ポリ乳酸エステルからの水素供給による地下水中汚染物質の嫌気性微生物分解の促進(<小特集>汚染地盤の修復)

概要

In this study, a hydrogen release compound (HRC^<TM>), which is composed of polylactate ester, was injected into the contaminated aquifer in order to prevent the groundwater contaminated with tetrachloroethylene and its daughter products from flowing out of the industrial plant. It was expected that the injected HRC^<TM> would serve as nutrition for indigenous microorganism and enhance the biodegradation of contaminants in the groundwater. Groundwater monitoring results showed that anaerobic biodegradation of chlorinated contaminants was obviously accelerated by the HRC^<TM> injection and that the half-1ives of contaminants were shortened significantly. This field example suggests that this in-situ technique can be effectively applied to Japanese soil and groundwater.
