Description

濾過処理装置及び濾過処理装置の洗浄方法Filtration treatment apparatus and cleaning method for filtration treatment apparatus
 本発明は、濾過膜を具備した濾過処理装置及び当該濾過処理装置の洗浄方法に関し、特に、濾過膜を具備し、オゾン含有液を用いて当該濾過膜の洗浄が可能とされた浄水装置および当該浄水装置のオゾン含有液を用いた洗浄方法に関する。 The present invention relates to a filtration apparatus equipped with a filtration membrane and a cleaning method for the filtration treatment apparatus, and in particular, a water purifier equipped with a filtration membrane and capable of washing the filtration membrane using an ozone-containing liquid, and the The present invention relates to a cleaning method using an ozone-containing liquid in a water purifier.
 従来、上下水道用、飲料用、工業用、農業用として利用される浄水方法、または排液の処理に適用される浄水方法として、濾過膜によって被処理用水に含まれる固形物などの微小物体を除去して浄水する浄水技術が利用されている。この方式による浄水方法では、長時間にわたっての浄水処理の継続に伴い、濾過膜の表面に無機物などの固形物や有機物などの汚濁物質が付着することで目詰まりが生じ、濾過膜の濾過特性に低下が生じることが知られている。 Conventionally, as a water purification method used for water and sewage, beverage use, industrial use, agricultural use, or a water purification method applied to the treatment of drainage, a fine object such as solid matter contained in water to be treated by a filtration membrane is used. Water purification technology that removes and purifies water is used. With this type of water purification method, as water purification treatment continues for a long time, clogging occurs due to the adherence of solid substances such as inorganic substances and pollutants such as organic substances to the surface of the filtration film, which affects the filtration characteristics of the filtration film. It is known that a decrease occurs.
 そこで、この低下した濾過特性を回復させるために、オゾン含有液などの洗浄液によって濾過膜を洗浄する技術が知られている。例えば、特開2003-251160号公報(特許文献1)には、オゾン水生成器と、濾過膜と、洗浄水供給ラインと、バイパスラインとを備えた水処理装置が開示されており、当該水処理装置においては、オゾン水生成器で生成したオゾン水により濾過膜を洗浄する技術が開示されている。 Therefore, a technique for cleaning the filtration membrane with a cleaning liquid such as an ozone-containing liquid is known in order to recover the reduced filtration characteristics. For example, Japanese Patent Application Laid-Open No. 2003-251160 (Patent Document 1) discloses a water treatment apparatus including an ozone water generator, a filtration membrane, a washing water supply line, and a bypass line. In the processing apparatus, a technique for cleaning a filtration membrane with ozone water generated by an ozone water generator is disclosed.
特開2003-251160号公報JP 2003-251160 A
 しかしながら、上記公報に開示の水処理装置は、洗浄に利用したオゾン水に特別な処理を施さず、オゾン水をそのまま水処理装置の外部へ排水させている。このため、オゾン水に含まれた高濃度のオゾンガスが大気に放出される恐れがあった。オゾンガスが低濃度の場合には、人体に影響を与えないが、濃度の高いオゾンガスを直接吸い込んだ場合には、人体に悪影響を与えることが一般的に知られている。このため、上記公報に開示の水処理装置は、安全性の面で利用が困難な状況にあると言える。 However, the water treatment device disclosed in the above publication does not perform any special treatment on the ozone water used for cleaning, and drains the ozone water directly to the outside of the water treatment device. For this reason, there is a risk that high-concentration ozone gas contained in ozone water may be released to the atmosphere. It is generally known that when the ozone gas has a low concentration, the human body is not affected, but when the ozone gas having a high concentration is directly inhaled, the human body is adversely affected.

 濾過部101は、濾過膜により構成され、液体または気体に固形物が混ざった混合物を細かい穴が設けられた濾過膜に一方向から通すことで、穴よりも大きな固形物の粒子を液体または気体から分離する。ここで、濾過膜は、例えば中空糸フィルタや活性炭フィルタ、イオン交換樹脂フィルタなど、一般的な濾過膜が利用できる。 The filtration unit 101 is configured by a filtration membrane. By passing a mixture in which a solid substance is mixed in a liquid or gas from one direction through a filtration membrane having fine holes, solid particles larger than the hole can be passed through the liquid or gas. Separate from. Here, as the filtration membrane, for example, a general filtration membrane such as a hollow fiber filter, an activated carbon filter, or an ion exchange resin filter can be used.
 また、濾過部101は、配管aと配管bとに接続され、濾過処理時において、配管aから導入された水などの液体を濾過し、濾過した後の液体を配管bに導出する。一方、濾過部101の洗浄時には、濾過処理時の流動方向とは逆方向に配管bから濾過部101に対してオゾン含有液が導入され、洗浄に用いられた後のオゾン含有液が濾過部101から配管aに導出される。これにより、オゾン含有液を用いた濾過部101の逆洗浄が行なわれる。ここで、逆洗浄とは、濾過処理方向とは逆方向に液体を流動させることで濾過膜を洗浄する洗浄方法であり、濾過処理方向では除去できない濾過膜に付着した無機物などの固形物や有機物などの汚濁物質による濾過膜の目詰まりを解消する洗浄方法である。 Further, the filtration unit 101 is connected to the pipe a and the pipe b, filters the liquid such as water introduced from the pipe a during the filtration process, and guides the filtered liquid to the pipe b.

This is a cleaning method that eliminates clogging of filtration membranes caused by contaminants such as
 次に、本実施形態に係る係る濾過処理装置100に具備される濾過部101の一構成例について、図2を用いて説明する。図2は、図1に示す濾過部の一構成例を示す概略図である。 Next, a configuration example of the filtration unit 101 provided in the filtration apparatus 100 according to the present embodiment will be described with reference to FIG.

The solution to be treated that has been subjected to the filtration treatment is led out from the pipe b. Here, for example, a hollow fiber filter is used as the filtration membrane 22, and in this case, the solution to be treated that is in contact with the surface of the hollow fiber filter is sucked up by a capillary phenomenon or a pressure difference between the inside and outside of the hollow fiber, and the hollow fiber filter is used.

The liquid stored in the liquid supply source 109 by the pressure feeding unit 111 is supplied to the ozone-containing liquid generation unit 112, and thereby the ozone-containing liquid generation unit 112 generates an ozone-containing liquid.
 オゾン含有液生成部112は、配管bと連通して接続された配管dと、液体供給源109に連通して接続された配管gとに接続され、液体供給源109から供給される液体をもとにオゾン含有液を生成し、生成したオゾン含有液を配管dを介して配管bへ供給する。また、配管dには、開閉弁V2が設けられ、これによりオゾン含有液の供給量を制御することが可能である。なお、配管gは、ポンプなどから形成される圧送部111と接続されており、圧送部111は、配管gを介して液体供給源109の液体をオゾン含有液生成部112に圧送する。 The ozone-containing liquid generation unit 112 is connected to a pipe d connected in communication with the pipe b and a pipe g connected in communication with the liquid supply source 109, and has a liquid supplied from the liquid supply source 109. And an ozone-containing liquid is generated, and the generated ozone-containing liquid is supplied to the pipe b through the pipe d. In addition, the pipe d is provided with an on-off valve V2, which makes it possible to control the supply amount of the ozone-containing liquid. Note that the pipe g is connected to a pumping unit 111 formed from a pump or the like, and the pumping unit 111 pumps the liquid of the liquid supply source 109 to the ozone-containing liquid generation unit 112 via the pipe g.
 なお、図1のオゾン含有液生成部112は、液体供給源109と圧送部111とを含むように構成した場合のものであるが、液体供給源109と圧送部111とを濾過処理装置100の外部に設ける構成としてもよい。例えば、オゾン含有液生成器102としては、オゾン含有液生成部112に、開閉弁を備えた水道配管などを直接、接続させた構成としてもよい。 1 is configured to include the liquid supply source 109 and the pressure feeding unit 111, the liquid supply source 109 and the pressure feeding unit 111 are connected to the filtration processing apparatus 100. It is good also as a structure provided outside. For example, the ozone-containing liquid generator 102 may be configured such that a water pipe or the like provided with an on-off valve is directly connected to the ozone-containing liquid generating unit 112.
 次に、本実施形態に係る濾過処理装置100に具備されるオゾン含有液生成部112の一構成例について、図3を用いて詳細に説明する。図3は、図1に示すオゾン含有液生成部の一構成例を示す概略図である。 Next, a configuration example of the ozone-containing liquid generation unit 112 provided in the filtration apparatus 100 according to the present embodiment will be described in detail with reference to FIG. FIG. 3 is a schematic diagram illustrating a configuration example of the ozone-containing liquid generation unit illustrated in FIG. 1.
 図3のオゾン含有液生成部112aは、オゾン発生器201により発生させたオゾンガスと水などの液体とを気液混合器202にて混合させ、気液混合体としてのオゾン含有液を生成するものである。 The ozone-containing liquid generation unit 112a in FIG. 3 generates ozone-containing liquid as a gas-liquid mixture by mixing the ozone gas generated by the ozone generator 201 and a liquid such as water in the gas-liquid mixer 202. It is.
 ここで、気液混合体は、液体に気体が溶解した液体、または、液体に気体が気泡として含まれた液体の状態のものを意味し、液体にオゾンガスが溶け込んだオゾン溶液、または、液体にオゾンガスが気泡として混合されるオゾンバブル液が含まれる。また、混合される液体には、水や農耕用の溶媒として利用される栽培養液、医療用の溶媒として利用される溶液など、オゾンガスを混合させる溶液が含まれる。 Here, the gas-liquid mixture means a liquid in which a gas is dissolved in a liquid or a liquid in which a gas is contained as bubbles in a liquid, and an ozone solution or a liquid in which ozone gas is dissolved in a liquid. An ozone bubble liquid in which ozone gas is mixed as bubbles is included. Further, the liquid to be mixed includes a solution in which ozone gas is mixed, such as water or a cultivation nutrient solution used as an agricultural solvent or a solution used as a medical solvent.
 オゾン発生器201には、配管eを介して気体導入口203から空気や酸素などの気体が導入される。オゾン発生器201は、オゾン発生器201内に設けられたオゾン発生素子にてオゾンガスを発生させ、発生させたオゾンガスを気体導出口204から配管fへ導出する。ここで、配管eは、一端がオゾン発生器201の気体導入口203に接続され、もう一端が大気または図示しない酸素や空気などが貯蔵されたボンベなどに接続されている。 In the ozone generator 201, a gas such as air or oxygen is introduced from the gas inlet 203 through the pipe e. The ozone generator 201 generates ozone gas by an ozone generation element provided in the ozone generator 201 and guides the generated ozone gas from the gas outlet port 204 to the pipe f. Here, one end of the pipe e is connected to the gas inlet 203 of the ozone generator 201, and the other end is connected to the atmosphere or a cylinder storing oxygen or air (not shown).
 気液混合器202には、配管fを介して気体導入口205からオゾンガスが導入されるとともに、配管gを介して液体導入口206から水などの液体が圧送されて導入される。気液混合器202においては、導入されたオゾンガスと水などの液体とが混合されることでオゾン含有液が生成され、生成されたオゾン含有液が導出口207から配管dに供給される。 In the gas-liquid mixer 202, ozone gas is introduced from the gas inlet 205 via the pipe f, and liquid such as water is pumped and introduced from the liquid inlet 206 via the pipe g. In the gas-liquid mixer 202, an ozone-containing liquid is generated by mixing the introduced ozone gas and a liquid such as water, and the generated ozone-containing liquid is supplied from the outlet 207 to the pipe d.
 次に、本実施形態に係る濾過処理装置100に具備されるオゾン含有液生成部112の他の構成例について、図4を用いて詳細に説明する。図4は、図1に示すオゾン含有液生成部の他の構成例を示す概略図である。当該他の構成例に係るオゾン含有液生成部112bは、気体循環型のオゾン含有液生成部である。なお、図3に示す構成部材と同一の構成部材には、図中同一の符号を付し、その詳細な説明は繰り返さない。 Next, another configuration example of the ozone-containing liquid generation unit 112 provided in the filtration apparatus 100 according to the present embodiment will be described in detail with reference to FIG. FIG. 4 is a schematic diagram illustrating another configuration example of the ozone-containing liquid generation unit illustrated in FIG. 1. The ozone-containing liquid generator 112b according to the other configuration example is a gas circulation type ozone-containing liquid generator. In addition, the same code | symbol is attached | subjected in the figure to the structural member same as the structural member shown in FIG. 3, and the detailed description is not repeated.
 図4のオゾン含有液生成部112bは、気体を循環する循環経路Aを有し、オゾンガスを発生させるオゾン発生器201と、液体とオゾンガスとを混合する気液混合器202と、気液混合体を気体と液体とに分離する第2の気液分離器208とが循環経路Aに設けられた構成を有している。ここで、循環経路Aは、気体または液体が循環するオゾン含有液生成部112b内に設けられた経路であり、配管i、配管fおよび配管hにより形成されている。 4 has a circulation path A for circulating gas, an ozone generator 201 for generating ozone gas, a gas-liquid mixer 202 for mixing liquid and ozone gas, and a gas-liquid mixture. The second gas-liquid separator 208 that separates the gas into liquid and gas is provided in the circulation path A. Here, the circulation path A is a path provided in the ozone-containing liquid generation unit 112b through which gas or liquid circulates, and is formed by the pipe i, the pipe f, and the pipe h.
 オゾン含有液生成部112b内の気体は、循環経路Aを介してオゾン発生器201に導入され、これによってオゾン発生器201においてオゾンガスが発生させられる。発生させられたオゾンガスは、配管fを介して気液混合器202の気体導入口205から気液混合器202内に導入され、液体導入口206から配管gを介して導入された水などの液体と混合され、これにより気液混合器202においてオゾン含有液が生成される。生成されたオゾン含有液は、導出口207から配管hへ導出される。 The gas in the ozone-containing liquid generation unit 112b is introduced into the ozone generator 201 via the circulation path A, and thereby ozone gas is generated in the ozone generator 201. The generated ozone gas is introduced into the gas-liquid mixer 202 from the gas inlet 205 of the gas-liquid mixer 202 through the pipe f, and is a liquid such as water introduced from the liquid inlet 206 through the pipe g. As a result, an ozone-containing liquid is generated in the gas-liquid mixer 202. The generated ozone-containing liquid is led out from the outlet 207 to the pipe h.
 配管hへ導出されたオゾン含有液は、第2の気液分離器208の導入口209から第2の気液分離器208内に導入され、第2の気液分離器208において液体と気体とに分離される。第2の気液分離器208において分離された後の液体は、液体導出口210から導出され、第2の気液分離器208において分離された後の気体は、気体導出口211から導出される。 The ozone-containing liquid led out to the pipe h is introduced into the second gas-liquid separator 208 from the introduction port 209 of the second gas-liquid separator 208, and the second gas-liquid separator 208 uses the liquid and gas. Separated. The liquid after being separated in the second gas-liquid separator 208 is led out from the liquid outlet 210, and the gas after being separated in the second gas-liquid separator 208 is led out from the gas outlet 211. .
 ここで、オゾン含有液には、液体にオゾンガスが溶け込んだオゾン溶液や液体にオゾンガスが気泡として混合されるオゾンバブル液が含まれるが、気体と液体とに分離するとは、このオゾン含有液を第2の気液分離器208にてオゾンガスや空気などを含む気体とオゾン溶液を含む液体とに分離することを意味する。 Here, the ozone-containing liquid includes an ozone solution in which ozone gas is dissolved in the liquid and an ozone bubble liquid in which the ozone gas is mixed as bubbles in the liquid. The second gas-liquid separator 208 means that the gas is separated into a gas containing ozone gas or air and a liquid containing an ozone solution.
 液体であるオゾン溶液は、液体導出口210から配管dに導出される。一方、オゾンガスや酸素などを含む気体は、気体導出口211から導出され、配管iを介して再びオゾン発生器201に導入される。このため、オゾン発生器201は、循環するオゾンガスを含む気体をもとにオゾンガスを発生させることになり、より高濃度のオゾンガスを発生させることができ、結果として高濃度のオゾン含有液を生成することが可能となる。なお、配管iには、オゾン含有液生成部112bの外部から気体を導入する気体導入部212が設けられていてもよい。 The liquid ozone solution is led out from the liquid outlet 210 to the pipe d. On the other hand, a gas containing ozone gas or oxygen is led out from the gas outlet 211 and is again introduced into the ozone generator 201 through the pipe i. For this reason, the ozone generator 201 will generate ozone gas based on the gas containing the circulating ozone gas, and can generate higher concentration ozone gas, resulting in the generation of high concentration ozone-containing liquid. It becomes possible. In addition, the gas introduction part 212 which introduces gas from the outside of the ozone containing liquid production | generation part 112b may be provided in the piping i.
 気体循環型のオゾン含有液生成部112bは、オゾン含有液生成部112b内に閉じ込められた気体を材料にオゾンガスを生成し、これを液体に溶解させた後に外部へ導出させるか、あるいは気体を気泡として含むオゾン含有液としてこれを外部へ導出させるものであるため、長時間にわたってオゾン含有液生成部112bの動作を継続させた場合には、オゾン含有液生成部112b内の気体が不足することになる。このため、不足した気体をオゾン含有液生成部112b内に導入させるために、上述した気体導入部212を設けることが好ましい。 The gas circulation type ozone-containing liquid generation unit 112b generates ozone gas using the gas confined in the ozone-containing liquid generation unit 112b as a material and dissolves the gas in the liquid, and then discharges the gas to the outside. As the ozone-containing liquid contained in the ozone-containing liquid is led out to the outside, the gas in the ozone-containing liquid generating part 112b is insufficient when the operation of the ozone-containing liquid generating part 112b is continued for a long time. Become. For this reason, in order to introduce the insufficient gas into the ozone-containing liquid generation unit 112b, it is preferable to provide the gas introduction unit 212 described above.
 気体導入部212は、配管jに開閉弁V5が設けられた構成を有しており、配管jは、一方が一部開口された配管iと連通して接続され、もう一方が大気または酸素や空気などが貯蔵されたボンベなどと接続される。 The gas introduction part 212 has a configuration in which an opening / closing valve V5 is provided in the pipe j. One of the pipes j is connected to the pipe i that is partially opened, and the other is connected to the atmosphere or oxygen. Connected to a cylinder that stores air.
 このため、開閉弁V5を開くことで、空気や酸素をオゾン含有液生成部112b内に導入することができる。なお、気体導入部212は、開口された配管iに配管jを介することなく、直接、開閉弁V5が設けられた構成としてもよく、オゾン含有液生成部112bの外部から内部への気体の導入を制御できる構成であれば、他の構成のものであっても構わない。 For this reason, air and oxygen can be introduced into the ozone-containing liquid generating unit 112b by opening the on-off valve V5. In addition, the gas introduction part 212 is good also as a structure by which the on-off valve V5 was provided directly without connecting the pipe i to the open pipe i, and introduce | transduces the gas from the exterior to the inside of the ozone containing liquid production | generation part 112b Any other configuration may be used as long as the configuration can be controlled.
 図1を参照して、液体供給源108は、被処理溶液である水などの液体が貯液された貯液槽としての役割を担うものであり、ポンプなどから形成される圧送部110が設けられた配管aと接続されている。これにより、配管aには、液体供給源108から水などの液体が供給される。 Referring to FIG. 1, a liquid supply source 108 plays a role as a liquid storage tank in which a liquid such as water as a solution to be processed is stored, and is provided with a pumping unit 110 formed from a pump or the like. Connected to the pipe a. Thereby, a liquid such as water is supplied from the liquid supply source 108 to the pipe a.
 なお、図1の濾過処理装置100は、液体供給源108と圧送部110とを含むように構成したものであるが、液体供給源108と圧送部110とを濾過処理装置100の外部に設けた構成としてもよい。例えば、濾過処理装置100としては、配管aと開閉弁とを備えた水道配管などを直接、濾過部101に接続させた構成としてもよい。 1 is configured to include a liquid supply source 108 and a pressure feeding unit 110, but the liquid supply source 108 and the pressure feeding unit 110 are provided outside the filtration processing device 100. It is good also as a structure. For example, the filtration apparatus 100 may have a configuration in which a water pipe having a pipe a and an on-off valve is directly connected to the filtration unit 101.
 図1に示す第1の気液分離器103としては、導入された気液混合体を気体と液体とに分離する機能を有する一般的な気液分離器が利用できる。例えば、第1の気液分離器103は、液体を貯液する円筒状の貯液槽の形状のものや、配管内に気液分離器が形成された構造のものなどとして形成される。第1の気液分離器103は、配管aに連通した配管cに接続するように設けられており、これにより第1の気液分離器103には、洗浄に用いられた後のオゾン含有液が導入される。第1の気液分離器103に導入されたオゾン含有液は、第1の気液分離器103において液体と気体とに分離され、オゾンガスを含む気体は、気体導出口105から濾過処理装置100の外に導出される。ここで、気体導出口105から濾過処理装置100の外へ通じる経路にオゾンフィルタ106を配置することにより、当該オゾンフィルタ106を介してオゾンガスを含む気体が導出されるように構成してもよい。 As the first gas-liquid separator 103 shown in FIG. 1, a general gas-liquid separator having a function of separating the introduced gas-liquid mixture into gas and liquid can be used.

Here, the ozone filter 106 may be disposed in a path that leads from the gas outlet 105 to the outside of the filtration apparatus 100, so that a gas containing ozone gas may be derived through the ozone filter 106.
 一般的に、オゾンフィルタ106は、格子状に構成した紙やアルミニウムにオゾン分解触媒を付着させたものなどから構成され、オゾンフィルタ106を通るオゾンガスを分解する。そのため、オゾンフィルタ106を設けることにより、気体導出口105から気体を安全に放出することができる。 Generally, the ozone filter 106 is composed of paper or aluminum having an ozone decomposing catalyst attached in a lattice shape, and decomposes ozone gas passing through the ozone filter 106. Therefore, by providing the ozone filter 106, the gas can be safely discharged from the gas outlet 105.
 一方、気液分離された後のオゾン溶液は、第1の気液分離器103に貯液されるか、または液体導出口107から濾過処理装置100の外部へ導出される。 On the other hand, the ozone solution after the gas-liquid separation is stored in the first gas-liquid separator 103 or led out of the filtration apparatus 100 from the liquid outlet 107.
 なお、配管cには、開閉弁V4が設けられ、これにより第1の気液分離器103に導入される液体の流量を制御することが可能である。また、配管dには、開閉弁V2が設けられ、これにより濾過部101に供給されるオゾン含有液の供給量を制御することが可能である。 Note that the pipe c is provided with an on-off valve V4, whereby the flow rate of the liquid introduced into the first gas-liquid separator 103 can be controlled. In addition, the pipe d is provided with an on-off valve V2, whereby the supply amount of the ozone-containing liquid supplied to the filtration unit 101 can be controlled.
 また、配管aには、液体供給源108と、配管cが接続された部分である接続部C1との間に開閉弁V1が設けられ、これにより濾過処理装置100に導入する被処理溶液の導入量を制御することが可能である。また、配管bには、配管dが接続された部分である接続部C2と、外部口104との間に開閉弁V3が設けられ、これにより外部口104から導出する液体の導出量を制御することが可能である。このため、開閉弁V1~V4を用いることにより、濾過処理時と洗浄時との切り替えを行なうことが可能となる。 In addition, the pipe a is provided with an on-off valve V1 between the liquid supply source 108 and a connection portion C1 that is a portion to which the pipe c is connected, thereby introducing the solution to be treated introduced into the filtration apparatus 100. It is possible to control the amount. In addition, the pipe b is provided with an on-off valve V3 between the connection portion C2 that is a portion to which the pipe d is connected and the external port 104, thereby controlling the amount of liquid discharged from the external port 104. It is possible. Therefore, by using the on-off valves V1 to V4, it is possible to switch between filtration processing and cleaning.
 なお、上記においては、配管cの経路と、配管aの接続部C1から液体供給源108までの経路とを、開閉弁V1と開閉弁V4とにより切り換える構成とした場合を例示したが、接続部C1に三方弁を設けることによりこれを代用することが可能である。また、上記においては、配管dの経路と、配管bの接続部C2から外部口104までの経路との切り替えを、開閉弁V2と開閉弁V3とにより切り替える構成とした場合を例示したが、同様に、接続部C2に三方弁を設けることによりこれを代用することが可能である。 In the above description, the case where the path of the pipe c and the path from the connection part C1 of the pipe a to the liquid supply source 108 are switched by the on-off valve V1 and the on-off valve V4 is illustrated.

 次に、本実施形態に係る濾過処理装置100の動作について、図1から図4を用いて説明する。
<Description of operation>
Next, operation | movement of the filtration processing apparatus 100 which concerns on this embodiment is demonstrated using FIGS. 1-4.
 濾過処理装置100は、濾過部101による被処理溶液の濾過処理の機能と、濾過部101の洗浄処理の機能とを備えている。 The filtration device 100 has a function of filtering the solution to be treated by the filtration unit 101 and a function of cleaning the filtration unit 101.
 濾過処理とは、濾過部101により被処理溶液を濾過する動作である。濾過処理時には、開閉弁V1を開状態にし、開閉弁をV2を閉状態にし、開閉弁V3を開状態にし、開閉弁をV4を閉状態にして、液体供給源108から水などの被処理溶液を濾過部101に供給する。 The filtration process is an operation of filtering the solution to be treated by the filtration unit 101. At the time of filtration, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is opened, the on-off valve V4 is closed, and a solution to be treated such as water from the liquid supply source 108. Is supplied to the filtration unit 101.
 濾過部101には、液体供給源108から配管aを介して水などの被処理溶液が供給され、濾過部101において濾過処理が行なわれた後に、濾過処理後の被処理溶液が濾過部101から配管bへ導出される。その後、濾過処理がなされた後の被処理溶液は、配管bに設けられた外部口104を通じて、濾過処理装置100の外部へ導出される。 A solution to be treated such as water is supplied from the liquid supply source 108 to the filtration unit 101 via the pipe a. After the filtration process is performed in the filtration unit 101, the solution to be treated after the filtration process is supplied from the filtration unit 101. It is led out to the pipe b. Thereafter, the solution to be treated after the filtration process is led out of the filtration apparatus 100 through the external port 104 provided in the pipe b.
 このため、配管bにより、濾過処理を行なった後の被処理溶液が流動する濾過経路が形成されることになる。ここで、濾過経路とは、濾過部101により濾過処理がなされた後の被処理溶液を濾過処理装置100の外部へ導出する経路を意味する。 For this reason, the piping b forms a filtration path through which the solution to be treated after the filtration treatment flows. Here, the filtration path means a path for leading the solution to be processed after the filtration process by the filtration unit 101 to the outside of the filtration apparatus 100.
 洗浄処理とは、オゾン含有液生成器102にてオゾン含有液を生成し、生成したオゾン含有液を用いて濾過部101または配管を洗浄する動作である。洗浄処理時には、開閉弁V1を閉状態にし、開閉弁V2を開状態にし、開閉弁V3を閉状態にし、開閉弁V4を開状態にして、オゾン含有液生成部112からオゾン含有液を濾過部101に導入し、その洗浄を行なう。 The cleaning treatment is an operation of generating an ozone-containing liquid in the ozone-containing liquid generator 102 and cleaning the filter unit 101 or the piping using the generated ozone-containing liquid. During the cleaning process, the on-off valve V1 is closed, the on-off valve V2 is opened, the on-off valve V3 is closed, the on-off valve V4 is opened, and the ozone-containing liquid generation unit 112 filters the ozone-containing liquid. Introduced into 101, the cleaning is performed.
 オゾン含有液生成部112で生成したオゾン含有液は、配管dを介して配管bに導入される。その後、オゾン含有液は、配管bを介して濾過部101に導入され、濾過部101を洗浄する。洗浄に用いられた後のオゾン含有液は、廃オゾン含有液として配管aおよび配管cをたどり、第1の気液分離器103に導入される。その後、廃オゾン含有液は、第1の気液分離器103において気体と液体とに分離され、オゾンガスを含む気体は、気体導出口105から導出される。このとき、気体導出口105から導出されるオゾンガスは、オゾンフィルタ106によって分解処理がなされた後に外部に導出される。一方、廃オゾン含有液は、液体導出口107から導出される。 The ozone-containing liquid generated by the ozone-containing liquid generating unit 112 is introduced into the pipe b through the pipe d. Thereafter, the ozone-containing liquid is introduced into the filtration unit 101 via the pipe b, and the filtration unit 101 is washed. The ozone-containing liquid after being used for cleaning follows the pipe a and the pipe c as a waste ozone-containing liquid, and is introduced into the first gas-liquid separator 103. Thereafter, the waste ozone-containing liquid is separated into gas and liquid in the first gas-liquid separator 103, and the gas containing ozone gas is led out from the gas outlet 105. At this time, the ozone gas led out from the gas lead-out port 105 is led out after being decomposed by the ozone filter 106. On the other hand, the waste ozone-containing liquid is led out from the liquid outlet 107.
 このため、配管dと配管bとの接続部C2から濾過部101に通じる経路により、洗浄液であるオゾン含有液が流動する洗浄経路が形成されることになる。また、配管aの濾過部101から接続部C1に通じる経路と配管cとにより、洗浄に利用した廃オゾン含有液が排液される排液経路が形成されることになる。ここで、洗浄経路とは、洗浄液を濾過部101に流動させる経路を意味し、排液経路とは、濾過部101の洗浄に利用した廃オゾン含有液が濾過処理装置100の外部に排液される経路を意味する。 Therefore, a cleaning path through which the ozone-containing liquid that is the cleaning liquid flows is formed by a path that leads from the connection portion C2 between the piping d and the piping b to the filtration portion 101. Further, a drainage path through which the waste ozone-containing liquid used for cleaning is drained is formed by the path leading from the filtration part 101 of the pipe a to the connection part C1 and the pipe c. Here, the cleaning path means a path for allowing the cleaning liquid to flow to the filtration unit 101, and the drainage path means that the waste ozone-containing liquid used for cleaning the filtering unit 101 is drained to the outside of the filtration processing apparatus 100. Means a route.

<Description of operation>
Next, operation | movement of the filtration processing apparatus 200 which concerns on this embodiment is demonstrated using FIGS. 2-5.
 濾過処理装置200は、濾過部101による被処理溶液の濾過処理の機能と、オゾン含有液生成器102の液体供給源109への液体供給処理の機能と、濾過部101の洗浄処理の機能とを備えている。 The filtration apparatus 200 has a function of filtering the solution to be treated by the filtering unit 101, a function of supplying liquid to the liquid supply source 109 of the ozone-containing liquid generator 102, and a function of cleaning processing of the filtering unit 101. I have.
 濾過処理とは、濾過部101により被処理溶液を濾過する動作である。濾過処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を開状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にして、液体供給源108から水などの被処理溶液を濾過部101に供給する。 The filtration process is an operation of filtering the solution to be treated by the filtration unit 101. During the filtration process, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is opened, the on-off valve V4 is closed, and the on-off valve V6 is opened. A solution to be treated such as water is supplied to the filtration unit 101.
 濾過部101には、液体供給源108から配管aを介して水などの被処理溶液が供給され、濾過部101において濾過処理が行なわれた後に、濾過処理後の被処理溶液が濾過部101から配管bへ導出される。その後、濾過処理がなされた後の被処理溶液は、配管bに設けられた外部口104を通じて、濾過処理装置200の外部へ導出される。このため、配管bにより、濾過処理を行なった後の被処理溶液が流動する濾過経路が形成されることになる。ここで、濾過経路とは、濾過部101により濾過処理がなされた後の被処理溶液を濾過処理装置200の外部へ導出する経路を意味する。 A solution to be treated such as water is supplied from the liquid supply source 108 to the filtration unit 101 via the pipe a. After the filtration process is performed in the filtration unit 101, the solution to be treated after the filtration process is supplied from the filtration unit 101. It is led out to the pipe b. Thereafter, the solution to be treated after the filtration process is led out of the filtration apparatus 200 through the external port 104 provided in the pipe b. For this reason, the filtration path through which the solution to be treated after the filtration process flows is formed by the pipe b. Here, the filtration route means a route for leading the solution to be treated after the filtration processing by the filtration unit 101 to the outside of the filtration processing apparatus 200.
 オゾン含有液生成器102の液体供給源109への液体供給処理とは、濾過部101において濾過処理した水などの被処理溶液をオゾン含有液生成器102の液体供給源109に供給する動作である。これにより、オゾン含有液を生成するために必要な液体を液体供給源109に貯液することが可能になる。 The liquid supply process to the liquid supply source 109 of the ozone-containing liquid generator 102 is an operation of supplying a solution to be processed such as water filtered by the filtration unit 101 to the liquid supply source 109 of the ozone-containing liquid generator 102. . Thereby, it is possible to store the liquid necessary for generating the ozone-containing liquid in the liquid supply source 109.
 液体供給源109への液体供給処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を閉状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にして、液体供給源108から被処理溶液を濾過部101に導入する。 At the time of liquid supply processing to the liquid supply source 109, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is closed, the on-off valve V4 is closed, and the on-off valve V6 is opened. Then, the solution to be treated is introduced into the filtration unit 101 from the liquid supply source 108.
 導入された被処理溶液は、配管aを介して濾過部101に導入され、濾過後に濾過処理済みの被処理溶液が配管bに導出される。その後、濾過処理済みの被処理溶液は、配管bおよび配管kをたどり、液体供給源109に導入される。このため、配管bと配管kとにより、液体供給源109に液体を供給する液体供給経路が形成されることになる。液体供給経路とは、濾過処理がなされた後の液体をオゾン含有液生成器102の液体供給源に109に供給する経路を意味する。 The introduced solution to be treated is introduced into the filtration unit 101 via the pipe a, and after filtration, the solution to be treated after filtration is led to the pipe b. Thereafter, the solution to be treated after filtration is introduced into the liquid supply source 109 along the pipe b and the pipe k. For this reason, the liquid supply path for supplying the liquid to the liquid supply source 109 is formed by the pipe b and the pipe k. The liquid supply path means a path for supplying the liquid after the filtering process to the liquid supply source of the ozone-containing liquid generator 102 to 109.
 洗浄処理とは、オゾン含有液生成器102にてオゾン含有液を生成し、生成したオゾン含有液を用いて濾過部101または配管を洗浄する動作である。洗浄処理時には、開閉弁V1を閉状態にし、開閉弁V2を開状態にし、開閉弁V3を閉状態にし、開閉弁V4を開状態にし、開閉弁V6を閉状態にして、オゾン含有液生成部112からオゾン含有液を濾過部101に導入し、その洗浄を行なう。 The cleaning treatment is an operation of generating an ozone-containing liquid in the ozone-containing liquid generator 102 and cleaning the filter unit 101 or the piping using the generated ozone-containing liquid. During the cleaning process, the on-off valve V1 is closed, the on-off valve V2 is opened, the on-off valve V3 is closed, the on-off valve V4 is opened, the on-off valve V6 is closed, and the ozone-containing liquid generating unit The ozone-containing liquid is introduced into the filtration unit 101 from 112 and cleaned.
 オゾン含有液生成部112で生成したオゾン含有液は、配管dを介して配管bに導入される。その後、オゾン含有液は、配管bを介して濾過部101に導入され、濾過部101を洗浄する。洗浄に用いられた後のオゾン含有液は、廃オゾン含有液として配管aおよび配管cをたどり、第1の気液分離器103に導入される。その後、廃オゾン含有液は、第1の気液分離器103において気体と液体とに分離され、オゾンガスを含む気体は、気体導出口105から導出される。このとき、気体導出口105から導出されるオゾンガスは、オゾンフィルタ106によって分解処理がなされた後に外部に導出される。一方、廃オゾン含有液は、液体導出口107から導出される。 The ozone-containing liquid generated by the ozone-containing liquid generating unit 112 is introduced into the pipe b through the pipe d. Thereafter, the ozone-containing liquid is introduced into the filtration unit 101 via the pipe b, and the filtration unit 101 is washed. The ozone-containing liquid after being used for cleaning follows the pipe a and the pipe c as a waste ozone-containing liquid, and is introduced into the first gas-liquid separator 103. Thereafter, the waste ozone-containing liquid is separated into gas and liquid in the first gas-liquid separator 103, and the gas containing ozone gas is led out from the gas outlet 105. At this time, the ozone gas led out from the gas lead-out port 105 is led out after being decomposed by the ozone filter 106. On the other hand, the waste ozone-containing liquid is led out from the liquid outlet 107.
 このため、配管dと配管bとの接続部C2から濾過部101に通じる経路により、洗浄液であるオゾン含有液が流動する洗浄経路が形成されることになる。また、配管aの濾過部101から接続部C1に通じる経路と配管cとにより、洗浄に利用した廃オゾン含有液が排液される排液経路が形成されることになる。ここで、洗浄経路とは、洗浄液を濾過部101に流動させる経路を意味し、排液経路とは、濾過部101の洗浄に利用した廃オゾン含有液が濾過処理装置200の外部に排液される経路を意味する。 Therefore, a cleaning path through which the ozone-containing liquid that is the cleaning liquid flows is formed by a path that leads from the connection portion C2 between the piping d and the piping b to the filtration portion 101. Further, a drainage path through which the waste ozone-containing liquid used for cleaning is drained is formed by the path leading from the filtration part 101 of the pipe a to the connection part C1 and the pipe c. Here, the cleaning path means a path for allowing the cleaning liquid to flow to the filtration unit 101, and the drainage path means that the waste ozone-containing liquid used for cleaning the filtering unit 101 is drained to the outside of the filtration processing apparatus 200. Means a route.

 図6の濾過処理装置300は、濾過部101と、洗浄に利用するオゾン含有液を生成するオゾン含有液生成器102と、洗浄に用いた後のオゾン含有液を気体と液体とに分離する第1の気液分離器103と、水などの被処理溶液が貯液された液体供給源108と、気液混合器202に供給する液体が貯液された液体供給源109と、液体を圧送する圧送部110とを備え、オゾン含有液にて濾過部101を洗浄する機能を有する。 The filtration processing apparatus 300 in FIG. 6 includes a filtration unit 101, an ozone-containing liquid generator 102 that generates an ozone-containing liquid used for cleaning, and a first unit that separates the ozone-containing liquid that has been used for cleaning into a gas and a liquid. 1 liquid-liquid separator 103, a liquid supply source 108 in which a solution to be treated such as water is stored, a liquid supply source 109 in which a liquid to be supplied to the gas-liquid mixer 202 is stored, and a liquid is pumped And a function of cleaning the filtration unit 101 with an ozone-containing liquid.
 オゾン含有液生成器102は、オゾン発生器201と、気液混合器202と、液体供給源109と、液体を圧送可能な圧送部111とを備え、オゾン発生器201により発生させたオゾンガスと、液体供給源109から圧送部111により供給された水などの液体とを気液混合器202にて混合させ、気液混合体としてのオゾン含有液を生成して配管dへ供給する。 The ozone-containing liquid generator 102 includes an ozone generator 201, a gas-liquid mixer 202, a liquid supply source 109, and a pumping unit 111 that can pump liquid, and ozone gas generated by the ozone generator 201, A liquid such as water supplied from the liquid supply source 109 by the pressure feeding unit 111 is mixed in the gas-liquid mixer 202 to generate an ozone-containing liquid as a gas-liquid mixture and supply it to the pipe d.
 オゾン発生器201には、配管eを介して気体導入口203から空気や酸素などの気体が導入される。オゾン発生器201は、オゾン発生器201内に設けられたオゾン発生素子にてオゾンガスを発生させ、発生させたオゾンガスを気体導出口204から配管fへ導出する。 In the ozone generator 201, a gas such as air or oxygen is introduced from the gas inlet 203 through the pipe e. The ozone generator 201 generates ozone gas by an ozone generation element provided in the ozone generator 201 and guides the generated ozone gas from the gas outlet port 204 to the pipe f.
 ここで、配管eは、一端がオゾン発生器の気体導入口203に接続され、もう一端が、第1の気液分離器103の気体導出口105に接続されている。このため、気液分離器103において分離された後のオゾンガスを含む気体が、配管eを介してオゾン発生器201に導入されることになる。 Here, one end of the pipe e is connected to the gas inlet 203 of the ozone generator, and the other end is connected to the gas outlet 105 of the first gas-liquid separator 103. For this reason, the gas containing the ozone gas after being separated in the gas-liquid separator 103 is introduced into the ozone generator 201 through the pipe e.
 なお、配管eには、逆止弁113が設けられ、これによりオゾン発生器201から第1の気液分離器103への気体の流動を遮り、気液分離器103の気体導出口105からオゾン発生器201への一方向においてのみ気体が流動するように構成してもよい。ここで、逆止弁とは、気体や液体などの流体が流動する配管などに取り付けられ、ある方向から逆方向への流体の流れを止めるための制御弁である。逆止弁が設けられた配管は、流体を一方向にのみ流動させることが可能となる。 In addition, the check valve 113 is provided in the pipe e, thereby blocking the flow of gas from the ozone generator 201 to the first gas-liquid separator 103, and ozone from the gas outlet 105 of the gas-liquid separator 103. You may comprise so that gas may flow only to one direction to the generator 201. FIG. Here, the check valve is a control valve that is attached to a pipe or the like through which a fluid such as gas or liquid flows and stops the flow of the fluid from a certain direction to the opposite direction. The pipe provided with the check valve can flow the fluid only in one direction.
 液体供給源109は、液体を貯液することが可能な貯液槽としての役割を担い、圧送部111を備えた配管gに接続され、気液混合器202に対して水などの液体を供給する。また、液体供給源109は、配管bと連通した配管kと接続され、液体供給源109には、配管bを流動する水などの液体が配管kを介して導入される。 The liquid supply source 109 plays a role as a liquid storage tank capable of storing liquid and is connected to a pipe g provided with a pressure feeding unit 111 to supply liquid such as water to the gas-liquid mixer 202. To do. The liquid supply source 109 is connected to a pipe k communicating with the pipe b, and a liquid such as water flowing through the pipe b is introduced into the liquid supply source 109 through the pipe k.
 気液混合器202には、配管fを介して気体導入口205からオゾンガスが導入されるとともに、配管gを介して液体導入口206から水などの液体が圧送されて導入される。気液混合器202においては、導入されたオゾンガスと水などの液体とが混合されることでオゾン含有液が生成され、生成されたオゾン含有液が導出口207から配管dに供給される。 In the gas-liquid mixer 202, ozone gas is introduced from the gas inlet 205 via the pipe f, and liquid such as water is pumped and introduced from the liquid inlet 206 via the pipe g. In the gas-liquid mixer 202, an ozone-containing liquid is generated by mixing the introduced ozone gas and a liquid such as water, and the generated ozone-containing liquid is supplied from the outlet 207 to the pipe d.
 第1の気液分離器103としては、導入された気液混合体を気体と液体とに分離する機能を有する一般的な気液分離器が利用できる。例えば、第1の気液分離器103は、液体を貯液する円筒状の貯液槽の形状のものや、配管内に気液分離器が形成された構造のものなどとして形成される。第1の気液分離器103は、配管aに連通した配管cに接続するように設けられており、これにより第1の気液分離器103には、洗浄に用いられた後のオゾン含有液が導入される。第1の気液分離器103に導入されたオゾン含有液は、第1の気液分離器103において液体と気体とに分離され、オゾンガスを含む気体は、気体導出口105から導出される。 As the first gas-liquid separator 103, a general gas-liquid separator having a function of separating the introduced gas-liquid mixture into gas and liquid can be used. For example, the first gas-liquid separator 103 is formed in the shape of a cylindrical liquid storage tank that stores liquid, or in a structure in which a gas-liquid separator is formed in a pipe. The first gas-liquid separator 103 is provided so as to be connected to a pipe c communicating with the pipe a, whereby the first gas-liquid separator 103 has an ozone-containing liquid after being used for cleaning. Is introduced. The ozone-containing liquid introduced into the first gas-liquid separator 103 is separated into liquid and gas in the first gas-liquid separator 103, and the gas containing ozone gas is led out from the gas outlet 105.
 ここで、気体導出口105は、オゾン発生器201に接続された配管eに接続され、当該配管eを介してオゾン発生器201にオゾンガスを含む気体を導入する。このため、オゾンガスを含まない酸素などの気体をもとにオゾン含有液を生成する場合に比べ、効率的に高濃度のオゾン含有液を生成できるだけでなく、高濃度のオゾンガスの大気への流出を防止できる。一方、気液分離されたオゾン溶液は、第1の気液分離器103に貯液されるか、または液体導出口107から濾過処理装置300の外部へ導出される。 Here, the gas outlet 105 is connected to a pipe e connected to the ozone generator 201, and introduces a gas containing ozone gas into the ozone generator 201 through the pipe e. For this reason, compared to the case where the ozone-containing liquid is generated based on a gas such as oxygen that does not contain the ozone gas, not only can the ozone-containing liquid be efficiently generated, but also the high-concentration ozone gas can be discharged into the atmosphere. Can be prevented. On the other hand, the gas-liquid separated ozone solution is stored in the first gas-liquid separator 103 or led out of the filtration apparatus 300 through the liquid outlet 107.
 なお、配管cには、開閉弁V4が設けられ、これにより第1の気液分離器103に導入される液体の流量を制御することが可能である。また、配管dには、開閉弁V2が設けられ、これにより濾過部101に供給されるオゾン含有液の供給量を制御することが可能である。 Note that the pipe c is provided with an on-off valve V4, whereby the flow rate of the liquid introduced into the first gas-liquid separator 103 can be controlled. In addition, the pipe d is provided with an on-off valve V2, whereby the supply amount of the ozone-containing liquid supplied to the filtration unit 101 can be controlled.
 また、配管aには、液体供給源108と、配管cが接続された部分である接続部C1との間に開閉弁V1が設けられ、これにより濾過処理装置300に導入する被処理溶液の導入量を制御することが可能である。また、配管bには、液体供給源109と接続した配管kが接続され、これにより配管bは、液体供給源109に対して配管kを介して液体を供給する機能を有している。 In addition, the pipe a is provided with an on-off valve V1 between the liquid supply source 108 and a connection portion C1 that is a part to which the pipe c is connected, thereby introducing the solution to be treated introduced into the filtration apparatus 300. It is possible to control the amount. In addition, a pipe k connected to the liquid supply source 109 is connected to the pipe b, so that the pipe b has a function of supplying a liquid to the liquid supply source 109 via the pipe k.
 配管kの一端は、配管dと配管bとの接続部C2と、外部口104との間の位置で、配管bに対して連通して接続されている。配管kのもう一端は、液体供給源109に接続されている。これにより、配管kを介して、液体供給源109に対して配管bから液体を導入することができる。また、配管bには、配管kとの接続部C3と、外部口104との間に開閉弁V3が設けられ、これにより外部口104から導出する液体の導出量を制御することができる。また、配管bには、配管dとの接続部C2と、配管kとの接続部C3との間に開閉弁V6が設けられ、これにより開閉弁V6を通る液体の流動を制御することができる。このため、開閉弁V1~V4,V6を用いることにより、濾過処理時と、洗浄時と、液体供給源109への液体供給処理時との切り替えを行なうことが可能となる。 One end of the pipe k is connected to the pipe b at a position between the connection part C2 between the pipe d and the pipe b and the external port 104. The other end of the pipe k is connected to the liquid supply source 109. Thereby, the liquid can be introduced from the pipe b to the liquid supply source 109 through the pipe k. Further, the piping b is provided with an on-off valve V3 between the connection portion C3 with the piping k and the external port 104, whereby the amount of liquid discharged from the external port 104 can be controlled. Further, the pipe b is provided with an on-off valve V6 between the connection part C2 with the pipe d and the connection part C3 with the pipe k, whereby the flow of the liquid passing through the on-off valve V6 can be controlled. . Therefore, by using the on-off valves V1 to V4, V6, it is possible to switch between the filtration process, the cleaning process, and the liquid supply process to the liquid supply source 109.
 なお、上記においては、配管cの経路と、配管aの接続部C1から液体供給源108までの経路とを、開閉弁V1と開閉弁V4とにより切り換える構成とした場合を例示したが、接続部C1に三方弁を設けることによりこれを代用することが可能である。また、上記においては、配管dの経路と、配管bの接続部C2から外部口104までの経路との切り替えを、開閉弁V2と開閉弁V6とにより切り替える構成とした場合を例示したが、同様に、接続部C2に三方弁を設けることによりこれを代用することが可能である。 In the above description, the case where the path of the pipe c and the path from the connection part C1 of the pipe a to the liquid supply source 108 are switched by the on-off valve V1 and the on-off valve V4 is illustrated. It is possible to substitute this by providing a three-way valve in C1. Moreover, in the above, the case where it was set as the structure which switches the path | route of the piping d and the path | route from the connection part C2 of the piping b to the external port 104 by the on-off valve V2 and the on-off valve V6 was illustrated, but the same In addition, it is possible to substitute this by providing a three-way valve in the connection part C2.
 <動作説明>
 次に、本実施形態に係る濾過処理装置300の動作について、図2から図4および図6を用いて説明する。濾過処理装置300は、濾過部101による被処理溶液の濾過処理の機能と、オゾン含有液生成器102の液体供給源109への液体供給処理の機能と、濾過部101の洗浄処理の機能とを備えている。
<Description of operation>
Next, operation | movement of the filtration processing apparatus 300 which concerns on this embodiment is demonstrated using FIGS. 2-4 and FIG. The filtration apparatus 300 has a function of filtering the solution to be processed by the filtration unit 101, a function of liquid supply processing to the liquid supply source 109 of the ozone-containing liquid generator 102, and a function of cleaning processing of the filtration unit 101. I have.
 濾過処理とは、濾過部101により被処理溶液を濾過する動作である。濾過処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を開状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にして、液体供給源108から水などの被処理溶液を濾過部101に供給する。 The filtration process is an operation of filtering the solution to be treated by the filtration unit 101. During the filtration process, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is opened, the on-off valve V4 is closed, and the on-off valve V6 is opened. A solution to be treated such as water is supplied to the filtration unit 101.
 濾過部101には、液体供給源108から配管aを介して水などの被処理溶液が供給され、濾過部101において濾過処理が行なわれた後に、濾過処理後の被処理溶液が濾過部101から配管bへ導出される。その後、濾過処理がなされた後の被処理溶液は、配管bに設けられた外部口104を通じて、濾過処理装置300の外部へ導出される。 A solution to be treated such as water is supplied from the liquid supply source 108 to the filtration unit 101 via the pipe a. After the filtration process is performed in the filtration unit 101, the solution to be treated after the filtration process is supplied from the filtration unit 101. It is led out to the pipe b. Thereafter, the solution to be treated after the filtration process is led out of the filtration apparatus 300 through the external port 104 provided in the pipe b.
 このため、配管bにより、濾過処理を行なった後の被処理溶液が流動する濾過経路が形成されることになる。ここで、濾過経路とは、濾過部101により濾過処理がなされた後の被処理溶液を濾過処理装置300の外部へ導出する経路を意味する。 For this reason, the piping b forms a filtration path through which the solution to be treated after the filtration treatment flows. Here, the filtration path means a path for leading the solution to be processed after the filtration process by the filtration unit 101 to the outside of the filtration apparatus 300.
 オゾン含有液生成器102の液体供給源109への液体供給処理とは、濾過部101において濾過処理した水などの被処理溶液をオゾン含有液生成器102の液体供給源109に供給する動作である。これにより、オゾン含有液を生成するために必要な液体を液体供給源109に貯液することが可能になる。 The liquid supply process to the liquid supply source 109 of the ozone-containing liquid generator 102 is an operation of supplying a solution to be processed such as water filtered by the filtration unit 101 to the liquid supply source 109 of the ozone-containing liquid generator 102. . Thereby, it is possible to store the liquid necessary for generating the ozone-containing liquid in the liquid supply source 109.
 液体供給源109への液体供給処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を閉状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にして、液体供給源108から被処理溶液を濾過部101に導入する。 At the time of liquid supply processing to the liquid supply source 109, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is closed, the on-off valve V4 is closed, and the on-off valve V6 is opened. Then, the solution to be treated is introduced into the filtration unit 101 from the liquid supply source 108.
 導入された被処理溶液は、配管aを介して濾過部101に導入され、濾過後に濾過処理済みの被処理溶液が配管bに導出される。その後、濾過処理済みの被処理溶液は、配管bおよび配管kをたどり、液体供給源109に導入される。このため、配管bと配管kとにより、液体供給源109に液体を供給する液体供給経路が形成されることになる。液体供給経路とは、濾過処理がなされた後の液体をオゾン含有液生成器102の液体供給源に109に供給する経路を意味する。 The introduced solution to be treated is introduced into the filtration unit 101 via the pipe a, and after filtration, the solution to be treated after filtration is led to the pipe b. Thereafter, the solution to be treated after filtration is introduced into the liquid supply source 109 along the pipe b and the pipe k. For this reason, the liquid supply path for supplying the liquid to the liquid supply source 109 is formed by the pipe b and the pipe k. The liquid supply path means a path for supplying the liquid after the filtering process to the liquid supply source of the ozone-containing liquid generator 102 to 109.
 洗浄処理とは、オゾン含有液生成器102にてオゾン含有液を生成し、生成したオゾン含有液を用いて濾過部101または配管を洗浄する動作である。洗浄処理時には、開閉弁V1を閉状態にし、開閉弁V2を開状態にし、開閉弁V3を閉状態にし、開閉弁V4を開状態にし、開閉弁V6を閉状態にして、オゾン含有液生成器102からオゾン含有液を濾過部101に導入し、その洗浄を行なう。 The cleaning treatment is an operation of generating an ozone-containing liquid in the ozone-containing liquid generator 102 and cleaning the filter unit 101 or the piping using the generated ozone-containing liquid. During the cleaning process, the on-off valve V1 is closed, the on-off valve V2 is opened, the on-off valve V3 is closed, the on-off valve V4 is opened, the on-off valve V6 is closed, and an ozone-containing liquid generator The ozone-containing liquid is introduced into the filtration unit 101 from 102, and cleaning is performed.
 オゾン含有液生成器102で生成したオゾン含有液は、配管dを介して配管bに導入される。その後、オゾン含有液は、配管bを介して濾過部101に導入され、濾過部101を洗浄する。 The ozone-containing liquid generated by the ozone-containing liquid generator 102 is introduced into the pipe b through the pipe d. Thereafter, the ozone-containing liquid is introduced into the filtration unit 101 via the pipe b, and the filtration unit 101 is washed.
 洗浄に用いられた後のオゾン含有液は、廃オゾン含有液として配管aおよび配管cをたどり、第1の気液分離器103に導入される。その後、廃オゾン含有液は、第1の気液分離器103において気体と液体とに分離され、オゾンガスを含む気体は、気体導出口105から配管eへ導出される。さらに、その後、オゾンガスを含む気体は、オゾン発生器201の気体導入口203からオゾン発生器201に導入され、オゾン発生器201においては、再びオゾンガスを含む気体をもとにオゾンガスが発生させられる。これにより、高濃度のオゾンガスを発生させることができ、結果として高濃度のオゾン含有液を生成することが可能となる。 The ozone-containing liquid after being used for cleaning follows the pipe a and the pipe c as a waste ozone-containing liquid and is introduced into the first gas-liquid separator 103. Thereafter, the waste ozone-containing liquid is separated into gas and liquid in the first gas-liquid separator 103, and the gas containing ozone gas is led out from the gas outlet 105 to the pipe e. Furthermore, after that, the gas containing ozone gas is introduced into the ozone generator 201 from the gas inlet 203 of the ozone generator 201, and the ozone generator 201 again generates ozone gas based on the gas containing ozone gas. As a result, high-concentration ozone gas can be generated, and as a result, a high-concentration ozone-containing liquid can be generated.
 このため、配管dと配管bとの接続部C2から濾過部101に通じる経路により、洗浄液であるオゾン含有液が流動する洗浄経路が形成されることになる。また、配管aの濾過部101から接続部C1に通じる経路と配管cとにより、洗浄に利用した廃オゾン含有液が排液される排液経路が形成されることになる。ここで、洗浄経路とは、洗浄液を濾過部101に流動させる経路を意味し、排液経路とは、濾過部101の洗浄に利用した廃オゾン含有液が濾過処理装置300の外部に排液される経路を意味する。 Therefore, a cleaning path through which the ozone-containing liquid that is the cleaning liquid flows is formed by a path that leads from the connection portion C2 between the piping d and the piping b to the filtration portion 101. Further, a drainage path through which the waste ozone-containing liquid used for cleaning is drained is formed by the path leading from the filtration part 101 of the pipe a to the connection part C1 and the pipe c. Here, the cleaning path means a path for allowing the cleaning liquid to flow to the filtration unit 101, and the drainage path means that the waste ozone-containing liquid used for cleaning the filtering unit 101 is drained to the outside of the filtration processing apparatus 300. Means a route.

The liquid stored in the liquid supply source 109 by the pumping unit 111 is supplied to the ozone-containing liquid generation unit 112, and thereby the ozone-containing liquid generation unit 112 generates an ozone-containing liquid. The generated ozone-containing liquid is supplied to the pipe d. In addition, the ozone containing liquid production | generation part 112 is comprised by the thing of the form shown in FIG.3 and FIG.4, for example.
 液体供給源109は、液体を貯液することが可能な貯液槽としての役割を担い、圧送部111を備えた配管gに接続され、オゾン含有液生成部112に対して水などの液体を供給する。また、液体供給源109は、配管bと連通した配管kと接続され、液体供給源109には、配管bを流動する水などの液体が配管kを介して導入される。 The liquid supply source 109 plays a role as a liquid storage tank capable of storing a liquid, is connected to a pipe g including a pressure feeding unit 111, and supplies liquid such as water to the ozone-containing liquid generation unit 112. Supply. The liquid supply source 109 is connected to a pipe k communicating with the pipe b, and a liquid such as water flowing through the pipe b is introduced into the liquid supply source 109 through the pipe k.
 第1の気液分離器103としては、導入された気液混合体を気体と液体とに分離する機能を有する一般的な気液分離器が利用できる。例えば、第1の気液分離器103は、液体を貯液する円筒状の貯液槽の形状のものや、配管内に気液分離器が形成された構造のものなどとして形成される。気液分離器103は、配管aに連通した配管cに接続するように設けられており、これにより第1の気液分離器103には、洗浄に用いられた後のオゾン含有液が導入される。 As the first gas-liquid separator 103, a general gas-liquid separator having a function of separating the introduced gas-liquid mixture into gas and liquid can be used. For example, the first gas-liquid separator 103 is formed in the shape of a cylindrical liquid storage tank that stores liquid, or in a structure in which a gas-liquid separator is formed in a pipe. The gas-liquid separator 103 is provided so as to be connected to a pipe c communicating with the pipe a, whereby the ozone-containing liquid after being used for cleaning is introduced into the first gas-liquid separator 103. The
 また、第1の気液分離器103は、配管bに連通した配管mと接続され、これにより配管bは、濾過部101において濾過処理がなされた後の水などの被処理溶液を第1の気液分離器103へ導出することが可能に構成されている。 The first gas-liquid separator 103 is connected to a pipe m communicating with the pipe b, whereby the pipe b removes the first solution to be treated such as water after being filtered in the filtration unit 101. The gas-liquid separator 103 can be led out.
 濾過部101をオゾン含有液で洗浄した後の状態においては、濾過部101の表面にオゾン含有液が付着した状態となる。また、図2のような構成の濾過部101を具備させた場合には、濾過部101をオゾン含有液で洗浄した後の状態において、濾過処理槽21にオゾン含有液が貯液された状態となる。そのため、洗浄処理後において直ちに濾過処理を開始した場合には、これら濾過部101に残存するオゾン含有液が被処理溶液に混合されてしまうおそれがある。 In the state after the filtration unit 101 is washed with the ozone-containing liquid, the ozone-containing liquid is attached to the surface of the filtration unit 101. In addition, in the case where the filtration unit 101 configured as shown in FIG. 2 is provided, the state in which the ozone-containing liquid is stored in the filtration treatment tank 21 in the state after the filtration unit 101 is washed with the ozone-containing liquid. Become. Therefore, when the filtration process is started immediately after the cleaning process, the ozone-containing liquid remaining in the filtration unit 101 may be mixed with the solution to be treated.
 これを解決するためには、洗浄処理が終了した後に一定時間が経過するまでオゾン含有液に含まれるオゾンを分解させてから濾過処理を開始するなどの方法が採られることになるが、本実施形態に係る濾過処理装置400にあっては、濾過処理の開始時点から、濾過部101において濾過処理が行なわれた後の一定量の被処理溶液を配管mを介して第1の気液分離器103へ導出させることで、より短時間のうちに濾過処理を行なった被処理溶液を安全に利用することができるように構成している。 In order to solve this, a method such as decomposing ozone contained in the ozone-containing liquid and starting the filtration process until a certain time elapses after the cleaning process is completed is adopted. In the filtration apparatus 400 according to the embodiment, from the start of the filtration process, a certain amount of the solution to be treated after the filtration process is performed in the filtration unit 101 via the pipe m is the first gas-liquid separator. By being derived to 103, the solution to be treated that has been filtered in a shorter time can be used safely.
 また、第1の気液分離器103に導入されたオゾン含有液は、第1の気液分離器103において液体と気体とに分離され、オゾンガスを含む気体は、気体導出口105から濾過処理装置400の外に導出される。ここで、オゾンガスを含む気体は、気体導出口105から濾過処理装置400の外へオゾンフィルタ106を介して導出されるように構成してもよい。 The ozone-containing liquid introduced into the first gas-liquid separator 103 is separated into liquid and gas in the first gas-liquid separator 103, and the gas containing ozone gas is filtered from the gas outlet 105. Derived out of 400. Here, the gas containing ozone gas may be configured to be led out from the gas outlet 105 to the outside of the filtration apparatus 400 via the ozone filter 106.
 一般的に、オゾンフィルタ106は、格子状に構成した紙やアルミニウムにオゾン分解触媒を付着させたものなどから構成され、オゾンフィルタ106を通るオゾンガスを分解する。そのため、オゾンフィルタ106を設けることにより、気体導出口105から気体を安全に放出することができる。 Generally, the ozone filter 106 is composed of paper or aluminum having an ozone decomposing catalyst attached in a lattice shape, and decomposes ozone gas passing through the ozone filter 106. Therefore, by providing the ozone filter 106, the gas can be safely discharged from the gas outlet 105.
 一方、気液分離された後のオゾン溶液は、第1の気液分離器103に貯液されるか、または液体導出口107から濾過処理装置400の外部へ導出される。 On the other hand, the ozone solution after the gas-liquid separation is stored in the first gas-liquid separator 103 or led out of the filtration apparatus 400 from the liquid outlet 107.
 なお、第1の気液分離器103においてオゾンガスを一定量貯蔵させ、オゾンガスを自然に分解させた後に濾過処理装置400の外部へ導出するように構成してもよい。 The first gas-liquid separator 103 may store a certain amount of ozone gas, and the ozone gas may be naturally decomposed and then led out of the filtration apparatus 400.
 また、図6の場合と同様に、気体導出口105にオゾンフィルタ106を設けず、気体導出口105とオゾン含有液生成部112とを配管を介して接続してもよい。例えば、オゾン含有液生成部112として図3のオゾン含有液生成部112aを利用し、気体導出口105と配管eとを接続させ、オゾンガスを含む気体がオゾン含有液生成部112aに導入されるように構成してもよい。また、例えば、オゾン含有液生成部112として図4のオゾン含有液生成部112bを利用し、気体導出口105と配管jとを接続させ、オゾンガスを含む気体がオゾン含有液生成部112bに導入されるように構成してもよい。このようにすれば、オゾンガスを含む気体がオゾン発生器201に導入されることになるため、効率的にオゾン含有液を生成できるだけでなく、高濃度のオゾンガスの大気への流出を防止することができる。 Further, as in the case of FIG. 6, the gas outlet 105 may not be provided with the ozone filter 106, and the gas outlet 105 and the ozone-containing liquid generator 112 may be connected via a pipe. For example, the ozone-containing liquid generation unit 112 is used as the ozone-containing liquid generation unit 112, the gas outlet 105 and the pipe e are connected, and a gas containing ozone gas is introduced into the ozone-containing liquid generation unit 112a. You may comprise. Further, for example, the ozone-containing liquid generator 112b of FIG. 4 is used as the ozone-containing liquid generator 112, the gas outlet 105 and the pipe j are connected, and a gas containing ozone gas is introduced into the ozone-containing liquid generator 112b. You may comprise. In this way, since the gas containing ozone gas is introduced into the ozone generator 201, not only can the ozone-containing liquid be generated efficiently, but also the outflow of high-concentration ozone gas to the atmosphere can be prevented. it can.
 なお、配管cには、開閉弁V4が設けられ、また、配管mには、開閉弁V7が設けられ、これにより第1の気液分離器103に導入される液体の流量を制御することが可能である。なお、図7においては、配管mが第1の気液分離器103に接続されているが、配管mの一端を配管cに接続させることで配管cの経路の一部を共有させた構成とし、これにより配管bから配管mおよび配管cを経由して第1の気液分離器103にオゾン含有液を導入させるようにしてもよい。 The pipe c is provided with an on-off valve V4, and the pipe m is provided with an on-off valve V7, thereby controlling the flow rate of the liquid introduced into the first gas-liquid separator 103. Is possible. In FIG. 7, the pipe m is connected to the first gas-liquid separator 103, but a part of the path of the pipe c is shared by connecting one end of the pipe m to the pipe c. Thus, the ozone-containing liquid may be introduced from the pipe b to the first gas-liquid separator 103 via the pipe m and the pipe c.
 また、配管dには、開閉弁V2が設けられ、これにより濾過部101に供給されるオゾン含有液の供給量を制御することが可能である。配管aには、液体供給源108と、配管cが接続される部分である接続部C1との間に開閉弁V1が設けられ、これにより濾過処理装置400に導入する被処理溶液の導入量を制御することが可能である。また、配管bには、液体供給源109と接続した配管kが接続され、これにより配管bは、液体供給源109に対して配管kを介して液体を供給する機能を有している。 In addition, the pipe d is provided with an on-off valve V2, whereby the supply amount of the ozone-containing liquid supplied to the filtration unit 101 can be controlled. The pipe a is provided with an on-off valve V1 between the liquid supply source 108 and a connection part C1 that is a part to which the pipe c is connected, and thereby the amount of the solution to be treated introduced into the filtration apparatus 400 can be reduced. It is possible to control. In addition, a pipe k connected to the liquid supply source 109 is connected to the pipe b, so that the pipe b has a function of supplying a liquid to the liquid supply source 109 via the pipe k.
 配管kの一端は、配管dと配管bとの接続部C2と、外部口104との間の位置で、配管bに対して連通して接続されている。配管kのもう一端は、液体供給源109に接続されている。これにより、配管kを介して、液体供給源109に対して配管bから液体を導入することができる。 One end of the pipe k is connected to the pipe b at a position between the connection part C2 between the pipe d and the pipe b and the external port 104. The other end of the pipe k is connected to the liquid supply source 109. Thereby, the liquid can be introduced from the pipe b to the liquid supply source 109 through the pipe k.
 また、配管bには、配管kとの接続部C3と、外部口104との間に開閉弁V3が設けられ、これにより外部口104から導出する液体の導出量を制御することができる。また、配管bには、配管dとの接続部C2と、配管kとの接続部C3との間に開閉弁V6が設けられ、これにより開閉弁V6を通る液体の流動を制御することができる。また、配管bには、上述したように、濾過部101と、配管dとの接続部C2との間に位置する接続部C4において、開閉弁V7を備えた配管mが接続されているため、配管bから第1の気液分離器103に液体を導入させることができる。このため、開閉弁V1~V4,V6,V7を用いることにより、濾過処理時と、洗浄処理時と、液体供給源109への液体供給処理時と、濾過部のすすぎ処理時との切り替えを行なうことが可能となる。 Also, the piping b is provided with an on-off valve V3 between the connection portion C3 to the piping k and the external port 104, whereby the amount of liquid led out from the external port 104 can be controlled. Further, the pipe b is provided with an on-off valve V6 between the connection part C2 with the pipe d and the connection part C3 with the pipe k, whereby the flow of the liquid passing through the on-off valve V6 can be controlled. . In addition, as described above, the pipe b is connected to the pipe m provided with the on-off valve V7 in the connection part C4 located between the filtration part 101 and the connection part C2 of the pipe d. Liquid can be introduced into the first gas-liquid separator 103 from the pipe b. Therefore, by using the on-off valves V1 to V4, V6, and V7, switching is performed between the filtration process, the cleaning process, the liquid supply process to the liquid supply source 109, and the rinsing process of the filtration unit. It becomes possible.
 なお、上記においては、配管cの経路と、配管aの接続部C1から液体供給源108までの経路とを、開閉弁V1と開閉弁V4とにより切り換える構成とした場合を例示したが、接続部C1に三方弁を設けることによりこれを代用することが可能である。 In the above description, the case where the path of the pipe c and the path from the connection part C1 of the pipe a to the liquid supply source 108 are switched by the on-off valve V1 and the on-off valve V4 is illustrated. It is possible to substitute this by providing a three-way valve in C1.
 <動作説明>
 次に、本実施形態に係る濾過処理装置400の動作について、図2から図4および図7を用いて説明する。濾過処理装置400は、濾過部101による被処理溶液の濾過処理の機能と、オゾン含有液生成器102の液体供給源109への液体供給処理の機能と、濾過部101の洗浄処理の機能と、濾過部のすすぎ処理の機能とを備えている。
<Description of operation>
Next, operation | movement of the filtration processing apparatus 400 which concerns on this embodiment is demonstrated using FIGS. 2-4 and FIG. The filtration apparatus 400 has a function of filtering the solution to be treated by the filtration unit 101, a function of liquid supply processing to the liquid supply source 109 of the ozone-containing liquid generator 102, a function of cleaning processing of the filtration unit 101, And a rinsing function of the filtration unit.
 濾過処理とは、濾過部101により被処理溶液を濾過する動作である。濾過処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を開状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にし、開閉弁V7を閉状態にして、液体供給源108から水などの被処理溶液を濾過部101に供給する。 The filtration process is an operation of filtering the solution to be treated by the filtration unit 101. During the filtration process, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is opened, the on-off valve V4 is closed, the on-off valve V6 is opened, and the on-off valve V7 is closed. Thus, a solution to be treated such as water is supplied from the liquid supply source 108 to the filtration unit 101.
 濾過部101には、液体供給源108から配管aを介して水などの被処理溶液が供給され、濾過部101において濾過処理が行なわれた後に、濾過処理後の被処理溶液が濾過部101から配管bへ導出される。その後、濾過処理がなされた後の被処理溶液は、配管bに設けられた外部口104を通じて、濾過処理装置400の外部へ導出される。 A solution to be treated such as water is supplied from the liquid supply source 108 to the filtration unit 101 via the pipe a. After the filtration process is performed in the filtration unit 101, the solution to be treated after the filtration process is supplied from the filtration unit 101. It is led out to the pipe b. Thereafter, the solution to be treated after the filtration process is led out of the filtration apparatus 400 through the external port 104 provided in the pipe b.
 このため、配管bにより、濾過処理を行なった後の被処理溶液が流動する濾過経路が形成されることになる。ここで、濾過経路とは、濾過部101により濾過処理がなされた後の被処理溶液を濾過処理装置400の外部へ導出する経路を意味する。 For this reason, the piping b forms a filtration path through which the solution to be treated after the filtration treatment flows. Here, the filtration path means a path for leading the solution to be processed after the filtration process by the filtration unit 101 to the outside of the filtration apparatus 400.
 オゾン含有液生成器102の液体供給源109への液体供給処理とは、濾過部101において濾過処理した水などの被処理溶液をオゾン含有液生成器102の液体供給源109に供給する動作である。これにより、オゾン含有液を生成するために必要な液体を液体供給源109に貯液することが可能になる。 The liquid supply process to the liquid supply source 109 of the ozone-containing liquid generator 102 is an operation of supplying a solution to be processed such as water filtered by the filtration unit 101 to the liquid supply source 109 of the ozone-containing liquid generator 102. . Thereby, it is possible to store the liquid necessary for generating the ozone-containing liquid in the liquid supply source 109.
 液体供給源109への液体供給処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を閉状態にし、開閉弁V4を閉状態にし、開閉弁V6を開状態にし、開閉弁V7を閉状態にして、液体供給源108から被処理溶液を濾過部101に導入する。 During the liquid supply process to the liquid supply source 109, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is closed, the on-off valve V4 is closed, and the on-off valve V6 is opened. Then, the on-off valve V7 is closed, and the solution to be treated is introduced from the liquid supply source 108 into the filtration unit 101.
 導入された被処理溶液は、配管aを介して濾過部101に導入され、濾過後に濾過処理済みの被処理溶液が配管bに導出される。その後、濾過処理済みの被処理溶液は、配管bおよび配管kをたどり、液体供給源109に導入される。このため、配管bと配管kとにより、液体供給源109に液体を供給する液体供給経路が形成されることになる。液体供給経路とは、濾過処理がなされた後の液体をオゾン含有液生成器102の液体供給源に109に供給する経路を意味する。 The introduced solution to be treated is introduced into the filtration unit 101 via the pipe a, and after filtration, the solution to be treated after filtration is led to the pipe b. Thereafter, the solution to be treated after filtration is introduced into the liquid supply source 109 along the pipe b and the pipe k. For this reason, the liquid supply path for supplying the liquid to the liquid supply source 109 is formed by the pipe b and the pipe k. The liquid supply path means a path for supplying the liquid after the filtering process to the liquid supply source of the ozone-containing liquid generator 102 to 109.
 洗浄処理とは、オゾン含有液生成器102にてオゾン含有液を生成し、生成したオゾン含有液を用いて濾過部101または配管を洗浄する動作である。洗浄処理時には、開閉弁V1を閉状態にし、開閉弁V2を開状態にし、開閉弁V3を閉状態にし、開閉弁V4を開状態にし、開閉弁V6を閉状態にし、開閉弁V7を閉状態にして、オゾン含有液生成部112からオゾン含有液を濾過部101に導入し、その洗浄を行なう。 The cleaning treatment is an operation of generating an ozone-containing liquid in the ozone-containing liquid generator 102 and cleaning the filter unit 101 or the piping using the generated ozone-containing liquid. During the cleaning process, the on-off valve V1 is closed, the on-off valve V2 is opened, the on-off valve V3 is closed, the on-off valve V4 is opened, the on-off valve V6 is closed, and the on-off valve V7 is closed. Then, the ozone-containing liquid is introduced from the ozone-containing liquid generating unit 112 into the filtering unit 101 and cleaned.
 オゾン含有液生成部112で生成したオゾン含有液は、配管dを介して配管bに導入される。その後、オゾン含有液は、配管bを介して濾過部101に導入され、濾過部101を洗浄する。 The ozone-containing liquid generated by the ozone-containing liquid generating unit 112 is introduced into the pipe b through the pipe d. Thereafter, the ozone-containing liquid is introduced into the filtration unit 101 via the pipe b, and the filtration unit 101 is washed.
 洗浄に用いられた後のオゾン含有液は、廃オゾン含有液として配管aおよび配管cをたどり、第1の気液分離器103に導入される。その後、廃オゾン含有液は、第1の気液分離器103において気体と液体とに分離され、オゾンガスを含む気体は、気体導出口105から導出される。このため、配管dと配管bとの接続部C2から濾過部101に通じる経路により、洗浄液であるオゾン含有液が流動する洗浄経路が形成されることになる。 The ozone-containing liquid after being used for cleaning follows the pipe a and the pipe c as a waste ozone-containing liquid and is introduced into the first gas-liquid separator 103. Thereafter, the waste ozone-containing liquid is separated into gas and liquid in the first gas-liquid separator 103, and the gas containing ozone gas is led out from the gas outlet 105. For this reason, the path | route which leads to the filtration part 101 from the connection part C2 of the piping d and the piping b forms the washing | cleaning path | route in which the ozone containing liquid which is a washing | cleaning liquid flows.
 また、配管aの濾過部101から接続部C1に通じる経路と配管cとにより、洗浄に利用した廃オゾン含有液が排液される排液経路が形成されることになる。ここで、洗浄経路とは、洗浄液を濾過部101に流動させる経路を意味し、排液経路とは、濾過部101の洗浄に利用した廃オゾン含有液が濾過処理装置200の外部に排液される経路を意味する。 Further, a drainage path through which the waste ozone-containing liquid used for cleaning is drained is formed by the path leading from the filtration part 101 of the pipe a to the connection part C1 and the pipe c. Here, the cleaning path means a path for allowing the cleaning liquid to flow to the filtration unit 101, and the drainage path means that the waste ozone-containing liquid used for cleaning the filtering unit 101 is drained to the outside of the filtration processing apparatus 200. Means a route.
 濾過部のすすぎ処理とは、洗浄処理時に濾過部101に付着したオゾン含有液、または濾過部101の濾過処理槽21に貯液されたオゾン含有液を除去させる処理である。オゾン含有液のすすぎ処理時には、開閉弁V1を開状態にし、開閉弁V2を閉状態にし、開閉弁V3を閉状態にし、開閉弁V4を閉状態にし、開閉弁V6を閉状態にし、開閉弁V7を開状態にして、液体供給源108から被処理溶液を濾過処理装置400に導入する。 The rinsing process of the filtration part is a process of removing the ozone-containing liquid adhering to the filtration part 101 during the cleaning process or the ozone-containing liquid stored in the filtration treatment tank 21 of the filtration part 101. During the rinsing process of the ozone-containing liquid, the on-off valve V1 is opened, the on-off valve V2 is closed, the on-off valve V3 is closed, the on-off valve V4 is closed, and the on-off valve V6 is closed. V7 is opened, and the solution to be treated is introduced from the liquid supply source 108 into the filtration apparatus 400.
 液体供給源108から配管aを介して濾過部101に供給された水などの被処理溶液は、濾過部101に付着したオゾン含有液を除去するか、または濾過部101の濾過処理槽21に貯液されたオゾン含有液を被処理溶液に置き換え、除去または置き換えられたオゾン含有液は、配管bおよび配管mを介して第1の気液分離器103へ導入され、第1の気液分離器103の液体導出口107から濾過処理装置400の外部へ導出される。これにより、洗浄処理後において濾過部101に残存するオゾン含有液が、その後に実施される濾過処理時において外部を導出することが防止できる。 The solution to be treated such as water supplied from the liquid supply source 108 to the filtration unit 101 via the pipe a removes the ozone-containing liquid adhering to the filtration unit 101 or is stored in the filtration treatment tank 21 of the filtration unit 101. The liquefied ozone-containing liquid is replaced with the solution to be treated, and the removed or replaced ozone-containing liquid is introduced into the first gas-liquid separator 103 via the pipe b and the pipe m, and the first gas-liquid separator It is led out of the filtration processing apparatus 400 from the liquid outlet 107 of 103. As a result, it is possible to prevent the ozone-containing liquid remaining in the filtration unit 101 after the cleaning process from leading to the outside during the subsequent filtration process.
 このため、配管bの濾過部101から接続部C4に通じる経路と配管mとにより、濾過部101に残存するオゾン含有液が排液される経路が形成されることになる。なお、オゾン含有液を除去することが可能となるすすぎ処理の時間は、濾過部101の形状や大きさ等に伴って適宜設定すればよい。 For this reason, a path through which the ozone-containing liquid remaining in the filtration part 101 is drained is formed by the path from the filtration part 101 of the pipe b to the connection part C4 and the pipe m. In addition, what is necessary is just to set the time of the rinse process which can remove an ozone containing liquid suitably with the shape of the filtration part 101, a magnitude | size, etc. FIG.
