POLLUTION COUNTERMEASURE METHOD USING ACTIVE CARBON
To provide a pollution countermeasure method, solving problems in conventional purification methods using a composite particle formulation composed of metallic iron and active carbon, with difficulty in setting an optimal quantitative ratio of metallic iron and active carbon according to objective pollution and difficulty in control of a purification period and reduction of purification cost, in which since a decontamination mechanism is only restricted to reductive dehalogenation reaction whose reaction rate is slow, the range of application of pollution species is extremely narrow, resulting in inefficient purification.SOLUTION: The present invention provides a high efficiency purification construction with suppressed construction risk and high versatility to a market, by binding a metallic iron particle and an active carbon particle to each other moderately in water with an optimal quantitative ratio of metallic iron and active carbon set according to an objective pollution in a condition of coprecipitation, and combining an oxidation reaction going in the presence of an oxygen compound in the front stage of the reductive reaction, thereby achieving enlarged applicable pollution species and high speeding.SELECTED DRAWING: Figure 2
【課題】従前技術での金属鉄と活性炭で構成される複合粒子製剤を用いた浄化は、対象汚染に応じた最適な金属鉄と活性炭の量比設定が困難であり、浄化期間の調整や浄化コストの低減に難を有していた。また、除染機作が、専ら反応速度が緩速な還元的脱ハロゲン化反応に限定されることから、汚染種の適用幅が極めて狭く、非効率な浄化であった。【解決手段】対象汚染に応じた最適な金属鉄と活性炭の量比が設定された金属鉄粒子と活性炭粒子を、水中にて共沈する条件にて両粒子を緩やかに結合させ、更に、酸素化合物の存在下で進行する酸化反応を還元反応の前段に組み入れた、適用汚染種の拡大と反応の高速化を図った、施工リスクが少なく、汎用性の高い、高効率な浄化施工を市場に提供する。【選択図】図２
