Abstract
<P>PROBLEM TO BE SOLVED: To simplify the cleaning for recycle purification of water of a reservoir in a purification plant, purification tank, water tank or the like, and to remove trihalomethane and bromate ions which are byproducts generated when sterilization is performed at the purification plant with trichloroethylene. <P>SOLUTION: In a manufacturing method of ceramic tiles and ceramic balls, even an anaerobic microorganism group(photosynthetic bacteria, lactic acid bacteria or the like) is enclosed in ceramics or the like and fired at a high temperature (1,000°C or higher) in an oxygen-free condition, the characteristics are never lost. The microorganisms are reduction fired with a mixture of titanium oxide (Tio<SB>2</SB>), thereby decomposing hazardous substances adsorbed in the ceramics. Thus, the reduction action of a photocatalyst by titanium oxide and ultraviolet ray decomposes the hazardous substances in the water. <P>COPYRIGHT: (C)2005,JPO&NCIPI
Description
この光合成細菌・乳酸菌等の嫌気性微生物は、無酸素状態に於いて高温１０００℃になってもその特性を失わず、この液体に酸化チタン（Ｔｉｏ２）を混合したものをセラミックに混ぜ還元焼成（８００℃以上）すれば、水の処理剤としてトリハロメタンや有機物の分解に利用できる。These anaerobic microorganisms such as photosynthetic bacteria and lactic acid bacteria do not lose their characteristics even when the temperature reaches 1000 ° C. in an anaerobic state, and this liquid is mixed with titanium oxide (TiO 2 ) and mixed with ceramic. If it is (800 degreeC or more), it can utilize for decomposition | disassembly of trihalomethane and organic substance as a processing agent of water.
水の汚染物質や殺菌・有機物を分解するために、今まで塩素やオゾン等の酸化処理が利用されていますが、その副生成物として、トリハロメタンや臭素酸イオン等が生成する。In order to decompose water pollutants, sterilization and organic matter, oxidation treatments such as chlorine and ozone have been used so far, but by-products such as trihalomethane and bromate ions are produced.
従って、この様なトリハロメタンや臭素酸イオン汚染有機物等も、酸化チタンの光触媒による分解と光合成細菌・乳酸菌等の浄化作用で継続的に汚染物質の分解・浄化ができる。Therefore, such trihalomethane and bromate ion contaminated organic substances can be continuously decomposed and purified by the photocatalytic decomposition of titanium oxide and the purification action of photosynthetic bacteria and lactic acid bacteria.
本発明は、有機汚染物や地下水汚染問題となっている、トリクロロエチレンや浄水場等で殺菌・酸化処理の際の副生成物トリハロメタン等は、セラミック板やセラミックボールに触れる際、自然光や蛍光灯に含まれる紫外線（３００ｎｍ〜４００ｎｍ）に当たると光触媒分解反応がおこり分解され、又セラミックに吸着された、汚染物質は、光合成菌・乳酸菌等嫌気性菌群の働きにより分解される。In the present invention, trichlorethylene, which is a problem of organic contaminants and groundwater contamination, and by-products such as trihalomethanes during sterilization and oxidation treatment in water purification plants, are used as natural light and fluorescent lamps when touching ceramic plates and ceramic balls. When exposed to the contained ultraviolet rays (300 nm to 400 nm), the photocatalytic decomposition reaction occurs and is decomposed, and the contaminants adsorbed on the ceramic are decomposed by the action of anaerobic bacteria such as photosynthetic bacteria and lactic acid bacteria.
淡水魚を飼育している水槽（６０ｃｍ）で浄化フィルター代わりに厚さ１０ｍｍ×１０ｃｍ角のセラミックタイルを敷き、水槽の底面にも直系１．５ｃｍのセラミックボールを３０個並べ、照明は４０ｗの蛍光灯１燈を１日８時間つけ３ケ月余りテストした結果、通常はガラス壁面に緑色の苔が付着し汚れが目立つが、今だ初期の状態を保っている。Instead of a purification filter, a 10mm x 10cm square ceramic tile is placed in the aquarium (60cm) where freshwater fish are bred, and 30 direct 1.5cm ceramic balls are arranged on the bottom of the aquarium. As a result of testing for 1 month 8 hours a day for about 3 months, green moss usually adheres to the glass wall and the dirt is conspicuous, but the initial state is still maintained.
