摘要
受污染沉积物汞的释放已成为湖泊水体汞的重要污染源之一。通过沉积物原状柱的室内培育实验,对微生物、氧化还原电位对沉积物汞释放的影响进行了研究。实验表明氧化还原条件和微生物都是沉积物汞释放的重要因素,厌氧条件初期以及微生物的活动都能促进汞的释放。
Releasing mercury in the Contaminated sediments has become one of the important sources of mercury in reservoir water.Through the cultivate experiment of the original sediments,the releasing mercury in controlling the microbial and REDOX potential factors were studied.It indicated that oxidation-reduction conditions and microbial activities are the important factor and can cause the release of mercury greatly in sediment column.
