Description
【０００１】[0001]
本考案は、水処理を単独のオゾン処理器で行った場合に正起する強い酸化力を もつＯＨラジカルの遊離基捕獲剤によるトラップという障害を解決する複合型水 処理システムに関するものである。 The present invention relates to a combined water treatment system that solves the problem of trapping an OH radical having a strong oxidizing power by a free radical scavenger that occurs when water treatment is performed by a single ozone treatment device.
【０００２】[0002]
近年、多くの人々の高い関心の的になっている水の汚染が進んでおり、そのよ うな社会環境の中で、上水や下水や冷却環境水などに含まれる細菌、ウイルス、 藻類、藻類から代謝されるカビ臭物質、無機物質、ならびに難分解性物質の除去 が重要な課題となっている。オゾン処理はこれらの汚染物質の殺菌、殺藻、微生 物の酸化分解、脱色、除去等に極めて有効である。 In recent years, water pollution, which has been of great interest to many people, is progressing, and in such a social environment, bacteria, viruses, algae, algae contained in clean water, sewage and cooling environment water are included. The removal of musty odorous substances, inorganic substances, and persistent substances that are metabolized from plants is an important issue. Ozone treatment is extremely effective in sterilizing these pollutants, killing algae, oxidatively decomposing, decolorizing and removing microbes.
【０００３】 水中に溶解している汚染物質とオゾンとの反応は、汚染物質のオゾン分子によ る直接的な酸化と、オゾンから生成したＯＨラジカルによる汚染物質の酸化とい う２つの反応形式に大別できる。The reaction between ozone and pollutants dissolved in water is divided into two reaction modes: direct oxidation of pollutants by ozone molecules and oxidation of pollutants by OH radicals generated from ozone. It can be roughly divided.
【０００４】 ＯＨラジカルはオゾンよりも酸化力（他の分子などから電子を奪いやすい性質 ）が強い。例えば、ＯＨラジカルのベンゼンの酸化の反応速度定数は、オゾンよ りも１０9倍大きい。またＯＨラジカルは、細菌や微生物の殺菌に代表されるよ うに、その強い酸化力によって汚染物質を酸化分解することができ、オゾン処理 器による水処理において、ＯＨラジカルはオゾン分子より重要な役割を担ってい る。OH radicals have a stronger oxidizing power (property of easily depriving electrons from other molecules) than ozone. For example, the reaction rate constant for the oxidation of OH radicals into benzene is 10 9 times greater than ozone. In addition, OH radicals can oxidize and decompose pollutants due to their strong oxidizing power, as represented by the sterilization of bacteria and microorganisms, and OH radicals play a more important role than ozone molecules in water treatment by ozone treatment equipment. I am responsible.
【０００５】[0005]
しかし、処理対象の水中に炭酸やその塩類の電離によってＣＯ3 2-やＨＣＯ3 - のような遊離基捕獲剤が存在すると、ＯＨラジカルがこれらに捕獲されてしまい 、水中の汚染物質の酸化分解処理にＯＨラジカルを有効に利用できない。処理対 象の水中に大量のＣＯ3 2-やＨＣＯ3 -が存在すると、オゾン分子による酸化反応 が優先されるが、処理効率が著しく低下する。However, if free radical scavengers such as CO 3 2− and HCO 3 − are present in the water to be treated due to ionization of carbonic acid and its salts, OH radicals are trapped by these and oxidative decomposition of pollutants in the water is caused. OH radicals cannot be effectively used for processing. If a large amount of CO 3 2− or HCO 3 − exists in the water to be treated, the oxidation reaction by ozone molecules will be prioritized, but the treatment efficiency will be significantly reduced.
【０００６】 特に冷却循環水の場合、熱交換作用によって水中のカルシウム塩類、マグネシ ウム塩類、ＣＯ3 2-、ＨＣＯ3 -や有機物が通常の水よりも２〜４倍濃縮され、そ の結果、配管等に微生物や水垢が発生する。Particularly in the case of cooling circulating water, calcium salts, magnesium salts, CO 3 2− , HCO 3 − and organic substances in the water are concentrated 2 to 4 times more than ordinary water by the heat exchange action, and as a result, Microorganisms and scale are generated on the piping.
【０００７】 これらを除去及び防止するためにオゾン処理システムが導入されているが、上 記のように冷却循環水にはＣＯ3 2-やＨＣＯ3 -のような遊離基捕獲剤が上水に比 較して大量に存在するのでＯＨラジカルが捕獲されてしまう。これにより水中の 汚染物質の酸化分解は主にオゾン分子によって行われ、水垢や微生物の除去の効 率が低下する。Although an ozone treatment system has been introduced to remove and prevent these, free radical scavengers such as CO 3 2− and HCO 3 − are added to tap water in the cooling circulating water as described above. Since a large amount of OH radicals are present, OH radicals are trapped. As a result, the oxidative decomposition of pollutants in water is mainly carried out by ozone molecules, which reduces the efficiency of removing scale and microorganisms.
【０００８】 また上水分野において現在は軟水が使用されているが、水源の汚染や水不足に より硬水を使用する可能性がある。したがって、水のオゾン処理の効率を低下さ せないようにオゾンの注入率を高くする必要があり、紫外線や放射線の照射や過 酸化水素を添加することによって、ＯＨラジカルの生成を促進する試みがこれま でに活発になされている。Although soft water is currently used in the water supply field, there is a possibility that hard water will be used due to pollution of the water source or water shortage. Therefore, it is necessary to increase the ozone injection rate so as not to reduce the efficiency of ozone treatment of water, and it has been attempted to accelerate the generation of OH radicals by irradiating ultraviolet rays or radiation or adding hydrogen peroxide. It has been active so far.
【０００９】 処理対象水への紫外線照射は図１に示した中圧二重円筒型紫外線装置を用いて 、水を外管と石英できている内管の間隙を通過させることによって行われている が、構造が複雑なことやランプ寿命が短い等の問題があり、その大規模化は極め て困難である。Irradiation of the water to be treated with ultraviolet rays is carried out by passing the water through the gap between the outer tube and the inner tube made of quartz using the medium pressure double cylinder type ultraviolet device shown in FIG. However, there are problems that the structure is complicated and the lamp life is short, and it is extremely difficult to increase the scale.
【００１０】 同様に放射線照射の装置系においても多くの問題をかかえている。ＯＨラジカ ルの生成を促進するために過酸化水素を添加する方法では、過酸化物質などの副 生成物が生じ、それらの処理が困難であるという問題がある。Similarly, the radiation irradiation system has many problems. The method of adding hydrogen peroxide in order to accelerate the production of OH radicals has a problem that by-products such as peroxides are generated and it is difficult to treat them.
【００１１】 本考案は、上述した問題に鑑みてなされたもので、その目的とするところは、 処理対象の水中に存在するＣＯ3 2-やＨＣＯ3 -のような遊離基捕獲剤や電導性物 質および溶存酸素や溶存二酸化炭素をオゾン処理する前に除去し、残存する細菌 、ウイルス、藻類、藻類から代謝されるカビ臭物質、有機物質、無機物質、なら びに難分解性物質をＯＨラジカルの強い酸化力によって酸化分解し、さらにアン モニア等を除去するという新しい水の処理方法を提供するにある。The present invention has been made in view of the above problems, and an object thereof is to provide a free radical scavenger such as CO 3 2− and HCO 3 − existing in the water to be treated or a conductive material. OH radicals are removed by removing substances and dissolved oxygen and dissolved carbon dioxide before ozone treatment, and remaining bacteria, viruses, algae, musty odor substances metabolized from algae, organic substances, inorganic substances, and persistent substances. It is to provide a new water treatment method of oxidizing and decomposing by the strong oxidizing power of ammonium and further removing ammonia and the like.

上記目的を達成するため、請求項１記載の考案は、処理対象水に通電を行うこ とにより前記処理対象水中に含有される水垢成分を除去する水垢除去装置と、水 垢除去処理を施された前記処理対象水にオゾンを注入するオゾン注入装置とを備 えたことを特徴とする水処理装置を提供する。 In order to achieve the above object, the device according to claim 1 is provided with a scale removing device for removing scale components contained in the target water by energizing the target water, and a scale removing treatment. Also provided is an ozone injecting device for injecting ozone into the water to be treated.
【００１３】 請求項２記載の考案は、処理対象水に通電を行うことにより前記処理対象水中 に含有される水垢成分を除去する水垢除去装置と、前記水垢除去処理された処理 対象水の脱気を行う脱気装置と、前記脱気処理された処理対象水にオゾンを注入 してオゾン処理を行うオゾン処理装置と、前記脱気装置にて発生する排ガスを、 前記オゾン処理された処理対象水に注入する排ガス注入装置と、前記排ガスを注 入された処理対象水に生物活性炭処理を行う生物活性炭処理装置とを有する水処 理装置を提供する。According to a second aspect of the invention, a scale removing device for removing scale components contained in the treatment target water by energizing the treatment target water, and degassing of the treatment target water subjected to the scale removal treatment. A degassing device for performing the ozone treatment, an ozone treatment device for performing ozone treatment by injecting ozone into the degassed water to be treated, and an exhaust gas generated in the degassing device, There is provided a water treatment device having an exhaust gas injection device for injecting the exhaust gas, and a biological activated carbon treatment device for performing biological activated carbon treatment on the water to be treated into which the exhaust gas has been injected.
【００１４】 上記のように、水垢除去装置とオゾン処理器を連結することによってオゾン処 理を効率良く行うことができる。特に、本願の出願人が先に提案した特公昭１４ １６４５５号及び特公昭６３−３８４４０号公報に記載されている電気電解法を 用いた電気水垢処理器を用いることにより、処理対象の水中に存在するＣＯ3 2- やＨＣＯ3 -のような遊離基捕獲剤や伝導性物質及び溶存二酸化炭素をオゾン処理 する前に効率的に除去することができる。As described above, the ozone treatment can be efficiently performed by connecting the scale removing device and the ozone treatment device. In particular, by using the electric scale treatment apparatus using the electrolysis method described in Japanese Patent Publication No. 16455/1988 and Japanese Patent Publication No. 63-38440 previously proposed by the applicant of the present application, the presence in the water to be treated Free radical scavengers such as CO 3 2− and HCO 3 − , conductive substances and dissolved carbon dioxide can be efficiently removed before ozone treatment.
【００１５】 その後にオゾン処理装置で処理水に残存する細菌、ウイルス、藻類、藻類から 代謝されるカビ臭物質、有機物質、無機物質、ならびに難分解性物質をオゾン処 理器を用いて、ＯＨラジカルの強い酸化力によってこれらの汚染物質を酸化分解 することができる。Thereafter, bacteria, viruses, algae, musty odor substances metabolized from algae, organic substances, inorganic substances, and hardly decomposable substances remaining in the treated water in the ozone treatment apparatus are treated with OH by using an ozone treatment device. The strong oxidizing power of radicals can oxidize and decompose these pollutants.
【００１６】 特に、電気分解時に脱気装置から排出される酸素や炭酸ガスをオゾン処理後の 水に注入し、それを生物活性炭処理することによって、アンモニア等を除去する という新しい複合型水処理システムを用いて水を浄化することができる。In particular, a new composite water treatment system that removes ammonia and the like by injecting oxygen and carbon dioxide gas discharged from the deaerator during electrolysis into ozone-treated water and treating it with biological activated carbon. Can be used to purify water.
【００１７】 上記のように電気水垢処理器で水を前処理することにより、溶存酸素や溶存二 酸化炭素を除去することができる。従ってオゾンが効率よく溶解し、強い酸化力 を有するＯＨラジカルになる。By pretreating water with the electric scale treatment device as described above, dissolved oxygen and dissolved carbon dioxide can be removed. Therefore, ozone is efficiently dissolved and becomes an OH radical having a strong oxidizing power.
【００１８】 さらにＣＯ3 2-やＨＣＯ3 -のような遊離基捕獲剤も電解後の水中に存在しない ので、強い酸化力をもつＯＨラジカルが効率よく汚染物を酸化分解でき、またオ ゾン処理後の水を生物活性炭処理する際に電気分解時に脱気装置から排出される 酸素や炭酸ガスが効率良く活用することができる。Furthermore, since free radical scavengers such as CO 3 2− and HCO 3 − do not exist in water after electrolysis, OH radicals having a strong oxidizing power can efficiently oxidatively decompose pollutants, and the ozone treatment. Oxygen and carbon dioxide gas discharged from the degassing unit during electrolysis can be efficiently used when the subsequent water is treated with biological activated carbon.
【００１９】[0019]
以下、本考案の実施例を詳細に説明するが、本考案は以下の実施例に限定され るものではない。 Hereinafter, embodiments of the present invention will be described in detail, but the present invention is not limited to the following embodiments.
【００２０】 本実施例で用いた複合型水処理システムの装置は、電気水垢処理部、脱気部、 オゾン発生部、オゾン処理部と生物活性炭処理部の５部から構成されている。そ の説明図を図１に示す。The apparatus of the composite type water treatment system used in this example is composed of an electric scale treatment unit, a deaeration unit, an ozone generation unit, an ozone treatment unit and a biological activated carbon treatment unit. An explanatory diagram thereof is shown in FIG.
【００２１】 上水や下水や冷却循環水などの処理対象目的の水を電気水垢処理器４で定電流 電気分解すると、水中に溶解しているＣａ2+及びＭｇ2+などが陰極に電析される ことで除去される。When the water to be treated such as tap water, sewage or cooling circulating water is electrolyzed at a constant current by the electric scale treatment device 4, Ca 2+ and Mg 2+ dissolved in water are electrodeposited on the cathode. Will be removed.
【００２２】 また炭酸やその塩類の電離によるＣＯ3 2-やＨＣＯ3 -は陽極で酸素や二酸化炭 酸や水素となり、脱気装置５によって脱気される。尚、図示省略した排ガス注入 装置はこの排ガスを、後述するようにオゾン処理された処理対象水に注入する。 電気水垢処理された水はオゾン処理器６に導入され、オゾン発生装置７により 生成したオゾンガスがオゾン処理器中の散気管８を介して微細な気泡となってオ ゾン処理器内の電気水垢処理後の水中に拡散して溶解する。Further, CO 3 2− and HCO 3 − by ionization of carbonic acid and its salts become oxygen, carbon dioxide and hydrogen at the anode and are degassed by the degassing device 5. An exhaust gas injection device (not shown) injects this exhaust gas into the water to be treated which has been subjected to ozone treatment as described later. The water subjected to the electric scale treatment is introduced into the ozone treatment device 6, and the ozone gas generated by the ozone generator 7 becomes fine bubbles through the diffuser pipe 8 in the ozone treatment device to treat the electric scale treatment in the ozone treatment device. Later it diffuses and dissolves in water.
【００２３】 この際、電気水垢処理後の水中にはＣＯ3 2-、ＨＣＯ3 -、Ｃａ2+、Ｍｇ2+及び 溶存酸素や炭酸ガス（二酸化炭素）が電気分解によって除去されているので、未 処理の場合と比較してオゾンガスの溶解度が大きく、その結果、ＯＨラジカルが 効率よく生成する。At this time, since CO 3 2− , HCO 3 − , Ca 2+ , Mg 2+, and dissolved oxygen and carbon dioxide (carbon dioxide) are removed by electrolysis in the water after the electric scale treatment, The solubility of ozone gas is higher than that in the untreated case, and as a result, OH radicals are efficiently generated.
