Description
本発明は、有機物質を含有する水から有機物質を除去して浄化する装置に関し、特に各種工場、研究施設等から排出される有機溶剤等の有機物質を含有した産業排水の浄化に用いられる水処理システムに関する。 The present invention relates to an apparatus for removing and purifying organic substances from water containing organic substances, and in particular, water used for the purification of industrial wastewater containing organic substances such as organic solvents discharged from various factories and research facilities. It relates to a processing system.
従来より、有害有機物質を水から除去して浄化する装置としては、活性炭等の吸着材を用いた交換式吸着装置が広く用いられている。すなわち、活性炭等の吸着材を充填した槽に有機物質を含有した水を通流させ、吸着材により水中の有害有機物質を効率的に除去する事ができるシンプルな処理装置である。しかしながら、交換式吸着装置は有害有機物質を一定時間吸着し続け、吸着材の吸着能力が飽和に達すれば、新品への交換もしくは一度装置から吸着材を取り出して再生が必要となって連続浄化できず、更に、水の浄化は、空気の浄化と異なり、微生物の繁殖が不可避であり、吸着剤の寿命を縮めることもあって、交換および再生への労力、コストの増大が問題となり、また人的作業機会が多いため、フィルター交換時等に、有害有機物質が作業員の健康・安全に悪影響を及ぼすこともあった。かかる問題を解決するため、多量の吸着剤を用いることで、交換周期を延長させることも考えられるが、装置の大型化、設備投資が不可避となる。また、吸着剤である活性炭の表面を適度に疎水化させる等の吸着能力を向上させることも検討されているが（例えば特許文献１参照）、微量の有害物質を除去する場合には有効であっても、多量の有害有機物質を高い効率で処理することが要請される場合には根本的な解決手段になっておらず、特に研究所や工場等で用いる場合に満足できるものではなかった。また、従来の浄化装置では、吸着剤使用開始時と使用終了前（吸着剤取替え直前）では有害物質吸着性能が変化しており、安定に浄化処理することができないという問題点も有していた。 Conventionally, as an apparatus for removing harmful organic substances from water and purifying it, an exchangeable adsorption apparatus using an adsorbent such as activated carbon has been widely used. That is, it is a simple treatment apparatus that allows water containing an organic substance to flow through a tank filled with an adsorbent such as activated carbon and efficiently removes harmful organic substances in water by the adsorbent. However, the exchangeable adsorption device continues to adsorb toxic organic substances for a certain period of time, and if the adsorption capacity of the adsorbent reaches saturation, it can be continuously replaced by replacing it with a new one or removing the adsorbent from the device and regenerating it once. In addition, unlike the purification of air, the purification of water is unavoidable for the growth of microorganisms, and the life of the adsorbent may be shortened. Due to the large number of work opportunities, harmful organic substances may adversely affect the health and safety of workers when replacing filters. In order to solve such a problem, it is conceivable to extend the replacement cycle by using a large amount of adsorbent, but it is inevitable to enlarge the apparatus and invest in the equipment. In addition, although it has been studied to improve the adsorption ability such as appropriately hydrophobizing the surface of the activated carbon as an adsorbent (see, for example, Patent Document 1), it is effective in removing a trace amount of harmful substances. However, it is not a fundamental solution when it is required to treat a large amount of harmful organic substances with high efficiency, and it is not satisfactory particularly when used in laboratories and factories. In addition, the conventional purification apparatus has a problem that the toxic substance adsorption performance changes between the start of use of the adsorbent and before the end of use (immediately before the replacement of the adsorbent), and the purification process cannot be stably performed. .
本発明は、従来技術の課題を背景になされたもので、水の連続浄化を実現し、基本的に吸着剤の交換が必要なく、多量の有害有機物質を高効率で吸着除去し、人的作業を介することなく、有害有機物質の分解することができる処理システムを提供することを課題とするものである。 The present invention has been made against the background of the problems of the prior art. It realizes continuous purification of water, basically eliminates the need to replace the adsorbent, and adsorbs and removes a large amount of harmful organic substances with high efficiency. It is an object of the present invention to provide a treatment system capable of decomposing harmful organic substances without involving work.

Therefore, there is an advantage that harmful organic substances in water can be removed stably and safely with high throughput and low cost.
本発明にかかる水処システムは、有機物質を含有する水を吸着素子に通流させて該吸着素子に有機物質を吸着させる吸着工程設備と、該吸着素子に高温の加熱ガスを通流させて該吸着素子に吸着された有機物質を脱着する脱着工程設備を備え、かかる工程を交互に行う水処理装置と該水処理装置の脱着工程にて発生したガスを処理するガス燃焼分解処理装置とを備えた水処理システムシステムであることが好ましい。かかる構造を採用することにより、有害有機物質の吸着・脱着・分解の一連の処理を、人的作業を介することなく、連続的におこなうことができるからである。 The water treatment system according to the present invention includes an adsorption process facility for allowing water containing an organic substance to flow through an adsorbing element and adsorbing the organic substance to the adsorbing element, and a high-temperature heating gas to flow through the adsorbing element. A desorption process facility for desorbing the organic substance adsorbed on the adsorption element, and a water treatment apparatus that alternately performs the process and a gas combustion decomposition treatment apparatus that processes gas generated in the desorption process of the water treatment apparatus It is preferable that the water treatment system system is provided. This is because by adopting such a structure, a series of treatments of adsorption, desorption, and decomposition of harmful organic substances can be performed continuously without human work.
好ましい水処理装置の構造としては、吸着素子が回転することができ、吸着工程で有機物質を吸着した吸着素子の部位が、吸着素子の回転により、脱着工程へ移動する構造を有する水処理装置である。かかる構造であれば、容易且つ安定に有害有機物質の吸着・脱着をおこなえるからである。 As a preferable water treatment apparatus structure, the adsorption element can rotate, and the part of the adsorption element that adsorbs the organic substance in the adsorption process moves to the desorption process by the rotation of the adsorption element. is there. This is because such a structure makes it possible to adsorb and desorb harmful organic substances easily and stably.
前記水処理装置の脱着工程により発生した有機物質を含有したガスを処理するガス燃焼分解処理装置は、特に限定されるものではないが、ガスを６５０〜８００℃の高温で直接酸化分解する直接燃焼装置や、触媒を使用してガスを触媒酸化反応させて酸化分解する触媒燃焼装置や、蓄熱体を使用して熱回収を行い経済的に直接酸化分解する蓄熱式直接燃焼装置や蓄熱式触媒燃焼装置であってもよい。このような装置であれば、高効率・連続的に有害有機物質を分解処理できるからである。 The gas combustion decomposition treatment apparatus for treating the gas containing the organic substance generated by the desorption process of the water treatment apparatus is not particularly limited, but direct combustion that directly oxidizes and decomposes the gas at a high temperature of 650 to 800 ° C. Equipment, catalytic combustion equipment that catalyses and oxidatively decomposes gas using a catalyst, thermal storage direct combustion equipment and thermal storage catalytic combustion that recovers heat using a heat storage body and economically oxidatively decomposes It may be a device. This is because such an apparatus can continuously decompose harmful organic substances with high efficiency.
以下、図面を参照して、本発明にかかる水処理システムについて詳細に説明する。図２は本発明の好ましい実施形態の例である。図２に例示した水処理装置は、有害有機物質を含有した水を、原水導入ライン２１を通じて図３に例示した円柱状または図４に例示した円筒状に形成された吸着素子２２の吸着領域２３に送られ、吸着材により有機物質を吸着除去して浄化水として排出する吸着工程を有する。
Hereinafter, a water treatment system according to the present invention will be described in detail with reference to the drawings. FIG. 2 is an example of a preferred embodiment of the present invention. The water treatment apparatus illustrated in FIG. 2 has an
一方で前記吸着素子２２は回転し、パージ領域２４に送られ、ガスの通流により吸着素子表面に残存する水滴を除去するパージ工程を有することが好ましい。水滴を気流で除去することにより、加熱による有害有機物質の脱着が容易になるからである。パージガスを高温加熱気流とすることにより、後述する脱着工程を同時におこなってもよいが、エネルギーコスト等から考えて、パージ工程と脱着工程を別にすることが好ましい。
On the other hand, it is preferable that the adsorption element 22 has a purge process in which the adsorption element 22 rotates and is sent to the
ここで除去された水は、有機物質を含むものであり、集積して焼却等してもよいが、戻りライン２５より装置入口の有機物質を含有する原水に戻すことが好ましい。かかる方法によれば、工程数を省略でき、効率的だからである。
The water removed here contains an organic substance and may be accumulated and incinerated. However, it is preferable to return to the raw water containing the organic substance at the inlet of the apparatus from the
また、吸着素子２２は回転し、パージ工程の後工程で脱着領域２６にて加熱ガスにより吸着素子を加熱する事で吸着した有害物質を脱着して再度吸着が行える状態に再生される脱着工程を有することが好ましい。加熱により有害有機物質を脱着した後、連続的に吸着工程に移動することができるからである。脱着工程により発生した有機物質を含有したガスは、直接燃焼装置や触媒燃焼装置、蓄熱式燃焼装置等の燃焼装置や活性炭素繊維を使用した溶剤回収装置等の一般的に用いられるガス処理装置にて処理する事ができる。
Further, the adsorption element 22 is rotated, and a desorption process is performed in which the adsorbed harmful substance is desorbed by heating the adsorption element with a heating gas in the
前記水処理装置の脱着工程で発生したガスの処理は、熱交換機器を経由して白金触媒２７を備えた触媒反応器２８に送られ、ガスを触媒酸化反応させて該ガス中の有機物質を分解除去する触媒燃焼装置を用いる。
The treatment of the gas generated in the desorption process of the water treatment device is sent to a
かかる連続的な吸着−加熱脱着−分解により、低コストで、安定且つ安全に、高い能力で水中の有害有機物質を除去処理することができ、更には藻等の発生を防ぐことができる。 By such continuous adsorption-heat desorption-decomposition, it is possible to remove and remove harmful organic substances in water with high performance at a low cost, stably and safely, and to prevent generation of algae and the like.
本発明にかかる吸着素子の構造は、特に限定されるものではなく、粒状物を充填したもの、繊維状物を不織布等にしたもの等であってもよいが、図１に例示したハニカム状構造を有することが特に好ましい。ハニカム状構造とすることにより、粒状や繊維状に比べて圧力損失を極めて低くなり、処理能力を増大させることができ、ゴミ等の固形物による目詰まりが起こりにくく、更にはパージ工程においてガスの流通により吸着素子表面の水滴を除去する際にも、容易に水滴の除去が可能となるからである。 The structure of the adsorbing element according to the present invention is not particularly limited, and may be one filled with a granular material, one made of a fibrous material into a non-woven fabric, or the like, but the honeycomb-like structure illustrated in FIG. It is particularly preferred to have By adopting a honeycomb-like structure, pressure loss is extremely low compared to granular and fibrous forms, the processing capacity can be increased, clogging due to solids such as dust is less likely to occur, and further, gas in the purge process This is because even when water droplets on the surface of the adsorption element are removed by circulation, the water droplets can be easily removed.
本発明にかかる、吸着素子の運転は、連続的であることが好ましいが、除去すべき有害有機物質の量、処理水の量等を勘案して、間欠運転としてもよい。有害有機物質の量があるいは処理水の量が少ないような条件では、連続運転であることまで要求されず、運転コストを削減できるからである。 Although the operation of the adsorption element according to the present invention is preferably continuous, it may be intermittent operation in consideration of the amount of harmful organic substances to be removed, the amount of treated water, and the like. This is because, under the condition that the amount of harmful organic substances or the amount of treated water is small, it is not required that the operation is continuous, and the operation cost can be reduced.
本発明で用いる吸着剤は特に限定されるものではないが、活性炭またはゼオライトが水中での有害有機物質の吸着性能に優れており好ましい。中でもゼオライトは、親水性ゼオライトおよび疎水性ゼオライトがあるが、疎水性ゼオライトがより好ましい。これは、疎水性ゼオライトは親水性ゼオライトに比べてＳｉ／Ａｌ比（モル比）が高い事で水分吸着率が低く、水よりも有機物質を優先的に吸着できる特徴があり、水中での有機物質の吸着性能がより優れているからである。また、疎水性ゼオライトは耐熱温度が著しく高く、脱着工程に置いてより高温の加熱空気を使用する事ができ、分子量が大きく、沸点の高い高温でしか脱着出来ない有機物質の場合でも適応が可能となるという効果も有する。 The adsorbent used in the present invention is not particularly limited, but activated carbon or zeolite is preferable because of its excellent ability to adsorb harmful organic substances in water. Among them, zeolites include hydrophilic zeolite and hydrophobic zeolite, and hydrophobic zeolite is more preferable. This is because hydrophobic zeolite has a low water adsorption rate due to its high Si / Al ratio (molar ratio) compared to hydrophilic zeolite, and can adsorb organic substances preferentially over water. This is because the adsorption performance of the substance is more excellent. Hydrophobic zeolite has a remarkably high heat-resistant temperature, and can use heated air at a higher temperature in the desorption process, and can be applied even to organic substances that have a high molecular weight and can be desorbed only at high temperatures with high boiling points. It also has the effect of becoming.
また、本発明にかかる装置に用いる吸着素子は、フッ素、シリコン、炭化水素系化合物により撥水処理されている事が好ましい。かかる処理を施すことにより、脱着工程における加熱処理の際、水の蒸発潜熱に必要とされるエネルギーを低減することができ、有害有機物質の脱着を容易にし、更には水よりも優先的に有機溶剤等の有害物質を選択的に吸着するようになり吸着性能が向上するという効果をも有するからである。特に好ましい処理剤はフッ素である。 The adsorbing element used in the apparatus according to the present invention is preferably water-repellent treated with fluorine, silicon, or a hydrocarbon compound. By performing such a treatment, the energy required for the latent heat of vaporization during the heat treatment in the desorption process can be reduced, desorption of harmful organic substances can be facilitated, and organic matter is given priority over water. This is because a harmful substance such as a solvent is selectively adsorbed and the adsorbing performance is improved. A particularly preferred treating agent is fluorine.

Raw water containing 20 ppm of toluene was supplied at 25 ° C. at a flow rate of 3 m 3 / min, and the toluene concentration at the outlet of each water treatment apparatus after 10 hours and 500 hours of operation was measured.
(Toluene concentration evaluation)
Analysis and measurement were performed by gas chromatography.
〔実施例〕
吸着材としてＳｉ／Ａｌ比（モル比）が１０００で平均細孔径５．５Å、比表面積４００ｍ2／ｇのＺＳＭ−５型の疎水性ゼオライトを５０重量％含有し、撥水剤として４フッ化エチレン樹脂を２５ｗｔ％含有し、吸着領域、パージ領域、脱着領域に区分された４５０ｍｍΦの直径で、厚み４５０ｍｍの重量２０ｋｇの円柱状のハニカム状構造を有する吸着素子を使用した水処理装置に原水を導入した。
〔Example〕
Contains 50% by weight of ZSM-5 type hydrophobic zeolite having an Si / Al ratio (molar ratio) of 1000, an average pore diameter of 5.5 mm, and a specific surface area of 400 m 2 / g as an adsorbent, and tetrafluoride as a water repellent. Raw water is supplied to a water treatment apparatus containing an adsorption element containing 25 wt% of an ethylene resin and having a columnar honeycomb-like structure with a diameter of 450 mmΦ and a thickness of 450 mm divided into an adsorption region, a purge region, and a desorption region. Introduced.
水処理装置の脱着工程における加熱ガスとして１８０℃の空気を使用し、脱着の風量は１ｍ3／ｍｉｎとした。また、パージ工程おいては、空気を０．３ｍ3／ｍｉｎで流した。また、吸着素子の回転数は２ＲＰＨの周期で回転させた。 180 ° C. air was used as a heating gas in the desorption process of the water treatment apparatus, and the desorption air flow was 1 m 3 / min. In the purge process, air was flowed at 0.3 m 3 / min. Further, the rotation speed of the adsorption element was rotated at a cycle of 2 RPH.
脱着工程で発生したガスを、白金触媒を使用した触媒燃焼装置に導入し触媒入口温度を３００℃にして触媒酸化分解処理を実施して処理した。 The gas generated in the desorption process was introduced into a catalytic combustion apparatus using a platinum catalyst, and the catalyst inlet temperature was set to 300 ° C. to perform catalytic oxidative decomposition treatment.
本実施例の水処理システムにより浄化された水は、１０時間後、５００時間後、共にトルエン濃度が１ｐｐｍ以下であり、吸着と脱着を連続して行い処理するため、性能低下がなく安定して高い効率で処理ができた。更には、システム内のトルエンの存在は、吸着素子の一部に付着されているだけであり、このような微量のトルエンも、吸着素子質原水の導入を止めて、システムを運転し、有害有機物質の脱着−分解をおこなうことによってほぼ完全に除去することができ、作業員が直接にトルエンに接触する機会は無かった。 The water purified by the water treatment system of this example had a toluene concentration of 1 ppm or less after 10 hours and after 500 hours, and was treated by performing adsorption and desorption continuously, so there was no degradation in performance and stability. Processing was possible with high efficiency. Furthermore, the presence of toluene in the system is only attached to a part of the adsorbing element, and such a trace amount of toluene also stops the introduction of the adsorbing element quality raw water, operates the system, The material could be almost completely removed by desorption-decomposition and there was no opportunity for workers to contact toluene directly.
〔比較例〕
０．１１ｍ３の吸着層に平均細孔径１６Å、比表面積１０００ｍ2／ｇで充填密度４５０ｇ／ｌの円柱状の椰子殻活性炭を５０ｋｇ充填した交換式吸着方式の水処理装置に原水を導入した。
[Comparative Example]
Raw water was introduced into a water treatment apparatus of an exchange type adsorption system in which 50 kg of cylindrical coconut shell activated carbon having an average pore diameter of 16 mm, a specific surface area of 1000 m 2 / g and a packing density of 450 g / l was packed in a 0.11 m 3 adsorption layer.
本比較例の水処理装置により浄化された水は、１０時間後のトルエン濃度が１ｐｐｍ以下であったが、５００時間後にはトルエン濃度が入口と同じ２０ｐｐｍであり、安定して高い効率で処理する事ができなった。これは実施例と異なり比較例は吸着のみの操作で吸着と再生を連続して実施しないために、直ぐに吸着材の吸着能力が飽和に達してしまうからである。また吸着剤を取り出す際、吸着剤にはトルエンが含まれており、防護具を必要とした。 The water purified by the water treatment apparatus of this comparative example had a toluene concentration of 1 ppm or less after 10 hours, but after 500 hours, the toluene concentration was 20 ppm, the same as the inlet, and was treated stably and with high efficiency. I could n’t do it. This is because, unlike the example, the comparative example does not continuously perform adsorption and regeneration by an operation of only adsorption, so that the adsorption capacity of the adsorbent immediately reaches saturation. When removing the adsorbent, the adsorbent contained toluene and required protective equipment.
本発明の水処理システムは、水の連続浄化を実現し、基本的に吸着剤の交換が必要なく、多量の有害有機物質を高効率且つ安定に除去・分解することができるため、設備増大を必要とせずに、吸着剤交換作業を省略でき、コスト低減、有害物質安定除去、作業者の安全を実現でき、特に研究所や工場等の幅広い分野に利用することができ、産業界に寄与することが大である。 The water treatment system of the present invention realizes continuous purification of water, basically does not require replacement of the adsorbent, and can remove and decompose a large amount of harmful organic substances with high efficiency and stability. Adsorbent replacement work can be omitted without need, cost reduction, stable removal of harmful substances, and safety of workers can be realized, and it can be used in a wide range of fields such as laboratories and factories, contributing to the industry. That is big.
