Description

（動作）
図１〜３に示すように、原子力発電プラント１０１で発生した汚染水は、配管４を経由して汚染水タンク１に導かれ、汚染水タンク１に貯留される。汚染水タンク１に貯留された汚染水は、汚染水配管６を経由してｐＨ緩衝塔２に導かれる。ｐＨ緩衝塔２に導かれた汚染水は、複数の緩衝材カートリッジ２０Ａ，２０Ｂ，２０Ｃ，２０Ｄを流通しつつ、ｐＨ緩衝材２１の作用によりｐＨが調節される。ｐＨ緩衝塔２においてｐＨが調節された汚染水は、汚染水配管８を経由して吸着塔３に導かれる。吸着塔３に導かれた汚染水は、複数の吸着材カートリッジ１７Ａ，１７Ｂ，１７Ｃ，１７Ｄを流通しつつ、吸着材１８の作用により汚染物質が吸着され除去される。吸着塔３において汚染物質が吸着され除去され汚染水は、処理水配管１０を経由して汚染水処理設備１００から排出される。 (Operation)
As shown in FIGS. 1 to 3 , the contaminated water generated in the nuclear power plant 101 is guided to the contaminated water tank 1 via the pipe 4 and stored in the contaminated water tank 1. The contaminated water stored in the contaminated water tank 1 is guided to the pH buffer tower 2 via the contaminated water pipe 6. The pH of the contaminated water guided to the pH buffer tower 2 is adjusted by the action of the pH buffer material 21 while flowing through the plurality of buffer material cartridges 20A, 20B, 20C, and 20D. The contaminated water whose pH is adjusted in the pH buffer tower 2 is guided to the adsorption tower 3 via the contaminated water pipe 8. The polluted water introduced to the adsorption tower 3 is adsorbed and removed by the action of the adsorbent 18 while circulating through the plural adsorbent cartridges 17A, 17B, 17C, 17D. Contaminants are adsorbed and removed in the adsorption tower 3 and the contaminated water is discharged from the contaminated water treatment facility 100 via the treated water pipe 10.
