【発明の属する技術分野】
本発明は、合併処理化装置に関する。
【0002】
【従来の技術】
従来から、屎尿の浄化を行う装置としては、単独処理浄化槽を用いている。図5は、分離接触ばっ気方式の単独処理浄化槽を示す概略断面図である。屎尿は、流入口2から沈殿分離室3へと流入し、固液分離及び嫌気処理が行われ、接触ばっ気室4へと移流する。接触ばっ気室4内では、移流した水が散気管7から散気される空気の泡により攪拌されて接触材8に接触し、栄養基質の酸化除去が徐々に行われる。接触材8は、攪拌を継続していると生物膜が厚く堆積し閉塞するので、定期的に逆洗管9より空気泡を吐出することで生物膜を剥離させる。接触ばっ気室4を通過した水は、沈殿室5にて固形分の沈殿分離を行ってから、分離した上澄み液を消毒室6へと移流させ、滅菌処理を施した後に流出口10より放流される。
【0003】
【発明が解決しようとする課題】
しかしながら、単独処理浄化槽は、処理すべき水の種類が屎尿に限定され、台所排水、洗濯排水、洗面排水及び浴槽排水等の生活雑排水を処理できないとの課題を有している。このような問題は、既設の単独処理浄化槽を撤去して新たに合併処理浄化槽を設置することで解決できるが、施工費用が高額となるばかりでなく、多くの単独処理浄化槽がFRP製であることから、不要となった単独処理浄化槽の処分に関しても新たな問題を発生させる。また、単独処理浄化槽を掘り起こすことなく、埋め殺す場合には、処分に関する問題が発生しないものの、土地の有効活用ができないとの別の問題を発生させる。
【0004】
本発明は、上記のような課題に鑑みてなされたものであり、既設の単独処理浄化槽を有効利用することで、単独処理浄化槽の処分問題を解決すると共に、新たに合併処理浄化槽を購入するよりも安価に生活雑排水を処理可能な合併処理化装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は、次のものに関する。
(1)単独処理浄化槽に配管接続することにより、排水の合併処理を可能とする合併処理化装置において、その合併処理化装置が、好気処理を行うための生物反応部と、その生物反応部の下流側にて排水の濾過を行うための濾過部とを有し、単独処理浄化槽との配管接続が、単独処理浄化槽の消毒室に流入する直前の排水を上記生物反応部へと流入させる移流管と、上記濾過部を洗浄した排水を単独処理浄化槽の嫌気処理部又は沈殿分離室へと移送する洗浄排水移送管と、上記濾過部の下流側の排水を単独処理浄化槽の消毒室に返送する返送管とによりなされ、浴槽からの排水を上記生物反応部へと流入させる浴槽排水配管が、上記生物反応部又は移流管に設けられ、この浴槽排水配管が流量調整弁を備えている合併処理化装置。
(2)生物反応部が、その上流側に流量調整槽を有し、単独処理浄化槽及び浴槽からの排水が上記流量調整槽を介して生物反応部へと流入する上記(1)に記載される合併処理化装置。
【0006】
【発明の実施の形態】
本発明の合併処理化装置を配管接続する単独処理浄化槽は、少なくとも嫌気処理部又は沈殿分離室と、消毒室とを有するものであれば特に限定されるものではなく、具体的には、従来技術にて説明したように、流入口及び流出口を有し、内部に上流側から沈殿分離室、接触ばっ気室、沈殿室、消毒室を設けたものを好適に用いることができる。
【0007】
本発明に用いる合併処理化装置は、少なくとも好気処理を行う生物反応部と排水の濾過を行う濾過部とを有するものであれば特に限定されるものではない。生物反応部及び濾過部についてより具体的に述べると、一例としては、槽内に担体を充填して担体層を形成し、その担体層の下部及び内部に散気管を設け、担体層の内部に設置した散気管より上側の担体層にて主に好気処理を行い、担体層の内部に設置した散気管より下側の担体層にて主に濾過を行うことができる。また、別の例としては、通水板により区画した上下2段の担体層を形成すると共に各々の担体層の下部に散気管を設置し、水を通水する際に上流側となる担体層を生物反応部となし、下流側の担体層を濾過部とすることができる。
【0008】
生物反応部に用いる担体は、微生物を多く保持可能であることから、網様円筒状、骨格様球状、へちま状、小円筒状、波板状、チューブ状、繊維絡み状等の合成樹脂製の成形体、独立気泡体又は連通気泡体を有した合成樹脂製の成形体、アンスラサイト(無煙炭)、珪砂、セラミック等の無機体を好適に用いることができる。
【0009】
濾過部に用いる担体(濾材)は、生物反応部に用いた担体と同様の担体を好適に使用することができるが、異なるものでもよい。濾過を行う部分の底部に配置した散気管は、通常状態で継続的に空気泡の吐出を行うことがなく、担体が静止状態を保ち濾過の行いやすい環境を維持させるが、継続して濾過を行っていると担体に生物膜が厚く堆積するので、定期的に空気泡を吐出させて担体の攪拌を行い、担体から生物膜の剥離を行う。担体の洗浄により剥離させた生物膜は、単独処理浄化槽の嫌気処理部又は沈殿分離室へと、洗浄排水移送管により移送させることが好ましい。
【0010】
本発明に用いる移流管は、単独処理浄化槽から生物反応部へと排水を移流させるものであり、単独処理浄化槽からの排水は、消毒室に流入する直前の排水とする。具体的には、単独処理浄化槽の接触ばっき室又は沈殿室から排水を抜き取り、生物反応部へと移流させることが好ましい。また、生物反応部の上流側に流量調整槽を設ける場合には、単独処理浄化槽からの排水を一旦流量調整槽へ移流させてから生物反応部へと移流させるようにする。
【0011】
本発明に用いる洗浄排水移送管は、合併処理化装置の濾過部を洗浄した排水を単独処理浄化槽の嫌気処理部又は沈殿分離室へと移送させるものであり、主には、濾過部の担体から剥離させた生物膜を多く含む排水の移送をする。
【0012】
本発明に用いる返送管は、濾過部の下流側の排水を、単独処理浄化槽の消毒室に返送するものであり、返送された排水は、滅菌処理を行われて系外へと放流される。
【0013】
本発明に用いる浴槽排水配管は、浴槽及び浴室からの排水を生物反応部へと流入させるものであり、浴槽及び浴室の排水を直接生物反応部へと流入させても、一旦流量調整槽へ流入させてから生物反応部へと流入させるようにしてもよい。また、浴槽排水配管に通す排水は、少なくとも浴槽及び浴室の排水を含むものであり、浴槽排水以外に、汚れの程度が低い洗濯排水を流してもよい。
【0014】
浴槽排水配管には、流量調整弁を設ける。このようにすることで、一時に大量に発生する浴槽及び浴室の排水を徐々に生物反応部へと流入させ、安定した処理を行えるようになる。また、流量調整弁を設ける代わりに、生物反応部の上流に流量調整槽を設け、合併処理化装置へと流入する排水を一旦流量調整槽に溜め、そこから生物反応部へと流入させるようにすることも、安定した排水処理を行え好ましい。
【0015】
【実施例】
以下図面を用いて、本発明の実施例を説明する。図1は、本発明の実施例を示す、合併処理化装置を単独処理浄化槽に配管接続したものであり、(a)は概略平面図を示し、(b)は概略側断面図を示す。単独処理浄化槽1は、既設のものであり、その内部構造は、上流側から第1流入口11、嫌気処理室22、接触ばっ気室4、沈殿室29、消毒室16、第1流出口12を設けている。そして、上記単独処理浄化槽1を用いて合併処理可能とするには、新たに本発明の合併処理化装置15を設置する。
【0016】
合併処理化装置15は、その内部に生物濾過槽17を有し、その生物濾過槽17は、槽の上下に担体の通過を妨げ排水を通過させる通水部材30、31、32の設置を行い、上記通水部材30、31間及び通水部材31、32間に担体を充填し、上側の担体層を生物反応部18となし、下側の担体層を濾過部19としている。生物反応部18及び濾過部19の下部には、散気部材20、21が設けられている。生物反応部18の下部に設けられた散気部材20は、好気処理を行うために使用されるものであり、常時空気泡の吐出を行っているが、濾過部19の下部に設けられた散気部材21は、生物膜の剥離を行う洗浄の際に使用されるもので、1日1回の空気泡の吐出を1〜30分程度行う。また、濾過部19の下流側には、処理水貯留部34を設けている。
【0017】
単独処理浄化槽1と合併処理化装置15との配管接続は、沈殿室29と第2流入口13とを移流管37により接続することで行われ、上記移流管37は、排水を単独処理浄化槽1から合併処理化装置15へと移流させる以外に、浴槽排水配管26を用いることで、浴槽及び浴室の排水を合併処理化装置15へと移流させる。また、第2流出口と消毒室16とは、返送管38により配管接続され、処理水貯留部34から消毒室16へと排水を返送する。
【0018】
水の流れについて説明すると、家庭から排出される屎尿、台所排水(ディスポーザ排水を含む)、洗面排水及び洗濯排水(以下まとめて排水aと言う)は、第1流入口11から嫌気処理室22へと流入して固液分離及び嫌気処理を行われ、接触ばっ気室4にて栄養基質の酸化除去が行われる。接触ばっ気室4を通過した排水aは、沈殿室29内で固形分の沈殿分離を行われ、第1流出口12を介して移流管37へと流入する。
【0019】
移流管37では、浴槽排水配管26から流入する浴槽及び浴室の排水(以下排水bという)と排水aとが合流して、第2流入口13より合併処理化装置15へと移流する。排水a、bは、生物反応部18にて散気部材20からの空気泡の吐出による好気処理がなされ、その後濾過部19にて生物反応部18からの持込み酸素で好気処理を行いながら、固形物質の除去を行い、処理水貯留部34へと移流する。排水a、bは、処理水貯留部34から返送管38を介して消毒室16へと流入し、滅菌処理を行われた後に第1流出口12から放流される。
【0020】
濾過部19は、継続して濾過を行うと、担体に生物膜が厚く堆積して閉塞するので、定期的に散気部材21から空気泡を吐出させて担体の攪拌を行い、担体から生物膜を剥離させる。剥離された生物膜は、移送ポンプ23を稼働させることで、洗浄排水移送管24より引き抜き、嫌気処理室22へと返送する。
【0021】
図2は、図1に示す浴槽排水配管に流量調整弁を設けた合併処理化装置の概略平面図を示す。排水bは、浴槽及び浴室の排水であるために、数分間に約200〜300lという大量の排水を発生させる。そのため、生物濾過槽17の容量を十分に大きく確保していない場合には、処理の行われない排水をそのまま放流することになりかねない。そのため、生物濾過槽17の容量を十分に確保できない場合には、浴槽排水配管26に流量調整弁27を設けることで、少量づつ排水bを生物濾過槽17へと流入させ、安定した処理を行うようにする。
【0022】
図3は、本発明の合併処理化装置に、流量調整槽を設けた場合の概略側断面図を示す。本実施例では、排水a、bを一旦流量調整槽28に流入させ、そこからポンプ35を用いて生物濾過槽17へと移流させている。上記流量調整槽28を用いる場合には、図2に示すような流量調整弁27を用いずに安定した処理を行うことができる。
【0023】
図4は、合併処理化装置と流量調整槽とを一体化せずに配管接続した合併処理化装置の概略側断面図を示す。このような構成であれば、地中に埋設するのは流量調整槽36だけで済み、合併処理化装置15は地上設置することが可能となる。
【0024】
【発明の効果】
本発明は、既設の単独処理浄化槽を利用することにより合併処理を可能としたので、単独処理浄化槽を処分して新たに合併処理浄化槽を設置するよりも、安価に合併処理を行うことが可能であり、単独処理浄化槽を処分する必要もなくなる。また、浴槽排水配管に流量調整弁を設けた場合には、生物反応部及び濾過部の容量を大きくする必要がなくなり、合併処理化装置全体を小型化することが可能となる。更に、合併処理化装置に流量調整槽を設けた場合には、安定した排水処理を行うことができ、特に合併処理化装置と流量調整槽とを一体化せずに配管接続するのであれば、合併処理化装置を地上設置することで施工費用を低く抑えることが可能となる。
【0025】
本発明は、単独処理浄化槽を通過した排水を単純に合併処理化装置へと流入させ、合併処理を行っているのではなく、単独処理浄化槽の消毒室に流入する直前の排水を合併処理化装置へと流入させ、その後、上記消毒室へと返送するので、合併処理化装置に消毒室を設けることなく、既存の単独処理浄化槽に付設する消毒室を活用することが可能であり、部材点数を低減し且つ資源の有効活用を行える。

BACKGROUND OF THE INVENTION
The present invention relates to a merger processing apparatus.
[0002]
[Prior art]
Conventionally, a single treatment septic tank has been used as a device for purifying manure. FIG. 5 is a schematic cross-sectional view showing a single processing septic tank of a separation contact aeration method. The manure flows from the inlet 2 into the precipitation separation chamber 3, undergoes solid-liquid separation and anaerobic treatment, and is transferred to the contact aeration chamber 4. In the contact aeration chamber 4, the advected water is agitated by the air bubbles diffused from the diffuser tube 7 and comes into contact with the contact material 8, whereby the nutrient substrate is gradually oxidized and removed. Since the biofilm accumulates thickly and closes when the contact material 8 is continuously stirred, the biofilm is peeled off by periodically discharging air bubbles from the backwash tube 9. The water that has passed through the contact aeration chamber 4 is subjected to precipitation separation of solids in the precipitation chamber 5, and then the separated supernatant is transferred to the disinfection chamber 6, sterilized, and then discharged from the outlet 10. Is done.
[0003]
[Problems to be solved by the invention]
However, the single-treatment septic tank has a problem that the type of water to be treated is limited to manure, and it cannot treat household wastewater such as kitchen wastewater, laundry wastewater, bathroom wastewater, and bathtub wastewater. Such problems can be solved by removing the existing single processing septic tank and installing a new merged processing septic tank, but not only the construction cost is high, but many single processing septic tanks are made of FRP. Therefore, a new problem is generated with respect to the disposal of the single processing septic tank that has become unnecessary. In addition, if the single treatment septic tank is buried without being dug up, a problem regarding disposal will not occur, but another problem will occur that the land cannot be used effectively.
[0004]
The present invention has been made in view of the problems as described above. By effectively utilizing the existing single-treatment septic tank, the problem of disposal of the single-treatment septic tank can be solved, and a new merged septic tank can be purchased. Another object of the present invention is to provide a merger treatment apparatus capable of treating domestic wastewater at a low cost.
[0005]
[Means for Solving the Problems]
The present invention relates to the following.
(1) In a merger treatment apparatus that enables wastewater merger processing by connecting a pipe to a single treatment septic tank, the merger treatment apparatus performs aerobic treatment, and a bioreaction part thereof And a filtration part for filtering the waste water on the downstream side, and the pipe connection with the single treatment septic tank allows the waste water just before flowing into the disinfection chamber of the single treatment septic tank to flow into the biological reaction part A pipe, a cleaning drainage transfer pipe for transferring the wastewater after washing the filtration unit to an anaerobic treatment unit or a precipitation separation chamber of the single treatment septic tank, and returning wastewater downstream of the filtration unit to the disinfection chamber of the single treatment septic tank. The bathtub drainage pipe that is made by the return pipe and allows the wastewater from the bathtub to flow into the biological reaction part is provided in the biological reaction part or the advection pipe, and this bathtub drainage pipe is provided with a flow control valve . apparatus.
(2) The biological reaction unit has a flow rate adjustment tank on the upstream side thereof, and the waste water from the single treatment septic tank and the bathtub flows into the biological reaction unit through the flow rate adjustment tank. Merger processing equipment.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The single treatment septic tank for pipe connection of the merger treatment apparatus of the present invention is not particularly limited as long as it has at least an anaerobic treatment section or a sedimentation separation chamber, and a disinfection chamber. As described in the above, an apparatus having an inlet and an outlet and provided with a precipitation separation chamber, a contact aeration chamber, a precipitation chamber, and a disinfection chamber from the upstream side can be suitably used.
[0007]
The merger treatment apparatus used in the present invention is not particularly limited as long as it has at least a biological reaction part that performs aerobic treatment and a filtration part that filters wastewater. More specifically, the biological reaction section and the filtration section are described. As an example, a tank is filled with a carrier to form a carrier layer, and a diffusion tube is provided below and inside the carrier layer. The aerobic treatment is mainly performed in the carrier layer above the installed diffuser tube, and the filtration is mainly performed in the carrier layer below the diffuser tube installed inside the carrier layer. Further, as another example, a carrier layer which is formed upstream and bottom when partitioned by a water flow plate and an aeration pipe is installed below each carrier layer to allow water to flow through. Can be used as a biological reaction part, and a downstream carrier layer can be used as a filtration part.
[0008]
Since the carrier used in the biological reaction part can hold many microorganisms, it is made of synthetic resin such as a net-like cylindrical shape, a skeleton-like spherical shape, a square shape, a small cylindrical shape, a corrugated plate shape, a tube shape, or a fiber-entangled shape. An inorganic body such as a molded body, a molded body made of a synthetic resin having closed cells or open cells, anthracite (anthracite), silica sand, and ceramic can be suitably used.
[0009]
As the carrier (filter medium) used in the filtration part, the same carrier as that used in the biological reaction part can be preferably used, but it may be different. The air diffuser placed at the bottom of the part to be filtered does not continuously discharge air bubbles in the normal state and maintains the environment in which the carrier is stationary and easy to filter. Since the biofilm is deposited thickly on the carrier, the carrier is stirred by periodically discharging air bubbles to peel off the biofilm from the carrier. The biofilm peeled off by washing the carrier is preferably transferred to the anaerobic treatment section or precipitation separation chamber of the single treatment septic tank by a washing drainage transfer pipe.
[0010]
The advection pipe used in the present invention transfers waste water from the single treatment septic tank to the biological reaction section, and the waste water from the single treatment septic tank is drained immediately before flowing into the disinfection chamber. Specifically, it is preferable to drain the waste water from the contact chamber or settling chamber of the single treatment septic tank and transfer it to the biological reaction section. When a flow rate adjustment tank is provided upstream of the biological reaction unit, the waste water from the single treatment septic tank is once transferred to the flow rate adjustment tank and then transferred to the biological reaction unit.
[0011]
The washing drainage transfer pipe used in the present invention is for transferring the wastewater that has washed the filtration part of the combined treatment apparatus to the anaerobic treatment part or precipitation separation chamber of the single treatment septic tank, mainly from the carrier of the filtration part. Transport wastewater containing a lot of exfoliated biofilm.
[0012]
The return pipe used in the present invention returns the waste water on the downstream side of the filtration unit to the sterilization chamber of the single treatment septic tank, and the returned waste water is sterilized and discharged outside the system.
[0013]
The bathtub drainage pipe used in the present invention allows wastewater from the bathtub and bathroom to flow into the biological reaction part, and even if the wastewater from the bathtub and bathroom directly flows into the biological reaction part, it once flows into the flow rate adjustment tank. Then, it may be allowed to flow into the biological reaction part. Moreover, the waste_water | drain passing through bathtub drainage piping contains the waste_water | drain of a bathtub and a bathroom at least, You may flow the washing waste_water | drain with a low grade of dirt other than bathtub drainage.
[0014]
The bathtub drain pipe, Ru provided flow control valve. By doing in this way, the waste_water | drain of the bathtub and bathroom which generate | occur | produce in large quantities at once can be made to flow gradually into a biological reaction part, and a stable process can be performed now now. Also, instead of providing a flow control valve, a flow control tank is provided upstream of the biological reaction section so that the wastewater flowing into the merger treatment apparatus is temporarily stored in the flow control tank and then flows into the biological reaction section from there. It is also preferable to perform stable wastewater treatment.
[0015]

FIG. 2 is a schematic plan view of the merger processing apparatus in which the flow rate adjusting valve is provided in the bathtub drain pipe shown in FIG. Since the drainage b is a drainage of a bathtub and a bathroom, a large amount of drainage of about 200 to 300 l is generated in several minutes. Therefore, if the capacity of the biological filtration tank 17 is not sufficiently large, wastewater that is not treated may be discharged as it is. Therefore, when the capacity of the biological filtration tank 17 cannot be sufficiently secured, the flow rate adjusting valve 27 is provided in the bathtub drainage pipe 26 so that the wastewater b is gradually introduced into the biological filtration tank 17 to perform stable treatment. Like that.

With such a configuration, only the flow rate adjusting tank 36 is embedded in the ground, and the merger processing apparatus 15 can be installed on the ground.
[0024]
【The invention's effect】
Since the present invention enables the merger process by utilizing the existing single treatment septic tank, it is possible to perform the merger process at a lower cost than disposing the single process septic tank and installing a new merged process septic tank. There is no need to dispose of the single treatment septic tank. Moreover, when the flow regulating valve is provided in the bathtub drainage pipe, it is not necessary to increase the capacities of the biological reaction part and the filtration part, and the entire merger processing apparatus can be downsized. Furthermore, when the flow control tank is provided in the merger processing apparatus, stable drainage treatment can be performed, and in particular, if the pipe connection is made without integrating the merger processing apparatus and the flow control tank, Installation cost can be kept low by installing the merger processing equipment on the ground.
[0025]
In the present invention, the waste water that has passed through the single treatment septic tank is simply allowed to flow into the merger treatment apparatus, and the merger treatment is not performed. And then returned to the sterilization chamber, it is possible to utilize the sterilization chamber attached to the existing single processing septic tank without providing a sterilization chamber in the merger processing equipment, Reduction and effective use of resources.
