が形成されている。
第２処理水Ｗ２には、グラニュールから剥離した比重の小さい浮遊菌が含まれるため、担体処理槽１ａに返送することにより、担体表面に付着する微生物の種菌として利用することができる。
Further, the line L3 is branched to form a return line L4 for returning a part of the second treated water W2 to the carrier treatment tank 1a.
Since the second treated water W2 contains floating bacteria having a small specific gravity separated from the granules, the second treated water W2 can be used as a seed for microorganisms attached to the surface of the carrier by returning it to the carrier treatment tank 1a.
ここで、第２処理水Ｗ２の返送量としては、特に制限されないが、被処理水の流量１００に対して１〜９０であり、好ましくは５〜５０であり、特に好ましくは１０〜３０である。１未満の場合、種菌が少なく、担体表面における微生物の付着量が低下し、９０を超える場合には、種菌が多くなり、担体表面に付着した微生物の増殖を抑制する恐れがある。 Here, the return amount of the second treated water W2 is not particularly limited, but is 1 to 90, preferably 5 to 50, particularly preferably 10 to 30 with respect to the flow rate 100 of the water to be treated. . If the number is less than 1, the number of inoculums is small and the amount of microorganisms attached to the surface of the carrier decreases. If the number exceeds 90, the number of inoculums increases and the growth of microorganisms attached to the surface of the carrier may be suppressed.

第２の実施態様の担体嫌気処理装置３と担体嫌気処理立ち上げ装置４は、一つの槽を仕切り壁Ｄにより担体処理槽３ａと嫌気処理槽４ａに区分けすることにより構成されている。
[Second Embodiment]
FIG. 2 is a schematic explanatory diagram showing the carrier anaerobic treatment device 3 and the carrier anaerobic treatment startup device 4 of the second embodiment for implementing the startup method of the carrier anaerobic processing device 3.
The carrier anaerobic treatment device 3 and the carrier anaerobic treatment start-up device 4 of the second embodiment are configured by dividing one tank into a carrier treatment tank 3a and an anaerobic treatment tank 4a by a partition wall D.
第２の実施態様において、被処理水Ｗ０を供給するためのラインＬ１は、担体処理槽３ａの略中央の上部に設置されている。担体処理槽３ａの略中央部の上部から流入した被処理水Ｗ０は、担体処理槽３ａの中央部において下方に向かう流れを形成し、底面に衝突して担体処理槽３ａの壁面方向へと広がり、壁面に沿って上昇するという循環流を形成する。その際、被処理水Ｗ０が底面に沈降する粒状担体を通過して、担体処理槽３ａの上方の壁に設けられたラインＬ２から第１処理水Ｗ１として流出する。 In the second embodiment, the line L1 for supplying the water to be treated W0 is installed at the upper part of the substantially center of the carrier treatment tank 3a. The water to be treated W0 flowing from the upper part of the substantially central part of the carrier treatment tank 3a forms a downward flow in the central part of the carrier treatment tank 3a, collides with the bottom surface and spreads in the direction of the wall surface of the carrier treatment tank 3a. Forms a circulating flow that rises along the wall surface. In that case, the to-be-processed water W0 passes the granular support | carrier which settles to a bottom face, and flows out as 1st process water W1 from the line L2 provided in the upper wall of the support | carrier process tank 3a.
このように、第２の実施態様の担体嫌気処理装置３において、担体処理槽３ａに流入した被処理水Ｗ０は循環流を形成しているが、担体処理槽３ａに形成される被処理水Ｗ０の流れ方向は、特に制限されず、被処理水Ｗ０が担体処理槽内に保持された非生物担体を通過するように構成すればよい。例えば、第１の実施態様のような上向流を形成しても、下向流を形成してもよい。 Thus, in the carrier anaerobic treatment device 3 of the second embodiment, the water to be treated W0 flowing into the carrier treatment tank 3a forms a circulating flow, but the water to be treated W0 formed in the carrier treatment tank 3a. The flow direction is not particularly limited, and it may be configured such that the water to be treated W0 passes through the non-biological carrier held in the carrier treatment tank. For example, an upward flow as in the first embodiment may be formed, or a downward flow may be formed.
また、嫌気処理槽４ａから流出した第２処理水Ｗ２の一部は、返送ラインＬ４を通って、担体処理槽３ａの略中央の上部から返送され、被処理水Ｗ０の循環流に合流する。
なお、ラインＬ１、Ｌ２、返送ラインＬ４の設置場所については、被処理水Ｗ０の流れ方向に応じて、適切に設計すればよい。
Further, a part of the second treated water W2 flowing out from the anaerobic treatment tank 4a passes through the return line L4 and is returned from the upper part at the substantially center of the carrier treatment tank 3a, and joins the circulating flow of the treated water W0.
In addition, what is necessary is just to design suitably about the installation place of line L1, L2, and the return line L4 according to the flow direction of the to-be-processed water W0.
第２の実施態様の担体嫌気処理立ち上げ装置４において、仕切り壁Ｄは垂直方向に設置しているが、仕切り壁Ｄの設置方向は、特に制限されず、例えば、仕切り壁Ｄを水平方向に設け、担体処理槽と嫌気処理槽を上下方向に配置してもよい。 In the carrier anaerobic treatment start-up device 4 of the second embodiment, the partition wall D is installed in the vertical direction, but the installation direction of the partition wall D is not particularly limited. For example, the partition wall D is placed in the horizontal direction. The carrier treatment tank and the anaerobic treatment tank may be provided in the vertical direction.
また、仕切り壁Ｄは、取り外し可能な構成としてもよい。仕切り壁Ｄを取り外し可能な構成とすることにより、担体嫌気処理装置３の立ち上げ終了後に仕切り壁Ｄを取り外して、一つの担体嫌気処理装置として使用することもできる。 Moreover, the partition wall D is good also as a structure which can be removed. By making the partition wall D removable, the partition wall D can be detached after the start of the start of the carrier anaerobic treatment device 3 and used as one carrier anaerobic treatment device.
第２の実施態様では、担体処理槽３ａと嫌気処理槽４ａをラインＬ２により連結しているが、仕切り壁Ｄに連通口を設けてもよい。 In the second embodiment, the carrier treatment tank 3a and the anaerobic treatment tank 4a are connected by a line L2, but a communication port may be provided in the partition wall D.

第３の実施態様の担体嫌気処理立ち上げ装置６は、嫌気処理槽６ａと沈降槽６ｂを備え、嫌気処理槽６ａには、浮遊菌により形成されるスラリー状の汚泥が保持されている。
[Third Embodiment]
FIG. 3 is a schematic explanatory diagram showing the carrier anaerobic treatment device 5 and the carrier anaerobic treatment startup device 6 of the third embodiment for implementing the startup method of the carrier anaerobic processing device 5.
The carrier anaerobic treatment start-up device 6 of the third embodiment includes an anaerobic treatment tank 6a and a sedimentation tank 6b, and slurry-like sludge formed by floating bacteria is held in the anaerobic treatment tank 6a.
担体嫌気処理立ち上げ装置６では、嫌気処理槽６ａにて嫌気処理された第２処理水Ｗ２は、沈降槽６ｂに流入し、沈降分離により第３処理水Ｗ３と返送汚泥Ｓ１に分離される。第３処理水は、沈降槽６ｂの上部に形成されたラインＬ３より流出して、系外に排出される。 In the carrier anaerobic treatment start-up device 6, the second treated water W2 subjected to the anaerobic treatment in the anaerobic treatment tank 6a flows into the settling tank 6b, and is separated into the third treated water W3 and the return sludge S1 by sedimentation separation. The third treated water flows out from the line L3 formed in the upper part of the settling tank 6b and is discharged out of the system.
返送汚泥Ｓ１は、返送ラインＬ４を介して担体処理槽５ａに返送され、担体表面に付着する種菌として利用される。
また、返送ラインＬ４は分岐しており、一方を担体処理槽５ａに、他方をラインＬ２に連結している。そして、返送汚泥Ｓ１の一部が担体処理槽５ａに返送され、残部は嫌気処理槽６ａに返送される。嫌気処理槽６ａに返送することにより、嫌気処理槽６ａの微生物の減少を抑制し、嫌気処理を維持することができる。
The return sludge S1 is returned to the carrier treatment tank 5a via the return line L4 and used as an inoculum that adheres to the surface of the carrier.
The return line L4 is branched, and one is connected to the carrier processing tank 5a and the other is connected to the line L2. A part of the returned sludge S1 is returned to the carrier treatment tank 5a, and the remaining part is returned to the anaerobic treatment tank 6a. By returning to the anaerobic treatment tank 6a, the reduction of microorganisms in the anaerobic treatment tank 6a can be suppressed and the anaerobic treatment can be maintained.
返送汚泥Ｓ１を担体処理槽５ａと嫌気処理槽６ａに分岐して返送する量の割合は、返送汚泥Ｓ１の濃縮の程度により適宜決定されるが、返送汚泥Ｓ１の全量１００に対する担体処理槽５ａへの返送量が０．１〜５０となるように調整する。好ましくは、０．５〜３０であり、更に好ましくは、１〜１０である。０．１未満の場合には、種菌が少なく、担体表面における微生物の付着量が低下し、５０を超える場合には、種菌が多くなり、担体表面に付着した微生物の増殖を抑制する恐れがある。 The ratio of the amount of return sludge S1 branched and returned to the carrier treatment tank 5a and the anaerobic treatment tank 6a is appropriately determined depending on the degree of concentration of the return sludge S1, but to the carrier treatment tank 5a for the total amount 100 of the return sludge S1. The return amount is adjusted to be 0.1-50. Preferably, it is 0.5-30, More preferably, it is 1-10. If it is less than 0.1, the number of inoculums is small, and the amount of microorganisms attached to the surface of the carrier decreases. If it exceeds 50, the number of inoculums increases, and the growth of microorganisms attached to the surface of the carrier may be suppressed. .
