METHOD FOR MANUFACTURING POTTERY AND PORCELAIN BLOCK FOR CONTAMINATED WATER TREATMENT, AND THE POTTERY AND PORCELAIN BLOCK FOR CONTAMINATED WATER TREATMENT
PROBLEM TO BE SOLVED: To reliably treat contaminated water which has been treated without removing tritium, not into contaminated water but into a solid, not by chemical treatment but by physical treatment.SOLUTION: A method for manufacturing a pottery and porcelain block A for absorbing radioactive contaminated water is as follows: a green body 1 consisting of semi-porcelain clay, coarse potter's clay, light-weight potter's clay, lime feldspar potter's clay, dolomitic potter's clay, etc. and mixed bodies to be burned and extinguished 2 such as chaffs, are made into a pottery and porcelain block raw material A0 by mixing appropriate water therewith; the pottery and porcelain block raw material A0 is formed as an appropriate solid object, then burned in a burning kiln whose temperature is set to about 600°C to about 800°C which is lower than the burning temperature for burning a pottery or porcelain; and places existing after the mixed bodies to be burned and extinguished 2 are extinguished are formed as spaces 2a for absorbing the radioactive contaminated water.
【課題】本発明は、トリチウムは除去できないで処理された汚染水を、化学的処理にたよらず、物理的処理によって、汚染水ではなく固体として確実に処理するために行うこと。【解決手段】半磁器土，粗陶器土，軽量陶器土，石灰長石質陶器土，白雲陶器土等の坏土１と、籾殻等の燃焼消失性混入物２とを、適宜な水を混入して陶磁器ブロック原料Ａ０とし、該陶磁器ブロック原料Ａ０を適宜な立体物として成形しておき、陶磁器としての焼成温度よりは低い温度として、約６００℃乃至約８００℃に設定して焼成窯にて焼成し、燃焼消失性混入物２を消失させてこの存在箇所を空隙２ａとして形成して、放射能汚染水を吸水するための陶磁器ブロックＡを製造する製造法としたこと。【選択図】図４
